Monitor Shows Carbon Monoxide Spikes to 40,000 Parts Per Billion over California on February 26 — What the Heck is Going On?

Hint: it’s a glitch.


On February 26, The Global Forecast System model recorded an (unconfirmed) intense and wide-ranging carbon monoxide (CO) spike over the US West Coast. A region stretching from British Columbia, through Washington and Oregon, and on over most of California experienced CO readings ranging from about 5,000 parts per billion over the mountains of Southwestern Canada to as high as 40,000 parts per billion over Southern California. Very high peak readings appear to have occurred from Northern California near Eureka and along a line south and eastward over much of Central California to an extreme peak zone just north and west of Los Angeles near Palmdale.

For reference, these (unconfirmed) readings in the Nullschool Monitor were between 25 and 200 times above typical background CO levels of about 200 parts per billion and up to twelve times higher than second highest peak readings over polluted regions of China during the same period.

Major Spike Appeared in Just 3 Hours Starting February 25th

Human-based carbon monoxide sources are not generally known to produce spike readings so high and so wide-ranging over such a short interval of time. It would typically take a considerable emission many days to build up under a stagnant air mass. And, to this point, we do have a couple of dome high pressure systems which have tended to form near the California region over recent days. That said, surface winds in the region at 5-15 mph over most areas could hardly be considered stagnant. In addition, the current spike appears over an interval of three hours in the Nullschool data — going from zero coverage to covering all of California and parts of Nevada, Oregon, Washington and BC over that single short interval. It’s a very brief period for such a large and wide-ranging peak reading to appear so soon. One that would require a rather extraordinary pulse of pollution to produce the readings indicated on February 25-26.

Wildfires could produce a longer-term emissions spike under stagnant air as well. However, the wildfires now reported for California are small and isolated. They have flared, off and on, under drought conditions, for weeks without resulting in any significant large fire outbreaks or related major pollution spikes. So it appears unlikely that they are the source of the current burst. Other events related to the ongoing California drought may have had an impact (apparently, burning of desiccated trees from California’s orchards is currently quite widespread due to ongoing drought conditions remaining in place since 2012). However, such instances would have to have been very sudden and wide-ranging to produce the spike we saw on the 25th and 26th.  Canadian wildfires — of which there have been very small and low intensity hotspot events recently (noteworthy due to their anomalous appearance out of season, if not for their intensity)  — were very far from peak readings in California and did not produce even a moderate level of emissions (undetectable from the visible MODIS sensor).

The Earthquake Precursor Hypothesis

A final suspect for this preliminary observation (which has gotten much hype in social media circles over recent days) is geological. As the apparent spike in the monitor occurs over large fault lines, volcanoes, and above other active geological features along the US and Canadian West, it appears that activity within these features might have produced a brief if intense burp of this gas. Sulfur dioxide (SO2) readings — another geological gas — were also elevated in the monitor, with peak readings again appearing in Southwestern California.

It’s worth noting that no major US or Canadian geological organization has yet made any report on this particularly large CO spike. However, a piece of scientific research in Nature Asia, by K. S. Jayaraman notes that major CO and SO2 spikes may be an indication that future earthquake activity is on the way. According to Nature this kind of intense CO spike occurred prior to a 7.6 magnitude earthquake that shook Gujara in 2001 killing 20,000 people:

Singh said that CO levels were taken by an instrument onboard NASA’s Terra satellite — launched in 2009 — circling the earth in a polar orbit at a height of 705 km. The instrument measures CO concentrations at different heights and also computes the total amount of the gas in a vertical column of air above the earth surface.

Analysis of the satellite data showed a large peak in CO concentrations during January 19 and 20 — a week before the main earthquake event. On January 19, the total CO in the vertical column was also higher than usual. After the 26 January earthquake the concentration of the gas dropped.

According to the scientists, CO gas is forced out of the earth due to the build up of stress prior to the earthquake “influencing the hydrological regime around the epicentre.”

But before we tilt too far into alarmism on this particular possibility, we should consider the fact that the above paper appears to have had no confirmation or further comment in the sciences at this time. So the predictive usefulness of large CO spikes prior to earthquakes remains quite uncertain. And, as noted above, no major geological information outlet has made any warning or comment on earthquake risk.

Furthermore, there’s been no observed spike in earthquake activity along any of the major fault lines over the past week according to USGS observations. Contrary to what some irresponsible analysts have been implying, earthquake activity in the California region over the past 7 days was well within the normal range. At 161 over the past week, this small number is not indicative of any abnormal activity near the various active fault lines. Each year, Southern California alone experiences 10,000 earthquakes, most of which are so small that people don’t even feel them.

The US geological survey also maintains that:

There is no scientifically plausible way of predicting the occurrence of a particular earthquake. The USGS can and does make statements about earthquake rates, describing the places most likely to produce earthquakes in the long term. It is important to note that prediction, as people expect it, requires predicting the magnitude, timing, and location of the future earthquake, which is not currently possible.

Thus the apparent, current very large West Coast CO spike near major fault lines (and over regions suffering from what is now a very severe five-year drought) in this particular monitor remains a bit of a mystery.

Or is it all Just a Glitch?

Considering that all the wildfire and human potential sources for the CO pulse are unlikely to produce the spike in the Nullschool data, that we have no warning of potential impending geological activity from the major agencies, and that we have had no other reports from related agencies to confirm the spike, we should also consider that there may well be something wrong with the monitor. Artifacts can appear in the satellite model data and it’s not unheard of to get a spike reading due to other signals impacting how physical models interpret sensor data.

Carbon Monoxide Hourly Observations San Bernandino

(Hourly carbon monoxide observations in Central San Bernardino do not match high surface CO measures recorded by the GEOS 5 model. Similar lower atmospheric readings come from station observations throughout Southern and Central California. Image source: California AMQD.)

To this point, lack of confirmation at ground reporting stations for high CO readings appearing in the GEOS 5 monitor increase the likelihood that these high peak readings were a glitch or an artifact in the physical data. A cursory view of local warnings shows no local CO air quality alerts for the areas indicated in the Nullschool data set (You can view a list of the local monitors here). Analysis of this data also shows much lower CO readings from these stations in the range of 400 to 1200 parts per billion — quite a bit lower than what the GEOS 5 monitor is showing.

So what we have is one model showing a very high CO spike, but none of the related ground monitors picking it up. Since there are hundreds of ground stations in this region, it seems quite a bit less likely that there is something wrong with each of the readings coming from these stations than from the GEOS 5 model itself.

This begs the question — was there some kind of false positive that confused GEOS 5? Was there some other signal that tripped the model to show such a high reading? But to these points, a general lack of overall confirmation from the hundreds of ground sensors scattered across the region seems to point to the likelihood that such elevated readings in the GEOS 5 monitor were a glitch, an artifact, or a false reading for this atmospheric level.

UPDATED: Final Confirmation — It’s A Model Algorithm Error

Dr. Gavin Schmidt, head of GISS NASA, has confirmed the glitch in his twitter feed which you can read here. He notes:

The Elevated Carbon Monoxide concentrations in the GEOS 5 products since February 25 of 2016 are incorrect. They are the consequence of unrealistic CO emissions computed by our biomass burning algorithm, which is based on satellite observation of fires… GMAO is working to correct this problem.

An excellent further explanation has been given by Bryan, a blogger over at Of Tech and Learning. His explanation is as follows:

“It’s pure coincidence that at MOPITT resumed data collection over western North America while its operating temperature was still stabilizing. Had the instrument’s temperature remained unstable for a few days, it would have looked like the whole globe was erupting gas. If MOPITT has started collecting data over the south pole, open ocean, or some other obscure location, I doubt anyone would have noticed and made a big fuss. MOPITT uses light collected in the infrared part of the spectrum. Based on Terra’s system status, the CO, CO2 and SO2 data collected by MOPITT on the 25th and 26th of February should be highly suspect. On the Earth map, the CO, CO2, and SO2 levels spike sometime between 1pm and 4pm Pacific time on Feb. 25th, which is between 2100 UTC on the 25th and 0000 UTC on the 26th. This is precisely during the time window when MOPITT’s operating temperature is still unstable.”

So a glitch does appear to be the cause of the current CO spike in the Nullschool data.

2 C Coming On Faster Than We Feared — Atmospheric Methane Spikes to Record 3096 Parts Per Billion

It’s essential that policymakers begin to seriously consider the possibility of a substantial permafrost carbon feedback to global warming. If they don’t, I suspect that down the road we’ll all be looking at the 2°C threshold in our rear-view mirror.Robert Max Holmes


Unraveling the global warming puzzle is simple at its face, complex when you pierce the surface.

We know that burning fossil fuels, that the activity of mining coal, fracking for gas, and drilling for oil all result in dangerous greenhouse gas emissions. We know that the vast majority of these warming gasses are coming from fossil fuel based sources. We know that, now, the burning and mining and fracking and drilling have pushed atmospheric CO2 above 405 parts per million and the global concentration of all CO2 equivalent gasses to an amazing 485 parts per million CO2e (levels not seen in at least 15 million years). And we know that the heat re-radiated by these gasses has warmed the world by about 1 C above 1880s levels — forcing weather patterns to change, seas to rise, ocean health to decline, and setting off a wave of die offs in the animal world while increasing the near-term risk of hunger, spreading tropical disease, and mass displacement in the human world.

Radiative Forcing

(Heat added to the Earth’s atmosphere by fossil fuel emitted gasses like CO2 and Methane are measured in watts per meter squared. A yardstick known as radiative forcing [RF]. In the above graph by IPCC, we can see the estimated levels of radiative forcing from each greenhouse gas and total net human heat forcing upon the Earth atmosphere as of 2011. It’s a measure that may also need to start adding in the RF of feedback greenhouse gasses as the 21st Century progresses. Image source: RealClimate.)

We know many of the names of these other gasses — methane, nitrous oxide, and chlorofluorocarbon. And some of the others — like sulfur hexaflouride — many of us haven’t yet heard of. But the big name, the primary warming agent, is carbon dioxide — responsible on its own for the majority of the overall heat forcing currently. A gas so important to long term warming that NASA has called it ‘the thermostat that controls Earth’s temperature.’

All this is pretty simple and straightforward. But it’s when we start looking at what are called amplifying feedbacks — the Earth System Sensitivity responses to human forced warming — that things really start to get dicey. And wrapped up in the Earth System Sensitivity equation is methane — a greenhouse gas with the ability to strongly influence global temperatures over rather short time-frames.

Methane Spikes to Over 3,000 parts per Billion

On February 20th, for about 12 hours, the NOAA METOP measure recorded a major atmospheric methane spike in the range of 3,096 parts per billion at 20,000 feet in altitude. This was the first time that any measure had recorded such a high methane spike and the first time any measure had exceeded the 3,000 parts per billion threshold. For context, just two years ago, a methane spike in the range of 2,660 parts per billion would have been significant. Now, we’re getting peak readings that are more than 400 parts per billion higher than that previous maximum threshold.

Metop methane

(METOP showed a record 3,096 parts per billion atmospheric methane spike on February 20 of 2016. Thus far, this was the largest such spike ever recorded in the NOAA measure. One that far exceeded a global atmospheric average of around 1830 parts per billion. Image source: NOAA/METOP.)

It’s a pretty ominous signal — especially when you consider the fact that global atmospheric methane averages are in the range of 1830 parts per billion. The recent major spike was about 1170 parts per billion higher. In other words — a pretty extraordinary excession. It’s evidence that the methane sources of the world are growing more vigorous in their output. And when you consider the fact that methane — on a molecule-by-molecule comparison to CO2 — traps about 80 times more heat over the decadal timescale, large additions of methane on top of an already dangerous CO2 forcing is certainly cause for some concern. An issue that may further speed the already rapid pace of human-forced warming such that we become at risk of hitting the 1.5 C and 2 C thresholds sooner than expected. Outcomes we should urgently be working to avoid — by cutting the human-based emission as rapidly as possible at this time.

The Usual Suspects — Fossil Fuel Based Activity

Perhaps still more concerning is the fact that we really don’t know exactly where this significant methane spike is coming from.

We do, however, have a long list of usual suspects. The first, of course, would be from any number of very large and dangerous fossil fuel emission sources. China, with its massive methane belching coal mines, gas infrastructure, and dirty coal burning facilities would be a prime suspect. Mongolia, where equally sprawling coal and gas facilities operate is another likely hot spot. Russia — with its vast and leaky oil and gas fields. The Middle East — which is choked with fossil fuel infrastructure. Europe — where many of Russia’s pipelines terminate and where many nations burn a high-methane brown coal. And the United States — where the geologically destructive practice of fracking has now also recently and greatly increased methane emissions.

Unusual Suspects — Permafrost and Clathrate Warmed by Fossil Fuel Emissions

Looking at the very low resolution METOP graphic above, we find a number of methane hot spots around the globe. And many of these hot spots do coincide with our usual suspects list. But others are well outside the range we would typically expect. Far up in the north. Over the tundra and the Arctic Ocean where few major fossil fuel burning or extraction facilities now exist. There, somewhat ironically, great piles of permafrost spreading over millions of square miles and sometimes mounding up as thick as two miles are thawing due a greenhouse gas heat forcing from fossil fuel burning often happening hundreds or thousands of miles away. This thawing permafrost is filled with organic material. And when freed of its icy prison it is exposed to the world’s elements and microbes. These forces then go to work turning the organic carbon in that permafrost into carbon dioxide and methane.

This is rather bad news. In total, more than 1,300 billion tons of carbon are locked away in the permafrost soils. And carbon emissions from permafrost make an already bad heat forcing coming from fossil fuel burning even worse.

Barrow methane

(Atmospheric methane levels as recorded by various reporting stations and global monitors have been rising more rapidly during recent years. In the Arctic, atmospheric readings have tended to remain above the global average — an indication that local emissions are generating an overburden for the region. Image source: NOAA ESRL.)

But if all the human emissions and potential permafrost emissions weren’t bad enough, we have one more major carbon source in the Arctic to consider — methane hydrate. A controversial potential methane release source to be certain. But a very large one that we would be remiss to ignore. Due to the fact that the Arctic has remained very cold overall for the past 3 million years of long ice ages and brief interglacials, this massive store of carbon has been given the opportunity to build up within the relatively shallow and now swiftly warming Arctic Ocean waters and even beneath large sections of now-thawing permafrost. Much of this carbon is in the form of the frozen ice-methane called hydrate. And as the Arctic Ocean warms and sea ice recedes to expose blue ocean to the heating of the sun’s rays for the first time in hundreds of thousands of years, there is concern among some scientists that a not insignificant amount of that submerged frozen methane will release, pass the ocean-atmosphere or thawing permafrost boundary, and add more heat forcing to the world’s atmosphere. The shallow sea of the East Siberian Arctic Shelf has been identified by some to contain as much as 500 billion tons of carbon in the form of frozen methane. And a fossil fueled heating of the Earth may be just now risking amplifying feedback level releases from this large clathrate store along with a number of other very large stores scattered all across the Arctic Ocean basin and on throughout the global ocean system.

A Clearer Picture? Or One Far More Complex?

So who among all the various suspects — usual and unusual — may be responsible for the record methane spike now showing up in the METOP measure?

Before we attempt to answer this question, let’s pull in another methane graphic — this one from the Copernicus Observatory:

Global Surface Methane Readings Copernicus

(The February 25 Copenicus methane graphic tracking surface methane readings gives a higher resolution indication of surface methane readings than the NOAA METOP measure. This second measure provides some confirmation of an Arctic methane overburden even as spike sources from human emissions become more readily apparent. Omnious spikes also apparently come from wildfires in the tropics and from regions in the Arctic near Yamal, Russia, Northern Scandinavia, the Barents and Kara seas. Image source: The Copernicus Observatory.)

Here we can see the range of surface methane readings according to Copernicus. A higher resolution image that may provide us with a better idea of the point-source location for daily global methane spikes. Here we see that the major methane sources are predominantly China, Russia, the Middle East, Europe, the United States, India, Indonesia, Fires in Africa and the Amazon, and, finally, the Arctic.

Though the Copernicus measure doesn’t show the same level of Arctic overburden as what has tended to show up in the METOP measure, it’s a confirmation that something in the near Arctic environment is generating local spikes in above 1940 parts per billion for large regions of this sensitive zone.

The Copernicus measure, as noted above, also shows that the human spikes are quite intense, remaining the dominant source of methane emissions globally despite a continued disturbing overburden in the Arctic. Spikes in Africa, the Amazon, and Indonesia also indicate that declining rain forests and related fires in these tropical zones are also probably providing an amplifying feedback to the overall human emission.

Given this month’s spikes and the overall disposition of surface methane readings around the globe, it does appear that the large human base methane emission is being enhanced by feedbacks from local emissions from carbon stores both in the tropics and in the Arctic. This enhancement signal, though somewhat smaller than the fossil fuel related signal in some measures, is concerning and hints that Robert Max Holmes’ warning at the top may be all-too-relevant. For Earth System feedbacks to massive and irresponsible fossil fuel emissions appear to already be starting to complicate our picture of a warming Earth.

As a Titanic El Nino Begins to Fade, What Fresh Trouble Will a Record Warm World Bring?

Today the globe is feeling quite a bit of backlash from a human-warmed sea surface and atmosphere. As it ends up, Dr. Kevin Trenberth was right. Deep ocean warming set off by heat-trapping fossil fuel emissions and building up through the first two decades of the 21st Century did re-surge from the depths to haunt us in 2014, 2015 and 2016. In that wrenching global climate system shift to the hot side of natural variability, a titanic El Nino emerged. It was one of the top three strongest such events in the modern record. One that by NOAA’s measure appears to have tied the extreme event of 1998 at its peak intensity.

ONI sea surface temperature anomalies in Nino 3.4

(Sea surface temperature departure from average in the benchmark Nino 3.4 zone shows surface ocean heat anomalies for the 2015-2016 El Nino equaled peak 1997-1998 values. Image source: NOAA/CPC.)

Expected Heat, Drought, and Storms Together With a Few Ominous Surprises

This event did push the world into extreme warmth even as predicted related severe weather flared in some of the typical regions. Annual average global temperatures rocketed to about 1.06 C above 1880s baselines during 2015 even as monthly departures hit 1.2 to 1.3 C or more higher than the same benchmark during December and January.

Amidst this great upheaval of global heat, the world also experienced yet one more wave of freak droughts (this time over Northern South America, the Caribbean, large swaths of Africa and Southeast Asia), heat-related mass casualty events, floods, and strongest hurricanes on record. Arctic and global sea ice measures are once again plunging to new record lows. A global coral bleaching event, perhaps the worst such instance ever experienced, was also set in motion.

The predicted patterns and potential worse-case events (such as heatwave mass casualties, coral bleaching, and sea ice loss) were also contrasted by a number of surprises. The first and perhaps most ominous was the failure of El Nino to bust the California drought. Though the West Coast of the US did experience a number of storms, the pattern was more typical of normal Winter moisture for the Northwestern US even as drought continued throughout the Southwest.  Moisture instead tended to split fire-hose fashion — with storms either cycling northward into Alaska, the Aleutians, or the Bering Sea, or south over Southern Mexico or Central America, up across the Gulf and on out into a particularly severe storm zone forming in the North Atlantic.

30 day precipitation anomaly shows southwest drought continuing

(Over the last 30 days the southwest drought re-emerged as a blocking pattern again began to take hold over Western North America and the Eastern Pacific. Image source: NOAA/CPC.)

This continued loss of moisture for the US Southwest despite a record El Nino is particularly apparent in the Climate Prediction Center’s most recent precipitation anomaly measure for the last 30 days. Here we find that large parts of Central and Southern California have received just 10 to 50 percent of typical rainfall for this period. Coupled with 1-3 C above average temperatures for the month, this loss of rainfall during what would typically be California’s wettest period has come as a disappointment to many who were hoping a strong El Nino would help break the state out of a crippling drought. Now, the window for late Winter and early Spring rains is starting to close even as the blocking pattern appears to be strongly re-established in both the present weather pattern and in the forecast model runs.

But perhaps the biggest surprise coming from this El Nino year was a set of weather events in the North Atlantic that were likely more related to climate change. There, severe storms hammered a flood-beleaguered UK as a greatly distorted Jet Stream heaved Equatorial heat and moisture northward — rushing it up over a ridiculously warm and apparently backed-up Gulf Stream before slamming it on into a likely Greenland ice melt-outflow related cool pool. There the heat and moisture collided with cold to produce the epic storms that then vented their fury upon the UK.

Warm Arctic Storm

(December 29th saw temperatures rise above freezing at the North Pole — the first time temperatures have warmed so much for this high Arctic region so late in the year. Image source: Earth Nullschool.)

During one such event, a daisy chain of heavy-hitting North Atlantic lows hurled high winds, heavy rains and epic surf at the UK even as the meridional flow set up by these powerful beasts shoved above-freezing temperatures all the way to the North Pole during late December. Yet one more unprecedented and unexpected event during a record warm year. One that looks more like a human forced warming which has overcome the traditional influences of El Nino, rather than an El Nino related impact in itself.

As El Nino Fades, Equatorial Heat Tends to Move Pole-ward

Though we may see these two events — the failure of El Nino to provide heavy rains to the US West Coast, and the massive northward pulses of storms, heat and moisture hitting the North Atlantic — as unrelated, the twain patterns appear to be linked to an ongoing polar amplification. Overall, heat within the Arctic has tended to weaken the Northern Hemisphere Jet Stream over these two zones. And even during El Nino, when the Jet would have typically strengthened, we have continued to see high amplitude wave patterns forming over these regions.

But as El Nino weakens and the Equator cools, the Jet Stream would tend to slow even more. Such an atmospheric state would tend to further exaggerate already significant Jet Stream wave patterns — transferring still more low-Latitude heat poleward. In addition, the ocean gyres tend to speed up as El Nino fades or transitions to La Nina. The result is an amplified pulse of warmer waters emerging from southern Latitudes and entering the Arctic.

It’s for these combined reasons — tendency to amplify south to north atmospheric heat transfer into the Arctic post El Nino and tendency to flush warmer waters toward Arctic Ocean zones during the same period that it appears we are entering a high risk time for potential new sea ice melts and possible related Greenland land ice melts during 2016 and 2017.

Hot Blobs

(Northeastern Pacific Hot Blob remains at high intensity even as its size is predicted to expand through July. Meanwhile, very warm sea surface temperatures are predicted to remain in place off the Eastern Seaboard. The net effect of these two hot blobs may be to shove the Jet Stream far northward over North America during the summer of 2016 — potentially increasing the risk of widespread and potentially record heat and drought. Predicted very warm sea surfaces in the region of the Barents and Greenland seas — in excess of 3 C above average for a large region — is also cause for concern. This is not only due to risk for sea ice loss through this zone, but also due to its potential to set off blocking pattern and heat dome formation over Eastern Europe and Western Russia. Image source: NOAA/CFS.)

In addition, we are at serious risk of seeing the high amplitude blocks and wave patterns re-establish and persist, especially in the zone over Western North America were a related Northeastern Pacific Hot Blob is expected to restrengthen as El Nino fades. In fact, large regions of the US may fall under record to near record heat and drought this summer due to the combined influences of two very warm ocean zones surrounding her shores. Models now indicate a particular late spring drought risk for the Great Lakes region as well as an extended period of far above average temperatures for pretty much all of the Continental US during summer. Meanwhile, predicted above average spring-time precipitation for the Southwest appears less and less likely to emerge.

Finally, extreme above average sea surface temperatures are predicted to intensify over the Barents and Greenland seas through to end of Summer 2016. This is an area to watch. The added ocean heat would tend to pull the Jet Stream northward over Eastern Europe and Western Russia — generating risk of heatwaves and drought for this region even as Central Asia fell under risk of floods. Long range CFS precipitation and temperature model runs for Europe have not yet picked up this risk. However, given the intensity of heat predicted for Barents sea surfaces and the related tendency of warmth over oceans and in the far north to influence the formation of blocking patterns, heat domes, and high amplitude troughs, it’s worth keeping a weather eye on the situation.

El Nino to Weaken and Then Return; or is a Shift to La Nina Now Under Way?

Related to a polar and ocean warming-enhanced tendency to generate high amplitude Jet Stream waves — as well as associated persistent heatwaves, droughts, and floods — is the heat balance of the Equatorial Pacific. Strong El Ninos, or even a tendency to remain in or near an El Nino state, has historically aided in the breaking of new record global high temperatures when linking up to the greenhouse gas warming trend. Meanwhile, the shift toward La Nina has tended to enhance a range of global heating related issues including record rainfall events and large injections of heat toward the poles in the drop off from El Nino to La Nina.

The cause for increased risk of major precipitation events is due to the fact that El Nino is providing a massive moisture bleed into the atmosphere at times of peak intensity. With the current El Nino topping out near record levels and with global temperatures at above 1 C higher than 1880s averages, global atmospheric moisture levels are hitting new record highs at this time. If global temperatures subsequently drop by around 0.1 to 0.2 C during a transition into La Nina (into a range about 0.9 to 0.8 C hotter than 1880s values) then the atmosphere will be unable to keep a larger portion of that extra moisture in suspension and it will fall out as precipitation — primarily wringing out where the major trough zones tend to set up. We should be very clear here in saying that the drought risk related to a global warming intensification of ridge and heat dome formation is not reduced during such instances — just that the risk of extreme precipitation events is enhanced.

Russian Heatwave Pakistan Floods Jet Stream

(During 2011, as the 2010 El Nino faded into La Nina conditions, a high amplitude wave in the Jet Stream set off record heat, drought and wildfires over Russia even as Pakistan was hit by a month-long deluge that was the worst rainfall event for the region in the last 1,000 years. La Nina’s tendency to wring excess water out of the atmosphere can enhance the risk for such events to occur in a warming climate state. Image source: NASA.)

As for risks to sea ice, we’ve provided some of the explanation above. However, it’s also worth noting that the mobility of heat poleward tends to be enhanced during the periods when El Nino drops off toward La Nina. During these times, Equatorial heat tends to propagate in wave fashion toward the Poles — especially toward the Northern Hemisphere Pole which has already lost its strong Jet Stream protection warding away warm air invasions.

These two factors are major issues when considering whether La Nina or an ENSO Nuetral state will appear post El Nino during 2016. But there is a third — rate of global temperature rise. Though the primary driver of global warming is a massive human fossil fuel emission, the response of the world ocean system can significantly wag the rate of atmospheric temperature increases on a decadal time scale. If the ocean tendency is for La Nina, this would tend to somewhat suppress the overall decadal rate of temperature increase — and we saw this during the 2000s. But if the ocean tendency is to produce El Ninos (in a switch to a positive Pacific Decadal Oscillation, as appears to be happening now), then the overall pace of global atmospheric temperature increase would tend to be enhanced.

La Nina Emerges

( IRI/CPC consensus model runs show a drop off to a weak La Nina by late in the year. However, CFS model runs [image below] have shown a tendency to predict a resurgence of El Nino conditions by Fall. Image source: NOAA/CPC.)

To this point we find that the official model forecast consensus published by NOAA (IRI/CPC figure above) shows a transition to ENSO neutral states by May, June, and July which then proceeds on to a very weak La Nina by Fall. In such a drop off, we would likely still see record global high temperatures during the period of 2016 (in the range of 1.03 to 1.15 C above 1880s values).

However, the late 2016 and 2017 tendency for temperatures to recede from new record highs would be somewhat enhanced (likely dropping below the 1 C above 1880s mark in 2017 or 2018 before again making a challenge to the 2015-2016 record with the potential formation of a new El Nino in the 3-5 year time-frame of 2019 through 2021). It’s worth noting that this scenario shows an increased risk of a stronger warm air pulse heading toward the Northern Polar zone together with added fuel for extreme precipitation events as global temperatures would tend to drop off more swiftly from late 2015 and early 2016 peaks.

El Nino Continues

(CFSv2 model run — shows El Nino continuing on through the end of 2016. Over recent months, the CFSv2 series has shown a high accuracy. However, NOAA’s current forecast preference is for the IRI model set predictions [previous image above]. Image source: NOAA/CPC.)

In contrast, the CFSv2 model forecast from NOAA (above image) shows El Nino only weakening through to July and then re-strengthening in the October-November time-frame. This CFS model scenario would result in higher atmospheric temperatures in 2016 — practically guaranteeing a lock on an unprecedented three back-to-back-to-back record warm years for 2014, 2015, and 2016. But such a scenario — implying that the Pacific Ocean had entered a new period of El Nino tendency — would also tend to keep atmospheric temperatures nearer to the newly established record highs.

Under the CFSv2 scenario, we may expect annual average global temperatures to rise as high as 1.08 to 1.2 C above 1880s values during 2016 (a very extreme departure and one uncomfortably close to the 1.5 C warming mark). These extreme values would, perhaps, recede to around between 0.9 and 1.1 C during 2017 so long as the second El Nino pulse did not remain in place for too long. However, if the bounce back toward El Nino conditions was strong enough in late 2016, there would be an outside chance that the globe may experience not 3, but an absolutely obnoxious 4 back-to-back record warm years.

NASA temperature trend

(During 2015 global annual temperature rocketed to above 1 C hotter than 1880s values. There’s at least an even chance that 2016 will be hotter still. Considering the considerable heating tendency imposed by a fossil fuel-forced warming of the world, how much worse can it get during the 21st Century’s second decade? Image source: NASA GISS.)

Meanwhile, the warm air pulse heading toward the poles may be somewhat muted under this scenario. A statement that should be qualified by the fact that we’ve already seen a substantial amount of El Nino heat heading poleward during the present event. In addition, potentially heavy rainfall events may not receive the added oomph of a decent global temperature drop to wring out more moisture. A statement that requires the further qualification that overall atmospheric moisture loading is enhanced by rising global temperatures — so comparatively less heavy rainfall is a relative term here.

At this time, NOAA favors a transition to La Nina forecast stating:

“A transition to ENSO-neutral is likely during late Northern Hemisphere spring or early summer 2016, with a possible transition to La Nina conditions by fall.”

However, it’s worth re-iterating that the CFSv2 model forecasts have been quite accurate in predicting the path of the current record El Nino to date.

Human Hothouse Spurs Longest Coral Die-Off on Record

The big coral die-off began in the Western Pacific as a massive ocean temperature spike built up during 2014. Back then, ocean heat accumulation had hit a very high ramp. A vicious, century-and-a-half long increase in atmospheric greenhouse gasses re-radiated greater and greater portions of the sun’s energy hitting the Earth — transferring the bulk (about 90 percent) to the world ocean system.

Major Coral Bleaching Event

(A report out today from AGU finds that the world is now experiencing its longest coral die-off event on record. Image source: AGU.)

By 2015, as one of the strongest El Ninos on record began to extend its influence across the globe, a broad region stretching from the Western Pacific, through the Central Pacific and on into the Eastern Pacific and Caribbean were all experiencing mass coral die-offs. Into early 2016, die-off events again expanded taking in Australian waters and sections of the Indian Ocean off East Africa and Western India.

After 20 months of ongoing coral mortality, we are now in the midst of the longest coral die-off event on record — one of only four such events that the world has ever experienced.

The Fourth Major Coral Die-Off

Researchers have long known that corals are sensitive to changes in ocean temperature. A rise in ocean water readings by as little as 1 degree Celsius above average peaks over the period of a month can be enough to set off a life-threatening condition called a coral bleaching event. According to a recent report in AGU:

The bleaching, or whitening, occurs when the corals expel the symbiotic algae that live in their tissues. Without the algae, corals lose a significant source of food and are more vulnerable to disease. In a severe bleaching event, large swaths of reef-building corals die. This causes reefs to erode, destroying fish habitat and exposing previously protected shorelines to the destructive force of ocean waves.

The typical bleaching threshold for most corals tends to be in the range of 29-30 degrees Celsius or about 84-86 degrees Fahrenheit over an extended period. And with the world ocean surface approaching a range near 1 C above 1880s averages, this threshold is hit more and more frequently — putting corals at greater and greater risk.

(World Resources Institute Published the above video in 2012 as a survey of, then current, threats to global coral reef systems. By 2030, heating of the world ocean system, ocean acidification and global warming related dead zones will provide an extreme existential challenge to the world’s beautiful and diverse coral reef systems.)

Prior to the 1980s, widespread coral bleaching events were unheard of. Though isolated events occurred, the world ocean system had not yet warmed enough to put corals at major risk. However, by the 1980s global ocean temperatures had begun to rise into ranges at which peak ocean warming periods could put corals in the firing line for major, globe-spanning die offs.

The first such major, global coral die-off occurred during the, then record, 1982-1983 El Nino. At the time this event was unprecedented. And it held the dubious standing as the only such event until the 1997-1998 Super El Nino set off a similar, though longer-lasting mass die off. By the late 2000s, global ocean temperatures had again risen — hitting marks high enough to enable a weak 2010 El Nino to set off the third mass coral die-off.

The fourth mass die off began in 2014 prior to the most recent super El Nino — which has only exaggerated and lengthened its impact. It is now the longest lasting coral die-off ever recorded. And researchers expect it to continue on through at least much of 2016 and possibly into 2017.

Corals Entering a Period of Killing Heat

As the oceans are predicted to continue warming over the next few decades, corals are expected to come under ever-worsening stress. A recent report by the World Resources Institute (WRI) found that regions experiencing the current mass die-off were 70-90 percent likely to experience similar events at a frequency of once every two years by 2030. And a much larger region was expected to have a 50 to 70 percent risk of experiencing a bleaching event over a two year time-frame.


(World Resources Institute in 2012 found that mass coral bleaching and related die-off would occur with extraordinary frequency post 2030. Image source: The World Resources Institute.)

By the 2050s, under business as usual fossil fuel burning, WRI expects that much of the world’s temperate and tropical oceans would experience coral bleaching events bi-annually.

Taking this stark prediction into account we find that the threat to corals over the coming decades will eventually exceed El Nino periodicity and become common during most ocean climate states. The current, likely two year to 30 month, coral die off should serve as a warning for the worse and more frequent hits to corals that will, sadly, be stacking up over the coming decades. Eventually, mass coral die-offs in the continually warming world ocean will become continuous and ubiquitous unless the current trend somehow draws swiftly to a halt.

In addition, given an expanding ocean acidification proceeding southward from the poles and more and more widespread zones of ocean anoxia (areas of water containing very little oxygen), what we are seeing is that threats to coral health are rapidly multiplying due to influences directly related to human-forced climate change.

A Monster 2016 Arctic Melt Season May Have Already Begun

“Hell is empty… all the devils are here.” William ShakespeareThe Tempest.


We have never seen heat like this before in the Arctic. Words whose meaning tends to blur due to the fact that, these days, such events keep happening over and over and over again.

Ever since at least the 1920s, the Arctic has been warming up due to a destructive and irresponsible human greenhouse gas emission. And, over recent years, the Arctic has been warming more and more rapidly as those dangerous emissions continued to build on into the 21st Century. Now the Earth has been shoved by those emissions into realms far outside her typical Holocene context. And it appears that the Winter of 2016, for the Arctic, has been the hottest such year during any period of human-based record-keeping and probably the hottest season the Arctic has experienced in at least 150,000 years.

Extreme Arctic heat February 22

(Climate Reanalyzer hits a stunning 7.06 C above the already hotter than normal 1979 to 2000 baseline for the entire region above the 66 North Latitude Line on February 22nd of 2016. It’s a very extreme temperature departure — one this particular analyst has never seen before in this record. For reference, a 3 C above baseline temperature departure for this region would be considered extraordinarily warm. What we see now is freakish, outlandish, odd, disturbing. Image source: Climate Reanalyzer.)

It’s just the most recent marker on a path toward an ever-worsening polar heat that is becoming all-the-more difficult to ignore or deny. For at current greenhouse gas levels, that polar zone is hurtling toward temperatures not seen in 15 million years. A heat pressure that will push for warming not seen in 20, 30, 50 million years or more, if a nightmarish fossil fuel burning continues.

Nothing in the recent geological past can compare to the danger we are now in the process of bringing to bear upon our world. Not the Great Flood. Not the end of the last ice age. Those were comfortable, normal cataclysms. Human beings and life on this world survived them. But the kind of geophysical changes we — meaning those of us who are forcing the rest of us to keep burning fossil fuels — are inflicting upon the Earth is something entirely new. Something far, far more deadly.

Extreme Arctic Heat Ramps Up Yet Again

At the start of 2016, we find ourselves experiencing a year during which our world is steepening its ramp-up toward this kind of catastrophic global heat. During January of 2016, the Arctic experienced its most extreme temperature departures ever recorded. February, it appears, was at least as bad. Today, daily temperature departures for the Arctic in the Climate Reanalyzer measure were a stunning +7.06 above an already hot 1979-to-2000 baseline (see graphic above).

To put this in perspective, a region larger than 30 million square kilometers or representing fully 6 percent of the Earth’s surface was more than 7 degrees Celsius hotter than average today. That’s an area more than three times larger than the United States including Alaska and Hawaii. A region of the world that includes a vast majority of the remaining frozen Northern Hemisphere land and sea ice. And since an extreme heatwave is typically defined as temperature departures at about 3 C above normal for an extended period of time over a large region — the Arctic appears to be experiencing some ridiculously unseasonable temperatures for this time of year.

80 North Temperature departures February 22 NOAA

(A seemingly unstoppable period of record warmth continues for the High Arctic on February 22nd. Readings for this zone have consistently remained in the warmest 15 percent of readings on up to record warmest readings for each day since January 1, 2016. Image source: NOAA.)

Above the 80 North Latitude line, departures were even more extreme — hitting about 13 C or about 23 F warmer than normal for the entire High Arctic surrounding the North Pole today (see above graphic). Temperatures that are more typical for late April or early May as we enter a time of year when this region of the Arctic is usually experiencing its coldest readings and sea ice extents would normally continue to build.

Unfortunately, today’s extreme heat was just an extension of amazing above average Arctic temperatures experienced there since late December. So what we are seeing is consistently severe Arctic warmth during a season that should be Winter, but that has taken on a character more similar to a typical Arctic Spring. Warmth that is now enough to have already propelled the Arctic into its warmest ever yearly temperatures when considering a count of below freezing degree days.

Arctic Degree Days Below Freezing Anomaly

(Degree Days below Freezing [or Freezing Degree Days, FDD] shows a 670 FDD departure below that seen during a typical year. If the current trend continues, the Arctic may see degree days below freezing lag by between 900 and 1,500 — knocking off about 15 to 25 percent of below freezing days from a typical Arctic year. Note that the departure line steepens rapidly after the first major warm wind event hits the Arctic during late December of 2015 — driving temperatures above freezing at the North Pole for the first time ever so late in the year. Image source: NOAA.)

Freezing degree-days (FDD) or thawing degree-days (TDD) are defined as departures of air temperature from 0 degrees Celsius. The less FDDs during an annual period, the warmer the Arctic has become. Under the current trend, the Arctic is now on track to hit between 15 and 25 percent less FDDs than it experiences during a typical year in 2016.

Looking at the above graph, what we see is an ongoing period in which Winter cold has been hollowed out by a series of warm air invasions rising up from the south. These warm wind events have tended to flow up through weaknesses in the Jet Stream that have recently begun to form over the warming Ocean zones of the Bering, Northeast Pacific, Barents, and Greenland seas. Still more recently, warm wind events have also propagated northward over Baffin Bay and Western Greenland — even shoving warm air into the ocean outlets of a typically frozen Hudson Bay.

Perhaps more starkly, we find a steepening in the rate of Freezing Degree Day loss following the freakish series of storms that drove the North Pole above Freezing during late December of 2015 — the latest during any year on record that the North Pole has experienced temperatures exceeding 0 C.

Arctic Sea Ice Declining Since February 9th

Overall, a rapid heat uptake by the world ocean system appears to be the primary current driver of extreme Arctic warming. Atmospheric heat from greenhouse gas warming swiftly transfers through the ocean surface and on into the depths. During recent decades, the world ocean system has taken in heat at a rate equal to the thermal output of between 4 and 5 Hiroshima-type bombs every second (with some individual years hitting a much higher rate of heat uptake).

Since thousands of meters of warming water insulates better than the land surface and diaphanous atmosphere, this added heat is distributed more evenly across the globe in the world ocean system. As such, ocean warming is a very efficient means of transferring heat to the Northern Hemisphere Pole in particular. The reason is that the Pole itself sits atop the warming and globally inter-connected Arctic Ocean. In addition, the warming surface waters, as noted above, provide pathways for warm, moist air invasions of the Arctic — especially during Winter.

For 2016, these kinds of heat transfers not only resulted in an extreme warming of airs over the Arctic, they have also shoved the Arctic sea ice into never-before-seen record lows for area and extent.


(NSIDC shows Arctic sea ice entering a new record low extent range from February 2 through February 21 of 2016. A peak on February 9 and decline since concordant with record warmth building throughout the Arctic begs the question — did the sea ice melt season start on February 9th? Possible — but too early to call for now. Image source: NSIDC.)

Off and on throughout January, but more consistently since early February of 2016, Arctic sea ice has continued to hit new daily record lows. For Arctic sea ice extent, the record lows entered a streak that has now been unbroken since February 2nd. By the 21st, extent measures had hit 14.165 million square kilometers in the National Snow and Ice Data Center measure. That’s about 200,000 square kilometers below the previous record low extent value for the date set during 2006.

Perhaps more ominously, the current measure appears to have fallen off by about 50,000 square kilometers from a peak set on February 9th. And with such extreme heat driving into the Arctic over recent days, it appears that this departure gap could widen somewhat over the coming week.

Overall, radiation balance conditions for the Arctic are starting to change as well. The long polar night in the Arctic is beginning to recede. Sunlight is beginning to fall at very low angles over the sea ice, providing it with another nudge toward melting. Finally, the greatly withdrawn ice has uncovered more dark ocean surfaces that will, in turn, absorb more sunlight as the Arctic Winter proceeds on toward Spring.

With sea ice declining slightly since February 9, with record warmth already in place in the Arctic, and with the sun slowly beginning to provide its own melt pressure, it appears risks are high that we see a record early start to Arctic melt season. Seven day forecasts do show high Arctic temperature departures receding a bit from today’s peak at around 6-7 C above average to between 4 and 5 C above average by the start of next week. But heat at the ice edge in the Bering, Barents, Greenland Sea and Baffin Bay are all likely to continue to apply strong pressure on sea ice extent and area totals. In addition, recent fracturing within the Beaufort has generated a number of low albedo zones that will face a wave of unseasonable warmth riding up over Alaska during the coming days which will tend to slow rates of refreeze even as Western Alaska’s waters feel the heat pressure of off and on above freezing temperatures.

So it appears we may have already begun, in early February a melt season that will last through mid-to-late September. It’s too early to make the call conclusively, but the Arctic heat and melt trends necessary to set up just such an ominous event do appear to be in place at this time. In other words, “all the devils are here…”

Major Wildfire Outbreak in Central and Western Africa as Drought, Hunger Grow More Widespread

The major news organizations haven’t picked it up yet, but there’s a massive wildfire outbreak now ongoing over Central and Western Africa. These wildfires are plainly visible in the NASA/MODIS satellite shot — covering about a 1,400 mile swath stretching from the Ivory Coast, through Ghana, Nigeria and Cameroon and on across the Central African Republic, the Congo, and Gabon.

Major Wildfire Outbreak Central Africa

(Very large wildfire outbreak in Central Africa in the February 10 LANCE-MODIS satellite shot. For reference, bottom edge of frame covers about 350 miles. Image source: LANCE MODIS.)

Smoke from these fires is extremely widespread — stretching over almost all of Western and Central Africa, blanketing parts of Southern Africa and ghosting on out over the Southern Atlantic Ocean. Together with these massive fires we have what appears to be a rather significant CO2 plume showing up in the Coperinicus monitoring system (see below). It’s a signature reminiscent of the amazing Indonesian wildfires that, during a few weeks of the Fall of 2015, matched the CO2 emission of Germany. The satellite representation of these fires is so strong that it’s difficult to believe that no news of the fires has hit the mainstream media. But, so far, there hasn’t even been a peep.

The intensely burning fires now rage across a region of Africa experiencing both severe heat and drought with temperatures hitting well over 40 C in Nigeria and over 36 C throughout the broader region today. An extreme heatwave occurring in tandem with a new kind of flash drought event that’s becoming more and more common as human fossil fuel emissions keep forcing the world into higher and higher temperatures ranges.


(The Copernicus CO2 monitor shows an intense CO2 plum issuing from very intense wildfires over Central and Western Africa on Wednesday, February 10th. Other CO2 hotspots include China, the Northeast US, Northern South America, Southeast Asia, and a region stretching from Siberia through to the Arctic. It’s worth noting that Northern Hemisphere CO2 levels now range from 400 to 414 parts per million. Image source: CAMS CO2 Monitoring.)

Central Africa is but the most recent region to feel the effects of extreme drought and related risks to food security. For through 2015 and on into early 2016, both drought and hunger grew in scope and intensity across Africa. An impact that is almost certainly related to the combined influences of a near record El Nino and global average temperatures that are now in the range of 1.1 degrees Celsius hotter those seen at the end of the 19th Century.

El Nino + Global Warming’s Impact on African Drought Risk

As a human-forced heating of the globe warms the world’s airs and waters, the rate of evaporation and precipitation intensifies. On the wet end of the spectrum, the added heat and atmospheric moisture provides more available energy for storms. But on the dry end, droughts can appear more rapidly, become more intense and, in many cases, become longer-lasting. Effects can generate entirely new weather patterns — as seen in increasing instances of heat and drought appearing over the US Southwest or the progressively more stormy conditions showing up over the North Atlantic. Or they can intensify an already prevailing pattern.

Large sections of Africa suffering from severe drought

(Large sections of Africa suffering from severe drought as of February 7th in the Africa Flood and Drought Monitor graphic above. Widespread areas in red show soil moisture levels hitting their lowest possible rating in the monitor over widespread regions during recent days.)

In the case of the latter, it appears that just such an event may be happening now across Africa. During typical strong El Nino years, heat and drought were already at risk of intensifying — particularly for regions of Southern and Eastern Africa. But now, with global temperatures 1.1 C hotter than those seen during the late 19th Century, the drought risk is amplified. Added average atmospheric heat sets base conditions in which water evaporates from the soil more rapidly — so a pattern that would typically result in drought risk becomes far more intense and dangerous.

Over the past year, intense drought has impacted widespread regions across eastern and southern Africa. Sections of South Africa experienced its lowest levels of rainfall since record-keeping began in 1904 even as widespread drought from the Horn of Africa and regions south and westward put millions at risk of a growing hunger crisis.

Hunger Crisis Spreads, Fear of Famine Grows

According to The World Food Program and a February 10 report from VICE News, the widespread and growing drought is taking its toll. Skyrocketing local food prices, mass displacement due to political instability, and failed crops due to the driest conditions in 35 to 111 years are all having an impact. Now, more than 20 million people are at risk of hunger across Africa.

In Zimbabwe, President Mugabe declared a state of emergency as more than a quarter of the 13 million population struggled to access food. Many families were reported to have gone more than a week without a meal amidst heightening concerns over potential food riots. In Somalia, more than 3.7 million people faced acute food insecurity even as 58,000 children were at risk of dying during 2016 due to lack of food. Nearly 10 million people in Sudan were reported at risk of going hungry even as 40,000 were identified as potential immediate casualties due to the growing crisis. In Ethiopia, massive livestock losses due to drought are resulting in the worst food crisis since 1984 — a year that saw an estimated 1 million die due to famine.

Food Emergency in East Africa

(A food emergency — shown in red — emerges in East Africa even as food crises erupt across Central and Southern Africa. Food emergency regions indicated in red on this map are just one level below famine. Image source: Famine Early Warning System.)

Meanwhile, according to the Famine Early Warning System, Niger, Nigeria, Chad, Yemen, Zambia, Mozambique and Madagascar all faced potential food crises through March. Risk of hunger is also compounded by a large number of displaced persons throughout Africa with East Africa alone hosting over 5.1 million refugees across South Sudan, Burundi, and Yemen.

Rain patterns are expected to shift eastward, bringing some relief to sections of the Horn of Africa even as drought is predicted to expand into the regions of Central Africa now experiencing intense wildfires.

Even a Monster El Nino Can’t Beat the Southwest Drought

For those who follow weather, it’s a rather strange and disturbing story.

A powerful Pacific Ocean storm forms about 500 miles south of the Aleutian Islands. Heavily laden with rains, strong winds, and trailing a long squall line, the system takes aim at the US West Coast. It’s a burly beast of a thing. Pumped up by an enormous bleed of moisture rising off of one of the mightiest El Ninos ever seen. An instance of extreme Equatorial heat that’s been firing off since October.

Another Pacific Storm Deflected

(Another Pacific Storm is deflected northward by increasingly persistent high pressure systems as the US Southwest swelters under unseasonable warmth. GFS climate reanalysis by Climate Reanalyzer shows this disturbing weather pattern again and again in the February forecast. In short, it doesn’t look like the California Drought is going to end anytime soon. Image source: Climate Reanalyzer.)

The towering El Nino-fed storm clouds chug east, steaming along toward what appears to be an inexorable collision with California, Oregon, and Washington. But, at the last moment, the storm slams into a heavy pile of atmospheric heat. Warm air building over the US Southwest and nearby ocean zones has shoved the upper air steering current called the Jet Stream pole-ward. The great storm is sucked up into this atmospheric train, delivering its rains along an arc from Washington State on northward.

And so the seemingly impossible has happened. A powerful El Nino’s rains and snows — usually bound directly for California, Oregon and Washington — have been diverted by a new kind of atmospheric pattern associated with climate change.

El Nino’s Rains Gone or Just Taking a Break?

Ever since late January, strong ridges have tended to develop over Western North America. By February 4th, the National Weather Service (NWS) had begun to report on the pattern — describing  it as El Nino taking a 5-10 day break. But the ‘break’ had already begun to show up on January 26th — about ten days prior to the February 4 NWS announcement. And now, on February 10, we’ve seen two full weeks of warm, dry weather settling in over California and the US Southwest. Meanwhile, long range model forecasts indicate that the ‘break’ from El Nino conditions will continue through at least February 16th.

Upper 60s to upper 80s California and Arizona

(Temperatures in the upper 60s to upper 80s is predicted for a large sections of California and Arizona on Tuesday, February 16th. It’s the kind of hot, dry air that brings back memories of recent years when formations of strong, ridiculously resilient ridges pushed California into one of its worst drought episodes on record. Image source: Climate Reanalyzer.)

It’s all just terrible timing. First, California snow packs during December and January began to recover due to strong, El Nino associated, storm systems barreling in. However, now during what should be the peak of the Southwestern rainy season, we have what could be a month long pause in storms hitting the region. It’s as if the rainy season is being hollowed out. And not just any rainy season — a strong El Nino rainy season which should have been far, far rainier than most.

Last week, Climate Central and Peter Gleick — a climate expert at Pacific Institue — made the following warning:

seven days of sustained warmth could melt as much as 30 percent of California’s snowpack. The hot, dry weather is exactly what baked in exceptional drought in California over the past four years. Some signs indicate the heat is driven in large part by climate change, but the role of the ridiculously resilient ridge is still an area of active investigation.

Well, by tomorrow seven days will have come and gone. But the end to the anomalous warm, dry spell is still nowhere in sight.

California Drought Really Hasn’t Budged

Meanwhile, a four-year-long California drought appears to be making a strong run at year five. In fact, if you look at the US Drought Monitor, you’ll find that a large swath of the West is currently suffering under moderate to exceptional drought conditions.

West Still Suffering From Drought

(Severe Drought remains in place over the US West. El Nino appears to have lost at least some of its ability to deliver heavy rains as an intensifying regime of human-forced warming pushes typical weather patterns further and further off-kilter. All bad news for an area that has been suffering from one severe drought after another since the early 2000s. Image source: Drought Monitor.)

Quite frankly, it’s insane that we’re still seeing these conditions during a monster El Nino. These droughts should be rolling back as the storm track intensifies and hurls severe weather at the US West Coast. But that’s not what’s happening. At least not consistently. Instead, we keep getting these extreme ridge patterns in the Jet Stream over western North America. We keep getting these very warm, very dry spells of weather during the wet season. And now, we have California Snowpack melting away in February of all times.

A Ridge-Trough Pattern That’s All-Too Likely Related To A Human-Forced Warming of the Arctic

The fact that these weather patterns emerged after the warmest January and lowest sea ice extents on record for the Arctic is a point that should not be missed by weather and climate analysts. It appears that what we are seeing is yet more evidence that polar amplification is driving a consistent high amplitude bulge in the Jet Stream over Western North America together with severe periods of warmth, dryness and snowpack melt during Winter. The hot side of a dipole pattern that is also setting up more extreme storm potentials as cold air is driven out of the Arctic along a deep trough over the Eastern US, slams into a record hot Gulf Stream, and then sets off a series of atmospheric bombs along a storm track running all the way across the North Atlantic and into Western Europe. Yet more evidence that what happens in the Arctic doesn’t stay in the Arctic.

Atmospheric CO2 Rocketed to 405.6 ppm Yesterday — A Level not Seen in 15 Million Years

As CO2 levels hit a new record global high of 405.66 ppm yesterday, I couldn’t help but think that HG Wells could not have imagined a more perilous mechanism for exploring the world’s past.

For when it comes to testing the range of new climate extremes, the present mass burning of fossil fuels is like stepping into a dark time machine. As all that carbon hits the airs and waters, the climate dial spins backward through hundreds of thousands and millions of years. Speeding us on toward the hothouse extinction eras of Earth’s deep history. Now, not only is it driving us on through extreme weather and temperature events not seen in 100, 1,000, 5,000 or even 10,000 years, it is also propelling us toward climate states that haven’t occurred on Earth for ages and ages.


Ever since 1990, the world has experienced atmospheric CO2 levels in a range that hasn’t been seen since the Pliocene geological epoch. A period of time 2.6 – 5.3 million years ago hosting carbon dioxide levels ranging from 350 to 405 parts per million and global average temperatures that were 2-3 degrees Celsius hotter than 1880s levels. Overall, global sea levels towered about 80 feet higher than those humankind has grown accustomed to.

Annual mean CO2 Growth Rate

(Never has the Earth seen a CO2 build-up so rapid as the one produced by the human fossil fuel energy era. Rates of CO2 increase just keep ramping higher ever as the world’s climate sinks appear to be filling up. In this context, 2015 saw the swiftest pace of CO2 rise yet. Warming ocean surface waters can’t absorb as much CO2 as cooler oceans. And a record hot ocean during 2015 contributed to this extreme atmospheric CO2 accumulation. For the whole of the past year, CO2 built up in the atmosphere at a rate of 3.2 parts per million per annum. That’s well above the already raging pace of 2 parts per million average annual accumulation during the decade of the 2000s. Image source: NOAA ESRL.)

If global atmospheric CO2 levels had stabilized in this range, it’s likely that we would have eventually seen climates, temperatures, and sea levels that became more and more like those experienced 2-5 million years ago. A process that would have likely taken centuries to reach a final, far warmer climate state. One in which little to no ice remained upon Greenland or West Antarctica, and one hosting a substantial retreat of coastlines.

From 1990 through 2015, that was our climate context. The new world that was steadily settling into place. One that would eventually assert itself unless atmospheric CO2 levels were somehow drawn down to below 350 parts per million. It was kind of a big deal. Unfortunately, few experts really talked about it.

Exiting the Pliocene

But starting in 2015 and continuing on into 2016 the fossil fuel burning time machine again cranked us back toward hotter, more dangerous times. For during the past two years we began to exceed the maximum CO2 threshold of the Pliocene and we started to enter CO2 ranges that were more typical to those of the Middle Miocene climate epoch of 15 to 17 million years ago.


Rocketing on past the Pliocene

(Rocketing on past the Pliocene. On February 4 of 2016, a record daily atmospheric CO2 level of 405.66 was recorded at the Mauna Loa Observatory. The Earth hasn’t experienced CO2 levels this high in 15-17 million years. Image source: NOAA ESRL.)

By late April of 2015, as CO2 approached its typical May high point, daily readings had hit a range of 404.9 parts per million — propelling us toward the outside boundary of the Pliocene climate context. For a brief period of 9 months, CO2 retreated back from the Pliocene boundary as spring and summer-time plants in the Northern Hemisphere respired. However, average atmospheric CO2 levels were still ramping higher as a rampant burning of fossil fuels around the world continued. By yesterday, February 4, 2016, daily CO2 levels at the Mauna Loa Observatory had rocketed to 405.66 parts per million. A level well outside the upper range for the Pliocene climate epoch. One more typical for periods seen during the Miocene of 15-17 million years ago.

Entering the Middle Miocene

Unfortunately, this daily Februay peak at 405.66 parts per million is not the end to the current year’s ramp up. Typical atmospheric peaks occur during May. And this year, we are likely to see atmospheric levels hit near a range of 407-409 (estimate revised in March of 2016) parts per million in the weekly and monthly averages over the next few months. Such a range thrusts us solidly out of the Pliocene climate context and well into that of the Miocene.

Though the Middle Miocene was not a hothouse extinction climate, it was one much more foreign to humankind. Back then, only the great apes existed. Our most ancient ancestor, Australopithecus, was still at least 9 million years in the future. It’s fair to say that no human being, or even our closer offshoot relatives, have ever breathed air with the composition that is now entering our lungs. Never lived under the oppressive and intensifying dome of such a great global atmospheric heat forcing.


(We said farewell to the Holocene climate context when CO2 levels rose above 280 parts per million back during the 19th Century. By around 1990, we had begun to enter the Pliocene context, a period occurring 2-5 million years ago. As of 2015, we had begun to exit the Pliocene climate context and enter the Middle Miocene. If current rates of fossil fuel burning or business as usual rates of fossil fuel build-up continue, we will be entering the Ogliocene climate context in about 25 to 50 years. Image source: NOAA ESRL.)

We are now entering a period in which atmospheres are more similar to those seen during the Middle Miocene Climate Optimum — the last time CO2 measures exceeded a threshold of roughly 405 parts per million (see here and here).

The Middle Miocene Climate Optimum of 15-17 million years ago was a radically different world. It hosted an atmosphere in which carbon dioxide levels varied wildly from 300 parts per million to 500 parts per million. Temperatures were between 3 to 5 degrees Celsius hotter than the 19th Century. And sea levels were about 120 to 190 feet higher. During this period, the world was still cooling down from the heat of the Paleocene and Eocene epochs. Carbon was being sequestered. And it was the first time the world broke significantly below a 500 part per million CO2 plateau that had been established during the Oligocene 24 to 33 million years ago.

If CO2 levels remain in this range, these are the temperatures, sea levels, and climate conditions we will transition to and ultimately experience. But time, and fossil fuel burning, is not on our side. For under business as usual fossil fuel burning rates of increase, we could hit the Oligocene threshold within as little as 25-30 years. And even if the current rate of increase were maintained, the Oligocene boundary sits about 5 decades away.

Rapid Acceleration in Sea Level Rise — From 2009 Through October 2015, Global Oceans Have Risen by 5 Millimeters Per Year

The evidence that a human-forced warming of the globe is hitting a much higher gear in terms of both added heat and ramping impacts just keeps streaming on in. Today, an update in the satellite monitor tracking global sea level rise provides yet one more ominous marker. The world’s oceans are rising at an unprecedented rate not seen since the end of the last Ice Age. A rate that appears to be rapidly accelerating.

Greenland Melt Zachariae Isstrom

(Surface melt visible across the Zachariae Isstrom Glacier in Greenland on July 20th of 2015. Melt like that occurring on this glacier has become more and more widespread over Antarctica and Greenland. It’s an ongoing heat accumulation in the world’s great ice mountains that is contributing to increasing melt water outflows into the rising world ocean system. Image source: LANCE MODIS.)

It’s a tough bit of evidence that the world is swiftly accumulating heat. For aside from atmospheric temperature readings, the rate of sea level rise is probably the best marker for how fast the world is warming. It’s a sign of heat build-up that’s thermally expanding the ocean. And, far more ominously, it’s a sign that the great glaciers of the world are starting to accumulate enough heat to go into a more and more widespread melt and destabilization.

Ocean Rise Begins with Ramp-up in CO2 Emissions

Ever since the Holocene climate era began about 10,000 years ago, ocean levels and shorelines have remained remarkably stable. At the close of the 19th Century, and in conjunction with a build-up of heat-trapping gasses in the atmosphere through the extraction and burning of fossil fuels, sea levels began a rise that would start to mark a departure from the stable coastlines human civilizations had enjoyed for so long.


(Global sea level rise has ramped higher and higher — an upward curve that follows increasing volumes of CO2 in the atmosphere and rising global temperatures. Image source: Dr. James Hansen.)

At first the rise in global waters, driven by a then slow accumulation of heat in the world ocean system, was slight and gradual. Beginning in 1870, and continuing on through 1925, sea levels across the world increased by about 0.8 millimeters per year. The increase was likely driven by heat accumulating in the atmosphere and then transferring to the surface waters of the oceans. From 1870 through 1925, atmospheric carbon dioxide levels had increased from around 280 parts per million to 305 parts per million — into a range about 25 parts per million above the typical interglacial peak CO2 level of the last 2 million years. A volume of heat trapping gasses that began to slowly upset the Holocene’s relative stability.

If scientists and researchers at the time were paying closer attention, they would have noted this mild but consistent increase in the height of global surface waters as the first hint that the human emission of greenhouse gasses was starting to alter the Earth environment. Sadly, it took many more decades to begin to understand the profound changes that were starting to take place.

The First Acceleration — 1925 to 1992

While climate science was still in its infancy during 1925, a human forced warming of the globe was starting to kick into higher gear. A signal of atmospheric warming since the 1880s was beginning to develop. Though unclear, it was becoming apparent that the airs of the world were building up heat. But the waters of the world were providing a strong signal that the Earth was accumulating that heat more and more rapidly.

Sea level rise, at that time driven by thermal expansion and by a later small but growing contribution from glacial melt, took its first leap higher. And from 1925 through 1992, the average rate of sea level rise more than doubled to 1.9 millimeters per year. It was a sign that the Earth was warming more and more rapidly and that the heat was showing up in still more thermal expansion of the world’s waters.

The Keeling Curve

(Globally, CO2 began to increase in the atmosphere starting with the widespread burning of coal in England during the 17th and 18th Century. As new fossil fuels like natural gas and oil were added to the mix and as fossil fuel based burning greatly expanded during the 19th, 20th, and 21st Centuries, concentrations of this key greenhouse gas sky-rocketed. By the decade of the 2010s, the rate of atmospheric greenhouse gas accumulation was about 6 times faster than at any time in the geological record. A human emission that, if it continues for just a blink in geological timescales, is the equivalent to multiple clathrate guns firing off at the same time. Image source: The Keeling Curve.)

During the same period, atmospheric greenhouse gasses increased from 305 parts per million in 1925 to around 350 parts per million (entering the bottom range of the Pliocene 2-5 million years ago) by 1992. This jump by 45 parts per million in just 67 years pushed the Earth’s climate well outside the range of past interglacials — exceeding the previous peak of 280 parts per million CO2 by more than 70 parts per million overall. Atmospheric temperatures, by 1992, had also increased into a range about 0.5 C above 1880s values.

We had started to enter a period where the context of the human-driven warming (primarily enforced by a monopolization of energy markets by fossil fuels) was being pushed far outside the range of the Holocene and into time periods tens of thousands to hundreds of thousands of years in the geological past. The Earth System, in other words, was entering a period of increasingly dangerous imbalance.

The Second Acceleration 1992 to 2009

During the 17 years from 1992 through 2009, atmospheric carbon dioxide levels rose by 40 parts per million to about 390 parts per million in total. That’s a rate of accumulation nearly four times faster than the entire period from 1925 through 1992. An accumulation that by 2009 had pushed the world into a climate context more similar to the warmest periods of the Pliocene of 2-5 million years ago, than of the geological epoch in which human civilization emerged and thrived. For the Holocene was then starting to look like some fond memory fading off into an increasingly murky and smoke-filled far horizon.

Rate of ocean heat uptake has doubled since 1997

(The amount of heat contained in the world ocean system has doubled since 1997. This raging ocean heat uptake has been fueled by a heat accumulation at the top of the atmosphere that is now equivalent to lighting off 5 hiroshima type bombs on the surface of the Earth every single second of every single day. 90-95 percent of this heat goes into the world ocean system. Image source: Dr PJ Gleckler — Industrial Era Ocean Heat Uptake Doubles. See Also: Skeptical Science.)

Rates of sea level rise again increased — hitting a ramp up to around 3 millimeters per year. More ominously, scientific studies were beginning to indicate that the Greenland Ice Sheet and West Antarctica were starting to significantly contribute to the rising waters. The great glaciers were showing their first signs of a mass seaward movement called a Heinrich Event. And with the world hitting 0.8 degrees Celsius above 1880s temperature values and rising, such an event was starting to look more and more likely.

Sea Level Rise at 5 Millimeters Per Year Since 2009

Now, by early 2016, with the world at 1.1 C warmer than 1880s averages and with CO2 levels likely to peak at around 407 parts per million this year, it appears that rates of sea level rise have again jumped markedly higher. For according to satellite altimetry data from AVISO, global sea levels rose by 36 millimeters from the end of 2009 through October of 2015. That’s an annual rate of around 5 millimeters per year and one far above the longer term range of 3.1 mm per year established from 1992 through 2012.

Sea level rise AVISO

(Global sea level rise as measured by satellite altimetry hits a noticeably higher ramp from 2009 through late 2015. Image source: AVISO.)

We can clearly see the departure from the trend line starting post 2011 in the above graph. And if we were to cherry pick that particular departure zone, the rate from trough-to-peak would be 7 millimeters per year. However, since a La Nina occurred during 2011-2012 and a record strong El Nino is occurring now, that particular trend line is probably a bit exaggerated. The reason being that La Nina tends to dampen rates of sea level rise through variable cooling and El Nino tends to spike rates of sea level rise as world surface waters warm during such events.

However, even when correcting for La Nina and El Nino variation, it appears that sea level rise since 2009 is tracking in a range of 4 to 5 millimeters each year — which is yet another significant departure from the trend. A rate that, if it were to further solidify, would be 5 to 6 times faster than initial rates of sea level rise at the start of the 20th Century or two and a half times faster than the sea level rise rates from 1925 through 1992.

(Open water and no snow in Southern Greenland on February 2 of 2016. Zero sea ice and no snow in southern Greenland during Winter is a strong sign that the island is falling deeper and deeper into the grips of a severe warming event. Image source: Greenland Today.)

Spiking rates of heat accumulation and related thermal expansion of the world’s oceans is likely playing a part in the current increase. But, all-too-likely, the numerous destabilized glaciers now rushing seaward — which in total contain at least enough water to raise seas by 15-20 feet — are also starting to add greater and great contributions. And, unfortunately, with global temperatures now pushing into a very dangerous range between 1 and 2 degrees Celsius above 1880s averages, we are likely to see more and more of these glaciers go into a rapid seaward plunge. It looks like we’ve already locked in a ramping rate of sea level rise for decades to come and at least 15-20 feet long term. But that pales in comparison to what happens if we keep burning fossil fuels.

Sea Ice Death Spiral Continues — Start of 2016 Sees Arctic Ocean Ice Hitting New Record Lows

In January, Arctic sea ice extent hit a new record average low for the month. Meanwhile, during the first days of February, both Arctic sea ice extent and area hit new daily record lows even as global sea ice area also entered the second lowest range ever recorded. And so it seems that the sea ice death spiral of a record warm world continues.

January lowest sea ice on record

(According to the National Snow and Ice Data Center, Arctic sea ice extent averages were the lowest on record for the month of January since at least 1979. The new low beats out 2011, continuing an ongoing decadal January decline of about 420,000 square kilometers every ten years. Image souce: NSIDC.)

But before we go more into the new spate of record low Arctic and global sea ice measures, it’s important to consider the context — our world has not seen the current level of heat forcing from greenhouse gasses (CO2 + methane + NOx + other greenhouse gasses) in the atmosphere since about 15 million years ago. It’s an unprecedented amount of hothouse potential that is having equally unprecedented results.

Unprecedented Volume of Heat Trapping Gasses Drives Raging Atmospheric and Ocean Warming

About 50 billion tons of CO2 equivalent from all those greenhouse gasses hit the Earth’s atmosphere each year these days. In vast part driven by industrial fossil fuel burning and extraction, this unconscionable, monstrous, and difficult-to-imagine accumulation of heat-trapping vapors is pushing the world to warm up at an unprecedented rate. A pace that is now at least 20 times faster than the widespread warming that occurred at the end of the last ice age.

Temperatures above 80 North

(It’s likely been a record warm start of the year for the Arctic above the 80 degree North Latitude Line. Temperatures in that high Arctic region have tended well outside the 2 standard deviation range and have hit above the record line on numerous occasions. Image source: NSIDC.)

Back then, it took about 2,500 years for the Earth’s atmosphere to heat by 1 degree Celsius for a total of a 4 C temperature increase over 10,000 years. By just this past year, in 2015, fossil fuel burning had managed to do more in 135 years than what an Earth System rising up out of an ice age did in all of two and one half millenia. For 2015 hit a new record high of about 1.1 C above 1880s averages in all the major global temperature monitors (NASA, NOAA, JMA, UK MET Office). It’s amazing, crazy, terrifying to think about. The end of the last glacial period was a great upheaval that violently re-shaped our world. And fossil fuel industry is running a similar, if much more dangerous, geological process in fast forward by pumping out heat trapping gasses at a rate at least six times faster than anything seen in all of Earth’s history.

Yet as amazing as the current rate of atmospheric warming is, it’s just the thin lens through which a vast amount of heat is transferring into the world’s ocean systems. In fact, according to Peter Gleckler, an oceanographer at the Lawrence Livermore National Laboratory “Ninety, perhaps 95 percent of the accumulated heat is in the oceans.”

Arctic Sea Ice Concentration January

(What was possibly the warmest January on record for the Arctic contributed to major sea ice losses in almost all of the major ice formation basins. Image source: NSIDC.)

And all that extra heat doesn’t just sit there. It goes to work transforming water to water vapor — shoving atmospheric moisture content 7 percent higher for each degree Celsius of warming even as it amps up the rate at which water evaporates from the Earth’s surface or falls down in the form of precipitation. Perhaps still more ominously, this heat goes to work melting the great white ice coverings it comes into contact with at the shoreline and upon the ocean surface.

Arctic Sea Ice Hits New Record Lows For January Through Early February

For 2016, that heat has led to new record lows in Arctic sea ice extent and area even as it has pushed global sea ice coverage within striking distance of a scant range never before seen in the whole of the modern era. New record daily lows for sea ice extent — now an almost annual occurrence for at least some time during the calendar year — are now also being breached.

Arctic Sea ice area new record lows

(Arctic sea ice area explores new record low territory on January 29 through 31 of 2016. Image source: Cryosphere Today.)

In the major monitors, Arctic sea ice extent hit a new record low average for the month of January, 2016. This average included a number of record daily lows early in the month even as the entire monitor held within 1st to 3rd lowest on record for each day throughout January. Record daily lows were again breached in the NSIDC measure on January 29th. A streak that continued on through February 1st with totals hitting 13.911 million square kilometers for the day. That’s 119,000 square kilometers below the previous record daily low for February 1 set in 2011 at 14.030 million square kilometers or a region of ice lost below the previous minimum extent slightly larger than the State of Virginia.

Arctic sea ice area as recorded by Cryosphere Today (see graphic above) followed a similar record low range through the end of January. By January 31st, the most recent date in the measure, Arctic sea ice area had hit 12.27 million square kilometers or about 61,000 square kilometers below the previous record daily low for sea ice area set during 2006.


(A very warm Arctic during January of 2016 likely contributed to shoving the global sea ice area measure into striking distance of new record lows by early February. Image source: Pogoda i Klimat. Data Source: Cryosphere Today.)

Also disturbing is the fact that global sea ice area — which has shown consistent losses over time — has also now come within striking distance of new record lows. The Cryosphere Today monitor now shows global sea ice area in the range of 14.5 million square kilometers or just above previous record lows set during 2006 for this time of year.

Conditions In Context — Amazing Sea Surface Temperature Anomalies, Major Winter Warm-ups Hit Sea Ice Hard

Arctic sea ice area negative anomaly is now in the range of -1.23 million square kilometers. With Antarctic sea ice at around 200,000 square kilometers below average, it’s pretty clear that the bulk of current global sea ice losses are now ongoing in the Arctic.

Warm ocean waters, especially in the Barents Sea and the Greenland Strait are likely major contributors to record low sea ice extents during recent weeks. These sea surface temperatures now show between 1 and an amazing 8 C above average reading in the NOAA sea surface temperature anomaly map below.

NOAA Sea surface temperature anomalies

(Sea surface temperatures are in the range of 4-8 degrees Celsius or 7-14 degrees Fahrenheit above average near sections of sea ice in the Northern Barents Sea. These very warm sea surfaces continue to suppress refreeze and provide melt pressure on into early February. Image source: NOAA.)

Such amazingly warm waters likely helped contribute to major atmospheric warming events in the high north over the past two months including one above freezing event at the North Pole during late December and another near freezing event for the same region during late January, likely added to the overall melt pressure. The very warm water in the Barents likely helped to enable the observed warm air slots that formed north of Svalbard and on toward the North Pole on numerous occasions.

Over the next seven days, Arctic air temperatures are expected to range about 1 C above average — as opposed to the 2-3 C above average range seen during the past month. This slight cooling may allow for a more rapid freezing of some regions including the Sea of Okhotsk. But overall warm waters and airs along the sea ice edge in the Bering and Barents should continue to suppress major ice formation there. By the second week of February, risk increases that high amplitude Jet Stream waves will deliver another burst of warm air to the far Northern Latitudes, potentially continuing the trend of extreme above average atmospheric temperatures in the region of the Arctic Ocean during 2016.
