It’s the stuff that climate disaster movies are made of. But the events are all too real — happening now and not part of some dramatized script played out on the silver screen.
Signs abound that global ocean circulation is being profoundly altered by human-forced climate change. A pool of cold water has developed in the North Atlantic. England is getting slammed by anomalous winter-type rains and gales in August. And sea surface heights off the US East Coast are more than 30 centimeters (one foot) above the 1979 to 2015 average.
(Global sea surface height anomalies off the US East Coast are more than a foot (30 cm) above the 1979 to 2015 average. A clear sign that the Gulf Stream is slowing down, perhaps by as much as 15-30 percent. Complete shut down of the Gulf Stream, though unlikely without extremely large melt outflows from Greenland, would result in a very dangerous 1 meter sea level rise. An impact that is primarily driven by ocean current change. Sea level rise by thermal expansion and glacial melt would, necessarily, pile on top of this bulge of backed up waters.

World Ocean Heartbeat Fading
This past March, after observations of rising sea levels off the US East Coast, extreme positive sea surface temperature anomalies in the same region, and a critical slowing down of North Atlantic over-turning recorded throughout the 20th Century, Professor Stefan Rahmstorf published this earth-shattering paper in the scientific journal Nature.
The paper meticulously recorded a slow-down of bottom water formation in a region of the Atlantic Ocean south of Greenland. The period studied included all of the 20th Century and the first one and one half decades of the 21st Century. Rahmstorf concluded that Greenland ice sheet melt — starting around 1900 and spiking after 1975 — was having a profound impact. Cold, fresh water issuing out from Greenland was cutting off the flow of heavier, salty water transported northward by the Gulf Stream. It was preventing larger portions of that water from sinking. And it was slowing down the Gulf Stream together with a host of other ocean circulation driving currents.
A system vital to both the life and health of the world ocean and global weather stability was entering an arrest. In other words, the world ocean heartbeat was fading.
The Gulf Stream Train Wreck
Since the publication of Rahmstorf’s paper, evidence of a bottom water formation interruption and a subsequent Gulf Stream train wreck continued to pile up. Sea surface temperatures off the US East Coast, during summer time spiked to as high as 85 Fahrenheit (29.3 C) off the coasts of New York and New Jersey. And regions off Nantucket hit as high as 80 degrees Fahrenheit (26 C). That’s between 7-10 F (4-6 C) hotter than average for an already typically warm Gulf Stream.
(Left frame image shows Gulf Stream waters spiking to 29.3 C or 85 F off New York and New Jersey. Temperatures in the range of 7-10 F [4-6 C] above average. Right frame image shows cool pool development in the typical bottom water formation zone between Greenland, England and Newfoundland. Combined with the ocean current overlay, which shows widespread meandering, this hot south, cold north ocean surface dipole is an indication that the Gulf Stream is slowing down and that bottom water formation is weakening. Image source: Earth Nullschool.)
Further north, the opposite is happening. In the region east of the Grand Banks where the Gulf Stream currents typically flow strongly, there’s only a weak, meandering, confluence. The Gulf Stream appears to have hit a barrier. It has bottled up off the Northeastern US Coast. And it appears reluctant or unable to flow past mid-ocean.
As a result, a broad zone between England, the Southeastern Coast of Greenland and Newfoundland lack the warm, salty inflow of a strong Gulf Stream. Sea surface temperatures range from 2-7 F (1 to 4 C) below average. The northward progress of heat from the Gulf Stream is tapering off. And this cut off of heat flow from Equator to mid latitudes shows more and more as the development of an anomalous cool pool continues throughout.
Taking in the entire North Atlantic, what we see is a weather-destabilizing hot-cold dipole. The warm waters are backed up off the US East Coast. This is evidenced by both the very warm sea surface temperatures and by an extreme increase in sea surface heights by 1 foot over a broad region. And to the north, we have the climate change signature cool pool.
Anomalous Storms Strike England During Summer
This Gulf Stream train wreck and related cool pool development has already done a bit of a number on UK weather this summer. A series of gales and heavy rainstorms have slammed into the UK Coast — bringing heavy seas and torrential rains. One months worth of rainfall fell over parts of the UK during the past week alone. And with more storms on the way it appears that August of 2015 may be the wettest ever recorded.
It’s a changed climate state that Dr. James Hansen warned of in a recent paper. One that means more powerful storms for the North Atlantic as the Greenland Ice Sheet spews out greater and greater volumes of water and ice. Ever since 2012, we’ve seen a tendency for these kinds of anomalously powerful storms. And more rough weather is certainly on the way.
(During the winter of 2013 and 2014, storms reshaped the coastlines of the British Isles. But this was just the start. For the North Atlantic is now in the process of firing up an age of storms. Image source: AGU.)
The Fall forecast is calling for the strong gales that we’ve already seen to continue to intensify through at least October and November. Strong storms that will draw energy by the high differences in sea surface temperatures in the North Atlantic, but also, possibly, from an El Nino-amplified storm track causing powerful troughs to begin to dig in off the US East Coast. A situation that could set up a kind of trans-Atlantic storm firing line.
The long term forecast, however, is even worse. With Greenland just beginning to shed more and more of its ice, the cool pool off England will tend to intensify even as the hot pool off the US East Coast and within the Gulf of Mexico heightens. A screaming, storm-generating temperature differential that such melt will worsen as the decades wear on and if human fossil fuel burning continues to add more heat fuel to this already developing dangerous situation.

Ah, more abandoned cars stories. That and the term ‘water rescue’ have been all too common lately.
I commented on another thread about this — it appears mainstream media is more interested about bookies bets on whether or not August will be the UK’s wettest than they are in the wet weather’s underlying causes.
Hope you’re hanging in there and have the hatches ready for battening this Fall and Winter, my friend.

/ August 26, 2015Thanks for sharing that local news Spike, as an expat now residing in the Southern Hemisphere, I like to keep track on what is happening back in the U.K. I am approaching 70 years old and can recognize the abrupt changes that are now happening. I worry that younger folk will accept this as the norm, as they will have grown up in these times of change.

Jeremy
/ August 27, 2015While I accept the premise that this is one of the worst summers in the UK, ever, and the cause, for the majority of the UK population this is just another bad summer not hugely outside of the expected norms. Last years summer was generally nice and warm. Most of us have experience of bad summers, August 1978, springs to my mind, and while there has been wet and horrible weather around when the sun does come out it can seem quite reasonable.
Most of the population spends the day in work, in doors and travel around in cars and then spend our days in houses generally not designed for outdoors living. We just do not experience weather to the same degree as past generations and this in part makes it more difficult for people to accept that weather/climate is changing and is likely to change further. Most people are satisfied by the weather forcast explanation of “it is caused by the jet stream” and are not bothered to ask why is the jet stream behaving so oddly. If the media and forcasts do not explain the cause then the politicians and business men are left off the hook and free to ruin the future. I can gently explain a possible cause to friends and colleagues but while it may get them to think about the possible causes it generally does not lead to a deeper conversation.
A big part of the problem is a politically emasulated BBC (under constant attack since the Bush-Blair Iraq war), a Met Office forced to act commercially (they have just lost the BBC contract) and media reacting to advertising pressure. The result is no public debate about climate change in the UK at the present time despite the Paris conference rolling up.
P.S. Robert drop the reference to England, UK, Britain, British Isles or Britain & Ireland would be better and more inclusive, it would also save my teeth from grinding!
robertscribbler

robertscribbler
/ August 26, 2015I think the nor-easters we see this winter will put the ones we saw last winter to shame. The firing line appears to be setting up a bit further south, though. Looks like the Mid Atlantic through Florida and the Gulf states are set for some very severe weather.
Griffin
/ August 27, 2015First off, Robert, great post!!
Second, here is a link to a webcam at Coast Guard Beach in Eastham, Cape Cod, Massachusetts. This is the heart of the beautiful Cape Cod National Seashore. The beach there is legendary. Take a look at the cam at any time of day, high or low tide. It is easy to see that the sea level has risen. There is but a tiny sliver of beach left there. There is nothing on the cam to suggest that this is one of the finest beaches in the country. I had long tried to blame it on winter erosion, but not any more. It is plainly obvious to me now. http://www.morebeach.com/cape-cod-beach-cams/coast-guard-beach
robertscribbler
/ August 27, 2015Took a look at that webcam. I think this scene — a swelling ocean taking over the beach area and running against dunes or seawall — is a sadly common one. My hometown, Virginia Beach spends millions every year to pump sand onto the shore. And when my family goes to the Carolinas for vacation in the Fall, You can’t walk 3 blocks without running into a vacation home that’s being washed out by the ocean.
godraz
/ August 27, 2015As an outer Cape Cod, Wellfleet MA resident (33 years now), and before that a summer vacationer since birth, I can attest to the more severe Atlantic beach and coastal dune whittling now occurring.
Winter storm erosion has always been a fact of life along the outer beaches, but the recent sea level rise has exacerbated this loss. While further along into North Truro & Provincetown some areas have not lost as much (and even gained some) due to the sand washed along from places like Coast Guard beach. Yet now, with sea level rise even these small gains will be swept away. More dramatically it won’t be long before the break through at Ballston Beach in Truro into the marsh at the head of the Pamet River divides the Cape with a complete oceanic inlet from the Atlantic to the Cape Cod Bay.
More noticeable to me is how the vast low tidal flats that used to exist on the bayside of the Cape when I was a child are just no longer there! And the Bay beaches are narrower too at high tide. Eventually the loss of homes along the Atlantic side that has been an ongoing fact will eventually eat away at the multi-million dollar homes perched on the bayside as well.
Thankfully, for now, I’m situated well away from the coast and at a 50 foot elevation. But in the long run, with the kind of sea level rises already potentially baked into our cake, a lot of Cape Cod is doomed to being swamped and swept away. Unfortunately the level of awareness that these sorts of abrupt changes in sea levels and climatically altered storms to come and the untold damage they will do is practically non-existent. The number of happy motoring vacationers crowding the Cape this summer may end up being another banner year.
One final anecdote. A lobsterman I spoke with says his catch is down this year after several years of good ones, and I mentioned how the lobsters are apparently trying to move north into the cooler waters they prefer. None the less, he is building a new diesel fueled boat to add to his fleet. So it goes in crazy land.
Ed-M
/ August 28, 2015I grew up in Scituate and have been going back to visit a few times in the past year due to family reasons. The high water mark at Wells Rock on Minot Beach appears to be about a foot to a foot-and-a-half higher than I remember it to be in the 1970s.

Thanks for another fine update Robert. This development indicates the abrupt climate change that many thought would never happen. Now it seems every day there are more signs that we’ve passed a tipping point and things are accelerating and out of control.
robindatta
/ August 26, 2015There may quite possibly be persons alive today who will see New York City and other coastal metropolitan areas abandoned within their lifetimes due to 3 to 4 metres of sea level rise.
robertscribbler
/ August 26, 2015I’m sorry to say that it’s likely we’ll see some of these areas abandoned (even if SLR doesn’t hit 3-4 meters so soon). My wife and I love the beach, as so many of us do. But I refuse to hold property there now and have been urging my parents and grandparents to leave. It’s sad. Such a beautiful place. But now ever more dangerous.
PlazaRed
/ August 26, 2015I would think that with the storm surges, sea expansions, sea level rise caused by lower drag from the Gulf Stream plus general background fear, will bring about a lot of changes not only in New York but all along the eastern seaboard.
I’m a pensioner and I plan on probably seeing significant changes in the next few years, let alone decades.
Parts of New York are quite a few meters above sea level but certainly Queens and the JFK airport are going to get a trifle more than damp.
Eric Thurston
/ August 27, 2015Sigh… mentioning being a pensioner is close to home for me. I was looking forward to a retirement where I could make nice things in my woodworking shop, grow my garden and write curmudgeonly letters to the local newspaper editor.
I’m several years into retirement now at age 67, but things are not likely to get better. The smoke from wildfires has been worse every year, along with everything else related to climate change and general environmental degradation. At least I’m not near the coast with the worries attached to SLR, algal blooms, and generally having to watch the ocean dying. It’s bad enough just having to watch my particular part of the planet dying. Have to find strength somehow to deal with the coming storms.
robertscribbler
/ August 27, 2015The west has had a particularly rough few years. It seems to me that, from your region at least, concern is on the rise.
Spike
/ August 26, 2015Good to see Gavin Schmidt calling attention to paleo record for sea level/ temp relationship to NASA colleagues
Scientific reticence and sea level rise indeed.
robertscribbler
/ August 26, 20151 foot? I suppose they’re only looking at the last Century. Trouble is, glaciers tend to destabilize more rapidly outside the 1 C comfort zone. We’re pushing that now.
Also, if you go to 6 C in paleoclimate you get 40 feet per degree C. SLR response to warming appears to be asymptotic. Slower in the closer to ‘normalized’ ranges. More rapid the further you stray.
Temp itself is not the only variable worth looking at. Energy imbalance at the top of the atmosphere implies a rate of heat uptake by oceans that provides melt pressure on sea facing glaciers and ice shelves.
Griffin
/ August 27, 2015That was an interesting exchange on Twitter. The great Kees van der Leun was calling them out for being far too conservative as well. A very misleading day for NASA’s Sea Level Rise account.
John Christian Lønningdal
/ August 27, 2015We had this NASA news in Norwegian media too, way too conservative imo.
And naturally at least one media outlet had front page denier nonsense from a retiring physicist at a university here in Norway giving a lecture about the “climate panel” not looking at the sun and other factors for climate change. Its always a classic case of denial when they treat IPCC as the source of AGW information as if it was them who came to this conclusion. I wonder how people like that can even be teachers at a university?
robertscribbler
/ August 27, 2015Replying to both Griff and John —
It’s a false frame. We should be viewing many of these folks at NASA and IPCC as the real skeptics — as skepticism is naturally part of the science. The denialism is industry and special interest funded. And should be viewed as a form of political marketing.
Because that form of marketing is based in delaying responses — it results in ever more egregious harm. And the funders and supporters of denial are involved in criminal activity in which the victims are us all.
Jindal, for example, was attacking Obama for supporting climate action. I suppose Jindal doesn’t care too much that New Orleans and all of southern and eastern Louisiana is being devoured by the Gulf? The land there wouldn’t be subsiding so much if not for the oil industry. And, of course, the Gulf wouldn’t be rising, the storms intensifying at their strongest. Jindal serves no interest but that fulfilled by the short-term profits of fossil fuels. He certainly does not have the interests of the people of Louisiana anywhere on his single-band radar. In fact, every word he utters in his assault on climate action is a betrayal.
Vera Desmond
/ August 26, 2015What is your advice Robert for someone living at the edge of the sea in wild, wet and windy West Cork in Ireland,should I head for higher ground. This has been an unbelievably wet and disappointing summer, the wind never stops blowing and it is very cold most of the time. The Emerald Isle has never looked so beautiful though. I read your posts and try to spread the word but people won’t listen until it is too late.
robertscribbler
/ August 26, 2015Are you on low land, at near sea level, close to the coast?
Vera Desmond
/ August 26, 2015I live about 10 metres above sea level. In a fierce storm a few years ago the sea innundated the land and we had to replace 6 metres by 20 metres of land. We also lost 11 trees and our area was devastated.
robertscribbler
/ August 26, 2015It’s a tough decision to make. But if I were in your shoes, I’d move to higher ground. The issue is twofold. You’re dealing with both sea level rise and storms. And though sea level rise for your area won’t be as bad as for the U.S. East Coast, the storms are likely to be far worse.
If you’ve got land loss now, the situation is only going to get worse. The storms you’ve seen so far are milder versions of what’s coming.
One last point. Eventually many coastal dwellers will figure this out sooner or later. Better to get out ahead of the rush.

In mid June Portland had some seemingly un-PNW like clouds that caught my attention.
This was as a hot dry weather pattern followed by explosive wildfires.
I too photos and made some mental notes which I posted at dtlange2.
‘An array of odd clouds over PDX PNW 0615 — Plus a summation based on ground observations.

– This past June I was startled to see some really odd looking clouds over me. The weather that day was unseasonably warm but not too unusual. These clouds were mostly in the lower to mid levels of the atmosphere.
New oddities showed up over a number of days.
During this time a hot dry ridge of high pressure was setting up over the PNW that has held until this writing on August 26.

/ August 27, 2015DT, we had unusual clouds today here in the Grove also. Maybe it is part of this front coming in that is supposed to bring rain by Friday night. I’m almost holding my breath for this rain. Things are drier here than I’ve seen in my 12 years in Oregon. We have Ponderosa pines on our property that are turning brown and probably dying from the drought stress. We may get a downpour, but the ground is so dry and riven by crevasses that it will probably soak up a lot, even if it comes down pretty hard.
dtlange

These harbingers came quickly, then changed just before a very dramatic climate shift.

csnavywx
/ August 27, 2015The wispy clouds are a mix of cirrus castellanus and cirrus uncinus. The long, wispy tails are streams of ice crystals and snow falling from their bases and streaking into the lower layers of the atmosphere, sublimating and evaporating as they fall. They’re most often seen a couple of days ahead of an advancing upper level trough and signify moistening and destabilization of the upper layers of the atmosphere.

PlazaRed
/ August 26, 2015Its been on the cards for a while I suppose. just needed somebody to write it all down.
Thanks for the heading, here’s a line from it:-
“The long term forecast, however, is even worse. With Greenland just beginning to shed more and more of its ice, the cool pool off England will tend to intensify even as the hot pool off the US East Coast and within the Gulf of Mexico heightens.”
As Winston Churchill said after the first battle of Britain.
“This is not the end, its not even the beginning of the end but maybe its the end of the beginning.”
looking at it as if from an extra terrestrial point of view, there is probably nothing much now that can be down about it.
Things are going to change!

/ August 26, 2015What do you think fall and winter will be like in Central Europe?
Fall: warm and dry (persisting ridge, remaining summer heat?) and winter: normal and wet (northwesterly winds)? Which role does El Niño play and could it be overridden by the changed SST patterns? I thought winter would be not that cold and snowy in Eastern US than last winter.. could that mean it will be a bit colder in Scandinavia and in the countries south of it?
PlazaRed
/ August 26, 2015If the pattern persists the way it is at the moment with storms being formed over the Newfoundland area and moving over to Britain then the centre of Europe will have a relatively mild time as there will be a lot of warm southerly’s coming up from the Mediterranean and also a lot of wet weather coming in on westerly’s.
If the low pressures start to dip over France then they could bring a lot of northerly winds to central Europe but the UK will suffer them first and probably very badly.

/ August 26, 2015I have the greatest respect for Professor Stefan Rahmstorf and for all of the good work that the Potsdam Institute is in involved, and his paper on the AMOC was remarkable. This Ocean current has been involved in so many shifts in climate in Earth’s rich history. The National Oceanography Centre monitors the current and has regular updates on the state, and is worth following. It is likely to have a large impact on the global climate in the future, and is one of the abrupt climate change indicators. I hope to see an International Early Warning System set up as recommended by a group of top scientists some time ago.

“To address these needs the Committee recommends development of an Abrupt Change Early Warning System (ACEWS). Surprises in the climate system are inevitable: an early warning system could allow for the prediction and possible mitigation of such changes before their societal impacts are severe. Identifying key vulnerabilities can help guide efforts to increase resiliency and avoid large damages from abrupt change in the climate system, or in abrupt impacts of gradual changes in the climate system, and facilitate more informed decisions on the proper balance between mitigation and adaptation. With adequate scientific monitoring and study of these potential changes to the climate system, the probability that society can anticipate future abrupt climate
changes and impacts will be substantially increased.”

/ August 27, 2015Meanwhile, the IMPACTS (Impacts of Abrupt Climate Change) group of national labs and universities seems to have been quietly disbanded. Their website lists 5 years worth of papers, but has not been updated since 2013. They ran from 2008 to 2013, and their funding apparently expired.
It’s a shame, they were doing great work, from what I’ve seen. Unrealistically conservative, I think, but really solid and detailed, with the computer resources of the national labs and universities modeling things like methane hydrate dissociation and droughts.
http://esd1.lbl.gov/research/projects/abrupt_climate_change/impacts/publications.html

/ August 27, 201515-30% slowing of the Gulf Stream already ,with less than 1C of Global Warming, points towards worse case scenario in the not distant future, wouldn’t you think? CO2 in the atmosphere is increasing yearly,
Greenland is melting much faster than we expected. So the dice look heavily loaded.
Another thing not mentioned. Back in the late 80’s, some were pointing to possible increased outflow of Siberian and Arctic rivers dumping masses of fresh water into northern seas. This, it was said, posed a threat to the sinking zone between Iceland and Norway. Where the migration of fresh water would produce slower sinking. Is there any evidence that this North Eastern source of fresh water is indeed on the increase. A double whammy is not a good thing, with fresh water flowing out from West [Greenland] and East [Arctic rivers and Siberian rivers].

I will be keeping an eye on my old home (UK) over the autumn and winter to see what transpires. But I expect it’ll be another record-breaking wet season!
Meanwhile, in New South Wales, as we are just about to welcome in spring in Australia, massive floods have hit a wide area of NSW, with some places receiving 400mm of rain in 2-3 days. Not only that but dams are at risk of overflowing and causing massive flodding downstream. Evacuations have taken place.
http://www.abc.net.au/news/2015-08-26/hundreds-evacuated-flooding-nsw-st-georges-basin/6725040
With the powerful El Nino becoming ever-more powerful, expect to see heatwave stories coming out of Australia in a few months. Indeed, potentially a few weeks. It’s not uncommon in Australia to have places that have been flooded have bush fires a matter of weeks later.
It all adds up to a feeling that when we’re told that action on climate change is urgent, but it’s not too late, that actually it IS too late. I have 2 kids under 10. I’m thinking that living in Perth, removed from much of the worst of the affects of our changing climate, isn’t too bad really – but I do fear for them and what the world will be like when they’re looking at having their own children.

” Satellite images show that the fastest moving glacier in the world shed a chunk of ice measuring around 12.5 sq km this week – one of the most significant calving events on record.
Radar images from Sentinel-1A captured the Jakobshavn glacier in western Greenland before and after the event, which took place between 14 and 16 August.
Comparing images taken on 27 July, and 13 and 19 August, the new face of the glacier has been pushed inland by several kilometres to what appears to be its furthest easterly location since monitoring began in the mid-1880s.
The image time series suggests that between 27 July and 13 August, the glacier advanced westward before the calving caused rapid retreat of the ice front to its position on 19 August.
It is estimated that the glacier lost a total area of 12.5 sq km. Assuming the ice is about 1400 m deep, this equates a volume of 17.5 cubic km – which could cover the whole of Manhattan Island by a layer of ice about 300 m thick.”

jyyh
/ August 27, 2015umm, let’s remember the “dismal” (or rather, abnormally cool) weather all across northern Europe this past summer has likely been partly due the atmospheric reorganization associated with the development of El Nino. This somewhat changes the distribution of lows and highs in Arctic boosting the northern cold component of all systems moving in northern Europe. This should revert back to more normal stuff once Nino is fully developed, I guess.

robertscribbler
/ August 27, 2015The North Atlantic cool pool is not a feature of El Nino. It’s a feature of Greenland melt. And that feature is having profound impacts on climate.
However, there does appear to be a synergy between El Nino and drought/heat in eastern Europe and this particular El Nino may be developing a synergy with an already amplified North Atlantic storm track.

Alex Smith
/ August 27, 2015There are other factors at play that might account for some (but not all) of this sea level rise off New England. On April 1, 2015 I interviewed scientist Paul Goddard about his research on why sea level went up over 2 inches in New England in 1 year. (And then went down again a couple of years later). As I recall, he thought wind piling up the water was a factor. You can download that interview (about 15 minutes) here:

robertscribbler

Syd Bridges
/ August 27, 2015All these predictions are coming to pass in a much shorter time span than most scientists thought. I am at present in Colorado, but am returning to my home country, England, about a week before Christmas. The winter of 2013-4 there was bad enough but I’m wondering whether I will return to much worse this year. Reading about flooding in areas of North London, that I used to walk through is bizarre, especially following on from the rains in Tunbridge Wells, were we regularly visited when I was a child.
I do hope that if the downpours of August continue there, that Downing Street and the Houses of Parliament get hit hard. The spectacle of David Cameron and George Osborne having to be rescued from upstairs windows and lots of bedraggled MPs in launches, would at least give some great schadenfreude, even if it wouldn’t actually bring any sanity to the Government.
Meanwhile, on the other side of the Atlantic, what next for the Jersey Shore? I used to visit the beaches from Sandy Hook to Point Pleasant.

In Siberia, officials have been aware of high carbon monoxide readings for quite a while, apparently – they have been warning the population against smoking or drinking alcohol – which would also increase carbon monoxide or decrease oxygen levels in the blood.

Oh, I found out about earthnullschool here on robertscribbler. Isn’t it amazing?
Yes, I’ve also been watching the remnants of typhoon Atsani on earthnullschool, which could bring rain and snow to Alaska. I think some of the moisture is circling around the Ridiculously Resilient Ridge. This seems to be creating storms that could come down through the Pacific Northwest toward the end of the week, and maybe reach even into northern California.
http://phys.org/news/2015-08-nasa-typhoon-atsani-remnants-affecting.html
These storms are also transferring equatorial heat to Alaska, as Robert pointed out a week or so ago, a new storm track.

Yes. I wonder if the smoldering fires we are seeing in areas with combustible soils will create higher CO spike levels in the future? Are health effects from CO exposure another unanticipated side effect of global warming?
Leland Palmer
/ August 27, 2015Acute carbon monoxide poisoning can also create delayed reactions, apparently. Exposure to the levels we are seeing in the open air will probably not create acute poisoning, except perhaps in susceptible individuals. Delayed reactions (sequelae) can occur:
http://archive.rubicon-foundation.org/xmlui/bitstream/handle/123456789/9800/SPUMS_V22N3_3.pdf?sequence=1
Quote:
DELAYED SEQUELAE
Delayed neuropsychiatric sequelae develop between
two and twenty one days following exposure, often after
apparent recovery from the acute insult.10,75 Higher functions
are impaired, especially short term memory. Psychometric
abnormalities may reappear. Korsakoff’s syndrome may
occur. Personality changes range from apathy to unconcerned
incontinence. Ataxia, incontinence and Parkinsonism
may develop.34,44 Almost any neurological syndrome
may be produced.
In a series of 206 patients treated by Smith and
Brandon in the 1960’s, only the more severely affected were
given 100% oxygen at atmospheric pressure. There was a
33% mortality rate. Only 2.2% of the 138 survivors had
neuropsychiatric sequelae at discharge.76 When reviewed
three years later the situation was considerably different as
10.8% had gross neuropsychiatric deficits, 28.4% had an
obvious personality deterioration and 36.5% had some loss
of memory.7
The clinical state at the scene of poisoning correlates
better with the risk of sequelae than does the clinical state on
arrival at hospital.10,14,77 Variable recovery occurs in 75% of
survivors at one year.78 Characteristically the most severe
delayed sequelae are seen in the elderly and in children.8
Delayed sequelae are more common following severe poisoning.
Depression occurs frequently, even in patients who
do not attempt suicide. Following an attempted suicide, it is
often difficult to diagnose an antecedent psychiatric disorder
due to the presence of the neurological and psychiatric
sequelae of CO intoxication.79
Unquote
All of this is from acute CO poisoning, not the lower levels we are seeing in the open air. Still, in children or fetuses, or heart patients or the old, or in people who are drinking or smoking at the time of the exposure… don’t know.

“New research confirms that the land under the Chesapeake Bay is sinking rapidly and projects that Washington, D.C., could drop by six or more inches in the next century—adding to the problems of sea-level rise.
This falling land will exacerbate the flooding that the nation’s capital faces from rising ocean waters due to a warming climate and melting ice sheets—accelerating the threat to the region’s monuments, roads, wildlife refuges, and military installations.”
““Right now is the time to start making preparations,” said DeJong. “Six extra inches of water really matters in this part of the world,” he says—adding urgency to the models of the Intergovernmental Panel on Climate Change that project roughly one to three or more feet of global sea-level rise by 2100 from global warming.
“It’s ironic that the nation’s capital—the place least responsive to the dangers of climate change—is sitting in one of the worst spots it could be in terms of this land subsidence,” said Paul Bierman, a UVM geologist and the senior author on the new paper. “Will the Congress just sit there with their feet getting ever wetter?
