Arctic Sea Ice at 4th Lowest Extent on Record

Warmer than normal conditions, abnormal wide areas of open water, large wildfires burning near Arctic Ocean shores, and Arctic sea ice extents at 4th lowest on record. That’s the present reality of a human-warmed Arctic environment.

(An assessment of present Arctic conditions)

With Arctic temperatures hovering around 1.6 degrees Celsius above average and focusing on a rather hot zone near Central Siberia, Arctic sea ice on the Siberian side is experiencing widespread melt ponding. In addition, a large area of open water is expanding through the Laptev Sea due to warm southerly winds and much warmer than normal temperatures.

Overall, temperatures in this Central Siberian zone will range as high as 25 degrees Celsius (45 F) above average today. With some areas hitting has high as 85-90 (F). Near these much warmer than normal temperatures, a series of large wildfires are burning. Fires so far north are historically rare. But they have become more common as the Earth has warmed due to fossil fuel burning.

(Arctic temperatures are well above average for this time of year. These much warmer than normal temperatures are contributing to a number of impacts, including lower than normal sea ice extent.)

Present sea ice decline rates now put Arctic Ocean ice extent at 4th lowest on record. And the present trajectory for Arctic sea ice appears to be aiming toward approximately 4 million square kilometers come melt season end. However, with human-forced warming now resulting in ever-increasing global temperatures, downside risks remain. Particularly with so much heat moving about in the Arctic.

    The Guardian: Leaked UN draft report warns of urgent need to cut global warming.

    Human-induced warming would exceed 1.5C by about 2040 if emissions continued at their present rate, the report found, but countries could keep warming below that level if they made “rapid and far-reaching” changes.

      “Global warming set to exceed 1.5°C, slow growth – U.N. draft”

      https://www.reuters.com/article/us-climatechange-report-exclusive/exclusive-global-warming-set-to-exceed-1-5c-slow-growth-u-n-draft-idUSKBN1JA1HD

      OSLO (Reuters) – “Global warming is on course to exceed the most stringent goal set in the Paris agreement by around 2040, threatening economic growth, according to a draft report that is the U.N.’s starkest warning yet of the risks of climate change.

      Governments can still cap temperatures below the strict 1.5 degrees Celsius (2.7° Fahrenheit) ceiling agreed in 2015 only with “rapid and far-reaching” transitions in the world economy, according to the U.N.’s Intergovernmental Panel on Climate Change (IPCC)… ”

      “‘ “Economic growth is projected to be lower at 2°C warming than at 1.5° for many developed and developing countries,’ it said, drained by impacts such as floods or droughts that can undermine crop growth or an increase in human deaths from heatwaves.”

    Not good……

    “After holding steady for the last three years global CO2 levels started edging back up in 2017.
    Heavy industry is picking up again in China; coal is growing quickly in India and ticked up again in China after years of decline.
    In 1978 coal represented 38% of energy production. In 2017 it represented … 38% of global production.
    For all the bad news it has received lately, coal remains the greatest threat to a stable climate and a logical first target for a world serious about decarbonizing. It has got to go.”

    We are still talking about the money details regarding the Paris agreement but basically it will involve historical big polluters (EU, US when they grow up) paying more then developing nations. This is ok. But what we need to do is ASAP is get some fund going which helps developing nations develop renewable energy.

    Basically look where they are planning to build big coal generation and give them alternatives. If only you start doing this for India and Indonesia this can take out big chunks of carbon sources going forward. Ideally the program should work for all countries later on but we got to start before bureaucrats finalize details.

    Investing into mitigation/prevention will give such a good return on investments. We really have to stop looking at this from country perspectives and go planetwide.

    So many birds & insects wondering where their food went… and plants wonder where their pollinators went. 😦

    Unusually Hot Spring Threw Plants, Pollinators Out of Sync in Europe

    VIENNA, AUSTRIA — In a patch of scruffy prairie near Vienna, marbled white butterflies hover near clusters of unopened globe thistles. They uncurl their long proboscises to probe the spiky buds—without success. It’ll be a couple more weeks before the flowers open, but some of the butterflies may not survive that long if they don’t find something else to eat.

    Two months of unusually high spring temperatures in Europe have thrown the ecosystem in this urban wilderness meadow out of whack, says butterfly expert Marion Jaros. The warm temperatures accelerated the hatch of many butterflies and other pollinating species, but the flowers they depend on for nectar are not responding in sync.

  8. Well two days after this article was written, Arctic Ice has slipped from fourth worst to third worst! Does anyone have the capacity to put Arctic ice concentration maps from different years side by side showing the percentage of the ocean covered in ice?
