Looks like climate change feedback has arrived in the Arctic


Permafrost…melts into the Kolyma River outside Zyryanka, Russia

” The Arctic is undergoing a profound, rapid and unmitigated shift into a new climate state, one that is greener, features far less ice, and is a net source of greenhouse gas emissions from melting permafrost, according to a major new federal assessment of the region released Tuesday.

The consequences of these climate shifts will be felt far outside the Arctic in the form of altered weather patterns, increased greenhouse gas emissions, and rising sea levels from the melting Greenland ice sheet and mountain glaciers.

” The findings are contained in the 2019 Arctic Report Card…Especially noteworthy is the report’s conclusion that the Arctic may have already turned into a net emitter of planet-warming carbon emissions due to thawing permafrost, which would only accelerate global warming. Permafrost is the carbon-rich frozen soil that covers 24% of Northern Hemisphere land area, encompassing vast stretches of territory across Alaska, Canada, Siberia and Greenland…

” “These observations signify that the feedback to accelerating climate change may already be underway,” the report concludes.

“Each of the studies has some parts of the story. Together they really paint the picture of – we’ve turned this corner for Arctic carbon,” said Ted Schuur. “Together they complement each other nicely and really in my mind are a smoking gun for this change already taking place.”

RTFA. Read it and weep for the damage we have done…continue to do under the “leadership” of the League of Corporate Pimps in Washington, DC. Otherwise known as Congress, the White House and the Federal Government.

    “Deep Frozen Arctic Microbes Are Waking Up : Thawing permafrost is releasing microorganisms, with consequences that are still largely unknown” (Scientific American Nov. 20, 2020) https://www.scientificamerican.com/article/deep-frozen-arctic-microbes-are-waking-up/
    “Permafrost covers 24 percent of the Earth’s land surface, and the soil constituents vary with local geology. Arctic lands offer unexplored microbial biodiversity and microbial feedbacks, including the release of carbon to the atmosphere.
    …we must come up with guidelines for future Arctic research. As travel through the region increases, the likelihood of pathogen export and import rises as well. The planetary protection guidelines that space agencies follow to prevent interplanetary contamination can provide a framework for how microbial investigation can safely continue. Biosurveillance measures must be put into place to protect communities in the Arctic and beyond. As the Arctic continues to transform, one thing is clear: as climate change warms this microbial repository during the 21st century, the full range of consequences is yet to be told.”
