Permafrost is warming at a global scale. First global comprehensive assessment since the Polar Year ⁦
"Permafrost warming has the potential to amplify global climate change, because when frozen sediments thaw it unlocks soil organic carbon." Published on 16 January 2019 @350
The first globally consistent assessment of recent permafrost temperature change by the Global permafrost monitoring community published in Nature Communications today
New first-of-its-kind global study confirms our story from August: permafrost is thawing fast, especially in Siberia, and snow is helping drive the change, driving fresh worries abt greenhouse gases. h/t
#GSC scientist Sharon Smith is a coauthor of this study in Nature Communications that for the first time evaluates permafrost temperature change across the world's permafrost regions since 2009. Globally, permafrost temps increased by 0.29 +/- .12°C. More:
That was probably the case a few years ago. describes a permafrost warming rate that came as a big, nasty surprise, and that's not even counting all the recently described loss mechanisms.
ESM values? Per , this year's big permafrost paper, "This process is expected to augment global warming by 0.13–0.27 °C by 2100 and by up to 0.42 °C by 2300. Despite this, permafrost change is not yet adequately represented in most of the Earth System 1/
