“Permafrost warming in Alaska is reaching considerable depths as Arctic Amplification pushes surface air warming past 1.15°C per decade. A 27-year study shows warming deeper than 1m across 100% of measurement sites.
According to the study [link above], some permafrost soils show 2-3°C per decade warming rates at 1.2 metre death during the winter months. This has infrastructure implications as well as climate feedback effects.
The relationship between air and soil temperatures was significantly impacted by the presence of snow in the winter months. The correlation between air and soil temperatures was weakened by the presence of snow in each permafrost region, particularly those with deeper snowpacks. As the air warms at much faster rates in the Arctic, snow levels and pack duration are declining rapidly.
Permafrost melt is hugely important as a future natural carbon source and warming feedback. The International Cryosphere Climate Initiative (www.iccinet.org) project permafrost emissions of greenhouse gasses rivalling the US or China today as the world passes 3°C - something that the current trajectory points to happening within 50 years. The implications for the chances that net-zero can slow warming are obvious…”
