Where
Arctic and northern high latitudes ·
Why
The inclusion of deep permafrost and peat carbon, particularly Yedoma deposits, and a more accurate representation of permafrost formation history, reveals a faster degradation of deep permafrost carbon.
The Frontline Impact
How this affects you
This updated understanding of permafrost's role as a carbon source earlier in the century implies potentially faster climate warming due to increased greenhouse gas emissions from thawing permafrost soils, challenging previous climate model assumptions.
