A recent study published in Science Advances indicates that permafrost may shift from a carbon sink to a source earlier than expected, around the 2050s, due to the inclusion of previously ignored deep soil carbon in models.

Where
Arctic and northern high latitudes ·
Why
The Arctic and northern high latitudes are warming about 2–4 times faster than the global average, causing ancient permafrost to thaw and release stored carbon, which, when deep carbon deposits are accounted for, leads to a reversal from a carbon sink to a source.
The Frontline Impact

How this affects you

This recalibration of climate models suggests a more immediate and significant release of greenhouse gases from thawing permafrost than previously understood, demanding urgent attention to the amplified feedback loop contributing to global warming. The inclusion of deep carbon dynamics provides a more accurate picture of future permafrost carbon climate feedbacks.
