Story summary

A University of Gothenburg study shows thawing permafrost significantly increased carbon dioxide levels after the last ice age, possibly by nearly 50%.
Northern land areas emitted considerable carbon as temperatures rose post-ice age.
Peatlands absorbed 450 petagrams of carbon over the Holocene, mitigating permafrost emissions.
Current climate challenges include rising sea levels and decreased land for carbon storage, complicating future management efforts.
