Remobilization of dormant carbon from Siberian-Arctic permafrost during three past warming events.
Jannik Martens, Birgit Wild, Francesco Muschitiello, Matt O'Regan, Martin Jakobsson, Igor Semiletov, Oleg V Dudarev, Örjan Gustafsson
Oct 20, 2020
Carbon cycle models suggest that past warming events in the Arctic may have caused large-scale permafrost thaw and carbon remobilization, thus affecting atmospheric CO2 levels. However, observational records are sparse...
