Deglacial mobilization of pre-aged terrestrial carbon from degrading permafrost ...
The mobilization of glacial permafrost carbon during the last glacial–interglacial transition has been suggested by indirect evidence to be an additional and significant source of greenhouse gases to the atmosphere, especially at times of rapid sea-level rise. Here we present the first direct eviden...
