Short summary
We used a model to quantify the carbon stock and its changes in terrestrial ecosystems of Alaska during the last 15 000 years. We found that the changes in vegetation distribution due to climate were the key factors in the spatial variations of carbon in different time periods. The warming during 11–9 k years ago characterized by the increased summer temperature and seasonality of radiation, along with the high precipitation, might play an important role in causing the high carbon accumulation.
