A study that looks at the Arctic’s role in absorbing carbon dioxide finds that the job of storing CO2 could be over in coming decades and the Arctic may become an emitter of carbon dioxide and methane. David McGuire is a USGS and University of Alaska Fairbanks scientist who reviewed past studies and compiled the latest findings. He says since the end of the last ice age, the Arctic has absorbed about 800 million metric tons of global carbon.
