The state of the Arctic: High temperatures, melting ice, fires and unprecedented emissions
The Arctic tundra has switched from a carbon sink to a source of emissions, according to a NOAA report.
The Arctic just experienced its second-hottest year on record. And concerningly, the region’s tundra has transitioned from being a sink for carbon to a source of emissions as permafrost thaws, releasing carbon dioxide and methane.
That will only amplify the amount of heat-trapping gases that enter the atmosphere, paving the way for further warming.
