Study: Climate models underestimate permafrost emissions

JUNEAU, Alaska (AP) – Global climate projections have drastically underestimated carbon emissions from thawing permafrost in the Arctic, a new study suggests.

The study published in the peer-reviewed journal Nature Communications indicated that permafrost emissions could be more than double what has been projected because of the methane from thermokarst lakes, which form in permafrost, Alaska's Energy Desk reported Monday.

Scientists have previously projected that the Arctic could absorb as much or more carbon than emitted partly

because of additional plant growth from warmer temperatures. Tak...
