Arctic ocean may absorb less CO2 than projected due to coastal erosion

LA Times  

As Earth warms, the Arctic Ocean’s ability to absorb carbon dioxide from the atmosphere is waning due to melting permafrost and worsening coastal erosion, according to new research. “For the first time, we can actually put a sign — maybe not a number but a sign — on the change in the Arctic Ocean’s ability to take up CO2 from …

Arctic ground ‘literally collapsing’ amid abrupt thaw

Al Jazeera  

Experts say global emissions need to be cut now to limit the release of powerful greenhouse gases from thawing permafrost. Permafrost’s polluting potential begins when the damper, warmer conditions of thawing ground jumpstart microbes to produce carbon dioxide or methane as they feast on decomposing organic matter in boggy, once-hard soil. ‘Abrupt thaw’ The increasing frequency and severity of Arctic …
