Melting ice feedback loop

Web26 sep. 2016 · By my calculations, the terrestrial warming in the Arctic is roughly equivalent to a 25 percent boost in global CO2 emissions. This, combined with the warming caused by the loss of Arctic sea ice, means that the overall ice/snow albedo effect in the Arctic could add as much as 50 percent to the direct global heating effect of CO2. WebSea ice begins as thin sheets of smooth nilas in calm water (top) or disks of pancake ice in choppy water (2 nd image). Individual pieces pile up to form rafts and eventually solidify (3 rd image). Over time, large sheets of ice …
