Arctic Ice Melt Effects

Surface Heat Budget Of The Arctic Ocean - Wikipedia
Snow-covered sea ice reflects about 80% of the incident sunlight. Seasonal changes in the Arctic result in clear skies and radiational cooling from snow-covered sea ice in the constantly dark arctic winter. In spring, with the return of sunlight, melt pools begin to form and increase the rate of heat absorption from the sun. ... Read Article

Relationships Between Arctic Sea Ice And Clouds During Autumn
Ice extent has decreased markedly over the last few decades (Cavalieri et al. 2003; Serreze et al. 2007, 2003). The more recent (since 1988) decrease is thought to be the result of the combined effects of gradual warming, changes in the atmospheric and oceanic circulation pat-terns, and the ice–albedo feedback (Lindsay and Zhang 2005). ...
