How can sea ice or snow cover affect climate
Web6 de dez. de 2012 · Some scientists believe that, at this rate, the Arctic could be ice-free by 2030 or even earlier. The Arctic may seem remote, but the overall rate of global warming, our climate and weather, sea levels, and many ecosystems and species will be affected by the warming that is occurring there. The Arctic includes the Arctic Ocean and northern ... WebSea ice floes range in size between 10 m and 5 km wide and are of the order of 0.5 to 5 m thick. Areas of open water between ice floes are called "leads". Snowfall remains on the floes all year round and over winter can get to 10-20 cm deep. Sea ice floes can freeze together and can be broken by collisions or ocean waves.
