Climate Change Affects in the Arctic

The climate change is affecting the arctic greatly, due to global warming. First, the arctic sea ice is melting, by the summer of 2009, the thickness of the sea ice, has been cut down to a dramatic half of what it was in the 1950's. Melting ice can lead to changes in ocean water circulation. Plus with all the sea ice already melting, this affects the warming in the arctic by speeding it up.
