Sea Level Rise Could be more than twice as high as 2007 IPPC Projection #green
The Arctic temperature increase and the decline of snow and ice feed upon themselves, in an accelerating feedback loop that is causing more rapid melting and sea level rise. The reflective Arctic ice and snow act as a protective shield, sending solar radiation into space. As the ice and snow disappears it is replaced by darker seawater or land, which absorbs more of the incoming radiation. This absorbed energy is released as heat during the summer months, further adding to Arctic warming, which in turn accelerates melting.
