The warming Arctic is both a result of global warming and key contributor to it. Reduced sea ice in the summer occurs because of a warming atmosphere and ocean. With dark water absorbing more solar energy than
reflective sea ice, it accelerates global warming as well. Calving of icebergs from glaciers and growing melting of the Greenland ice sheet is further impacting the composition and temperature of northern oceans.Thawing permafrost has become a source instead of a sink for heat trapping carbon dioxide and methane. So what can be done? As part of an ongoing Fletcher School initiative, a group of experts, policy makers, business and
media will convene to examine the critical interaction of the Arctic and global climate change – and share some fresh ideas to address it!
