The National Snow and Ice Data Center at UC Boulder concurs, and there is no disputing that 2007 was a record year for Arctic sea ice melt. That doesn’t bode well for future temperature rises, since the ice acts as a giant sun reflector, and helps cool the oceans.

But hey, looking at the bright side, at least the fabled Northwest passage is now open in summertime!
