March 2015 Research Arctic sea ice is 'thinning dramatically'

The sharp decline in summer Arctic sea ice is unprecedented, and consistent with human-induced climate change (Climate Change in the United States USGC May 2014 )

We are at risk of pushing our climate system toward abrupt, irreversible change
What we know AAAS March 2104

We are in a state of planetary emergency
James Hansen 19 Sept 2012 - repeating his emergency warning of 2008, in response to the 2012 summer sea ice record low.

"The fall-off in ice volume is so fast that it is going to bring us to zero very quickly. 2015 is a very serious prediction and I think I am pretty much persuaded that , that's when it will happen."
