Volcanic Activity and Mass Extinctions, 2012 Movie

The green house gas, methane, that is released from the melting northern ice may not be the only problem. You may have heard that the white ice reflects energy and heat back into space, the green house gas reflects it back, trapping it. What you may not have heard is that this energy that is not reflected back into space by the white ice may increase the planetary core temperature, and this may be linked to volcanoes. Super volcanoes may be the cause of one of the past five planetary mass extinctions.
