Older, more stable ice melting as well
By Rik Myslewski
A prominent British Arctic scientist and researcher says that the continued and accelerated melting of the polar sea-ice cap is not only a result of climate change, but is also a massive contributor to it.
In perhaps an overly simplistic nutshell, sea ice is reflective, bouncing solar energy back into space. When it melts, the darker open sea absorbs more of that energy, increasing ocean temperatures.
How much more? According to Professor Peter Wadhams of the University of Cambridge’s Polar Ocean Physics Group, that increased absorption has an effect that’s “the equivalent of about 20 years of additional CO2 being added by man.”
