Glaciers and "zombie ice": The planet is melting at both ends, research finds

Salon  

That sea levels will rise as Earth's ice melts is a prophecy that began to come true long ago, at the dawn of industrial civilization when humans began pumping vast amounts of greenhouse gases into the atmosphere. Being the widest glacier in the world, it has been nicknamed the "Doomsday Glacier" — because if it collapses, the consequent rise in global sea levels would flood millions of people out of their homes. "The climate science tells us that we are already into dangerous levels of greenhouse gases that will have consequences far beyond 10 inches of sea level rise." Dr. Sarah Pralle, an associate professor of political science at Syracuse University who specializes in environmental politics and policy, climate change and energy, also told Salon that the new studies suggest "that our previous models of climate change impacts have likely underestimated the scale and timeline of major climate disasters such as sea level rise." "It's a useful study and the main conclusion — that there may be a foot of committed sea level rise from the Greenland ice sheet — seems entirely plausible," Mann wrote.
