'Squishy' ice alters climate models, study says - U.S. news - Environment - Climate Change - msnbc.com

To put it in non-scientific terms, lead scientist Robin Bell told msnbc.com, the study redefines "how squishy" the base of ice sheets can be. "This matters to how fast ice will flow and how fast ice sheets will change."

"It also means that ice sheet models are not correct," she said, comparing it to "trying to figure out how a car will drive but forgetting to add the tires. The performance will be very different if you are driving on the rims."

"I think it is an astounding discovery," added Scambos, who was not involved with the study. "Who knew that a buried mountain range would let you grow the ice sheet from underneath?"
