Warming has more impact than cooling on Greenland's 'firn,' physics-based model reveals
Scientists have known from ice core research that it's easier to melt an ice sheet than to freeze it up again. Now, they know at least part of the reason why, and it has to do with ice's "sponginess," according to a new study ...
