NOTE ON POPULAR POSTS

His findings suggest that glaciers can undergo a self-amplifying cycle of melting and warming that would be hard to stop.

'We are finding that even if you don't have record-breaking highs, as long as warm temperatures persist you can get record-breaking melting because of positive feedback mechanisms,' said Professor Tedesco, who directs CCNY's Cryospheric Processes Laboratory and also serves on CUNY Graduate Centre doctoral faculty.
