Global warming is increasing the risk of catastrophic glacier detachments, geologists have warned. Meltwater generated by warmer summers is posing a new threat “that we are only just beginning to understand”, according to researchers who investigated what unleashed a torrent of ice and rock that slid for seven miles through a valley in Alaska.
