Another ice-shelf breaks up

This time it's the Ward-Hunt Ice Shelf, on the northern coast of Ellesmere Island (that's the big blob right up the top of Canada, for the geographically challenged). Not as spectacular as last year's breakup of the Larson B shelf in Antarctica, but still notable.

So, how many times does this have to happen before the global-warming deniers pull their heads out of their arses and face reality?
