A new study has found that the massive Laurentide ice sheet that covered Canada during the last ice age initially began shrinking through calving of icebergs, and then abruptly shifted into a new regime where melting on the continent took precedence, ultimately leading to the sheet's demise.

David Vaughan of the British Antarctic Survey says the calving of an iceberg the size of Oxfordshire from the Larsen Ice Shelf was not necessarily unusual. (newscientist.com)
