WASHINGTON (Reuters) - The largest ice shelf in the Arctic, a solid feature for 3,000 years, has broken up, scientists in the United States and Canada said on Monday.
"Large blocks of ice are moving out. It's really a breakup," said Warwick Vincent, a professor of biology at Laval University in Quebec and co-author of the report, which will be published in an upcoming issue of the journal Geophysical Review Letters. "We'd been measuring incremental changes each year. Suddenly in one year, everything changed."
Because of their longevity and sensitivity to temperature, ice shelves are considered "sentinels of climate change." The breakup provides more evidence that the Earth's polar regions are responding to ongoing and accelerating rates of climatic change.
