As a consequence of global warming, Antarctic ice shelf on the brink of breaking up.

An ice bridge linking a shelf of ice to two islands in Antarctica has shattered “and may herald a wider collapse caused by global warming.” Scientists say the collapse could mean the Wilkins Ice Shelf — which is about the size of Connecticut — is on the brink of breaking up. It would be the largest slab of ice so far to disintegrate and retreat in the Antarctic. “The rapid retreat of glaciers there demonstrates once again the profound effects our planet is already experiencing — more rapidly than previously known — as a consequence of climate change,” Interior Secretary Ken Salazar said in a statement. An international meeting of Antarctic and Arctic scientists will report in Baltimore tomorrow that “up to one-third of all Antarctic sea ice is likely to melt by the end of the century, seriously contributing to dangerous sea level rises.”
