Gore: Polar Ice May Vanish In 5 Years

Posted by Trish Riley, December 15, 2009

Gore and Danish ice scientist Dorthe Dahl Jensen clicked through two slide shows for a standing-room-only crowd of hundreds in a side event at the Bella Center conference site.

…what’s happening to Greenland’s titanic ice sheet “has really surprised us,” said Jensen of the University of Copenhagen.

She cited one huge glacier in west Greenland, at Jakobshavn, that in recent years has doubled its rate of dumping ice into the sea. Between melted land ice and heat expansion of ocean waters, the sea-level rise has increased from 1.8 millimeters a year to 3.4 millimeters (.07 inch a year to .13 inch) in the past 10 years.

Jensen said the biggest ice sheets – Greenland and West Antarctica – were already contributing 1 millimeter (.04 inch) a year to those rising sea levels. She said this could double within the next decade.

“With global warming, we have woken giants,” she said.
