WASHINGTON (Reuters) - One Antarctic ice shelf has quickly vanished, another is disappearing and glaciers are melting faster than anyone thought due to climate change, U.S. and British government researchers reported on Friday.
They said the Wordie Ice Shelf, which had been disintegrating since the 1960s, is gone and the northern part of the Larsen Ice Shelf no longer exists. More than 3,200 square miles (8,300 square km) have broken off from the Larsen shelf since 1986.
The U.N. Climate Panel projects that world atmospheric temperature will rise by between 1.8 and 4.0 degrees Celsius because of emissions of greenhouse gases that could bring floods, droughts, heat waves and more powerful storms.
Climate change is to blame, according to the report from the U.S. Geological Survey
Scientists suggest the collapse.....provides evidence of global warming.
The shelf has been retreating since the 1990s ........ David Vaughan, a glaciologist with the British Antarctic Survey, was quoted as saying by Reuters news agency, "Two days ago it was intact. We've waited a long time to see this." ......
They say the Antarctic Peninsula has experienced unprecedented warming over the last 50 years.
