Greenland's Ice Island Breaks Off

greenlandOn August 9th, a massive sheet of ice (the size of Manhattan times 4 and half the size in height of the Empire State Building) broke off from the Artic called the Petermann Glacier. There is much to be concern according to scientists, especially the eventual contribution to rising sea levels. Climate change and global warming, everybody! We must not ignore this!

A giant iceberg that snapped away from Greenland last week is a signal that global warming is causing the island's continent-sized ice cap to melt faster than expected, scientists say.

The 250-square-kilometre (100-square-mile) chunk, four times the size of Manhattan, broke away from the Petermann ice shelf on Greenland's northwestern tip.
The breakoff -- the largest in the Arctic in half a century -- points to Greenland's worrying potential to stoke sea levels in the coming decades and centuries, climate experts say.
 
"It is a warning sign that we are seeing changes," said University of Colorado glaciologist Konrad Steffen, who is overseeing the Greenland section of a major report by the UN Intergovernmental Panel for Climate Change (IPCC), due in 2013. "The ice sheet is continuing to lose volume at an accelerated rate," he said by phone.
 
"We are now at 350 cubic kilometres (84 cubic miles) ice loss per year. That's more than twice the ice in all the glaciers in the Alps." If it melted completely, Greenland's ice sheet could boost the global water mark by at least five metres (17.5 feet). Link


This is an iceberg 4x the size of Manhattan that will melt into the sea. Its implication are still unknown. Scientists and environmentalist are calling this a result of global warming. We have hit record high temperatures! The sea is getting warmer and this still doesn't seem to phase Conservatives that continues to believe this is all a myth!

Environmentalists say ice melt is being caused by global warming with Arctic temperatures in the 1990s reaching their warmest level in any decade in at least 2,000 years, according to a study published in 2009. Current trends could see the Arctic Ocean become ice free in summer months within decades, researchers predict. Link

Global warming is a fact. Just because we have an occasionaly sever winter does not reverse the trend. New Orleans is destined to be under water as is most of Florida, Holland, Venice and costal regions throughout the world.
