Antarctica is warming more than previously believed and that lmost all glaciers worldwide are retreating

FIle- In this Aug. 17, 2005 file photo glaciers and icebergs of the Greenland ice cap are seen over Greenland. The last decade has been marked by dramatic effects of warming. In 2007-2009, the summer melt has shrunk the Arctic Ocean ice cap to its smallest extent ever recorded. In the 2007-2009 International Polar Year, researchers found that Antarctica is warming more than previously believed and that lmost all glaciers worldwide are retreating. Meanwhile, such destructive species as jellyfish and bark-eating beetles are moving northward out of normal ranges, and seas expanding from warmth and glacier melt are encroaching on low-lying island states

In 2007, M/S Nordkapp, with nearly 300 passengers on board, ran aground in the Antarctic and damaged its hull before getting free of rocks. Officials said Wednesday Dec. 9, 2009, countries that manage Antarctica want strong new controls on ships visiting the frozen continent to reduce the growing threat of human and environmental disasters posed by exploding numbers of tourists.

This undated photo received on December 9, 2009 from the Australian Antarctic Division, courtesy of gsfc/NASA shows a satellite image of iceberg B17B (top L), some 19 kilometres (12 miles) long, floating in the Ross Sea, near Antarctica. The monster iceberg nearly twice the size of Hong Kong island has been spotted drifting towards Australia in what scientists on December 9, 2009 called a once-in-a-century event.

This photo taken on November 5, 2009 and received on December 9, 2009 from the Australian Antarctic Division, courtesy of gsfc/NASA, shows a satellite image of iceberg B17B (C), some 19 kilometres (12 miles) long, floating southwest of the West Australian coast, between Australia and Antarctica. The monster iceberg nearly twice the size of Hong Kong island has been spotted drifting towards Australia in what scientists on December 9, 2009 called a once-in-a-century event

This image provided by Australian Antarctic Division shows a satellite view of the giant iceberg, fourth from right, named B17B which is moving towards Western Australia, according to a Tasmanian scientist. Glaciologist Neal Young of Australian Antarctic Division said the iceberg, known as B-17-B, was still largely intact and is currently 1700 kilometres south-south-west of the West Australian coast and moving north with the ocean current and prevailing wind. Its journey began almost 10 years ago when it broke away from the Ross ice shelf in Antarctica. Young said it was "very rare" to get such a big iceberg up at those sort of latitudes.

A helicopter carrying seven sightseers is dwarfed by the northernmost iceberg off Dunedin 16 November 2006. Two icebergs drifting off the New Zealand coast have attracted massive interest from sightseers as well as sparking fresh warnings to shipping after their 13,500 kilometre journey from Antarctica. The icebergs were about 100 kilometres (60 miles) off the Otago coast in the south-east of the country 15 November, the closest sighting off New Zealand for 75 years, The National Institute of Water and Atmospheric Research (NIWA) said

Australia's Prime Minister Kevin Rudd threatened legal action against Japan on Friday, Dec. 11, 2009, if it does not stop its research program that kills up to 1,000 whales a year.
