Icy seas continue in Antarctica

Source: Reuters, Date: January , 2010

Sea water under an East Antarctic ice shelf showed no sign of higher temperatures despite fears of a thaw linked to global warming that could bring higher world ocean levels.Sensors lowered through three holes drilled in the Fimbul Ice Shelf showed the sea water is still around freezing and not at higher temperatures widely blamed for the break-up of 10 shelves on the Antarctic Peninsula, the most northerly part of the frozen continent.

The findings, a rare bit of good news after worrying signs in recent years of polar warming, adds a small bit to a puzzle about how Antarctica is responding to climate change, blamed largely on human use of fossil fuels.

Antarctica holds enough water to raise world sea levels by 57 meters (187 ft) if it ever all melted, so even tiny changes are a risk for low-lying coasts or cities from Beijing to New York.
