Global Warming is Above Ground not Below?

Reuters (Oslo) report that tests show that the 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 water under the ice shelf is very close to the freezing point,” Ole Anders Noest of the Norwegian Polar Institute wrote in a statement after drilling through the Fimbul, which is between 250 meters and 400 meters (820-1,310 ft) thick.  “This situation seems to be stable, suggesting that the melting under the ice shelf does not increase,” he wrote of the first drilling cores.

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.  Last month, most nations agreed at a Copenhagen climate summit to limit any rise in world temperatures to below 2 Celsius above pre-industrial times. But they failed to set cuts in greenhouse gas emissions needed to achieve the goal.
