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, first tests showed yesterday.
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 in West Antarctica.
"The water under the ice shelf is very close to the freezing point," Ole Anders Noest of the Norwegian Polar Institute wrote after drilling through the Fimbul, which is between 250m and 400m 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. Read more.
