All Antarctica seems to be warming, report says

The climate trend that is raising temperatures across most of the world is warming all of Antarctica despite earlier signs that most of the ice-covered continent has cooled during the past 50 years, researchers are reporting today.

The scientists stop short of claiming with certainty that wind-borne greenhouse gases from global industries on other continents are responsible for Antarctica's warming, but they say their evidence makes them "almost certain" that human activity carries at least some of the blame.

For years the Intergovernmental Panel on Climate Change, whose scientists track global warming year by year, has reported that greenhouse gases and global warming have clearly hit six of the world's seven continents, but that the evidence from Antarctica is still unclear. West Antarctica is known to be warming strongly, but the climate of the much larger eastern area was said to be cooling, some scientists have argued.

Now the issue has apparently been resolved.
