Sea ice around Antarctica has been increasing at a rate of 100,000sq km a decade since the 1970s, according to a landmark study to be published today.Marc Sheppard of American Thinker rightly observes:
The study by the British Antarctic Survey, published in the journal Geophysical Research Letters, says rather than melting as a result of global warming, Antarctica continues to expand.
The fact that Antarctic ice is still growing does not in itself prove that global warming is not happening. But the BAS says increased ice formation can be explained by another environmental concern, the hole in the ozone layer, which is affecting local weather conditions.
But the absence of an ice melt overall does put a further question mark over extreme claims that the world faces precipitous rises in sea levels because of the melting polar ice caps. . .
The BAS, which discovered the ozone hole in the mid-1980s, has drawn on data from international agencies, including Australia's three Antarctic bases.
BAS project leader John Turner told The Australian yesterday that cooling had been recorded at the Australian bases and elsewhere in east Antarctica. He said satellite images indicated the ozone layer had strengthened surface winds around Antarctica, deepening storms in the South Pacific area of the Southern Ocean. This had resulted in a greater flow of cold air over the Ross Sea, leading to more ice production.
While sea ice had been lost to the west of the Antarctic Peninsula, sea ice cover over the Ross Sea had increased.
Dr Turner said the research results indicated why the extensive melting of ice in the Arctic was not occurring in Antarctica.
"While there is increasing evidence that the loss of sea ice in the Arctic has occurred due to human activity, in the Antarctic, human influence through the ozone hole has had the reverse effect and resulted in more ice," he said. As the ozone hole repaired itself as a result of measures in place to reduce chlorofluorocarbons in the stratosphere, the cooling in Antarctica was expected to be reversed.
"We expect ozone levels to recover by the end of the century, and by then there is likely to be around one-third less Antarctic sea ice," Dr Turner said.
Outstanding play, that. . .(via Maggie's Farm)
The selfish actions that melt northern sea ice would do the same to southern sea ice were it not for yet another group of our selfish actions. What exquisite eco-perfection. . .
Of course, as with all things which dare stall the symptoms of the impending global warming doom predicted by their infallible climate models, this one too will be conveniently short-lived and therefore depicted to in no way preclude immediate and extreme action.
