'Tipping Point': Pollution Soaring to Crisis Levels in Arctic
Researchers have uncovered compelling evidence that indicates Earth's most vulnerable regions - the North and South Poles - are poised on the brink of a climatic disaster.
The scientists, at an atmospheric monitoring station in the Norwegian territory of Svalbard, have found that levels of carbon dioxide in the atmosphere near the North Pole are now rising at an unprecedented pace.
In 1990 this key cause of global warming was rising at a rate of 1 part per million (ppm). Recently, that rate reached 2 ppm per year. Now, scientists at the Mount Zeppelin monitoring station have discovered it is rising at between 2.5 and 3 ppm.
'The fact that our data now show acceleration in the rise of carbon dioxide level is really a source for concern,' said Professor Johan Strom, of Stockholm University's department of applied environmental science, which runs the Mount Zeppelin station. 'The increase is also seen at other stations, but our Zeppelin data show the strongest increase'...
