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.'
The behavior of a massive ice sheet that existed in northern Europe at the end of the last Ice Age has been outlined for the first time, and researchers believe it may provide a sneak preview of how major ice sheets in Greenland and Antarctica will act in the face of global warming.
OSU experts say those same forces are at work today, and probably mean that in the face of future global warming, the ice in large parts of Antarctica may actually increase, while the massive Greenland ice sheet -- which exists in a slightly warmer setting -- will almost certainly disappear.
These studies are confirming that the melting of ice sheets and their associated effects can be comparatively abrupt and rapid, the researchers said, once a certain level of warming is reached.
Hotter, Faster, Worser
Over the past several months, the normally restrained voice of science has taken on a distinct note of panic when it comes to global warming.
How did we go from debating the "uncertainty" behind climate science to near hysterical warnings from normally sober scientists about irrevocable and catastrophic consequences? Two reasons.
First, there hasn’t been any real uncertainty in the scientific community for more than a decade. An unholy alliance of key fossil fuel corporations and conservative politicians have waged a sophisticated and well-funded misinformation campaign to create doubt and controversy in the face of nearly universal scientific consensus. In this, they were aided and abetted by a press which loved controversy more than truth, and by the Bush administration, which has systematically tried to distort the science and silence and intimidate government scientists who sought to speak out on global warming.
But the second reason is that the scientific community failed to adequately anticipate and model several positive feedback loops that profoundly amplify the rate and extent of human-induced climate change. And in the case of global warming, positive feedback loops can have some very negative consequences. The plain fact is, we are fast approaching – and perhaps well past – several tipping points which would make global warming irreversible.

Just give me the botom line...how soon will there be very observable differences in South Alabama?

Hmphh. Nobody really cares.
... we're killing our planet and all everyone is talking about is war with Iran or war with this country or what if that country attacked the US. Shameful
