Global warming may not be the culprit after all when it comes to Artic changes

Climate data can be difficult to analyze. Take for instance global temperature changes. Whereas the Northern Hemisphere has been warming, the Southern half of the planet is cooling. While Antarctic Ice is at near-record levels, the Northern Pole is warming at an unprecedented pace-- much faster than global warming models predict.

A new study published in the journal Nature identified a possible cause for this discrepancy. It identifies a natural, cyclical flow of atmospheric energy around the Arctic Circle. A team of researchers, led by Rune Graversen of Stockholm University, conclude this energy flow may be responsible for the majority of recent Arctic warming.

The study specifically rules out global warming or albedo changes from snow and ice loss as the cause, due to the "vertical structure" of the warming ... the observed warming has been much too weak near the ground, and too high in the stratosphere and upper troposphere.

This study follows hot on the heels of research by NASA, which identified "unusual winds" for rapid Arctic ice retreat. The wind patterns, set up by atmospheric conditions from the Arctic Oscillation, began rapidly pushing ice into the Transpolar Drift Stream, a current which quickly sped the ice into warmer waters.

A second NASA team, using data from the the GRACE (Gravity Recovery and Climate Experiment) satellite, recently concluded that changes in the Arctic Oscillation were "mostly decadal in nature", rather than driven by global warming.

Yes, 'global warming' is the perfect scam.

If anything bad happens, they blame it on 'global warming.' Or they blame it on not doing exactly what they tell us to do. If things go well they say, 'look see we told you all this bad stuff was going to happen but since we warned you we saved you from certain ruin.'

At this point they could blatantly lie about some aspect of the climate and the ignorant masses will swallow it with delight.

It amazes me still of the arrogance to think we have such a hand in the alteration of the Earth's climate.

Well, many people are very arrogant when it comes down to it, in all honesty. They want to believe that they can cause everything and end everything, when the facts are that they cannot really change all that much on this world and they are usually fighting against nature.

Its arrogant to think you can, Its ignorant to think you can't bla bla bla. In the end I think we should find out what the effects of our actions are. Regardless of weather you believe they can or cannot be that big.
