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.

It's in the Bible

Global Warming/Climate shift, no matter what you call it, the Bible clearly tells us the earth will get warmer. The Bible also tells us that before the flood, the earth was always warm, plus because of an addition expanse, it never rained until the flood. Reading the Bible is free, and many churches will provide you a free Bible by just asking.

Um, sorry. I do read the Bible. And it says nothing about the earth getting warmer. When referring to Armageddon, it is prophetic not literal. While it does say it never rained before the Flood, I don't see how that has anything to do with this issue.

He is either being very sarcastic, or he is grossly misreading an old book. I'm going to say hes the former, I sure hope it's not the latter.

The bible also tells us that crustaceans are an abomination unto us and that the earth is 6000 years old.

Um, no sorry. The Bible doesn't say the earth is 6000 years old. All it says is that God created the universe in 6 days. The Bible uses terms we are familiar with, so a day is not a literal 24 hours. In fact, the Bible says that we are in the 7th day still. So how long a day is in this context is not known. The Bible doesn't tell how old the earth or the universe is. It just breaks down the order which God created things into something we can relate to.

Why don't we call the kettle black for a change seeing as it's black. Scientists have never had enough historical data to map any weather trends over a 30 to 40 yr period. They take measurements of this or that and hype it up as the only conclusion you can draw when they don't have a clue. They do this to get continued funding and donations, not for our benefit. In the 1970s when the winters were cold enough to constantly snow and ice over roads in Texas, they said it's a global cooling trend. How much BS will people listen to before they finally call it BS. I haven't believed the global warming idiots that gave the nobel peace prize to Al Gore for a global warming study since the whole global warming talk started in the early 90s. Take the time to read, research, go to different sources and so on, and quit listening to the absolute BS the media touts. It's not that hard.

Indeed the Earth will get much hotter until it's eventually consumed by the Sun when it becomes a red giant. So the bible is right, if in fact it says that, which I wouldn't know.

Interesting replies. Read Isaiah 51 and then this: http://www.grc.nasa.gov/WWW/K-12/airplane/thermo0....

The earth is getting onto balance, the way it was before the flood.
