Rapid Rebound Brings Ice Back to Levels from the 1980s.

An abnormally cool Arctic is seeing dramatic changes to ice levels.  In sharp contrast to the rapid melting seen last year, the amount of global sea ice has rebounded sharply and is now growing rapidly. The total amount of ice, which set a record low value last year, grew in October at the fastest pace since record-keeping began in 1979.

The actual amount of ice area varies seasonally from about 16 to 23 million square kilometers. However, the mean anomaly-- defined as the difference between the current area and the seasonally-adjusted average-- changes much slower, and generally varies by only 2-3 million square kilometers.

That anomaly had been negative, indicating ice loss, for most of the current decade and reached a historic low in 2007. The current value is again zero, indicating an amount of ice exactly equal to the global average from 1979-2000.

Bill Chapman, a researcher with the Arctic Climate Center at the University of Illinois, says the rapid increase is "no big deal". He says that, while the Arctic has certainly been colder in recent months, the long-term decrease is still ongoing. Chapman, who predicts that sea ice will soon stop growing, sees nothing in the recent data to contradict predictions of global warming.

Others aren't quite so sure. Dr. Patrick Michaels, Professor of Environmental Science at the University of Virginia, says he sees some "very odd" things occurring in recent years. Michaels, who is also a Senior Fellow with the Cato Institute, tells DailyTech that, while the behavior of the Arctic seems to agree with climate models predictions, the Southern Hemisphere can't be explained by current theory. "The models predict a warming ocean around Antarctica, so why would we see more sea ice?" Michaels adds that large areas of the Southern Pacific are showing cooling trends, an occurrence not anticipated by any current climate model.

On average, ice covers roughly 7% of the ocean surface of the planet. Sea ice is floating and therefore doesn't affect sea level like the ice anchored on bedrock in Antarctica or Greenland. However, research has indicated that the Antarctic continent -- which is on a long-term cooling trend -- has also been gaining ice in recent years.

The primary instrument for measuring sea ice today is the AMSR-E microwave radiometer, an instrument package aboard NASA's AQUA satellite. AQUA was launched in 2002, as part of NASA's Earth Observing System (EOS).

What the ...

I have been a longtime lurker here. This article, and its subsequent responses, have made me decide to create an account.

So with that, I ask this: What is wrong with some of you?

The election for the president of the USA .. is that what this is about?

The global warming theory?

Lets start out with the election, since many of you wish to discuss it...

In the election for the President of the United states, 2008, our president was chosen by the media. Now, I am not a far right zealot or in anyway a "hater" of the left. The fact remains, the media fawned over Obama, its moderators fawned over Obama, and the electorate elected him, largely in part of the unabashadley pro-Obama attitude of our liberal media... and by the way, there is no arguement.. the media here in the good old USA is liberal.

No one asked Obama a tough question... no one in the media, at least. Hell, even McCain didn't ask the dude a tough question. So, once again, we have proven that we, the people of the United States, will do whatever the hell we are told to do. This time, the majority of us were led by the media to embrace an inexperienced guy -- who by the way chose the biggest loud mouth leftie of all as his VP -- to lead us.

So now Obama will be in charge. Great. I wish the guy well, being he is my president, albeit I did not vote for him. I am no dissident.

That being said, we move on to global warming.

Are you kidding me? Does not the Earth go through phases, cycles and what not? To have a THEORY that global warming MAY exist is one thing, but to outright expunge it as FACT and we all need to stop it NOW is ludicrous. There is no hard evidence of global warming that I have read. All the "global warming" tirade has produced is an ex-Vice President making 100's of millions of dollars preaching to his own choir of far left treehugging sheep.

Let's stop trying to blame ONE person for the mess the USA is in. Its certainly a very great number of jerks that got us into this. George W. Bush is not responsible, Al Gore is not responsible, Sarah Palin is not responsible, and so the list goes. Its a huge number of people responsible for the mess we are in.

The biggest contributor, however, is the exceedingly liberal media.
