NASA admits all previous warming trends caused by sun

I wonder what Al Gore’s rebuttal is going to sound like…
Under mounting pressure from scientists that reject the politically popularized man-made global warming and climate models—the Anthropogenic Global Warming (AGW) theory—the American space agency NASA has admitted that all past warming trends were driven by solar activity.
A victory for the man-made ‘global warming deniers’
As more scientists have joined the outcry over the politicization of Earth’s climate cycles—the current number exceeds 20,000—promoters of the AGW model have denounced the “global warming deniers” countering that little evidence supports the view that the sun is driving the observed warming trend.
Now, however, new study released from NASA’s Goddard Space Flight Center in Greenbelt, Maryland measuring the global temperature variance during the past 100 years has found the sun’s heat and variable cycles have indeed made a significant, measurable impact and greatly influenced Earth’s climate.
In fact, the influence extends as far back as the Industrial Revolution.
Goddard’s research shows that the solar cycle’s ups and downs directly affect the temperatures and long term climate. During solar minimum they discovered about 1.36 watts per square meter of solar energy hits Earth’s mesosphere; solar maximum escalates to 1.40 watts per square meter.
It’s well-known that the sun passes through cycles of 11-year and 22-year intensities. Currently, the sun is on the upswing towards solar maximum when sunspot activity and solar flares will peak. The height of the maximum is expected during 2012-2013.
Earth now cooling
After the current peak, NASA and other space agencies believe the sun will go unusually quiet for the next 30 years or more.
Another proverbial nail in the coffin for the AGW theory is the fact that the Earth has been cooling since 2007.
Despite the fact that certain NASA scientists keep clinging to AGW (those with the largest government grants tied into the theory), the model has been showed to be flawed and some heavyweights are weighing in against it including one of the world’s great paleoclimatologists.
George Kukla, 77, retired professor of paleoclimatology at Columbia University and researcher at the Lamont-Doherty Earth Observatory has stated categorically that “The only thing to worry about global warming is the damage that can be done by worrying. Why are some scientists worried? Perhaps because they feel that to stop worrying may mean to stop being paid.”
During a lengthy interview with Gelf Magazine, Kukla explained: “What is happening is very similar to the time 115,000 years ago, when the last glaciation started. It is difficult to comprehend, but it is really so: The last glacial was accompanied by the increase of a really averaged global mean surface temperature, alias global warming.
“What happened then was that the shifting sun warmed the tropics and cooled the Arctic and Antarctic. Because the tropics are so much larger than the poles, the area-weighted global mean temperature was increasing. But also increasing was the temperature difference between the oceans and the poles, the basic condition of polar ice growth. Believe it or not, the last glacial started with ‘global warming!’”
Far from warming, Kukla is warning everyone that will listen that the world is about to enter a new Ice Age.
