Today more interesting news National Center for Atmospheric Research (NCAR), has examined the last 100 years of data and had debunked the man-made climate change proponents' claim that the Sun has nothing to do with global warm:
Sun-Caused Warming

Climate Change: A team of international scientists has finally figured out why sunspots have a dramatic effect on the weather. It shows the folly of fearing the SUV while dismissing that thermonuclear furnace in the sky.
Mankind once worshiped the sun. Now the world studiously ignores it as nations prepare to hammer out a successor to the failed Kyoto Protocol, which expires in 2012, in Copenhagen in December. Something is indeed rotten in Denmark.
Our own government is committed to fighting climate change whether it be though Son of Kyoto or our own growth-capping, job-killing cap-and-trade legislation known as Waxman-Markey.
Despite the sun being the major source of all energy on earth, supporters of man-caused global warming have dismissed the sun's role in climate change. They say the historic 11-year solar cycle changes the amount of energy reaching the earth by about only 0.1% — not enough to account for temperature rises this century.
The Aug. 28 issue of the journal Science details how the scientific team led by the National Center for Atmospheric Research (NCAR), using a century's worth of data and three powerful computer models, figured out just how small changes in solar activity can trigger great changes in earth's climate.
The study found that chemicals in the stratosphere and sea surface temperatures during solar maximums act in a way that amplifies the sun's influence. The slight increase in solar energy in the peak production of sunspots is absorbed by stratospheric ozone, warming the air in the tropics where sunlight is most intense.
The additional energy also helps produce more ozone that absorbs even more solar energy. The increased sunlight causes a slight warming of ocean surface waters across the subtropical Pacific.
This stratospheric energy absorption and sea surface warming can intensify winds and rainfall, and ultimately influence global weather in ways that amplify the sun's influence.
"The sun, the stratosphere and the oceans are connected in ways that can influence such events as winter rainfall in North America," says study author Gerald Meehl. "Understanding the role of the solar cycle can provide added insight as scientists work toward predicting regional weather patterns for the next couple of decades."
The world has significantly cooled in the last decade, a period that corresponds to a decline and virtual halt in sunspot activity. Solar activity is in a valley right now, the deepest of the past century. The National Oceanic and Atmospheric Administration reports that in 2008 and 2009 the sun set Space Age records for low sunspot counts, weak solar wind and low solar radiance.
R. Timothy Patterson, professor of geology and director of the Ottawa-Carleton Geoscience Center of Canada's Carleton University, has said that "CO2 variations show little correlation with our planet's climate on long-, medium- and even short-time scales."
Rather, he says, "I and the first-class scientists I work with are consistently finding excellent correlations between the regular fluctuations of the sun and earthly climate. This is not surprising. The sun and the stars are the ultimate source of energy on this planet."
A Hoover Institution Study a few years back examined historical data and came to a similar conclusion. "The effects of solar activity and volcanoes are impossible to miss. Temperatures fluctuated exactly as expected, and the pattern was so clear that, statistically, the odds of the correlation existing by chance were less than one in 100," according to Hoover fellow Bruce Berkowitz.
Current solar inactivity is similar to what scientists call the Maunder Minimum, a period of solar inactivity from 1645 to 1715 that spawned what is known as the Little Ice Age. At Christmas, Londoners could ice skate on the frozen Thames and New Yorkers could walk over the Hudson from Manhattan to Staten Island.
The NCAR study shows how complicated atmospheric and climate science really is and how many variables must be factored in to have even a basic understanding of all the components that make up and influence earth's climate before the world commits economic suicide.

The number one cause of global warming...is the SUN?
That huge flaming ball of WHITE-HOT gasses out there?
Oh my gosh! Whoda thunk it?
