The SUN, Not AGW, Is The Thing
The Greeks named the sun Helios, but the Romans used the name Sol, which is still in use today. Due to the important role the sun plays in our lives, it has been studied, perhaps, more than any other object in the universe, outside our own planet Earth.

The SUN, Not AGW, Is The Thing
Riding here on the Oblate Spheroid, it is easy to get lost in and amongst all the humanity and forget the connections to the natural cycles that have formed the orb we populate.
Take Climate Change (aka - Global Warming and Climate Stabilization), for example - many are putting forth a concept the the major influence on why the climate of this planet varies is related to human activity.
The hypothesis focuses upon the effects for accumulations of "Green House Gasses" as in CO2 ... the used air we exhale. In none of these calculations, however, do these people (many who look to control human behavior and profit off of business activity centered upon this control) take into account that plants take in CO2, and through osmosis give off Oxygen, and further, none of these hypothesis account for the largest functioning body in our specific solar system ... The SUN!

NASA Study Acknowledges Solar Cycle, Not Man, Responsible for Past Warming Report indicates solar cycle has been impacting Earth since the Industrial Revolution

Some researchers believe that the solar cycle influences global climate changes. They attribute recent warming trends to cyclic variation. Skeptics [read this as control profiteers], though, argue that there's little hard evidence of a solar hand in recent climate changes.
Now, a new research report from a surprising source may help to lay this skepticism to rest. A study from NASA’s Goddard Space Flight Center in Greenbelt, Maryland looking at climate data over the past century has concluded that solar variation has made a significant impact on the Earth's climate. The report concludes that evidence for climate changes based on solar radiation can be traced back as far as the Industrial Revolution.
Past research has shown that the sun goes through eleven year cycles. At the cycle's peak, solar activity occurring near sunspots is particularly intense, basking the Earth in solar heat. According to Robert Cahalan, a climatologist at the Goddard Space Flight Center, "Right now, we are in between major ice ages, in a period that has been called the Holocene."
Thomas Woods, solar scientist at the University of Colorado in Boulder concludes, "The fluctuations in the solar cycle impacts Earth's global temperature by about 0.1 degree Celsius, slightly hotter during solar maximum and cooler during solar minimum. The sun is currently at its minimum, and the next solar maximum is expected in 2012." According to the study, during periods of solar quiet, 1,361 watts per square meter of solar energy reaches Earth's outermost atmosphere. Periods of more intense activity brought 1.4 watts per square meter (0.1 percent) more energy.
The inconvertible fact, here is that even NASA's own study acknowledges that solar variation has caused climate change in the past. And even the study's members, mostly ardent supports of AGW [anthropogenic global warming] theory, acknowledge that the sun may play a significant role in future climate changes.
