This is hard, measurable, factual data and observations showing variations of solar energy received by the Earth to be the over-ridingly dominant factor controlling changes in global warming and climate change. Computer climate models used to generate the myth of man-caused global warming are merely guesses based on (faulty) assumptions. Facts must outweigh guesses, always.

As the glaciological and tree ring evidence shows, climate change is a natural phenomenon that has occurred many times in the past, both with the magnitude as well as with the time rate of temperature change that have occurred in the recent decades. The following facts prove that the recent global warming is not man-made but is a natural phenomenon.
1. In the temperature trace of the past 10 000 years based on glaciological evidence, the recent decades have not displayed any anomalous behavior. In two-thirds of these 10,000 years, the mean temperature was even higher than today. Shortly before the last ice age the temperature in Greenland even increased by 15 degrees C in only 20 years. All of this without any man-made CO2 emission!
2. There is no direct connection between CO2 emission and climate warming. This is shown by the fact that these two physical quantities have displayed an entirely different temporal behavior in the past 150 years. Whereas the mean global temperature varied in a quasi-periodic manner, with a mean period of 70 years, the CO2 concentration has been increasing exponentially since the 1950’s. The sea level has been rising and the glaciers have been shortening practically linearly from 1850 onwards. Neither time trace showed any reaction to the sudden increase of hydrocarbon burning from the 1950’s onwards.
3. The hypothesis that the global warming of the past decades is man-made is based on the results of calculations with climate models in which the main influence on climate is not included. The most important climate driver (besides solar luminosity) comes from the interplay of solar activity, interplanetary magnetic field strength, cosmic radiation intensity, and cloud cover of the Earth atmosphere.

Solar Energy As The Cause Of Global Warming
Here is an excerpt from the ongoing debate on MSNBC's discussion board "climate change".

Head: the facts and evidence against CO2 being the main driver of climate are not "mine," but the findings of hundreds of peer-reviewed studies by scientists with the credentials to support their position. I'm quite certain that they are up to your "challenge."

The red curve illustrates the solar activity, which is generally increasing through over the past 100 years. At the same time, the Earth's average temperature as indicated by the black curve has increased by approximately 0.7C. (Reference: Friis-Christensen, E., and K. Lassen, Length of the solar cycle: An indicator of solar activity closely associated with climate, Science, 254, 698-700, 1991).
Matt: while we have only been directly observing changes in solar output for a few decades, there are thousands of years of historical records as well as geological proxies. Studies indicate that the sun has been hotter for the past 30 years than any time in the previous 10,000.
Sky: neither changes in solar brightness or CO2 can account for all of observed warming. This is why climate models use a positive feedback multiplier (an assumption that has never been identified) to achieve results consistent with observations. The Svensmark research has identified a mechanism for a positive solar feedback (greater solar output = fewer cooling clouds = additional warming), which will effectively shift some of this positive multiplier from CO2-based to solar-based. The more warming that is attributed to changes in TSI, the less that can be attributed to CO2.
The link between cloud cover changes and temperature is well documented.
