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, 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 1.3 watts per square meter (0.1 percent) more energy.

While the NASA study acknowledged the sun's influence on warming and cooling patterns, it then went badly off the tracks. Ignoring its own evidence, it returned to an argument that man had replaced the sun as the cause current warming patterns. Like many studies, this conclusion was based less on hard data and more on questionable correlations and inaccurate modeling techniques.

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 theory, acknowledge that the sun may play a significant role in future climate changes.

Only since then, hmm?

Cue the denier deniers.

Wait a few weeks. They will trash him until he is asked to recant, "revise" or "expand" his conclusions.

This is probably why the environmental inner circle has changed "global warming" to "climate change".

You can't go around collecting guilt and funding and have your paradigm change with new research.

This reseacher this author trashes and misquotes is showing the solar variation accounts for +.1 to -.1 temp variation in earth's temps (considerably less than what we are experiencing). Its an absurd and utterly untrue assertion that it supposedly "goes off the rails" or has any other problems with the fact that the majority of earth's larger temperature changes are caused by OTHER factors.

The author is simply twisting a partial presentation of the science to give more sound bites to Deniers to quote to each other with superior smirks, while never bothering to read the sources these propagandists are perverting.

Carry on. But try harder. It only took about 10 minutes to find the lies and misrepresentations in this piece. :re: The Denier efforts are looking a little pathetic.
