Past studies have shown that sunspot numbers correspond to warming or cooling trends. The twentieth century has featured heightened activity, indicating a warming trend.  (Source: Wikimedia Commons)

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 1.4 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.

But your only comparing money spending now and not damages done. That's like complaining Guy A is spending so much on car-repairs while Guy B is the one who made all the dents and scratches. The money wasn't lost when Guy A spent it on repairs, but when Guy B drove into those trees.

Meaning, you can't blame Obama for the damage control he has to do. After all, he got dropped in the middle of it all and wasn't the cause of it. You can however question his optional spending on things like future technologies, but that isn't the bulk of his spending.

I'm guessing you just watch CNN and MSLSD and drink it all in. Obama did not HAVE to support spending trillions. He wanted to. Our country would be far better off if absolutely nothing was done and the markets were just allowed to correct themselves over time naturally. That doesn't excuse Bush's actions either but one mistake does not mean another even larger one has to be made.

Obama was a member of Congress. Obama supported Freddie Mae and Fannie Mac and the lax regulation thereof. If Obama is not the cause then neither is anyone else.

Using your analogy Guy A bought the drinks for Guy B and encouraged him to race but since Guy B was driving, Guy A holds no responsibility according to you.
