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.

I will give 100$ to anyone who can explain this one too me too...

I have the same problem. I told my wife she has 60$ to spend on groceries and she comes home with a bill of 78$ but she SAVED money. And I respond, well I'm not sure what kind of math you learnt in that catholic school but 78$ is 18$ MORE then 60$ not 18$ Less which is what I would consider saving money...

The day I sleep on the couch is the day I set my bed on fire. You let a women kick you you out of bed then you got more issues then global warming. lol

I wouldn't go as far as MURDER because of a fight, but I tend to agree. Just get a King sized bed and if you have a fight, make a wall of clothes between you.

As long as I'm the one paying the bills I will never be sleeping on the couch. If she has a problem with that well, she's welcome to find another place to stay while she is pissed off. :)

Be a man guys.. come on lol

Is this before or after the registered customer and regular sales savings? There within might lay your issue. And 60 dollars? Seems a bit low, how many times do you and your wife go visit the grocery store.

Probably the same Cath school where the girls said they were virgins because they participated in only a certain kind of activity.
