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.

Yah, you are a couple days late on that one. Who are you, DailyTech?

Do we have an answer to the question? I haven’t seen anything from DT.

Seeing that MAndrews has posted follow-ups in this article since the question was raised, and the other articles with threads asking for clarification are still unanswered, I must conclude that DT doesn’t want to say.

I can’t fathom why. It’s kinda pissing me off. Are they just dicks? Is it too much to answer some basic questions about the people authoring this sites content?

maybe cause they dont really want you to know that its just someone else posing as a masher type to bring in more page views.

LOL for all we know, its jason mick roleplaying someone who can do more then copy/paste and add inflammatory headline.

Do we have a definitive answer for Michael Asher? Maybe someone from DT staff can clear this for us. I really enjoyed his articles.

I sent messages to Michael Asher and Daily Tech regarding his status. I never got a reply. Maybe there was some kind of flap between them?

It is really irritating not knowing, he was my favorite Daily Tech poster.
