ScienceDaily (May 12, 2009) — With the U.S. Congress beginning to consider regulations on greenhouse gases, a troubling hypothesis about how the sun may impact global warming is finally laid to rest.
Carnegie Mellon University's Peter Adams along with Jeff Pierce from Dalhousie University in Halifax, Canada, have developed a model to test a controversial hypothesis that says changes in the sun are causing global warming.
The hypothesis they tested was that increased solar activity reduces cloudiness by changing cosmic rays. So, when clouds decrease, more sunlight is let in, causing the earth to warm. Some climate change skeptics have tried to use this hypothesis to suggest that greenhouse gases may not be the global warming culprits that most scientists agree they are.

How much more evidence do the skeptics need? I mean wasn't it proved by many many organizations already? But they always have to come up with new stupid ways how to question something that is already well-known. And then people like Mr. Adams and Mr. Pierce have to waste their time on proving the skeptics are wrong with their pointless assumptions when they could be focusing on finding solutions how to prevent the global warming.
Take care, Elli
