Various folks have been trying to point out the connection between cosmic rays, cloud formation, and global temperature for years.
There’s a reason why the device used to detect cosmic rays is called a “cloud chamber”.
Of course, I haven’t checked with Al Gore yet, so maybe we’re all missing something.
(By the way, a (probably *the*) major factor in determing the flux of cosmic rays impinging on the earth is solar activity, which modifies the magnetosphere that partially screens the earth from those cosmic rays)
The affects of cosmic rays actually magnify the affects of solar activity changes. When the sun is more active, less clouds form on the Earth, which allows more solar energy into the biosphere. When the sun is less active, more clouds form on the Earth, which allows less solar energy into the biosphere. So the sun is the dominate factor when you are talking climate change. Most of us already knew that anyway. The underlying science of this study, just magnifies the effects.
