Variations in global temperature over the last 100 years are well 
correlated to sunspot activity. Here is one theory I found in the literature:

Apparently it is solar sun-spot activity that indirectly alters the 
earth's albedo and causes  temperature variations, not carbon 
dioxide. Sun spots involve electromagnetic storms that interfere with 
the flux of cosmic protons that create charged condensation nuclei 
increasing cloud formation in the upper atmosphere. Clouds help cool 
the earth by reflecting away the sun's heat. Low levels of sun spots 
indicate that cosmic protons showers are hitting the ,atmosphere with 
little interference improving cloud formation. There is a shortage of 
sun spots now. so the Earth will probably be getting cooler for many years.

This has been suggested in the scientific literature and in some 
popular press articles but the carbon dioxide induced global warming 
myth has become tenacious doctrine by politicians and environmental 
activists. Meanwhile draconian measures to stop the use of 
carbonaceous fuels may seriously hinder business activities and hurt 
our economy.

Personally, I believe that nuclear power is hated or feared by the 
people in power in Washington now, so I don't expect any progress 
along those lines.
