Global warming... Is it caused by us humans, or is it simply out of our control? Could the source be solar rays as has been suggested?
I have long believed it was human CO2 emissions which was the main factor, but search as I might I found little conclusive evidence supporting this. Other than Al Gore's movie of course. And naturally loads and loads of newspaper articles and TV programs. But on the other hand, certain US senators - and certain websites asked Questions to which I had no answer. As I am not a climate researcher, I felt a little uncertain about what to believe.


So when I found this very thorough article by NewScientist I could finally feel relieved. Now I can say with certainty what is causing the warming of our globe. And it is neither cosmic rays nor sun spots.
We are looking at a man-made problem.
