News Just In: According to scientists the sun is not responsible for global warming; humans are responsible for global warming. Lets repeat that.
Humans are responsible for global warming.

The following are not responsible:
The Sun - (cosmic rays)
Cows (flatulence)
Madonna (as above)
Al Gore
Al Gore and Madonna
Spawn of Al Gore and Madonna
Butterflies (this might be true)

Worryingly though, the sun has cooled down over the past 20 years. Ah well, one set of problems at a time.
