Why is global warming such a political issue? The earth has warmed and cooled before without any even supposed human cause. The sun has cycles of increased and decreased energy output.

Likewise, the "ozone hole" wasn't dicovered until 1985. Who is to say, then, that it wasn't always there? Since it's largest recorded size in Sept 2000, it has been gradually shrinking. In 2004, it was about 25% smaller than in 2003. This also cycles.
I get sick of panic over things we have no control over.
