Weapons of mass destruction

I recently read an article by John Hougton, a climatologist, wherein he compares global warming to a weapon of mass destruction. His claims are that the warming is causing the more and more freakish weather patterns. I'l be honest, I don't know much about the issue, nor have i formed an opinion either way.

The issue that I have isn't the idea that global warming is occuring, but what can realistically be done about it. As much as we like to thinkwe do, the united states does not run the world, and we can't force other countries to adhere to global environmental policy.

If anybody has a viable solution, please post and let me know.
