it is more important to change the causes of global warming

Ok... let's change it to... people who pick their nose in public cause global warming.

It's as good a cause as anything else.

(But I'm not a fanatic. I'm open to other suggestions.)

Man’s contribution to the greenhouse effect is 0.28%.

So, I’d say it’s that “Mother Nature” that needs looked into for causing the other 99.72% of global warming.
