I wrote a lengthy post but got all ranty and decided no-one needed to read that.

summary of my thoughts:

earth - temperature may change - doesn't matter. we either survive or not - in terms of damage to the earth, probably best if we don't survive, but either way we'll still be around in hundreds of years time.

kneejerk laws - are entirely crap and don't solve anything (cf banning incandescent lightbulbs and replacing with ones with a high mercury content! or banning liquids through security at airports!

politicians and greedy powerful corporations - should be burned. even if it does contribute to global warming. They do more damage to my world than pretty much anything else
