I think I'm more mercenary than you, I believe it's all about keeping the money rolling in.
You make a good point about an ice age though, that wouldn't be good and we're due one soon. I never really got into the whole global warming argument but it made me laugh because it's not heat that's going to kill us, it's the cold :-)
I remember when it was called 'global warming' and everyone predicted by now we'd all be dead from heat, too hot for crops, most of the world starving to death... And when that didn't pan out they had to rebrand it as 'climate change' instead, so it could get hotter or colder.. (way to hedge your bets, lol).
Those people don't realise the sun could wipe us out in a second if the right conditions arose. Even a mini ice age would thin the herd considerably.
When everyone said it was too hot to grow crops, I would think "Uh, Canada. Siberia. A whole bunch of land we can't use right now but has great fertile soil."
Just watch the death toll next winter in countries not used to getting freezing weather.
