I'm more worried about the banks than global warming.
I think a lot of this Global Warming hype is just another way to make us spend money.
You must have a new low emissions enviro friendly car etc. Never mind the impact to the environment and resources in manufacturing that new car. Not our problem though since it was probably built somewhere else. In my opinion keeping an old car well tuned and maintained will have a lot less impact on the environment than building a whole new one. Of course there's not a lot of profit in this for anyone and not a lot of extra income for the banks off the money you borrowed to buy the new fangled Toymota.
I've been doing a bit of reading on the history of world banking lately and it's very disturbing.
