Gonna have to say this, and it doesn't really bother me if I get flamed or what not...dunno wht i would though...but I digress.
Global Warming is a natural occurance, we've merely sped it up. All this bull about "reduce Co2 and help to prevent climate change" is as I've stated, bull.
It's easy to point the blame purely at humans and for the scared people to think "well, if I do (x) then It'll stop the weather troubles", but it won't.
There's been more then one Ice Age, and the Sahara has been an Ocean on more then one occassion.
Another thing is that regardless of what we do, all the "doomsday" crap that's been predicted will occur anyway because the planet is not purely spherical; it expands and contracts and, as alot of scientists have "discovered", the Earth had reached maximum expansion and started to contract again, causing all the plates to shift, the concentration of sun to increase as surface area gradually decreases and the icecaps to mash into each other, effectively creating a warm slurry...
So it's a good idea to be green; once the ice melts again there'll be less shit to clean up, but it's nothing to worry about cos there's nothing we can do about it.
