I'm not so sure about the whole "Global Warming" thing and what causes it and how much we influence it. I think it is a natural thing that would have happened anyway, but that we are probably not helping by polluting our nice littel planet.
I do however support the whole campaign to make our civilization more "green". Oil lobbyists and their government cronies had and have far too much power and a lot of the "alternative" concepts were slowed or halted to make sure the Oil kept flowing and the cash kept rolling in.
Even now there is very little progress in the field of alternative energies. Hybrid concepts for cars and the move to Diesel instead of "normal" Petrol are not exactly solutions. They are just little "moves in the right direction" to match the new requirements the governments set. Hyrdogen power is pretty cool as a concept, but since it needs to be produced somewhere it just moves the problem around a bit. Nuclear energy is actually quite nice, but it has very different and unfortunately not very "green" side effects as well.
We really need to see a breakthrough soon, I have no idea how it could work, but I'm sure there are ways to do more than just reduce CO2 emmisions by a certain percentage...and I'm sure those ways won't lead us back to living on trees...
