I like the last few points made which kind of say, ignore the question of whether global warming is real or not, man made or not. There are more immediate concerns that are more directly concerning to us as a species. Yeah sure, the planet can handle itself, it's survived numberous events in it's history capable of wiping out man or whatever the dominent species is at the time. Does that mean though that we should just say "Oh well, screw it then, if the planet can heal itself, then we need not change anything." This is essentially the position of people rejecting the man made global warming question. Just because the planet can heal itself does not mean man will survive in the process. Beyond that though is the fact that whether we're ultimately harming the planet we are most definately harming ourselves and if we want to stay around as long as possible then we need to change our ways.
The reason that we don't though is because it's not particularly profitable and the people that are most profitable with the status quo have not been forward thinking enough to remain profitable if we change. We already have the capability to do away with petroleum based energy. What we don't have though is the infrastructure to support it or the ability for everyone to afford the change and have the products of change still be profitable for the companies that make them. If the oil and coal industries had a safe, plentiful, renewable, cheap energy resource that could replace gas, coal and oil without needing to build a new infrastructure and without forcing everyone to have to buy new cars, electronics, homes, etc. Then you would see the coal and oil industry championing the cause of Global Warming in favor of changing to this new energy resource. That's not the case though and so you have these industries fighting the idea of Global Warming in favor of kicking the can down the road so that those in power today can keep making money, thier attitude is so what if life will be miserable or even disappear 100 years from now? They won't be around anymore to have to deal with it, so it's not their problem.
