CO2 is a lagging indicator, not a leading one. The warming oceans causes it's release into the atmosphere far more than burning fuel. The flip side, is that it's good for plants, and more CO2 makes their habitation better. To me, that's one of the silliest things (besides the drama of the polar ice caps melting and Water World happening for real) about this debate. It's not nearly the best greenhouse gas out there, and it likely lags warming. By the way, for all the talk about climate changes, this planet has gone through and come out of how many ice ages? The great lakes were formed after one in which our Tundra biome became more temperate melting all the glaciers. That warming happened thousands of years ago, long before man would have been able to affect the environment. That's another big problem I have with this discussion. We have well documented massive warming and cooling phases in our history that every accepts as fact, yet no one in this debate is willing to concede that this could just be part of a grand geo-cycle despite plenty of evidence indicating it's possible. Again, I have no problems with the idea that we should keep the earth clean, but this idea that we are the central cause of climate change is really nothing more than people pushing agenda for the wrong reasons. I'm not saying mankind could contribute in some way or that there isn't any kind of climate change, but I do think this problem is being manufactured more to the financial benefit of some than anything else... and sadly, we are just arrogant enough as a species to assume that this must be our fault in some way. By all means, keep the planet clean. It's a great idea. By all means, keep researching this and figuring it out, but please for the love of all things intelligent, take a step back and look at the big picture and figure out what caused warming/cooling periods that mankind couldn't have impacted before we start blaming this one on us.
