that is a very strong argument against us causing global warming. regardless, we need to be researching alternative energy sources or more efficient ways to use what we are using. i recall a press release in my environmental ethics course a few years ago, it was about 3m and their waste reduction. it's not about saving the environment, it's about "waste" which is just that, wasted resources that could be turned into profit.
And THAT is the reason to pursue and develop more "Earth Friendly" energy alternatives along with the whole, "Why give so much money to Bronze Age cultures that want to make the rest of us into a Bronze Age culture, too" thingy.
Still, though, we must be wary of our "experts". It is the government experts that assured that if we drilled only in deep water, we would be guarenteed that no oil spilled from a deep water well would ever reach shore. So much for the 'experts".
Responsibly pursuing clean energy and aggressively trying to free ouselves from the use of fossil fuels is a purely economic goal. Tying it to Global Warming is a swindle.
As an economic goal it makes sense and is supportable rationally.
As a method to avoid Global Warming, it's a snake oil solution to a problem that isn't a problem.
