I really wish that both "sides" in the climate change "debate" could put away the hyperbole and come to grips with the fact that we need to live in some way approaching equilibrium with the various processes happening here on planet Earth. That's not just about co2 production. Even though there is unquestionably consensus among climate scientists that the rising co2 level IS significant, there are *many* other factors at play. It won't matter if we get the co2 situation under control, but still have high-levels of fresh water pollution and half-dead oceans.
We need to pollute less, period.
We need to dramatically increase our total energy efficiency, which can largely be achieved by picking the "low-hanging fruit" of building insulation, indoor daytime lighting and industrial energy usage. All three of these can be addressed (easily!) with incentives like rebates and tax credits -- granted that takes political will, which seems in short supply, but it's all there already, just waiting to happen: just (gradually) shift the subsidies currently granted to fossil fuel companies over to businesses and homeowners that are willing to make investments in long-term energy efficiency and savings, it just makes sense: since energy saving == money saving.
The reality is that our total energy usage is increasing, so the more we stretch it, the more comfortable humanity can be in the long term. We need to be building as many solar, wind, wave, thermal gradient and salinity gradient systems as we can, all the while earnestly studying the effects and operation of these systems, and discovering our mistakes and correcting them as we go. We need better fission reactor designs: meaning serious R&D and testing. We need better (and more!) energy storage systems. And probably most importantly we need to come up with new ideas for generating and storing energy. Life is not static, we can't just say "hey, this is good enough" -- we have to make it better! Life forms don't stop evolving just because they find a successful niche. They keep going, because there's always more pressure around the corner. As humans, we've insulated ourselves from a lot of pressures, but that's really an illusion, since all we can ever really do is make buffers. Everything remains interconnected and interdependent.
As Bunker Roy says: Decentralize, demystify! People should know that they CAN provide for themselves, but they have to understand how it all works.
We are squandering our resources: geological, biological, financial and (most importantly) human. We need to refine our entire way of doing things.
The oil and coal WILL run out someday. It might be 100 years or 1000 -- but we need to be thinking truly long term here. It would be nice to still have plenty of oil and coal left for other stuff when we finally stop having to burn it for fuel just to keep the lights on. It's amazingly useful, and we have a finite supply.
