2. Your question includes presupposition that we should somehow "fight" global warming. I don't think this phenomena is dominantly anthropogenic. From what I read long time ago (before the global warming histeria) this is cyclic - periods of warmer climate intertwined with ice ages.
3. I would like less pollution and I'm in for reducing burning of fossil fuel. But I'm not in for hysterical/religious part of anti-global-warming movement.
