I never said I thought it was impossible to screw with the climate. It'd be easy. Want a temperature decrease? Drop a few nukes in Siberia. That'd throw a ton of matter into the atmosphere, causing dramatic global cooling. Sure there'd be radiation poisoning to those who lived around there and global famine, but we'd solve that whole global warming thing for a few decades.
Bad solution there. But it would ACTUALLY have a significant cooling impact on global temps.
Switching to windmills (which have a huge carbon footprint in their manufacture) and solar (ditto, plus the whole poisoning China thing with harvesting rare earths) won't have any significant cooling impact, ever. Those "solutions" are bunk. Better to go whole-hog on fracking - natural gas burns much cleaner with minimal environmental negatives compared to its energy density. But then the same people who cry "global warming" cry "no fracking." The perfect is the enemy of the good.
In the end, I have faith in the species to adapt or to invent technologies that actually will be helpful. We're not there yet. Band-aid solutions in the short term are meaningless. So are gotcha-type articles about Exxon.
