Nature has a way of finding ballance even if we dont see how. For man to claim we have the ability on purpose or accident, short of nuclear war, to affect the climate in a good or bad way is the height of arrogance. Global warming has been around for about 15 years, before that, it was global cooling. Some people just need a looming catastropy to worry about. Ask yourslef this though. If the industrial revolution, which started 100+ years ago, is the cause of global warming, why have global co2 levels only gone up 3.5%. When a fire burns down a forest, new growth explodes to replace it. When a valcano makes a new island above sea level, life immediately creaps in and takes over. Nature finds ballance folks. That isnt a fact we can alter. If we launched every nuke we have, most people, plants animals would die, and for hundreds of years life would struggle under harsh global winter conditions. But eventually it would come back. Our global climate is in a constant state of flux.
