We cannot control weather and we definitely do not have equipment that is sophisticated enough to predict how a weather is going to change ( or not ). Nevertheless, global warning or not, do the right thing, recycle when you should, deforest only when you need to ( btw, it is called development by some people. Don't get me wrong,I ain't complaning about indoor plumbing here, I'm FOR development) and leave the rest to the world.
P.S. I believe that the world has survived 6 mass extinctions and it will survive humans.
