It really doesn't, when you have 7 billion people working hard to make the climate change as quickly as they can, and unfortunately we've already spent half a century knowing about the problem and doing nothing. The whole point is that we've changed major climatic change from a geological time frame to a human-scale time frame.
You'll see major upheaval as a result of climate change in your lifetime, and your children will see much worse.
The storm predictions, incidentally, are quite safe - no chance of them being wrong. Higher sea surface temperatures will absolutely lead to more frequent and violent storms; there's no chance at all of that not happening.
One to two generations is a long time.
I have listen to interviews with storm experts and it seems that they are not quite so sure about is then you. That said, it seems that compared to the world economy and what some people suggest, the damage from storms seems quite low.
The argument about eratic weather is not very good. I have heard multible storm experts say that they can really not model the overall changes. There might be more and bigger storms in one area but less in another. I really think that if anybody is pretending he can predict storm frequence in 50 years is just confirming their bias.
