A lot of folks ask me what's going to happen with tropical cyclones or heat waves, etc with climate change. If you're not someone with any atmospheric science background, but want a single, easy few-page article to read, I'd recommend this one.
One of my advisors, Adam Sobel, gave me a copy of "Climate change, picturing the science", a coffee table book on climate change that he wrote a chapter for. His chapter on what we expect for extremes is very nice. Its honest about what we know or don't, and why, but it doesn't expect you to have thought much about the subject before. You can read it on google books here.
