From the research that I've heard (and you need to take it all with a grain of salt) is that we are seeing slightly more large scale hurricanes & rainfall then there has been in the last few hundred years, however it's about the same as the last time the Earth went through a warming period. Keep in mind though that we feel the effects of these disasters more now due to our overflowing population.
