"...climate models show big storms could get two to five per cent stronger and produce 10 per cent more intense rainfall by the end of the century if humans continue emitting large quantities of the greenhouse gases that drive the increase in global temperatures. He was a co-author of a 2010 report predicting that climate change will lead to fewer but stronger tropical storms.
He notes that a bigger factor in massive destruction from tropical storms in the past 15 years is the fact that the population living in coastal areas is doubling in the United States every 20 to 40 years — laying out more coastal property and infrastructure that the storms can ravage."

"Even a 10-per-cent increase in rainfall is very small in comparison." - cbcnews
