According to a report from the Insurance Bureau of Canada, weather and climate related natural catastrophes are indeed on the increase around the world. 

Munich Re, an insurance company that specializes in climate change (see more here), defines a great natural catastrophe as any one or more of the following four situations: (1) number of fatalities exceeds 2,000; (2) number of homeless exceeds 200,000; (3) the country’s Gross Domestic Product (GDP) is severely hit; and/or (4) the country is dependent on international aid.  

This chart clearly shows an upward trend in the number of natural catastrophes - with the climate change related ones (shown in three shades of blue) as the main driver. 

According to the report, "Climate change is likely responsible, at least in part, for the rising frequency and severity of extreme weather events, such as floods, storms and droughts, since warmer temperatures tend to produce more violent weather patterns. As a result, weather events that used to happen once every 40 years are now happening once every six years in some regions in the country."
