With that caveat firmly in place, the number of deaths due to weather is troubling, and different parts of the world are getting hit with different types of weather troubles. The most common weather disaster is flooding, making up nearly half of the total events. But floods, while devastating, aren't nearly as deadly as storms, which were responsible for the deaths of 242,000 people, primarily in poorer countries. 138,000 of those deaths were attributable to a single cyclone that struck Myanmar in 2008. Heatwaves, on the other hand primarily affected wealthy countries, killing 148,000 people in 20 years, mostly in Europe, a continent not used to extreme heat.
