The weather and climate disasters depicted above do not include Hurricane Harvey. The nine events above all happened this year and the economic cost of each event is $1,000,000,000.00 at minimum.
The NOAA report (Billion-Dollar Weather and Climate Disasters: Overview) found that the average number of billion-dollar events during 1980-2016, was 5.5 events per year. When looking at more recent years, 2012-2016, the average jumps to 10.6 events per year. This is not normal. This is very expensive. The map above is not yet complete. We still have several months left in 2017. I wonder how many more billion-dollar disasters will be added to the map at the end of the year.
