Siiiigh. Major coastal metroplexes in US: New York-Newark Los Angeles-San Diego Houston San Francisco-San Jose Jacksonville Seattle...https://twitter.com/stealthygeek/status/901885696075542531 …
Just as a fermi calculation: say there are 50 major metropolitan areas in the US, and 4 extremes that can happen a year.

Extreme heat, extreme cold, disaster 1, disaster 2, where disaster = {earthquake, tornados, hurricane, flooding, volcano, etc.}
-
Then one expects two once-in-a-century events per year, and one once-in-a-millennium event every 5 years.
-
If the rate at which such events occur globally hasn't changed significantly over the last century then concern is likely overblown
-
The only research I am aware of on the subject concluded that there is no upward trend in disaster intensity, only value at risk.
-
eg: weather damage trends are entirely driven by economic expansion in threatened zones like coastlines.
