In 2017 alone, sixteen $1 billion-plus weather- and climate-related events killed some 362 people in the US and cost the national economy $306 billion. This is a record for natual disasters and appears to be the shape of things to come. This represents 1.6% of the total US economy at a time when the economy is finely balanced between growth and recession.
The vast bulk of this damage was caused by hurricanes, with Hurricane Harvey alone costing the nation $125 billion. By comparison, wildfires only cost $18billion dollars.
2005 was previously the most expensive year with Hurricanes Katrina, Wilma and Rita racking up a total of $215 billion.
