How many billion dollar disasters in 2021?

The NOAA Billion-Dollar Weather and Climate Disasters page keeps track of these events.

During 2021, there were 20 separate billion-dollar weather and climate disaster events across the United States. The total cost from these events of 2021 was $145.0 billion and is the third most costly year on record, behind 2017 and 2005. The total costs for the last five years ($742.1 billion) is more than one-third of the disaster cost total of the last 42-years (1980-2021), which exceeds $2.155 trillion (inflation-adjusted to 2021 dollars). This reflects a 5-year cost average of nearly $148.4 billion/year — a new record — as shown above by the black line.
