2021 Weather, Climate and Catastrophe Insight At $105 billion, flooding was the costliest peril of 2021 on an economic loss basis. This was largely driven by the There were 50 individual billion-dollar natural disaster events in 2021, which was well above the average of 38 flooding events in Europe and China. These two events alone accounted for more than $75 billion in economic events dating to 2000. All but three were weather or climate-related events. The 50 events were lower than the losses. The Tropical Cyclone peril came second, despite Hurricane Ida incurring at least $75 billion in damage and 55 in 2020, which was the third-highest year on record. Please note that U.S. wildfires are treated as individual becoming the sixth costliest global tropical cyclone ever recorded. Other perils with above-median losses included events; there were three such events in 2021. The U.S. had a total of 23 billion-dollar events, the second year in Severe Weather, Winter Weather, Wildfire and Other, the latter driven by notable volcanic eruptions. a row with at least 20 such occurrences and only the third time on record (2017, 2020, 2021). For some years in the graphic below, tropical cyclone events in the Atlantic Basin resulted in billion-dollar losses in the U.S. and elsewhere in the Americas. Such occurrences are only tabulated once.
