Climate disasters in first half of 2025 costliest ever on record, research shows

LA wildfires and storms this year cost $101bn, new study by non-profit resurrecting work axed by Trump says

The first half of 2025 was the costliest on record for major disasters in the US, driven by huge wildfires in Los Angeles and storms that battered much of the rest of the country, according to a climate non-profit that has resurrected work axed by Donald Trump's administration that tracked the biggest disasters.

In the first six months of this year, 14 separate weather-related disasters that each caused at least $1bn in damage hit the US, the Climate Central group has calculated. In total, these events cost $101bn in damages - lost homes, businesses, highways and other infrastructure - a toll higher than any other first half of a year since records on this began in 1980.
