Weather disasters are striking the world four to five times more often and causing seven times more damage than in the 1970s, the United Nations weather agency reports.

But these disasters are killing far fewer people. In the 1970s and 1980s, they killed an average of about 170 people a day worldwide. In the 2010s, that dropped to about 40 per day, the World Meteorological Organization says in a report that looks at more than 11,000 weather disasters in the past half-century.

The report comes during a disaster-filled summer globally, including deadly floods in Germany and a heat wave in the Mediterranean, and with the United States simultaneously struck by powerful Hurricane Ida and an onslaught of drought-worsened wildfires.

“The good news is that we have been able to minimize the amount of casualties once we have started having growing amount of disasters: heatwaves, flooding events, drought, and especially … intense tropical storms like Ida, which has been hitting recently Louisiana and Mississippi in the United States,” Petteri Taalas, WMO’s secretary-general, tells a news conference.

“But the bad news is that the economic losses have been growing very rapidly and this growth is supposed to continue,” he adds. “We are going to see more climatic extremes because of climate change, and these negative trends in climate will continue for the coming decades.”

In the 1970s, the world averaged about 711 weather disasters a year, but from 2000 to 2009 that was up to 3,536 a year or nearly 10 a day, according to the report, which used data from the Centre for Research on the Epidemiology of Disasters in Belgium. The average number of yearly disasters dropped a bit in the 2010s to 3,165, the report says.

Most death and damage during 50 years of weather disasters came from storms, flooding and drought.
