Roger Pielke Jr on disaster trends:
A new peer-reviewed paper out this week by Alimonti and Mariani asks whether global disasters have increased. Their answer is that they have not (and if the name sounds familiar, it is the same Alimonti whose paper is being improperly retracted — more fresh info on that in the coming days).
As I read their paper today I noticed that the time series they reported from the EM-DAT database looked a bit different than that I had last explored and presented here at THB late last year. So today I downloaded the most recent data from EM-DAT, and indeed there has been some changes to the most recent three years, presumably due to late entries into the database (however I will enquire as all post-hoc dataset updates should be documented). EM-DAT has been funded since the late 1990s by the U.S. Agency for International Development.
Below is the updated time series of global hydrological, climatological and meteorological disasters in the EM-DAT database, along with the linear trend, over the period 2000 to 2022.
