Climate crisis, downpours, drought – that’s what the 12th Extreme Weather Congress in Hamburg is all about. Among other things, data on various climate aspects will be presented – such as temperature extremes.

The number of hot days in Germany with an air temperature of at least 30 degrees has increased significantly in recent decades. Averaged across Germany, it has tripled since the 1950s from around three days per year to currently an average of nine days per year, according to a paper on the state of the art that was published on Wednesday at the Extreme Weather Congress to be presented in Hamburg.

The mean number of ice days (daily maximum of the air temperature less than 0 degrees) decreased from 28 days to 19 days in the same period.

For example, on July 20 this year, during an intense heat wave in Hamburg– Neuwiedenthal measured a maximum daily temperature of 40.1 degrees. Temperatures above 40 degrees have never been measured so far north in Central Europe. In many regions there has been a massive accumulation of heat waves since the 1990s.

“This effect is a consequence of global warming and the associated Germany ensuing significant rise in temperature,” write the scientists in the paper, which was published by the congress and the German Weather Service. “With unrestrained greenhouse gas emissions, a further increase of five to ten hot days a year in northern Germany and ten to twenty hot days expected in southern Germany.”

The extreme weather congress takes place Wednesday to Friday in the International Maritime Museum in the Hanseatic city. Around 100 scientists and experts will present the latest findings, as organizer and meteorologist Frank Böttcher announced. Federal Environment Minister Steffi Lemke (Green Party), expedition researcher Arved Fuchs and Fridays for Future activist Luisa Neubauer are also expected.
