Heat wave 2023: Weather experts warn of major problems in the south!
Just out of the fridge, you ask yourself: How can it be so hot in June this year? In the southern Baden area, temperatures regularly rose above the 30 degree mark. Climate researchers and weather experts are concerned: Loud Schwäbische.de June 2023 was the warmest Western Europe has ever experienced, with an average temperature of 20.49 degrees Celsius, an increase of 2.81 degrees above the 1991 to 2020 average. In parts of southern Europe it even felt like temperatures were up to 50 degrees Celsius, even up to 48 degrees in Portugal.
The extreme weather conditions are also contributing to worrying water levels in Lake Constance, whose level is currently only around 3.30 meters - one meter below the long-term average. Weather expert Roland Roth warns of problems for agriculture and forests, especially since there is no snow in the mountains as a source of water. However, there are also bright spots: Agriculture in southern Germany remains optimistic, thanks to the high quality of the soil in the foothills of the Alps. The concerns are more in the sandy regions, such as in eastern Germany, where the heat is particularly severe and inhibits grass growth. In Upper Swabia, on the other hand, there are no fears of crop failures.
Climate change and its consequences
But what is behind these extreme weather conditions? Spiegel.de shows that climate change will greatly transform Germany in the future - heat, floods and changing agricultural conditions are just some of the challenges. So we have to be prepared for more hot summers with temperatures over 30 or 35 degrees. Even 40 degrees cannot be ruled out, which can have serious consequences, especially for agriculture.
To clarify the connection between weather extremes and climate change, the EU climate service Copernicus refers to data from recent years. The ZDF today Report declares that 2024 was the hottest year on record. The east and southeast of Europe are particularly affected, while the west was blessed with rain. Here, too, there was heavy rainfall, which led to flooding; Germany and Austria were among those affected. These extreme conditions have affected over 400,000 people in Europe and have already claimed over 335 lives.
So there is huge pressure on the shoulders of decision-makers as the future of the climate for many regions is at stake. What will be the next steps? Anyone with a good hand will urgently need to find solutions to meet these challenges.
