Global warming caused by  by man. The weather has taken on a new character “as human-caused global warming takes place in the background.” Weather conditions have become more extreme, with a shift between severe, very hot, sometimes prolonged weather conditions and increasing humidity. According to the Intergovernmental Panel on Climate Change, climate change has far-reaching negative effects. For nature and people. Kirchengast says: "It must be clear to everyone that in 2023 we will live in a world where storms will occur with such force that even an elderly grandmother will say: 'I have never seen that before.'" "From the perspective of climate physics, it is clear that climate change has never existed in such a pronounced form." The only effective long-term measure to limit these effects “is actually climate protection, reducing emissions.” (Catherine May)
