By linking the topics of mathematics and climate change, I want to inspire pupils, students from other disciplines and a general public for mathematics. That's why I offer I am co-organizing the thematic year mathematics and climate change. As well as courses and lectures as part of the school days, the Campus Day, the Children's University or the Science Night at the University of Magdeburg and the Science Night at the City Hall.
