Three 9th-grade students met at the Zeiss Large Planetarium to discuss the topic of climate change. After a very interesting introduction in the dome hall of the building, they embarked on a rally to learn about different organizations that deal with various aspects of climate change (e.g., kosmos b). This was followed by three different keynote speeches on the stage of the dome hall. Dr. Romanovska from the Potsdam Institute for Climate Impact Research presented the latest findings on climate change data, Nicholas Omonuk, an activist from Uganda for Fridays for Future MAPA, reported on the concrete consequences of climate change in his village and for his community, and the Kipppunkte Kollektiv highlighted various ways in which young people can take action against climate change. After a lunch break, there was a panel discussion with local politicians to discuss specifically how Berlin can shape a climate-friendly future. The day culminated in a workshop on fake news on the topic. Many thanks to Ruby, Abigail, and Roxanne for participating in the conference!
