[en] This summer, the chancellor question may have something to do with the federal election. But the really decisive and longer-term chancellor question concerns climate protection. Because of the Corona crisis, it has become a little quieter around the topic. The activist prodigy of yesteryear, "Fridays for Future" founder Greta Thunberg, has come of age, and an adult now rules in Washington, too. There are small and large climate conferences where the important players are finally sitting at the same table again, first and foremost China, the United States and Europe. We can therefore hope that the debate on climate change as a whole will gain in maturity. Also with regard to nuclear energy. Ten years ago, the reactor accident in Fukushima occurred, after which the black-yellow coalition in Germany withdrew the extension of the operating lives of nuclear power plants, which had been decided barely five months earlier, and sealed the complete nuclear phase-out by the end of 2022. Beyond commemorative days, the issue is also important because some governments and scientists see nuclear power as a means of combating global warming.
