People around the world are being hit hard by Corona - nothing about this tragedy is positive. The emission of CO2 has decreased because in many places airplanes and factories have stood still. However, the amount of greenhouse gas in the atmosphere is not decreasing because so much CO2 has already accumulated there; it will last and stay there for thousands of years. Also, the stabilization of our climate cannot under any circumstances be achieved by a socially devastating reduction of our economy, as we can now observe in some places due to the pandemic. Rather, the solution must be a targeted transformation of our economy – towards clean technologies.
