       Watching a documentary from 1978, that tries to explain the many balances that make the biosphere on earth possible and keep our planet habitable. Of course the danger of human made climate change is already mentioned:https://www.zdf.de/dokumentation/dokumentation-sonstige/querschnitt-die-balance-der-biosphaere-100.htmlThe presenter is Hoimar v. Ditfurt a science journalist that manages to present a "holistic" perspective, without ever resorting to pseudoscience or anthropocentrism (https://en.wikipedia.org/wiki/Hoimar_von_Ditfurth)I miss people like that on current media.

       Simulating the greenhouse effect by setting up two tubes and filling one of them slowly with CO2, while heating both from above.Candles in the tube on the right will indicate how high the CO2 has filled up the tube.

       He closes the first of the two documentaries with foreshadowing the topic of the next, the danger to the climate balance, and with a remark that it looks like no one is going to act against it.
