| Abstract: | This essay is a thought‐provoking laudatio of carbon dioxide. It shows, that this gas, albeit one of the causes of climate change, is an essential part of life on earth. The author tells the little known story of carbon dioxide and points on facts from science and from the history of science. Thus, he gives a three‐dimensional picture of this unique substance. Without being a “climate sceptic”, he criticises the common picture of CO2 as a reification. A couple of new didactic experiments on CO2, including an impressive and simple experiment on the greenhouse effect, are added. |
