Some remarkable documents have emerged from major oil companies in recent years. Obviously, they have long been aware of the effects of greenhouse gases on the Earth’s climate. Still, it is shocking to see to what extent they understood the problem of global warming already in the 1980s. An internal report by Exxon from 1982 contains a forecast for the global average temperature of the Earth (cf. Shell and Exxon’s secret 1980s climate change warnings, The Guardian 2018-09-19).
I have allowed myself to add the actual development of the temperature (annual averages as red stars). Obviously, the Exxon scientists were correct. Faced with such evidence, the Exxon management took the decision not only to continue to sell oil, but also to use their economic power to influence the political and scientific process. Greed is not good!
