It wasn’t just Exxon that knew about climate change decades ago. But unlike Exxon, which not only denied it but used the foulest of propaganda tactics to confuse the public and delay progress, Shell made an accurate movie about it in 1991 to inform the public, called “Climate of Concern”.

Perhaps there is a parallel universe where Shell developed a sustainable business model, put Exxon out of business, and saved the Earth. Of course that is not the universe you and I are in right now.
