How Oil Companies Hid the Truth About Climate Change | Global Warming | Busines Documentary from 2017

Oil companies such as Exxon and Shell have been secretly financing scientific studies and campaigns which are talking down climate change and have been influencing the public debate for 60 years.
New documents prove that since 1957, these companies have known that burning fossil fuels changes the climate – their own, strictly secret research had revealed this. But the US oil companies did not only carry out research and then concealed their results. Since 1963, Exxon and Shell engineers have been using their knowledge about climate change to gear up for a warming planet: They built higher and sturdier oil rigs to compensate for rising sea levels and more severe storms. Pipelines in the Arctic were anchored more firmly because of the melting permafrost.
Smoke and Fumes is a documentary about the biggest cover-up in history, which lasted for 60 years and was only recently revealed.
