The theory that "greenhouse gases" have a greater warming effect than other gases goes back to the 19th century. The idea that carbon dioxide emissions might lead to catastrophic warming was introduced by Carl Sagan in the 1960s. He was inspired by research on the atmosphere of Venus. Around 1978, the environmental movement decided to promote Sagan's theory. The movement was already advocating energy conservation and renewables as a response to the "energy crisis." That is to say, a desired political outcome was agreed upon and then a "scientific" justification was developed.

Proponents of the global warming theory advocate for conversion to electric vehicles without expanding the electric power grid, which can only be powered by coal-burning power plants, fossil fuel, or nuclear energy. So-called renewable energy sources, coal and wind, cannot provide enough electricity to recharge hundreds of millions of electric vehicles.
