Climate change is a constant. Has been since the begining of time.
Human infestation of the planet has increased the rate of release of CO2 and thus the planet is warming more than it might otherwise have done. BUT cars are only a part of the cause.
The CO2 released comes mostly from burning hydrocarbons and from intensive farming. The largest contributor to CO2 release from butrning hydrocarbons is electricity generation, according to the US EPA. Transport is a close second.
Another source (International Energy Agency)states Coal is responsible for 43% of carbon dioxide emissions from fuel combustion, 36% is produced by oil and 20% from natural gas. The UK is particularly bad, 70%+ of our electricity comes from hydrocarbon combustion. France is only 8.5% and Switzerland burns no hydrocarbons to produce electricity.
It is easier to attack the motor industry than do anything serious to generate green electricity. So that is what we get.
