(Production of CFCs in now banned in most of the world, but because of their ozone destroying properties, not greenhouse properties.) (newscientist.com)
About 150 years ago, a physicist called John Tyndall used laboratory experiments to demonstrate the greenhouse properties of CO ₂ gas. (theconversation.com)
In the MIlankovitch cycles, temperature rise caused, and thus led, CO2 rise (CO2 being driven from the oceans), whereas since about 1850, the fossil fuel combustion driven CO2 rise from a base lower than the MIlankovitch peaks has in turn driven, and led, temperature rise due to the Greenhouse properties of CO2.
