We have no more ability to prevent climate change than King Canute had to stop the tide from rising. All the observational evidence is that  has a relatively small effect on temperature. Changes in the Earth’s temperature will continue to be dominated by natural causes, whether we increase  concentrations, by continuing to burn fossil fuels, or whether we permit a nightmarish police state to stop emissions ,and punish ‘deniers’ as some in the alarmist camp demand.
