Copper reserves are insufficient to manufacture even the first generation of EVs.[0] The decarbonized economy will require horses and bicycles (both net zero emissions). The good news is that reducing solar intensity by 2% would compensate for a doubling in CO2 levels, however (see Manabe and Wetherald 1975).[1,2] I hope governments will not wait too long to act. If a solar shield is not implemented within the next 20 to 30 years, the opportunity to do so may close as a result of generalized collapse.
