A lot of carbon emissions are coming from developing countries. They will not cut down since conservation would permanently relegate them to Third World countries.
Recycling doesn’t help. We need to reduce dependence on fossil fuels.
Fracking technology also makes it possible to get at enough quantities of natural gas in a short enough period of time to control the cost and availability of energy during this decade. We would expect other technologies to become available fifty or sixty years from now, but in the next ten years, the options come down to coal and gas.
Water will be another issue. Desalination tech is available but expensive.
