If we stop burning fossil fuels today, we still have 400ppm & rising. How do you plan to mitigate the legacy carbon levels?
One idea is soil carbon sequestration using regenerative agricultural practices. This will provide jobs, clean food, healthy soil and carbon sequestration - all in a cost-effective manner.

According to scientists at NASA and Scripts Oceanographic Institute, if we stop burning fossil fuels today, we would not see a drop in carbon content in the atmosphere for the forseeable future. However, no one predicted a continued rise in CO2.
The unknown in this scenario is the burning of tropical rainforest which diminishes the earths capacity for natural sequestration of carbon. There are many parts to this puzzle and we will have to start addressing them all. Did you know that air conditioner fluid has 5000 times the global warming potential of CO2? Methane has 21 times the global warming potential. A lot of natural gas (90% methane) escapes from a fracking operation. There is a long list of substances that act as global warmers.
