My guess is that we are headed towards a period of reduced global economic activity from a variety of reasons. This could rapidly increase the average temperature .5 to 1 degree C from the reduced pollution and aerosol masking effect. Pollution has a lot of effects and cleaning up the air might eventually increase plant and plankton growth perhaps locking up more CO2 and stabilizing the temperature, I don't know - just my personal thought there. Things are changing very rapidly with polar ice melt and methane release also causing changes. !trdo
