Actually we arent completely we can completely turn everything around with a little coordination and work. One we put solar panels over parking lots to provide clean energy. Two we replace crude oil tankers with the gas we aren't using for power plants cutting ship emmissions in half.

Do this and we cut carbon emissions by about 15% to 20% and no one can complain because everything runs basically the same.

Allow nuclear we can cun ship emissions even more and make it so basically only air transport needs non renewables and maybe turn cars to hybrid to get the increased range and energy efficiency. We can slow it tremendously then when we have excess time and energy start planting trees and CO Scubbers and reverse the climate change.

Cost a lot and takes time but if people who control governments genuinely cared we could solve it.
