Yes most people do not fully grasp the scale of the problem. Any way you attack it the scale is absurd making almost all solutions crazy. Getting the co2 back and putting it somewhere, ceasing all fossil fuel use, storing enough energy for wind and solar to work, all of these are trillion dollars scale global moonshot projects.

*but so its all of the energy/money/effort that goes into modern fossil fuel extraction and processing so it isn't fundamentally impossible*
