Your entire post takes for given that we have to use fossil fuels for our main energy source. This simply isn’t true. Swap the energy source, and we’re (for the most part) fine. That’s 80% of climate change. The rest is agricultural emissions from livestock (and rice?) and agricultural land use plus a bit for cement (although fully cured cement, which takes decades, actually reabsorbs the CO2 the limestone itself emitted in the calcining process). This narrative that climate change is just due to general human activity is entirely the narrative I’m seeking to attack. It’s false. It’s mainly (80%) the CO2 and methane emitted from fossil fuel usage. Switch to wind, solar, nuclear, hydro, geothermal, and you’ve basically solved the problem like we did with the ozone hole. The climate will start to heal. It really IS just a swap out like with the ozone hole. And we basically have the tech to do this. It just sometimes costs slightly more upfront. The industrialized countries can do this just fine, barely breaking a sweat. Switch the grid aggressively to solar and nuclear, require all new cars and trucks to be at least plug in hybrid and then pure electric. Switch iron reduction to hydrogen (already happening), heat pumps for heating, cement produced electrically, and we’re basically there (besides some mop up of agricultural and land use emissions from farming). We’re just not doing it. At least, not the speed we should.
