Climate models since the 1970s nailed it—most predicted global warming almost exactly as it happened.

It was not possible to be pro-nuke at that time with the corporate practices and technology of the 1970s. We still don't have real-world proof of inherently safe PWR/BWR reactor designs. That humanity mostly turned away from reactor tech is unfortunate but understandable after TMI and Chernobyl.

TMI: no casualties. Chernobyl: USSR design, nothing like it in western countries. An incident like many other industries. But both were used by environmentalists to spread fear. We have real world proof, you don't want to recognize it. Nuclear was and is the most safe industrial activity we have.

I saw some articles that suggested it might not be too bad. There would be a carbon dioxide layer reflecting heat from space and a lower carbon monoxide layer trapping heat from escaping to the atmosphere. With the success in reducing carbon monoxide pollution, that model is obviously redundant.

Earth's atmosphere reflects only 6% of incoming solar energy. The atmospheric reflectors for solar energy are mostly clouds, dust, aerosols, and some molecules like ozone. The contribution from CO₂ is virtually none; the reflection is almost entirely due to other atmospheric components.
