    Nah. Humans aren’t remotely that powerful. We could detonate every nuke on the planet tomorrow and make human life impossible, but in 1000 years the conditions for life would be fine, just the large animals would be extinct. In 1 million years you wouldn’t even know it had happened u less you dug I to the geological record. And 1 million years is like the blink of an eye on the timescale of a planet.

    The life-cycle emissions from nuclear are better than PV, but it’s still not as good as wind or hydro. But the issue is that it’s massively front loaded - you have huge emissions during construction that are slowly undone over the decades of operation. But we can’t afford to ramp up emissions for the next 14+ years (both the emissions of building a nuclear plant, and the fact that the existing coal/gas plants will have to run for another 14 years). If you switch to renewables, you can reduce emissions this year, not in the 2050s.

    And there is absolutely no way you’re going to repurpose a fission plant into a fusion plant. They have basically nothing in common apart from the name.

    It’s too late to start new nuclear projects. The quickest Gen 3 reactor build in the US was 14 years. So starting now, you’re looking to finish near 2040. And for those 14 years of construction, you’re pumping huge amounts of CO2. Over its lifetime it will emit less CO2 than many other forms of power, but that’s too slow. We need to be reducing emissions now, not reducing emissions in the 2050s and beyond.
