We can't have the status quo and environmental conservatism together. A great deal of damage has been done and the trajectory is awful. I appreciate your optimism but I think climate change is only a slow moving problem in the tiny span of a human life. The chances that fusion is still 20 years away at the time civilization violently collapses seem decent to me.
Not to mention that if the problems created by climate change start costing lives and infrastructure, our ability to implement solutions dwindle as well. We need to have done the research and start on fixing the issues before populations and research facilities have been decimated or destroyed. The only reason we have the ability now to even think about colonizing mars and developing a new and unproven energy generation method is because we have such large societies where these things can eke out of the cracks.
The solutions to climate change already exists and the status quo can be preserved. For proof, you only have to compare the per capita carbon footprint different countries like Sweden, Switzerland and France to to the USA, which has similar GDP and ~1/3 the carbon footprint.
Alternatively, you can compare France to China, which has a greater CO2 footprint per capita, and half the GDP per capita.
I don’t think they are exporting more CO2 production than their GDP peers. For example, The USA has 3x the per capita CO2/GDP of France and the USA imports twice as much per capita from China. That is something I would like to learn more about tho if you have any resources.
