And aren't magic. Switching fully to renewables is probably both impossible (still require non-renewable materials to make) and requires lowering of living standards (unless you want to build a dyson swarm you need to stop growing your energy use, which pretty much means recession, because our economy is energy driven - and if you need a different economic system for a technological solution to work it's not really a technological solution, is it. Also renewables are still pretty annoying when it comes to matching your output to your supply, and not being able to turn your AC whenever you feel like it is already a lowering of living standard for the richest countries).

And while we wait for them to "solve" the problem, we're already likely past 1.5°C, even if we just stick to not starving, having water to drink, and not freezing during winters from tomorrow.
