While they do, 2025 was also the first year that the fraction of coal dropped in both China and India. In india it dropped by 3% and in China by 1.6%. So they build out fossil, but they build out non-coal power faster. China also hopes to peak coal in absolute terms by 2030. That's something at least.
Unfortunately, the environnement doesn't work with percentages but raw emissions

At least those show that a stratospheric injection doesn't persist for too long. 200 years of heightened volcanic activity was certainly a problem that eventually resolved itself.
The important, missing detail that breaks down this analogy is that we don't have a reference for a long period of vulcanism while anthropogenic emissions of greenhouse gases continue. This is where the "termination shock" issue comes in. Given current CO2 emission rates, a 50 year geoengineering strategy would mask an additional 100-125 ppm of CO2 added to the atmosphere. If the geoengineering scheme was suddenly st…

Yeah, stratospheric seeding is mostly a stopgap measure that needs to be used in conjunction with other geoengineering and political projects that strive to reduce/reverse CO2 emissions.
