are you familiar with the experiments done in the New Mexico desert with SO2 and the supercomputer simulations that show a 1C - 2C drop in temperature (but also a change in rainfall patterns.) The scientific community is divided on it, but the push to end fossil fuels really began a few decades too late and too slow to stave off the worst solutions without some human interference in the other direction. From what I've read, it's not an extremely expensive solution either and even nations like Indonesia will be participating (especially since island based nations have the most to lose with sea level rise.)
