So we should just hope this all away? That's a deeply childish viewpoint, and hoping is not a reliable plan. It will require many things: Carbon regulation plus geo-engineering plus improved power systems plus personal sacrifice. But where that starts is legislation. This is how we solved acid raid, the ozone layer, lead-based fuels and paints, and oh so many other environmental externalities. Individuals cannot solve this problem themselves. I could convert my house to solar and buy electric cars tomorrow and the problem is not solved, because I account personally (through my own choices) of only 20% of the issue. https://www.epa.gov/ghgemissions/sources-greenhouse-gas-emis...
