The rate of increase I last recall reported was ~2 ppm from 2017-2018. This would put 450 ppm in ~20 years.
2018-2019 for January is close to 3 ppm. This makes 450 ppm by about 2030.
If this rate of acceleration holds, the dominoes will fall quickly. If it increases, hold on. It will not be pretty.
