CO2 climate alarmism is based on two basic postulates concerning the effect of doubled concentration of atmospheric CO2 (compared to pre-industrial time):
- Radiative forcing of 4 W/m2
- Global heating of 1 C from radiative forcing of 4 W/m2.
- The IPCC might have outlived its usefulness. Let’s see what the next assessment report comes up with. But we are getting diminishing returns from these assessments, and they take up an enormous amount of scientists’ time.
