Radiative Forcing of CO2
This post examines how radiative forcing depends on CO2 concentrations in the atmosphere. In CO2 greenhouse demystified, we calculated the effective emission height where “thermal” photons escape to space . This height depends on the lapse rate temperature and defines … Continue reading

Global exaggeration ?
I rather suspect that climate scientists have consciously or sub-consciously tended to exaggerate future scenarios in order to boost AGW in the public consciousness as the biggest single threat to mankind. On balance, it now seems far more likely that … Continue reading

Climate sensitivity reduces by ~20% if using the correct TSI value
The latest value of TSI is 1360.8 W/m^2 (ref. Kopp & Lean 2011) measured by SORCE TIM. This is considerably lower than the ~1367 W/m^2 based on previous data that is used in most GCM models, including GISS model II. This lower … Continue reading
