Study Recalculates New Greenhouse Effect Values & Sharply Minimizes CO2’s Contribution & Climate Sensitivity

Another study finds CO2’s greenhouse effect contribution and climate sensitivity are much smaller than claimed by the IPCC and proponents of anthropogenic global warming.

Ollila (2019) reconfigures the “consensus”-derived greenhouse effect radiation values and finds (a) LW absorption only adds 45% to Earth’s present atmospheric greenhouse effect, (b) water vapor dominates (76.4%) the total greenhouse effect whereas CO2’s contribution is minimal (7.3%), and (c) CO2 climate sensitivity is just 0.6°C upon doubling.

The reconfiguration eliminates the “physical contradiction” of having a 155.6 W/m² create an energy flux of 345.6 W/m² by rejecting the claim that the entire longwave energy flux is from greenhouse gases.

Further, CO2’s total temperature contribution to the greenhouse effect is reduced from 7.2°C to 2.4°C, which better aligns with the climate sensitivity (doubled CO2) estimate of 0.6°C.
