Technical Rating:

Dr. Lindzen and Dr. Choi use changes in out-going radiation as measured by the Earth Radiation Budget Experiment satellite to show that the climate sensitivity is much less than that assumed in climate models. Eleven climate models show changes in sea surface temperatures cause a reduction in outgoing radiation, but the real measurements show an increase in outgoing radiation. If measurements mattered in climate science, this would end the climate scare.

Technical Rating:

FoS Director Norm Kalmanovitch shows how scientists fabricated the CO2 forcing parameter used in climate models.

Technical Rating:

This technical paper compares the tropospheric temperature trends from 22 climate model simulations to observations in the tropics during the satellite era. Modeled temperature trends in the lower atmosphere in the tropics are 100% to 300% higher than observed, and, above 8 km, modeled and observed trends have opposite signs.

Technical Rating:

The authors examine the satellite temperature anomalies across latitude bands and determine that the maximum climate sensitivity from CO2 is less than the no-feedback sensitivity.

Technical Rating:

Dr. Spencer shows, using a new analysis of satellite data, that the climate sensitivity to CO2 is very low. A doubling of CO2 would cause about 0.5 Celsius temperature increase. Climate models have been built with natural climate variability as a guide, during which it has been assumed that observed temperature variability caused the observed cloud variability. But since causation also flows in the opposite direction (cloud variability causing temperature variability), the climate models have a built-in bias toward high climate sensitivity, and so they produce too much global warming.
