Climate ‘scientists’ arbitrarily increase fictitious effects of CO2

Attention alarmists: the latest version of the world’s most widely used climate model arbitrarily increases the fictitious forcing from CO2 ‘back-radiation’ and non-existent positive-feedbacks from clouds by 25%, from a fallacious 3.2C to 4.0C per doubling of CO2.

The Evolution of Climate Sensitivity and Climate Feedbacks in the Community Atmosphere Model

A. Gettelman et al

Abstract: We use the major evolution of the National Center for Atmospheric Research (NCAR) Community Atmosphere Model (CAM) to diagnose climate feedbacks, understand how climate feedbacks change with different physical parameterizations, and identify the processes and regions that determine climate sensitivity. In the evolution of CAM from version 4 to version 5, the water vapor, temperature, surface albedo and lapse rate feedbacks are remarkably stable across changes to the physical parameterization suite. However, the climate sensitivity increases from 3.2K in CAM4 to 4.0K in CAM5. The difference is mostly due to (a) more positive cloud feedbacks and (b) higher CO2 radiative forcing in CAM5. The inter-model differences in cloud feedbacks are largest in the tropical trade cumulus regime and in the mid-latitude storm-tracks. The sub-tropical stratocumulus regions do not contribute strongly to climate feedbacks due to their small area coverage.

The FOIA has been helpful in exposing the faulty methodologies used by these warmists.
Theirs is an religion for sure, if ever there was one.
Just watching Al Gore on the 24 hour death by power point marathon was proof.

The left will dismiss this or claim the scientists were bought and paid for by big buisness…all while ignoring how their “experts” are bought and paid for.
