The IPCC manufactures climate alarm by assuming CO2 controls water vapor to produce a runaway positive feedback system. Physicist Clive Best has posted his new paper showing that water vapor feedback is instead strongly negative, based on both the Faint Sun Paradox and a comparison of 5600 weather stations in the global CRUTEM4 temperature and humidity database. Peer-reviewed publications by Paltridge and others also find water vapor feedback is strongly negative. Without positive water vapor feedback, the IPCC's case for catastrophic man-made climate change collapses.
