Even worse than we thought ™. Despite a recent sanity test study which demonstrated that high end climate models hindcast impossible Eocene temperatures, climate scientists are pushing ahead anyway with their new, even more extreme climate projections.
Within the last few years, over 50 papers have been added to our compilation of scientific studies that find the climate’s sensitivity to doubled CO2 (280 ppm to 560 ppm) ranges from <0 to 1°C. When no quantification is provided, words like “negligible” are used to describe CO2’s effect on the climate. The list has now reached 106 scientific papers.
