William Happer, Emeritus Professor of Physics, Steven Koonin, New York University, Center for Urban Science and Progress, Under Secretary for Science at U.S. Depart. of Energy in President Obama's administration, Richard Lindzen Emeritus Professor, MIT Department of Earth, Atmospheric, and Planetary Sciences: This is a tutorial on man-made global warming, man-made climate change for the U.S. District Court, Northern District of California, San Francisco Division. 1) The climate is always changing. 2) Human influences on the climate are a small (1%) perturbation to natural energy flows. 3) It is not possible to tell how much of the modest recent warming can be ascribed to human influences. 4) There have been no detrimental changes observed in the most salient climate variables and today's projections of future changes are highly uncertain.
Richard Lindzen is an atmospheric physicist, Emeritus Professor at MIT. An implausible conjecture backed by false evidence and repeated incessantly has become politically correct ‘knowledge,’ and is used to promote the overturn of industrial civilization. What we will be leaving our grandchildren is not a planet damaged by industrial progress, but a record of unfathomable silliness as well as a landscape degraded by rusting wind farms and decaying solar panel arrays. There is at least one positive aspect to the present situation. None of the proposed policies will have much impact on greenhouse gases. Thus we will continue to benefit from the one thing that can be clearly attributed to elevated carbon dioxide: namely, its effective role as a plant fertilizer, and reducer of the drought vulnerability of plants.

Richard Lindzen is an atmospheric physicist, Emeritus Professor at MIT. From 1983 until his retirement in 2013 he was Alfred P. Sloan Professor of Meteorology at MIT: Here are two statements that are completely agreed on by the IPCC. It is crucial to be aware of their implications. 1. A doubling of CO2, by itself, contributes only about 1C to greenhouse warming. 2. If one assumes all warming over the past century is due to anthropogenic greenhouse forcing, then the derived sensitivity of the climate to a doubling of CO2 is less than 1C. The notion that alarming warming is ‘settled science’ should be offensive to any sentient individual, though to be sure, the above is hardly emphasized by the IPCC.
