Bloomberg BNA: New nuclear reactor technology such as NuScale Power LLC’s small modular reactors and government support for existing nuclear power plants won’t be enough to rescue the declining nuclear power industry, according to new research. “Right now, the cost of generating electricity from newly constructed nuclear plants is almost double the cost for power from a new natural gas combined-cycle plant,” “In the absence of a dramatic change in market conditions, political will, and substantial subsidies, there is virtually no chance that the United States will be able to undertake the construction of additional large LWR (light water reactor) power plants in the next several decades.”

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.

Don Bogard, radio-geochemistry, nuclear geochemistry, planetary science: Carbon (C) exchange rates among C reservoirs tend to be at equilibrium unless and until a significant environmental change disturbs that. A significant increase in atmospheric (Atmos) CO2 concentration over the past century has been such a disturbance, and as a consequence a large fraction of that growth in Atmos CO2 has manifested as new plant growth and to increased ocean C levels. Increased temperature over the past century (which mostly has only modestly affected the ocean) and any tendency for warmer surface ocean to degas more CO2, has been over-powered by higher Atmos CO2 shifting the chemical equilibrium toward more dissolution of Atmos CO2 into the oceans. Higher decay rates of soil biotic material caused by the increased temperatures may be a source of part of the Atmos CO2 increase over the past century. However, it is most unlikely that organic decay has been other than a minor source, especially in the past few decades when Atmos CO2 was growing most rapidly.

Bonne Posma, physicist, Andrew Kenny, physicist, mechanical engineer: It is interesting to note that previous CO2 alarmist, James Lovelock (originator of the Gaia hypothesis), reversed himself about 10 years ago and now supports increased use of fossil fuels to potentially help mitigate the effects of the next ice age. This action was also proposed in 1900 by the first proponent of CO2-linked global warming, Svante Arrhenius (Nobel Prize in Chemistry 1903).
