John Shanahan is a civil engineer and past president of Go Nuclear, Inc. and Environmentalists for Nuclear - USA: There is a titanic struggle over the topic of man-made global warming and man-made sea level rise. The struggle exists on five levels: a) among scientists who have a good knowledge of physics and chemistry related to carbon dioxide from fossil fuels and its role in the entire subject of atmospheric, ocean and land sciences, b) among politicians, c) among people who are determined to save the world from fossil fuels and man-made carbon dioxide, no matter the effects on humanity, d) among other scientists and engineers who claim to have the answers, d) among the public who have very little to no knowledge of atmospheric science, but nevertheless are sure they know the correct answers. A second important topic relates to advocates for nuclear energy who claim to have the answers. If they are wrong about man-made global warming, how can they be trusted with information about nuclear energy. The absolute truth will only come from nature in time. The question is, "How many big mistakes will humans make on this topic before the truth is fully known?

David Wojick, Committee For A Constructive Tomorrow, CFACT, Washington, D.C., Ph.D. Philosophy of Science and Mathematical Logic, B.Sc. Civil Engineering: I doubt the average customer will be excited about coughing up a billion dollars just so the greens can feel good by forcing use of solar energy. But the utility loves it because, as a regulated monopoly, the more money they spend the more guaranteed profit they make. I can see their stock price and executive salaries going up as a result. Simply put, this is battery trickery.

Viv Forbes, Executive Director of The Salt Bush Club, Australia: The media loves disaster stories – floods, cyclones, heat waves, droughts and fires - each one “the worst Evaaaah” (evaah since the last one). Each report of catastrophe is usually followed by a religious chant about “man-made global warming”. Pretending we can change global climate by waging a war on carbon dioxide is foolish and dangerous nonsense. When cyclones, floods, droughts and bushfires strike we need disaster-proof helipads, rail links, roads, bridges, water and electricity supply.

Michael Shellenberger, Founder - President of Environmental Progress: This is an excellent review of wind and solar energy. It doesn't work. Michael and his science advisor, James Hansen are determined to stop use of fossil fuels because of their convictions that they are causing catastrophic anthropogenic global warming. John Shanahan points out that this website has hundreds of articles on wind, solar and man-made global warming. Based on these articles, he concludes that the world needs fossil fuels far more than any possible problems with global warming they cause. The problems with stopping use of fossil fuels are tremendous, existential. Extreme environmental and man-made climate change alarmists are determined to save the world with their solutions. They are not the best persons to help the world. China is doing a far better job of helping millions out of poverty by using fossil fuels than extreme environmentalists like the Sierra Club, the Natural Resources Defense Council or James Hansen are doing by forcing stopping use of fossil fuels.
