Harrison Schmitt. The scientific rationale behind the Environmental Protection Agency’s proposed massive intrusion into American life in the name of fighting climate change has no scientific or constitutional justification. This has no basis in observational science as has been discussed previously relative to climate history, temperature, and carbon dioxide.
In addition, oceans of the Earth play the dominant role in the perpetuation and mediation of naturally induced change of global climate.
Steven Koonin. The idea that "Climate science is settled" runs through today's popular and policy discussions. Unfortunately, that claim is misguided. It has not only distorted our public and policy debates on issues related to energy, greenhouse-gas emissions and the environment. But it also has inhibited the scientific and policy discussions that we need to have about our climate future.
Donald Rapp. Here is a very short summary of what the world needs to focus on to end the controversial discussions on the debate of manmade global warming. It is written by a scientist and engineer with decades of experience. We highly recommend it.
John Holdren. The claim that this topic (mankind's use of fossil fuel and related CO2) is “extremely polarizing” among scientists and engineers is preposterous. The only scientists and engineers who consider the human influence on global climate to be controversial are (a) those who have not delved into the evidence and (b) those who are blinded by ideology. The national academies of science of every major country in the world that has one are unanimous in the view that human interference in the global climate system is a reality. Here are recent quotes. For another viewpoint, see article by Donald Rapp posted under "Warmers" titled "Climate Change, The Real Issues.".)
