Andrew Kenny, physicist and mechanical engineer: This article discusses CO2 levels and global temperatures over the last 550 million years, roughly the period of multi-celled life. CO2 has averaged about 2,000 ppm over this time but with huge fluctuations. Temperatures by contrast have been remarkably steady except for three periods of cold (when there was ice at the poles) and a period of semi cold.
John Holdren was President Barack Obama's Science Advisor: In the 1970s he talked about serious man-made global cooling. Since then, he talks about serious man-made global warming. In 2016 they issued a document saying that they would/could reverse climate change. If the climate gets warmer, they would cool it down (by stopping use of fossil fuels) and if the climate gets cooler, they would warm it up. Nothing close to this has ever been done. Here, he talks about the perversity of scientists discussing the "settled science" of man-made global warming. This has tremendous consequences for the global economy and well being of people everywhere. May the red team - blue team man-made global warming discussions begin.
Alan Caruba, a CFACT adjunct policy analyst: Describing the role of the Sun, Australian geologist, Ian Plimer, said, “There is a big thermonuclear reactor in the sky that emits huge amounts of energy to the Earth…The Sun provides the energy for photosynthesis. The Sun is the bringer of life to Earth. If the Sun were more energetic the oceans would boil. If the Sun were less energetic the oceans would freeze and all life on Earth would be destroyed.” We don’t control the Sun. Or the climate. It controls us. Consider that the Sun has a diameter of 865,000 miles. The Earth’s diameter is 7,917.5 miles. Thus, the Sun’s diameter is 109 times greater than the Earth’s. Carbon dioxide is barely .04% of the Earth’s atmosphere. Reducing it as the U.S.-China agreement proposes would have zero effect on the Earth’s climate.
John Shanahan, civil engineer, President of Environmentalists for Nuclear - USA: In order to promote use of nuclear energy, it is necessary to understand how it fits in with other forms of energy, mainly fossil fuels. It is very likely that fossil fuels will be used until they are no longer economical to mine and extract from the earth. Fossil fuels produce H2O and CO2 as their main by-products. A debate rages whether CO2 from fossil fuels is causing irreversible, catastrophic global warming and many other severe weather phenomena. This website presents over 200 articles on all sides of this debate. Go to HOME and the main tab, ENVIRONMENT. This debate is important for nuclear power because we shouldn't use unsound scientific arguments about CO2 from fossil fuels. This article presents photos from around the world to help you decide on the current condition of Earth's climate and how it compares with the past. Is it good or bad? Is it getting seriously worse or not?
