James Lovelock, PhD in Medicine, Chemist, Independent Scientist, Environmentalist. While working for NASA in the 1960s, concerned with detecting life on Mars he presented the Gaia hypothesis which proposes that living and non-living parts of the Earth form a complex interacting system that can be thought of as a single organism. He came to think that use of fossil fuels would produce catastrophic man-made global warming. In September 2017 he announced that he changed his mind. Environmentalism has gone too far; renewable energy is a disaster; the planet is not going to end any time soon; and, by the way, the answer is nuclear… When some man-made climate change Alarmists learn about Lovelock's new thinking, they dismiss him as being "old." With far less scientific credentials and accomplishments, they now claim to know a lot more about man-made global warming than does this outstanding scientist they once held in high esteem.That's how Alarmists Belief Systems go.
Three steps to a zero carbon world (by Bruno Comby, comments by Eric Jelinski, John Shanahan) France, Canada, USA18.Sep.2017
Bruno Comby, Nuclear Engineer, Founder - President of Environmentalists for Nuclear (International), EFN, in France presents views on decarbonizing the world and rapid global development of nuclear power. Eric Jelinski, President of EFN Canada and John Shanahan, President of EFN-USA present significant alternate views. Bruno Comby makes closing remarks. This is an example of how these topics are handled constructively in Environmentalists For Nuclear. In many other organizations and discussion groups, these divisive topics are extremely alienating. The world needs to learn to discuss differences instead of going to war with words or bullets.
Jay Lehr, Ph.D. Science Director at The Heartland Institute: The media has promoted unwarranted fear and unmitigated arrogance as to man's impact on his climate. While temperatures have fluctuated, today's Earth temperature is below the average for the past 5,000 years. 900,000 years of ice core temperature and carbon dioxide content records show that CO2 increases follow rather than lead increases in Earth temperature. This is logical because the oceans are the primary source of CO2, and they hold more CO2 when cool than when warm, so warming causes the oceans to release more CO2.
Douglas Lightfoot, Mechanical Engineer, Founder, Lightfoot Institute, http://www.thelightfootinstitute.ca: A new study by H. Douglas Lightfoot and Orval A. Mamer finds that the effect of carbon dioxide (CO2) on atmospheric temperature and climate is so small it is negligible. The study titled Back radiation versus carbon dioxide as the cause of climate change presents an original graph by the authors showing the concentration of water vapor plotted against back radiation. This is an important contribution to the discussion about CO2 because it allows an accurate comparison of the warming effect of water vapor with the known warming effect of CO2.
