Howard Cork Hayden, Emeritus Physics Professor, University of Connecticut: Part 1: Some Climate History, Part 2: IPCC et al, Part 3: Adding Heat to the Atmosphere. There is no evidence from a half-billion years that CO2 has ever controlled the climate. 40% of the world's 7 billion people have no access to clean drinking water. Three billion people cook over open fires - with deadly consequences. This was presented in a debate about man-made global warming at Colorado State University - Pueblo on December 2, 2017. The other person in the debate was Professor Scott Denning of CSU - Fort Collins. Use search box with Denning to find his presentation.

Steven Chu, U.S. Secretary of Eergy and Nobel Laureate: Climate change is real, and it’s happening now. “There is compelling evidence that Earth’s climate is changing and humans are responsible for it. We only have one chance at correcting it and we have to do it,” Chu presented decades of satellite data that show how human activities are affecting the global climate pattern. “Glacier melting is accelerating and the sea level is rising,” The good news is that new technological solutions are being developed in the area of air filtration using HEPA filters and novel techniques that trap particles using electric charge. He predicts the price of solar-generated electricity will continue to drop from 3 cents per kilowatt-hour in 2020 to 2 cents per kWh by 2035 or 2040.

Bryan Leyland, founding secretary and energy issues adviser for the International Climate Science Coalition (ICSC). Tom Harris is the ICSC’s executive director. Modern highly efficient coal-fired power plants with stack gas cleanup – the kind that can be built all over the world – are as clean as they can be. Their emissions consist of water, CO2 and nitrogen. The stack gas cleanup removes virtually all the real pollutants, especially sulphur dioxide and nitrous oxides.

Chris Mooney, Washington Post: The climate change simulations that best capture current planetary conditions are also the ones that predict the most dire levels of human-driven warming. Under a high warming scenario in which large emissions continue throughout the century, the models as a whole give a mean warming of 4.3 degrees Celsius (or 7.74 degrees Fahrenheit), plus or minus 0.7 degrees Celsius, for the period between 2081 and 2100. But the best models gave an answer of 4.8 degrees Celsius (8.64 degrees Fahrenheit), plus or minus 0.4 degrees Celsius. Overall, the change amounted to bumping up the projected warming by about 15 percent.
