Howard Cork Hayden, Emeritus Physics Professor, University of Connecticut: This is a closing argument by Professor Hayden. The debate took place at Colorado State University - Pueblo on December 2, 2017. The other person in the debate was Professor Scott Denning of CSU - Fort Collins.

Howard Hayden, December 19, 2017: What, then, is the basis for saying CO2 causes warming? More CO2 causes more absorption of IR in the far wings of the spectrum, and pretty high in the atmosphere. That absorbed energy rapidly adds heat to the local air, and is generally not radiated back to the surface. The actual atmospheric processes cannot be ignored, and they are not simple as Scott Denning avers.

Cameron Petrie, archaeologist: With climate change in our own era becoming increasingly evident, it’s natural to wonder how our ancestors may have dealt with similar environmental circumstances. New research methods and technologies are able to shed light on climate patterns that took place thousands of years ago, giving us a new perspective on how cultures of the time coped with variable and changing environments. An article in Current Anthropology explores the dynamics of adaptation and resilience in the face of a diverse and varied environmental context, using the case study of South Asia’s Indus Civilization (c.3000-1300 BC).

Dennis Hedke, geophysicist: Are the world's coastal cities destined to be inundated as ice melts at the top and bottom of the planet, causing the oceans to rise? Climate alarmists argue this will be the case if policymakers do not adopt draconian measures to eliminate fossil fuels, especially coal, which produce carbon dioxide emissions that, they allege, cause harmful global warming.

Calvin Beisner, Cornwall Alliance: From all appearances, the data-adjusters at PSMSL are attempting to “correct” the sea level rise data that do not support the conceptualization of a rapidly-rising sea level trend in response to rising human CO2 emissions. “It is always highly questionable to shift data collected in the far past without any proven new supporting material.” Apparently not even tide gauge measurements can be spared from those who tendentiously fiddle with raw data to satisfy an agenda. Alas, “A lie can travel halfway around the world while the truth is putting on its shoes,” as Mark Twain is (almost surely mistakenly) alleged to have said. Give this truth a little shove, and maybe it’ll catch and slay the lie.

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.

Reuters, John Ndiso: If current pollution rates continue, there will be more plastic in the sea than fish by 2050, said the United Nations Environment Programme (UNEP). Eight million tonnes of plastic - bottles, packaging and other waste - are dumped into the ocean every year, killing marine life and entering the human food chain, UNEP added. “Let’s abolish products that we do not need ... if you go to tourist places like Bali, a huge amount of the plastic picked from the oceans are actually straws.”

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.
