Euan Mearns, geologist: He takes a close look at the data on temperatures, carbon dioxide (CO2), and methane (CH4) found in the Vostok Ice Core of Antarctica. He focuses on the Eemian warm period between 130,000 and 115,000 years ago. This warm period was the last warm period before the current warm period, the Holocene. In her 2008 graphs showing the relationship between CO2 and temperatures from the Vostok Ice Core covering the entire record, Jo Nova stated the average lag was about 800 years, with temperatures rising (falling) about 800 years before CO2 rising (falling). This lag indicates that CO2 could not be the cause of rise or fall of temperatures.

Stephan Savarese, research engineer. President of Sauvons le Climat, Saving Our Planet: https://savingourplanet.net: Whatever the reasons for climate change, it's here and it's big. I name it Climate Transition because Climate Change has become a political issue. Showing pictures of isolated cold episodes in narrow regions of the world is picturesque, but cannot change the accurate, revised, precise statistics, which show that global warming has accelerated (at least) fourfold within the past fifty years, at a rate surprisingly fast and chaotic. As a consequence, ocean level rise, which had stabilized over the past five millennia at 1 mm/year, is on the verge of crossing the 5 mm/year mark, due to accelerated sea water thermal expansion, plus continental glacier melting.

F. Ward Whicker, Emeritus Professor in Department of Environmental and Radiological Health Sciences, Colorado State University. He has spent a lifetime out in the mountains of Colorado year round and also out in nature around the world. He presents his observations about changes in climate and ecosystems with conclusions that these changes are due to CO2 from use of fossil fuels.

Ed Berry, Physicist and Patric Moore, Environmentalist: They both consider that CO2 from human emissions is not causing serious man-made global warming, serious other climate change effects, nor serious rise in ocean levels. In this discussion, they debate which view, logic, reasons are correct for the conclusion that they share about CO2 from human emissions.
