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.
Bill Nye the science guy. Will Happer, Emeritus Professor of Physics, Princeton University: “There’s this myth that’s developed around carbon dioxide that it’s a pollutant, but we exhale carbon dioxide with every breath. Each of us emits about two pounds of carbon dioxide a day, so are we polluting the planet?” Happer explained. “The 2016 Paris treaty will not do any good. Anyone who looks at the results of doing what the treaty says can see that the effect on the earth’s climate is — even if you take the alarmist computer models trivial — it will not make any difference and yet it will cause enormous harm to many people.”
Barack Obama, President of the United States: "Few challenges facing America and the world are more urgent than combating climate change. The science is beyond dispute and the facts are clear." "With all due respect Mr. President, that is not true." We, the undersigned scientists, maintain that the case for alarm regarding climate change is grossly overstated.
George Monbiot, author, writer for The Guardian: If our airports are full, there’s an immediate solution. Fly less. The Free Ride campaign has proposed a just means of achieving this: curb demand by taxing frequent flyers, but not those who seldom fly. (In case you’re wondering, I limit my flying to once every three years). But reason has taken flight, the moral compass spins, greed and desire soar towards the stratosphere, and our conscience vanishes in the clouds.
