February 15, 2016, was the beginning of a debate on man-made climate change between two well-known experts in the field, Princeton Professor of Physics Dr. William Happer and University of Melbourne Atmospheric Sciences Professor Dr. David Karoly, hosted by James Barham and his team at TheBestSchools.org. Both have been heavily involved in atmospheric research since the 1980s. Happer believes that burning fossil fuels will have a minimal effect on climate but a large benefit to plant life and humanity. Karoly believes the opposite. How certain is the conclusion by some scientists that burning fossil fuels will lead to a climate disaster? Only debates can ferret out their certainty or lack of it. Burning fossil fuels may cause some harm, but if we stop burning them, we will face certain harm. Which is worse? Debates educate the public, they are necessary. This is an in-depth look at both sides of the scientific debate between two prominent experts.
