Climate change debatable

I agree with U.S. Energy Secretary Rick Perry’s comments in a recent article that it’s inappropriate to treat those who don’t believe climate science is settled as if they are Neanderthals. After all, many experts do not agree that we face a man-made climate crisis. The Nongovernmental International Panel on Climate Change lists thousands of peer-reviewed papers in leading science journals that show much of what we think we know about climate is either mistaken or highly debatable.

University of Western Ontario applied mathematician Chris Essex, an expert in mathematical models that underlie climate change concerns, explains, “Climate is one of the most challenging open problems in modern science. Some knowledgeable scientists believe that the climate problem can never be solved.”

Science progresses through vigorous debate and a welcoming of well-informed alternative perspectives. Perry is right to encourage such a discussion. I wish Canada’s politicians had such courage.
