Mike Wright is quite mistaken to think that the impact of carbon dioxide (CO2) on climate is well-understood [“Climate-change Denier Displays Lack of Scientific Understanding,” July 22, Xpress].
University of Western Ontario applied mathematician Dr. Chris Essex, an expert in the mathematical models that are the basis of the climate scare, 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.”
The Nongovernmental International Panel on Climate Change lists thousands of peer-reviewed science papers that show that much of what we thought we knew about CO2 and climate is wrong or highly debatable.
The lack of global warming for the past 18 years while CO2 rose 10 percent (likely due mainly to soaring hydrocarbon fuel use in China and other developing nations) suggests that there is something seriously wrong with the CO2-caused warming theory. As I showed the 1,500 students I taught at Carleton University here in Ottawa, Canada, the science is becoming more unsettled as the field advances. Not only can we not control global climate, we don’t even know if warming or cooling lies ahead.
Yet, on this flimsy basis, President Barack Obama wants to end America’s use of coal, your country’s least expensive and more plentiful power source, to supposedly “stop climate change.” It is worrisome for us here in Canada, and indeed across the free world, when our primary defender is bent on crippling itself in this way. U.S. Congressman Ryan Zinke (R-Mont.) summed up the situation well, “You don’t dismantle America’s power and energy on a maybe.”
