Scientific Hokum and its Destructive Political Agenda
by JBS President Emeritus John F. McManus
The war on the use of available energy (coal, oil, and natural gas) not only continues, it received a huge boost at the recent United Nations Climate Summit in Paris.
The doomsayers who gathered in the “City of Light” decided that the world must be saved from certain calamity by markedly reducing the amount of carbon dioxide put into the air by burning fossil fuels. But the carbon dioxide resulting from such fuel burning happens to be well known among competent scientists as the “gas of life.” Simply stated, plants eat carbon dioxide. The more that’s available, the healthier and larger will be the trees and plants that humanity uses for food, building, and more.
Orange trees as part of an experiment to see the effects of elevated levels of carbon dioxide. The result? Plants grew three times larger and produced 10 times more fruit! Photo and charts from U.S. Dept. of Agriculture.
Several years ago, scientists at the U.S. Water Conservation Laboratory in Arizona conducted a remarkable experiment. They planted small orange trees side by side with each tree enveloped in a clear plastic container whose top was left open. Half of the trees were supplied with ambient air and the other half received air enriched with 300 parts per million of carbon dioxide. After four and a half years, the trees enriched with carbon dioxide grew three times larger – both above and below ground – than those exposed only to ambient air. Also, the trees receiving the carbon dioxide produced ten times more fruit than the nearby trees that didn’t receive the added carbon dioxide.
An experiment like that has undoubtedly been duplicated elsewhere. It demonstrates carbon dioxide’s value, not its supposed harm. But what the Arizona scientists showed was politically incorrect. Some even feared that publicizing the results of their work could lead to cancellation of their funding by the government. No one is supposed to conduct experiments that contradict politically correct conclusions.
