چکیده:
Belief in manmade “Global Warming”, now renamed “Climate Change”, has become a ruling conviction of the modern age. It provides funding and careers for large numbers of activists, bureaucrats, journalists, and politicians around the world. They assert that mankind is raising global temperatures dangerously by increasing carbon dioxide (CO2) in the air. But basic physics shows that CO2, a weak greenhouse gas, can never have an important effect on temperatures. Reliable data confirms this. A thousand years ago, during the worldwide Mediaeval Warm Period, temperatures were higher than now while CO2 was lower than now. There is no evidence that the slight warming of the 20th Century was not entirely natural, caused by changes in solar activity. In the last 18 years, while CO2 has increased, there has been no global warming. The earth faces many serious environmental problems, but manmade climate change from rising CO2 is not a threat at all.
