Here are my questions: In 1970, when environmentalists were making predictions of manmade global cooling and the threat of an ice age and millions of Americans starving to death, what kind of government policy should we have undertaken to prevent such a calamity? When Ehrlich predicted that England would not exist in the year 2000, what steps should the British Parliament have taken in 1970 to prevent such a dire outcome? In 1939, when the U.S. Department of the Interior warned that we only had oil supplies for another 13 years, what actions should President Roosevelt have taken? Finally, what makes us think that environmental alarmism is any more correct now that they have switched their tune to manmade global warming?

Here are a few facts: Over 95 percent of the greenhouse effect is the result of water vapor in Earth's atmosphere. Without the greenhouse effect, Earth's average temperature would be zero degrees Fahrenheit. Most climate change is a result of the orbital eccentricities of Earth and variations in the sun's output. On top of that, natural wetlands produce more greenhouse gas contributions annually than all human sources combined.
