CO2 Coalition, www.co2coalition.org: Mark Twain said, "It is not so much the things we don’t know that get us into trouble. Rather, the mischief is caused by things that we do know that ain’t so.” We “know” that carbon dioxide is “bad for the environment.” (In fact, it is a prerequisite for life.) We “know” that the level of carbon dioxide in the atmosphere is reaching historically dangerous levels. (In fact, we have, these past centuries, been living through a CO2 famine. We “know” that on the subject of climate change, the “science is settled”.
