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”.

Craig Idso, CO2 Science: The Center for the Study of Carbon Dioxide and Global Change was created to disseminate factual reports and sound commentary on new developments in the world-wide scientific quest to determine the climatic and biological consequences of the ongoing rise in the air's CO2 content. The website has extensive articles and issues of CO Science going back to 1998.

The Coalition seeks to engage in an informed and dispassionate discussion of climate change, humans’ role in the climate system, the limitations of climate models, and the consequences of mandated reductions in CO2 emissions.

Sherwood Idso, Keith Idso, Craig Idso - There is considerable current concern that the ongoing rise in the air's CO2 content is causing a significant drop in the pH of the world's oceans in response to their absorption of a large fraction of each year's anthropogenic CO2 emissions. In light of these diverse and independent assessments of the two major aspects of the ocean acidification hypothesis -- a CO2-induced decline in oceanic pH that leads to a concomitant decrease in coral growth rate -- it would appear that the catastrophe conjured up by the world's climate alarmists is but a wonderful work of fiction.
