- There is no substantive basis for predictions of sizeable global warming due to observed increases in minor greenhouse gases such as carbon dioxide, methane, and chlorofluorocarbons. 
- Those who make the most outlandish claims of alarm are actually demonstrating skepticism of the very science they say supports them. It isn't just that the alarmists are trumpeting model results that we know must be wrong. It is that they are trumpeting catastrophes that couldn't happen even if the models were right ... 
- "Global mean temperatures have not changed to any extent that can be statistically confirmed for almost 10 years. The worst predictions in 1990 predicted a great deal more than was actually observed." (MSNBC)
