Phil Brennan asserts in his June 9 Newsmax column that the Earth is "demonstrably cooling." As we've pointed out in Brennan's previous attempts to peddle this claim, the 11 warmest years on record occurred in the past 13 years, and most scientists believe the Earth remains in a warming trend.
Brennan also criticizes efforts to reduce "atmospheric levels of CO2 in the absurd belief that this benign gas necessary for plant health somehow causes global warming." In fact, as we've also noted, no one is claiming that carbon dioxide, in and of itself, is a pollutant, as Brennan suggests. Rather, scientists argue that excessive levels of CO2 in the atmosphere can have a polluting effect.
