In regard to Mr. Ivey’s letter to the editor [“Climate-change Believers Betray Their Naiveté,” July 8, Xpress], there are two sides to brainwashing. It takes more than saying “CO2 is not now causing and never has caused the Earth’s atmosphere to warm” to debunk the “myth” of climate change. A good place to get scientific information on climate change [is the following site that] interested readers might find [to be] useful: realclimate.org.

Water is the most abundant greenhouse gas, and CO2 is next , but the “effectiveness” of these gases is the subject of much debate. The [following] site gives the history of changes in deriving these forcing functions: http://avl.mx/1cg
An interesting person in this debate is Dr. Murry Salby (Google him ) who is very active on The Hockey Schtick site (hockeyschtick.blogspot.com )
