Errata as of July 20, 2010
On page 1, 3rd paragraph of the APA report, it says, “It explicitly covers six gases: CO2, methane (CH4), nitrous oxide (NO2), sulfur hexafluoride (SF6), and hydrofluorocarbons (HFCs).”  should read:

“It explicitly covers seven gases classified as greenhouse gases: CO2, methane (CH4), nitrous oxide (NO2), sulfur hexafluoride (SF6), hydrofluorocarbons (HFCs), perfluorocarbons (PFCs), and nitrogen trifluoride (NF3).”
