JetStream is an “online weather school” hosted by the Southern Region Headquarters of the U.S. National Weather Service (part of the NOAA). Great idea – except one page reads used to read like something from Marc Morano or Ian Plimer, as discovered by Philip Machanick over at RealClimate.
Not only has the page in question contained misinformation since 2003, but someone inserted highly misleading statements about the temperature record in 2007, echoing a common contrarian confusion between the U.S. and global temperature record.
[Update, Nov. 3: The dubious CO2 lesson has been removed from the overall lesson plan, although it remains unchanged and no longer exists. It used to be #10 in the Atmosphere section, right after “Canned Heat”.
Update Nov. 11: The carbon dioxide lesson has been reinstated, with the previous misinformation removed from the discussion section.]
