What Barack Obama says about climate change is just not so:, Dr. Tim Ball, Canada Free Press: 
Amid the rhetoric of President Obama’s speech to the United Nations September 22 conference on climate change in New York he repeated the same few points. They’re identical to those in Al Gore’s movie “An Inconvenient Truth.” Trouble is they are wrong. So, what is the President’s culpability? If he doesn’t know they’re wrong he and his advisors are incompetent. If they know, they’re deceiving.
Is it incompetence, or indifference to the truth?
