Just back from taking part in a fascinating BBC seminar on climate change, led off by Al Gore. The event was held under Chatham House rules, but (since he has made the joke elsewhere) I don’t think it is out of place to pass on Frank Luntz’s fascinating insight that exactly nine months after the alleged UFO landings in Roswell, New Mexico, in July 1947 – Al Gore was born. Nine months? Alien life forms? Is this the ultimate Inconvenient Truth?
