Nor are we allowed to make jokes about Rajendra Pachauri. I always love those experts who go on TV and say you can’t pronounce on this subject unless you’re a bona fide climatologist. Dr. Pachauri, the head honcho of the Intergovernmental Panel on Climate Change, is a graduate of the Indian Railways Institute of Mechanical and Electrical Engineering. He’s not a climatologist but a railroad engineer. So, if he ever avails himself of a free half-hour with a Copenhagen hooker, I’m sure, like the Bombay to Cochin express, he’ll pull out on time.
