Wow, Mr. Cockburn thinks he has discovered a simple proof that humans can't be warming the Earth: the greenhouse effect doesn't exist because "a cooler body cannot warm a hotter body without compensation."

From this I also learn that is useless to put on a coat in the winter. My coat is cooler than my body, hence can not be warming me. And to think of all the money people spend on outerwear! This climate conspiracy keeps getting bigger and bigger...

Virtually every other statement Mr. Cockburn makes in this column shows about the same level of scientific accuracy as his discussion of thermodynamics.
