Kooks don’t need evidence

The other day, I mentioned the silly anti-global-warming argument of Alan Quist: he claims a 16th century map shows Antarctica in accurate detail, revealing that 500 years, the continent was completely ice-free. Therefore, he kookles, the world is currently in a deep freeze and a little warming would be good for us, and entirely tolerable.

John McKay takes a closer look at the old map. Would you believe it’s not so accurate after all? That in fact, it’s not even close?
