It's not that often that you happen accross a refutation of a creationist idea that also scewers an AGW denialist cannard...but there you go.

Bad Astronomer has one up now.

A while back, Mark and I were going 'round and 'round about AGW again.  I didn't actually have a lot of time right then, so I was just cutting and pasteing standard replies to the cannards he threw out from Gristmill...a place where they gather all the cannards together and give cursory and rudimentary answers to them to save people time.

Well, one of them was "The earth has been warmer!  There were palm trees in Antarctica!"

Implicit in this assertion is the idea that the earth was once warm enough for palm trees to grow at the south pole. 

But as BA points out...Antarctica was not always at the south pole.  In fact, parts of it were quite a ways north from there at one point, and it took significantly longer than 6,000 years for it to travel to it's current location.

 (Also implicit that since the earth has been warmer than it is now, the current unprecedented RATE of warming is unimportant, as is the accelleration of the rate.  Kind of like if you had water running into the bathtub at a greater rate than it can go out the drain, and someone worried about the tub over flowing and asked you to turn down the flow - it would be silly to point at the bathtub ring and declare that the tub would not overflow because it had been more full in the past.)

Anyway, here's some more denialist fun.  Let's not leave out the anti-vaxers!
