Now here's some climate change

More than a decade ago, this ScienceDaily article reported some impressive climate change.

The evidence from the greenhouse gas bubbles indicates temperatures from the end of the Younger Dryas Period to the beginning of the Holocene some 12,500 years ago rose about 20 degrees Fahrenheit in a 50-year period in Antarctica, much of it in several major leaps lasting less than a decade.

Now that, ladies and gentlemen, is what Mama Nature can do; 20 degrees F in 50 years.  And it wasn't restricted to the Antarctic.  Similar changes happened in the Greenland according to the ice core data.

Here is the home of the Taylor Dome Ice Core Project.

UPDATE: I found a nice PNAS paper on Ice Core evidence of abrupt climate change.
