Warm Antarctica 11,000 B.C.

Science Daily: New Clue to How Last Ice Age Ended.

ScienceDaily (Sep. 8, 2010) — As the last ice age was ending, about 13,000 years ago, a final blast of cold hit Europe, and for a thousand years or more, it felt like the ice age had returned. But oddly, despite bitter cold winters in the north, Antarctica was heating up. For the two decades since ice core records revealed that Europe was cooling at the same time Antarctica was warming over this thousand-year period, scientists have looked for an explanation.

A new study in Nature brings them a step closer by establishing that New Zealand was also warming, indicating that the deep freeze up north, called the Younger Dryas for the white flower that grows near glaciers, bypassed much of the southern hemisphere.

"Glaciers in New Zealand receded dramatically at this time, suggesting that much of the southern hemisphere was warming with Antarctica," said study lead author, Michael Kaplan, a geochemist at Columbia University's Lamont-Doherty Earth Observatory. "Knowing that the Younger Dryas cooling in the northern hemisphere was not a global event brings us closer to understanding how Earth finally came out of the ice age."
The biting question I have is: who needs Lamont-Doherty Observatory when we have Homer, Herodotus, Plato, Plutarch, and Newton?

1 degree C

Break out the picnic baskets and inflate the volleyballs! Kids, we're Atlantis-bound!

Confirmation Bias is a bitch.

According to mainstream science, 1 degree C would cause a runaway Greenhouse Effect that would melt every glacier in Antarctica.
