CLIMATE CHANGE: Ice Cores Reveal Green Arctic. “Analyses of sediment cores show that Arctic summers 3.6 million years ago were a good 8 degrees C warmer than they are today, and supported Douglas Fir and hemlock.”

Heck, during what used to be called the “climatic optimum” of around 5,000-6,000 BC we had trees growing on the shores of the Arctic Ocean, and inhabitants wore something that looked a lot like grass skirts.

And in a tangential note, if I were really rich I’d relocate some polar bears to the Antarctic, and some penguins to the Arctic, just to make life easier on future generations of schoolkids.
