National Geographic says that ancient seal remains reveal a warmer Antarctica.

The discovery, scientists say, is the first hard evidence for a warming period in the region between 2,300 and 1,100 years ago.

An earlier warming period, between 6,000 and 4,000 years ago, has been recognized by other researchers and is believed to have been widespread, at least throughout the Southern Hemisphere.

Global warming is real. But it isn’t because of human beings. It’s because of the globe.
