The History Channel is sometimes to the left but these programs (warming period when no ICE was in the North Atlantic and the grass grew great in Europe allowing great expansion of humankind) and the little ICE age when humankind lost about 1/3 or more of its people, are true and need to be viewed by all.
In the show about the Little Ice Age they talk about the warming cycles and heating cycles of the earth and then BOOM, GLOBAL WARMING is brought up. Its like they did not even watch their own show or they are required by law to bring up global warming.
