Joe Biden might not have been lying when he said global warming was “caused by man”, but he was at best only partially right.
The globe has been warming for the last 20000 years or so: ever since the last ice sheet began to retreat, leaving Long Island, Martha’s Vineyard, Nantucket, Cape Cod, the Great Lakes and most of Canada behind — a process that’s still going on:
While there is plenty of evidence to support the belief that humans have contributed to global warming over the past couple hundred years, we’re talking about a phenomenon with a lot more geologic scope than that.
By the way, we’ve had seven ice ages in the last 650,000 years, and we’re probably in for another one after the current interglacial period passes. And by “we” I mean life forms. There’s no guarantee that humans will last that long.
