The science is settled - Global Warming

The climate of our planet is variable. It has been much warmer and much colder than it is now and there is precious little that we can do to stop it. The only thing a Carbon Tax will do is make some people even more rich.

Case in point from Live Science:

50-Million-Year-Old Redwood Chunk Found in Diamond Mine
A search for diamonds in Canada's far north turned up a rare fossil — a chunk of a redwood sealed in volcanic rock more than 50 million years ago.

A study of the well-preserved specimen, which also contains a sliver of amber, shows that the now-icy region where it was found had a swampier past.

The wood was found a few years ago in a kimberlite pipe, named the Panda pipe, over 1,000 feet (315 meters) below Earth's surface at the Ekati diamond mine, just south of the Arctic Circle in Canada's Northwest Territories, the researchers say. A kimberlite pipe, a type of volcanic pipe, forms when kimberlite magma pushes through deep fractures in the Earth's crust to create a vertical tubelike structure that's wider at the top like a carrot. Kimberlites have the deepest origins of all magmas on Earth and when they cool, they leave behind rocks dense in crystals, sometimes holding diamonds.

The researchers, who report their findings in a Sept. 19 paper in the journal PLoS ONE, say the site of the Panda pipe was covered with a forest of Metasequoia, similar to today's dawn redwoods, during the early Eocene. The kimberlite eruption that occurred there about 53.3 million years ago opened a hole in the Earth's surface, sucking in some of those redwoods. Lead author of the study Alex Wolfe of the University of Alberta explained that open space along the side of this hole allowed the trees to tumble far inside. "Then it cooled, and the wood was locked in the volcanic rock," Wolfe told LiveScience in an email.

So basically, at one point, there were Sequoia Trees growing up in the Canadian Arctic. And the leading Climate Scientists are bloviating about a 0.2°C increase over the next 80 years and how this will destroy all life on Earth?
