Climate change over geologic time is, Laughlin says, something the earth has done “on its own without asking anyone’s permission or explaining itself.” People can cause climate change, but major glacial episodes have occurred “at regular intervals of 100,000 years,” always “a slow, steady cooling followed by abrupt warming back to conditions similar to today’s.”
Six million years ago the Mediterranean dried up. Ninety million years ago there were alligators in the Arctic. Three hundred million years ago Northern Europe was a desert and coal formed in Antarctica. “One thing we know for sure,” Laughlin says about these convulsions, “is that people weren’t involved.”

The clause that set the Feds free. I'd be interested to see which of you that oppose an insurance mandate would be okay with medical marijuana at the state level? And likewise, which of you that support medical marijuana also oppose the expansive power of the national gov't that struck it down?
