Ben Shapiro explains at National Review Online how some purported advocates of science deviate from basic scientific principles.

On Saturday, leftists around the nation took to the streets to sound off about their new religion: Science™! No, not testable hypotheses and well-constructed experiments. Science™! You know, like gay rights and abortion and global redistributionism and dying polar bears ’n’ stuff.

Leading the charge was eminent scientific revolutionary Bill Nye the Science Guy, a mechanical-engineering-degree holder who got famous as a children’s television presenter. Nye was a keynoter at the March for Science, where he stated, “We are marching today to remind people everywhere, our lawmakers especially, of the significance of science for our health and prosperity.” What sort of science was Nye standing up to defend? Budget increases for the Environmental Protection Agency and the National Institutes of Health, of course! He explained how all of this was scientific and not political: “Somewhere along the way, there has developed this idea that if you believe something hard enough, it’s as true as things discovered through the process of science. And I will say that’s objectively wrong.”

Belief isn’t science.

This is a good point. …

… This is the dirty little secret of the Left’s sudden embrace of Science™ — it’s not science they support, but religion. They support that which they believe but cannot prove and do not care about proving. Bill Nye isn’t interested in a scientific debate about global warming — how much is occurring, the measurement techniques at issue, the sensitivity of the climate to carbon emissions, the range of factors that affect the climate. He wants you to accept his version of the truth — not just that global warming is happening, but that massive government intervention is necessary in order to avert imminent global catastrophe.
