Stephen Moore writes in the Washington Times about a recent National Geographic article that criticized people who refuse to drink global warming alarmists’ Kool-Aid.

Ironically, National Geographic’s sermon on settled science could have hardly come at a more inopportune time. In recent months, leading scientists have reversed themselves and have admitted their expert findings and advice were wrong on eating fat. After decades of telling us not to do so, we now learn that fat can be good for your diet and for weight loss. What we all thought to be true based on the expert testimonies, turned out to be precisely the opposite of the truth. Oops.

Forty years ago the experts warned of a coming ice age, now they are absolutely certain the earth is warming — and some of the same “experts” were onboard both scares. National Geographic even acknowledges this inconvenient fact, but it explains that this somehow actually helps make the case for global warming. If a scientific theory isn’t refutable — i.e., warming and cooling both prove climate change — then how is it science?

The magazine is incredulous that so many skeptics “believe that climate activists are using the threat of global warming to attack the free market and industrial society generally.”

Wait. Climate change activists are using the issue as a means of attacking free-market capitalism. This past summer major environmental groups gathered in Venezuela to solve leading environmental problems like global warming, concluding: “The structural causes of climate change are linked to the current capitalist hegemonic system.”

How is it paranoia to believe that the climate change industry wants to shut down capitalism when the movement plainly states that this is its objective? And how can a movement be driven by science when its very agenda violates basic laws of economics? I am no scientist, but I’m highly skeptical of a movement whose first advice is to steer the U.S. economy off a cliff toward financial ruin.
