Today’s science class will be taught by Fox News. Today’s topic is: Global Warming. NSFB (not safe for brain)

Fox had an “expert” guest refute global warming via the first law of thermodynamics. Are they even trying anymore? Have they ever been trying?

It’s not clear what to conclude from this except that Fox and Bastardi are not familiar with the greenhouse effect. Climate scientists aren’t claiming that humans are creating energy. They’re saying that humans are trapping more energy by increasing the concentration of greenhouse gases in the atmosphere. Duke University scientist William Chameides, who called Fox’s claims “utter nonsense,” explained via email:

It is true that global warming requires a source of heat. In this case it comes from the sun. What CO2 does is trap a larger amount of the heat from the sun, preventing it from escaping and thus driving up temperatures. To argue otherwise is to argue that the greenhouse effect does not exist. In fact the existence of the greenhouse effect was established by scientists more than a century ago. It would be impossible to explain the temperatures of Mars and Venus, as well as the Earth, without invoking this effect. Bastardi went on to claim Le Chatelier’s Principle “says that any system in distress, physical or chemical in the atmosphere, tries to return toward normalcy. And that is why you’re seeing temperatures level off.”

In fact the notion of a system moving toward “normalcy,” or more accurately, toward a new “equilibrium,” explains why greenhouse gases do cause warming, rather than “Why CO2 Can’t Cause Warming.” By preventing infrared energy from efficiently escaping to space, increased greenhouse gases in the atmosphere make it more difficult for the earth to maintain its previous energy balance, and thus its previous temperature.

Also, here’s Al Gore losing his mind over the use of fake scientists to say that volcanos and sun spots are causing climate change. No really, he’s fucking mad as hell. As he should be:
