I once heard a truck driver call in to a talk radio show to explain his theory that global warming is caused by a decay in the Earth’s orbit. The planet is gradually falling into the sun, which is why things are getting hotter, he said. This man was too uneducated about physics, cosmology, and climate science to realise how comically ill-informed he sounded. Actually, the writer is the one that's ill-informed. The Earth is constantly falling into the sun. We call that an orbit. Doesn't lead to the truck driver's conclusions, but the author of this should be ashamed.
