Say it ain’t so, Randi!
This is so disappointing: James Randi joins the ranks of the climate change denialists, and he does so on the basis of an extremely poor argument. I know, he’s a professional skeptic about everything, but skeptics must have some standard for evidence … a standard which the climatologists have reached, while the denialists have not. Here’s the core of Randi’s dissent from the scientific consensus.
I strongly suspect that The Petition Project may be valid. I base this on my admittedly rudimentary knowledge of the facts about planet Earth. This ball of hot rock and salt water spins on its axis and rotates about the Sun with the expected regularity, though we’re aware that lunar tides, solar wind, galactic space dust and geomagnetic storms have cooled the planet by about one centigrade degree in the past 150 years. The myriad of influences that act upon Earth are so many and so variable — though not capricious — that I believe we simply cannot formulate an equation into which we enter variables and come up with an answer. A living planet will continually belch, vibrate, fracture, and crumble a bit, and thus defeat an accurate equation. Please note that this my amateur opinion, based on probably insufficient data.
At least he’s self-aware enoughto realize that he has come to this conclusion on the basis of his personal ignorance. He has two main reasons otherwise to disagree with the idea of anthropogenic global warming.
