Dry lab

Anthony Watts says that the greenhouse-effect lab experiment in Al Gore’s “Climate Reality Project” was faked. He charges that the video was bogus, and that the experiment could not be done the way the narrator (Bill Nye) claimed that it was. I find his evidence very compelling, especially for the former charge.

There’s no question that the greenhouse effect exists; Gore is on completely solid scientific footing for that at least. So why fake the experiment? I think the answer is pure showmanship. He wanted a very simple experiment to illustrate to the viewer how elementary the greenhouse effect is. Unfortunately, a legitimate demonstration of the greenhouse effect would be too complicated to serve the purpose. Rather than settle for reality, Gore preferred to fake the experiment.

POSTSCRIPT: Just to emphasize: Although this is a telling indication of Al Gore’s lack of honesty, it has no bearing on the global-warming debate. There’s no doubt that the greenhouse effect exists. We can calculate the direct effect of rising CO2 levels on the temperature of the Earth. That direct effect is modest. The real question is what happens next: Do the secondary effects amplify or counter the direct effects, and to what degree? It’s impossible to run an experiment, so no one knows.
