It should be obvious why the opponents of climate science demand a “debate.“ The classic stand-up debate format, with equal time for “each side,” favors liars. That’s because you can tell a lie in a tiny fraction of the time it takes to explain why it’s a lie. (Especially a lie that’s been told so many times already that it can be invoked with a word. “Climategate.”) The liar tells all the lies he can fit into his time, and there is no way the honest opponent can refute them all, much less make his own argument. These are public relations experts. You can bet they understand this problem well.
