Al Gore is speaking at the RSA security conference in San Francisco this afternoon. But good luck finding out what he says: Reporters are banned from the event.Banning the press just makes it look like Gore has something to hide. Whereas he's only going to win this argument by following the tenets that global warming science has followed for the last three decades, and which science has followed for the last four centuries: complete and total openness. This is not the kind of debate you win by fooling the other side, or convincing them by subtle and complicated arguments -- this is a debate about fundamental facts and fundamental physics, and you win by not deviating from them. Indeed, the pro-global warming side is already winning by following exactly this path. Just keep it up. Yes, it might take 20 more years. It might take 5. But you're not going to win by manipulating the press coverage. Gore has a Nobel Prize. He has a unique platform. He should act like it, instead of acting like he has something to hide.
