From the Al Gore testifying to Congress story:
Representative Joe Barton, the leading Republican on the House Energy and Commerce Committee, challenged global warming science as "uneven and evolving".
"You're not just off a little, you're totally wrong," he said of Mr Gore's conclusions that carbon dioxide emissions contribute to global warming.
Given that people like Barton, N Lawson (snr), Crichton et al must appreciate that there is consensus among climate scientists, it strikes me they can't be too worried about what later generations think of them. I'm a bit surprised they're not more concerned about their Historical Legacy.
