I see that Fred Singer (and the Wall Street Journal) is copping a pasting for his column denying sea level rise could be a problem, which sounds so obviously amateurish, and kinda dumb, that people are really surprised it would be published, even by the WSJ.
Singer has been around forever, so I had to check his age. He's 93!
Richard Lindzin, the only AGW skeptic scientist who I think has been credited with at least being wrong in an interesting way, is now 78.
Ian Plimer, who's just a geologist gadfly, is 72. (Pity, I thought he was probably a bit older than that.)
Curry is 63 or 65 - accounts seem to differ - but she looks a bit old for her age. Monckton is 66, but could pass for older too. I can't see how old John Christy is, but he was married for 39 years, which would indicate he is likely at least 60. White haired Roy Spencer is 62.
I'm not sure it's possible to find a climate scientist who counts as a skeptic/lukewarmer who is under 60.
So, I guess a few of them will be with us for a while yet, but time will eventually remove climate change denialism.
