these guys just lie
Look, David Hughes and Chris Nelder are just incapable of telling the truth about shale gas. Follow Nelder's link at the top of the post and look at the absurd graph he posted previously. That was essentially the controversy - the "natural gas plateaued in 2009" nonsense he was pushing, and his previous graph captures in nicely.
Now he pretends that his previous article was completely different, and was based on a "natural gas is peaking in late 2011" prediction. But that wasn't what he was saying at all - he was saying it had peaked a while ago and everyone else was reporting the wrong numbers.
Hughes is, if anything, more delusional then Nelder.
However, people are getting hip to these clowns. A year ago Nelders gas-debunking was making some inroads into the mainstream media - now he is relegated back to the margins.
