Here's a New Scientist editorial pointing out the absurdity of Dr. S Fred Singer and Dennis Avery's recent PR campaign attacking the science of global warming.
It's behind a pay-per-view wall, so I've pulled a few quotes for those who don't have access to the whole article:
We need climate change sceptics. Not because they are right - at least not on the big issue of human culpability in recent warming - but because they ask hard questions that lead to deeper knowledge. What we do not need from them is misrepresentation and cynical trashing of scientists' work.”
