Been undertaking one of my regular trawls through the climate change denial blogs.
Depressing as always, not so much because of Climate Change itself. If it's true, that's depressing, if the denialists are right, that's obviously a good thing.
No, what's depressing is the degree to which politics and special interest and pride and anger, resentment and malice seem to be involved in the debate.
It looks like it's on both sides. The denialists are big on highlighting stupid and pompous and venal prevaricating statements by climate change scientists. It's harder to guage whether that's a representative sampling or if they've goaded those scientists into intemperate outbursts which are then gleefully seized on as evidence of those same scientists' worthlessness.
Whichever is the case, the tools of the internet are being turned to the destruction of a knowledge and the sowing of confusion rather than it's creation, refinement and promulgation.
What's needed is something better than newspapers and television documentaries and blogs and graphs as a way of structuring this debate.
Update : Maybe we need things like this. Or TruthMapping which seems very close to a working Typed Threaded Discussion.
