You can't kill a zombie
Ben Goldacre writes the regular Bad Science column in the Guardian. Normally he sticks to medical issues, particularly the MMR scare, but he turned his scathing eye to climate change denial this week and gave us a new phrase - "zombie arguments". These are the arguments that keep coming back no matter how many times you blow it to smithereens - global cooling in the 70s, mediaeval warm period, no warming since 1998 and all the usual suspects. You can try using the well rehearsed responses listed at Grist, New Scientist or try the heavy artillery of scientific argument at Real Climate, but you won't kill zombies with mere facts - they keep coming back.
BTW, I had lunch on Saturday with a leading climatologist. He's very relieved that none of his e-mails to Phil Jones at CRU have been through the denialists' distortion mill and says that Phil Jones is a true gent and completely above reproach. The New Scientist debunking of the e-mail allegations is worth a read - there really is nothing in it.
