Me: …except if you’re concerned about Arctic Sea Ice. Its been significantly below trend for this time of year. One small piece of evidence for the existence of climate change.
CCD: Come on old boy! Its not that far off the 1979-2000 average. I don’t think its really worthy of worry! In fact, a lot of sea ice extent is determined by the wind! Its being blown about. Damn unfortunate for those polar bears, but nothing worthy of worry.
Me: I see. Just the wind? A one off? I’m sorry, but could I direct you towards this graph? But, I’m really glad to see you want to engage in good faith.
CCD: [Ponders a discussion in good faith…] Its been faked! They’ve hid the decline! No… they’ve faked the decline! Its the tree rings donchaknow!
repeat ad nauseam
