Gavin Schmidt asks at RealClimate: “How should one make graphics that appropriately compare models and observations?” and goes on to reconstruct John Christy’s updated comparison between climate models and satellite temperature measurements. The reconstruction was cited here by Simon in response to Gary Kerkin’s reference to Christy’s graph ( – h/t Richard Cumming, Gary Kerkin and Simon for references). Continue Reading →
Gavin Schmidt and Reference Period “Trickery”
— by Steve McIntyre, Climate Audit – Apr 19, 2016
This is an adopted article.
In the past few weeks, I’ve been re-examining the long-standing dispute over the discrepancy between models and observations in the tropical troposphere. My interest was prompted in part by Gavin Schmidt’s recent attack on a graphic used by John Christy in numerous presentations (see recent discussion here by Judy Curry). Schmidt made the sort of offensive allegations that he makes far too often: Continue Reading →
It has taken me a while to follow up on this letter I sent to Gavin Schmidt on 5 March, 2010. It will come as no surprise to anyone that he hasn’t deigned to answer my email. However, as it expresses succinctly some of the main defences against the “denier” appellation I’ll put it up for comment.

I’m disappointed to hear you quoted (below) apparently referring to climate “sceptics” as “nutters”.
For it is not mental instability that requires me to want evidence of AGW. It is not insanity to want someone to describe in simple words, without taking too long, without referring me to the hundreds of unfriendly pages of the AR4, the evidence for AGW.
Not, note, evidence for the greenhouse effect, which is indisputable. Continue Reading →
