Everyone has their own spin on things, but its still not nice to be misrepresented, especially in support of someone elses agenda. RP Sr would like the 2003 heat wave to be unrelated to GW. It may well be; it was such an exceptional event that it would remain outside the stats even if you factor in GW. Rather than looking at sfc T, which seems to be the natural thing to do, Chase et al (inc RP) looked at 1000-500 hPa depth, which is a broad measure of temperature in this layer. They find that by this measure that 2003 in Europe wasn’t exceptional: similar anomalies have occurred elsewhere. I agree. But to say Recently, William Connelly [sic] tested our claim and confirmed our conclusions is wrong; I replicated their results but then found that if you looked at surface temperature you got a totally different picture: that 2003 is indeed exceptional. Once you’ve agreed that 2003 was indeed exceptional you can then look at why; sfc drying seems likely; which of course raises the obvious question as to why the sfc was dry.
