OK, here’s something I don’t get: a new paper in GRL by Russell Vose at the National Climatic Data Center suggesting the decrease in the diurnal temperature range slowed dramatically from 1979-2004. Maybe some of you climate types can ‘splain this?
(Backstory for non-climate wonks: The “diurnal temperature range” is the difference between the daytime high and nighttime low. My understanding, based on Karoly et al. in 2003 in Science, was that greenhouse warming would be expected to reduce the DTR by disproportionately increasing the overnight low temperatures. That’s exactly what I see happening in my own little corner of the world, with overnight lows warming a lot more than daytime highs. In other words, DTR is part of my day-to-day experience of global warming. It means my morning bike rides are a bit more comfy.)
