An amusing comment today from Roger Pielke Jr. about his experience as ringmaster of an on line debate over the relevance of the hockey stick climate reconstruction, placing himself squarely between warring tribes as he tried (with some success, I thought) to spark a useful discussion. I found it amusing to find myself being attacked …

A new paper by Jian Lu and Thomas Delworth argues tentatively for a link between greenhouse warming and drought in the Sahel.(Lu and Delworth, 2005) This matters, of course, far more than my usual hobbyhorse of drought in the southwestern U.S. Here when our water supplies run low because of drought, we suffer economic dislocation. …
Kevin Vranes pretty much nails it with an insightful analysis at Prometheus about the way the hockey stick debate has become such an odd sideshow: Inaction was the political response to the 2001 SPM* presentation of the hockey stick. The hockey stick both as science and icon could not have been more hyped. But They …
If I may, then, in my next breath criticize my good friend Tim Lambert whom I’ve never met, I think his post this morning on CEI bloviator Ian Murray’s remarkable global climate change conversation rather misses he point. Murray used to be a serial denier of the consensus science on climate change. Now, in a …

A discussion over at RealClimate about media coverage of climate change (an issue dear to my heart) sent me back to read a widely quoted paper last year by Boykoff and Boykoff – Balance as bias: global warming and the US prestige press.
The Barnett paper I quoted below talks about hydrologic changes “already diagnosed in some regions.” A reminder for those of you in the Western U.S. – we’re one of those regions.
A paper in Nature by Tim Barnett at Scripps and Jenny Adam and Dennis Lettenmaier at the University of Washington suggests climate change problems for folks who depend on snowpack for their water supplies: All currently available climate models predict a near-surface warming trend under the influence of rising levels of greenhouse gases in the …
Ross McKitrick and Steve McIntryre have taken Roger Pielke Jr. up on his offer that they spell out their arguments about “why those of us not involved in the hockey stick fight should care about the continuing battles.” Neither offers any argument whatsoever regarding how this might influence my thinking about what policy choices I …
Given my personal feeling that variability is the climate change bugaboo that matters the most, I spent a lot of time thinking and asking about last year’s Science paper by Hans von Storch about variability in the paleo record. Now there’s a new paper in Journal of Climate by Mann, Rutherford, Wahl and Amman that …
Global warming has its winners as well as losers: That’s a hollyhock in the front garden, still blooming away two weeks after the average first fall freeze date in Albuquerque. Overnight lows for November in Albuquerque this month have averaged 42 F, 7 1/2 degrees above average. Daytime highs are 8 degrees above average. Obviously …
