Al Gore’s hockey stick is from Lonnie Thompson’s ice cores. [Update: subsequent to this, we discovered that Al Gore’s hockey stick is not “DR Thompson’s thermometer” but Mann’s hockey stick wearing a wig.] On previous occasions, we’ve talked about the Guliya ice core -Thompson’s failure to archive data; the use of three different and inconsistent […]
Here’s an interesting SST proxy from the Gulf of Mexico that I meant to report on last October, but is actually more timely now given our recent discussion of hurricanes. When I corresponded with Lloyd Keigwin around the time of the Juckes submission, he mentioned a “beautiful” unpublished high resolution core from Poore in the […]
It’s a dangerous practice to let your eye get teased into visual comparisons, but I was struck by a comparison between the G Bulloides series from the Arabian Sea (which is an upwelling proxy) and Stott’s Warm Pool SST proxies.
The Team (at both realclimate and NOAA) have stated in the strongest possible terms that the Holocene Optimum was restricted to summer in the NH extratropics. Reviewing their positions, realclimate here The [Holocene Optimum] is a somewhat outdated term used to refer to a sub-interval of the Holocene period from 5000-7000 years ago during which […]
Despite the protestations of the Team, it seems to be a consensus of other paleoclimatologists that the Holocene Optimum was warmer at high southern latitudes. For now, I’ll take this as read, although it’s well worth canvassing the literature. Some citations are at ukweatherworld. The next line of Team attack on the Holocene Optimum is […]
After several years of trying, Briffa and Osborn have finally listed the sites used in Briffa et al 2001 and related publications. Briffa had reported results on large networks of over 300 sites collected by Schweingruber. Schweingruber had archived over 400 sites at WDCP. However, it was impossible to tell exactly which sites had been […]
You may recall Hansen’s strange splice of modern instrumental records with a Mg/Ca SST proxy ending in 4320 BP based on a partially dissolved core.’ A couple of months ago, I mentioned a new paper by Newton et al (including L Stott) with a high Warm Pool MWP and briefly discussed Netwon’s presentation at AGU […]
Here’s an interesting graphic from lecture notes of Jed Schneider and Kathryn Clapp here showing the flow of ice through a mountain glacier. If this is representative of flow in mountain glaciers, one wonders at what exactly is being recorded in a vertical drill hole away from the summit (such as Guliya Core 2). I’ll […]
Three cores were drilled at Dasuopu. We don’t hear much about Core #1. It was drilled in a flow zone and, despite being 160 m deep, is only back to 1922 in the most recent discussion. I’m intrigued with this for a variety of reasons, including the fact that Guliya Core #3, the one that […]
It is impossible to convey the overwhelming number of papers and presentations here. Through the week, my notes have invariably deteriorated. By the time you get home, they are unintelligible. I’ m going to diarize them a little — so I don’t forget totally and to share a bit of the experience. (And since CA […]
