James Lane here noticed a couple of other useful references on Quelccaya and related the anecdotal information to this information. He observed: It took me ages to put this post together, juggling between different sites. I don’t think one can conclude anything from the information, as presented, except that the moss has grown at higher […]
One of the Kevins has drawn Appendix A “Statistical Issues Regarding Trends” in the recent USCCSP report "Temperature Trends in the Lower Atmosphere" to my attention. The appendix is coauthored by the omnipresent Wigley.
The nearly useful "Recent Comments List" plug-in has been upgraded. It now works correctly. If the any string of letters (such as a URL) is more than ten fifteen characters long then it replaces the long character string with "…" which should stop the moaning from the IE6 users. fFreddy: I owe you a pint.
Thompson et al (PNAS 2006) stated that the discovery of a plant deposit with radiocarbon age of around 4000 BP (calibrated to 5138 BP) near the receding margin of the Quelccaya glacier provided “strong evidence” that the “current retreat of Quelccaya is unprecedented for the last 5 millennia”. The plant deposit is Distichia muscoides, which […]
Last week, Mann et al published a letter in the Nature Correspondence section saying that it was "hard to imagine how much more explicit" they could have been about the uncertainties and blaming "poor communication by others" for the "subsequent confusion", disucssed here. The Mann et al letter is absurd and Ross and I decided […]
Just when I’d despaired of ever seeing anything as mundane as a site map of the Quelccaya glacier on a scale that did not also show all of South America, I stumbled (due to the wonders of google) on an interesting article by Mark et al (2002), a geologist from Ohio State – the same […]
In a few days, we will reach the anniversary of the formation of Hurricane Katrina in the middle Atlantic (Aug 18, 2005). By this time last year, we’d had 4 hurricanes, including two category 4/5 hurricanes, with Katrina about to hit. The final 2005 tally was 28 named storms, 15 hurricanes, 7 "major" (Category 3 […]
Can we agree that the discovery of Distachia at Quelccaya dated to about 5000 year ago and located about 400-500 m above its present level is evidence that it was warmer at that time than at present at Quelccaya, Peru? Yeah, yeah, I know the argument that maybe Distachia is 400-500 m out of equilibrium […]
Warwick Hughes has an interesting post here on SST trends.
Just when you thought that there was nothing left to say about MBH98, look at this MBH98 "flavor" that the cat dragged in today. This is a MBH-flavor reconstruction using MBH methodology and MBH proxies, following one of the NAS panel suggestions!! What did I do? Figure 1. A New MBH98 Flavor
