Here’s bender’s plot of the number of hurricanes, showing the difference between plotting on an annual and boxed basis. There are statistical issues in fitting trend lines to spiky data like this, which bender is well aware of and pointed out in the predecessor thread. If Curry is unaware of these issues, what does that […]
We have an op ed in the National Post today about the Wegman Report. In addition, Terence Corcoran has a long article about a recent hatchet job published by the Globe and Mail about Tim Ball from a writer named Charles Montgomery. I had to laugh out loud at the following comments by Corcoran about […]
A while ago, I summarized an interesting article from the Venezuelan Andes. In that case, they concluded that the glaciers did not exist in the MWP. The post is worth re-reading in the context of Quelccaya. The authors used the continuous deposition of sediments in a proglacial lake to yield evidence of the discontinuous movements […]
Before Caspar Ammann started playing for the Team, he was a geologist who wrote the following serviceable discussion of glaciation in the “dry” Andes between 19 and 27S (Quelccaya is at 12S). Under current climatic conditions, no glaciers can exist in the high Andes of the Western Cordillera in the high Andes of the Western […]
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 […]
