Jacoby is a key player on the Hockey Team. Jacoby and d’Arrigo have received nearly $8 million from the National Science Foundation (collated from public NSF records)- see here ; in addition, they have received an undisclosed amount of funding from other public agencies (collated from publication references). As far as I’m concerned, US federal […]
As noted before, IPCC 1995 (SAR) arrived at the following important new conclusion based only on Wigley and Kelly 1990, as stated in the Chapter 3 Executive Summary: Based on the incomplete observations and paleoclimatic evidence available, it seems unlikely that global mean temperatures have increased by 1 deg C or more in a century […]
I was browsing through some Jacoby articles for a different purpose and was reminded of the very interesting references to a relationship between high-latitude tree ring growth and southern exposure to the sun in two of his 1980s articles, which do not get mentioned any more once the GW campaign is on.
A new study on Alpine glaciers has shown that the recent melting since the lowest point of the "Little Ice Age" in the 17th Century is not extraordinary in the context of climate change since the end of the last Ice Age: The Alpine glaciers are shrinking, that much we know. But new research suggests […]
Bunn et al. [2005] have an interesting discussion of 20th century tree growth (especially foxtail pines) in the Sierra Nevada and White Mountains, in the current Holocene, which, needless to say, was interesting to me. The extraordinary and uncritical embedding of MBH98-99 in paleoclimate mentality recurs here in a curious way. Roger Pielke wondered whether […]
Bring the discussion of a couple of days ago further forward, here is a very interesting graphic from Ravelo and Ward [2004] showing the transition from Pliocene to the Pleistocene (read R to L), which gives a somewhat different perspective on the Pleistocene than just looking at the Vostok core back to 800K (although that’s […]
I gave a speech last week at my tennis/squash club on climate change (which presents speeches from time to time). I included some geological concepts that I don’t usually have an opportunity to talk about. The class of scientist who tend to be most unimpressed with IPCC-type climate science are geologists – which is where […]
I might as well illustrate real-time frustrations in dealing with the Hockey Team. I’ve written back on Jacoby’s stonewalling to Climatic Change (who have been trying and who at least got a refusal from Jacoby) as follows.
I’ve been trying for over a year to get a location for the Gaspé cedars. Jacoby, as a Hockey Team member, refuses to provide such mundane information. At one point, Ed Cook, another Hockey Team member, promised to provide the information, but failed to deliver. Now Jacoby has told Climatic Change that the cedar location […]
In most "long" presentations of climate change in the IPCC framework, we see Vostok ice core going back to about 800 Kyr, covering most of the Pleistocene. What easily gets lost sight of in this format is just how unusual the Pleistocene itself is. It is one of only a few glaciations in the entire […]

Alpine Glaciers "disappeared 7000 years ago"
