Anthony Watts at UCAR

Anthony’s presentation at Roger Pielke Sr’s seminar at UCAR appears to have been well-received. He’s posted some interested online reports at his blog and been written up here and here. In response to the criticisms about the failure of sites to meet standards, Lawrimore of NOAA said that they already adjusted for these problems: For […]

MBH Proxies in Bo Li et al

We have a new article from the Mannian school, this time involving supposedly “independent” NAS panelist, Doug Nychka, and geologist Caspar Ammann, who is very enthusiastic about calculating covariances using Mannian proxies. The lead author is a statistician, Bo Li. The article purports to use MBH99 proxies and says we do not critically evaluate these […]

Waldo: South America

Waldo, Hansen’s ROW trend, is not in Africa nor in Antarctica. Is Waldo in South America?

Where's Waldo: Antarctica #2

If you’ve not read Where’s Waldo: Antarctica #1, please do so first.

Where's Caspar?

As you know, we are eagerly awaiting the publication of the following article by Wahl and Ammann reported here: Wahl, E and C Ammann (In press). “Robustness of the Mann, Bradley, Hughes reconstruction of northern hemisphere surface temperatures: Examination of criticisms based on the nature and processing of proxy climate evidence.” Climatic Change (accepted). May […]

Where's Waldo: Antarctica #1

Waldo (the ROW warm trend) is not in Africa (or the United States). Is Waldo in Antarctica? (For those of you who haven’t bought toys in 30 years, Where’s Waldo is a game.) Antarctica is about 8.9% of the world’s land surface (about 1.5 times the contiguous 48). There are 116 Antarctica sites in the […]

Unthreaded #19

No discussion of CO2 measurements please.

Waldo in Africa

Gavin Schmidt and James Hansen say that errors in the U.S. “don’t matter” because it is only 2% of the earth’s surface (about 6% of the land surface). This implies that the accuracy of measurements in other parts of the world can be relied on. In the U.S. the 1930s have a similar level to […]

Jesting with Adjusters

Hansen tells us that he won’t “joust with jesters”, as presumably he’s too busy adjusting to have time for jousting. We by contrast have lots of time to jest with adjusters.

Tucson Then and Now

In the discussion of my previous post, a reader posted a link to a fascinating picture of Tucson in 1923 – a picture complete with Stevenson screen in the foreground, if you can imagine, clearly visible on the right. Figure 1. Tucson c. 1923. From left to right: Agriculture Building, Old Main, and the Mines […]
