Climateaudit.org mentioned as science resource!

Well, almost… (if you follow me). There’s a new piece of open source software for Web browsers called "Site Bar" which you can find at this link If you install it (and it’s as simple as clicking a link) you’ll get a sidebar full of links to interesting sites. If you select "Sience" then you’ll […]

Post-1980 Proxies #1: Twisted Tree Heartrot Hill

I get a lot of questions about post-1980 proxies and I find it a very interesting question. One would expect that 1998 – the "warmest" year of the millennium – and the 1990s – the "warmest decade" of the millennium would leave a loud signal in a valid proxy. I’m going to start discussing some […]

Some Thoughts on Disclosure and Due Diligence in Climate Science

This post seems to have caught a chord and has quickly become the most read posting on the site. It was was cited approvingly by Roger Pielke at his blog [now here] and re-printed with slight edits by National Post on Feb. 15, 2005.

Global TV (Canada) – Feb. 13, 2005

Ross McKitrick was on Global TV yesterday and gave an excellent presentation, especially in comparison to the Canadian Environment Minister, Stephane Dion.

Wall Street Journal – Feb. 14, 2005

There’s going to be an article about the work of M&M in tomorrow’s Wall Street Journal. (Update: Here’s a url Here’s what’s on the online coverpage: Climate Graphic Faces Attack Since it was published four years ago, the "hockey stick" temperature graph has been used by hundreds of environmentalists, scientists and policy makers to make […]

Errors Matter #3: Preisendorfer’s Rule N

In the last two days, I’ve argued that it’s insufficient for Mann et al. to merely “get” a hockey stick shape some other way, but that they have to show that any such salvage reconstruction meets the representations and warranties of MBH98 as to reasonably even spatial sampling, robustness, statistical skill and proxy validity. I’ve […]

The Dutch experience of sea-level rise

Following on from the prompting of Hans Errin, I took a look at his links on climate change in his country. The Dutch National Institute for Coastal and Marine Management (KNMI) produced the following picture (taken from this document). As you can see, sea levels were higher during the Medieval Warm Period (1000 years ago) […]

"A Dynamic Group of Coffee Drinkers"

While I was working up some other notes, I checked Mann’s reference to a presentation by Jolliffe, supposedly justifying de-centered uncentered principal components analysis. (It doesn’t, but that’s for another day.) Anyway, the hyperlink has disappeared. Chasing up the directory chain, the Jolliffe presentation had been previously stored by the Climate Systems Analysis Group of […]

"Better for Our Purposes"

Can anyone explain to me the meaning of the following email from Hughes to Mann, dated July 29, 1997, archived at Mann’s FTP site at ftp://holocene.evsc.virginia.edu/pub/MBH98/TREE/VAGANOV/ORIG/malcolm_29-JUL-97. As follow-up, the site arge030 was listed in the original SI as being used in MBH98, but was not actually used in MBH98 calculations evidenced at Mann’s FTP site. […]
