New Details on the Ship of Fools

The precise chronology of the Ship of Fools on December 23 has been a topic of interest on skeptic blogs, including my recent post demonstrating the falsity of Turney’s excuses. However, up to today, this chronology had received zero media coverage, despite several reporters from major media on the Ship of Fools. Today, there are […]

Ship of Fools

Like many others, I’ve been intrigued by the misadventures of the Ship of Fools. Dozens of tourist vessels visit the Antarctic without becoming trapped by ice. So it’s entirely valid to inquire into why the one tourist vessel led by a “climate scientist” became trapped by ice. The leader of the expedition, Chris Turney (also […]

Ice Storms and Climate Change

Thousands of homes in Toronto, including ours, are without power due to an ice storm. More precisely, freezing rain builds up as ice on tree branches, which then break, taking down power lines with them. When I was out this morning, I heard and saw a couple of large branches fall. They are warning that […]

A New Alaskan d18O Series

PAGES2K Arctic introduced a lake sediment d18O series from Kepler Lake, Alaska that hadn’t been used in previous studies. Although O18 data is a workhorse of paleoclimate, O18 data from Alaska (or, for that matter, anywhere in the Arctic hemisphere between 90E and 90W – going east) is very scarce. Thus, the appearance of a […]

Varved Inconsistency

Since AR4, there have been a series of new multiproxy studies, several of which were cited in AR5 (Mann et al 2008; Ljungqvist et al 2010; Christiansen and Ljungqvist 2012; Shi et al 2013). A distinctive feature of these and other recent multiproxy studies is the incorporation of varve thickness and near-equivalent mass accumulation rate […]

Does the observational evidence in AR5 support its/the CMIP5 models’ TCR ranges?

A guest post by Nic Lewis Steve McIntyre pointed out some time ago, here, that almost all the global climate models around which much of the IPCC’s AR5 WGI report was centred had been warming faster than the real climate system over the last 35-odd years, in terms of the key metric of global mean […]

The “Canonical” Varve Thickness Series

Shi et al 2013 use the following five varve thickness series, all of which have become widely used in multiproxy series since their introduction in Kaufman et al 2009: Big Round Lake and Donard Lake, Baffin Island; Lower Murray Lake, Ellesmere Island; and Blue Lake and Iceberg Lake, Alaska. Some of these proxies have been […]

More on Hvitarvatn Varves

In a previous post on PAGES2K Arctic, I pointed out that they had used the Hvitarvatn, Iceland series (PAGES2K version shown below), upside-down to the interpretation of the original authors (Miller et al), who had interpreted thick varves as evidence of the Little Ice Age. A few days ago, Miller and coauthors archived a variety […]

Bristlecone Addiction in Shi et al 2013

Recently, Robert Way drew attention to Shi et al 2013 (online here), a multiproxy study cited in AR5, but not yet discussed at CA. The paper by Shi et al (2013) is fairly convincing as to at least the last 1,000 years in the Northern Hemisphere. I am actually surprised that paper has not been […]

Data Coverage in Cowtan and Way

As I was reading section 3 (Global temperature reconstruction) of the Cowtan and Way paper, I came across this text: The HadCRUT4 map series was therefore renormalised to match the UAH baseline period of 1981-2010. For each map cell and each month of the year, the mean value of that cell during the baseline period […]
