Nature "Discovers" Another Climate Audit Finding

In an article in Nature today by Thompson, Kennedy, Wallace and Phil Jones claim: Here we call attention to a previously overlooked discontinuity in the record at 1945, Well, folks, the discontinuity may have been overlooked by Hadley Center, CRU, NOAA and NASA and by the stadiums of IPCC peer reviewers, but it wasn’t overlooked […]

Rasmus, the Chevalier and Bucket Adjustments

We’ve heard a lot recently from RC about whether solar can account for temperature variations in the 20th century. While my primary interest in these ruminations is the possibility of pinning down a set of standards by which they agree that a study is “bad” – since it’s hard for me to determine any sins […]

The New “IPCC Test” for Long-Term Persistence

In browsing AR4 chapter 3, I encountered something that seems very strange in Table 3.2 which reports trends and trend significance for a variety of prominent temperature series (HAdCRU, HadSST, CRUTem). The caption states: The Durbin Watson D-statistic (not shown) for the residuals, after allowing for first-order serial correlation, never indicates significant positive serial correlation. […]

Recyclable AbathyThermograph Instruments

Lyman et al have had to correct their paper on ocean cooling, as the effect that they observed has proved to derive in part from a bias from “Xpendable Bathy Thermograph (XBT) instruments”. They report The rapid decrease in globally integrated upper (0—750 m) ocean heat content anomalies (OHCA) between 2003 and 2005 reported by […]

The Team and Pearl Harbor

One of the Team’s more adventurous assumptions in creating temperature histories is that there was an abrupt and universal change in SST measurement methods away from buckets to engine inlets in 1941, coinciding with the U.S. entry into World War II. As a result, Folland et al introduced an abrupt adjustment of 0.3 deg C […]

Buckets and Engines

Here is a remarkable graphic from a new publication, Kent et al 2007, showing the distribution of SST measurements between buckets and engine inlets from 1970 on. I think that this evidence has great significance for the Folland and Parker SST adjustment, which is one of the most fundamental Team adjustments. I’ll discuss this more […]

ICOADS SST Data

There is an enormous online archive of SST measurements, which would be well worth someone looking at, to get a feel for what the raw data looks like.

Hansen Calls IPCC Adjustments "Ad Hoc" and of "Dubious Validity"

A while ago, I made a couple of posts on CRU adjustments to 19th century SST estimates based on their speculations about the use of canvas and wooden buckets. (While I’ve posted some questions about land temperature records, there is a far more pressing need to wade through SST procedures. My earlier posts were here […]

Southern Ocean Temperature Trends

I pointed out a few posts ago that Antarctic temperatures had been declining during the period of satellite measurement.’ IPCC 4AR Second Draft says that “recent warming is strongly evident at all latitudes in SSTs over each of the oceans“.’ “Strongly” seems to be a new favorite word – think of all the times that […]

IPCC and Solar Correlations

Here’s a post which I wrote last June but didn’t post up at the time because the NAS Panel report came out and I had other pressing matters to comment on. My post as then drafted started: Last week, through Chefen, Jean S and myself, here here here and here , we showed that MBH98 […]
