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 […]

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 […]

Warwick Hughes on SST Trends

Warwick Hughes has an interesting post here on SST trends.

SST Adjustment #2

A little while ago, I mentioned here the curious and very large adjustment to 19th century sea surface temperatures based on changing hypotheses about the relative use of wood and canvas buckets. It’s always worth checking whether there’s a hidden agenda for seemingly innocent adjustments. Sometimes my instincts are pretty good. Here’s Figure 3.20 from […]

Changing Adjustments to 19th Century SST

While there has been a great deal of discussion in other locations about possible urban heat island effect, there has been relatively little discussion about SST (sea surface temperature) adjustments and NMAT (night marine air temperature) adjustments. This is too bad. I’m not going to get into this, but there are some handy sources which […]
