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 […]

We Have 25 Years Invested in This Work…

Some of you may recall the memorable climate science phrase: We have 25 or so years invested in the work. Why should I make the data available to you, when your aim is to try and find something wrong with it. Here’s the story behind this and some updates on it.

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 […]
