GWPF is wrong, warming has not stopped.

The Daily Mail says that BEST results show that global warming has stopped, citing this graph from the GWPF. And there's an interview with Judith Curry talking about someone "hiding the decline".

Tamino has quite correctly taken this apart. This is his version of the GWPF graph:



As he points out, the claim of no warming is dependent on the dip in April/May 2010. Without it, there is warming, pretty much as expected.

So I checked the BEST data.txt to see why these month data had such large error bars, and were so out of line. It turns out that all the data they have for those months is from 47 Antarctic stations. By contrast, in March 2010 they have 14488 stations.

How this could have happened, I don't know. Anyway, a list of those 47 stations below the jump.

A Javascript index for Moyhu

A Javascript index for Moyhu

I have always tried to maintain an index for Moyhu. It's one of the pages you'll see listed at top right. But there are now 144 posts, and the system needs upgrading. So I made this another exercise in my program to learn Javascript.

The old index, which I'll keep for a few days until this one settles, had posts listed in topic order and then time order. That pretty much kept it to one topic per post. In the new scheme, you'll see below a table of labelled buttons. Click on any one, and related post links will appear in the space below. They should be in time order, newest first. The complete time order listing is below that.

BEST has same data as GHCN pre-1850

BEST extended its temperature series back a lot further than its predecessors, to about 1800. Many have assumed that this was because they have more early data, but this is not true. Their data set in this period is pretty much identical with GHCN.

You can see this from the KMZ file or the interactive Javascript plot. But I thought I should check it out in detail, so I have below a table of the actual stations, in one case from GHCNV2 (V3 is the same) and in the other BEST, taken from their data.txt file.

There are very few discrepancies. Out of about 275 pre-1850 stations, I count only 6 which BEST has and GHCN doesn't. There seem to be 9 than GHCN has that BEST doesn't, and 8 that BEST has included apparently twice. Details below the jump.





Here is a complete table of stations with pre-1850 data.. The color scheme is:

Black	BEST
Red	GHCN
Purple	BEST unique
Blue	GHCN unique
Green	BEST duplicate

The first table is just of the exceptions. I have colored STYKKISHOLMU but not counted it, because it is in both, though BEST seems to have about 20 more years data. Generally I did not color if there is a discrepancy of less than three years in start date. I have shortened names to 12 characters.

World coverage by decade of BEST, GHCN, GSOD and CRUTEM3

Update: I see that the plot does not show in Internet Explorer - I'm trying to find out why. It works in Firefox, Chrome and Safari.

In the previous post, I talked about a KMZ file which would display the stations of the four temperature databases, BEST, GHCN, GSOD and CRUTEM3. They were set in folders so that different starrting dates could be displayed.

This post provides a JavaScript interactive display with the same general intent. There are a total of 52 images, each showing a single database in a single decade (approx). It shows the stations that returned any data in that decade.

Here you see just a single image. There are two legends, one with decade and one with database. You can click on the legend to bring up any combination. There is a control with a square and four triangles. The triangles just navigate up and down the menus in the way they point. The square enables you to toggle rapidly between the last two images shown. The intent is that you can set up pairings and compare.



The images are quite high resolution (1600x960 pixels) so you can use the Ctrl+ and Ctrl- controls to enlarge and see more detail. When you click on an image for the first time, there is a short pause while it downloads.



As you'll see, the daily data, GSOD, has good coverage at present, but doesn't go back far. GHCN goes a long way back, and the BEST coverage seems to use much the same data, with just a few more ststions. But try it out - there is a lot you can test.
