Which don’t have the Sept data yet and the year up to August is given as

2009 0.384 0.364 0.371 0.415 0.407 0.499 0.498 0.532

Where the heck are your figures from?

Something seems funny with those numbers at the end. What are the chances of this series at the end happening as a repeating identical pattern?

Good, since they’re for September, the ninth number after the date. Patrik must have had problems pasting, or he’s having a little joke at HadCrut’s expense.

Your Nigel Lawson quote: “…it always takes longer to add them up when the numbers are giving you bad news.”

Which would be the bad news, cooling or warming?

And thanks, E.M. Very impressive and useful work.
====================================

It’s 136. From:

Would You Believe a Little Over 2 Thermometers Per State?
And no, that is not a “Maxwell Smart” imitation.

My “by years” tool told me there were 136 active thermometer records in the U.S.A. in 2008. For the whole thing. Including Alaska and Hawaii. But in fairness, Hawaii got three thermometers, all at airports.

And this brings up a point about the fragile nature of the gauge network. What if we the people, the keepers of the sensors, just decided to get off this silly train?

While I loved your imagery, the reality looks to be far more dull, and far more damaging.

GIStemp gets it’s “raw” input data from 2 sources. One is the USHCN – the US thermometers that Anthony et. al. are so focused on. These are all still in use and still being used to forecast weather. The data flows, via NOAA, into a publicly available data set. Unfortunately, NOAA changed the data format to something called Version 2 or USHCN.v2 and when they did that, GIStemp declined to do any maintenance programming to download the new USHCN.v2 file with all the new temperature readings in it. So US data ‘cuts off’ from USHCN at that point in time.

The US data also flowed in via the GHCN, the Global thermometer network, but after a conversion from F to C and a few other changes in how it is fudged. Fine you say?

Well, not quite…

It seems that at about the same time, GHCN decided to drop all but 136 US thermometers (leaving California with NONE in the cold snowy parts: we have 4, one in SFO and 3 near the beach in So.Cal: LA, San Diego, Santa Maria). Kind of hard to get anything OTHER than record heat when you do that…

So every single temperature anomaly reported for the USA since 2007 is flat out bogus.

Every
Single
One.

Why? Who knows. You might suspect a similar failure to follow the USHCN data format change; but then you would have to explain the 136 that do get in to GHCN somehow…

There was a World Meteorology agency of some sort calling for a Global Climate system about 1990 and it’s possible that everyone just hopped on the bandwagon of picking a couple of hundred “good thermometers” for each continent and didn’t bother to think through that this would completely break GIStemp. (And, I suspect, Hadley. They must get their input from somewhere, and if not GHCN, then where? Hmmm?)

I’ve been exploring the degree of damage to the GHCN data set and found great deletions scattered all over the world. Many focus on a date near 1990. The end result of it is little thing, like:

Japan has no thermometers above 300 meters. Nope, not a one. It’s as flat as Kansas as far as GHCN is concerned.

93% of the thermometers in the USA are ignored. If you want their data, you have to “go fish” in the USHCN.v2 pool on your own.

Australian thermometers are migrating to the northern beaches.

And in New Zealand, and “Inconvenient Island” (Campbell Island) located down near the polar zone was deleted, giving the Kiwi data set a nice lift and a good shot of temperature tonic. If you take the record out of the past (which GHCN does not do…) so that you have a stable composite instrument to measure with, New Zealand is not warming. Such power in one little Island…

and there is more. But there is also some good news.

When you look at the bits that have not been molested, like Argentina, you find that it isn’t warming. All the parts of North and South America that have not had significant thermometer deletions show stable temperatures.

The Pacific Ocean (minus Australia and New Zealand, that have been molested) shows no warming at all to speak of. Nice stable temps with a bit of a cyclical roll that I think is the PDO flip flop flipping.

I’ve done an analysis of every continent, most major countries by land area, and a couple of minor places and links to them are here:

http://chiefio.wordpress.com/2009/11/03/ghcn-the-global-analysis/

which also has directions on how to download the data and includes, near the bottom, the source code for the software to do a lot of this yourself.

So what do I think happened with the Hadley data (this time…)? I think it was likely one of two things:

1) It showed the world really IS getting cold and they just could not believe it. (I think this is unlikely, given the “cooked” state of GHCN).

2) It showed things like the bogus 115 year record heat in California and maybe, just maybe, they realized that this was “A Whopper Too Far” to cross…

I’d bet my money on #2. I would speculate they are using GHCN data, and that they have just started to have the lag from 2007 that most averaging type adjustments will put into a series wear off. This would result in unbelievable warming spikes (such as in California) and they are probably trying to “figure out what is wrong”. Well, it only took me about a half a year, so give them a while… But make sure they keep the dog on a tether and his bowl full of kibble. We don’t need any more Hadley being “The Dogs Lunch”, now do we …

And for those who have found what I’m doing worthy of mention to others: Thanks! It makes it worth while…

Now what I’m left to ponder is this:

With GIStemp (marginal to begin with) completely broken now due to the USHCN.v2 breakage and GHCN ‘thermometer mass dying”;

With Hadley being “The Dogs Lunch”;

With satellites being too short a history to use and calibrated against what again? Oh, perhaps the land series from Nasa and … oh deary me can i get back later….

Exactly WHAT temperature series is there to use to make any statements about the climate or current trends of temperatures?

I think I’ll look out the window and ask the TV Weather Man …

i think you may be spot on with your last line.

They have already pulled it. Luckily i took a screengrab last night.
