Jim,

Thanks for a good list of publications. I’ll try to look into them.

What the %*&!@# does that have to do with anything? The computer code behind the GISS data is what matters, along with the sparsity of the monitoring stations, the frequent station moves, removing stations, citing stations on concrete, asphalt, and tarmac, the list is just too long!! The fact is that GISS is useless for climate research. I’m betting the same is true for HADCRU – otherwise they would quit hiding behind this and that excuse and publish it for all the world to see. The sad truth is that because GISS has been so badly managed, we don’t have any reliable land/sea surface temperature data for the last 100 – 200 years.

Here is the UAH documentation. As you can see, UAH have been very public with their methodology – now where is the HADCRU documentation?

Aside from the fact that you say qualitative when you mean quantitative-why don’t you try actually doing such a comparison? I told you what such a comparison, if done properly (or even not done properly) would say-GISS has a warm bias. Your misdirection to the issue of month to month variability is odd, surely it is the trend comparison which really matters-SO TRY DOING ONE SOME TIME! Call us back to tell us to give up when you have done a comparison to find the difference in trends.

Do your homework lassy, or don’t come back to school at all.

The short term comparisons attempted here turned out to be flawed. And the UAH scientists do not support the use of UAH monthly data to attack GISS monthly data. The different temperature records measure different variables, with different assumptions, often with different base periods (for calculating the anomalies). Give it up, and get over it.

The reason why is that we expect the LT change to be greater than the surface change. Of course, even ignoring the caveats, one can see that the expectation of greater warming aloft than at the surface doesn’t hold up, strongly suggesting that something is amiss with either 1. Theory 2. Models 3. Data or some combination (note that if theory is wrong, the models are also wrong).

Hardly suggests to me a “loss” for WUWT and a “win” for sophomoric dopes who declare victory based on the fact that a battle is over, before making body counts…

The monthly UAH data cannot be compared directly with the GISS data…

Why the hell not??

With CO2 rising and the planet’s temperature falling, your falsified CO2=AGW hypothesis is in shambles. Forget skeptics, the planet itself is laughing at your hubris.

Isn’t it true that even the UAH scientists are shying away from directly comparing their monthly anomalies with the other records? I see no real scientific support at all for the WUWT comparisons.

You say Bring it, boys. We brought it, and lets face it, the WUWT regulars lost this argument. Get over it. You don’t have any legs left to stand to on to support the comparisons made here.

Changing the subject to arcane minutiae of how the anomalies are calculated won’t change the major issue here. The monthly UAH data cannot be compared directly with the GISS data, and even the UAH guys say that they don’t question specific GISS monthly data.

“” Jim (12:57:41) :

The Iceberg (12:27:54) : Is the methodology used for HADCRU data processing public?”

Is the methodology of UAH processing public?”

Good question! I’ll ask.

The Iceberg (12:27:54) : Is the methodology used for HADCRU data processing public?”

Is the methodology of UAH processing public?

Why oh Why can’t some people accept that Christy is so far out for his monthly anomaly that it beggars belief.

Currently UAH data is running around 0.5C ahead of July this time last year, I wonder what the monthly anomaly will be come 2 mins past midnight on the 1st of August.

To me it’s obvious that before the 98 El Nino UAH was the last of the datasets to start the sharp upward trend, the same is happening this time, July will pop up to be the 4th or 5th warmest on record for UAH and guess what, WUWT probably won’t run the story……
