NASA GISS has released their global temperature anomaly data for June 2009 and it is quite the surprise.
In both the UAH and RSS satellite data sets, global temperature anomaly went down in June. GISS went up, and is now the largest June anomaly since 1998, when we had the super El Nino.
Data source:

Here are the June global temperature anomaly comparisons:
GISS .63C
RSS .075
UAH .001
The divergence between the satellite derived global temperature anomalies of UAH and RSS and the GISS land-ocean anomaly is the largest in recent memory.
But that isn’t the only oddity. Over on Lucia’s blog, the first commenter out of the gate, “Nylo” noticed something odd:

Regarding updates in past temperatures, this is not the most important change. Very noticeable is the fact that now 2007 is the second hottest year, having replaced 1998 in the statistics. This has been achieved by lowering the 1998 J-D average temperature anomaly to 0.56 , and raising the 2007 J-D average temperature anomaly to 0.57. Last month they were viceversa.
It is curious to me that such adjustments in GISS seem to occur in a way that enhances the present trend. Perhaps it is like a fine liqueur, aged to perfection.

I checked Pravda for word of catastrophic warming, or massive heat wave, being reported for Siberia. Nothing. Not a word.
So I look at the map for my own neck of the woods, noting the very cool June we had, and see a big red dot. Huh?
I have been out with the tech who routinely replaces failed sensors with sensors from other problem stations. They have no pool of good replacements as they are alloted only so many for the year. Never enough to keep the system running correctly.
So, it matters not what opinions we have or don’t have as to why this is going on.
It really does matter that the output of Global Mean Temp. has a blown head gasket.
It really does matter that it is so bad that nobody can ignore it.
It’s even sadder that the folks who are supposed to be running this GMT report could care less how shockingly wrong it really is.
No one should be surprised, then, or shocked, that many are searching for the reasons.
I guess I should post this question here. When GISS says they remove outliers, “Reynolds v2 using elimination of outliers and homogeneity adjustment”, does this mean that they drop temperatures considered to be outliers? I am curious as to what that means. If it means temperatures, then they are set up to a warm bias. July couldn’t have many days (that we would live to write about) 3 stdevs above the norm, but it could below the norm.
Anyone know what outliers are eliminated?
Re: F Kassen (23:32:12) :
No FK, it is you that is completely wrong. Warmer is better! The science is certainly settled in regards to warmer, wetter, higher CO2, conditions will increase biomass (our food supply, mainly plants). Many greenhouses employ these very enhancements to increase yields. The ideal climate is not the ideal climate for Man, per se. The ideal climate is the ideal for our food source. Us humans must adapt to the ideal climate for our food source. It is the ONLY way to continuing to feed increasing billions. Any serious cooling immediately decreases yields and the woe begins.
You exhibit the very intolerance that identifies rabid AGWers. Are you in disguise?? Mike D is a better skeptic than you.
