The RSS Microwave Sounder Unit (MSU) global temperature anomaly data has been published this morning by RSS (Remote Sensing Systems of Santa Rosa, CA).
For March 2008 it has moved a little higher, with a value of .079°C for a change (∆T) of 0.081°C globally from February.
2008 1 -0.070
2008 2 -0.002
2008 3 0.079

The interesting news is the divergence between northern and southern hemispheres, and the plunge seen in the continental USA. I’ll have more on that coming up.
Curiously, at almost the same time the BBC has published an article today headlining: Global temperatures ‘to decrease’
On a related note:
Lucia over at The Blackboard just posted a very well done analysis that takes ENSO into account in falsifying the IPCC AR4 projection of +2.0C/century. Here is her graph showing IPCC AR4 projections compared with observations and best fit trend:

I like a nice round number – 100 comments!
Thank you anna v. The hockey stick, this attempt to revise history, and the process taken to produce and have it published is what told me they had nothing, and thus had to resort to making things up.
Russ, Anthony etc.
Having read Hansen’s latest comments, we really need to think about opening up an online Charlatan Hall of Fame, with Gore and Hansen being the main exhibits.
REPLY: Science is self correcting, I’m sure that they’ll be corrected soon.
Reading the link I already gave above http://www.weatherquestions.com/Roy-Spencer-on-global-warming.htm
started me on the following thoughts and link between Spencer’s observation of “cause versus effect”
“This cause-versus-effect role of the Earth’s natural greenhouse effect is an important distinction. I mentioned above the common explanation that the Earth’s “energy balance results in a roughly constant globally-averaged temperature”. But I believe that this has cause and effect turned around: It is more accurate to say that “Heating by the sun causes weather, which in turn generates a greenhouse effect that is in proportion to the available sunlight”. Unless we understand the processes that limit the Earth’s natural greenhouse effect to its present value, we can’t hope to understand how mankind’s small, 1% enhancement of the greenhouse effect will change global climate.”
and the observation by Gerhard Gerlich and Ralf D. Tscheuschner,
http://arxiv.org/pdf/0707.1161, that the greenhouse effect as pushed by IPCC models is not compatible with the second law of thermodynamics.
I do not think that anybody is disputing that it is the atmosphere that is keeping temperatures in livable numbers on earth, and that humidity and other “green house ” gases play a large role in this. But I do not think there exists a physicist that will go against the second law of thermodynamics.
So there is a paradox.
When there are paradoxes it means that wrong use is being made of available information. In language, it means that two levels that should be held separate, are being confused. A statement from a meta language has been incorporated in the language. It is how the old pardox is resolved: A Cretan said all Cretans are liars. So he was lying, therefor all Cretans are not liars. But if he was telling the truth, then all ….” by setting the Cretan making the observation at a metalevel of the Cretans being observed.
Further I have been thinking of heat pumps with respect to modeling the climate. The way Spencer is describing it, it is like a normal air conditioning heat pump that keeps a steady temperature in a room by doing work, either cooling or heating. In the standard green house model there is no work foreseen. All energy is in watts per meter and is supposed to be balanced like a checkbook. Nevertheless there is enormous energy from the incoming of the sun,( 235 watts/m2) that is stored as kinetic energy in oceans and air, and phase transition energy as in precipitation and evaporation. So it is very simplistic to say 235 in 235 out. These stored energies must be what are providing the “work” to keep consistent with the second thermodynamic theorem, and keep the earth much cooler than it would be if it saturated in humidity. And these are not in the IPCC models in a dynamical way.
anna v,
I’ve looked at the G&T paper several times and find it a bit bizarre. To paraphrase an old movie, I don’t think the 2nd law means what they think it means. For another take on what they did, have a look at http://arxiv.org/abs/0802.4324 – “Proof of the Atmospheric Greenhouse Effect” by Arthur P. Smith.
Ian (14:42:44) :
Yes, it is full of german professor english and perambulating, but the basic observation about the second law on “green house” is simple: Two reservoirs, surface, R1 with temperature T1 and Top Troposphere R2 with T2, T1>T2 unequivocally. To transfer heat from R2 to R1 work must be done, the same as cooling with a refrigerator , or a room on a hot day. Conductivity, reflectivity, insulation,radiation rate etc enter in determining how much work is needed to keep a specific temperature T1 in R1, not on whether work is needed.
I have looked at the Smith paper. He does not treat the second law of thermodynamics, nor in his presentation is the enormous amount of sun energy stored as kinetic energy treated ( he says he does not want to enter the full scale general circulation models) . Maybe if I look at it more carefully I will find where the paradox enters . I suspect it is in treating radiation partially classically and partially expecting quantum mechanical behavior but I have not located the spot. ( energy levels and absorption reemission are quantum mechanical).
The second law paradox in this atmospheric greenhouse model remains.
So it must be that it is mixing up semantics and uses analogies from incompatible frameworks.
Take the particle/wave paradox. It is a paradox when it (our brain) mixes two physics representations, the classical statistical mechanics and motion, and quantum mechanics which by its invention contains as a meta level the untangling of the paradox .
I’ve not read all comments, but have not noticed any about the plausibility of treating the earth as a closed system (with zero sum energy balance). It seems to me that the earth’s self-contained radio thermal source precludes such treatment. From the deepest drilling depths to the uppermost atmosphere there is a temperature difference of about 113 degrees C over a distance of about 13 kilometers. The gradient within the earth is of the order of 9 degrees C per kilometer. The flow of heat from within the earth to the atmosphere would seem to be something to be reckoned with.
The Grand Poobah of AGW, addresses the media.
Good LORD! He is giving “’round the twist” a whole new meaning. (He has departed the realm of science entirely. He is beginning to give Gore a run for his money.)
Talking of Hansen, Anthony will love the March GISS:
+0.67C (from 0.26).
I remain Speechless. I bet Anthony won’t. Have a field day on it Anthony!
REPLY: Yes I saw it earlier today. Part of the problem with GISS is the way they format their raw data, which is totally different than the other 3 metrics, and makes it difficult for my plotting program to read in.
So, there is lots of manual work involved. Does anyone know of a simple way to take the left to right tabular column format that GISS uses and convert it to a more data friendly format like HadCRUT, UAH, and RSS use?
Here is the GISS raw data link
Here is the UAH raw data link
The GISS Feb to Mar temperature change is the largest one month change in the entire record based on my macro search.
Why is there such a disparity between UAH/RSS and GISS? This appears quite absurd.
Could it be heat sinks (etc.) compromising the surface stations?
UAH/RSS are satellite measurements of MW proxies and measure troposphere, not surface. GISS gets the (corrupted) surface stations.
Ian re: anna v’s 2nd law:
Even if AGW theory were able to dodge the 2nd law back-radiation would fail to produce warming of the surface.
Since Hottel (1942) the emissivity of CO2 at STP, at either 300 or 3000 ppm, has been experimentally determined to equal its absorptivity at 9*10^-4.
Asphalt’s emissivity is above 0.9 or 1000 times greater and most solids greater than 0.1. If measurement begins with the two at equal temps, the earth will always radiate heat away faster than the atmosphere can heat the surface.
If memory serves, the emissivity of gaseous H20 is about twice that of CO2.
Here is my R code for reading GISS files.
readGISS<-function(source="data/GISS.txt",temps=2:13,plot=T) {
f<-read.table(source,fill=TRUE,skip=10)
f<-f[f$V1 %in% 1880:2007,]
d<-as.numeric(t(as.matrix(f[seq(1,length(f[,1])),temps])))*0.01
ts(d,start=1881,frequency=12)
}
Well… You guys got me into a whole lot of trouble today. I made the mistake of printing out the RSS Temperature Data and hanging it on my notice board… I thought it might calm some of the loonies in the office down… you know… still a few years left before Armageddon and all that…. Stupid me… I may as well have tattooed a swastika on my head!!!!
I was informed by my Gen Y staff member that she considered this a personal attack on her and… aww… it just gets too nuts after that…. she then went off to a sustainability dinner with the rest of the staff… that I didn’t get an invite to because I’m a “Climate Change Denier”… I’m the only one in the whole place that has actually done something about reducing greenhouse gas emissions!!!!!!
You know what… I’m beginning to hope the whole thing is real…. let ’em all burn….
In the words of Mugatu…”Am I taking crazy pills or something!!!!”
REPLY: Next time try hanging garlic cloves.
Anthony
Apart from writing code I can only make one suggestion as to how you could make it a bit easier to convert the GISS data.
Excel has a wonderful function called OFFSET. It allows you set up row or column of numbers that can be used as a reference to say convert rows to columns and vice versa… Have a look in Excel help. I hope this helps….
REPLY: Thanks I’ll check that out
I wonder if it has ‘dawned’ on the sun worshippers yet that in the past two hundred years when, just by pure coincidence of course, both carbon dioxide and global temperatures have been increasing in tandem there have been several dips in temperature? Yet that was not the end of global warming, so why should anybody have ‘faith’ that the ‘end is nigh’ now?
Another half baked theory about the rise in global warming bites the cosmic dust.

REPLY: You are right about “half baked”. This study citing “Forbush increases” as benchmark for looking at cosmic ray increases is flawed. This is a short term solar event, with different energy particles mostly involved. What Svensmark proposes is a long term cycle that modulates super high energy GCM’s.
Obviously you never read the paper, you are just tossing things out.
I never mentioned Svensmark nor that some people once thought that the moon was made of cheese.
However this ‘long term’ cycle of Svensmark is just tossing things out as well.
“Anna, thank you for your discourse here. I’d also point out that Dr. Teller may very well single handedly be responsible for the demonization of coal.”
That is quite silly. The release of mercury, heavy metals, acid rain, and other factors beyond CO2 have done enough to give coal its (deserved) image as a ‘dirty’ source of energy. Plenty of environmentalists hae been after it. One factoid I remember from the 1970s that remains true is that more radioactive material is emitted from coal plants than nuclear, by a huge factor. Think radium and beyond.
but if you are into conspiracy theories, one funny thing: The “Coal is Dirty” campaign in Texas that was opposing new coal plants in recent years was underwritten by the owners of …. the natural gas power plants.
