UAH is out, like RSS it is down a bit

Although the webserver file for the UAH dataset has not been updated yet, the man who is “in the know” because he’s a major part of the process has released the December UAH global lower troposphere temperature anomaly value. It is 0.18°C down from .254°C the previous month.

2008 10 0.166

2008 11 0.254

2008 12 0.180

Here is what Dr. Spencer had to say on his website today:

uah-dec-2008

Latest Global Average Tropospheric Temperatures

Since 1979, NOAA satellites have been carrying instruments which measure the natural microwave thermal emissions from oxygen in the atmosphere. The signals that these microwave radiometers measure at different microwave frequencies are directly proportional to the temperature of different, deep layers of the atmosphere. Every month, John Christy and I update global temperature datasets that represent the piecing together of the temperature data from a total of eleven instruments flying on eleven different satellites over the years. As of 2008, our most stable instrument for this monitoring is the Advanced Microwave Sounding Unit (AMSU-A) flying on NASA’s Aqua satellite.

The graph above represents the latest update; updates are usually made within the first week of every month. The smooth curve in the graph is a fourth-order polynomial fit to the data, which smooths out the large amount of monthly variability in the data and helps reveal the underlying ‘trends’. (There is no claim that this curve has any predictive power for the coming months or years.)

Keith,
They are not recomputing the baseline every month. But every month has its own baseline.
Does that make sense?
For example, for calculating the anomaly for January, it has a baseline that is a twenty year average — 1979-1998 — for January. Similarly, the baseline for July will be a twenty year average for July. Now the actual average represented by the zero line for July is going to be higher than what the zero line represents for January. Do you follow?
But as to your primary interest in knowing where we are now with respect to a baseline that includes the last ten years — and HadCRUT, GISS, and UAH/RSS all use some baseline ending in 2000 or earlier — your best bet is to follow the data at
http://discover.itsc.uah.edu/amsutemps/
The particular series I look at daily is “ch 5” (14,000 ft/4.4km/600 mb):
http://discover.itsc.uah.edu/amsutemps/execute.csh?amsutemps+002
Using the default plotting options, you see a 20 year average (which I take to be the most recent 20 years, not a baseline like 1979-1998), a plot for last year, and then this year. You’ll see that for last year, temperature tended to fluctuate around the 20 year average through August, and then stayed above the 20 year average for much of the rest of the year.
Is that the kind of information you are looking for?

Dude, you’ve had two ice storms already and will likely have another hard freeze on Saturday (watch those pipes)! Maybe that’s normal for Dallas…
Yes, we have had an unusually early start to winter this year. But that’s just weather, no? Question is: How much “weather” does it take to make a “trend?”
Much more interested in where we’re all headed over the next 10 years. Warm, wet and well-fed is much preferred to cold, dark and hungry.

I personally believe that the politicians will be the last, with the exception of the eco fundamentalists, to realize there is no global warming long after that the MSM has flip flopped and made it a joke.

“Hence, if we would cut down emissions in a few decades – which is very likely as alternatives fuel becomes economically viable”
There is currently no “alternative” fuel that I am aware of that would cut CO2 emissions. The only fuel that would cut CO2 emissions that I see available is nuclear generated electricity.
But one must wonder why we even need to cut CO2 emissions. Warming is better than cooling. A warmer planet would make for a more diverse biosphere. Current IPCC predictions of environmental response to CO2 increase has been shown to be greatly exaggerated. If we doubled the CO2 in the atmosphere from pre-industrial levels, we would get less warming than we had from natural causes in the 18th century. It would get lost in the noise of natural variability. I see no reason to worry greatly about CO2 emissions.
What is important is that things such as mineral petroleum is too valuable a resource to simply burn up. When we run out of oil, we run out of plastic, paint, fertilizer, computers, televisions, and fibers for clothing. Conserving our petroleum resources will become an important issue but not because of CO2 emissions. It will be important because of all the other things aside from fuel that it is used for. The same applies for coal.
Nuclear energy with recycled fuel is our most environmentally friendly way to provide an inexpensive, large scale energy source that can power a global economy for centuries to come and still leave enough of our mineral petroleum resources to make the other materials we need in a modern society.

Piers Corbyn has actually placed a £100 bet on this happening. This does bring Corbyn’s judgement into question since, whatever happens to global temps in 2009, the global warming (climate change) issue isn’t going to go away any time soon. It’ll be at least 5 years – and probably nearer 10 – before there’s any shift in government thinking.
If Corbyn wants a more sensible bet why doesn’t he approach James Annan or George Monbiot. If he’s just looking for publicity he’ll get it with Monbiot.

Have no idea where to post this but I found it very odd.
http://www.eponline.com/articles/70183/
NASA did a 5 year study and came to the conclusion that clouds associated with severe storms are increasing do to global warming.
Two things I found odd about the conclusion
#1 – How come a 5 year study is okay if it backs up their claim, but an 11 year study of lowering temperatures is not long enough
#2 – Temps have decreased in the last 5 years not increased so if their study found more clouds associated with severe storms wouldn’t that mean they are increasing do to global cooling and not warming

“There is currently no “alternative” fuel that I am aware of that would cut CO2 emissions”
Actually, Crosspatch, there is a very viable alternative that would immediately cut CO2 emmissions. It’s called a worldwide economic recession.
But you are correct in pointing out the other benefits of fossil fuels. Occaisonally, when I’m feeling mean, when I come across a really strident AGW proponent I tell said person that if they are really interested in lowering thier carbon footprint they should advocate the boycotting of the Internet. The Internet itself is very, very ungreen. Besides the plastics, poisonous materials used to manufacture microchips, PCB boards, transformers, and LCD screens, the Internet is a huge drain on our power supplies. I point out the KW usage of a typical Google data center (I currently work in IT), not to mention data centers hosted by AT&T, Time Warner, Yahoo, and any number of Fortune 500 companies.
I tell my AGW proponents that they could do more by boycotting the Internet than any other activity. Of course, most of these AGW types live online and would the Internet would be the last thing they give up. Well, maybe not the last thing; they also love thier $4.5 Starbucks lattes.

Jared,
The key detail in that is that the study looked at correlation between seasonal variation in clouds SST’s and clouds, and then went on to extrapolate a secular rise storms based on a presumed “present rate of global warming of 0.13 degrees Celsius.” That’s pretty close to the number we get from a simple linear fit through the UAH satellite temps, but as we all know the actual rise has been nowhere near that for some years now.
I haven’t looked at the underlying research, and am not a meteorologist or climatologist, but I might question whether the atmospheric-ocean dynamics that give rise to seasonal (annual) variations necessarily hold true for secular (longer term) changes in SST’s occasioned by other factors (regardless of what they are).

@MikeD
The 4th order polynomial is a troublesome line. I just don’t like it, as pure data mining and especially with some conditional knowledge. What I see is a cyclic (sinusoidal) pattern with a frequency that varies from 3.5 to 4.5 years and with an amplitude of about 0.6 degrees C.
Whenever I look at any site, pro or anti Global Warming, I always get given a trend picked with some different start date to illustrate a point. One can make good cases for current temperatures trending up or down…
When I look at the data, I don’t see trend lines at all. I see step functions. Ignoring known perturbations, I see temperatures from 1979-2001 as flat, with a small dip in 1985. Then climbing from 2001-2003. Then flat from 2003-2007, then dipping from 2007-2009. So that’s 20 years of flat with a 5 year elevated spot.
My prediction, which is worth nothing at all, is that we’ll now get 20 more years of flat (that is, variation between +0.2 and -0.2), with a small dip somewhere….

There is currently no “alternative” fuel that I am aware of that would cut CO2 emissions. The only fuel that would cut CO2 emissions that I see available is nuclear generated electricity.

Substantially true. Especially given the quantities involved. The tonnage of coal and oil burned each year makes any talk of an alternative fuel a bit laughable. You would need to find one heck of a lot of something to make it from.
With that preamble, there are in fact contenders. But you said ‘currently’ and that means sooner than a half decade or two from now…
The best quasi-non nuclear option is coal derived fuels using nuclear process heat (as worked on by VW engineers in the ’70s) where about 3/4 of the energy comes from nuke, transported in methanol from coal as the carbon source. One could use trash, trees, etc instead of coal, if desired.
The major contenders for fuel are algae & cellulose. There are startup stage companies working in those area, but not much production. VRNM Verenium and Poet (private) are doing cellulosic ethanol Real Soon Now and both Origin Oil (OOIL) and PSUD (Petrosun Energy?) are doing algae. PSUD has started contracting for ponds in Texas, so is closest to “production”. There are a couple of others, too. But the ramp up to ‘size’ will take years and years even after shown to work commercially.
If you want just energy and not fuel then you can look at things like electricity (but that gets into “fleet change” and a decade+ lag, so isn’t current either…). Hydrogen is just a chemical battery of sorts, not an energy source and just about everything you can use to make hydrogen is better used directly as a fuel or to make electricity.
What is important is that things such as mineral petroleum is too valuable a resource to simply burn up. When we run out of oil, we run out of plastic, paint, fertilizer, computers, televisions, and fibers for clothing.

Um, not really… While this is often said and widely believed, the realitiy is that any carbon feedstock can be used. It’s an economic decision, not a technical one. Coal and plants were the original ‘petro’chemical feed stock and they are starting to be again. Examples?
Eastman Chemical EMN makes “petro”chemicals from coal today (they never bothered to swap from coal in the first place a gob of decades ago… coal was used long before petroleum…) Most U.S. chemical companies (like DOW and DD Dupont) use natural gas feed stock and have since the Arab Oil Embargo of the ’70s. Rentech RTK has demonstrated making fertilizer and other chemicals from coal or trash via gasification to “producer gas”. The biggest chemical, plastic and resin maker in South America, Braskem BAK uses sugar cane and sugar cane alcohol to make plastics and resins. Oh, and there is a company in the midwest making plastics from corn… Natureworks? Yes: http://www.natureworksllc.com/
http://jscms.jrn.columbia.edu/cns/2005-03-15/russell-cornplastic
Corn plastic became big business in 1997, when Dow Chemical, the plastics giant, and Cargill, an agricultural company, formed a new company, Cargill Dow, to develop the material. Cargill bought out Dow’s interest in the joint venture in January and renamed the company Natureworks LLC.
Oh, and Sasol SSL in S.Africa use coal for their “petro”chemicals. And there are undoubtedly others too. Heck, I’ve made nitro-cellulose from cotton (as was used in early billiard balls and photographic films ‘nitrate stock’) and rayon is also made from cellulose. The first president of Israel was a chemist who developed a system using a bacteria to make several alcohols and acetone prior to cheap oil:
http://en.wikipedia.org/wiki/Clostridium_acetobutylicum
There is much active work today to use bugs to get chemicals… and fuels. British Petroleum BP is building Butanol factories for fuel production from plants, though I’m not sure what method they use. Once you have an alcohol you can make it into anything organic… (Butanol is nice because you can drop it into a gasoline tank and just drive away… no conversion needed. See: http://www.butanol.com where the guy uses a different bug/process.)
And with this, I’m going to stop. If I didn’t this would get waaaay too long. (Alternatives for fuels and plastics is one of my tech hot buttons… I’ve only spent about 40 years fascinated by it…) Suffice it to say there is never going to be a shortage of plastics, fertilizers, chemicals, polymers, resins, etc. due to feed stock depletion.

Oh I can’t resist… One more…
Almost all plastic and organic chemical synthesis starts (or can start) with ‘synthesis gas’ CO + H2. (Guess why it’s called synthesis gas…) If you have CO2, you can make syngas via a hydrogen from water. Just add water and a lot of heat to CO2 and you can get synthesis gas. (Some added C helps but there are ways around that).
What this means is that as long as there is CO2 and energy there is chemical feed stock… Think about it… Now realize that we have tons of CO2 produced from rocks when we make cement and other products. Even if we didn’t use plants, we can still get CO2 from dirt, especially limestones.
This is ‘part 2’ of my no limits to growth mantra. Part 1 is there is no energy shortage and never will be. Then, as long as you have energy there is no shortage of syngas, which implies no shortage of non-metal materials. Since we can get metals from sea water and rocks with energy, you end with no shortages of stuff. Ever. The key is unlimited energy from nuclear and the sun. Since with energy and materials we can make lots of greenhouses and desalinizers food and water are not limiting either.
This is why I say:
We run out of energy when we run out of planet. AND
We run out of materials and plastics when we run out of planet. AND
We run out of food when we run out of planet.
It isn’t a question of technology development, only price. And that is why I’m generally positive about our future prospects. The only shortage is of imagination and will.
