UAH global Temperature for December – no change

UAH Global Temperature Update for Dec. 2011: +0.13 deg. C

By Dr. Roy Spencer

The global average lower tropospheric temperature anomaly for December, 2011 remained about the same November, +0.13 deg. C (click on the image for the full-size version):

The 3rd order polynomial fit to the data (courtesy of Excel) is for entertainment purposes only, and should not be construed as having any predictive value whatsoever.

Here are the monthly stats for 2010 and 2011:

I’m making very good progress on the Version 6 of the global temperature dataset, and it looks like the new diurnal drift correction method is working for AMSU. Next is to apply the new AMSU-based corrections to the older (pre-August 1998) MSU data.

[Reminder: Since AMSR-E failed in early October, there will be no more sea surface temperature updates from that instrument.]

To Dr. Roy Spencer (or anybody else who can answer these 2 questions).
1) Does the satellite data include both the North Pole and South Pole temperature readings?
2) If the answer to 1 is yes, does James Hansen uses this information when he creates his global warming maps that show massive warming in the Arctic?
(I’m curious as to where he gets his temperature data from since there aren’t a whole lot of temp sensors in the Arctic).
================================================
Kramer, I’m not an authority, but my understanding is no to number 1, but gets close. However, relating to the previous post, I recall Dr. Christy cautioning on the use of sat data above a certain northern latitude. (80°?) As to Hansen, he uses either a red or pink crayon, and extrapolates and interpolates numbers…… mostly from the GHCN, using land based temp reading.
I’ll look for the Christy statement, as I recall, it was here that he made that statement.

My memory may be going, but its still better than ok. Here’s Dr. Christy’s words……

As the spacecraft rolls over the pole it does so at an inclined orbit so that the highest nadir latitude is about 82 deg with the scanner looking out a bit closer to the pole. Since we apply the scan line data mostly to the nadir area directly below the satellite, the actual data only go to about 83 deg. In the gridded data I interpolate over the pole, but I wouldn’t trust the data too much beyond 85 deg.

We may be in a La Niña based on ocean temperatures but I’m not sure this is a normal one. The SOI has been fairly quiet compared to what it could be. As such I don’t think there’s a huge pile of warm waters in the PWP. I have no idea what this might mean. Has anyone seen any discussion of this anomaly?

“That you are not openly laughed at here for saying such a thing only shows what low standards of “science” are maintained here.”
============================================================
No, it simply shows that most here aren’t as boorish as others are willing to display. And, if anything, its says volumes to your scientific knowledge. You can make snide comments but you can’t respond to the two very simple statements he/she made? And then you snark about the standards here? phhttt.

Alex;
Save up to 40% on heating/cooling by using a small fan in the corner with the flow directed or bounced up to the ceiling. Forces mixture of cool floor and warm ceiling air, and vastly improves comfort levels. The architectural version is a hollow corner column with openings top and bottom and a small internal fan, but the DIY version works fine; I’ve used it non-stop for over a decade.

GSW It is just as fallacious to assume a linear trend rather than any kind of curve when it comes to climate.
===============================================
CCT, many use a linear trend to note what has and is happening, not what will happen. There’s a huge difference between using a linear trend line for clarity vs using it as some sort of predictive mechanism. Fact is, no one really uses R² for predictive purposes.

January 3, 2012 7:52 pm

James Re “Fact is, no one really uses R² for predictive purposes.”
My only comment is that Nicola Scafetta appears to use some cyclic trend (presumably a sinusoidal fit) for predictive purposes – apparently with good accuracy …he says:
“An empirical model based on these cycles can reconstruct and forecast climate oscillations.”
This, I believe, will become “standard” in the future for long-term climate predictions.

According to the NWS, an interesting heat-wave has hit Alaska an hour ago. Within two hours the temperature in Healy Alaska jumped from -35F to +172F.

Meanwhile, in the past hour, a strange cold-wave grips Hawaii. In 48 minutes the temperature in Kaneohe fell from 77F to 40F according to the NWS.

There is a data point in early 1983 that is hotter than the last 2 months, some 28 years hence.

As has been pointed out numerous times, the measurement of SST’s during ENSO cycles in general tells out only how much net energy is leaving or remaining in the surface layer of the oceans, and in general, more net energy is stored in the ocean during a La Nina. If we are measuring anomalous heat at the surface of the ocean that is a sure sign that the atmosphere is about to get warmer as that heat being measured is being transferred from ocean to atmosphere. Though of course, skeptics are quick to find all sorts of reasons why Ocean Heat Content estimates must be inaccurate, in fact they are the best metric for really seeing what the true energy being stored in the upper layers of the ocean is doing. It goes up during most La Nina’s, and this latest one is no exception. In general the oceans have given up less energy than they’ve taken up over the past 30 years or so– meaning that El Ninos have not released as much energy as has been stored during La Nina’s.
Also one comment about Dr. Spencer’s “entertaining” 3rd Order Polynomial Fit. It truly does of course mean nothing at all, and I suspect, in the next few years, if Dr. Spencer retains it, it will be even more than obvious that it means nothing.The current peak in the 3rd order polynomical fit is gettting a bit “long in the tooth” (i.e flattening), and the next move in the 3rd order polynomical, as the current La Nina fades and some of that energy is released back to the atmosphere, could be up.

Well, James Hansen – he of NASA-GISS “fame” and to the media’s democrat-socialist party leading “authority” on CAGW – claims his mid-1980’s paper on temperature trends allows him to extrapolate temperatures over a 1200 km distance based on HIS single paper’s 0.44 r^2 calculated value…..

1.   Gather available data
2.   Homogenize
3.   Adjust for proper slope
4.   Extrapolate
GSW says:
… You can’t get a sine wave from a third order polynomial and you should not ‘anticipate’ a cyclical temperature signal from the ‘fit’ shown.
Still looks like a 3rd order polynomial sine wave with a 60 year period.

R. Gates says – “Ocean Heat Content … goes up during most La Nina’s, and this latest one is no exception.”
So, given that September 2011 values were about the same as those in 1963* we can expect a decline in (so-called) OHC when we get past the current La Niña – that’s good!

It is made up from a few (a VERY few) land stations up to 1200 km away from that cell. It is entirely a work of mathematical fiction based on something they call “The Reference Station Method”, that has been “pal reviewed” in a very narrow set of conditions, then applied in far broader context, and recursively, with ever less ‘related’ stations.
I’ve read (and run) the code.

E.M Smith..
Seeing you have seen the code, and run it, do you have any guesstimate of the probable error range…. (I’m thinking +/- 15 C or even more)?
Is that related to same one mentioned above, with an R2 = 0.44 ? (ie basically useless)

Oh, and please everyone.. ignore the 3rd order polynomial, its just a pretty curve, and totally meaningless. (sort of like straight lines are meaningless wrt climate.).

Sometimes these threads are like a game of telephone. My argument was with the word “stubbornly.”

January 4, 2012 5:14 am

So where does that put 2011 historically? I haven’t seen any news articles about it being the Xth warmest year so it can’t have been too bad. I can tell from the chart above that every month of 2011 was cooler than its respective month in 2010. But I’m still half expecting to come across an article talking about how this was still a warmer than average year and how all of the Y warmest years have occurred in the last Y years.

Comparing UAH and GISS Arctic temps between 1999 and 2010, GISS get an increase of 0.69C greater than UAH.

For all the naysaying, claims of meaninglessness or entertainingness, etc., made for it above … that 3rd order polynomial fit gets to look a better fit with every passing month. Even if it should “really” be a 60-year sine wave.

Not likely. The longer- term trend seems to be that the oceans are simply not releasing as much energy during El Ninos as they are taking up during La Ninas cycles. Given that the current cool phase of the PDO favors more La Nina episodes versus El Nino, the oceans don’t seem primed anytime soon to be suddenly releasing all this heat. Some of the energy is of course released during El Ninos, and will be during the next one, but no where close to the kind of additional heat content that has been added over the past 30+ years.

In general the oceans have given up less energy than they’ve taken up over the past 30 years or so–

Sufficient data do not exist do draw that conclusion. We don’t have one decade of ocean heat content data, let alone three.
The current peak in the 3rd order polynomical fit is gettting a bit “long in the tooth” (i.e flattening), and the next move in the 3rd order polynomical, as the current La Nina fades and some of that energy is released back to the atmosphere, could be up.
Uh, when a third order polynomial peak “flattens”, it is approaching an inflection point, and the trend is about to head the other way. You’re better off with the “that third order polynomial fit doesn’t mean anything” tune from your “whistling in the dark” repertoire.
