As pointed out last week, Sea Surface Temperatures and the daily lower troposphere temperatures continue to fall as La Niña looms large in the Pacific. We may find that the continued drop prevents 2010 from being the “hottest year ever” that many alarmists are hoping will to put some life back in the climate change meme.
Dr. Roy Spencer reports:
As the tropical tropospheric temperatures continue to cool, the global average is finally beginning to follow suit:+0.42 deg. C for October, 2010. This is the lowest monthly temperature anomaly we’ve seen in what has been a very warm year.

For those following the race for warmest year in the satellite tropospheric temperature record (which began in 1979), 2010 is still within striking distance of the record warm year of 1998. Here are the 1998 and 2010 averages for January 1st through October 31:
1998 +0.57
2010 +0.54
Note that the difference between the two is not statistically significant…just symbolically.

OT, to my many Northern Californian brothers and sisters who follow WUWT.com closely — or, as in Anthony’s case, actually run it — congratulations to the SF Giants.
I remember driving home from Candlestick, windows open wide on the freeway in the cold and fog at midnight to keep Dad awake, under strict orders to yell if he nodded off. Way to go Giants!!!!!!!!!!!
Truth be told, I feel the same way about La Nina preventing the takeover of western economies by those with hidden agendas.

An oddly compelling note, Harold. Says so much beyond the acual words used. Nice!
What is the difference in measurement between this data and the graph at http://processtrends.com/images/RClimate_UAH_Ch5_latest.png where the MTD for october is 0.221 (at 29-10)?
It’s now 2nd November 2010, Australia. Daily highs for the last few weeks have been 4-6c below average for this time of year. Summer officially starts on 1st of December and predictions are that November will be cooler and wetter than average.
What goes up must come down. The higher the rise the lower the fall. Natural variability will find the mean. I expect the fall will be great as La Nina, solar impotency and higher volcanic activity delivers their blow.
I am not optimistic about La Nina’s ability to prevent Californians from committing economic suicide tomorrow.
Hey Patrick Im still waiting for spring – seems like winter is still around – it was 13d c the other day in Sydney and cold. As for the sun most of what we seem to get is rain. All this is to be expected from natural climate cycles – oh and a cooling sun – but I blaspheme!

I too am happy about the Giants. But La Nina or no La Nina, the way the propositions are worded on the ballot this time around is troublesome. Prop 23 might go down, and California’s struggling economy with it. That one is a tightrope.
So, not having Nov and Dec 1998 anomalies close to hand, what does 2010 need the next two months to stay under them?
Is this before, or after, the data has been “Hansenised”? (:-
33 in Perth right now, 36 tomorrow – way above average and not a drop of rain to be seen. Is that significant? Nah, I don’t think so, it was bloody cold here this winter, way below average – so what is more important, warmer or colder? Depends on if you’re drinking wine or beer 😉
Harold Ambler- I froze my arse off in the upper stands at Candlestick-in August!
Good game though, been a Giants fan for years, nip and tuck with the Mariners….

If the Giants can win the big one, then another miracle could happen and California Voters will get smart tomorrow, else it’s the brick wall behind door #23.
Contigo no problemo. The AGWers will just continue in their pattern of El Moreno until the dominant El Culo phase is over.
I’ve posted the preliminary October (Reynolds OI.v2) SST anomaly update:
http://bobtisdale.blogspot.com/2010/11/preliminary-october-2010-sst-anomaly.html
The data for October won’t be official until next Monday, but the preliminary (based on an incomplete month) shows a sizable drop in global SST anomalies.

Nov 1998 came in at 0.19 for an eleventh month average of 0.54. This November will need to come in at 0.54 to equal the 1998 eleventh month average.
Patrick Davis/Twawki – so you think it was a miserable October in Sydney?
Well, so do I, and so do the other 4 million people in Sydney, or at least all those I’ve spoken to.
But according to climatological method, we’ve all been sweltering in the furnace of climate disruption.
The BoM summary at least tells it like it was, meteorologically:
http://www.bom.gov.au/climate/current/month/nsw/sydney.shtml
“Little sunshine, cool and wet.” (The least sunny October on record at Sydney Airport)
No argument there.
But it goes on to say: “The average maximum temperature at Sydney Observatory Hill was 22.0°C which is slightly below the historical average of 22.1°C…”
and: “The average minimum temperature was 14.9°C, which is above the historical average of 13.5°C…”
Now, because an entire month’s weather is reduced to a single number – (average maximum + average minimum)/2 – for GISS/HadCrut to calculate anomalies and plug into the laughable ‘Global average temperature’ construct, Sydney will show as having an anomaly for the month of +0.65C.
So how about that? While we all thought we were having a crappy month, it turns out that we have just experienced the equivalent of a century of global warming.
Little sunshine? Cool days? Less night-time temperature drop?
Personally, I blame the clouds. Now remind me again please, someone, what is the least understood and most ineffectively modelled climatic factor?
Full observations for the month are here: http://www.bom.gov.au/climate/dwo/201010/html/IDCJDW2124.201010.shtmlractions
So I am wondering if anyone has ever done any research on the following topic…
CO2 has a logarhythmic radioabsorptive property in the atmosphere (as the ppm increases, the warming from each unit of increased concentration is decreased… see the graph posted on this site approx 25x a year… it’s helpful.)
Water is a much more prevalent GHG, comprising both the majority of the GHG effect, and a much larger (but significantly more VARIABLE) portion of the atmosphere.
The GHG effect of water is most easily compared by looking at a tropical locale and a desert locale. Both are hot, experiencing a high amounts of direct sunlight. The striking difference between the two is (of course) the available atmospheric water vapor levels. Tropical regions are typical at or near absolute humidity, desert regions are usually very low humidity. This isn’t absolute, but it’s a pretty accurate description of either a causative or correlative condition. You don’t have the capacity for extensive biomass found in tropical regions without adequate supply of fresh water. Likewise, if there was a significant amount of available water, it wouldn’t be populated with only species capable of surviving in conditions with very little rainfall and little available river/lake/ground water supplies.
During the night, WETTER environments hold on to their heat quite thriftily, maintaining warm temperatures through the majority of the night. In part, this is likely related to the energy donated by condensing water as the temperature drops down to and then below the temps needed to maintain daytime absolute humidity levels. Meanwhile, in the drier regions, the swing between night and day is much larger, comprising blistering hot days with cool to cold nights.
This blanket effect seems to be largely driven by water vapor, logically, given that there’s no real convincing method available for CO2 to “give up” it’s heat in exchange for a phase transition, and energy MUST be maintained.
Where does this thought process lead me to… This article!
As we enter a strong La Nina, a significantly large portion of the Pacific Ocean is now a few degrees colder than usual at the sea surface. This suppresses local evaporation at the boundary and leads to decreased overall local water vapor concentrations and a lower absolute humidity. With a few points off the absolute humidity, the night time temperatures can drop a few degrees further before being buffered by the necessary condensation of water vapor to continue cooling.
Hence, the LOCAL environment over the La Nina areas are going to tip a bit more towards the “desert” side of the equation. Whereas higher SST during an El Nino are going to feed more water vapor, meaning higher abs. humidity and a higher temperature buffer.
Has anyone considered this as a possible vehicle for the rapid temp drop we’re seeing now? Anyone know of any research articles looking into local absolute and relative humidity versus day/night temperature anomalies? We may find that the much decried “increasing night time temps” that we hear so much about isn’t all UHI and could be related to an increasingly moister world (leading to wonderful things like the greening of the Sahel).

Base periods are different. The official UAH MSU record uses 01.1979-12.1998 as a base period, while the graph in question only shows the measurements made by AQUA since 2002.
The graph in question h
I suppose I should clarify. My tropics/desert comparison was used to look at (comparatively) the effects of water vapor on temperature retention. It seems like a very simple concept, but I haven’t seen anyone reference this effect when talking about changes in night-time air temperatures, only UHI vs CO2.
I am NOT in any way, comparing the WAY that the two get their relative water vapor concentrations… there are multiple theories on how forests stay humidity (e.g. biotic pump theories), or grow where rainfall occurs due to natural geographic formations. But the effect of heat capture can be felt even in open areas in tropical environments. Anyone in Florida can tell you how well the night times retain their heat, compared to a much more arid environ like the Mojave.
I grow tomatoes in my back yard in sydney it is so cold they are not growing. to all global warmers out there tomatoes don,t grow in cold weather, so pray we don,t go into a ice age you will all starve good luck
Let me try to explain this from the warmist perspective. This unexplainable downtrend is only temporarily negating the much more explainable and disastrous uptrend. Once this unexplainable cooling is over, the explainable warming will continue worse than we thought. Dare I say unprecedented?
“Nov 1998 came in at 0.19 for an eleventh month average of 0.54. This November will need to come in at 0.54 to equal the 1998 eleventh month average.”
This is not correct. 1998 first 11 months: (.57(10) +.19)/11 = .535
2010 first 11 months: (.53(10) + X)/11 = .535
X=.485 : So Temp for Nov needs to be <.485 to be behind 1998 which looks good with La Nina.
