Second warmest Autumn on record
Autumn has turned out to be the second warmest on record, beaten only by autumn 2006 on a Met Office dataset that dates back to 1910. November itself was also narrowly pushed into second place, only beaten by November 1994.
More impressively, based on the much longer CET dataset, which has run since 1659, provisional figures also show that autumn and November were the second warmest on record.
Locally, Linton on Ouse had their warmest November on record.
It was also very dry in eastern areas, with Coningsby in Lincolnshire and Leconfield in East Yorkshire both experiencing their driest November since records began.
The exceptional November ends a very interesting 12 months across the UK, which has seen extremely polarised weather condtions at times.
December 2010 was the coldest since 1890, and the second coldest on record (CET dataset which began in 1659). April 2011 was the warmest on record; with the UK breaking its October record for the highest temperature recorded both locally and nationally.
As we begin December, the jet stream is exactly where it should be at this time of the year, with westerly winds set to continue.
This means any cold snaps are likely to be short lived.
More importantly the much hyped extreme cold and snowy weather, forecast by several private weather companies for December, seems as far away as ever.

Hello, I’m Paul Hudson, weather presenter and climate correspondent for BBC Look North in Yorkshire and Lincolnshire. I've been interested in the weather and climate for as long as I can remember, and worked as a forecaster with the Met Office for more than ten years locally and at the international unit before joining the BBC in October 2007. Here I divide my time between forecasting and reporting on stories about climate change and its implications for people's everyday lives.

Whether you're trying to predict the weather through probablistics, a la Met Office, or historic patterns, a la Piers, the inherently chaotic nature of the climate and our fundamental lack of understanding of its condition and drivers will always mean that, in the absence of anything material to depend upon, every mid/long-range forecaster is at the mercy of *luck*. Nobody makes a successful long term forecast of this chaotic system through good management more than they do through good fortune, no matter what they claim.

Based on the final AQUA CH5 temperature, the UAH figure should be +0.101c, but the actual figure could be 0.1c lower or 0.07c higher.

I am surprised that you have adopted this argument, since you must be aware that astrology is based entirely on the position of objects in the solar system relative to a notional zodiac of 12 constellations and that there is no physical mechanism for the alleged influence of those objects.
On the other hand, I believe that Corbyn's predictions are in part based on the effects of electro-magnetic radiation from the sun.
So while I am myself sceptical about Corbyn's ability to predict the weather using his methods, I do think that they have a much stronger scientific basis than astrology.

On what basis do you say that 2010 tied with 1998?
According to the CRU, the annual HadCRUT3 anomaly for 1998 was 0.548c and that for 2010 was 0.478c, i.e. 0.07c lower. In fact, by this measure, 2010 was only the third warmest year, after 2005 with 0.482c.
Even the MO "provisional" figure, issued in January 2011 made it the second warmest.
https://www.metoffice.gov.uk/news/releases/archive/2011/2010-global-temperature
Also, you seem to be saying that individual nations or regions cannot have climates, but the planet has long been divided into various climatic types, including the Temperate climate, which includes the UK.
One definition of climate is "The meteorological conditions, including temperature, precipitation, and wind, that characteristically prevail in a particular region", so the climate of the UK would be defined by the long-term averages of these conditions.
For the purposes of measuring "climate change", the period over which the averages are calculated seems to be 30 years, but IMHO, that is too short.
Also, there can be large variations in the weather within the average climate, which do not constitute "climate change".

Thanks QV. I've recovered somewhat since the work's party yesterday evening. (There 'is' a Piers Morgan somewhere, isn't there?)
On the astrology thing: the idea of linking Corbyn's methods with astrology struck me at an unsteady moment, you might say. But I don't think it's too outrageous.
Classical astrology might be based on zodiacal planes, etc , but at least part of its interpretation has always been to presume to be able to predict the distant future by interpreting 'signs' allegedly coming from the stars. We can forgive this notion in ancient cultures. But what about modern ones?
The truth is we don't know the scientific basis of Corbyn's claims, because they remain unpublished. So when he predicts weather with pinpoint precision (but not necessarily with pinpoint accuracy) weeks in advance, is he making a scientifically-based claim or is he star gazing?
The person we hear most often praising Corbyns' success rate is Corbyn. He claims on his site that his predictions have been refereed in the scientific peer reviewed literature, but I can't find any links there (though I find links to many other things, such as subscription offers).
Perhaps I've underestimated him though. Maybe tonight's snow skiff where I live is just the leading edge of the month-long reign of cold and heavy snow that was supposed to start the best part of a week ago. Or maybe it's just a brief December cold spell?

As far as I am aware, astrological predictions are based entirely on the relative positions of the planets (and possibly other phenomena such as comets), in relation to a notional zodiacal constellations (not the actual constellations), and doesn't involve the stars themselves. As far as I am aware, no physical force has ever been specified which causes the influence of the planets. So I still think that whatever method is used by Piers Corbyn, it would be wrong to compare his methods with astrology.

Again, just coincidence I think.
However, since a reversal of the Earth's magnetic fields is now overdue, if that were to occur, it would put the theory to a test. However, I suspect that there may be other effects with greater impacts.

It demonstrates how quickly things can change in the British Isles, simply as a result of a variation in atmospheric pressure patterns.

One thing which has annoyed me recently is that prevention of "climate change" has been the main reason put forward for not destroying the rain forests. The implication is that were it not for "climage change", destroying the forests would be o.k. As you imply, I think that preserving the forests and the habitats the contain should be an end in itself and shouldn't rely on the implications for the climate.

Should we be trying to stop the use of trees from the Amazon forest? Trees have a limited life, 200-400 years or so, but the Amazon forest has been in situ for millions of years. It is subject to natural devastation like wildfires, floods, landslides, etc and recovers without our input. In fact our input might not be the best thing for the forest since we still do not understand the area very well. It is also a resource that the local peoples can use to earn a living to feed themselves and families. A renewable resource which the likes of WWF and Greenpeace want to be a political hot potato to get some people to give them money for the 'fight'

Also, the Continental USA anomaly is up from -0.077c to +0.327c, i.e. a rise of 0.526c relative to the NH as a whole. This seems to point to a continuation in the rise of land temperatures relative to sea temperatures.

I wouldn't say overdue.
A bit later than recently, possibly due to the weekend.
The conversion to 1961-90 is a bit controversial, and some would argue that it is not possible to do that accurately, since the satellite records don't start until 1979.
The base period for RSS is 1979-98, which has a zero mean anomaly (as you would expect), and the mean HadCRUT3 anomaly for that period is about 0.147c, so I add that to the RSS to get the equivalent HadCRUT3 figure, but it may not be completely accurate.
Incidentally, did you know that the mean HadCRUT3 anomaly for 1961-90 is approximately -0.0277c, the mean HadSST2 is -0.0375c, and the mean CRUTEM3 is +0.00367c, when they should in theory all be zero?
In theory, you have to adjust the current anomaly figures by the above figures, in order to get the true anomaly relative to 1961-90.
The difference in the case of the HadCRUT3 anomaly is equivalent to an individual month being 10c too low, or an individual year being 0.8c too low.
The 30 year period over which the HadCRUT3 anomaly has a near zero mean is actually December 1964 to November 1994. When I pointed out the discrepancy in the HadCRUT3 figure to the MO, and pointed out that the mean NCDC and GISS anomalies over their base periods was zero, I received the following reply:
"NCDC and GISS both use a certain amount of data interpolation in order to estimate temperatures in areas where no observations were made. In producing HadCRUT3 we do not do this. The data coverage changes from month to month and from year to year. This has two effects. The first is that it that there are uncertainties in the climatological average particularly in data sparse regions. The second effect is that the changing coverage combined with changes in the climate during the climatology period mean that the average of the anomalies is not exactly equal to zero."
Personally I don't find this a satisfactory or verifiable explanation.

While that's certainly true it doesn't offer any explanation for the changes observed over the past few decades. Climate changes only when it is 'forced' to do so.
There are viable explanations for what these forces were in the past, including changes is solar output, convergence of warm/cold configurations in earth's long-term orbital cycles, the weathering of silicates due to mountain formation, volcanic activity, meteor impact, increases in vegetation, decreases in vegetation, changes in ocean circulation due to tectonic movements, etc, etc...
It's not as though all these things haven't been considered as explanations for the recent observed warming. They have. They don't fit the evidence; at least not by themselves. Increased CO2 concentrations from fossil fuel combustion, combined some of these other forcings fits the long-term evidence very well. That is the conclusion of every major national scientific academy on earth.
It doesn't mean there isn't some other forcing that is as yet un-described. It just means it is considered, by over 95% of scientists currently publishing in this field, to be the best explanation currently available.

The wife in the analogy clearly identifies that the last data point is a 'typo' mistake by the husband.
"You can see that the final number isn’t right. You must have written it down wrong — it’s simply an error... [she] enlarges her latest photo (she has all the digital images) and is able to read the correct height from the image — those Nikon cameras are awesome! She corrects the final data point."
She corrects the final data point *then* subtracts 2 cm from each measurement for which the child wore shoes.
I'd say Tamino is referring to the GWPF graph that purports to show no warming in the "last 10 years" of the BEST data.
As Tamino and others showed, the last two data points on the graph the GWPF published had very low confidence values and should have been ignored. They also used a period of several months less than 10 full years, which also reduced the slope of their linear trend.
I agree it's not a perfect analogy, but none are. Yes, the child will only ever grow at that age (hopefully). And if the shoes represent warm periods like El Ninos, then there should also rightly be a little trough for the child to stand in occasionally to represent La Ninas.
But I think it's ok, and I think if you re-read it you should see the context of the final data point discrepancy.

And our climate models did not forecast it, even though man-made carbon dioxide, the gas thought to be responsible for warming our planet, has continued to rise."

Thanks, I must wait until I wake up in the morning before reading such articles.
"I'd say Tamino is referring to the GWPF graph that purports to show no warming in the "last 10 years" of the BEST data.
As Tamino and others showed, the last two data points on the graph the GWPF published had very low confidence values and should have been ignored. They also used a period of several months less than 10 full years, which also reduced the slope of their linear trend."
So because the latest figures are low, they must be ignored?
Just because a figure has "low confidence", does that make it wrong and too low?
Surely it is just as likely to be too high?

I can only repeat what I and several others have repeated here many times: since 1988 at least the WMO have been recommending the use of 30 years of continuous temperature data to identify underlying climate trends.
When you look at the last 30 years of data in all five of the global data sets, which includes satellites, the trend in all of them is +0.17C per decade warming, +/- 0.01C.
It has been repeatedly shown that decade-long periods of stasis or even reduced temperature trends can occur within long term periods of warming: https://www.skepticalscience.com/pics/SkepticsvRealistsv3.gif
This might be the start of a period of cooling, or it might just be yet another one of those periods of stasis.

The reply said that "half of the years in this decade will be warmer globally than 1998", but didn't refer to the years 2010-2015.
I have sent a reply requesting clarification on whether that prediction still applies.

Firstly, do you accept the logic of the analogy, i.e. that the end data point was a typo, rather than a problem with the shoes?
Second, the BEST data for April and May 2010 disagrees strongly with the land data from all the other providers: https://www.woodfortrees.org/plot/best/from:2008/offset:-0.6/plot/crutem3vgl/from:2008/to:2010.42/offset:-0.4/plot/uah-land/from:2008/to:2010.42/offset/plot/rss-land/from:2008/to:2010.42/offset:-0.14
Tamino pointed out that the confidence values BEST attached to the data for these two months was ten time lower than the lowest confidence value attached to any other single month in their entire series.
They should not have been published. But they suit the GWPF case so they used them happily without so much as mentioning their low confidence rating.
They also referred to their graph as "the last 10 years" when it fell several months short of a full ten year period.

Not really, unless the anomalous temperature figure can also be proven to be a typo, although I admit that one figure (April?) does look odd.
I am afraid that I haven't really being paying much attention to the "BEST" data situation.
Where did that April 2010 figure come from? I thought that "BEST" were using data which was available from other sources.

Just briefly, as I'm supposed to be doing something else (!), I seem to remember that the last two months' data from BEST that you are referring to were actually only based on a small number of stations rather than the complete global data set. This explains both the much lower confidence limits and the sudden apparent drop in temperature. You are certainly correct to say that they shouldn't have been published in that form.

Has it been peer reviewed and published yet or are we still looking at the pre-report?
I seem to remember that at the time of the release, BEST were suggesting that the record would change (cool) once the sea area was included. Moreover, the Watts issue still hasn't been fully resolved so I'm sure he will have more to say on that. I see that Mosher and Co have recently put a paper together dealing with UHI and the like. It's not getting much attention due to the emails I guess.

BEST is still in review. I'd expect the last two data points to be removed by review, but we'll see.

Yes, but according to NASA, the mean anomaly for 1998 was 0.56c, that for 2010 was 0.63c, and that for 2005 was also 0.63c, so 2010 tied with 2005, not 1998.
Also, according to NOAA, 1998 was 0.6217c, that for 2010 was 0.6435c, and that for 2005 was 0.6413c, so while 2010 was almost identical to 2005, it didn't tie with 1998.
By saying that 2010 tied with 1998, making it the warmest year, you were sort of implying that you were referring to HadCRUT3 which had 1998 as the warmest year. If 2010 had tied with 1998 based on NASA & NOAA, it wouldn't have been the warmest year by those series.
On the figures from NASA and NOAA, both organisations have 2005 as the second warmest, not 1998.

Maybe Dr. Spencer is thinking up an excuse for the lack of a substantial drop in the November temperatures.
So far in December, the AQUA CH5 anomaly is back up above the "average" for this time of year, the figure at the end of November and even that for the end of October.
The cumulative December temp. so far is equivalent to a UAH anomaly of about 0.12c
