A sea-change on climate sensitivity at The Economist

People send me stuff, today it was this “editors picks” from John Micklethwait, editor of The Economist. After years of being pro-warming, I was shocked to see this headline as a “pick”. It seems a change in editorial position may be afoot.

AGW_slowing_economist_capture

The article is quite blunt, and quite interesting for its details, here is the introduction:

OVER the past 15 years air temperatures at the Earth’s surface have been flat while greenhouse-gas emissions have continued to soar. The world added roughly 100 billion tonnes of carbon to the atmosphere between 2000 and 2010. That is about a quarter of all the CO₂ put there by humanity since 1750. And yet, as James Hansen, the head of NASA’s Goddard Institute for Space Studies, observes, “the five-year mean global temperature has been flat for a decade.”

Temperatures fluctuate over short periods, but this lack of new warming is a surprise. Ed Hawkins, of the University of Reading, in Britain, points out that surface temperatures since 2005 are already at the low end of the range of projections derived from 20 climate models (see chart 1). If they remain flat, they will fall outside the models’ range within a few years.

The mismatch between rising greenhouse-gas emissions and not-rising temperatures is among the biggest puzzles in climate science just now. It does not mean global warming is a delusion. Flat though they are, temperatures in the first decade of the 21st century remain almost 1°C above their level in the first decade of the 20th. But the puzzle does need explaining.

The mismatch might mean that—for some unexplained reason—there has been a temporary lag between more carbon dioxide and higher temperatures in 2000-10. Or it might be that the 1990s, when temperatures were rising fast, was the anomalous period. Or, as an increasing body of research is suggesting, it may be that the climate is responding to higher concentrations of carbon dioxide in ways that had not been properly understood before. This possibility, if true, could have profound significance both for climate science and for environmental and social policy.

Clouds of uncertainty

This also means the case for saying the climate is less sensitive to CO₂ emissions than previously believed cannot rest on models alone. There must be other explanations—and, as it happens, there are: individual climatic influences and feedback loops that amplify (and sometimes moderate) climate change.

That last paragraph meshes very well with recent publications about lower climate sensitivity, which they reference.

Read the entire article here: http://www.economist.com/news/science-and-technology/21574461-climate-may-be-heating-up-less-response-greenhouse-gas-emissions

While we are on the subject of sensitivity, they mention the recent paper by Nic Lewis who writes:

It even cites a paper that I’ve recently had accepted for publication, and which I think will at least get a mention in AR5 WG1.

They also have an editorial which says:

All in all, I think this is tremendous progress. Kudos to The Economist for embracing this maxim:

When my information changes, I alter my conclusions. What do you do, sir?

“Flat though they are, temperatures in the first decade of the 21st century remain almost 1°C above their level in the first decade of the 20th. But the puzzle does need explaining.”
Most of that 1 degree was built in by creative adjustments and corrections and homogenizations to the surface temperature data. The other half of the degree could very well be due to the trend of putting temperature probes nearer to buildings when they went with MMTS and electric sensors. That was a real trend, which was given short shrift by the data correctors.

Perhaps we can deal with the real world situation in the Economists home country, Britain, rather than what is happening to a hypothetical global temperature (how the notion of a ‘global’ temperature gained traction remains one of life’s mysteries)
Around 30% of the world is cooling according to BEST (but with caveats) This includes countries with some very good historic figures-Britain. This is as distinct to those countries whose figures should be taken with a large pinch of salt.
The GISS figures since 1880 can be seen as a staging post, not the starting post, of increasing temperatures which began around 1660 . Since then there have been various advances and retreats but temperatures have remained on an upwards trend for 350 years
Here are the Met office figures for Central England-the oldest such record in the world. Look at the right hand side of the graph. Either we are having another dramatic temperature retreat in the UK or it will be shown to be merely a blip in the centuries long upwards trend-who knows?
http://www.metoffice.gov.uk/hadobs/hadcet/
Statistics from the Met Office Central England Temperature Record from the year 2000 onwards show:
2000 – 2012 annual trend figures: -0.7°C
this is equivalent to almost all the agreed global warming since 1850
2000 – 2013 winter months December January February trend: -1.5°C
this is equivalent to twice the agreed global warming since 1850
Now 12 years is not an official trend but it sure is interesting, and the return of the cold has had an enormous impact on our heating bills and on our farming practices. Not 15 miles from the Met Office a farmer on Upland Dartmoor has replaced their traditional Dartmoor stock with hardier Welsh cattle as the native stock have not coped well the last five years.
Nor has the human stock. Temperatures have been plunging as rapidly as energy prices have been escalating as successive govts nonsensical energy policies come home to roost.
What is or isn’t happening with the assumed Co2/temperature correlation isn’t some academic exercise whereby climate scientists can advance alternative theories whilst the Economist observes from the sidelines.
Unless we believe that an extraordinary warming co2 bubble existed over the UK for a dozen or so years in the 1990’s which has now drifted away, surely the obvious must be faced. That is that the 1990’s were a manifestation of the long established rising temperature trend caused by natural variability. The sharp decline in the last decade is also natural variability.
We can’t predicate an insane energy policy on the notion that we must curtail co2 at any costs-including shutting down perfectly good power stations during a time of sharply declining temperatures and energy scarcity. We must predicate it on what is surely becomingly increasingly obvious-our climate is very variable naturally due to the weather extremes that constantly punctuate it.

The mismatch between rising greenhouse-gas emissions and not-rising temperatures is among the biggest puzzles in climate science just now. [paraphrased: it might mean this, it might mean that, it might mean… who knows what]
Or it might mean that the Fear Mongering Chicken Littles have been full of deception from the start, that CO2 is not connected with climate as the 3 minute video shows (as it calls out Al Gore for repeating the now retracted ipcc deception on CO2): http://www.youtube.com/watch?v=WK_WyvfcJyg&info=GGWarmingSwindle_CO2Lag
Let’s see. CO2 is rising sharply, temps are flat. And as per the video link above there is NO demonstrated causal correlation between CO2 & climate temperature. Maybe what it means is that CO2 is a dud, as is obvious from the video link above! And maybe the only reason that everyone seems all puzzled by the lack of warming is because of media hype and that 90%+ of the people haven’t got the message on CO2 that is presented in the video (so share it and spread the word about it).
The Economist. Now, that’s what is surprising. I think we have a “reputable” link now to use when we want to say that there’s been no warming for 15 years, or when we want to say that the climate models have ALL failed. That was what was said c. 10 years ago… “Do you know why we know man is causing global warming? Because the computer models prove it! And we know that there is a causal correlation between CO2 & temperatures.”

March 27, 2013 3:58 pm

This is remarkably sober and well balance. Full credit to the Economist. Their editorial policy wins though when topic get highly emotive (e.g., the build-up to the invasion of Iraq).

Well, well. While still rife with statements meant to placate the orthodoxy like,
“But that does not mean the problem is going away.”
and the final concluding non sequitur,
“Despite all the work on sensitivity, no one really knows how the climate would react if temperatures rose by as much as 4°C. Hardly reassuring.”‘
it at least is a good start in the right direction.

This isn’t a sea change, This is the same ole, same ole.

Time for a polite note discussing the reality, the magnitude, and the scope of the Little Ice Age.
Anecdote is not the singular form of data, and things like the frozen Thames aren’t “scientific measurements of temperature”. But they do highlight that the actual problematic portion of The Hockey Stick is -not- the grafted-on instruments (which, at least, have the virtue of being instruments!), but instead the shaft of the stick rewriting history.

Most journalism was and still is about fear mongering. That is what attracts eyeballs to the advertising, which is their business model.
When the AGW thingy was pushed by our media savvy Greenies, they tailor made it for journalists to have a new and easy fearmongering topic. . . . Just reprint the EcoGreenie Press releases and viola! Job done. Same logic for the politicians . . . The greenies lined up a parade of fearful citizens and politicians jumped on the AGW bandwagon and realized that leading this parade got them reelected.
And the of course we have the scientists who saw a Fame and Gravy train roll into the station and quickly realized they could keep their careers on the easy track as long as the fearmongering “science basis” of the scare was validated by their peer/pal reviewed papers.
But every Great Sky is Falling grift comes to and end and the players start looking around for the Next Great Thingy to Scare the Folks with.

I wish somebody would tell The Economist that the one-degree rise they quote is due to fiddling of the historic record. One example of across-the-board tweaking is at Iceland’s Teigarhorn station. The Jan 1900 temp was showing 0.7C two years ago, -0.2C last year, and is now showing -0.4C.

Given the Cyprus financial mess. (The Russian oligarchy who were the target of the haircut managed to spirit away their deposits via branch banks including one in the UK. info from 2 days ago and today ) I imagine the economic types really want to use anything as a diversion.
S&P has put Deutsche Bank on Ratings Watch and the Bernanke was doing a real dance around the question of can a ‘Haircut’ happen to US depositors. It was hard to find anything that was not a video but I did find a transcript HERE The Bernanke mutters something about no haircuts for depositors unless there is a run on American banks. Oh and the The ‘big five’- Brazil, Russia, India, China, and South Africa, hope to establish a new bank taking the place of the IMF and World Bank BRICS plan new 50bn bank to rival World Bank and IMF
So with all that happening in the financial world, I am sure those pulling the strings at the Economist are looking for any and all diversions. ‘Breaking News’ on climate of this sort is a good one since it hits the same group who are awake enough to question what is happening in the banking scene. So yea, the timing is rather ‘useful’

27 March: Guardian: Cold weather to continue for a month, say forecasters
UK braces for freezing Easter weekend, with temperatures expected to stay below average until end of April
by Rebecca Smithers, Tamsin Rutter and Sarah Butler
The Met Office issued a cold weather alert for much of England, with a 100% probability of severe cold weather and ice until Friday. Its outlook for Sunday until Tuesday 9 April predicts cold, dry weather, with a few light snow flurries and widespread frost and icy patches overnight. And it warned that temperatures are unlikely to recover to closer to normal levels until the latter part of April.
Ladbrokes now has a white Easter as odds-on, offering 5/1 that it will be the coldest Easter weekend ever. It has also offered odds-on of Sunday’s Oxford-Cambridge University Boat Race – last year sabotaged by a swimming protester – being disrupted by ice on the Thames…
In western Scotland, thousands endured a sixth day without power after being cut off last week, and across the UK many transport routes remained impassable because of deep snow drifts.
After embattled sheep farmers reported the deaths of thousands of lambs in snow-affected areas such as Shropshire, north Wales, west Cumbria and the Peak District, the supermarket Waitrose said that from Thursdayit would be delivering 30,000 “macs” (light plastic coats which are 100% biodegradable and recyclable) to protect lambs against harsh weather conditions to farmers it works with in Wales and the west country…
At Arthur’s Field, a 63-pitch campsite in Treloan, Cornwall, only 25 families had booked for the bank holiday weekend, but half of those had already cancelled…

You do seem to have missed one crucial element, the numerous papers which present a lag between temperature and CO2, showing it as an effect and not a cause. There have been three in the past few months alone and even Al Gore’s graph could be seen to do so when enlarged closely enough, which challenges the effect of CO2 on temperatures altogether.

I don’t see much change here. From the text:
“But given the hiatus in warming and all the new evidence, a small reduction in estimates of climate sensitivity would seem to be justified: a downwards nudge on various best estimates from 3°C to 2.5°C, perhaps; a lower ceiling (around 4.5°C), certainly. If climate scientists were credit-rating agencies, climate sensitivity would be on negative watch. But it would not yet be downgraded”

The failure of climate models is far worse than depicted by these guys using the CMIP5. What they always do is “update” the models with feedbacks that are thrown in to best replicate how the climate is actually changing. That’s not running a closed system that has any demonstrable skill in predicting climate. Just look how bad Hansen’s first forecasts were that he made when he testified before the US Senate in 1988:
http://waysandmeans.house.gov/media/pdf/111/ctest.pdf
See page 7 of this document. According to Hansen, we are supposed to be a full 1.25 degC above the thirty year mean instead of hovering around + .2 degC. To cover up this colossal train wreck, hack sites like climateskeptics.com used Hansen’s “best case scenario” GISSC and claimed it was his forecast today, when in reality version A and B are what he forecasted. The version they tried to claim was his forecast was based upon a drastic cut in CO2 emissions that never occurred. The order of the day by these clowns continues to be cover-up and deceit so that politicians can use the lies to tax and regulate.

Again, from the article:
“A rise of around 3°C could be extremely damaging. The IPCC’s earlier assessment said such a rise could mean that more areas would be affected by drought; that up to 30% of species could be at greater risk of extinction; that most corals would face significant biodiversity losses; and that there would be likely increases of intense tropical cyclones and much higher sea levels.”

If I was The Economist editor, I would have been getting rather concerned that the glaring disparity, between my ‘scientific’ opinion and the freezing discomfort of my readers as they commute their way to work through the miserable English gloom, might start to impact on the publication’s sales.
The Economist’s professed stock in trade is its ‘authority’, on all subjects, but it has been starting to look a little bit silly on this one.
Personally, I found that very little of its content actually turned out to be authoritative about events in which I was actually involved, and so I eventually gave up my subscription, because I didn’t believe them any more.
And in this case, everybody is actually involved in the events, most notably their UK readership, who will be starting to think: “This global warming-barbecue summer-never see snow again business is crap..”, as they ruin their shoes, trudging through the filthy grey sludge of Urban English snow, to sit in a freezing waiting room on a station where their train has been cancelled by ice on the conductor rail.
You can only play King Canute for so long.

Given the Cyprus financial mess. (The Russian oligarchy who were the target of the haircut managed to spirit away their deposits via branch banks including one in the UK. info from 2 days ago and today ) I imagine the economic types really want to use anything as a diversion.
S&P has put Deutsche Bank on Ratings Watch and the Bernanke was doing a real dance around the question of can a ‘Haircut’ happen to US depositors. It was hard to find anything that was not a video but I did find a transcript HERE The Bernanke mutters something about no haircuts for depositors unless there is a run on American banks. Oh and the The ‘big five’- Brazil, Russia, India, China, and South Africa, hope to establish a new bank taking the place of the IMF and World Bank BRICS plan new 50bn bank to rival World Bank and IMF
So with all that happening in the financial world, I am sure those pulling the strings at the Economist are looking for any and all diversions. ‘Breaking News’ on climate of this sort is a good one since it hits the same group who are awake enough to question what is happening in the banking scene. So yea, the timing is rather ‘useful’”

It seems that a dam has broken and everyone is talking about natural variability and natural regularities. Not long ago Trenberth denied the very relevance of the same when he called for a reversal of the Null Hypothesis. The breaking of this dam is the end of “the consensus” in what has passed for climate science.
To become a genuine science, climate science must account for natural variability and it must take as it primary goal the description of natural regularities. That description will be in the form of hypotheses, universally quantified general statements, that are well confirmed in experience. Claims about “global warming/climate change” take on significance only when presented against the background of an empirical science that comprehends natural variability.

March 27, 2013 10:44 pm

Enough talk of temperatures flattening out. That’s only the best the data tinkerers can do, to hide the decline, and it is still not so. Just ask anybody in England this year, or Queensland last year, if temps have leveled off The hell they have, and the fall in tyhem is accelerating..

A little while ago there was a similar moment in the Cholesterol theory.

This was really a clear sign that it had now arrived in the mainstream media that the world was more complicated than we had thought. This is is a similar moment in climate.

The UK has seen a drop of some 0.5degC this century! The UK’s response to temperature changes is dampened since it is a small island surrounded by water and due to the their thermal capacity they dampen the speed of change. The UK temperature anomaly is now broadly what it was in 1940.
CET is the most extensive thermometer record. Probably one of the most interesting tasks that could be undertaken is to re-evaluate CET with a view to getting a proper handle on station changes/drop outs and their effect, and on UHI and any temperature distortion brought about by UHI. It would also be a good idea to get a proper handle on error margins.
It would be interessing to isolate the best quality rural stations and look at their raw data to see what they say by way of comparator.

As a matter of logic, it is impossible to ascertain climate sensitivity until one knows the bounds of natural variation.
In order to find cliamte sensitivity, one needs to remove the noise of natural variation, and it is only once that is done that one is left with the signal of climate sensitivity.
One of the major goals in climate science ought to be the ascertainment of natural variation and its bounds.

This is very significant for the Economist considering some of the past pronouncements in the subject of climate. However, it is not fully joined up. It does not matter how much the average temperature rises. It is the impacts of that rise upon human beings and the rest of nature that should be of concern. There are two factors that are important here.
First, is that lower sensitivity will imply a slower rate of temperature rise over time for a given rise in greenhouse gases. Therefore if median sensitivity is halved, so is halved the median expected temperature rise this century. The worst alleged impacts are from destabilization of the climate system as a result of rapid change. The climate tipping points are far less likely to be breached by slower rates of warming. Along with that, it is far easier to adapt to more gradual changes. So 30cm a century of sea level rise is far easier to adapt to that 30cm a decade.
Second, is that catastrophic impacts have been over-hyped. The most costly projected impacts have turned out to be founded on little or no substance. The melting of the ice sheets is not accelerating. Crops yields will not fall by 50% in some African countries by 2020. The Amazon will not suddenly collapse from a drop in rainfall. Tropical storms are not getting more frequent or violent. Etc.
These two components of slower warming rates and the lower costs from a rise in temperature over time multiply together, to make a dramatically different picture over time.
I laid out the components to consider when assessing the expected impacts here

‘So what does all this amount to? The scientists are cautious about interpreting their findings. As Dr Knutti puts it, “the bottom line is that there are several lines of evidence, where the observed trends are pushing down, whereas the models are pushing up, so my personal view is that the overall assessment hasn’t changed much.”’
Well Professor Knutti, what it means to normal people is the consensus of eggsperts don’t have a clue what’s going on and the null hypothesis that the climate is always changing is alive and well. Naturally all those who behaved like shrieking schoolgirls with the vapours over the greatest consensus of chicken littles modern science has ever produced, need to try and extricate themselves with some skerrick of dignity and reputation intact.

CAGW is a supertanker and don’t turn on a dime but it will turn as long as the lack of warming (or cooling) continues. Secondly, Warmist orgnaisaitons & climate scientists such as the Met Office and people like Dr. James Hansen are being forced to face reality. As they say the truth will out in the end.

This small step in my view is a huge leap for the Economist. It has only been since June, 2012, that the cover story was of the Vanishing North, and a 14-page special report on the effects of global warming. This change is a major transformation in a short time.

The Economist’s penultimate paragraph reads:

As a rule of thumb, global temperatures rise by about 1.5°C for each trillion tonnes of carbon put into the atmosphere. The world has pumped out half a trillion tonnes of carbon since 1750, and temperatures have risen by 0.8°C. At current rates, the next half-trillion tonnes will be emitted by 2045; the one after that before 2080.

I thought there were “diminishing returns” from the addition of CO2. Is this paragraph a blunder?

Also from The Economist, regarding Freeman Dyson:
“The same deep dislike of intellectual overconfidence has led Mr Dyson to challenge the received wisdom on climate change. Mr Dyson is not a climate sceptic; he concedes that Earth is warming and that man is responsible. But ever since he first tinkered with computer models of climate in the 1970s he has repeatedly found them so wanting as to make their dire projections worthless.”

According to the Economist:
“One type of model—general-circulation models, or GCMs—use a bottom-up approach. These divide the Earth and its atmosphere into a grid which generates an enormous number of calculations in order to imitate the climate system and the multiple influences upon it. The advantage of such complex models is that they are extremely detailed. Their disadvantage is that they do not respond to new temperature readings. They simulate the way the climate works over the long run, without taking account of what current observations are. Their sensitivity is based upon how accurately they describe the processes and feedbacks in the climate system.”
The Economist’s account of models is the most sophisticated that has appeared in popular media but it contains a crucial error.
What the Economist has right is that GCMs imitate the climate system. In other words, a GCM is an attempt to reproduce, in a computer, the workings of the climate. In addition, the Economist is right that the models do not take account of observations.
What the Economist has wrong is that the models describe the processes and feedbacks in the climate system. Models do no such thing. Models imitate the processes and feedbacks but do not describe them. If the models described them then modelers could produce from model code the physical hypotheses that describe the relevant natural processes. Modelers cannot produce those physical hypotheses. Modelers create mathematical equations, not physical hypotheses, which take numbers as inputs and produce numbers as outputs. Modelers then interpret the output numbers as the effects of one or another natural process. However, any such work depends on modelers’ intuition and not something that can be shared and tested against reality the way that physical hypotheses can be shared among scientists. The “climate sensitivity” assigned to any model cannot be something different from the modeler’s intuitions about the model.
GCMs reproduce reality but do not describe it. Models imitate natural processes but do not describe them. Physical hypotheses describe natural processes but do not imitate or reproduce them. GCMs are not comparable to physical hypotheses. Only physical hypotheses can be confirmed or disconfirmed through experience. These facts are the reason that GCMs do not take account of observations. In principle, GCMs cannot take account of observations. The use of GCMs should be limited to analytic work and they must never be used as substitutes for physical hypotheses.

“All serious climate scientists agree on these two lines of reasoning. But they disagree on the size of the change that is predicted.”
“…a small reduction in estimates of climate sensitivity would seem to be justified”
“Since CO₂ accumulates in the atmosphere, this could increase temperatures compared with pre-industrial levels by around 2°C even with a lower sensitivity and perhaps nearer to 4°C at the top end of the estimates. Despite all the work on sensitivity, no one really knows how the climate would react if temperatures rose by as much as 4°C. Hardly reassuring.

Regardless, something that is unlikely to change is their advocacy for better market based approaches to reducing emissions (ie, a simple carbon tax) instead of cumbersome regulations and trading systems.
