HadSST3 selectively removes the majority of the long term variations from the pre-1960 part of the record. ie. it removes the majority of the climate variation…
…that cannot be attributed to anthropogenic global warming!

Actually, it’s much more than a problem of physics. It has vast policy implications.
If models are not useful in a decadal timescale, such as they can predict a strong warming for a period of minimal or even no warning, then what use is there for models? What government (apart from North Korea…) would make it difficult for people to heat up their homes in the next decade with the explanation that is going to be warm in 2070 anyway?
People do not average-out their lives across decades or centuries: each and every one of us have to go through each and every day first.
If I freeze to death today at -10C, I will not enjoy the warmth of July at +30C even if the average is +10C, perfectly compatible with human life. The same can be said of plants and animals. If I plant an olive tree in my London garden, it will die of cold in February even if the yearly average is in theory just enough to make olive trees survive in the open. If a nasty mosquito species migrates from warmer places during an August heatwave, still if that species cannot survive the following winter it will not be around until next migration opportunity during a future heatwave.
A purely statistical, multi-year approach to modelling the climate is in theory useless for policymaking (similar considerations could be made for non-regional projections, but that is too long a story here – read “How Space-Time Digested AGW” if interested). And if we end up with 15 years of incorrect projections without even a volcano for an excuse, then whatever physical explanation there is, policymakers would be much wiser in keeping climate scientists at arm’s length.
The Missing Heat of homeo-climate-path Kevin Trenberth is not just a matter of increasing the number of measurement points. Something else is…amiss.
As noticed by David Whitehouse of the GWPF for quite some time (my emphasis):
In the past decade the atmospheric CO2 levels have increased from 370 ppm to 390 ppm and using those figure the IPCC once estimated that the world should have warmed by at least 0.2 deg C. The fact that the world has not warmed at all means that all the other climatic factors have had a net effect of producing 0.2 deg C of cooling.
But there is more. The counterbalancing climatic factors have not only compensated for the postulated AGW at the end of the decade they have kept the global annual average temperature constant throughout the past 10-15 years when the AGW effect wants to increase it. The key point that makes this constancy fascinating is that for every value of CO2 there is an equilibrium temperature that is higher the greater the concentration of CO2 in the atmosphere. In other words, the higher CO2 concentration at the end of the decade exerts a stronger climate forcing than at the beginning of the decade.
This makes what has happened in the past decade all the more remarkable. Because the greenhouse effect wants to force the temperature up which in the absence of a cooling influence is what would have happened, the fact that the temperature has remained constant indicates that whatever has been cooling the planet has had to increase in strength at precisely the same rate as the CO2 warming in order to keep the temperature a constant straight line.
This means that for 10-15 years the combined effect of all the Earth’s climate variability factors have increased in such a way as to exactly compensate for the rise in temperature that the increased CO2 would have given us. It is not a question of the earth’s decadal climate cycles adding up to produce a constant cooling effect, they must produce an increasing cooling effect that increases in strength at exactly the same rate as the enhanced greenhouse effect so as to keep the earth’s temperature constant.
Can it really be the case that over the past 15 years the sum total of all the earth’s natural climatic variables such as changes in solar irradiance, volcanoes, the Pacific Decadal Oscillation, the North Atlantic Oscillation, and the Arctic Oscillation, all of which can change from cooling to warming over decadal timescales, have behaved in such as way as to produce a cooling effect that is the mirror image of the warming postulated by the anthropogenic climate forcings from CO2 and other greenhouse gasses, from the changing water vapour, from tropospheric ozone, and from a clearing aerosol burden?
This can be visualized as following. Imagine there is a quantity ExpT that can be computed beforehand (x(t)=x(t-1)+0.1) (blue in the graph). Consider also the actual measured MeasT values (y(t)=0.5*rand()) (red). Fix x(0)=y(0)=1 and plot their evolution (and divergence).
Now, of course DiffT=y(t)-x(t) (yellow) becomes increasingly larger as x(t) increases whilst y(t) hovers around 0.5. A centered running 5-point average AvgDiff5Cent (green) will mimic ExpT, entering progressively more negative territories. In fact the correlation between AvgDiff5Cent and ExpT is for all intents and purposes, one.
So if ExpT is going up because of CO2 emissions, what kind of magic is intervening to generate the AvgDiff5Cent counterforcing so that the total is zero on a decadal timescale? (And yes, the small small small amount of warming actually reported should obviously be taken as close to undetectable, ie zero).
Even if we had perfect 100% coverage of the whole planet, this question would remain open.
I’m sure Kevin “saying it is natural variability is not an explanation” Trenberth understands this point. It’s a case of missing physics, more than heat.
(Just noticed Judith Curry has hit on the same nail – great minds really think alike )
(I have left this comment at Andy Revkin’s “A Legal Defense Fund for Climate Scientists”)
Andy – I’m very surprised by the phrasing of your FOI question. So what if there is “fishing” involved?
The important bit about FOI is that it applies no matter what the intentions of the requester are.
Otherwise every Government agency will always argue FOI exemption by claiming the requester is “fishing” for information. And especially so if the requester is a journalist (who is presumed to be looking for something to publish, therefore pretty much single-mindedly interested in “fishing”).
Intention-dependent FOI is not freedom, rather a gracious (and always temporary) concession on the part of the State. It’s like trying to define as democratic a Parliament you can vote for only if invited to the electoral polls.
Are you sure decades of struggle to get FOI in place should be considered as wasted just to defend publicly-funded scientists who can’t understand their rights and duties, and pretend FOI is a waste of time when in reality it’s a clerical activity?
ps I’ve been subject to FOI In the past and anything I write at work can potentially be used in a court of law
UPDATE: For those interested in abrupt climate changes of the past
I recently surmised Peter Gleick be an astroturfer trained to make greens look less than…bright. This article would be compatible with that hypothesis, as the author shows no grasp of the history of climate, including what are known as Younger Dryas and the PETM.
It should also be obvious to all that the longer we look in the past, the lower our ability will be to discern one decade from another, and then one century from another. The climate might as well have changed dramatically every year a million years ago, still the paleo traces will only show some kind of long-term average of it.
We cannot seriously compare contemporary records with those of the past without considering that. It would be like saying more things happen now than in the Middle Ages just because more people write now than in the Middle Ages.
The continuous mentioning of the fabulously flawed 97% figure (it’s 97% of 77 out of 1,372) is just the cherry on the cake. Is Exxon funding the Pacific Institute?
Climategate 2.0 is helping filling some knowledge gaps, for example in the way the IPCC has been slowing killing itself, and several thousands humans to. The following concerns Regional Projections, and it’s a tragedy of communication.
Willingly or not, the IPCC has become a source of deadly confusion exactly because it has provided the information its audience wanted, even if it was scientifically unprepared to prepare that information.
I have a confession to make…it ain’t much fun to talk climate change at a time where AGW and especially Catastrophic AGW are taking blows left, right and center. So in order to keep this blog lukewarm, here’s a heartful “thanks!” to New Scientist for providing the context for planetary temperatures so far:
And yes, our current climate WARMING catastrophe is at the bottom right.
I’m sure you agree–the Mann/Jones GRL paper was truly pathetic and should never have been published. I don’t want to be associated with that 2000 year “reconstruction”.
And here it is: “Global surface temperatures over the past two millennia” aka “Mann, M. E., and P. D. Jones, Global surface temperatures over the past two millennia, Geophys. Res. Lett., 30(15), 1820, doi:10.1029/2003GL017814, 2003.”
We present reconstructions of Northern and Southern Hemisphere mean surface temperature over the past two millennia based on high-resolution ‘proxy’ temperature data which retain millennial-scale variability. These reconstructions indicate that late 20th century warmth is unprecedented for at least roughly the past two millennia for the Northern Hemisphere. Conclusions for the Southern Hemisphere and global mean temperature are limited by the sparseness of available proxy data in the Southern Hemisphere at present.
Reconstructions of hemispheric mean temperatures over roughly the past two millennia employing proxy surface temperature data networks with sufficient spatial and seasonal sampling, temporal resolution, and retention of millennial-scale variance, support previous conclusions with regard to the anomalous nature of late 20th century temperature at least about two millennia back in time for the Northern Hemisphere. To the extent that a ‘Medieval’ interval of moderately warmer conditions can be defined from about AD 800– 1400, any hemispheric warmth during that interval is dwarfed in magnitude by late 20th century warmth. The sparseness of the available proxy data in the Southern Hemisphere lead to less definitive conclusions for the SH or global mean temperature at present.
One can slice and dice trends at will about the latest RC silliness…it doesn’t matter. Radiative effects are negligible in the troposphere, and heat waves are a matter of weather, not statistics.
Take for example the recent mild UK weather. OF COURSE CO2 has nothing to do with it. Temperatures are higher than normal because southerlies bring warm air over from France. A proper analysis of October/November trends (and we did have quite a few very cold days already) would have to include a research on wind patterns.
Anything that doesn’t, it’s pseudoscience.
Climate science — or at least some parts of it — seems to have devolved into an effort to generate media coverage and talking points for blogs, at the expense of actually adding to our scientific knowledge of the climate system
Actually, it was December 2009 when I wrote in the pages of the Spectator (UK):
This might be the most important lesson of the 1974 report on global cooling: that we need to grow up, separate climatology from fear, and recognise — much as it pains politicians and scientists — that our understanding of how climate changes remains in its infancy.
Here we are, almost two years later. For example, what do we understand about the past? Willis Eschenbach at WUWT shows it in the non-smoothed BEST reconstruction graph:
And what do we understand about the future? Patrick Frank in Skeptic.com’s Reading Room:
In other words: for the past, all we know for sure it’s that the error bars cover from -5C to +3C if we go back to 200 years ago. For the past, all we can estimate for sure it’s that error bars cover an enormous span if we move forward 100 years (even removing cloud uncertainty, still the 2100 error goes from -10C to +16C).
For all we know, Romans were conquering a world that was 50C colder than today, and oceans will boil before the XXII century. Or vice-versa.
Please do not start speculating about uncertainty as a reason for doing nothing – it isn’t.
Think of science instead: what’s the way out of this cul-de-sac made up of giant error bars? How can our understanding finally leave its infancy? The way out has actually being indicated already, by a guy born in 469BC:
Socrates was wise in that he knew the he knew nothing, whereas others were unaware of their own ignorance.
If and when such a realization will become widespread, only then climate science will be able to mature away from silly manipulations, towards the approach so nicely described by Professor Sir Bernard Lovell to David Whitehouse:
One evening we unrolled the pen recorder data in a long ribbon down the corridor outside the main observing room. “Now,” he said, “look at the data. Get to know it.” His point was that before us was what the universe was saying, and that it was more important than any theory.” Data is never inconvenient. It beats theory every time.
An unexamined climate is not worth studying…
I surmise that the four pre-pre-pre-papers will get torn to pieces in the next few days (here’s my biting off the UHI article, followed by Steven Mosher’s). The quality of the BEST work will be measurable in the way they will react to that ( (a) making the necessary adjustments, (b) ignoring the lot, or (c) circling the wagons).
The jury is still much out. In the case of Anthony Watts, so far it’s been a strong (b). Assuming B.E.S.T. is not a collection of unprofessionals, such a reaction makes little sense.
OTOH we do not even know if B.E.S.T. is really about science, or something else. As I commented at Judith Curry’s blog:
Read what you write Judith! A PR strategy! Did Bohr have a PR strategy, or Maxwell, or Dirac.
The BEST PR strategy is not the best PR strategy because it became so important as to become visible. It’s THE news, as you can read at WUWT. And a total failure: science takes once again the back seat, and who cares if BEST does it for visibility rather than politics?
Your results and your work have just been buried by your team. Congratulations! /sarc
No placebo pill will ever work if it’s got “PLACEBO” written on it: likewise, no PR strategy will work if it’s so much in-your-face to its potential audience.
UPDATE: I guess it’s GENERAL CIRCULATION Models (not “Global Climate Models”) and never again will I trust a journalist (when did I say that already… ) –
From MarsDaily (links added by me):
New analysis of data sent back by the SPICAM spectrometer on board ESA’s Mars Express spacecraft has revealed for the first time that the planet’s atmosphere is supersaturated with water vapour.
[…] descriptions of the vertical distribution of water vapour – a key factor in the study of Mars’ hydrological cycle – has generally been based upon global climate models. This gap in the data has now been addressed by the SPICAM (Spectroscopy for Investigation of Characteristics of the Atmosphere of Mars) imaging spectrometer on Mars Express.
[…] Surprising new results [published in this week’s Science], based on SPICAM data obtained during the northern spring and summer, indicate that the vertical distribution of water vapour in the Martian atmosphere is very different from previous assumptions.
[…] Until now, it was generally assumed that such supersaturation cannot exist in the cold Martian atmosphere: any water vapour in excess of saturation was expected to be converted immediately into ice. However, the SPICAM data have revealed that supersaturation occurs frequently in the middle atmosphere – at altitudes of up to 50 km above the surface – during the aphelion season, the period when Mars is near its farthest point from the Sun.
Extremely high levels of supersaturation were found on Mars, up to 10 times greater than those found on Earth. Clearly, there is much more water vapour in the upper Martian atmosphere than anyone ever imagined. It seems that previous models have greatly underestimated the quantities of water vapour at heights of 20-50 km, with as much as 10 to 100 times more water than expected at this altitude. […]
UPDATED: Sort of a confirmation for the below as Hanlon at the Daily Mail has posted an article where HarperCollins, the publishers of the Times Atlas Greenland fiasco, try to argue that they only depicted white the areas with ice>500m thick.
Strange things are always afoot, in matters of climate.
Incredibly, and despite having been shown the wrongness of their ways from multiple and even warmist sources, a spokesperson from the £150-a-piece Times Comprehensive Atlas of the World still maintains their debunked “AtlasGate” Greenland map is correct:
“But a spokeswoman for Times Atlas defended the 15% figure and the new map. “We are the best there is. We are confident of the data we have used and of the cartography. We use data supplied by the US Snow and Ice Data Centre (NSIDC) in Boulder, Colorado.”
As the story unfolds, I would like to point to something about the new map that is strange indeed: the level of detail. See for example this comparison from Real Science:
There are two possible interpretations for that: either some people at the Times Atlas have decided to reinvent the world adding fantasy features to a previously fully white map; or, much more likely, they have used some other, existing map of Greenland, embellishing to conform to the Times Atlas style.
In fact, and intriguingly, and twice embarrassingly, there exists one map that strongly resembles the Times Atlas’ “15%” Greenland (see also the Greenland Physical Map from TourTeam.dk). And the embarrassing bits are: it’s one map used on Wikipedia. Worse, it’s supposed to be only showing ice sheet thickness, not “cover” as claimed (it doesn’t highlight the areas where the ice is less than 10m/30ft thick).
Look for example at the outline of Eastern sides of Kong Christian IX Land and Kong Christian X Land, the nearest to Iceland (brown on the Times Atlas to the left, green on Wikipedia to the right).
Look now at the Times Atlas’ Greenland map of 1999 (below, to the left) and the fact that their 2011 map (center) is so much alike the Wikipedia Greenland ice-sheet thickness (right) becomes even more evident.
So the following series of events is consistent with the observations:
Now where’s the evidence for it? Where is it indeed, as Michael Corleone would have asked.
This doesn’t look like a good way to enhance the reputation of a publication like the Times Atlas. As usual, it’s the stubborness of their response the real problem, perhaps even more than the original error. One is left wondering how many more mistakes have been made (perhaps them too, miraculously similar to maps posted on Wikipedia), mistakes simply too small to immediately notice. And the publishers and editor will never admit one anyway.
Averages can only tell you so much, and that’s quite little. As “global warming” is based on worldwide averages, it should be then always looked at judiciously and with a good deal of curiosity to figure out what is happening above and beyond the simple figure that is an average temperature.
Say, one lives in Placeville, a town where it’s -20C in January, +20C in July. Average is zero C (32F).
Imagine now, winters warm by 10C, summers cool by 5C. So it’s -10C in January, +15C in July. Average is 2.5C (36.5F).
Headline news: “Placeville heavily hit by global warming, average temperatures up by 2.5C“. When the real-life news is, it’s much cooler than before: still very cold in January, and now not even warm in July.
This is such a simple concept, I am always amazed how many people don’t get it. But then few grasp the most elemental aspects of statistics. And I wish three people in the world understood what “global warming” might be about.
Seems like global warming is such a primary point of concern, satellites vital for its study always get booked on dodgy rockets, with predictable results.
Bye bye Glory? In truth, it’s not “climate science” that will suffer from the loss. It’s climate modelling. Because, as in previous circumstances, with an operational lifetime of 3 years instead of 30, Glory was not meant to study the “climate”, rather to provide supplemental information to climate models.
And that’s no “Earth observation”.
For as long as predictions will be difficult, especially about the future, “denialism” will as a matter of course remain appropriate only in the context of past facts, i.e. in the “denial” that they actually occurred.
So let’s set aside the widespread, idiotic name-calling against anybody having any question regarding impending climate catastrophes: because the real Climate Deniers are very easy to spot.
And it’s the people that to this day still live in the fantasy world where Climategate was a non-event and had no consequence (esp. on the science of climate change). You know, the people that haven’t read Andrew Montford‘s GWPF report, or the findings of the Muir Russell review, or Lord Oxburgh’s comments about reconstructing temperature trends for the past 1,000 years (Q36 in the link) (or, erm…my preface to the Italian translation of Montford’s report).
Or they have read the lot, but due to their denialist attitude they can’t fathom the meaning of what’s written in there.
Everybody else might have instead noticed by now that a major. widely-funded, “independent, replicable, inclusive, transparent…approach [to] estimate…global temperature change” (and “the uncertainties in the record“) is expected to come to fruition sometimes next year. And yes, Climategate had an important role in getting Berkeley Earth Surface Temperature (BEST) up-and-running.
QED…all those labelling of non-believers as “deniers” has simply been a kind of preventative attack. And finally, it has backfired.
ps my predictions on the BEST results:
What else has changed?
Well, one thing is that at the time, Walter Sullivan of the New York Times could still afford to write “Other Specialists See No Thinning of Polar Ice Cap” in mid-size letters near the title. As for the rest:
However, there are other interesting details:
TerraDaily reports today of Jeffrey Kiehl’s “Lessons from Earth’s Past“, actually published by Science magazine a month ago. A cursory reading is what is needed to understand how flawed Kiehl’s whole idea is, of focusing on a question like:
when was the last time Earth’s atmosphere contained as much carbon dioxide as it may by the end of this century?
(Kiehl’s answer: 35 Million years ago)
How flawed is that question? Very, very flawed. For the geologically-challenged readers of this blog, here’s an in-depth commentary of Kieh’s rag(*) by Doug L. Hoffmann at Resilient Earth, summarized by this quote:
All of the factors outlined above clearly point to the fact that geological forces, operating over tens of millions of years, caused Earth’s climate to cool dramatically during the past 35 million years. Claims that the cooling was caused by a reduction in atmospheric CO2 have been refuted by many. Studies of the Late Ordovician glaciation found that, without orbital forcing, ice sheets can grow with CO2 levels as high as 10 times preindustrial atmospheric level. Yet Kiehl maintains this fiction to the end, even to the point of reintroducing claims based on computer models.
People that don’t believe in geology and are obsessed with temperatures can limit themselves to Wikipedia’s helpful graph “65 Million Years of Climate Change“, showing high temperatures around 35 million years ago indeed. But when seen in context, the 35Myr point is part of a whole different story than “CO2 concentrations driving the planet’s temperatures“: it was the end of the Eocene and of a steady decrease in temperatures, the time of the Antarctic glaciation and a brisk decrease in temperatures, the start of relatively cool 10 million years (still, warmer than today) etc etc.
And so Kiehl’s context-free “it’s all CO2” work ends up looking like a tirade against people driving on a motorway at 70mph, written by somebody obsessed with analyzing what happens when people drive at 70mph, yes, but in a crowded market.
Science, it ain’t: it’s just ever-the-misnomer “Science” magazine.
(*) poetic license taken
In 1930 of course.
This is getting boring. Seemingly all one has to do in order to find instances of past climate change, totally invalidating the “unprecedented” claim attached to today’s, is to guess the right combination of words for this or that search engine.
AGWers should have tried earlier, in the age before the Internet, when fantasies such as labeling any unusual weather pattern as “anthropogenic” would have been easier to maintain.
As I get labeled “most controversial” (thank you, whoever), let me mention a perfect yet extraordinary example showing how any claim, however far-fetched and based on little or no science at all, can be dressed as the latest scientific warning about impending doom caused by humanity’s excesses, without of course anybody involved showing any sign of critical thinking.
I am talking about the “Guardian news” (from Sep 12, 2007) that “man-made chemicals [should be] blamed as many more girls than boys are born in Arctic” (that is, twice as many girls as boys). This is specific to the Guardian as every other link I have found about it, can be traced back to a Paul Brown reporting from Nuuk, Greenland, that
Twice as many girls as boys are being born in some Arctic villages because of high levels of man-made chemicals in the blood of pregnant women, according to scientists from the Arctic Monitoring and Assessment Programme (Amap)
[…] The scientists measured the man-made chemicals in women’s blood that mimic human hormones and concluded that they were capable of triggering changes in the sex of unborn children in the first three weeks of gestation. The chemicals are carried in the mother’s bloodstream through the placenta to the foetus, switching hormones to create girl children.
This would have been an incredible finding, shattering a lot of established ideas on the roles of chromosomes in humans. And it was picked up as such by treehugger.com (no comment) and a scienceblogs site called (the irony!) “Island of Doubt“. Its author James Hrynyshyn wrote on Sep 13, 2007, that the news was “not good“, proceeding then to equivocate when pointed out how outerwordly it all sounded.
What makes this all exemplary is that it would have taken just a few minutes to figure out the holes in the story. First of all, the “findings” were:
“disclosed at a symposium of religious, scientific and environmental leaders in Greenland’s capital, Nuuk,…organised by the Patriarch of the Orthodox Church, Bartholomew I, which is looking at the effects of environmental pollution on the Arctic.“
More importantly, there was very little about the “findings” in the AMAP communications at the time (and even less, today). The 2006 State of the Arctic Environment Report (SOAER) says nothing at all about skewed sex ratios. An AMAP report from 2001 titled “Human Health” mentions two works by Mocarelli and others showing a change in the boys/girls ratio due to exposure to dioxin by the fathers (and so it would have nothing to do with the Guardian’s claim)
Mocarelli P, Brambilla P et al. Change in sex ratio with exposure to dioxin. Lancet 1996; 348: 409.
Mocarelli, P., P.M. Gerthoux, E. Ferrari, D.G. Petterson, S.M. Kieszak, P. Brambilla, N. Vincoli, S. Signorini, P. Tramacere, V. Carreri, E.J. Sampson, W.E. Turner and L.L. Needham, 2000. Paternal con- centrations of dioxin and sex ratio of offspring. The Lancet 355:1858-1863
There is also an AMAP report from 2000 (mentioning the excess girls as per the Mocarelli’s studies, but also the absence of such an excess in a similar situation in Taiwan). An AMAP poster from 2002 mentioning a decrease in the number of male newborns in whales (from 56% to 44%, far far less than what claimed about humans).
What would explain the enthusiasm leading to the…unorthodox announcement at the Orthodox Church symposium rather than through the usual scientific channels (or even, an official press release), is the AMAP report from 2006 saying that “Two new special projects have been initiated: one investigating contaminants in relation to sex ratio (based on the results from the PTS report)“. Hoever, in the Conclusions and Recommendations of the PTS report one reads something extremely vague:
Statistically significant associations have been found between blood concentrations of total PCBs (Arochlor 1260), lead and a number of non-specific reproductive and developmental health effects such as the prevalence of low birth weight, premature births, stillbirths and major structural malformations. Serum concentrations of total PCBs in maternal blood also appear to be associated with impacts on newborn sex ratios.
Anybody with a half-curious mind would have also read the literature mentioned by AMAP, for example this article from 2006, “Pathways of endocrine disruption during male sexual differentiation and masculinization“, where the abstract ends:
There is currently no definitive evidence that exposure of humans to environmental chemicals can induce testicular dysgenesis and/or impair masculinization, though pathways via which this could potentially occur are established.
It should have gone without saying that even if AMAP had found that “definitive evidence“, of course they wouldn’t just have seen two girls for every boy, but an enormous number of boys with various degrees of “endocrine disruption“.
There’s more, thanks to our hindsight of 2011. Of course the Guardian article has never been followed by any update (you know there’s something particularly fishy when all mainstream media but one refuse to report a story). How about AMAP? Here’s from their 2009 report, with some added emphasis:
POPs exposures have been suggested as the reason for observed alterations in birth sex ratios in animal populations and occasionally in human studies. New research results with pigs, which have a similar reproductive system to humans, indicate that exposure of sperm to environmentally pertinent organochlorine mixtures in vitro adversely affects oocyte development, polyspermy, sperm fertility and embryonic development. However, a comparison of existing population studies, one including Arctic countries, did not reveal any definitive or consistent relationship between POPs, sperm X:Y ratios or male:female birth ratios. Emerging data from a larger cohort in the Russian Arctic indicate that increasing maternal PCB concentrations may be associated with an initial effect of increasing the male:female newborn ratio; however, causality has not been determined and the increase in the ratio appears to disappear in the highest concentration group. The possible effects of other contaminants have not been determined. Systematic epidemiological studies, including all possible confounders and other relevant contaminants, must be performed before any conclusive statements can be made about contaminants and sex ratios in Arctic populations
[…] Results from the INUENDO study…This study indicates that POP exposure might be involved in changing the proportion of ejaculated Y-bearing spermatozoa in human populations. Inter- country differences, with different exposure situations and doses, may contribute to varying Y:X chromosome ratios. However, the higher proportion of Y sperm did not support the observed increase in the female:male ratio reported previously
[…] In general, no definitive conclusion could be drawn from these studies. Emerging data from a larger cohort in the Russian Arctic indicate that increasing maternal PCB concentrations may be associated with an initial effect of increasing the ratio of male:female newborns. The Russian results appear to confirm the trend reported in the previous AMAP Human Health assessment (AMAP, 2003); however, causality has not been determined and the increase in the ratio appears to disappear in the highest concentration group
Good luck with finding any of that in the Guardian. In the meanwhile, the initial rubbish gets repeated verbatim, for example in a highly-praised book by Sara Wheeler, titled “The Magnetic North” and reviewed with the brains fully shut by Holly Morris for the New York Times:
One boggling case in point: “Endocrine-disrupting chemicals handed up the food chain have triggered changes in the sex of unborn children in the first three weeks of gestations, resulting in the birth of twice as many girls as boys in some villages in Greenland and among the Inuit nations of eastern Russia.”
No prize if you notice the full certainty of Wheeler (and Morris): HAVE TRIGGERED CHANGES. I am sure AMAP has written to the New York Times protesting already.
They’ve got incredible supercomputers to play with, but still our climate scientists build up global anomaly charts from only a handful of stations (1,000 or so if the guys at Climate Monitor are not mistaken, or one on average for every area the size of Bangladesh).
You’d think world-rescuing climate specialists would have computers and bandwidth enough to handle data from a million stations by now, or a billion even. But they say they don’t even need that.
Why not? Because they have discovered that 1,200-km grids are ok. Why are they ok? Because
temperature anomaly patterns tend to be large scale
How so? Here’s the root of it all, from 1987:
The 1200-km limit is the distance at which the average correlatiom coefficient of temperature variations falls to 0.5 at middle and high latitudes and 0.33 at low latitude
Who would believe that it all depends on a correlation coefficient of…0.5?
(many thanks to Sancho and the guys at Climate Monitor for inspiring this blog)
Just like with the drowning polar bears that weren’t in 2008, the Daily Mail is now the source of another idiotic “it’s climate change!” story. Ver shortly, reports of the town of Ilulissat having seen the sun two days earlier than usual after the darkness of winter, have been presented as the result of “melting ice caps” that “have lowered the horizon allowing the sun to shine through earlier“.
Of course this was unsubstantiated speculation, starting from the simple fact that in the direction of the rising sun (due South, in these days in Ilulissat) there is no ice to melt. There have been a few theories on the “inexplicable” phenomenon. The simplest one by far, is the Novaya Zemlja Effect (h/t Fabrizio). Perhaps, it should go without saying:
The Novaya Zemlya effect will give the impression that the sun is rising earlier than it actually should…
Livescience.com manages to make a good article out of it. The best one can do about this sad story is to use to check which AGWers have been victim of scichosis (h/t TomFP), “whose sufferers use perverse extension of uncontroversial science to frighten themselves and others witless“:
1- Thomas Posch, of the Institute for Astronomy of the University of Vienna (proving there’s always a scientist available to wildly speculate to a reporter about anything)
4- An untold number of bloggers I cannot be bothered to link to
5- That’s it
Very few people have fallen for the latest Daily Mail pearl. Maybe it’s because of Climategate, maybe catastrophism is going out of fashion (see Guardian’s “false claim” story, a journalistic indictment of the AAAS). Hope at last!
Continuing in my investigation of how “unfair” the situation is regarding Arctic sea ice and its forever-negative anomaly (forever-negative since it is calculated against a reference is pretty much the most sea ice the Arctic will ever going to see), some curious results about where the 1.1 million square kilometers are missing from.
The edges, that is.
As of Jan 16, Cryosphere Today reports 1.131M sq km of missing Northern Hemisphere sea ice area.
If you go into more details, the situation is:
Total is 1.05M sq km already. If you then look at all the other areas, you will find them pretty much all
In other words, there is no way that those places could contribute a positive anomaly that would balance out the negative ones listed abov. The only Arctic place that could contribute anything positive to the anomaly is actually the Barents Sea (where it is currently zero).
And where are all these non-full negative-anomaly areas placed? Why, they are all at the edges of the Arctic ocean.
This strongly indicates it’s not a generalized Arctic warming that is behind the “missing Arctic sea ice area”/negative anomaly, but something connected to sea currents.In fact, the Hudson Bay situation shows this nicely: it’s not the actual Bay that is missing most of the ice, it’s the Hudson Strait linking the Bay to the (negative-anomaly) Baffin/Newfoundland area.
Yes it’s another old New York Times article, this time from July 12, 1953. Stories of unusual weather, retreating ice caps, extreme events (at the time it was tornadoes). Yada yada yada.
Couple of interesting details. Journalist Leonard Engel provides a list of past attributions to human activities:
Unusual weather inevitably stirs up speculation as to the cause, in part, no doubt, because we like to talk about the weather anyway. And prominent event coincident with the exceptional weather is apt to be blamed. Heavy rains during World War I were popularly attributed to artillery bombardments in France. During the Twenties and Thirties it was fashionably to lay abnormal weather (along with other odd occurrences) to changes in the sunspot cycle. Today the popular villains of freak weather are atom-bomb tests and the activities of rainmakers.
Engel mentions also greenhouse gases and in particular the concentration of CO2
In 1850 the air contained somewhat less than thirty parts of carbon dioxide per 1,000 parts of air. In the hundred years since, industrialized, urbanized man has poured unprecedented quantities of carbon dioxide out of home and factory chimneys […] As a result, there are now thirty-three parts of the gas per 1,000 in the atmosphere instead of thirty.
Assuming Engel was just victim of some conversion mistake, and he meant 330ppm, it is curious to note that the figure is somewhat off Keeling’s original 1955 value of 310ppm.
Very quickly, a couple of notes on something that keeps bothering me…Arctic sea ice is the darling of AGW catastrophists, obviously not because its extension getting away from the 1979 maximum has been the most consistent “warming signal” (sorry, hurricanes!). But the geography of the Arctic makes it very difficult to beat the maximum.
For example looking at yesterday’s figures from Cryosphere Today (visual estimates) we have the Kara Sea, the East Siberian Sea and the Laptev Basin and the Arctic Basin pretty much at 100% or slightly lower of maximum-ever sea ice. Only thing, there is no way they can get ABOVE that 100% line, simply because they are already 100% covered by sea ice.
Greenland sea ice runs at -0.05 million square kilometers (84% of its possible maximum, but it usually peaks later in the season). Similar the situation for the Chukchi Sea, the St Lawrence area and the Barents Sea.
So we’re down to where the sea ice actually is missing: Baffin (it’s half of what it should be, but what is should be is “completely covered by sea ice), Hudson Bay (almost the same), Okhotsk (there is 0.1 m sq km missing, despite the ongoing drama, and again the expected value seems to be “completely covered”).
It is obviously very difficult for anybody to be above the zero-meter line if the zero-meter line is defined as the top of Mount Everest. Likewise, we should never expect news of a “healthy” Arctic sea ice extent unless it gets chocked-full of ice: in other words, we should never expect news of a “healthy” Arctic sea ice, really…
Therefore, the use of Arctic sea ice extent to investigate the effects of climate change, and in particular the use of the late-1970s as reference period, is bound to be limited.
In their weekly “Science in the News” e-mail, the folks at American Scientist have just managed to include a series of good news about the climate, without much of an acknowledgment. So here they are:
I do expect AS to come out against current mainstream AGW theory sooner rather than later (sooner than the hopeless critical-thinking-free Scientific American, at least). One little chip at a time, even the strongest wall will come down.
Not that they really wanted to be so generous, mind you…but in the printed (IHT) version of this long article about the Keelings and CO2 concentration measurements, somebody at the NYT decided to include this graph:
And so millions around the world will be able to see that temperatures have gone up and down in the past 400,000 years, with a characteristic shape (sharp increase with an even more marked peak, slow decline, then sharp increase again) that is currently being replicated (and the top temperatures of the past haven’t been reached yet). The usual reply is that in the past it’s been changes in the Earth’s orbit what drove the temperature changes: and yet, even if CO2 is the “culprit” this time there is evidently something in the Earth’s climate that:
In the medium and long run, humanity should be preparing for a cooler world. Preparation means of course adaptation, the one thing nobody wants to do.
If a rich man has two chickens, and a poor man none, both people are well-fed on average whilst one of them dies of starvation. Likewise for Global Warming.
This is a paradox strictly linked to the idea of working with temperature anomalies on a planetary scale. Imagine in fact if we had a Polar station with an anomaly of +15C, with average temperature going from -60C to -55C; and a Temperate-zone station with an anomaly of -5C, with average temperature going from +10C to +5C.
In those circumstances, the planetary temperature anomaly would go +10C, even if everybody would experience it quite cold. Worse: if the temperate areas had anomalies around zero, the planetary temperature anomaly would shoot to +15C, a giant number with no practical consequence whatsoever: because if the temperatures go up mostly where it’s very very cold, nobody anywhere sees any of the fabled “warming” effects linked to temperature increases.
And in case you wonder, that’s exactly what is happening, according to GISS, on planet Earth.
The “AGW is logically impossible” list (aka Global Warming Miracles) has suddenly jumped to 52 items, doubling in size in a little less than three weeks. As commented at the Italian version of the page, I am now only 43 items away from putting a poster at the Castle Church in Wittenberg, Germany.
Or perhaps I should find out where the bulletin boards are, at the University of East Anglia…
Is there anything peculiar happening in the Arctic in our time? Unfortunately, satellite-based sea-ice measurements only start from 1979, i.e. have just barely crossed the magic 30-year line that we’re told separates “weather” from “climate” (in other words, we have just been able to say that, according to mainstream climatology, the ice in 1995 was on the decrease).
A different way to look at the issue is to source information from relatively old books and newspaper articles. And there are good indications that their analysis will show quite large changes in the Arctic sea-ice extension across the centuries.
As it happens, I was sent yesterday the link to a very interesting 1818 compendium edition of mid-1770’s North-Pole-related thoughts and reports by Danies Barrington FRS of “young Mozart” fame: “The Possibility of Approaching the North Pole Asserted“.
Barrington goes at great length both in collecting as much evidence as possible from seamen claiming to have been further North than would have been expected; and in examining such evidence with a healthy dose of skepticism. His conclusions: several ships have been beyond 82N, and many of them have reported clear water to the North (see page 61). And yes, uncertainties were put in plain sight: finding a way to reach Asia without going around the tip of South America was considered very serious business, and even a strong advocate for Polar exploration like Barrington didn’t try to hide what he might have found uncomfortable. A quarter of a millennium later, we can be fairly certain ships at Barrington’s time were regularly reaching 81N.
Fast forward to 1858 and a “letter” on the New York Times by a Col. Peter Force, actually the text of a lecture at the New-York Historical Society on July 1st of that year. Col. Force appears extremely skeptical of any claim about the very existence of a Northwest Passage, going as far as to use that old saying, “if it were there we would have discovered it by now”. And if you look at the details reported, the 82N of 80 years earlier was then almost an unreachable goal, as there is plenty of mentions of sea ice going as low as 69N.
Arctic sea ice was therefore extending much further to the South in 1858 than in 1775. But were the CO2 emissions in 1775 higher than in 1858? I do not think so.
