    Climategate: CRU Was But the Tip of the Iceberg
    By Marc Sheppard
    Not surprisingly, the blatant corruption exposed at Britain’s premiere climate institute was not contained within the nation’s borders. Just months after the Climategate scandal broke, a new study has uncovered compelling evidence that our government’s principal climate centers have also been manipulating worldwide temperature data in order to fraudulently advance the global warming political agenda.

    Not only does the preliminary report [PDF] indict a broader network of conspirators, but it also challenges the very mechanism by which global temperatures are measured, published, and historically ranked.

    Last Thursday, Certified Consulting Meteorologist Joseph D’Aleo and computer expert E. Michael Smith appeared together on KUSI TV [Video] to discuss the Climategate -- American Style scandal they had discovered. This time out, the alleged perpetrators are the National Oceanic and Atmospheric Administration (NOAA) and the NASA Goddard Institute for Space Studies (GISS).

    NOAA stands accused by the two researchers of strategically deleting cherry-picked, cooler-reporting weather observation stations from the temperature data it provides the world through its National Climatic Data Center (NCDC). D’Aleo explained to show host and Weather Channel founder John Coleman that while the Hadley Center in the U.K. has been the subject of recent scrutiny, “[w]e think NOAA is complicit, if not the real ground zero for the issue.”

    And their primary accomplices are the scientists at GISS, who put the altered data through an even more biased regimen of alterations, including intentionally replacing the dropped NOAA readings with those of stations located in much warmer locales.

    As you’ll soon see, the ultimate effects of these statistical transgressions on the reports which influence climate alarm and subsequently world energy policy are nothing short of staggering.

    NOAA – Data In / Garbage Out

    Although satellite temperature measurements have been available since 1978, most global temperature analyses still rely on data captured from land-based thermometers, scattered more or less about the planet. It is that data which NOAA receives and disseminates – although not before performing some sleight-of-hand on it.

    Smith has done much of the heavy lifting involved in analyzing the NOAA/GISS data and software, and he chronicles his often frustrating experiences at his fascinating website. There, detail-seekers will find plenty to satisfy, divided into easily-navigated sections -- some designed specifically for us “geeks,” but most readily approachable to readers of all technical strata.

    Perhaps the key point discovered by Smith was that by 1990, NOAA had deleted from its datasets all but 1,500 of the 6,000 thermometers in service around the globe.

    Now, 75% represents quite a drop in sampling population, particularly considering that these stations provide the readings used to compile both the Global Historical Climatology Network (GHCN) and United States Historical Climatology Network (USHCN) datasets. These are the same datasets, incidentally, which serve as primary sources of temperature data not only for climate researchers and universities worldwide, but also for the many international agencies using the data to create analytical temperature anomaly maps and charts.

    Yet as disturbing as the number of dropped stations was, it is the nature of NOAA’s “selection bias” that Smith found infinitely more troubling.

    It seems that stations placed in historically cooler, rural areas of higher latitude and elevation were scrapped from the data series in favor of more urban locales at lower latitudes and elevations. Consequently, post-1990 readings have been biased to the warm side not only by selective geographic location, but also by the anthropogenic heating influence of a phenomenon known as the Urban Heat Island Effect (UHI).

    For example, Canada’s reporting stations dropped from 496 in 1989 to 44 in 1991, with the percentage of stations at lower elevations tripling while the numbers of those at higher elevations dropped to one. That’s right: As Smith wrote in his blog, they left “one thermometer for everything north of LAT 65.” And that one resides in a place called Eureka, which has been described as “The Garden Spot of the Arctic” due to its unusually moderate summers.

    Smith also discovered that in California, only four stations remain – one in San Francisco and three in Southern L.A. near the beach – and he rightly observed that

    It is certainly impossible to compare it with the past record that had thermometers in the snowy mountains. So we can have no idea if California is warming or cooling by looking at the USHCN data set or the GHCN data set.

    That’s because the baseline temperatures to which current readings are compared were a true averaging of both warmer and cooler locations. And comparing these historic true averages to contemporary false averages – which have had the lower end of their numbers intentionally stripped out – will always yield a warming trend, even when temperatures have actually dropped.

    Overall, U.S. online stations have dropped from a peak of 1,850 in 1963 to a low of 136 as of 2007. In his blog, Smith wittily observed that “the Thermometer Langoliers have eaten 9/10 of the thermometers in the USA[,] including all the cold ones in California.” But he was deadly serious after comparing current to previous versions of USHCN data and discovering that this “selection bias” creates a +0.6°C warming in U.S. temperature history.

    And no wonder -- imagine the accuracy of campaign tracking polls were Gallup to include only the replies of Democrats in their statistics. But it gets worse.

    Prior to publication, NOAA effects a number of “adjustments” to the cherry-picked stations’ data, supposedly to eliminate flagrant outliers, adjust for time of day heat variance, and “homogenize” stations with their neighbors in order to compensate for discontinuities. This last one, they state, is accomplished by essentially adjusting each to jive closely with the mean of its five closest “neighbors.” But given the plummeting number of stations, and the likely disregard for the latitude, elevation, or UHI of such neighbors, it’s no surprise that such “homogenizing” seems to always result in warmer readings.

    The chart below is from Willis Eschenbach’s WUWT essay, “The smoking gun at Darwin Zero,” and it plots GHCN Raw versus homogeneity-adjusted temperature data at Darwin International Airport in Australia. The “adjustments” actually reversed the 20th-century trend from temperatures falling at 0.7°C per century to temperatures rising at 1.2°C per century. Eschenbach isolated a single station and found that it was adjusted to the positive by 6.0°C per century, and with no apparent reason, as all five stations at the airport more or less aligned for each period. His conclusion was that he had uncovered “indisputable evidence that the ‘homogenized’ data has been changed to fit someone’s preconceptions about whether the earth is warming.”


    WUWT’s editor, Anthony Watts, has calculated the overall U.S. homogeneity bias to be 0.5°F to the positive, which alone accounts for almost one half of the 1.2°F warming over the last century. Add Smith’s selection bias to the mix and poof – actual warming completely disappears!

    Yet believe it or not, the manipulation does not stop there.

    GISS – Garbage In / Globaloney Out

    The scientists at NASA’s GISS are widely considered to be the world’s leading researchers into atmospheric and climate changes. And their Surface Temperature (GISTemp) analysis system is undoubtedly the premiere source for global surface temperature anomaly reports.

    In creating its widely disseminated maps and charts, the program merges station readings collected from the Scientific Committee on Antarctic Research (SCAR) with GHCN and USHCN data from NOAA.

    It then puts the merged data through a few “adjustments” of its own.

    First, it further “homogenizes” stations, supposedly adjusting for UHI by (according to NASA) changing “the long term trend of any non-rural station to match the long term trend of their rural neighbors, while retaining the short term monthly and annual variations.” Of course, the reduced number of stations will have the same effect on GISS’s UHI correction as it did on NOAA’s discontinuity homogenization – the creation of artificial warming.

    Furthermore, in his communications with me, Smith cited boatloads of problems and errors he found in the Fortran code written to accomplish this task, ranging from hot airport stations being mismarked as “rural” to the “correction” having the wrong sign (+/-) and therefore increasing when it meant to decrease or vice-versa.

    And according to NASA, “If no such neighbors exist or the overlap of the rural combination and the non-rural record is less than 20 years, the station is completely dropped; if the rural records are shorter, part of the non-rural record is dropped.”

    However, Smith points out that a dropped record may be “from a location that has existed for 100 years.” For instance, if an aging piece of equipment gets swapped out, thereby changing its identification number, the time horizon reinitializes to zero years. Even having a large enough temporal gap (e.g., during a world war) might cause the data to “just get tossed out.”

    But the real chicanery begins in the next phase, wherein the planet is flattened and stretched onto an 8,000-box grid, into which the time series are converted to a series of anomalies (degree variances from the baseline). Now, you might wonder just how one manages to fill 8,000 boxes using 1,500 stations.

    Here’s NASA’s solution:

    For each grid box, the stations within that grid box and also any station within 1200km of the center of that box are combined using the reference station method.

    Even on paper, the design flaws inherent in such a process should be glaringly obvious.

    So it’s no surprise that Smith found many examples of problems surfacing in actual practice. He offered me Hawaii for starters. It seems that all of the Aloha State’s surviving stations reside in major airports. Nonetheless, this unrepresentative hot data is what’s used to “infill” the surrounding “empty” Grid Boxes up to 1200 km out to sea. So in effect, you have “jet airport tarmacs ‘standing in’ for temperature over water 1200 km closer to the North Pole.”

    An isolated problem? Hardly, reports Smith.

    From KUSI’s Global Warming: The Other Side:

    “There’s a wonderful baseline for Bolivia -- a very high mountainous country -- right up until 1990 when the data ends. And if you look on the [GISS] November 2009 anomaly map, you’ll see a very red rosy hot Bolivia [boxed in blue]. But how do you get a hot Bolivia when you haven’t measured the temperature for 20 years?”


    Of course, you already know the answer: GISS simply fills in the missing numbers – originally cool, as Bolivia contains proportionately more land above 10,000 feet than any other country in the world – with hot ones available in neighboring stations on a beach in Peru or somewhere in the Amazon jungle.

    Remember that single station north of 65° latitude which they located in a warm section of northern Canada? Joe D’Aleo explained its purpose: “To estimate temperatures in the Northwest Territory [boxed in green above], they either have to rely on that location or look further south.”

    Pretty slick, huh?

    And those are but a few examples. In fact, throughout the entire grid, cooler station data are dropped and “filled in” by temperatures extrapolated from warmer stations in a manner obviously designed to overestimate warming...

    ...And convince you that it’s your fault.

    Government and Intergovernmental Agencies -- Globaloney In / Green Gospel Out

    Smith attributes up to 3°F (more in some places) of added “warming trend” between NOAA’s data adjustment and GIStemp processing.

    That’s over twice last century’s reported warming.

    And yet, not only are NOAA’s bogus data accepted as green gospel, but so are its equally bogus hysterical claims, like this one from the 2006 annual State of the Climate in 2005 [PDF]: “Globally averaged mean annual air temperature in 2005 slightly exceeded the previous record heat of 1998, making 2005 the warmest year on record.”

    And as D’Aleo points out in the preliminary report, the recent NOAA proclamation that June 2009 was the second-warmest June in 130 years will go down in the history books, despite multiple satellite assessments ranking it as the 15th-coldest in 31 years.

    Even when our own National Weather Service (NWS) makes its frequent announcements that a certain month or year was the hottest ever, or that five of the warmest years on record occurred last decade, they’re basing such hyperbole entirely on NOAA’s warm-biased data.

    And how can anyone possibly read GISS chief James Hansen’s Sunday claim that 2009 was tied with 2007 for second-warmest year overall, and the Southern Hemisphere’s absolute warmest in 130 years of global instrumental temperature records, without laughing hysterically? It's especially laughable when one considers that NOAA had just released a statement claiming that very same year (2009) to be tied with 2006 for the fifth-warmest year on record.

    So how do alarmists reconcile one government center reporting 2009 as tied for second while another had it tied for fifth? If you’re WaPo’s Andrew Freedman, you simply chalk it up to “different data analysis methods” before adjudicating both NASA and NOAA innocent of any impropriety based solely on their pointless assertions that they didn’t do it.

    Earth to Andrew: “Different data analysis methods”? Try replacing “analysis” with “manipulation,” and ye shall find enlightenment. More importantly, does the explicit fact that since the drastically divergent results of both “methods” can’t be right, both are immediately suspect somehow elude you?

    But by far the most significant impact of this data fraud is that it ultimately bubbles up to the pages of the climate alarmists’ bible: The United Nations Intergovernmental Panel on Climate Change Assessment Report.

    And wrong data begets wrong reports, which – particularly in this case – begets dreadfully wrong policy.

    It’s High Time We Investigated the Investigators

    The final report will be made public shortly, and it will be available at the websites of both report-supporter Science and Public Policy Institute and Joe D’Aleo’s own ICECAP. As they’ve both been tremendously helpful over the past few days, I’ll trust in the opinions I’ve received from the report’s architects to sum up.

    This from the meteorologist:

    The biggest gaps and greatest uncertainties are in high latitude areas where the data centers say they 'find' the greatest warming (and thus which contribute the most to their global anomalies). Add to that no adjustment for urban growth and land use changes (even as the world's population increased from 1.5 to 6.7 billion people) [in the NOAA data] and questionable methodology for computing the historical record that very often cools off the early record and you have surface based data sets so seriously flawed, they can no longer be trusted for climate trend or model forecast assessment or decision making by the administration, congress or the EPA.

    Roger Pielke Sr. has suggested: “...that we move forward with an inclusive assessment of the surface temperature record of CRU, GISS and NCDC. We need to focus on the science issues. This necessarily should involve all research investigators who are working on this topic, with formal assessments chaired and paneled by mutually agreed to climate scientists who do not have a vested interest in the outcome of the evaluations.” I endorse that suggestion.

    Certainly, all rational thinkers agree. Perhaps even the mainstream media, most of whom have hitherto mistakenly dismissed Climategate as a uniquely British problem, will now wake up and demand such an investigation.

    And this from the computer expert:

    That the bias exists is not denied. That the data are too sparse and with too many holes over time in not denied. Temperature series programs, like NASA GISS GIStemp try, but fail, to fix the holes and the bias. What is claimed is that "the anomaly will fix it." But it cannot. Comparison of a cold baseline set to a hot present set must create a biased anomaly. It is simply overwhelmed by the task of taking out that much bias. And yet there is more. A whole zoo of adjustments are made to the data. These might be valid in some cases, but the end result is to put in a warming trend of up to several degrees. We are supposed to panic over a 1/10 degree change of "anomaly" but accept 3 degrees of "adjustment" with no worries at all. To accept that GISTemp is "a perfect filter". That is, simply, "nuts". It was a good enough answer at Bastogne, and applies here too.

    Smith, who had a family member attached to the 101st Airborne at the time, refers to the famous line from the 101st commander, U.S. Army General Anthony Clement McAuliffe, who replied to a German ultimatum to surrender the December, 1944 Battle of Bastogne, Belgium with a single word: “Nuts.”

    And that’s exactly what we’d be were we to surrender our freedoms, our economic growth, and even our simplest comforts to duplicitous zealots before checking and double-checking the work of the prophets predicting our doom should we refuse.

    And another one from the times today!!

    http://www.timesonline.co.uk/tol/news/environment/article7000063.ece?token=null&offset=0&page=1
    UN wrongly linked global warming to natural disasters
    Jonathan Leake, Science and Environment Editor



    THE United Nations climate science panel faces new controversy for wrongly linking global warming to an increase in the number and severity of natural disasters such as hurricanes and floods.

    It based the claims on an unpublished report that had not been subjected to routine scientific scrutiny — and ignored warnings from scientific advisers that the evidence supporting the link too weak. The report's own authors later withdrew the claim because they felt the evidence was not strong enough.

    The claim by the Intergovernmental Panel on Climate Change (IPCC), that global warming is already affecting the severity and frequency of global disasters, has since become embedded in political and public debate. It was central to discussions at last month's Copenhagen climate summit, including a demand by developing countries for compensation of $100 billion (£62 billion) from the rich nations blamed for creating the most emissions.

    Ed Miliband, the energy and climate change minister, has suggested British and overseas floods — such as those in Bangladesh in 2007 — could be linked to global warming. Barack Obama, the US president, said last autumn: "More powerful storms and floods threaten every continent."
    Background

    Last month Gordon Brown, the prime minister, told the Commons that the financial agreement at Copenhagen "must address the great injustice that . . . those hit first and hardest by climate change are those that have done least harm".

    The latest criticism of the IPCC comes a week after reports in The Sunday Times forced it to retract claims in its benchmark 2007 report that the Himalayan glaciers would be largely melted by 2035. It turned out that the bogus claim had been lifted from a news report published in 1999 by New Scientist magazine.

    The new controversy also goes back to the IPCC's 2007 report in which a separate section warned that the world had "suffered rapidly rising costs due to extreme weather-related events since the 1970s".

    It suggested a part of this increase was due to global warming and cited the unpublished report, saying: "One study has found that while the dominant signal remains that of the significant increases in the values of exposure at risk, once losses are normalised for exposure, there still remains an underlying rising trend."

    The Sunday Times has since found that the scientific paper on which the IPCC based its claim had not been peer reviewed, nor published, at the time the climate body issued its report.

    When the paper was eventually published, in 2008, it had a new caveat. It said: "We find insufficient evidence to claim a statistical relationship between global temperature increase and catastrophe losses."

    Despite this change the IPCC did not issue a clarification ahead of the Copenhagen climate summit last month. It has also emerged that at least two scientific reviewers who checked drafts of the IPCC report urged greater caution in proposing a link between climate change and disaster impacts — but were ignored.

    The claim will now be re-examined and could be withdrawn. Professor Jean-Pascal van Ypersele, a climatologist at the Universite Catholique de Louvain in Belgium, who is vice-chair of the IPCC, said: "We are reassessing the evidence and will publish a report on natural disasters and extreme weather with the latest findings. Despite recent events the IPCC process is still very rigorous and scientific."


    The academic paper at the centre of the latest questions was written in 2006 by Robert Muir-Wood, head of research at Risk Management Solutions, a London consultancy, who later became a contributing author to the section of the IPCC's 2007 report dealing with climate change impacts. He is widely respected as an expert on disaster impacts.

    Muir-Wood wanted to find out if the 8% year-on-year increase in global losses caused by weather-related disasters since the 1960s was larger than could be explained by the impact of social changes like growth in population and infrastructure.

    Such an increase, coinciding with rising temperatures, might suggest that global warming was to blame. If proven this would be highly significant, both politically and scientifically, because it would confirm the many predictions that global warming will increase the frequency and severity of natural hazards.

    In the research Muir-Wood looked at a wide range of hazards, including tropical cyclones, thunder and hail storms, and wildfires as well as floods and hurricanes.
    Background

    He found from 1950 to 2005 there was no increase in the impact of disasters once growth was accounted for. For 1970-2005, however, he found a 2% annual increase which "corresponded with a period of rising global temperatures,"

    Muir-Wood was, however, careful to point out that almost all this increase could be accounted for by the exceptionally strong hurricane seasons in 2004 and 2005. There were also other more technical factors that could cause bias, such as exchange rates which meant that disasters hitting the US would appear to cost proportionately more in insurance payouts.

    Despite such caveats, the IPCC report used the study in its section on disasters and hazards, but cited only the 1970-2005 results.

    The IPCC report said: "Once the data were normalised, a small statistically significant trend was found for an increase in annual catastrophe loss since 1970 of 2% a year." It added: "Once losses are normalised for exposure, there still remains an underlying rising trend."

    Muir-Wood's paper was originally commissioned by Roger Pielke, professor of environmental studies at Colorado University, also an expert on disaster impacts, for a workshop on disaster losses in 2006. The researchers who attended that workshop published a statement agreeing that so far there was no evidence to link global warming with any increase in the severity or frequency of disasters. Pielke has also told the IPCC that citing one section of Muir-Wood's paper in preference to the rest of his work, and all the other peer-reviewed literature, was wrong.

    He said: "All the literature published before and since the IPCC report shows that rising disaster losses can be explained entirely by social change. People have looked hard for evidence that global warming plays a part but can't find it. Muir-Wood's study actually confirmed that."

    Mike Hulme, professor of climate change at the Tyndall Centre, which advises the UK government on global warming, said there was no real evidence that natural disasters were already being made worse by climate change. He said: “A proper analysis shows that these claims are usually superficial”

    Such warnings may prove uncomfortable for Miliband whose recent speeches have often linked climate change with disasters such as the floods that recently hit Bangladesh and Cumbria. Last month he said: “We must not let the sceptics pass off political opinion as scientific fact. Events in Cumbria give a foretaste of the kind of weather runaway climate change could bring. Abroad, the melting of the Himalayan glaciers that feed the great rivers of South Asia could put hundreds of millions of people at risk of drought. Our security is at stake.”

    Muir-Wood himself is more cautious. He said: "The idea that catastrophes are rising in cost partly because of climate change is completely misleading. "We could not tell if it was just an association or cause and effect. Also, our study included 2004 and 2005 which was when there were some major hurricanes. If you took those years away then the significance of climate change vanished."

    Some researchers have argued that it is unfair to attack the IPCC too strongly, pointing out that some errors are inevitable in a report as long and technical as the IPCC's round-up of climate science. "Part of the problem could simply be that expectations are too high," said one researcher. "We have been seen as a scientific gold standard and that's hard to live up to."

    Professor Christopher Field,director of the Department of Global Ecology at the Carnegie Institution in California, who is the new co-chairman of the IPCC working group overseeing the climate impacts report, said the 2007 report had been broadly accurate at the time it was written.

    He said: “The 2007 study should be seen as “a snapshot of what was known then. Science is progressive. If something turns out to be wrong we can fix it next time around.” However he confirmed he would be introducing rigorous new review procedures for future reports to ensure errors were kept to a minimum.

    Most of the original research on the GISTEMP scandal, including the Bolivian interpolation from Brazil and the Templehof airport fiddling is done by a blogger named Chiefio. I think that is Mr Smith.

    I have been researching it for some time....before I form a really hard opinion. I confess I cannot find any major faults with what Chiefio is saying so far. But I need to so some more research. Here is the blog itself.

    http://chiefio.wordpress.com/

    Here is his an explanation of the deconstruction of GISTEMP, this is the overview article you should start with.

    http://chiefio.wordpress.com/2009/11/09/gistemp-a-human-view/

    Basically he says high altitude and latitude data is being deliberately discarded for low altitude and low latitude temperature series over time and absent this data the world is provably hot.

    Nobody seems to have rebutted Chiefio since he really got in gear some time before Climategate in mid 2009.

    From the latter link.
    Since about 1990, there has been a reduction in thermometer counts globally. In the USA, the number has dropped from 1850 at peak (in the year 1968) to 136 now (in the year 2009). As you might guess, this has presented some “issues” for our thermal quilt. But do not fear, GIStemp will fill in what it needs, guessing as needed, stretching and fabricating until it has a result. In Japan, no thermometers now record above 300 meters. Japan has no mountains now. For California, where we once had thermometers in the mountain snow and in the far north near Oregon; there are now 4 surviving thermometers near the beach and in the warm south. But GIStemp is sure we can use them as a fine proxy for Mount Shasta with it’s glaciers and for the snows and ice of Yosemite winters.

    And there is a LOT of stuff on this blog. Form your own opinion please.

    GISTEMP has a weather station list here

    Each station has a numeric code. However Chiefio maintains that some substitution takes place within the dataset before processes are run.

    This interpolation process is explained vis a vis California in this post here

    The Irish selection of stations looks perfectly good....as long as real data is not discarded and something near Bordeaux is 'interpolated' against Shannon or Malin for some reason.

    Now to the stations that are actually used in Ireland .

    Some weather stations like Galway and Claremorris no longer exist.

    Click on http://data.giss.nasa.gov/cgi-bin/gistemp/findstation.py?lat=53.08&lon=-7.88&datatype=gistemp&data_set=1

    You will note that the stations used for the current GISTemp model series are a subset of all stations for purposes of global warming modelling , that list is everything within 500km of Birr. Note dates on right please.

    The stations from which data is currently extracted is "heavy on the airports" which is one of the serious accusations made against GISTemp.I will address that later in this post.

    Dublin Casement Belfast Aldergrove and Cork airports are used. So are Malin and Valentia and Belmullet and Rosslare was recently discarded but Johnstown Castle nearby was not introduced. The rest are ignored

    The pattern evident there is that ALL stations used for modelling are either coastal or located in an airport.

    No rural stations are used at all.....meaning inland but not airports , they have been DISCARDED.

    Chiefio explains his 'issues' with airports in this post here

    http://chiefio.wordpress.com/2009/08/23/gistemp-fixes-uhi-using-airports-as-rural/

    Do note Chiefios 'issues with CONCRETE, that is essential.


    I also have issues with the overall selection of inland stations USED to model Ireland ...none really with the coastal selection.

    But from now on you must start RUNNING the model to see if stations are substitued for stations on an actual model run ....and when and why...eg whether Casement becomes Orly or Shannon becomes Stansted.

    I have not run the model and am NOT SAYING IT HAPPENS .....but inevitably one must run the model and find out if data is beng substituted out during runs and the effect thereof.

    That is when it gets really complicated and proving anything would be a group effort.

    You do however know that an ideologically fascist green like Eamon Ryan will not fund your efforts or engage with you in any way and so you are on your own against official Ireland which has bought into Global warming and carbon taxes.

    Like the feckin x files, only for real :cool:

    'Reputable' is fast becoming a relative term regarding this issue.

    Off topic, I am beginning to wonder lately why the 61-90 average is still being used in most cases today regarded current monthly and yearly figures as a 'normal'. Even our own met eireann still use it to compare current values; surely it is about time it was upped to the 71-00 normal by now? Give another year, and we could be using the 81-10 average.

    Is there a reason as to why the 71-00 average is not being used Dan? as surely it would be a bit more relevent to modern readings? A 76-05 average would be even better!


  • Closed Accounts Posts: 4,279 ✭✭✭Su Campu


    The official reason is that the 61-90 range is the most "representative" of Irish climate, whatever that means? :rolleyes: Before the 60s there was warming, and the same after, but in the 60s, 70s and 80s, there was cooling followed by warming, which cancelled eachother out and gave a level baseline.

    That's the official reason anyway. I don't believe a word we're told anymore. See the real reason is that if we're in a warming period, then the averages will be also on the rise, so any subsequent warm years can't be quoted as being as much above average, therefore people might start to think the warming is slowing down.....:rolleyes: Eg, take the 71-00 averages. They will be a lot higher than the 61-90. Therefore if 2010 turns out to be a warm year, the anomaly won't look so drastic using the 71-00 averages, say only 0.4°C, compared to maybe 1.0°C using the 61-90 (they're just figures out of my head - not sure the actual figures would be). Therefore they lose ground on trying to promote the AGW lie.

    Scandalous

    The climate of a given region is generally taken as a 30 year period. It's just the way it is, I don't think there is any real reason for it other than keeping accurate statistical trends (and maybe to account for the 10-15 year latency of the oceans? Don't think so though.) . The next period will be 1991-2020. I wouldn't really bother reading any further into than that.

    I'm not sure you understand climate at all, even if Ireland cooled by 15 degrees in the 61-90 30 year period that wouldn't say anything about the Global Climate. Ireland, afterall, is just one localised area in a big sum. What matters is the Global Trend of entire planet as whole. Usually best measured via ocean imbalance. AFAIK different regions using different 30 year periods.:D

    That the entire global temperature change trend is considered so important, now that is a question that needs answering.

    Local variations can and do often cancel each other out, global variations can happen as well, who's to say they are caused by climate or by external sources such as solar activity.

    The current lower (than recent trend) solar activity could provide an answer in the next decade!

    As for trending data, it makes more sense to use a rolling period of say 30 years than to have fixed "windows" otherwise housebuilders in Ireland would look at sales in 2005-7 and decide it's a good time to build!

    Solar activity does not provide an answer for the last 4 decades of warming. And it looks increasingly unlikely that it will do so for the next decade either. Last year the sun was inactive and weaker than usual. Yet 2009 was the 2nd warmest year on record with much warmer temperatures recorded at night time. (Warming at night is not something you'd expect if the sun was the primary driver of warming.)

    You've mixed stuff up here. The 30 year period is just the way we define climate in a region. It's not how you measure or statistically analyse global temperature trends. No one ever said it was. It just purely convention, like the metric system we define climate in a region as the frequency of weather occurrences that occurred over a 30 year period.
    What you have suggested above is nearly always screened when analysing trends in a global climate efforts. One of the criticism in the US. NAS assessment of Mann's Hockey Stick was his failure to consult a statistician to apply a rigorous statistical analysis on the data presented.

    As climate is a largely statistical phenomenon it goes without saying that if they were making such basic errors it would be truly shocking. Although a quick look through the majority of the journals will tell you the opposite. Nearly every paper that is published outlines how the data was analysed and discusses the possible drawbacks to the approach they used - the drawbacks the authors themselves were aware of.

    Solar activity has been higher than average (over the the past few centuries of recorded data) during the past few decades, so imho it could still be a factor - time will tell.

    As for nighttime temperatures, I can't comment as I don't have the info.

    If I understand you correctly, the last "climate period" was from 1961-1990, a period that started by cooling which was followed by heating and ended up warmer than it started. This is the base line for future warming!! :confused:

    No, it's just a base line for describing the climate of a particular region. Nothing less, nothing more. Analysis of data or trends is done using various different techniques that may or may not incorporate such a set period.

    There's practically no correlation there. Solar activity could still be a factor but there's no evidence that really asserts or supports the claim that it is. Solar activity is always going to get higher and higher than average, just really slowly - Stars tend to do that.:)

    Millions of years time, way beyond human activity of any kind that is! ;)
    Sunspot activity on the other hand has been recorded and activity can be corelated* to climate changes in north western Europe, as to whether it can related to changes elsewhare... I don't have the data.

    Yeah, I know. Solar activity has definitely correlated well with some past climate changes: It doesn't always. C02, Milankovitch Cycles, etc are all the same : sometimes they affect climate other times it's something else. The problem is that the last 40 or more years does not correspond to what you'd expect from primary solar forcing. It corresponds better, alot better, with anthropogenic forcing.

    As I blame Durkin (not a scientist, thank God!) for the common misconception of this, I'm going to let him explain himself.(An old video but worth it:))
    It goes without saying that you shouldn't trust either Durkin or Mr Gore. Though, I would have to give Gore more credit for accuracy:).

    400 years of approximate corellation as opposed to 40 years of non-correlation, which do you prefer?


  • Registered Users Posts: 26,578 ✭✭✭✭Turtwig


    400 years of approximate corellation as opposed to 40 years of non-correlation, which do you prefer?

    Neither, unless you've got plausible causation. You've also got millions of years of C02 correlation, millions of years of Orbital Shifts, thousands of years of impact correlations, ice movements, continental drifts etc etc.
    The climate has being influenced by many things, that was the challenged climatologists faced when assessing whether manmade GHGs were really that influential. Afterall, they're such a minute amount compare natural processes. Amount isn't everything though; a tiny cyanide pill will kill you.

    (Interesting article on the history of the development of the theory available here if you're interested.)

    Beryllium-10 is an isotope that is a proxy for the sun’s activity. Be10 is produced in the atmosphere by cosmic ray collisions with atoms of oxygen and nitrogen. Beryllium 10 concentrations are linked to cosmic ray intensity which can be a proxy for solar strength.

    One way to capture earth’s record of that proxy data is to drill deep ice cores. Greenland, due to having a large and relatively stable deep ice sheet is often the target for drilling ice cores.

    Isotopic analysis of the ice in the core can be linked to temperature and global sea level variations. Analysis of the air contained in bubbles in the ice can reveal the palaeocomposition of the atmosphere, in particular CO2 variations. Volcanic eruptions leave identifiable ash layers.



    Plotted up and annotated, the Dye 3 B10 data shows the strong relationship between solar activity and climate. Instead of wading through hundreds of papers for evidence of the Sun’s influence on terrestrial climate, all you have to do is look at this graph.

    be10-climate.png?w=510&h=272

    All the major climate minima are evident in the Be10 record, and the cold period at the end of the 19th century. This graph alone demonstrates that the warming of the 20th century was solar-driven.

    The end of the Little Ice Age corresponded with a dramatic decrease in the rate of production of Be10, due to fewer galactic cosmic rays getting into the inner planets of the solar system. Fewer galactic cosmic rays got into the inner planets because the solar wind got stronger. The solar wind got stronger because the Sun’s magnetic field got stronger, as measured by the aa Index from 1868.

    Thus the recent fall of aa Index and Ap Index to lows never seen before in living memory is of considerable interest. This reminds me of a line out of Aliens: “Stay frosty people!” Well, we won’t have any choice – it will get frosty.

    ap_index_2008-520.png?w=520&h=289&h=289 The Ap magentic index to the end of 2008



    so to cap in my own words, THE MORE COSMIC RAYS YOU HAVE ,THE MORE B 10 THERE IS,AS HIGHLIGHTED AT THE TIME OF THE 3 SOLAR MINIMUMS ON CHART,NOW THATS INTERESTING.

    Timothy Patterson is professor and director of the Ottawa-Carleton Geoscience Centre, Department of Earth Sciences, Carleton University

    Appearing before the Commons Committee on Environment and Sustainable Development , Carleton University paleoclimatologist Professor Tim Patterson testified, "There is no meaningful correlation between CO2 levels and Earth's temperature over this [geologic] time frame. In fact, when CO2 levels were over ten times higher than they are now, about 450 million years ago, the planet was in the depths of the absolute coldest period in the last half billion years." Patterson asked the committee, "On the basis of this evidence, how could anyone still believe that the recent relatively small increase in CO2 levels would be the major cause of the past century's modest warming?"


    Patterson concluded his testimony by explaining what his research and "hundreds of other studies" reveal: on all time scales, there is very good correlation between Earth's temperature and natural celestial phenomena such changes in the brightness of the Sun.




    This shows one of the highest-quality climate records available anywhere today and in it we see obvious confirmation that natural climate change can be dramatic.



    My research team began to collect and analyze core samples from the bottom of deep Western Canadian fjords. The regions in which we chose to conduct our research, Effingham Inlet on the West Coast of Vancouver Island, and in 2001, sounds in the Belize-Seymour Inlet complex on the mainland coast of British Columbia, were perfect for this sort of work. The topography of these fjords is such that they contain deep basins that are subject to little water transfer from the open ocean and so water near the bottom is relatively stagnant and very low in oxygen content. As a consequence, the floors of these basins are mostly lifeless and sediment layers build up year after year, undisturbed over millennia.


    Using various coring technologies, we have been able to collect more than 5,000 years' worth of mud in these basins, with the oldest layers coming from a depth of about 11 metres below the fjord floor. Clearly visible in our mud cores are annual changes that record the different seasons: corresponding to the cool, rainy winter seasons, we see dark layers composed mostly of dirt washed into the fjord from the land; in the warm summer months we see abundant fossilized fish scales and diatoms (the most common form of phytoplankton, or single-celled ocean plants) that have fallen to the fjord floor from nutrient-rich surface waters. In years when warm summers dominated climate in the region, we clearly see far thicker layers of diatoms and fish scales than we do in cooler years. Ours is one of the highest-quality climate records available anywhere today and in it we see obvious confirmation that natural climate change can be dramatic. For example, in the middle of a 62-year slice of the record at about 4,400 years ago, there was a shift in climate in only a couple of seasons from warm, dry and sunny conditions to one that was mostly cold and rainy for several decades.


    Using computers to conduct what is referred to as a "time series analysis" on the colouration and thickness of the annual layers, we have discovered repeated cycles in marine productivity in this, a region larger than Europe. Specifically, we find a very strong and consistent 11-year cycle throughout the whole record in the sediments and diatom remains. This correlates closely to the well-known 11-year "Schwabe" sunspot cycle, during which the output of the sun varies by about 0.1%. Sunspots, violent storms on the surface of the sun, have the effect of increasing solar output, so, by counting the spots visible on the surface of our star, we have an indirect measure of its varying brightness. Such records have been kept for many centuries and match very well with the changes in marine productivity we are observing.


    In the sediment, diatom and fish-scale records, we also see longer period cycles, all correlating closely with other well-known regular solar variations. In particular, we see marine productivity cycles that match well with the sun's 75-90-year "Gleissberg Cycle," the 200-500-year "Suess Cycle" and the 1,100-1,500-year "Bond Cycle." The strength of these cycles is seen to vary over time, fading in and out over the millennia. The variation in the sun's brightness over these longer cycles may be many times greater in magnitude than that measured over the short Schwabe cycle and so are seen to impact marine productivity even more significantly.


    Our finding of a direct correlation between variations in the brightness of the sun and earthly climate indicators (called "proxies") is not unique. Hundreds of other studies, using proxies from tree rings in Russia's Kola Peninsula to water levels of the Nile, show exactly the same thing: The sun appears to drive climate change.

    So tis a great debate for all and sorry for repeating myself but
    ONLY TIME WILL TELL:)

    I'm not sure how the significance of what you've showed me has gone against anything I said. I agree that many past climate changes changes have been solar driven. I'm stating the scientific assertion that the current latter 20th century and 21st century warming isn't. All you've done is present evidence that shows that solar activity affects the climate. No climatologist said it doesn't, you've got to show why solar activity explains the last 40 years of climate change. Which, iirc, no one has been able to do yet. And there have been numerous attempts as well as ongoing ones. :)


    Also, I'm not the biggest fan of pseudoscience sites likehttp://wattsupwiththat.com/2009/03/17/beryllium-10-and-climate/.


    P.S 2009 was the 2nd warmest year on record. So frost in Ireland but not over the globe.:)

    Look take those sites as you will However, there was a problem.


    Despite this clear and repeated correlation, the measured variations in incoming solar energy were, on their own, not sufficient to cause the climate changes we have observed in our proxies. In addition, even though the sun is brighter now than at any time in the past 8,000 years, the increase in direct solar input is not calculated to be sufficient to cause the past century's modest warming on its own. There had to be an amplifier of some sort for the sun to be a primary driver of climate change.


    Indeed, that is precisely what has been discovered. In a series of groundbreaking scientific papers starting in 2002, Veizer, Shaviv, Carslaw, and most recently Svensmark et al., have collectively demonstrated that as the output of the sun varies, and with it, our star's protective solar wind, varying amounts of galactic cosmic rays from deep space are able to enter our solar system and penetrate the Earth's atmosphere. These cosmic rays enhance cloud formation which, overall, has a cooling effect on the planet. When the sun's energy output is greater, not only does the Earth warm slightly due to direct solar heating, but the stronger solar wind generated during these "high sun" periods blocks many of the cosmic rays from entering our atmosphere. Cloud cover decreases and the Earth warms still more.


    The opposite occurs when the sun is less bright. More cosmic rays are able to get through to Earth's atmosphere, more clouds form, and the planet cools more than would otherwise be the case due to direct solar effects alone. This is precisely what happened from the middle of the 17th century into the early 18th century, when the solar energy input to our atmosphere, as indicated by the number of sunspots, was at a minimum and the planet was stuck in the Little Ice Age. These new findings suggest that changes in the output of the sun caused the most recent climate change. By comparison, CO2 variations show little correlation with our planet's climate on long, medium and even short time scales but the data is there.

    We're all trying to make sense of it all and "scientists" too.

    Im just here waiting for the next big scandal,because alot in my opinion is not as it seems,for we live in a corrupt little world.

    THE END:D

    ^^ This paragraph does not accurately reflect the conclusions of the above authors. The above authors are genuine skeptics but they aren't saying what you and others have said here.
    On what record?
    NASA.

    Edit :Sh1t, sorry misinterpreted. Since modern instrumental records began.


  • Closed Accounts Posts: 2,693 ✭✭✭Redsunset


    Sure we're all skeptics.

    I only highlight this information as it comes so we can make our own mind up.

    Nothing is going to be settled now or the immediate future.

    I believe its all intergalactic related so maybe in 50 years we might all be singing from the same hymn sheet ,but until we all see the light its always going to be a tug of war.

    Believe what makes you happy IMO:)

    It was a false misrepresentation of the work done by scientists.


  • Closed Accounts Posts: 2,693 ✭✭✭Redsunset


    Oh yes here is your argument i assume,

    Two main conclusions result from our analysis of [Shaviv and Veizer, 2003]. The first is that the correlation of cosmic ray flux (CRF) and climate over the past 520 m.y. appears to not hold up under scrutiny. Even if we accept the questionable assumption that meteorite clusters give information on CRF variations, we find that the evidence for a link between CRF and climate amounts to little more than a similarity in the average periods of the CRF variations and a heavily smoothed temperature reconstruction. Phase agreement is poor. The authors applied several adjustments to the data to artificially enhance the correlation. We thus find that the existence of a correlation has not been convincingly demonstrated.

    Our second conclusion is independent of the first. Whether there is a link of CRF and temperature or not, the authors’ estimate of the effect of a CO2-doubling on climate is highly questionable. It is based on a simple and incomplete regression analysis which implicitly assumes that climate variations on time scales of millions of years, for different configurations of continents and ocean currents, for much higher CO2 levels than at present, and with unaccounted causes and contributing factors, can give direct quantitative information about the effect of rapid CO2 doubling from pre-industrial climate. The complexity and non-linearity of the climate system does not allow such a simple statistical derivation of climate sensitivity without a physical understanding of the key processes and feedbacks. We thus conclude that [Shaviv and Veizer, 2003] provide no cause for revising current estimates of climate sensitivity to carbon dioxide.

    Malty T says.

    "Last year the sun was inactive and weaker than usual. Yet 2009 was the 2nd warmest year on record with much warmer temperatures recorded at night time. (Warming at night is not something you'd expect if the sun was the primary driver of warming.)"

    Most of the claims from the alarmists over the lat 20 years must now be treated with extreme scepticism. We cannot know if 2009 was the second warmest because we don't know how the data have been manipulated and cherry picked.

    It looks increasingly like scientific fraud is at the heart of the AGW movement.

    >>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>

    Nope, I don't even need that.
    As a final qualification, we emphasize
    that our conclusion about the dominance
    of the CRF over climate variability is valid
    only on multimillion year time scales. At
    shorter time scales, other climatic factors
    may play an important role, but note that
    many authors (see previous references)
    suggest a decisive role for the celestial
    driver also on multi-millennial to less than
    annual time scales.

    A multi-million year timescale? Hmm..
