El Niño or ñot, the Pause lengthens again

Global temperature update: no warming for 18 years 4 months

By Christopher Monckton of Brenchley

Since December 1996 there has been no global warming at all (Fig. 1). This month’s RSS temperature – so far unaffected by the most persistent el Niño conditions of the present rather attenuated cycle – shows a new record length for the ever-Greater Pause: 18 years 4 months – and counting.

This result rather surprises me. I’d expected even a weak el Niño to have more effect that this, but it is always possible that the temperature increase that usually accompanies an el Niño will come through after a lag of four or five months. On the other hand, Roy Spencer, at his always-to-the-point blog (drroyspencer.com), says: “We are probably past the point of reaching a new peak temperature anomaly from the current El Niño, suggesting it was rather weak.” I shall defer to the expert, with pleasure. For if la Niña conditions begin to cool the oceans in time, there could be quite some lengthening of the Pause just in time for the Paris world-government summit in December.

Figure 1. The least-squares linear-regression trend on the RSS satellite monthly global mean surface temperature anomaly dataset shows no global warming for 18 years 4 months since December 1996.

The hiatus period of 18 years 4 months, or 220 months, is the farthest back one can go in the RSS satellite temperature record and still show a sub-zero trend.

Given that the Paris summit is approaching and most “world leaders” are not being told the truth about the Pause, it would be a great help if readers were to do their best to let their national negotiators and politicians know that unexciting reality continues to diverge ever more spectacularly from the bizarre “settled-science” predictions on which Thermageddon was built.

The divergence between the models’ predictions in 1990 (Fig. 2) and 2005 (Fig. 3), on the one hand, and the observed outturn, on the other, also continues to widen, and is now becoming a real embarrassment to the profiteers of doom – or would be, if the mainstream news media were actually to report the data rather than merely repeating the failed predictions of catastrophe.

The Technical Note has now been much expanded to take account of the fact that the oceans, according to the ARGO bathythermograph data, are scarcely warming.

Key facts about global temperature

Ø The RSS satellite dataset shows no global warming at all for 220 months from December 1996 to March 2014 – more than half the 435-month satellite record.

Ø The global warming trend since 1900 is equivalent to 0.8 Cº per century. This is well within natural variability and may not have much to do with us.

Ø Since 1950, when a human influence on global temperature first became theoretically possible, the global warming trend has been equivalent to below 1.2 Cº per century.

Ø The fastest warming rate lasting ten years or more since 1950 occurred over the 33 years from 1974 to 2006. It was equivalent to 2.0 Cº per century.

Ø In 1990, the IPCC’s mid-range prediction of near-term warming was equivalent to 2.8 Cº per century, higher by two-thirds than its current prediction of 1.7 Cº/century.

Ø The global warming trend since 1990, when the IPCC wrote its first report, is equivalent to below 1.4 Cº per century – half of what the IPCC had then predicted.

Ø Though the IPCC has cut its near-term warming prediction, it has not cut its high-end business as usual centennial warming prediction of 4.8 Cº warming to 2100.

Ø The IPCC’s predicted 4.8 Cº warming by 2100 is well over twice the greatest rate of warming lasting more than ten years that has been measured since 1950.

Ø The IPCC’s 4.8 Cº-by-2100 prediction is almost four times the observed real-world warming trend since we might in theory have begun influencing it in 1950.

Ø The oceans, according to the 3600+ ARGO bathythermograph buoys, are warming at a rate equivalent to just 0.02 Cº per decade, or 0.2 Cº per century.

Ø Recent extreme weather cannot be blamed on global warming, because there has not been any global warming to speak of. It is as simple as that.


 

Technical note

Our latest topical graph shows the least-squares linear-regression trend on the RSS satellite monthly global mean lower-troposphere dataset for as far back as it is possible to go and still find a zero trend. The start-date is not “cherry-picked” so as to coincide with the temperature spike caused by the 1998 el Niño. Instead, it is calculated so as to find the longest period with a zero trend.

The RSS dataset is arguably less unreliable than other datasets in that it shows the 1998 Great El Niño more clearly than all other datasets (though UAH runs it close). The Great el Niño, like its two predecessors in the past 300 years, caused widespread global coral bleaching, providing an independent verification that RSS is better able to capture such fluctuations without artificially filtering them out than other datasets. Besides, there is in practice little statistical difference between the RSS and other datasets over the 18-year period of the Great Pause.

Terrestrial temperatures are measured by thermometers. Thermometers correctly sited in rural areas away from manmade heat sources show warming rates below those that are published. The satellite datasets are based on reference measurements made by the most accurate thermometers available – platinum resistance thermometers, which provide an independent verification of the temperature measurements by checking via spaceward mirrors the known temperature of the cosmic background radiation, which is 1% of the freezing point of water, or just 2.73 degrees above absolute zero. It was by measuring minuscule variations in the cosmic background radiation that the NASA anisotropy probe determined the age of the Universe: 13.82 billion years.

The RSS graph (Fig. 1) is accurate. The data are lifted monthly straight from the RSS website. A computer algorithm reads them down from the text file, takes their mean and plots them automatically using an advanced routine that automatically adjusts the aspect ratio of the data window at both axes so as to show the data at maximum scale, for clarity.

The latest monthly data point is visually inspected to ensure that it has been correctly positioned. The light blue trend line plotted across the dark blue spline-curve that shows the actual data is determined by the method of least-squares linear regression, which calculates the y-intercept and slope of the line.

The IPCC and most other agencies use linear regression to determine global temperature trends. Professor Phil Jones of the University of East Anglia recommends it in one of the Climategate emails. The method is appropriate because global temperature records exhibit little auto-regression.

Dr Stephen Farish, Professor of Epidemiological Statistics at the University of Melbourne, kindly verified the reliability of the algorithm that determines the trend on the graph and the correlation coefficient, which is very low because, though the data are highly variable, the trend is flat.

RSS itself is now taking a serious interest in the length of the Great Pause. Dr Carl Mears, the senior research scientist at RSS, discusses it at remss.com/blog/recent-slowing-rise-global-temperatures.

Dr Mears’ results are summarized in Fig. T1:

clip_image008.png

Figure T1. Output of 33 IPCC models (turquoise) compared with measured RSS global temperature change (black), 1979-2014. The transient coolings caused by the volcanic eruptions of Chichón (1983) and Pinatubo (1991) are shown, as is the spike in warming caused by the great el Niño of 1998.

Dr Mears writes:

“The denialists like to assume that the cause for the model/observation discrepancy is some kind of problem with the fundamental model physics, and they pooh-pooh any other sort of explanation.  This leads them to conclude, very likely erroneously, that the long-term sensitivity of the climate is much less than is currently thought.”

Dr Mears concedes the growing discrepancy between the RSS data and the models, but he alleges “cherry-picking” of the start-date for the global-temperature graph:

“Recently, a number of articles in the mainstream press have pointed out that there appears to have been little or no change in globally averaged temperature over the last two decades.  Because of this, we are getting a lot of questions along the lines of ‘I saw this plot on a denialist web site.  Is this really your data?’  While some of these reports have ‘cherry-picked’ their end points to make their evidence seem even stronger, there is not much doubt that the rate of warming since the late 1990s is less than that predicted by most of the IPCC AR5 simulations of historical climate.  … The denialists really like to fit trends starting in 1997, so that the huge 1997-98 ENSO event is at the start of their time series, resulting in a linear fit with the smallest possible slope.”

In fact, the spike in temperatures caused by the Great el Niño of 1998 is largely offset in the linear-trend calculation by two factors: the not dissimilar spike of the 2010 el Niño, and the sheer length of the Great Pause itself.

Curiously, Dr Mears prefers the much-altered terrestrial datasets to the satellite datasets. However, over the entire length of the RSS and UAH series since 1979, the trends on the mean of the terrestrial datasets and on the mean of the satellite datasets are near-identical. Indeed, the UK Met Office uses the satellite record to calibrate its own terrestrial record.

The length of the Great Pause in global warming, significant though it now is, is of less importance than the ever-growing discrepancy between the temperature trends predicted by models and the far less exciting real-world temperature change that has been observed. It remains possible that el Nino-like conditions may prevail this year, reducing the length of the Great Pause. However, the discrepancy between prediction and observation continues to widen.

Sources of the IPCC projections in Figs. 2 and 3

IPCC’s First Assessment Report predicted that global temperature would rise by 1.0 [0.7, 1.5] Cº to 2025, equivalent to 2.8 [1.9, 4.2] Cº per century. The executive summary asked, “How much confidence do we have in our predictions?” IPCC pointed out some uncertainties (clouds, oceans, etc.), but concluded:

“Nevertheless, … we have substantial confidence that models can predict at least the broad-scale features of climate change. … There are similarities between results from the coupled models using simple representations of the ocean and those using more sophisticated descriptions, and our understanding of such differences as do occur gives us some confidence in the results.”

That “substantial confidence” was substantial over-confidence. For the rate of global warming since 1990 – the most important of the “broad-scale features of climate change” that the models were supposed to predict – is now below half what the IPCC had then predicted.

In 1990, the IPCC said this:

“Based on current models we predict:

“under the IPCC Business-as-Usual (Scenario A) emissions of greenhouse gases, a rate of increase of global mean temperature during the next century of about 0.3 Cº per decade (with an uncertainty range of 0.2 Cº to 0.5 Cº per decade), this is greater than that seen over the past 10,000 years. This will result in a likely increase in global mean temperature of about 1 Cº above the present value by 2025 and 3 Cº before the end of the next century. The rise will not be steady because of the influence of other factors” (p. xii).

Later, the IPCC said:

“The numbers given below are based on high-resolution models, scaled to be consistent with our best estimate of global mean warming of 1.8 Cº by 2030. For values consistent with other estimates of global temperature rise, the numbers below should be reduced by 30% for the low estimate or increased by 50% for the high estimate” (p. xxiv).

The orange region in Fig. 2 represents the IPCC’s less extreme medium-term Scenario-A estimate of near-term warming, i.e. 1.0 [0.7, 1.5] K by 2025, rather than its more extreme Scenario-A estimate, i.e. 1.8 [1.3, 3.7] K by 2030.

Some try to say the IPCC did not predict the straight-line global warming rate that is shown in Figs. 2-3. In fact, however, the IPCC’s predicted global warming over so short a term as the 25 years from 1990 to the present are little different from a straight line (Fig. T2).

clip_image010

Figure T2. Historical warming from 1850-1990, and predicted warming from 1990-2100 on the IPCC’s “business-as-usual” Scenario A (IPCC, 1990, p. xxii).

Because this difference between a straight line and the slight uptick in the warming rate the IPCC predicted over the period 1990-2025 is so small, one can look at it another way. To reach the 1 K central estimate of warming since 1990 by 2025, there would have to be twice as much warming in the next ten years as there was in the last 25 years. That is not likely.

Likewise, to reach 1.8 K by 2030, there would have to be four or five times as much warming in the next 15 years as there was in the last 25 years. That is still less likely.

But is the Pause perhaps caused by the fact that CO2 emissions have not been rising anything like as fast as the IPCC’s “business-as-usual” Scenario A prediction in 1990? No: CO2 emissions have risen rather above the Scenario-A prediction (Fig. T3).

clip_image012

Figure T3. CO2 emissions from fossil fuels, etc., in 2012, from Le Quéré et al. (2014), plotted against the chart of “man-made carbon dioxide emissions”, in billions of tonnes of carbon per year, from IPCC (1990).

Plainly, therefore, CO2 emissions since 1990 have proven to be closer to Scenario A than to any other case, because for all the talk about CO2 emissions reduction the fact is that the rate of expansion of fossil-fuel burning in China, India, Indonesia, Brazil, etc., far outstrips the paltry reductions we have achieved in the West to date.

True, methane concentration has not risen as predicted in 1990 (Fig. T4), for methane emissions, though largely uncontrolled, are simply not rising as the models had predicted, and the predictions were extravagantly baseless.

The overall picture is clear. Scenario A is the emissions scenario from 1990 that is closest to the observed emissions outturn, and yet there has only been a third of a degree of global warming since 1990 – about half of what the IPCC had then predicted with what it called “substantial confidence”.

clip_image014

Figure T4. Methane concentration as predicted in four IPCC Assessment Reports, together with (in black) the observed outturn, which is running along the bottom of the least prediction. This graph appeared in the pre-final draft of IPCC (2013), but had mysteriously been deleted from the final, published version, inferentially because the IPCC did not want to display such a plain comparison between absurdly exaggerated predictions and unexciting reality.

To be precise, a quarter-century after 1990, the global-warming outturn to date – expressed as the least-squares linear-regression trend on the mean of the RSS and UAH monthly global mean surface temperature anomalies – is 0.35 Cº, equivalent to just 1.4 Cº/century, or a little below half of the central estimate of 0.70 Cº, equivalent to 2.8 Cº/century, that was predicted for Scenario A in IPCC (1990). The outturn is visibly well below even the least estimate.

In 1990, the IPCC’s central prediction of the near-term warming rate was higher by two-thirds than its prediction is today. Then it was 2.8 C/century equivalent. Now it is just 1.7 Cº equivalent – and, as Fig. T5 shows, even that is proving to be a substantial exaggeration.

Is the ocean warming?

One frequently-discussed explanation for the Great Pause is that the coupled ocean-atmosphere system has continued to accumulate heat at approximately the rate predicted by the models, but that in recent decades the heat has been removed from the atmosphere by the ocean and, since globally the near-surface strata show far less warming than the models had predicted, it is hypothesized that what is called the “missing heat” has traveled to the little-measured abyssal strata below 2000 m, whence it may emerge at some future date.

Actually, it is not known whether the ocean is warming: each of the 3600 automated ARGO bathythermograph buoys somehow has to cover 200,000 cubic kilometres of ocean – a 100,000-square-mile box more than 316 km square and 2 km deep. Plainly, the results on the basis of a resolution that sparse (which, as Willis Eschenbach puts it, is approximately the equivalent of trying to take a single temperature and salinity profile taken at a single point in Lake Superior less than once a year) are not going to be a lot better than guesswork.

Fortunately, a long-standing bug in the ARGO data delivery system has now been fixed, so I am able to get the monthly global mean ocean temperature data – though ARGO seems not to have updated the dataset since December 2014. However, that gives us 11 full years of data. Results are plotted in Fig. T5. The ocean warming, if ARGO is right, is equivalent to just 0.02 Cº decade–1, or 0.2 Cº century–1 equivalent.

clip_image016

Figure T5. The entire near-global ARGO 2 km ocean temperature dataset from January 2004 to December 2014 (black spline-curve), with the least-squares linear-regression trend calculated from the data by the author (green arrow).

Finally, though the ARGO buoys measure ocean temperature change directly, before publication NOAA craftily converts the temperature change into zettajoules of ocean heat content change, which make the change seem a whole lot larger.

The terrifying-sounding heat content change of 260 ZJ from 1970 to 2014 (Fig. T6) is equivalent to just 0.2 K/century of global warming. All those “Hiroshima bombs of heat” are a barely discernible pinprick. The ocean and its heat capacity are a lot bigger than some may realize.

clip_image018

Figure T6. Ocean heat content change, 1957-2013, in Zettajoules from NOAA’s NODC Ocean Climate Lab: http://www.nodc.noaa.gov/OC5/3M_HEAT_CONTENT, with the heat content values converted back to the ocean temperature changes in fractions of a Kelvin that were originally measured. NOAA’s conversion of the minuscule temperature change data to Zettajoules, combined with the exaggerated vertical aspect of the graph, has the effect of making a very small change in ocean temperature seem considerably more significant than it is.

Converting the ocean heat content change back to temperature change reveals an interesting discrepancy between NOAA’s data and that of the ARGO system. Over the period of ARGO data, from 2004-2014, the NOAA data imply that the oceans are warming at 0.05 Cº decade–1, equivalent to 0.5 Cº century–1, or rather more than double the rate shown by ARGO.

ARGO has the better-resolved dataset, but since the resolutions of all ocean datasets are very low one should treat all these results with caution. What one can say is that, on such evidence as these datasets are capable of providing, the difference between underlying warming rate of the ocean and that of the atmosphere is not statistically significant, suggesting that if the “missing heat” is hiding in the oceans it has magically found its way into the abyssal strata without managing to warm the upper strata on the way. On these data, too, there is no evidence of rapid or catastrophic ocean warming.

Furthermore, to date no empirical, theoretical or numerical method, complex or simple, has yet successfully specified mechanistically either how the heat generated by anthropogenic greenhouse-gas enrichment of the atmosphere has reached the deep ocean without much altering the heat content of the intervening near-surface strata or how the heat from the bottom of the ocean may eventually re-emerge to perturb the near-surface climate conditions that are relevant to land-based life on Earth.

Most ocean models used in performing coupled general-circulation model sensitivity runs simply cannot resolve most of the physical processes relevant for capturing heat uptake by the deep ocean. Ultimately, the second law of thermodynamics requires that any heat which may have accumulated in the deep ocean will dissipate via various diffusive processes. It is not plausible that any heat taken up by the deep ocean will suddenly warm the upper ocean and, via the upper ocean, the atmosphere.

If the “deep heat” explanation for the hiatus in global warming were correct (and it is merely one among dozens that have been offered), then the complex models have failed to account for it correctly: otherwise, the growing discrepancy between the predicted and observed atmospheric warming rates would not have become as significant as it has.

It’s Official – There are now 66 excuses for Temp ‘pause’ – Updated list of 66 excuses for the 18-26 year ‘pause’ in global warming


  • Geologist

    There is just something absurd when a scientist calls someone a “denialist” because they have a diiferent opinion about data than someone else. I feel sad that some scientists have become so politicaly-motivated and agenda-driven that they disregard or dismiss other scientist’s view points out of hand and even rudely doing so.

    • P Gamble

      Interesting point, this could also be applied to those scientists who label others alarmist.

      • A. Sim

        Except P Gamble fails to identify that the latter group are not politically motivated; merely motivated by telling it straight, and who are inevitably determined to resist what is largely activist propaganda.

        Even a cursory glance at both “sides” of the debate richly demonstrate the EXTRAVAGANT bias and visceral theology of on the part of many of the Politicised alarmist camp.

        Objectivity requires an active suppression of the visceral yearning for what we wish to believe – and a truly honest and time-consuming analysis of viewpoints which we cannot comfortably stomach.

        The degree of deceit from (some) quarters of the alarmist “faithful believers” is both astonishing and disgraceful. If you havn’t noticed that then just listen to the (brief) Rupert Posner radio debate with Monckton (and copious similar exercises in alarmist obfuscation within other videos produced by both the alarmists and sceptics).

        I have watched/ listened scrupulously, and mutually-critically to a great deal of both “sides” of the debate; hence I am in a position to state my above comments.

        • A. Sim

          The disparity between the straight-talk of Sceptics (who have no motive), versus alarmist propaganda is so stark that, given enough time and effort, any truly impartial observer can see it shockingly clearly.

          In this context, the alarmists’ simple politicised tit-for-tat counter claims alleging that “it’s not us that’s politicking, it’s you” just dissolve in their own risibility.

          The politicised harnessing of bad science really is too blatant for that. The attempt to hoodwink the public by sleight of hand by politicised scientists who control the mainstream media is an international disgrace.

    • Kuni Leml

      The reason denialists are called denialists is because of crapola like their pretending that the RSS data covers the globe.

      The RSS data does not measure/track anything south of 70S and does not measure/track anything north of 82.5 degrees (an area that has seen significant temperature increases.)

  • cardigan

    Lord Monckton mentions Levitus et al 2012. The issue however, has been running for some considerable time before then and Kevin Trenberth started his search for his missing heat with a paper in 1994, 21 years ago. It first hit the mainstream in 2000, with a paper by S. Levitus, J.L. Antonov, T.P. Boyer, and Cathy Stephens, 2000. “Warming of the world ocean” Science, Vol. 287.

    That paper was critiqued here by the late and renowned oceanographer, Dr. Robert E. Stevenson with the title, “Yes, the Ocean Has Warmed; No, It’s Not “Global Warming”. It can be read here:
    http://www.21stcenturysciencetech.com/articles/ocean.html

    He went into great detail about the oceans and commented on the efforts to find the “missing heat” in the deep ocean.

    “For 15 years, (that was in 2000, so it’s now 30 years on that basis, as Hansen started on the warming theme before his famous 1988 address to Congress), modellers have tried to explain their lack of success in predicting global warming.

    The climate models had predicted a global temperature increase of 1.5°C by the year 2000, six times more than that which has taken place. Not discouraged, the modellers argue that the heat generated by their claimed “greenhouse warming effect” is being stored in the deep oceans, and that it will eventually come back to haunt us.

    They’ve needed such a boost to prop up the man-induced greenhouse warming theory, but have had no observational evidence to support it. The Levitus, et al. article is now cited as the needed support.

    The concept proposed in some predictive models is that any anomalous heat in the mixed layer of the ocean (the upper 100 meters) might be lost to the deep ocean.

    There have been a number of studies in which this process has been addressed (Nakamura 1997; Tanimoto 1993; Trenberth 1994; Watanabi 1994; and White 1998).

    It is clear that solar-related variations in mixed-layer temperatures penetrate to between 80 to 160 meters, the average depth of the main pycnocline (density discontinuity) in the global ocean. Below these depths, temperature fluctuations become uncorrelated with solar signals, deeper penetration being restrained by the stratified barrier of the pycnocline.

    Consequently, anomalous heat associated with changing solar irradiance is stored in the upper 100 meters. The heat balance is maintained by heat loss to the atmosphere, not to the deep ocean.”

    (Stevenson was Secretary General of the International Association for the Physical Science of the Oceans from 1987 to 1995, and worked as an oceanographer for the U.S. Office of Naval Research
    for 20 years.)

    I have only some questions for every one to ponder:

    Q1) Ok so its now 18 years and 4 months. So how many years and months must pass by before we end this foolishness about global warming? 20? 30? 50? Seriously, how long does all this nonsense must go on before we say, “there is no global warming.” Can we at least get or force the crooked governments, lunatic IPCC, fraudster scientists, to all put their laws, reputations, money and grants on the line, so that after an irrefutable amount of time has passed by, we can say that there is no global warming at all? Can we at least force this issue, by setting a time period? I mean after all, if the morons of the scientific community can use an opportunistic determined length of time of rising temperatures during the 20th century to “declare” a global warming catastrophe, then by the same “logic” if an equally or even longer period of no temperature change, or even decreasing temperature change were to occur you’d think that by the same “logic” that there is no global warming. So what’s the magic number? And once we have reached it, can we finally close this climate hypochondriac madness. Or do we have to go through an entire nefarious mischievousness like South Sea Bubble or Salem Witch Mania, where economies ended up in ruin or many people ended up being killed all because of greed and superstitions, by in our case, moronic incompetent scientists who have no idea how to do their jobs and corrupt governments who are too gutless and selfish to do the right thing?

    Q2) So out of the over 100 climate simulations, all but perhaps one simulation (which is very much on the verge now beginning to diverge too), from these best simulations are showing signs of being so wrong that your odds of winning at the roulette, as for the worse of the sims, they are so bad that you are more likely of wining the lottery every week for the next 1,000 years than getting anything those sci-fi sims are saying. What needs to transpire for junk science to stop and be tossed on the garbage heap? If you had these same climate simulation idiots doing a Formula 1 car simulation, the equivalent car performance they’d be coming up with, would be something closer to Ford’s 1950’s Edsel, than a 2015 Formula 1 Mercedes or Ferrari that they were trying to sim. out. Think about it, we have 2015 Formula 1 cars, but the morons in the climate simulation business are telling us they are simulating something akin to a 50’s Edsel? How wrong can you be, before you junk the sim. and release you don’t know what you are doing? Would any self respecting engineering company, or financial house ever hire anyone of these incompetents that worked on a global warming sim.? Note to all you global warming scientists, and simulator programmers, I’ll never hire you. Its one thing to be part a project that is failing, but to not be able to understand that what you are doing is a complete waste of time, that shows idiocy or corruption, for that, you do not work in a business where people’s lives and money is at risk!

    We are into the 19th year, that at least can be called a climate pause, but more actually is a slight cooling trend. La Nina is a bust. Next El Nino looks like is going to be a whopper. Solar activity is going into hibernation like a bear. Speaking of bears, polar bears are populating like Australian rabbits. Antarctica surface AND volume ice extent is at record highs and expanding, so much so that the South Orkney Islands are icing in faster and more heavily since the last LIA, and the ice is extending further out every season towards South Georgia! The Arctic sea ice extent has never cleared, and is holding its own. Glaciers all around the world have started growing again, in some places like Scotland, signs of glacier growth are becoming evident where there hasn’t been a glacier for centuries! Greenland is depopulating like they did several hundred years; what happened to all those well laid plans of growing oranges and pineapples? But then there is California with its drought. Drought? Say what? Here is a question for all you liberal non showering stinking wack jobs, if you minus 39 million people from California, what do you get? I will tell you, you will get a California that was like in 1600, where there would trees every where, wildlife everywhere, flora everywhere, salmon in all the rivers, and LOTS AND LOTS OF WATER, that is, NO DROUGHT. 39 million people in California; now we know the carrying capacity of California, its WAY less than 39 million.

    Listen you Californians, could you please put a sign on yourselves when you travel saying you are from California, I have no desire to be anywhere near you! Its bad enough in San Francisco, that place stinks like Venice, Italy. But if you Californians are going to bring San Francisco everywhere you go, that’s something else all together!

    Tip for Californians: Well if you can’t shower anymore, at least you’ll have almonds, take some and put them a blender, and turn them into a paste, then rub liberally all over your body. That way when you go travelling at least you’re not going reek of stench. Oh, but stay away from countries where there are camels!

    AH, Global Warming Morons, could this have been what Darwin was talking about? 39 million thirsty Californians and getting thirstier every season. So where is the US going to get water from to fill California.

    Oh Canada, I hope you are paying attention. I guess a water pipeline from British Columbia is a lot cheaper and way more supportive than an oil pipeline. Question is, how many lakes are you prepared to drain to supply 39 million people, a population that is more than entire Canada!

    Well this is going to be interesting. The USA turned Arabs into terrorists to get oil, I wonder what Canadians will be turned into when the USA comes after “its” water!

    Ah yes, we do live in interesting times.

    Let the Water Wars begin!

      35 years should do it. maybe…

    In 18 years, or even 30, climate trends are not discernable. Apparently Lord Monckton’s classics education was insufficient for science, because he thinks the ‘pause’ is evidence contradicting AGW. It isn’t, nor does any scientist in the field think so.

      Then why did Hanson declare the planet was warming in the first few years of the warm up following the 30 year cooling period of the 50’s, 60’s, 70’s, 80’s?

        Post the full direct quote by Hansen, please.

          Global Warming Has Begun, Expert Tells Senate

          By PHILIP SHABECOFF, Special to the New York Times

          Published: June 24, 1988

          WASHINGTON, June 23— The earth has been warmer in the first five months of this year than in any comparable period since measurements began 130 years ago, and the higher temperatures can now be attributed to a long-expected global warming trend linked to pollution, a space agency scientist reported today.

          Until now, scientists have been cautious about attributing rising global temperatures of recent years to the predicted global warming caused by pollutants in the atmosphere, known as the ”greenhouse effect.” But today Dr. James E. Hansen of the National Aeronautics and Space Administration told a Congressional committee that it was 99 percent certain that the warming trend was not a natural variation but was caused by a buildup of carbon dioxide and other artificial gases in the atmosphere.

          Dr. Hansen, a leading expert on climate change, said in an interview that there was no ”magic number” that showed when the greenhouse effect was actually starting to cause changes in climate and weather. But he added, ”It is time to stop waffling so much and say that the evidence is pretty strong that the greenhouse effect is here.” An Impact Lasting Centuries

          If Dr. Hansen and other scientists are correct, then humans, by burning of fossil fuels and other activities, have altered the global climate in a manner that will affect life on earth for centuries to come.

          Dr. Hansen, director of NASA’s Institute for Space Studies in Manhattan, testifed before the Senate Energy and Natural Resources Committee.

          He and other scientists testifying before the Senate panel today said that projections of the climate change that is now apparently occurring mean that the Southeastern and Midwestern sections of the United States will be subject to frequent episodes of very high temperatures and drought in the next decade and beyond. But they cautioned that it was not possible to attribute a specific heat wave to the greenhouse effect, given the still limited state of knowledge on the subject. Some Dispute Link

          Some scientists still argue that warmer temperatures in recent years may be a result of natural fluctuations rather than human-induced changes.

          Several Senators on the Committee joined witnesses in calling for action now on a broad national and international program to slow the pace of global warming.

          Senator Timothy E. Wirth, the Colorado Democrat who presided at hearing today, said: ”As I read it, the scientific evidence is compelling: the global climate is changing as the earth’s atmosphere gets warmer. Now, the Congress must begin to consider how we are going to slow or halt that warming trend and how we are going to cope with the changes that may already be inevitable.” Trapping of Solar Radiation

          Mathematical models have predicted for some years now that a buildup of carbon dioxide from the burning of fossil fuels such as coal and oil and other gases emitted by human activities into the atmosphere would cause the earth’s surface to warm by trapping infrared radiation from the sun, turning the entire earth into a kind of greenhouse.

          If the current pace of the buildup of these gases continues, the effect is likely to be a warming of 3 to 9 degrees Fahrenheit from the year 2025 to 2050, according to these projections. This rise in temperature is not expected to be uniform around the globe but to be greater in the higher latitudes, reaching as much as 20 degrees, and lower at the Equator.

          The rise in global temperature is predicted to cause a thermal expansion of the oceans and to melt glaciers and polar ice, thus causing sea levels to rise by one to four feet by the middle of the next century. Scientists have already detected a slight rise in sea levels. At the same time, heat would cause inland waters to evaporate more rapidly, thus lowering the level of bodies of water such as the Great Lakes.

          Dr. Hansen, who records temperatures from readings at monitoring stations around the world, had previously reported that four of the hottest years on record occurred in the 1980’s. Compared with a 30-year base period from 1950 to 1980, when the global temperature averaged 59 degrees Fahrenheit, the temperature was one-third of a degree higher last year. In the entire century before 1880, global temperature had risen by half a degree, rising in the late 1800’s and early 20th century, then roughly stabilizing for unknown reasons for several decades in the middle of the century. Warmest Year Expected

          In the first five months of this year, the temperature averaged about four-tenths of a degree above the base period, Dr. Hansen reported today. ”The first five months of 1988 are so warm globally that we conclude that 1988 will be the warmest year on record unless there is a remarkable, improbable cooling in the remainder of the year,” he told the Senate committee.

          He also said that current climate patterns were consistent with the projections of the greenhouse effect in several respects in addition to the rise in temperature. For example, he said, the rise in temperature is greater in high latitudes than in low, is greater over continents than oceans, and there is cooling in the upper atmosphere as the lower atmosphere warms up.

          • Warren

            This is what Hansen is quoted as saying: ”The first five months of 1988 are so warm globally that we conclude that 1988 will be the warmest year on record unless there is a remarkable, improbable cooling in the remainder of the year,”
            His quote does not allude to the length of time necessary to determine a climate trend.

          • Eve Stevens

            Correct, he did not give a length of time necessary to determine a climate change. You are the one asking for it.

          • Warren

            Hansen didn’t even discuss the issue I brought up — “18 months is not enough to discern a climate trend” — so why did you bring up what Hansen said?

          • Eve Stevens

            Because Hanson deliberately held a meeting about global warming the first year of warming following 30 years of cooling. He held it on a warm day and had the air conditioning turned off. I know he is an astronomer but…

          • Warren

            Your point seems irrelevant to anything about AGW.

          • Eve Stevens

            then I can only laugh
