Enthusiasm about a Double-Dip El Niño (?) And Global Warming

Guest Post by Bob Tisdale

In this post we can learn from someone’s mistakes. The author of the post at Slate clearly misunderstands many aspects of El Niño and their relationship with the Pacific Decadal Oscillation…so many that I’ve had to focus on just a few. To confuse matters more, mixed in with those misunderstandings are realities and quotes from ENSO researchers. But first…


I first ran across the term “global warming enthusiast” in a June 2012 article in The Sunday Times written by the always-entertaining Jeremy Clarkson, who is best known for his antics in the BBC’s Top Gear. The article by Clarkson was Kaboom! It’s my turn to play fantasy climate change. (Paywalled.) Also see the ClimateRealists webpage here. There Jeremy Clarkson wrote:

Science fiction is thriving; only today it’s all being written by global warming enthusiasts.

I’ve used the phrase “global warming enthusiast” in numerous blog posts and in many more comments around the blogosphere since I found that Clarkson article. Occasionally, someone will respond to it with something to the effect of No one is enthusiastic about anthropogenic global warming. Bad things will happen because of it. That always sounded like more science fiction to me.

Well, a recent article indicates there are people enthusiastic about the return of global warming: See An El Niño Double-Dip? at the Slate.com. (A double-dip El Niño? That’s a very odd term. I’ll explain in a moment.) The article begins:

Global warming is about to get a boost.

As this year’s El Niño sets in, early signs are pointing toward the possibility of a rare occurrence: back-to-back El Niño years. If it happens, it would virtually guarantee a new global heat record in 2015 and could help usher in a decade or more of accelerated warming.

The author sounds awfully enthusiastic about the thought of “a decade or more of accelerated warming.” The only thing missing is an exclamation like Yippee!

But the author’s enthusiasm is overshadowed by his misunderstandings, conjectures and blatant errors. But good things can come from them. People who want to learn can learn, and those who don’t won’t.


The title of the article is very strange: “An El Niño Double-Dip?” Sorry. The phrase double-dip was applied to the La Niña events of 2007/08 and 2008/09 and the La Niña events of 2010/11 and 2011/12 because there were back-to-back dips (cooling) in the sea surface temperatures of the eastern equatorial Pacific, separated by off-season ENSO-neutral conditions. See Figure 1.

Figure 1

Figure 1

Or if you’d prefer data presented in tables, see the annotated screen cap of the NOAA Oceanic NINO Index (ONI) in Figure 2.

Figure 2

Figure 2

Double-dip would not apply to back-to-back El Niños separated by ENSO-neutral conditions, because those would be rises in the sea surface temperatures of the equatorial Pacific. If someone’s looking for alliteration, they could try repeated-rise El Niños, not double-dip.

I’m not being pedantic about the difference between multiyear and back-to-back El Niño events. El Niño events are tied to the seasonal cycle, also known as phase locking, and as a result they normally peak in boreal winter and decay into boreal spring. See the post Why Do El Niño and La Niña Events Peak in Boreal Winter? An El Niño that does not decay in boreal spring, but lasts through to a second season, defies the seasonality of El Niños.

To further compound the oddness of the headline, the author uses as a reference the NOAA CFSv2 modeled sea surface temperature anomaly forecasts for the NINO3.4 region of the equatorial Pacific, dated October 14, 2014. See Figure 3. The mean of the forecast (dashed black curve) remains elevated, above the El Niño threshold of 0.5 deg C, through May-June-July, which is the ENSO off-season. What’s missing? The return to ENSO neutral conditions in the off-season. It’s absence would suggest a multiyear El Niño, not a back-to-back one.

Figure 3

Figure 3

Also, the author must not be familiar with the “spring predictability barrier” for ENSO forecasts. See of Torrence and Webster (1997) The annual cycle of persistence in the El Niño/Southern Oscillation. The first two paragraphs of it read:

A spring ‘predictability barrier’ exists in both data and models of the El Niño/Southern Oscillation (ENSO) phenomenon. In statistical analyses this barrier manifests itself as a drop-off in monthly persistence (lagged correlation) while in coupled ocean-atmosphere models it appears as a decrease in forecast skill.

The ‘persistence barrier’ for ENSO indices is investigated using historical sea surface temperature and sea level pressure data. Simple statistical models are used to show that the persistence barrier occurs because the boreal spring is the transition time from one climate state to another, when the ‘signal-to-noise’ of the system is lowest and the system is most susceptible to perturbations. The strength of the persistence barrier is shown to depend on the degree of phase locking of the ENSO to the annual cycle.

References to the “spring predictability barrier” can be found in papers from the early 1990s, and the barrier still exists for forecasters.

Bottom line: ENSO forecasts are notoriously unreliable through boreal springtime.

Q: Are back-to-back El Niño events possible, with ENSO-neutral conditions separating them?

A: Yes, according to NOAA Oceanic NINO Index (ONI), a pair occurred in 1957/58 and 1958/59 and another pair happened in 1976/77 and 1977/78.

Q: Are multiyear El Niño events possible, without a return to ENSO-neutral conditions during what would normally be considered the ENSO off-season?

A: Yup, the 1986/87/88 and 1969/70/71 El Niño events are examples.

Q: Has the NOAA CFSv2 model shown any skill at predicting back-to-back or multiyear El Niños?

Nope, sadly it’s too new to have a track record. The NCEP Climate Forecast System Version 2 (CFSv2), according to the linked webpage, “became operational at NCEP in March 2011.” And according to the NOAA Oceanic NINO Index (ONI), there have been no El Niño events, of any kind, since the CFSv2 became operational.

I don’t recall. Was the CFSv2 one of the models that forecast an El Niño for the 2012/13 season? If that’s the case, it highlights one of the problems with ENSO forecasting. The events can be far and few between, so if you miss one, it’s not good for your batting average. Hmm. I wonder what Bob Eucker would say about stats like that. (Sorry, Uke.)


On the Pacific Decadal Oscillation, the author of the Slate post writes (my boldface):

Even if there’s not a second El Niño, a longer-term climate signal is beginning to point in the direction of more frequent bursts of warming over the next several years. Over the next few years, a natural climate oscillation known as the Pacific Decadal Oscillation (PDO) is poised to kick into gear. Historical data has linked the “warm” phase of the PDO with a 15- to 30-year temporary surge in global temperatures. A new paper even shows this sort of natural variability could trump long-term human-caused climate warming in localized areas like the Pacific Northwest.

The PDO can be thought of as the atmospheric manifestation of a stretch of frequent El Niño events. If El Niño is the spark that ignites a months-long transfer of heat between the ocean and the atmosphere, the PDO is an indicator of how much fuel is in the gas tank.

The author of the Slate post clearly has no idea what the PDO is all about.

We recently discussed the Pacific Decadal Oscillation in minute detail in the post The 2014/15 El Niño – Part 5 – The Relationship Between the PDO and ENSO. The PDO Index is a numerical representation of the spatial pattern in the sea surface temperature anomalies of the extratropical North Pacific (northward of 20N), where a positive PDO spatial pattern has warmer sea surface temperature anomalies in the eastern extratropical North Pacific (along the coast of North America) than in the central and western North Pacific (the Kuroshio-Oyashio Extension). That spatial pattern is typically created by strong El Niño events. A positive PDO index value basically represents how closely the spatial pattern of the sea surface temperature anomalies of the extratropical North Pacific matches those created by strong El Niños. The higher the number, the closer the match. Conversely, a negative PDO Index value relates to the pattern created by La Niñas. The PDO Index values have different variations in time than those of an ENSO index (like NINO3.4 sea surface temperature anomalies) because the spatial patterns in the surface temperatures of the North Pacific are also impacted by the sea level pressures (and related wind patterns) there.

Contrary to the mistaken beliefs of the author of the Slate post, the PDO cannot “be thought of as the atmospheric manifestation of a stretch of frequent El Niño events”. The PDO index is derived from sea surface temperatures.

And the PDO is definitely not “an indicator of how much fuel is in the gas tank…” for El Niños. For that one must refer to the ocean heat content data for the tropical Pacific. See Figure 4, which is from the post The 2014/15 El Niño – Part 2 – The Alarmist Misinformation (BS) Begins.

Figure 4

Sorry to disappoint the author of the Slate post, but the warm water available for El Niños has dropped in recent years.

And the author of the Slate post gets something kind-of right, but obviously has no grasp of reality (my boldface).

Even if there’s not a second El Niño, a longer-term climate signal is beginning to point in the direction of more frequent bursts of warming over the next several years. Over the next few years, a natural climate oscillation known as the Pacific Decadal Oscillation (PDO) is poised to kick into gear. Historical data has linked the “warm” phase of the PDO with a 15- to 30-year temporary surge in global temperatures.

It’s very odd that a global warming enthusiast would parrot something that skeptics pointed out about a decade and a half ago. Unfortunately, there is no mechanism through which the PDO (as represented by the JISAO definition of the PDO) can cause global surface temperatures to warm. The PDO index is actually inversely related to the sea surface temperatures of the region from which it’s derived.

The processes that cause the PDO are the same processes that cause natural (sunlight-fueled) global warming or suppress it, and those processes are the ones associated with El Niño and La Niña events.

In the past I’ve written: The strength of ENSO phases, along with how often they happen and how long they persist, determine how much heat is released by the tropical Pacific into the atmosphere and how much warm water is transported by ocean currents from the tropics toward the poles. During a multidecadal period when El Niño events dominate (a period when El Niño events are stronger, when they occur more often and when they last longer than La Niña events), more heat than normal is released from the tropical Pacific to the atmosphere and more warm water than normal is transported by ocean currents into adjacent ocean basins and toward the poles—with that warm water releasing heat to the atmosphere along the way. As a result, global sea surface and land surface air temperatures warm during multidecadal periods when El Niño events dominate. They have to. There’s no way they cannot warm.

Maybe it’s easier to think of the long-term impact of ENSO another way. During multidecadal periods when El Niño events dominate, atmospheric and ocean circulation become hyperactive, leading to a long-term, naturally caused, sunlight-fueled global warming.

Also, during multidecadal periods when La Niña and El Niño events are more evenly matched, as they have been for the past decade, atmospheric and ocean circulation become more balanced, leading to the cessation of the long-term, naturally caused, sunlight-fueled global warming.


Focusing on the mean again, the most recent forecast for NINO3.4 sea surface temperature anomalies from the NCEP CFSv2 model, Figure 5, shows a decline in the temperatures there over the next few months, meaning no El Niño this season, which would mean no back-to-back El Niños and no multiyear El Niño. See the NOAA Weekly ENSO Update (page 26).

  1. Sorry if this is a little off topic however:
    Some commenters, no doubt, will describe Clarkson in very poor terms. However he is a very good paper journalist. His Arctic convoy documentary is quite excellent, and there are others. As regards the convoy documentary, no doubt it is available on YouTube. Everyone should watch it.

    • Sorry, Andrew, I found his Arctic convoy film poorly researched, as did a friend of mine who served in those waters at that time.
      Clarkson concentrated mostly on RN people.

    • Hi Andrew. So far, there haven’t been any objections to Mr. Clarkson’s name appearing in my post or to my quoting him.
      I’ll agree that Clarkson is an excellent journalist. I may not always agree with his conclusions, but I always enjoy how he reaches them.

        • Prudie deals with climate issues routinely, like here:

          Nuttyville, U.S.A.: Dear Prudie,
          I hope you can help. The past few years my wife has been making changes for what she believes is going to be some kind of life altering event in the near future. Whether it be due to global warming …

          And here:

          In a live chat, Prudie counsels a man driven to lustful extreme:
          After her shower, she says she gets overheated easily while we’re both getting ready for work … she basically just goes about her morning routine with barely any clothes on …

    • The author of the Slate article is Eric Holthaus, who bills himself as a meteorologist. I can’t find his education or credentials anywhere, but at any rate, there are plenty of meteorologists who have consumed the watermelon Red kool-aid, and are faithful Climate Change believers, regardless of the data and the falsification of the GCMs, regardless of the Pause. For Guys like Eric, they have faith in Climate Science that can’t be shaken by real-world data that Climate Change due to man-made CO2 is not happening.
      At any rate, if he is a real meteorologist, then as Bob shows, Eric’s understandings of the various cycles in the Pacific Ocean are deficient.
      In one of his other more recent posts at Slate, Eric “The Red” Holthaus actually calls for no more IPCC reports, since his Faith in CAGW leads him to believe that the science is settled, and it is time to act. Yawn.
      I know many here at WUWT wholeheartedly agree that there should be no more IPCC ARs, but for the opposite reason. The IPCC’s use of science and climate models are fatally flawed by self-serving political motivations.

  2. You have to realize this was a sermon to try and pump up the flock. Being factually correct is not important.

  3. The ting about warmists is that they double count El-Ninos for their purposes. When there isn’t one they say (rightly) that the ocean is accumulating heat. But when there is one they cry “Alarm” the world is melting when in fact what the world is doing is cooling down by releasing the heat from the oceans into the atmosphere and then into space.
    El_ninos??? bring ’em on. The more the merrier.

  4. Apparently I’m confused. I thought we were in a cool PDO phase, with more la nina’s, not a warm PDO.

    • Clearly the Slate writer is a climate boob. Yes, we are in the cool phase of the PDO, so it’s absurdly ignorant for a CACA enthusiast to welcome what’s “about to kick in” in the North Pacific.
      As I write, a warm front is energetically pushing through my native PNW, an early harbinger of the Pineapple Express & Chinooks we can expect this winter, no matter how cold.

  5. I love reading posts from Bob, he has clearly has tons of knowledge on climate science. But some tough love, he could improve on getting on his messages across more clearly and concisely. To criticize using the term double dipping when it would be more appropriate to say back to back rise is a nit pick, and distracts from the discussion of the real errors. Many people use the term double dip for for items that aren’t increases, douple dip inflation etc., its not appropriate but I would like Bob to try and focus on starting his messages with the biggest, most important points he has, in this case the biggest error he found. I myself read that he had a list of misunderstandings of what PDO is, read that he was criticizing the use of the term double dip, and found myself thinking “this is a nit pick list, there isn’t going to be any substantial criticism of the science”, but you have to read more to see that is not true. Don’t assume all readers will read all of your posts, you need to grab them with a whopper first to keep them interested, if they see a minor issue noted they will likely assume the rest are even less substantial.

    • Bob needs to at least dot point his conclusions. I have said it many times. I’m sure a lot of people including me don’t have the time to extract the nuggets from his usually long articles and seemingly endless graphs in other posts.

  6. ” according to NOAA Oceanic NINO Index (ONI), a pair occurred in 1957/58 and 1958/59 and another pair happened in 1976/77 and 1977/78.”
    Hmmm, and in 1997/98 we had the big one. Could the back to back pair release as much energy as the one big one? I know the data set is limited and just my SWAG that there appears to be a 20 year period for large heat exchange events. Maybe it only happens in the positive phase of the PDO?
    I could be hallucinating the whole thing as well 🙂

    • Those double El Nino in the 1950s took place on the rise from the solar minimum between cycle 18/19. There was a big flood event in the PNW in 1955/56 during the low of that minimum.Then cycle 19 became the highest solar peak on the chart in the 3 years following that minimum.

      • The winter of 1955/56 in the PNW was quite cold and snowy. Our family snow skied many times at elevations between 3,000 and 4,000 feet that winter in southeastern Washington State.

        • That winter was also saw a major flood event on the coast of the PNW. Washington St may not have got hit as hard as Oregon and California did during that flood event. The storm track might have been centered on southern Oregon.

  7. Thanks, Bob.
    Today the NOAA-NWS Climate Prediction Center – CPC, ENSO Diagnostic Discussion – 6 November 2014 says:
    “There is a 58% chance of El Niño during the Northern Hemisphere winter, which is favored to last into the Northern Hemisphere spring 2015.”
    “During October 2014, above-average sea surface temperatures (SST) increased slightly across the eastern half of the equatorial Pacific (Fig. 1). The weekly Niño indices were between +0.6°C (Niño-3.4 and Niño-1+2) and +0.9°C (Niño-3) at the end of the month (Fig. 2).”
    See ENSO Diagnostic Discussion – 6 November 2014, at http://www.cpc.ncep.noaa.gov/products/analysis_monitoring/enso_disc_nov2014/ensodisc.html
    But, the ESRL-PSD: Multivariate ENSO Index (November 5 ’14, Klaus Wolter, NOAA) shows:
    This is a very mild and declining El Niño event.

  8. Bob: Are there any good studies of the rate of movement of warm and cold water around the No. Pacific. It seems to me that the relative warmth of the California current now must be water that went north in the Kuroshio at some point in time (I realize that upwelling/downwelling also may be involved). Surely we have means of tracking these things with markers of some sort? If the rate of flow varies significantly over time, the timing of subsequent changes could speed-up/lag and affect other changes.

  9. Speaking of Global Warming Enthusiasts taking umbrage. An oldie, but a goodie. In a BBC Documentary, Broadcast Date: 25.01.10, Solitaire Townsend Co-founder and Chief Executive of Futerra Sustainability Communications had this to say.
    “TOWNSEND: I was making a speech to nearly 200
    really hard core, deep environmentalists and I played
    a little thought game on them. I said imagine I am the
    carbon fairy and I wave a magic wand. We can get rid
    of all the carbon in the atmosphere, take it down to
    two hundred fifty parts per million and I will ensure
    with my little magic wand that we do not go above
    two degrees of global warming. However, by waving
    my magic wand I will be interfering with the laws of
    physics not with people they will be as selfish, they
    will be as desiring of status. The cars will get bigger,
    the houses will get bigger, the planes will fly all over
    the place but there will be no climate change. And I
    asked them, would you ask the fairy to wave its
    magic wand? And about 2 people of the 200 raised
    their hands.”

  10. No one is enthusiastic about anthropogenic global warming.
    Then why do so many get so upset when evidence comes out that it is not or will not be as bad as feared? Why do they circle the wagons whenever the narrative gets interrupted?

  11. If it’s got two humps, it’s a Bactrian el Niño, and from what Bob says, relatively rare, like the camel of the same name.

  12. “Figure 5, shows a decline in the temperatures there over the next few months, meaning no El Niño this season…”
    Wasn’t it just last week that Bob was asking “Is an El Niño Already Taking Place?” And wasn’t he agreeing with Joe Bastardi that a weak to moderate El Niño was coming? Now it’s “no El Niño this season.” What a difference a week makes! Will it change again next week?

      • Bob, I guess I was confused. I quoted from the “Closing Note” paragraph at the end of your article and assumed it was your opinion being expressed. Usually, an author summarizes his conclusions at the end. In the future, if you do not agree with your own closing paragraph, please tell us to avoid confusion.

  13. Bob,
    I am confused as to what you think is happening. You write “more heat than normal is released from the tropical Pacific to the atmosphere and more warm water than normal is transported by ocean currents into adjacent ocean basins and toward the poles—with that warm water releasing heat to the atmosphere along the way. As a result, global sea surface and land surface air temperatures warm during multidecadal periods when El Niño events dominate.” This sounds like you are saying that the late 20th century warming was due to net heat transfer from the ocean to the atmosphere. But that can’t be, since the data show that the heat content of the ocean increased strongly during that period.
    Or are you, like Roy Spencer, suggesting that the redistribution of heat cause a change in patterns of cloudiness, resulting in a change in solar radiative forcing? And that the extra forcing is mostly in the tropical Pacific, with the above process redistributing the heat? That is plausible, though unproven.
    Mike M.

    • Mike M. says: “This sounds like you are saying that the late 20th century warming was due to net heat transfer from the ocean to the atmosphere.”
      Hi Mike M. You forgot a portion of the quote from my post. “…and more warm water than normal is transported by ocean currents into adjacent ocean basins and toward the poles—with that warm water releasing heat to the atmosphere along the way.” I

      • Bob,
        I did not forget that and don’t see why you think I forgot that. What is the source of that heat?
        Mike M.

    • Mike M.
      “This sounds like you are saying that the late 20th century warming was due to net heat transfer from the ocean to the atmosphere. But that can’t be, since the data show that the heat content of the ocean increased strongly during that period.”
      If net cloud albedo decreases and everything else is held constant, the oceans can warm while transferring more heat upwards.

  14. Not to be a wise guy, but why use the very poor CFSV2. If you are going to look at it now, then why not show its super nino from April. It stunk
    The prime sites for my money, and both of them do not see AGW my way, are Scripps and JAMSTEC. both have been much much closer to the correct idea, both of them forecasting continually a weak to moderate event that becomes centered in 3.4 and 1.2. This is very similar to the winters of the late 1970s where a triple dip la nina was followed by the double spike enso event, though THEY WERE WEAK. The northeast pacific warm pool which will weaken and flip in the coming years in as important as this event.
    The la ninas followed by the enso event are part of an MEI bounceback theory for cold US winters. Such events like 02-03 and 09-10, as well as the late 70s are examples
    The problem with the AGW ilk is they do not realize that whatever spike they get here will be followed by a bigger downturn, as the natural cyclical swings continue to cool the planet till the PDO flips back warm IN THE DECADE SENSE in 25 years or so. The NCEP ( I believe they are apart of NOAA, strangely ignored though when it comes to reporting global temps) site shows the downturn that has begun in a jagged fashion and whatever spike they get here, will be reversed greatly with in 2-3 years
    one has to wonder what world they live in screaming warmest ever when NCEP, RSS and UAH plainly show otherwise with better gridding and a site not tainted by “adjustments” of temperatures in the previous warm times

  15. Re: “global warming enthusiast”
    Over at:
    You will find this link
    NASA Satellites Detect Pothole on Road to Higher Seas
    Where they say:
    “While the rise of the global ocean has been remarkably steady for most of this time, every once in a while, sea level rise hits a speed bump. This past year, it’s been more like a pothole: between last summer and this one, global sea level actually fell by about a quarter of an inch, or half a centimeter. ”
    The slowdown in sea level was regarded as a speed bump or pothole. It wasn’t a moratorium, reprieve, remission, or any other term normally used to describe avoidance of unpleasant events. Nope, it can’t be denied the folks at CU’s Sea Level Research Group do indeed want sea level rise to continue upward and accelerate to boot
    This link
    Why has an acceleration of sea level rise not been observed during the altimeter era?
    is proof of that.
    So yes Virginia, the Left-Wingers in this world really do crave catastrophic disaster. It can’t come soon enough for them.

    • Their professional reputations are now at grave risk with the incipient Global Cooldown looming within 2 years. They’ve been calling for the sky to fall for so long, that if it doesn’t they are toast.
      The Alarmists have been hoping for some kind of CO2 emissions deal to show the public that a slowdown of CO2 emissions to coincides with the cool-down, even though the coming cooldown is a natural variation. They are about to get the cool-down and no slow down of man’s CO2 emissions. That will contradict everything they have said in 25+ years of alarmism.
      And so they are Global Warming Enthusiasts, hoping for a a few more years of at least Pause to get a CO2 deal in place.

    • Steve Case: ” or a half a centimeter”
      Which is about 5 mm. Seems fishy.
      Do you not think it strange that sea level should be rising one year at 3 mm/year and then suddenly start falling at 5 mm/yr. without a period of slowing, then a flat trend, then a gradual reversal building up to the 5 mm rate of decline? I repeat, something fishy. It seems more likely that the U of Colo. fabricated rate of SL rise got too far ahead of the truth and an adjustment was needed. They are nothing but f-words at that place.

      • There is lots of strange stuff going on in the world of climate science. There has been so much manipulation of the Satellite record that it’s difficult to decide what may actually be close to the truth. Thanks for the comment.

  16. A “double dip” is a widely-used idiomatic expression referring to the socially unacceptable act of dipping a food item into a condiment, eating a part of the item, and then returning it to the bowl for a second dip of condiment mouth germs and all. It is, in fact, an entirely appropriate term for a sequence of two occurrences of an undesirable thing. At least when not taken literally to try to create a strawman.

  17. All I know is the so called cooling hasn’t really happened although many have subscribed to it for some years . I do find Bob’s articles full of information but never seemingly any conclusion or direction. The same with Joe.
    From Bob and Joe where are we with both the Atlantic and the pacific are the in a cooling phase or warning phase as it seems to chop and change with every article or is it that I’m too thick to understand what’s being said. However if we agree that I’m thick and there are many like me so therefore can we have a clear statement as to the
    State of the ocean phases
    Are sea temperatures overall climbing or falling.
    So Joe and Bob for the public in general where the hell are we regarding all these PDO’s ENSO’s AMO and so on.. Joe argues that the oceans contain a thousand times more energy than the atmosphere so does that mean that overall the oceans have caused the twentieth century warming as they slosh about and overturn and wi9ll those same ocean herald a cooling as its all just a matter of heat distribution in the oceans that yje overall heat never really changes it just moves about a lot.

  18. Of course the Global Warming Enthusiasts would be jumping for joy at an El Nino because the plateau in global temperature is so inconvenient. A burst of warming before the Paris GWE bunfest would have them all saying ‘see, told you it was a pause’ and a scientific explanation for a small blip in the flat-lining temps would never make it to the lame media.

  19. If Nino 3.4 stays positive over Christmas then it might bring about a strong La Nina in early 2015.
    The threshold for el Nino / La Nina should be +/- 1 degree anomaly of Nino3.4 not 0.5 degrees.

  20. The sad fact is, we are unquestionably in Negative PDO land, and El Nino will always be running uphill and against the wind (both figuratively and literally). I’m danged glad Prop 1 passed (queue brickbats from would be State of Jefferson Founding Fathers). For California (at least for the next 20 – 40 years) it is a brave new world and a dry one at that.

    • Here is a piece of the arguments made by opponents, “”It’s a retread of previously discredited programs that allowed speculators to reap millions in profit selling the public’s water back to the public. “”.
      You think that this sounds like a great deal?

  21. As usual a highly informative article by Tisdale, who seems tireless in exposing gross ignorance, and faulty reasoning related to climate science.
    Slate politically is what I call a Neanderthal site. Some of the articles and reporting is very interesting. Their political reporting, or any issues viewed left vs. right has the rigor of thought equivalent to cavemen beating their chests and exclaiming, “We good, them bad”. Not quite as Neanderthal as The Guardian whose climate reporting reaches cosmic levels of incompetence mixed liberally (pun intended) with desperate attempts at melodrama. Salon politically became a brainless water carrier for the DNC and lost any capability for investigative journalism or intellectual relevance a while ago.
    BTW not saying there are not similar sites on the right. It is just more irksome when the left does it, since they are the self-described “smart” ones, pro-science, rational thought, tolerance and all that.

    • Agree. It seems like irresponsible reporting to interview a couple of experts and then disagree with everything they have to say.

  22. The trade winds are turning south-westerly along the east Pacific equator.
    If Nino peaks within a couple of months it will be perfect timing to trigger a big reactive La Nina.

  23. As far as the atmosphere goes I think the atmospheric circulation is a very big player when it comes to climate . A great example of this will be the extreme cold in the eastern half of the U.S.A over the next several days.
    The oceans I think are driven by the atmospheric circulation rather then the atmospheric circulation is driven by the oceans. The oceans in time will be responded to the prolonged minimum solar activity as the article in the above alludes to.
    In addition if the atmospheric circulation is meridional it will promote more clouds and snow cover which will promote cooling.
    A more meridional atmospheric circulation ties in quite well with prolonged minimum solar activity and a negative QBO.
    When the intensity of EUV light is low(in response to weak solar activity ) the atmospheric circulation has always tended towards a more meridional atmospheric circulation pattern in response to changes in ozone distribution and concentrations in the lower stratosphere.

  24. I want to back track some and say I think it is more of a give and take as to what drives what when it comes to the atmosphere versus oceans.
    A prime example has been and still is the warm pool of water off Western North America which has been promoting the atmosphere to ridge in the Western U.S.A and trough in the Eastern U.S.A and giving the extreme cold winter weather in that part of the country.

  25. Can anyone answer: Is the pacific in a warm of cold phase what’s happening with the Atlantic . Its like trying to get the answers out of politicians .

  26. Oh FFFFFF
    Can anyone answer: Is the pacific in a warm or cold phase and what’s happening with the Atlantic . Its like trying to get the answers out of politicians .

  27. Waiting for el Ninot, Episode 10.
    Its Halloween again, here we are waiting for the great el Ninot to rise from the pumpkin patch and shower presents on us … Vladimir, what are you doing
    I’m trying to look make our patch sincere, so that el Ninot comes to our patch and not someone else’s.
    How can it look more sincere?
    The colour gradients must be simple and uniform – not too many contrasts or wrapping colour palettes.
    Well – do what you have to. Hell, its cold.
    No its not.
    Is too.
    No – your feeling cold was just an artifact of the cluttered color scheme of the pumpkin patch. Now I’ve fixed that – so its not cold anymore – see?

  28. We are just in neutral territory for the ENSO. 0.1Cs, 0.6Cs, -0.5Cs are just normal minor variations.
    The impact on the global climate is about 10% of the Nino 3.4 index so a 0.6C El Nino is only going to impact the global climate by 0.06C, nothing to get worked up about.
    It needs to get to into the +/-1.5C category to start talking about its impact.
    I don’t see enough energy building for any type of El Nino to develop. Atmospheric conditions are also neutral (except for the SOI which follows the ENSO conditions more than it is a driver).

  29. Most of the agencies monitoring El Nino have been forecasting every month from the beginning of 2014 that an El Nino would begin in the next two months. Nothing has materialized as yet and we have completed 10 months of 2014 with no month having ONI index equaling or exceeding +0.5.
    El Niño: characterized by a positive ONI greater than or equal to +0.5ºC.
    La Niña: characterized by a negative ONI less than or equal to -0.5ºC.
    By historical standards, to be classified as a full-fledged El Niño or La Niña episode, these thresholds must be exceeded for a period of at least 5 consecutive overlapping 3-month seasons.

  30. “global warming enthusiast” works well for AGW believers. It’s similar to UFO & Alien enthusiasts.
    But for the authoritarian hierarchy and icons of AGW “Global Warming Theorists” sounds better.
    They are like those “Ancient Alien Theorists” who find alien ways to explain historical unknowns.
    On another note, how the heck does Bob Tisdale produce so much analysis and why don’t any of the government funded Global Warming Theorists produce anywhere near the amount Bob does?

  31. “The author sounds awfully enthusiastic about the thought of “a decade or more of accelerated warming.””
    Actually, forget “the thought of”. I think the more worrisome thing is that we on track for a record warm year and there is is no El Niño.

  32. “The author sounds awfully enthusiastic about the thought of “a decade or more of accelerated warming.””
    Should say: I think the more worrisome thing is that we are on track for a record warm year and there is no El Niño.
    Maybe I shouldn’t write things on the bicycle trainer…

  33. Bob, you describe the Medieval Warm Period…and its end. It was likely the result of a long period of heat transfer from a sun-fueled ocean to the atmosphere, resulting in a time of plenty. Naturally, it eventually ran out of gas. Then bad luck happened. Just when the oceans were about to refuel, a veil was spread over the equatorial band, plunging the world into a very cold season.

    • perhaps, but it is hard to see how this would work, because you cannot transfer net energy from a large cold sink to a small warm sink, without a pump of some sort.
      what would work is a slowing of the rate of overturning of the oceans. if the oceans were today to stop overturning completely, there should be no doubt that the surface would warm. And it the rate of overturning was to increase, the surface would cool.
