Behind the scenes of Bolt’s graphs

Many of our readers have noted on the way Andrew Bolt throws graphs into his climate change posts, without necessarily explaining anything about what the graph is purported to show. Sometimes it’s hard to figure out what they are supposed to show; sometimes they seem to display the opposite of what he is talking about. Sometimes we get links to the source; sometimes we don’t.

There’s a vigorous academic debate going on about one of the graphs Bolt made use of in a post yesterday:

In fact, says distinguished climatologist Professor Roger Pielke Sr, none of that seems true.

bolt_sealevel

To give Bolt credit, he links to one part of that debate – a post at the site of one of Bolt’s favourite climate commentary sources, Anthony Watts (and it is apparently Watts who added the “FLAT” to the original graph). Watts was reposting content from a blog post by Roger Pielke in which he alleged the RealClimate blog had spread “misinformation”. But there’s no sign of him updating his post to include the other side – RealClimate has responded with a strong and detailed rebuttal of Pielke’s claims. There’s more coverage at Deltoid as well. In essence, these sites argue that Pielke’s claim (and Watts’s even stronger assertion that the graph since 2006 is “FLAT”) is wrong in two ways – (i) such a short-term interval is not a reliable observation period for drawing conclusions about climate change, and (ii) even if it was, the trend in that period is still positive.

Of course, even if Andrew Bolt’s readers followed the link he provided in this case, they wouldn’t be exposed to the argument over methods and interpretation. It’s ironic that he claims to want open debate on these issues, and that he implies it’s those on the other side of the argument who skew their presentation of the evidence.

(NB: It’s also worth noting that in a later update to the same post, Bolt claims that the Mann “hockey stick” has been debunked.)

UPDATE: The debate continues with a new post by Pielke.

    Even then though, even if the last three years WERE flat (apparently the trend line is flattER, but not flat) it’s still pretty obvious where the trend is heading over the whole series, isn’t it?

    Not to Bolt and his pals, apparently.

    This is one of the things I find most disturbing about these folks – this ability to look straight at clear evidence – and just not see it! To see something else that simply isn’t there, but that does agree with the ideological position.

    Scary.

    umm I looked that the chart and it basically looks flat from 2006, Tobias. You sure you’re not looking at some other chart on a different website in error?
    Please take another look and then come back here and tell us it’s flat for that period.

    and (ii) even if it was, the trend in that period is still positive.

    Not if you’re using an annual moving average trendline it wouldn’t be.

    Tobias are you basically innumerate or are you relying on your readership to be.

    It all depends on the trendline one uses. A five year trendline would show a warming however a one year trendline would show its flat lined since 2006 and you actually by now be pointing down.

    Could you please correct the post and apologize for the errors.

    You don’t need to be so inaccurate as the science is on our side.

    If one draws a line from 2006 to 2008 (which is a case of cherry-picking), the line would be flat. If one draws a line from 2006 to 2008, however, one would find that the line in fact rises.

    So, how do we account for the flatness of the line from 2006 to 2008? Well, that period was a strong El Nino, a fact that climate scientists take into account, but which denialists do not.

    Tee, would you please apologize for your ignorance or your denialism? Either one will do.

    Tobias – Nice post showing the relative arguments from both sides of the debate. As for bolt and graphs I think we all know he has issues. Take for example this one:
    http://blogs.news.com.au/images/uploads/solar_thumb.jpg
    in the post: http://blogs.news.com.au/heraldsun/andrewbolt/index.php/heraldsun/comments/sun_accused/
    which shows the correlation between solar flares and temperature lagged 30 years. It clearly shows that over the last 150 years the relation has been effectively broken in comparison to records for the previous 700 years.

    Bolt clearly does not understand some of the graphs he presents. Or the consequences of them.

    I never said you misrepresented those two august scientific sites, Tob. What I did say is something altogether different.

    Let’s go through it again.

    1. is the short term trend up or down.

    2. if you fit a one year moving average, what would occur directionally?

    I assume you are supportive the two highly scientific sites you quoted, right?

    What I meant to say was: If one draws a line from 2006 to 2009, as shown in the diagram, one would find that the line slightly rises. I also should have said “La Nina” instead of “El Nino”.

    Climate scientists recognize the unusual warming effects of El Nino events and the unusual cooling effects of La Nina events. There was an unusual El Nino event in 1998, and an unusual La Nina in 2007.

    Bolt, just like his equivalents in the US, exploit public ignorance of the El Nino and La Nina events by picking points on the graph that give the impression of dropping temperatures. This enables Bolt to say two things – that from 1998 to the present, temperatures have dropped, and that from 2006 to 2008, temperatures have remained relatively flat. These statements are grossly misleading. 1998 had the highest temperatures on record, in fact two degrees above 1997 or 1999 temperatures, so by choosing 1998 levels, you can make a falling line on the graph. And by using what tee calls a “one year moving average”, one can also find a flat or falling line around the La Nina period of 2006-2007.

    Talk of “the short term trend” or “a one year moving average” is either ignorant or disingenuous. It ignores the El Nino and La Nina events, and also ignores the fact that climate scientists regard global warming as a long term trend, observable from the 1970s to the present. The one or two year cooling caused by the recent La Nina event does not negate the fact that global warming has been occurring since the 1970s.

But for a minute while I wait my turn to have my toenails clipped by your peers at the Andrew Bolt Skool for making sh!t up allow me to think hard, for you evidently lack such a capacity. If you’re so keen to “go with the science”, what part of the following is beyond your ability to understand:
    1) climate trends = 30+years of data;
    2) climate trends (up, down, level, sideways, launching into a new dimension, whatever) do not prevent or annul short-term phenomena;
    3) short-term phenomena are often called “weather”.

    So, once again for the benefit of the simple (if not simple-minded) souls visiting here, no reasonable person willing to “go with the science” could see anything in what Tobias wrote that conflicted with what the graph shows.

    tee, authors and commenters at both of the sites I linked to have stated that the regression methods they used still show a positive trend, even when restricting the data to the period since 2006. I noted this, and observed that Andrew Bolt simply throws in the graph without explanation and without indicating to his readers that its interpretation is being heavily debated at other sites. If you want to take issue with what those other sites said about the positive trend, you should take it up at those sites.

    For what it’s worth, my own position is that argument (i) that you quoted above, that the time interval from 2006 to present is too short to draw conclusions, makes argument (ii) irrelevant.

    Regression analysis shows that the trend is still positive.

    You mean like the recently discredited Rhamstorf et al 2007 paper where he used all sort of smoothing nonsense to come up with a result that best showed things have become worse since the IPCC.

    Here: He even discredits himself.

    In hindsight, the averaging period of 11 years that we used in the 2007 Science paper was too short to determine a robust climate trend. The 2-sigma error of an 11-year trend is about +/- 0.2 ºC, i.e. as large as the trend itself. Therefore, an 11-year trend is still strongly affected by interannual variability (i.e. weather).

    http://www.realclimate.org/index.php/archives/2009/06/a-warning-from-copenhagen/langswitch_lang/wp#comment-127955

    In other words his “non-linear” trendline was a crock of shit.

    And even if it was not, a couple of flat, or even regressive years, does not of itself end a multiple decade trend.

    tell that to Tobs as he’s the one who made the comment that it was within the trend.

    Come back in 2030 or so, if that trend actually does goes down, and then you can say “I told you so”.

    Why would I do that? Although 8 years a trend doesn’t make, I would have to say that the IPCC lower estimate of 2 degs or less over the next 100 years actually looks good.

    I’m not panicked about the IPCC estimates, you guys are. I actually think they’re pretty good and show benign warming and allow time to adapt.

    Until then, your complete and utter ignorance of the most basic foundations of statistics are only embarrassing yourself.

    I think you need to discuss it with Tob as he’s the one who raised the issue:

    even if it was, the trend in that period is still positive.

    Actually English is my first language, Zoot. It seems the reason you have a serious problem is that comprehension has never been your real strong point. That goes for {Juvenile name-calling removed – Toby} too.

    Here’s the thing, Zoot. {Juvenile name-calling removed – Toby}, and Tog are linking to Realclimate, which is basically nothing more than a catastrophist site. There are far better places to go for a long-range climate forecast than reading what those deadenders have to say. But yes, that’s a personal opinion.

    Without even blinking, {Juvenile name-calling removed – Toby} links to a site, which has the following to say:

    Some aspects of climate change are progressing faster than was expected a few years ago – such as rising sea levels, the increase of heat stored in the ocean and the shrinking Arctic sea ice.

    So er, short-term observations become “climate” or “weather” depending on who is doing the reporting. LOL…. So er if Realclicmate says things have got worse since the last (IPCC report), that of course is ” climate”. If someone else says things have remained stagnant with reasonable evidence too, over the same period that of course is “weather” and just noise.

    You’re truly are incoherent.

    As I said the-progressing-faster crap originally came from the since discredited Rahmstorf study.

    You can believe in catastrophes while I’ll continue to believe that the lower range estimate of the IPCC has more credibility.

    In this case the science from the IPCC is on my side while in this case you’re simply acting out fantasies.

    Tob, this also applies you to. You don’t want to stand behind what you said and avoid doing so by obfuscating.

    If you think short term weather patterns are basically noise, do you disagree with the Realclimate link then, which argues things have got worse over a short period of time…. that is since the last IPCC report came out?

    tee:

    Despite pointing it out several times you don’t seem capable of recognising that I was reporting what others have said about the sea level data, not making my own assertion, so I’m not responding to anything more you have to say about it.

    As for the UAH temperature graph you posted, I see that the monthly mean temperature at present is close to the mean for the entire measurement period (1979-2009) – which looks to be about the eighth time that has happened since 1998, although each time it only seems to have lasted a few months at most before the monthly temperature has gone above the overall mean again. If you fit a linear regression model to that data set, it looks to me like the slope would be positive, although I have no idea whether it would be statistically significant.

    Tob:

    The point of the exercise was to make you admit an obvious mistake in your assertion. Unsurprisingly you didn’t, Tob.

    Since the IPCC report there have been “studies” pointing to impending doom or to put it another way, “things have got worse”. The IPCC report came out in 2006 (I think) are those short term ” projections” more valid than those that are sceptical? If so why?

    Any argument about climate change based on data since 2006, whether it says it’s more or less of a problem than was thought in 2006, is equally flawed. But I’m not sure which specific studies you’re referring to – for instance, the first issue raised in the RealClimate link I provided is that data from 1993 to the present shows changes that are outside the interval estimate in the 1990 projections. If longer-term trends are outside (whether above or below) the range forecast by earlier efforts at modeling, that is notable.

    Tob:

    The gold standard for any current climate analysis and projection is the last IPCC report that combines the wisdom of countless scientists. Anything that projects out away from the IPCC upper limits is basically hysterical catastrophism.

    Notably you make excuses for that sort of junk science which is itself notable.

    That’s not a good look for someone suggesting other people are sceptics when all your doing is sneaking in underneath the other extremist tail of a distribution chart which of course means you would see everyone else as denialists.

Since you’re not going to bother responding to what I actually say and will instead wage an ongoing battle against some straw-man caricature of what I said, I won’t be responding to your comments any more.

    tee: It is quite obvious. Your level of debate has been quite ill founded. You ask if someone is going to comment about the graph and the supposed “flatness” in the period 2006-2008. Even though you link a reference that states that an 11 year smoothing is too narrow.

    Besides the self pwning you achieved through that comment if you take time to look at the graph and compare the 60 day trend (which is way too short to make much sense out of anyway) you will note that there was only brief peaks and a 2-3 month period when the line was above the 20 gridline. At the start of 2008 the line was below the gridline for a month or so and has not been below since.

    So are you stating you are picking out a particular date in each year to compare this flatness??? As a lot of commetators do – It hasn’t warmed since 1998 comes to mind.

    And please refrain from the name calling and personal abuse. It does not add to your argument. In fact it makes the rest of your argument look silly.

    the only conclusion is either tee is exceptionally illiterate, or s/he is a troll. either way, continually responding to the mindless ranting will only encourage more mindless ranting, and drive you mad with having to issue constant clarifications as your comments are continually twisted and turned into different meanings. tobias is right: not responding is the best approach.

    Great posts tee!
    There’s a few angles that I don’t think have been brought up yet.

    The first is how much of the graph trend is natural(therefore null) due to ;”The Sun Is More Active Now Than Over The Last 8000 Years”

    The Critical Importance of Solar Cycles – by Stephen Wilde
    http://climaterealists.com/index.php?id=3651&linkbox=true

    A real no brainer to work out that the most,if not ALL of the upward trend is of natural origin,So in fact the devation of the last 6?yrs near the top of the graph is the beginning of the next trend as the Sun goes into its next phase(maunder minimum) for 20?,30?,40?,60,or even 100 yrs WILL with absolute certainty keep that trend going.

    Any betts?

    Russian Scientists Forecast Global Cooling in 6-9 Years – August 25, 2006. Created

    Moscow – Researchers with the Russian Academy of Sciences warned Wednesday that the Earth could be headed for a 60-year cooldown, the news agency Interfax reported.

    Scientists based at the academy’s Pulkovskaya Observatory in St Petersburg, Russia, said they expected a gradual decrease in global temperatures in 2012-15, followed by a more dramatic, 60-year period of cold to come in 2055-60.

    Khabibullo Abdusamatov, chief researcher at the observatory, said the predictions were based on solar cycles, and that after the 60-year glimpse of the Ice Ages warmer weather could be expected

    Victor Manuel Velasco Herrera of the Institute of Geophysics at the University of Mexico states that “In about ten years the Earth will enter a “little ice age” which will last from 60 to 80 years and may be caused by the decrease in solar activity,” according to a report in the major Mexican newspaper Milenio Diario.

    Solar Activity Diminishes; Researchers Predict Another Ice Age – Sunspots have all but vanished in recent years.

    http://www.climatescienceinternational.org/index.php?option=com_content&view=article&id=31:vanishing-sunspots-prelude-to-global-cooling&catid=1:latest

    Excerpt: Dr. Kenneth Tapping is worried about the sun. Solar activity comes in regular cycles, but the latest one is refusing to start. Sunspots have all but vanished, and activity is suspiciously quiet. The last time this happened was 400 years ago — and it signaled a solar event known as a “Maunder Minimum,” along with the start of what we now call the “Little Ice Age.” Tapping, a solar researcher and project director for Canada’s National Research Council, says it may be happening again. Overseeing a giant radio telescope he calls a “stethoscope for the sun,” Tapping says, if the pattern doesn’t change quickly, the earth is in for some very chilly weather. […] In 2005, Russian astronomer Khabibullo Abdusamatov predicted the sun would soon peak, triggering a rapid decline in world temperatures. Only last month, the view was echoed by Dr. Oleg Sorokhtin, a fellow of the Russian Academy of Natural Sciences. who advised the world to “stock up on fur coats.” Sorokhtin, who calls man’s contribution to climate change “a drop in the bucket,” predicts the solar minimum to occur by the year 2040, with icy weather lasting till 2100 or beyond. Observational data seems to support the claims — or doesn’t contradict it, at least. […] Researcher Dr. Timothy Patterson, director of the Geoscience Center at Carleton University, shares the concern. Patterson is finding “excellent correlations” between solar fluctuations, a relationship that historically, he says doesn’t exist between CO2 and past climate changes.

    Harmful Man Induced Climate Change (Global Warming) Refuted

    “Our Global Climate Is Now Actually Now Cooling”

    “The record cold of the decades of the 1890’s, 1940’s, 1970’s, 1980’s and most recently the bitter northern hemisphere winters of 2000-2001, 2001-2002, 2002-2003 argue against the occurrence of harmful man induced climate change (global warming). Also Winter 2000-2001 and 2004-2005 in Siberian Russia, as well as Winter 2004 in Antarctica were the coldest in recorded history. And let’s not forget that January 2004 in Boston, MA was the coldest January in 111 years. Grand Forks, ND set it’s all time record low of -44 deg. below zero F, Fosston, MN also at -50 deg. below zero F and Saskatchewan, Canada saw minimum temperatures fall to -62 deg. below zero F, all in Winter 2003-2004.”

    “Satellite based systems that measure the complete land, ocean, atmosphere interface show a definite cooling trend between 1979-2004 of -0.5 deg, F.

    Radiosonde balloon launches show no temperature change between 1960-2004. Antarctica has been cooling at the rate of 1.4 deg. F per every ten years for the past 20 years. Also between 1895 and 2004 January average temperature in Florida has fallen approximately 1 deg. F. Also glaciers in Greenland and Antarctica are expanding. How can that possibly be if harmful man induced climate change (global warming) is occurring???”

    The Heartland Institute: Instant Expert’s Guide to Global Warming 1,000 Year Climate History Accurate “Thermometers” in Space – NASA

    “Unlike the surface-based temperatures, global temperature measurements of the Earth’s lower atmosphere obtained from satellites reveal no definitive warming trend over the past two decades. The slight trend that is in the data actually appears to be downward. The largest fluctuations in the satellite temperature data are not from any man-made activity, but from natural phenomena such as large volcanic eruptions from Mt. Pinatubo, and from El Ni?o. So the programs which model global warming in a computer say the temperature of the Earth’s lower atmosphere should be going up markedly, but actual measurements of the temperature of the lower atmosphere reveal no such pronounced activity.” ?

    I really don’t have time to look at all of this, but I will note that the NASA article on solar activity relies heavily on tree core analysis, of the sort which we are told is unreliable when it comes to measuring past temperatures and CO2 levels. And even then, they make the point that “Whether this effect could have provided a significant contribution to the global warming of the Earth during the last century is an open question. The researchers around Sami K. Solanki stress the fact that solar activity has remained on a roughly constant (high) level since about 1980—apart from the variations due to the 11-year cycle—while the global temperature has experienced a strong further increase during that time.

    And that’s just the only one I looked at.

    Good to see you back and taking an interest, chugg. You still don’t understand what you’re arguing about, but 10 out of 10 for enthusiasm!
