Clive Hamilton and the Global Change Institute: It’s all in your head

Dr Linda Tonk and I attended a seminar on Wednesday night- actually the inaugural seminar of the “Insight Seminar Series” organized by the UQ Global Change Institute– given by Clive Hamilton about his new book, Requiem for a Species. I found myself nodding and sometimes laughing at his description of the exact emotions that I had felt over the last few years in dealing with climate change. I was so happy to finally understand the natural human response to “death”. Of course, it starts with denial. I went through this stage as an undergraduate student whilst writing critical essays which looked at both sides of the argument. As an amateur scientist with little climate change knowledge, it was easy to be swayed after reading a handful of peer-reviewed articles for my assignments and I always liked to argue for the sake of arguing (just ask my dad).

Towards the end of my undergraduate degree I did start to see the bigger picture and I had read quite a few more papers at this stage and so I moved to the next stage, Maladaption. Maladaption is a dangerous place to be and it is probably where most of the population sits at the moment. Depression leads to the inability to do anything so I had to pull myself out of that one. Blameshifting also gets you nowhere. Even if China is building a coal power plant every week, we can’t pretend we don’t play a part when we sell them the coal. Australians can lead by example. Up until last night, I was using a part of this Maladaption phase where I would just change the subject whenever climate change was brought up. I cannot answer every question on climate change but ask me specifically about ocean acidification and corals and I can talk all day. So now I am going to move to the final phase where you control your emotions and act. I am no longer going to change the subject in these conversations (but I’ll probably still steer the conversation to my area of expertise).

The other great part of the seminar was the description of the driving force behind the climate scientists (science) and the skeptics (power, money and not the least politics). Even if you can’t understand all the climate science enough to critically dissect the arguments, it makes it easier to pick a side if you understand their motives. Climate scientists are simply presenting their work and understanding of the forces of nature. Climate skeptics, on the other hand, are ultimately annoyed that humankind cannot conquer nature and that unrestrained capitalism does not lead to sustainable living. Linda also liked this part of the seminar:

“My main concern is the widening divergence between the actual climate science and the way it is perceived by the general public. Clive Hamilton’s lecture reminded me about this topic.

As a scientist, I also get confused about all the information and misinformation that exists on climate science. All I want is to know the truth. However, on more than one occasion, my efforts to find simple non -biased answers to my questions on the web has led me straight into the hands of climate denialists propaganda. Not knowing what I’d stumbled upon I feel confident to claim I read these documents with an open mind and I am not ashamed to admit they even had me going in the wrong direction for a few sentences. Because they are good! And this is what scares me the most. It’s all about taking advantage of situations, twisting words and even blatantly lying, but it looks very professionally done!

Of course the general public is confused. On the one hand we have the climate scientists, who by nature just aren’t the best in explaining complicated things and more importantly not prepared for the rules of the game turning dirty. On the other hand there is a seemingly well-organized and professional movement who are obviously very willing to play dirty.

Now we have to rely on media to provide us with neutral information. But how can we when it all just seems to shift towards the opinions of the people with the money and the power. This is the driving force behind climate skeptics and denialists and it IS very powerful. So during last night’s seminar I was reminded by all this and once again confronted with the difficulties of getting the truth out there for the public to understand and establish a well-informed opinion. The one question I was left wondering is who will to step up to the plate and provide the missing link.

My little moment of hope sprung from the realization that by providing clarity on the psychological issues of dealing with climate change and moreover providing insight in the driving forces behind both sides (climate science and denialists) we are a step closer to uncovering true motives and therefore a step closer to understanding the real climate science.  Now all that’s left is to find papers and people that are willing to inform the public.”

Afterwards there was a great Q & A section. My favourite part from this section was discussion about the Emissions Trading Scheme and specifically the buying of carbon credits overseas (For example, by saving a rainforest in Papua New Guinea). Hamilton’s response was that this scheme has “loopholes so big that you could drive a hummer through it.” However, when looking to alternatives we need to consider the time and lobbying that will occur before a new idea reaches parliament.

There were so many important concepts brought up at this seminar. It was a great free, public event and I recommend that people attend the future seminars in this series. There is only one thing left to do now: act!

McLean et al respond and the saga heats up

Following this weeks earlier revelations of data fudging, the authors (John McLean, Chris de Freitas and Bob Carter) have responded to the debunking of their paper by Foster et al (Grant Foster, James Annan, Phil Jones, Michael Mann, Jim Renwick, Jim Salinger, Gavin Schmidt and Kevin Trenberth).  The paper was shown to be rubbed and a good example of statistical trickery nearly immediately after it was published (more on the background at Climate Shifts and Skeptical Science).

Oddly, the response was posted to the ICECAP website (click here for a direct link to the pdf) and not on either authors hompages. In fact McLean’s web site still says “The informal nature of the Foster et al critique makes it inappropriate for me to respond in detail to it here, but should the criticisms be published in the normal manner we authors will respond as appropriate”.

The document is titled Censorship at AGU: scientists denied the right of reply”. Is there a “right of reply” in academic science?  No.  There is a tradition to allow authors whose work is being criticized to respond – a tradition that was followed in this case. However, the response has to go through peer review; you don’t have any kind of right to publish in any journal.

The McLean et al response was peer-reviewed and was rejected.  Looking at it, or at least what they claim was what they submitted as a response, we can see why.  The response contains the same errors as the original article. The point of a reply isn’t simply to repeat the statements in your original paper. McLean et al largely miss the nature of the debunking by Foster et al 2010. Contrary to blog science, this is not a mere difference of opinion; the original McLean at al 2009 paper was shown to be fundamentally flawed and the analysis was likely intentionally skewed to produced the desired result. The paper should be retracted by the authors. In scientific publishing, when your work is show to be flawed (and in this case probably fraudulent), there is no automatic “right of reply”.

One thing worth noting: this whole affair is hosted on the “IceCap” blog; AKA International Climate and Environmental Change Assessment Project. Interestingly, the people listed on experts page include de Freitas and Carter, and wait, also Sallie Baliunas of the notorious (and debunked) Soon and Baliunas paper. Wasn’t de Freitas the editor of that much-maligned paper?  Sure enough. So he edited Baliunas’ paper even though they are members of the same small ideologically-oriented organization?  Isn’t that a conflict of interest?  Yup. And it is ironic given McLean et al‘s complaints about Foster et al suggesting a reviewer whose name shows up in an (illegally obtained) email of one of the authors:

In response to this request, the Foster et al. group suggested the following persons as possible reviewers for their submitted critique: Ben Santer, Dave Thompson, Dave Easterling, Tom Peterson, Neville Nicholls, and David Parker (with Tom Wigley, Tom Karl and Mike Wallace also mentioned but regarded as doubtful). Phil Jones commenting “All of them know the sorts of things to say – about our comment and the awful original, without any prompting.”

A search of the Climategate emails for each of the names suggested above shows that all six of these persons were reasonably well known to Phil Jonesm

At the end of the day, the truth of the matter largely rests with AGU and we look forward to their perspective on all this.

Despite all the song and dance about how:

Science is best progressed by open and free discussion in which all participants have equal rights of contribution.

(which is complete nonsense: all participants, don’t have equal right of contribution in any science),  McLean et al seem to have spent more time documenting how they were wronged by AGU and criticising the scientific process than they did trying to rebut and correct the errors highlighted out by Foster et al (which are still valid).

John McLean still manipulating data

Still waiting for John McLean and Bob Carter to comment on the Foster et al response published in JGR outlining exactly how they manipulated their dataset to give a false conclusion. According to McLean’s website, although the authors were well aware of the Foster response before it was published:

The informal nature of the Foster et al critique makes it inappropriate for me to respond in detail.

Right. Apparently the long delay between the original McLean et al publication and the Foster et al critique was in part due to the fact that the McClean et al were invited to respond to the critique prior to it being published in JGR, but ultimately declined.

So, while we wait for a formal response, here’s another lie from McLean’s own homepage: sea surface temperatures (SST’s) along the Great Barrier Reef are not increasing. In recent times, climate scientists have been blasted for using ultra-secret ‘tricks‘ to manipulate their data. It seems that McLean has gone one up on this in his analysis of SST’s, using statistical averaging to hide the any possible trends:

The data is in form of values for grid cells of 1 degree latitude by 1 degree longitude.  From it I extracted the data applying to the GBR Marine Park and calculated the average across the park for each month.

The GBR covers over 200,000km2, from 11’S to 24’S. By averaging surface temperatures across the entire region, McLean effectively destroys any warming trend, and presents the data as an average, with no indication of error or confidence intervals. In fact, here’s how spatially variable SST across the entire GBR Marine Park really can be (from Lough 1994):

Here it is again, this time using SST’s over the past 105 yrs (De’ath et al 2009):

Considering the seemingly obvious with latitudinal temperature gradients, why did McLean ignore spatial variability in SST’s and reach the conclusion that sea surface temperature isn’t increasing on the GBR?

These graphs make it abundantly clear that the sea surface temperature along Australia’s Great Barrier Reef are not increasing at an alarming rate. The people who say otherwise have no evidence whatsoever to support their claims. These sea temperatures might rise in future but the historical evidence suggests that this will most likely be due to the natural forces of El Nino events.

In case you missed it, here it is again: “The people who say otherwise have no evidence whatsoever to support their claims“. Really? Instead of relying on website science*, let’s go to the published literature. Using mean annual sea surface temperature (SST) records were obtained from the HadISST1 for 1° grid cells, between 1900 to 2006, De’ath et al (2009) found clear temporal trends across 2° latitudinal bands:

We’ve tried replicating the results from McLean’s website results, but the methodology is (deliberately?) vague. Considering John McLean is an employee of “Applied Science Consultants” in Victoria, Australia, we can’t bombard him with FOI requests to show us his methods and data, so it seems only fair to ask McLean to be a little more transparent in his analysis. Otherwise, the conclusion that “.. people who say otherwise have no evidence whatsoever to support their claims” seems particularly disingenuous. Should we expect a retraction on McLean’s behalf? As David Horton pointed out the other day: “This was never a scientific debate, always an ideological one, or, rather, it was always science versus ideology.”

How Bob Carter diddled his data

“We have shown that internal global climate-system variability accounts for at least 80% of the observed global climate variation over the past half-century.”

That is how Bob Carter described the implications of the paper he coauthored last year (McLean et al. 2009). But a new rebuttal to the paper (Foster et al. 2010) describes how McLean et al diddled their data to create a bogus and very strong positive relationship between the ENSO index and global atmospheric temperature. Scientists have long known that ENSO cycles, El Nino and La Nino events, can drive short-term (year to year) fluctuations in global climate and temperature.  But Foster et al McLean et al argued that there was an extremely strong relationship between the two variables, and moreover, that an increase in the ENSO index explained 80% of the observed global warming since, i.e., they argued that ENSO caused global warming.

Foster et al. 2010 is currently in press at the peer-review journal Journal of Geophysical Research but a PDF preprint can be downloaded here. Some aspects of it are technical, but most of the paper is quite readable.

The primary problem Foster et al. 2010 identified in the McLean et al. 2009 is how they transformed or filtered their data before analyzing how related the two variables were.

their [McLean et al] conclusions are seriously in error because their analysis is based on inappropriate application of filters to the data used. It is well established that ENSO accounts for much of the interannual variability in tropospheric temperatures (Trenberth et al. [2002] and references therein). By filtering they have reduced the time series studied to a narrow frequency band, thereby exagerrating what is already well-known. Consequently, their estimates are at marked variance with essentially every other study of the connection between ENSO and large-scale temperature variability, particularly with regard to the role of ENSO in any long-term warming trends, that has been carried out over the past two decades. – Foster et al

It is only because of this faulty analysis that they are able to claim such extremely high correlations. The suggestion in their conclusions that ENSO may be a major contributor to recent trends in global temperature is not supported by their analysis or any physical theory presented in that paper,especially as the analysis method itself eliminates the influence of trends on the purported correlations. – Foster et al

Here Foster et al describe the diddling, in technical terms, that led to the bogus result:

For all monthly time series (the global and tropical MSU temperature estimates from UAH and the SOI from the Australian Government Bureau of Meteorology), the analysis of MFC09 first takes 12-month moving averages of the data, then takes differences between those values which are 12 months apart. The first step filters the high-frequency variation from the time series, while the second step filters low frequency variation. The latter step is perhaps the most problematic aspect of their analysis. It approximates taking the time derivative of the smoothed series, and therefore any linear trend which may be present in the original data will be reduced to an additive constant. Since additive constants have no effect on the correlation between time series, any subsequent correlation-based analysis of the processed time series can tell us absolutely nothing about the presence or causes of trends in the original data. – Foster et al

McLean et al justify the filtering by stating:

“To remove the noise, the absolute values were replaced with derivative values based on variations. Here the derivative is the 12-month running average subtracted from the same average for data 12 months later.”

But as Foster et al point out:

taking the derivative of a time series does not remove, or even reduce, short-term noise. It has the opposite effect, amplifying the noise while attenuating the longerterm changes. Thus, the use of the differencing filter has not been justified, as it has precisely the opposite effect to that invoked by the authors. The noise due to short-term “forces” has already been reduced by the moving-average step. Yet even this noise should not have been removed if the authors truly wish to estimate how much of the total variation in GTTA is due to variations in the SOI.

In spite of the extreme distorting effect of their filter, MFC09 consistently refer to the correlations and fractions of explained variation they derive as between the SOI and tropospheric temperature, both in the abstract and the conclusions. They make no attempt to draw attention to the fact, let alone emphasize, that the reported correlations are between heavily filtered time series, or between estimated derivatives of time series. This failure causes what is essentially a mistaken result to be misinterpreted as a direct relationship between important climate variables. – Foster et al

The second problem with McLean at el is their stitching together of temperature data from two sources in their Figure 7, as a way to suggest their statistical findings are also evident in the raw data trends.  Two aspects of this are fishy.  One, they failed to correct for an offset in one of the datasets, which effectively reduced a recent observed warming trend (see Foster et al’s discussion of this just below).  Two, they effectively hid this stitching wiith vertical lines in their graphic.

In Figure 7 of MFC09, the authors plot actual GTTA (not filtered versions) against the SOI (using different axes) to illustrate the quality of the match between them. However the GTTA signal they plot is a splice of RATPAC-A data through 1979 followed by UAH TLT data since 1980. RATPAC-A data show a pronounced trend over the entire time span, which is visually evident from Figure 4 in MFC09, the temperature line rising away from the SOI line. It is especially misleading simply to append one data set to the other because there is a zero-point difference between the two. The mean values of RATPAC-A and UAH TLT data during their period of overlap differ by nearly 0.2 K, so splicing them together without compensating for this introduces an artificial 0.2-degree temperature drop at the boundary between the two. Unfortunately this is obscured by the fact that the graph is split into different panels precisely at the splicing boundary. – Foster et al

John Cook has a clear explanation of this problem too:

Another interesting feature of McLean et al 2009 is a plot of unfiltered temperature data (GTTA) against the Southern Oscillation Index (SOI) to illustrate the quality of the match between them. However the temperature signal is a splice of weather balloon data (RATPAC-A) to the end of 1979 followed by satellite data (UAH TLT) since 1980. RATPAC-A data show a pronounced warming trend from 1960 to 2008 with the temperature line rising away from the SOI line. This warming trend is obscured by substituting the weather balloon data with satellite data after 1980. It is especially misleading because the mean values of RATPAC-A and UAH TLT data during their period of overlap differ by nearly 0.2 K. Splicing them together introduces an artificial 0.2-degree temperature drop at the boundary between the two. Unfortunately, the splicing is obscured by the fact that the graph is split into different panels precisely at the splicing boundary. This splicing + graph splitting technique is an effective way to “hide the incline” of the warming trend.

McLean et al first author John McLean is an Andrew Bolt palwho often gets Bolt into trouble by sharing misinformation with him. Second author Chris de Freitas has an ethically challenged reputation as well; as an editor at Climate Research he published the notorious (and debunked) Soon and Baliunas paper.  The lead editor and several additional editors at Climate Research resigned over the de Freitas flap (see a round up of this saga here in Scientific American). And third author, Bob Carter is a skeptic media darling, frequently appearing on right wing American talk shows like the Glenn Beck show and speaking at Heartland Institute conferences.

There was already a fair amount of analysis and discussion of the mis-deeds of McLean et al. 2009 even before the Foster et al. 2010 paper was published. Many think some of the anonymous bloggers who first noticed the problems with the study, e.g., Tamino, are indeed authors on the new Foster et al rebuttal paper. Brian Bahnisch has a recent roundup here, including:

Climate scientist busted for fudging data

Nope, it isn’t Phil Jones or Michael Mann. It is Bob Carter, a co-author on McLean et al. 2009 “Influence of the Southern Oscillation on tropospheric temperature”.

Last year, Bob claimed “We have shown that internal global climate-system variability accounts for at least 80% of the observed global climate variation over the past half-century.”

Well a new paper (Foster et al. 2010) debunks these claims and shows the underlying analysis of McLean et al. 2009 to be totally erroneous. Oops.

See John Cooks technical overview here, but put simply, the authors transformed their data in a way that resulted in an erroneous conclusion. Their inappropriate treatment of their data greatly inflated the temporal relationship between ENSO (a natural cyclic phenomena) and warming of the lower atmosphere.

Basically, Bob and his mates used a few statistical tricks to smooth away the climate trend (have a look at Figure 3 and 4 in Foster and co. paper for how this works).

The Foster et al (2010) abstract states:  McLean et al. [2009] claim that the El Ni˜no/Southern Oscillation (ENSO), as represented by the Southern Oscillation Index (SOI), accounts for as much as 72% of the global tropospheric temperature anomaly (GTTA) and an even higher 81% of this anomaly in the tropics. They conclude that the SOI is a “dominant and consistent influence on mean global temperatures,” “and perhaps recent trends in global temperatures”. However, their analysis is incorrect in a number of ways, and greatly overstates the influence of ENSO on the climate system. This comment first briefly reviews what is understood about the influence of ENSO on global temperatures, then goes on to show that the analysis of MFC09 severely overestimates the correlation between temperature anomalies and the SOI by inflating the power in the 2–6 year time window while filtering out variability on longer and shorter time scales. It is only because of this faulty analysis that they are able to claim such extremely high correlations. The suggestion in their conclusions that ENSO may be a major contributor to recent trends in global temperature is not supported by their analysis or any physical theory presented in that paper, especially as the analysis method itself eliminates the influence of trends on the purported correlations.

Bob is a well-known skeptic who also happens to be a university PhD scientist at James Cook University in Townsville Australia, also home of our friend Peter Ridd.

His rightwing affiliations are outlined by sourcewatch here:

He is a member of the right-wing think tank the Institute of Public Affairs [8], and a founding member of the Australian Environment Foundation, a front group set up by the Institute of Public Affairs.

He has made countless outlandish and false claims about climate change, climate change science and the IPCC over the years, including these gems:

“atmospheric CO2 is not a primary forcing agent for temperature change”

“any cumulative human signal is so far undetectable at a global level and, if present, is buried deeply in the noise of natural variation”

If you have the time, you can peruse his impressive catalogue of denialist talks and essays here (including his appearances on the Glenn Beck show, talks at the Heartland Institute, you get the picture).

He recently penned a screed against James Hansen in which Bob related Hansen to soviet Lamarckian biologist Trofim Lysenko. (what?!) Carter argues for an investigation of climate science and scientists. Indeed. Since he is the first prominent climate scientists to be caught manipulating data to achieve a pre-determmined outcome, is it not obvious where the investigation should begin? Secondly, he also argues that the (mostly bogus and totally overblown) problems in some of the IPCC reports should result in a policy shift. Well the logic makes sense: science should in part drive the policy.  And when found to be incorrect, the policy should adapt. The same must certainly be true then of Bob’s policy prescriptions that he based on the results of his now debunked study. As Michael Tobis write, Carter made some wild policy arguments based on the McLean et al 2009 paper:

Bob Carter, one of four scientists who has recently questioned the justification for the proposed Australian emissions trading scheme, says that this paper has significant consequences for public climate policy.

“The close relationship between ENSO and global temperature, as described in the paper, leaves little room for any warming driven by human carbon dioxide emissions. The available data indicate that future global temperatures will continue to change primarily in response to ENSO cycling, volcanic activity and solar changes.”

“Our paper confirms what many scientists already know: which is that no scientific justification exists for emissions regulation, and that, irrespective of the severity of the cuts proposed, ETS (emission trading scheme) will exert no measurable effect on future climate.”

MT links to the Climate Depot story about the paper from July 2009 which includes the press release, which in turn includes these statements:

Nature not man responsible for recent global warming

Three Australasian researchers have shown that natural forces are the dominant influence on climate, in a study just published in the highly-regarded Journal of Geophysical Research. According to this study little or none of the late 20th century global warming and cooling can be attributed to human activity.

“The surge in global temperatures since 1977 can be attributed to a 1976 climate shift in the Pacific Ocean that made warming El Niño conditions more likely than they were over the previous 30 years and cooling La Niña conditions less likely” says corresponding author de Freitas.

“We have shown that internal global climate-system variability accounts for at least 80% of the observed global climate variation over the past half-century. It may even be more if the period of influence of major volcanoes can be more clearly identified and the corresponding data excluded from the analysis.”

Bob Carter, one of four scientists who has recently questioned the justification for the proposed Australian emissions trading scheme, says that this paper has significant consequences for public climate policy.

“The close relationship between ENSO and global temperature, as described in the paper, leaves little room for any warming driven by human carbon dioxide emissions. The available data indicate that future global temperatures will continue to change primarily in response to ENSO cycling, volcanic activity and solar changes.”

“Our paper confirms what many scientists already know: which is that no scientific justification exists for emissions regulation, and that, irrespective of the severity of the cuts proposed, ETS (emission trading scheme) will exert no measurable effect on future climate.”

Also see MTs analysis and related coverage (that predates the new Foster et al paper) here and the RealClimate take here (an atrocious paper…).  Tamino, not surprisingly, picked up on this error a day after the paper was published. (so why isn’t he an author on Foster et al. 2010 – or is he?)

the real reason they note such strong correlation is that their analysis method removes all temperature variation which is due to trend — which of course makes it impossible for their analysis to indicate anything whatever about the trend.

It’s certainly not true that their analysis shows “natural climate forcing associated with ENSO is a major contributor to variability and perhaps recent trends in global temperature.” It shows no such thing; their analysis removes all the effect of trends.

Bob Carter’s statement in particular, that “The close relationship between ENSO and global temperature, as described in the paper, leaves little room for any warming driven by human carbon dioxide emissions,” shows how little he understand the analysis he himself participated in. Of course, he wouldn’t be the first to fail to understand the impact of using estimated derivatives on correlation analysis.

read the rest here (warning, equations and graphs lay ahead)

The five things we want to know are:

1) Will McLean et al. retract the paper (and will Bob Carter admit fault or even discuss the errors publicly)?

2) Will the denial0sphere and the MSM give this story (a climate change scandal!) the same coverage it has recently showered on various IPCC hiccups?

3) Will there be an investigation as Bob Carter himself and so many other skeptics have insisted on over and over again, usually in response to bogus and unsubstantiated allegations.

4) Will Bob now reverse his policy positions and urge (vocally) politicians that may have been swayed by his bogus science to do the same?  After all Bob, shouldn’t the science drive the policy?

5) Will The Australian cover this pending scandal!  A scientist behaving badly!

In the CimateDepot post titled “Peer-Reviewed Study Rocks Climate Debate! ‘Nature not man responsible for recent global warming…little or none of late 20th century warming and cooling can be attributed to humans” Mark Morano (yes that Mark Morano, whom Randy Olsen describes as “arguably the loudest mouth in the climate skeptic movement with his increasingly popular website, www.climatedepot.com. He is a former field correspondent for Rush Limbaugh, helped to promote the Kerry Swift Boat Veterans story, and former spokesman for Senator James Inhofe“) makes the argument below:

Those who claim correlation using derivatives (differences) removes a linear trend miss the point. McLean et al use this method to construct Figures 5 and 6. It should be noted that detrended data was used purely to establish the time lag between the Southern Oscillation Index (SOI) and MGT in Figures 5 and 6. This time lag was then used in Figure 7 to show that close correlation between trends in temperature and changes in the Southern Oscillation Index seven months previously.
Figure 7 presents the data in its original form; namely, data that is not detrended, but with the time shift in SOI obtained from the detrended data. If an underlying trend existed, it would have shown up in Figure 7. One would see the temperature line rising away from the SOI line if, for example, rising atmospheric carbon dioxide concentrations had a significant influence. There is little or no sign of this.

Figure 4: Seven-month shifted SOI with (a) weather balloon RATPAC-A temperature data 1958–1979 and satellite UAH temperature data (b) 1980–1995. Dark line indicates SOI and light line indicates lower tropospheric temperature. Periods of volcanic activity are indicated.

Seem reasonable?  John Cook explains why it isn’t;

Another interesting feature of McLean et al 2009 is a plot of unfiltered temperature data (GTTA) against the Southern Oscillation Index (SOI) to illustrate the quality of the match between them. However the temperature signal is a splice of weather balloon data (RATPAC-A) to the end of 1979 followed by satellite data (UAH TLT) since 1980. RATPAC-A data show a pronounced warming trend from 1960 to 2008 with the temperature line rising away from the SOI line. This warming trend is obscured by substituting the weather balloon data with satellite data after 1980. It is especially misleading because the mean values of RATPAC-A and UAH TLT data during their period of overlap differ by nearly 0.2 K. Splicing them together introduces an artificial 0.2-degree temperature drop at the boundary between the two. Unfortunately, the splicing is obscured by the fact that the graph is split into different panels precisely at the splicing boundary.

A simple mistake?  A mere coincidence?

This splicing + graph splitting technique is an effective way to “hide the incline” of the warming trend.

Precisely. Time for a climate audit?

To be clear, there is no way to discern the intentions of the authors from the published manuscript.  This could all be a series of mistakes that just happened to produce a surprising result that aligned with the ideology of the authors.  The only way to possibly determine why the authors chose the method of data transformation they did, stitched together disparate data, then effectively hid that data-melding in their figures is to ask them and/or to obtain their lab notes and correspondence about the paper. This would be invasive, but is precisely the type of scrutiny the Bob Carter’s of the world continually demand.

State of the climate (Part 2): CSIRO and BOM accuse climate change sceptics of ‘smokescreen of denial’

Daily Telegraph, 15th March 2010

AUSTRALIA’S leading scientists have hit back at climate change sceptics, accusing them of creating a “smokescreen of denial”.

The CSIRO and the Bureau of Meteorology will today release a State of the Climate document, a snapshot of Australia’s climate data and trend predictions.

The apolitical science organisations have weighed into the debate as they believe Australians are not being told the correct information about temperatures, rainfall, ocean levels and changes to atmospheric conditions.

The State of the Climate report offers Australians an easy-to-understand snapshot of data.

“Modelling results show that it is extremely unlikely that the observed warming is due to natural causes alone,” it states.

“Evidence of human influence has been detected in ocean warming, sea-level rise, continental-average temperatures, temperature extremes and wind patterns.”

CSIRO chief executive Dr Megan Clark said both organisations felt it was time “to give Australians the facts and information they are looking for and to do so in a way that is very transparent and available”.

“We are seeing a real thirst for knowledge from many Australians and we are responding to that huge public demand. There is a lot of noise out there and a lot of reference to other countries and people want to know what’s happening in this country.”

Dr Clark said the CSIRO had been observing the impacts of human-induced climate change for many years and had moved on from debate about it happening to planning for the changes to come.

State of the Climate (Part 1): CSIRO and BOM release key climate document for Australia

Australia’s Bureau of Meteorology and Commonwealth Scientific and Industrial Research Organisation (CSIRO) have joined forces to produce an effective and simple snapshot of how our climate is changing. See below for a summary, or download the entire document here. As a key document released by Australia’s two lead climate science agences, this should be front page news for every newspaper around the country today.

“Storms of my grandchildren”

I read James Hanson’s first book on climate change (“Storms of my Grandchildren” ) over the Christmas break. It is a engaging book which quietly outlines the essential facts for why one of the world’s leading planetary scientists feels we are headed for planetary disaster.  Phillip Adams does an excellent job of filling up the story by interviewing James Hansen below:

O.J. and the climate change deniers: guilty as charged

This awesome essay is by Bill McKibben.  It originally appeared here and is being widely circulated. It is from his forthcoming book “Eaarth: Making a life on a tough new planet”.  I was in LA (doing my masters degree at CSUN) during the infamous OJ trials. Like everyone else around the world, I was shocked that a jury of peers could find him innocent given the overwhelming evidence against him. (and this is especially jarring given his recent quasi-confession). It was a stunning display of cognitive dissonance. The facts, more or less clearly presented, could not penetrate preconceived ideas and hardened socio-political biases. Doesn’t that pretty much sum up what is going on in the climate change “debate”?

The attack on climate science is the O.J. moment of the 21st century

by Bill McKibben

Twenty-one years ago, in 1989, I wrote what many have called the first book for a general audience on global warming. One of the more interesting reviews came from The Wall Street Journal. It was a mixed and judicious appraisal. “The subject,” the reviewer said, “is important, the notion is arresting, and Mr. McKibben argues convincingly.” And that was not an outlier: around the same time, the first president Bush announced that he planned to “fight the greenhouse effect with the White House effect.”

I doubt that’s what the Journal will say about my next book when it comes out in a few weeks, and I know that no GOP presidential contender would now dream of acknowledging that human beings are warming the planet. Sarah Palin is currently calling climate science “snake oil,” and last week the Utah legislature, in a move straight out of the King Canute playbook, passed a resolution condemning “a well organized and ongoing effort to manipulate global temperature data in order to produce a global warming outcome” on a nearly party-line vote.

And here’s what’s odd. In 1989, I could fit just about every scientific study on climate change on top of my desk. The science was still thin. If my reporting made me think it was nonetheless convincing, many scientists were not yet prepared to agree.

Now, you could fill the Superdome with climate-change research data. (You might not want to, though, since Hurricane Katrina demonstrated just how easy it was to rip holes in its roof.) Every major scientific body in the world has produced reports confirming the peril. All 15 of the warmest years on record have come in the two decades that have passed since 1989. In the meantime, the Earth’s major natural systems have all shown undeniable signs of rapid flux: melting Arctic and glacial ice, rapidly acidifying seawater, and so on.

Somehow, though, the onslaught against the science of climate change has never been stronger, and its effects, at least in the U.S., never more obvious: Fewer Americans believe humans are warming the planet. At least partly as a result, Congress feels little need to consider global-warming legislation, no less pass it; and as a result of that failure, progress toward any kind of international agreement on climate change has essentially ground to a halt.

Climate-change denial as an O.J. moment

The campaign against climate science has been enormously clever, and enormously effective. It’s worth trying to understand how they’ve done it. The best analogy, I think, is to the O.J. Simpson trial, an event that’s begun to recede into our collective memory. For those who were conscious in 1995, however, I imagine that just a few names will make it come back to life. Kato Kaelin, anyone? Lance Ito?

The Dream Team of lawyers assembled for Simpson’s defense had a problem: It was pretty clear their guy was guilty. Nicole Brown’s blood was all over his socks, and that was just the beginning.  So Johnnie Cochran, Robert Shapiro, Alan Dershowitz, F. Lee Bailey, Robert Kardashian et al. decided to attack theprocess, arguing that it put Simpson’s guilt in doubt, and doubt, of course, was all they needed. Hence, those days of cross-examination about exactly how Dennis Fung had transported blood samples, or the fact that Los Angeles detective Mark Fuhrman had used racial slurs when talking to a screenwriter in 1986.

If anything, they were actually helped by the mountain of evidence. If a haystack gets big enough, the odds only increase that there will be a few needles hidden inside. Whatever they managed to find, they made the most of: In closing arguments, for instance, Cochran compared Fuhrman to Adolf Hitler and called him “a genocidal racist, a perjurer, America’s worst nightmare, and the personification of evil.” His only real audience was the jury, many of whom had good reason to dislike the Los Angeles Police Department, but the team managed to instill considerable doubt in lots of Americans tuning in on TV as well. That’s what happens when you spend week after week dwelling on the cracks in a case, no matter how small they may be.

Similarly, the immense pile of evidence now proving the science of global warming beyond any reasonable doubt is in some ways a great boon for those who would like, for a variety of reasons, to deny that the biggest problem we’ve ever faced is actually a problem at all. If you have a three-page report, it won’t be overwhelming and it’s unlikely to have many mistakes. Three thousand pages (the length of the latest report of the Intergovernmental Panel on Climate Change)? That pretty much guarantees you’ll get something wrong.

Indeed, the IPCC managed to include, among other glitches, a spurious date for the day when Himalayan glaciers would disappear. It won’t happen by 2035, as the report indicated — a fact that has now been spread so widely across the Internet that it’s more or less obliterated another, undeniable piece of evidence: Virtually every glacier on the planet is, in fact, busily melting.

Similarly, if you managed to hack 3,000 emails from some scientist’s account, you might well find a few that showed them behaving badly, or at least talking about doing so. This is the so-called “Climategate” scandal from an English research center last fall. The English scientist Phil Jones has been placed on leave while his university decides if he should be punished for, among other things, not complying with Freedom of Information Act requests.

Call him the Mark Fuhrman of climate science; attack him often enough and maybe people will ignore the inconvenient mountain of evidence about climate change that the world’s scientific researchers have, in fact, compiled. Indeed, you can make almost exactly the same kind of fuss Johnnie Cochran made — that’s what Rep. James Sensenbrenner (R-Wis.) did, insisting the emails proved “scientific fascism,” and the climate skeptic Christopher Monckton called his opponents “Hitler youth.” Such language filters down. I’m now used to a daily diet of angry email, often with subject lines like the one that arrived yesterday: “Nazi Moron Scumbag.”

If you’re smart, you can also take advantage of lucky breaks that cross your path. Say a record set of snowstorms hit Washington, D.C.  It won’t even matter that such a record is just the kind of thing scientists have been predicting, given the extra water vapor global warming is adding to the atmosphere. It’s enough that it’s super-snowy in what everyone swore was a warming world.

For a gifted political operative like, say, Marc Morano, who runs the Climate Depot website, the massive snowfalls this winter became the grist for a hundred posts poking fun at the very idea that anyone could still possibly believe in, you know, physics. Morano, who really is good, posted a link to a live webcam so readers could watch snow coming down; his former boss, Sen. James Inhofe (R-Okla.), had his grandchildren build an igloo on the Capitol grounds, with a sign that read: “Al Gore’s New Home.” These are the things that stick in people’s heads. If the winter glove won’t fit, you must acquit.

Why we don’t want to believe in climate change

The climate deniers come with a few built-in advantages. Thanks to ExxonMobil and others with a vested interest in debunking climate-change research, their “think tanks” have plenty of money, none of which gets wasted doing actual research to disprove climate change. It’s also useful for a movement to have its own TV network, Fox, though even more crucial to the denial movement are a few right-wing British tabloids that validate each new “scandal” and put it into media play.

That these guys are geniuses at working the media was proved this February when even The New York Times ran a front page story, “Skeptics Find Fault With U.N. Climate Panel,” which recycled most of the accusations of the past few months. What made it such a glorious testament to their success was the chief source cited by the Times: one Christopher Monckton, or Lord Monckton as he prefers to be called since he is some kind of British viscount.  He is also identified as a “former advisor to Margaret Thatcher,” and he did write a piece for the American Spectator during her term as prime minister offering his prescriptions for “the only way to stop AIDS”:

… screen the entire population regularly and … quarantine all carriers of the disease for life. Every member of the population should be blood-tested every month … all those found to be infected with the virus, even if only as carriers, should be isolated compulsorily, immediately, and permanently.He speaks with equal gusto and good sense on matters climatic — and now from above the fold in the paper of record.

Access to money and the media is not the only, or even the main, reason for the success of the climate deniers, though. They’re not actually spending all that much cash and they’ve got legions of eager volunteers doing much of the internet lobbying entirely for free. Their success can be credited significantly to the way they tap into the main currents of our politics of the moment with far more savvy and power than most environmentalists can muster. They’ve understood the popular rage at elites. They’ve grasped the widespread feelings of powerlessness in the U.S., and the widespread suspicion that we’re being ripped off by mysterious forces beyond our control.

Some of that is, of course, purely partisan. The columnist David Brooks, for instance, recently said: “On the one hand, I totally accept the scientific authorities who say that global warming is real and it is manmade. On the other hand, I feel a frisson of pleasure when I come across evidence that contradicts the models … [in part] because I relish any fact that might make Al Gore look silly.” But the passion with which people attack Gore more often seems focused on the charge that he’s making large sums of money from green investments, and that the whole idea is little more than a scam designed to enrich everyone involved. This may be wrong — Gore has testified under oath that he donates his green profits to the cause — and scientists are not getting rich researching climate change (constant blog comments to the contrary), but it resonates with lots of people. I get many emails a day on the same theme: “The game is up. We’re on to you.”

When I say it resonates with lots of people, I mean lots of people. O.J.’s lawyers had to convince a jury made up mostly of black women from central city L.A., five of whom reported that they or their families had had “negative experiences” with the police. For them, it was a reasonably easy sell. When it comes to global warming, we’re pretty much all easy sells because we live the life that produces the carbon dioxide that’s at the heart of the crisis, and because we like that life.

Very few people really want to change in any meaningful way, and given half a chance to think they don’t need to, they’ll take it. Especially when it sounds expensive, and especially when the economy stinks.Here’s David Harsanyi, a columnist for The Denver Post: “If they’re going to ask a nation — a world — to fundamentally alter its economy and ask citizens to alter their lifestyles, the believers’ credibility and evidence had better be unassailable.”

“Unassailable” sets the bar impossibly high when there is a dedicated corps of assailants out there hard at work. It is true that those of us who want to see some national and international effort to fight global warming need to keep making the case that the science is strong. That’s starting to happen.  There are new websites and iPhone apps to provide clear and powerful answers to the skeptic trash-talking, and strangely enough, the denier effort may, in some ways, be making the case itself: If you go over the multi-volume IPCC report with a fine-tooth comb and come up with three or four lousy citations, that’s pretty strong testimony to its essential accuracy.

Clearly, however, the antiseptic attempt to hide behind the magisterium of Science in an effort to avoid the rough-and-tumble of Politics is a mistake. It’s a mistake because science can be — and, in fact, should be — infinitely argued about. Science is, in fact, nothing but an ongoing argument, which is one reason why it sounds so disingenuous to most people when someone insists that the science is “settled.” That’s especially true of people who have been told at various times in their lives that some food is good for you, only to be told later that it might increase your likelihood of dying.

Why data isn’t enough

I work at Middlebury College, a topflight liberal arts school, so I’m surrounded by people who argue constantly. It’s fun. One of the better skeptical takes on global warming that I know about is a weekly radio broadcast on our campus radio station run by a pair of undergraduates. They’re skeptics, but not cynics. Anyone who works seriously on the science soon realizes that we know more than enough to start taking action, but less than we someday will. There will always be controversy over exactly what we can now say with any certainty. That’s life on the cutting edge. I certainly don’t turn my back on the research — we’ve spent the last two years at 350.org building what Foreign Policy called “the largest ever coordinated global rally” around a previously obscure data point, the amount of atmospheric carbon that scientists say is safe, measured in parts per million.

But it’s a mistake to concentrate solely on the science for another reason. Science may be what we know about the world, but politics is how we feel about the world. And feelings count at least as much as knowledge. Especially when those feelings are valid. People are getting ripped off. They are powerless against large forces that are, at the moment, beyond their control. Anger is justified.

So let’s figure out how to talk about it. Let’s look at ExxonMobil, which each of the last three years has made more money than any company in the history of money. Its business model involves using the atmosphere as an open sewer for the carbon dioxide that is the inevitable byproduct of the fossil fuel it sells. And yet we let it do this for free. It doesn’t pay a red cent for potentially wrecking our world.

Right now, there’s a bill in the Congress — cap-and-dividend, it’s called — that would charge Exxon for that right, and send a check to everyone in the country every month. Yes, the company would pass on the charge at the pump, but 80 percent of Americans (all except the top-income energy hogs) would still make money off the deal. That represents good science, because it starts to send a signal that we should park that SUV, but it’s also good politics.

By the way, if you think there’s a scam underway, you’re right — and to figure it out just track the money going in campaign contributions to the politicians doing the bidding of the energy companies. Inhofe, the igloo guy? Over a million dollars from energy and utility companies and executives in the last two election cycles. You think Al Gore is going to make money from green energy? Check out what you get for running an oil company.

Worried that someone is going to wreck your future? You’re right about that, too. Right now, China is gearing up to dominate the green energy market. They’re making the investments that mean future windmills and solar panels, even ones installed in this country, will be likely to arrive from factories in Chenzhou, not Chicago.

Coal companies have already eliminated most good mining jobs, simply by automating them in the search for ever higher profits. Now, they’re using their political power to make sure that miners’ kids won’t get to build wind turbines instead. Everyone should be mighty pissed — just not at climate-change scientists.

But keep in mind as well that fear and rage aren’t the only feelings around. They’re powerful feelings, to be sure, but they’re not all we feel. And they are not us at our best.

There’s also love, a force that has often helped motivate large-scale change, and one that cynics in particular have little power to rouse. Love for poor people around the world, for instance. If you think it’s not real, you haven’t been to church recently, especially evangelical churches across the country. People who take the Gospel seriously also take seriously indeed the injunction to feed the hungry and shelter the homeless.

It’s becoming patently obvious that nothing challenges that goal quite like the rising seas and spreading deserts of climate change. That’s why religious environmentalism is one of the most effective emerging parts of the global warming movement; that’s why we were able to get thousands of churches ringing their bells 350 times last October to signify what scientists say is the safe level of CO2 in the atmosphere; that’s why Bartholomew, patriarch of the Orthodox church and leader of 400 million eastern Christians, said, “Global warming is a sin and 350 is an act of redemption.”

There’s also the deep love for creation, for the natural world. We were born to be in contact with the world around us and, though much of modernity is designed to insulate us from nature, it doesn’t really work. Any time the natural world breaks through — a sunset, an hour in the garden — we’re suddenly vulnerable to the realization that we care about things beyond ourselves. That’s why, for instance, the Boy Scouts and the Girl Scouts are so important: Get someone out in the woods at an impressionable age and you’ve accomplished something powerful. That’s why art and music need to be part of the story, right alongside bar graphs and pie charts. When we campaign about climate change at 350.org, we make sure to do it in the most beautiful places we know, the iconic spots that conjure up people’s connection to their history, their identity, their hope.

The great irony is that the climate skeptics have prospered by insisting that their opponents are radicals. In fact, those who work to prevent global warming are deeply conservative, insistent that we should leave the world in something like the shape we found it. We want our kids to know the world we knew. Here’s the definition of radical: doubling the carbon content of the atmosphere because you’re not completely convinced it will be a disaster. We want to remove every possible doubt before we convict in the courtroom, because an innocent man in a jail cell is a scandal, but outside of it we should act more conservatively.

In the long run, the climate deniers will lose; they’ll be a footnote to history. (Hey, even O.J. is finally in jail.) But they’ll lose because we’ll all lose, because by delaying action, they will have helped prevent us from taking the steps we need to take while there’s still time. If we’re going to make real change while it matters, it’s important to remember that their skepticism isn’t the root of the problem. It simply plays on our deep-seated resistance to change. That’s what gives the climate cynics ground to operate. That’s what we need to overcome, and at bottom that’s a battle as much about courage and hope as about data.
