Guest essay by Jonathan Abbott
Please allow me to recount the details of my personal path to CAGW scepticism. I have never previously found myself at odds with the scientific mainstream and at times it feels quite odd. Perhaps others here have similar experiences? I am curious to know how fellow-readers came to their current views. If some have gone from genuine scepticism to accepting CAGW, I would find that especially fascinating.
My own story begins at school in England in the early 80s. Between playing with Bunsen burners and iron filings, I remember being told that some scientists predicted that we would soon enter a new ice age. This sounded quite exciting but I never really thought it would happen; I was too young then to have seen any significant change in the world around me and it all seemed rather far-fetched. A nuclear war seemed far more likely. Soon enough the whole scare melted away.
I grew up into a graduate engineer with an interest in most branches of science but especially physics. I read the usual books by Sagan, Feynman and later Dawkins (whose The Ancestor’s Tale I simply can’t recommend highly enough). I also dipped into philosophy via Bertrand Russell. I like to think this reading helped build upon the basic capabilities for critical thinking my education had provided.
I suppose it was in the early 90s that I first noticed predictions of global warming and the associated dire warnings of calamities to come. Some of these emanated from the Met Office and so I knew should be treated with a pinch of salt but other sources included NASA, which I then personally still very much respected; despite the space shuttle evidently being the wrong concept poorly executed, their basic scientific expertise seemed unquestionable. In general I was looking forward to the warmer climate predicted for the UK, and assumed that the overall effects for the globe wouldn’t necessarily all be bad.
Now, being English I knew all about the vagaries of the weather, but the warnings about CAGW always seemed to be made in the most certain terms. Was it really possible to predict the climate so assuredly? The global climate must be an extremely complex system, and very chaotic. I had recently heard about financial institutions that were spending vast sums of money and picking the very best maths and programming graduates, but still were unable to predict the movements of financial markets with any confidence. Predicting changes to the climate must be at least as difficult, surely? I bet myself climate scientists weren’t being recruited with the sort of signing-on bonuses dangled by Wall Street. I also thought back to the ice age scare, which was not presented as an absolute certainty. Why the unequivocal certainty now that we would only see warming, and to dangerous levels? It all started to sound implausible.
The whole thing also seemed uncertain on the simple grounds of common sense. Could mankind really force such a fundamental change in our environment, and so quickly? I understood that ice ages could come and go with extreme rapidity, and that following the scare of my childhood, no one seriously claimed to be able to predict them. So in terms of previous natural variability, CAGW was demonstrably minor in scale. It seemed obvious that if natural variability suddenly switched to a period of cooling, there would be no CAGW no matter what the effect of mankind on the atmosphere. Even more fundamentally, how could anyone really be certain that the warming then taking place wasn’t just natural variability anyway? The reports I read assured me it wasn’t, but rarely in enough detail to allow me to decide whether I agreed with the data or not.
The other thing that really got me thinking was seeing the sort of people that would appear on television, proselyting about the coming tragedy that it would imminently become too late to prevent. Whether from charities, pressure groups or the UN, I knew I had heard their strident and political use of language, and their determination to be part of the Great Crusade to Save the World before. These were the CND campaigners, class war agitators and useful fools for communism in a new guise. I suddenly realised that after the end of the Cold War, rather than slinking off in embarrassed fashion to do something useful, they had latched onto a new cause. The suggested remedies I heard them espouse were always socialist in approach, requiring the installation of supra-national bodies, always taking a top-down approach and furiously spending other peoples’ money. They were clearly eager participants in an endless bureaucratic jamboree.
Now don’t get me wrong: a scientific theory is correct or not regardless of who supports it. But recognising the most vocal proponents of CAGW for what they were set alarm bells ringing, and made me want to investigate further. I had always been somewhat sympathetic towards Friends of the Earth but much less so towards Greenpeace, by that time obviously a front for luddite socialism and basically shamanistic in outlook. I had deep personal concerns about the environment, having seen reports of terrible industrial pollution in developing countries and the former Eastern Bloc. I had also sailed across the Atlantic twice in a small yacht, and seen for myself floating plastic debris hundreds of miles from land. (I also saw an ‘eco warrior’ yacht in Antigua, lived on by a crusading hippy and daubed with environmental slogans. It was poorly maintained and leaked far more oil into the water than any other boat present.)
So I was quite passionate about the environment, but my focus was on keeping it clean and safe for all life to live in. I wanted people to stop overfishing and manage fish stocks sensibly, I wanted agricultural land to produce the best long-term yields possible, to provide enough food without encroaching on wilderness and wild spaces. I wanted people everywhere to have clean air to breathe and water to drink. I had hoped that the CAGW crusade would somehow also lead to more urgent progress in fighting pollution, and the other environmental issues I cared about. If anything it did the reverse. Why the absolute fixation on reducing CO2 emissions, why was it taken for granted that this was the only way to proceed? Where was the public debate about the balance between prevention and mitigation? The CAGW protagonists always came up with solutions that were anti-industrial, anti-development and always, always required more public money. Where was the encouragement for inventors and entrepreneurs to discover and develop new technologies? And most of all, why oh why not spend some of the huge sums of money thrown at CO2 instead on getting effective pollution controls enacted in developing countries?
It had become quite clear to me that the BBC and similar media organisations would never even discuss whether the science underpinning CAGW was really robust. It had simply become a truism. An occasional doubting voice would be offered a sliver of airtime in the interests of supposed impartiality, but a proponent of CAGW would always be allowed the (much longer) last word. But, if NASA kept having to adjust their course calculations as the Voyager probes entered the outer reaches of the solar system (an utterly trivial problem compared to the complexities of the global climate), how could the science possibly be settled as claimed? Surely the great joy of science is in admitting ignorance, in taking a finely honed theory and sharpening it still further, or even better in realising a fundamental mistake and stepping aside onto a new path? The claimed certainty itself seemed unscientific.
Then in 2007 I saw a trailer on television for the forthcoming documentary The Great Global Warming Swindle. I watched it excitedly, for here finally were people publicly addressing the science and the data, but drawing alternative conclusions to the mainstream. There was none of the usual hand-waving and appeals to trust the experts, who magically seemed to be the only doubt-free scientists in recorded history. The backlash against the program told its own story too, being mainly outraged appeals to authority and conscience.
Having recently become a regular user of the internet, I started digging around looking for more information and so, soon after he started it, I found Warren Meyer’s excellent web site climate-skeptic.com. Oh, the joy! Here were links to data I could see and evaluate myself; here was critical dissection of reports and papers accepted elsewhere without demur. From there, I moved onto WUWT, Bishop Hill, Climate Audit and all the other sites that have become part of my daily round of the internet whenever I have access. However late to the party compared with many regulars at WUWT, I could now see fully both sides of the argument.
When the Climategate emails were released, some further scales fell from my eyes. I had hitherto assumed that most of the most prominent scientists supporting CAGW were well intentioned but wrong, akin to those opposing the theory of continental drift. I have taken part in many lengthy email exchanges concerning technically complex projects, and instantly recognised familiar methods used by those playing the political and bureaucratic game, for whom the data is infinitely malleable in order to reach a pre-determined goal. I had fought against this kind of factual distortion myself.
Now at this point, I am sure some (perhaps many?) readers are thinking, ‘Great, an inside view of how someone becomes a believer in a conspiracy theory, perhaps I’ll base a research paper on this idiot’. My response is that like most people I have at times stumbled upon the real conspiracy theory nuts lurking on the internet. But on WUWT and other CAGW-sceptic sites criticism of the position of the website founder isn’t just tolerated but often encouraged. ‘Prove us wrong! Please! It would be fascinating!’ There are many articles and views published on WUWT that I treat with suspicion, or even downright disagree with, but it is all stimulating and usually well argued. Plus, I am an experienced professional engineer and know what real science looks like, and when people are misusing it as a smokescreen. Neil Armstrong was a great man, and most certainly did land on the moon. Right or wrong, WUWT is a site that considers real scientific issues.
So I now find myself wondering where we go from here. The global climate will continue to change, as it has always done, and although I tend to expect some cooling I am pretty agnostic about it. Nature will assuredly do its own thing. The CAGW scare is in the process of burning out, but I do not expect an outright or imminent collapse. I hope to see the deliberate manipulators of data punished, but doubt very much it will ever come to that. Whatever happens next, it will undoubtedly be interesting, and stimulate much discussion and widely varying viewpoints. This is good news, because it means that we are back to doing science.
My skepticism began with the banning of refrigerants Montreal Protocol Circa 1985. It cost you all as consumers dearly at the grocery store and lined the pockets of Dupont and Allied Signal.
My skepticism has been reinforced with the liberal democrat fascist agenda to present day. The current CAGW crowd is teaming with mindless Democrats ready and willing to dictated what toilet paper you will use to wipe with.
I have since questioned every model and every law coming from the left since those days.
They cannot be trusted with power or the scientific method.

I would urge you actually to conduct research before commenting.
The warmest part of the Medieval Warm Period occurred before the phase identified as short on volcanism. Even the IPCC says that its warmest years were “between 950 and 1100”:
http://www.ipcc.ch/publications_and_data/ar4/wg1/en/ch6s6-6.html
Yet the phase of lower volcanic activity occurred from “1100 to 1250”:
http://www.global-climate-change.org.uk/2-6-3.php
I’d be interested to see your evidence for lowered volcanism during the Minoan Warm Period. There was a spectacular volcanic eruption during Minoan Civilization, but it may have happened before the perhaps poorly named Warm Period.
http://en.wikipedia.org/wiki/Minoan_eruption
Between these two naturally occurring Warm Periods of course lay the Roman WP, famous for its volcanism:
http://en.wikipedia.org/wiki/Mount_Vesuvius
I’d say as with all your other special pleadings, this canard has been blasted out of the sky.
What is even more interesting to me is that the Greenland Ice Sheet cores & other proxy data suggest that each of these warm periods was progressively cooler, ie the Minoan seems to have been warmer than the Roman, which appears to have been toastier than the Medieval, while the Modern is coolest of the four. The Little Ice Age also appears to have been colder than the Dark Ages & earlier Cool Periods.
My skepticism began while working in the Sierra Nevada studying bird populations. There was one meadow where the population suddenly collapsed and several biologists lamented that it was due to global warming and damned Big Oil. Although it is wise to think globally, all plants and animals respond locally. After examining USHCN temperature trends at Tahoe City http://cdiac.ornl.gov/cgi-bin/broker?id=048758&_PROGRAM=prog.gplot_meanclim_mon_yr2012.sas&_SERVICE=default¶m=TMAX&minyear=1893&maxyear=2012
and the rest of the SIerra Nevada, I found maximum temperatures were declining since the 1930s. I realized that it was landscape change not climate change that was the most critical element affecting wildlife. It was the degradation of the watershed that had diminished the wildlife and after restoring the watershed populations rebounded. At professional meetings I was astounded to see how many biologists blamed wildlife problems on the chimeric “global average” even though local maximum temperatures had not warmed. For those seeking funding for their research the joke in the biology department was “how can I connect my research to global warming.” It was clear that those in control of research funding had in essence been bribing scientists in to creating a “consensus”, and research and implementation for the most valuable environmental remedies such as habitat and watershed restoration were being misdirected.

The need to say the magic words “global warming” or “climate change” to win grant funding for your research is just one of the reasons why Oreskes’ study of journal articles is a tautological nonsense.

Thank you, people who have noted my father’s absence.
===============
I’m also sorry for not keeping up. Although I did note the surname, I didn’t realize you were his son.
Please add my “name” to the list of people urging him to come back.
He may have taken some nicks, but he’s vanquished quite a lot of the frauds and sub-mediocre scientists who come on here.
Another engineer here. My eyes were opened quite wide when the Integral Fast Reactor was killed, as I had close association with one person on the project and received some insight into the underhanded things that occurred. It became apparent to those involved that there are those who seek to destroy the prosperity and liberty of others and will stop at nothing to achieve that goal. Given that some of the same folks were pushing AGW as had fought and killed the IFR, it had to be bogus – the IFR addressed the very concerns raised by the warmists. It was killed precisely because it would have moved the world toward safety, liberty, and prosperity.
The Ozone Hole crap also played a part and seemed to be a warm-up for AGW. The same tactic was employed, to take a bit of science, twist it, exaggerate it, and sensationalize it, and then “save” the world from disaster by killing liberty and prosperity. No, eliminating Freon didn’t save the world and didn’t do a tremendous amount of damage, although it was a pretty big annoyance. It seems to me it was a practice run to see if such a ploy might succeed, to see if the general public was sufficiently gullible.
Kudos to Steve McIntyre for being one of the first to push back against the pseudoscience, and to Anthony and many others who have fought the valiant fight. I hold you in the highest regard.
You know… it’s like you have this best friend and you get along on so many different subjects but he/she supports a different football team. Why did you have to include this silly quote, ‘most of the most prominent scientists supporting CAGW were well intentioned but wrong, akin to those opposing the theory of continental drift…’? Continents acting like dodg’em cars on a molten conveyor belt hasn’t really sold me, nor did CAGW and I have patiently waited for that silliness to be exposed. Now, having made my thoughts clear, I welcome you as a friend but I don’t like your continental football team! 🙂
‘I have never previously found myself at odds with the scientific mainstream…’
Ever thought seriously about string theory?
‘I think in the next 5 years many more will share our journey to skepticism.’
Well, we’ll see….the problem is that during that time the Earth’s temperature could rise, for reasons completely unrelated to CO2 (or completely caused by it) …Or it could fall, or maybe even stay the same.
Here’s the thing…I’ve said this a thousand times but almost no one understands this very simple concept. Climate change has to be measured against what would have happened; not against the past. Whatever the effect of CO2, it will be superimposed on any climate change which would have occurred anyway…so for example if the temperature would have dropped two degrees but warming effect of CO2 (if such exists in the complex mixture of our atmosphere) mitigated it to a drop of only one degree or no change, then that is in effect, global warming.
That’s why in laboratory experiments, a negative control in addition to time-course is needed to prove a hypothesis.
@Steve D
I agree it is who it should be measured, bit it’s tangled up with too many other things if you’re just looking a daily/annual average temp.
I took the simple concept that co2 has to reduce nightly cooling to change our temp.
I mined daily records, took how much temps go up today, subtracted how much they’ll fall tonight, and found no co2 signal.

I thought it was the most succinct rebuttal of many online. I’m not wedded to SkS because of their activist bias, but sometimes they put out a good article. But if you don’t think they can be skeptical enough, here is an article on the Oregon Petition by The Skeptics’ Society.

“Why should I make the data available to you, when your aim is to try and find something wrong with it.”
Well that question just answers itself, doesn’t it?
Interesting comments on the subject of science and enlightenment. I was all jazzed up thinking of purchasing future waterfront. No joke. However; after checking the facts… NOT!
The other aspect of all this is the demonizing that “believers” of the AGW faith delivered upon “deniers” (an effort to collectively put holocaust deniers into the camp of AGW global warming skeptics). Further, is the fact that there is no skepticism of global warming of the last several centuries, however the skepticism is a notion that we humans are the cause, as if it were somehow evil the planet had warmed out of the “little ice age” and humanity is the cause. The witch hunt mentality of CAGW’s rhetoric and the incredible amount of funding to dominate the conversation of skeptics became a circus.
So here comes along a certain individual who with intense deliberation steps into the conversation only to continue the personal attacks rife with misconceived assumptions of what skeptics of AGW consider. It baffles any reasoned logic the 2 year old childishness rant an adult is so capable of.
As for the civil side of the conversation…cheers! …and refreshing!
Now that’s terrific news! When and where?

…here is an article on the Oregon Petition by The Skeptics’ Society.
http://www.skeptic.com/eskeptic/08-11-12
Oh, please. The so-called ‘Skeptics society’ in barry’s link has been ripped to shreds here on several occasions. In fact, that same silly article has been debunked several times. If that is the best that barry can do, it is no wonder he is foundering on the rocks of scientific debate.
That ‘Skeptics’ article was written by a psychologist, Gary Whittenberger — which bars him from even qualifying to be allowed to co-sign the OISM statement.
Whittenberger’s sour grapes come across loud and clear, as would befit a bureaucratic government drone who writes on ‘religion and psychology’ — a perfectly unscientific field for another know-nothing climate alarmist. Whittenberger’s nit-picking over things like referring to a “survey” instead of a “petition” during an interview does nothing to refute anything the OISM project has stated or accomplished. It is merely the psychologist’s pouting over the fact that the overwhelming consensus of scientific thought reflects the fact that CO2 is a completely harmless and beneficial trace gas. And barry is such an uneducated layman that he is incapable of posting a single verifiable, testable scientific fact or observation that supports his CAGW ‘Chicken Little’ belief. That is what happens when a layman like barry possesses no scientific education at all.
It is not surprising that the best barry can do is to cut and paste his appeals to authority by a non-authority such as a psychologist, since barry himself is an uneducated layman, possessing even less knowledge of the hard sciences than that of a psychologist. His opinions are simply a regurgitated scare by the relatively small clique of climate alarmists; barry gets his talking points from the same discredited alarmist blogs like SkS, and from religious psychology writers at his ‘pseudo-skeptics society’. No wonder barry has no credibility. That fits in with barry’s complete lack of any scientific or engineering education or experience.
How do you explain decreasing temperatures in the stratosphere? As a scientist, in my opinion, this is by far the strongest argument for AGW. I’ve yet to hear a good argument countering it.

Here is but one of the many explanations. Seriously, sir, as a scientist, I’m surprised that you haven’t already found the innumerable debunkings of this canard.

OTOH, how does CACCA explain the fact that the atmosphere has warmed less & later than the surface, as measured by the professional lying charlatans of GISS, NOAA & the HadCru crew of self-serving fraudsters?

How could we believe in this? really?
‘your’ friend Dan Miller (he is part of the ‘climate project’ or 1000 Al Gore Trainees that are paid) predictions of Ice caps being completely gone by about now hasn’t panned out. It has been 4 years since this video: (skip to 4 minutes in)
I loved it when he implies the last glaciation was a result of CO2 being 100 ppm CO2 less then it is today. In part 3 he claims billions of people are going to die if we do nothing about it. Then says, “climate change is invisible… ppm translates to deg C but it is just too complected… but we must convenience people because of the real threat” In Part 4 at 4:50 he explains why they are doing this (biggest economic changes in human history and we need to be part of it.)
Al Gore’s project more info on the non-paid people:
http://wattsupwiththat.com/2013/03/05/lucia-drops-some-reality-on-the-gorebots/
I couldn’t find any information on the paid trainees. The Video above says he was under copy right laws which means he was paid for the talk.
I was terrified of global warming. I had no scientific background. I went on a cruise in 2011 and attended a series of lectures by a retired RAF meteorologist. He said his last lecture might surprise us. It did. A few simple facts were displayed that undermined the whole of my terror.
He suggested a book to read and that was that.
I must admit to understanding not a great deal on the WUWT website but still like to try and enjoy the challenge..

No need to be defensive. Anthony was named so as the mods could see I was reporting on events between him and my father that I have only heard second-hand.
It is not my place to come to Anthony’s site and talk about him at the bottom of a thread where he may not notice it.
Netiquette is new to me but this seems like common courtesy.
I grew up in the late 50’s and early 60’s when ice age global cooling was becoming popular. I remember at least one teacher talking about it about 1958,, and reading about it in the press.
I never had much truck with people who believed in fads; my own brother used to follow most fads and I would avoid them. I was on a hike with a buddy at work, when he asked me what I thought about “global warming,” I said I didn’t know anything about it, but that I thought that it might be warmer. At that point, I got an awful look: It was like I had become an enemy, or had done something wrong. I didn’t think too much about it, and let it pass, but needless to say, our relationship deteriorated after that.
About two years ago, I was debating on a political forum called TheWorldWatch and made a post in the,, “When will Conservatives believe in global warming”, thread which said that I knew that government would do everything possible to take care of it. I suddenly started getting links posted for me to visit. In addition to the pop science links, there were some serious science links explaining GGW, and links to RealScience and SkepticalScience. I looked at RealScience.com, but I found that their ideas were often contradicted by other websites I found online. I looked at SkepticalScience.com, but found their approach a bit patronizing but interesting. I found the “list of scientists skeptical of global warming” page at Wikipedia and learned some interesting counter theories, from scientists like Abdusatamov and others.
Soon I was off looking at various websites, trying to put the story together in a coherent way for myself. What I discovered was that 95% of the stuff at real science was disprovable – they were basically just making facts up, or making facts fit. Needless to say, my posts at the political debate site became full of references to scientific papers showing disagreements between scientists and people who believed in global warming catastrophe.
Finally, I reached a point where I had debated enough. I started looking at skeptical sites like Wattsupwiththat, to see if there was anything I hadn’t thought of, started posting, “rejections”, of global warming horror stories in the popular press, and even changed from being a Democrat to a political independent. I currently publish papers on Philosophy and Foreign Policy, but I’m thinking about publishing on Climate Change, and looking for some live venues where I can speak and debate on Climate Change fear-mongering and how science is defeated by reporters, politicians and scientists in order to promote what are essentially Malthusian values. .
The final nail for me was the explanation of the Climategate emails by John Costella at http://www.lavoisier.com.au/articles/greenhouse-science/climate-change/climategate-emails.pdf It makes me furious that the people in these emails have not been held to account by the media, the law and the majority of other members of the science community.
A few here have mentioned Prince Charles. I think he is a right royal plonker. I wonder what his sons think of this issue?
Steve D says, July 27, 2013 at 6:03 pm:
You lay out the following premise: “Climate change has to be measured against what would have happened; not against the past. Whatever the effect of CO2, it will be superimposed on any climate change which would have occurred anyway …”
I agree wholeheartedly. And that’s why and how it’s easy to show that the 20% increase in total atmospheric CO2 content has had zero effect on global temperatures during the entire recent period of global warming (since about 1976/77).
You see, a few of us has been pointing this out for a long time now, but most if not everyone seems to either not grasp this very simple concept or they just completely ignore it for the sake of … I don’t know really, the firm belief that CO2 climate sensitivity just somehow HAS TO be significantly positive?
Global temperatures follow NINO3.4 rigorously without upward OR downward divergence since 1970, except at THREE abrupt instances: 1978/79, 1988 and 1998:
http://i1172.photobucket.com/albums/r565/Keyell/GWexplained_zps566ab681.png
These shifts are easily shown to be process-related to the ENSO phenomenon (referring to Bob Tisdale’s thorough descriptions and explanations), that is, NINO3.4 is a narrow equatorial region in the central and eastern part of the Pacific, normally representing the EASTERN part of ENSO. It misses however all that is happening in the WESTERN part of ENSO, which includes the West Pacific Warm Pool region. And also what is happening in the East Pacific outside the narrow equatorial band.
In 1978/79 the East Pacific warmed suddenly relative to NINO3.4. Before this, in 1976/77, it had warmed equally abrupt, though this time in tune with NINO3.4 – El Niño warming. At both of these instances the West Pacific did not warm. First it cooled (El Niño cooling), then it stayed flat, unresponsive. This was an East Pacific climate shift (‘The Great Pacific Climate Shift’ of 1976-79), a phase shift in the entire Pacific climate regime. And it pulled the rest of the world along with it. It is found both in the OHC and SST records and originated when the mean level of the pressure gradient between east and west in the (tropical) Pacific basin suddenly dropped in 1976 (SOI) and stayed there for about three decades. This flattened the thermocline east/west and also reduced the mean strength of the trade winds across the basin, reducing the average latent heat loss flux (evaporation) from the tropical Pacific region:
http://i1172.photobucket.com/albums/r565/Keyell/SOIvslatentampwind_zps8dcdab36.png
The next two sudden shifts were decidedly West Pacific. At these times the East Pacific did not warm. In fact, the East Pacific hasn’t warmed at all since the Great Pacific Climate Shift of 1976-79. The mean temperature level in the West Pacific, though, has gone up in two mighty steps (and not at any other times), the first established during the transition between the El Niño 1986-88 and the La Niña 1988-89 and the second during the transition between the El Niño 1997-98 and the La Niña 1998-99:
http://i1172.photobucket.com/albums/r565/Keyell/Trinn_zps234f2e4e.png
There was also an attempt during the aftermath of the El Niño 2009-10, but it has yet to materialise into a real step up.
As you can well see, there is no place or room for any CO2 warming effect in here at all. Zero. Unless you want to argue that the effect is such that it does nothing for about ten years, then all of a sudden lifts the mean temperature level with about 0.2 degrees. I would be interested to hear about the mechanism behind that …
The abrupt shifts simply are the ‘climate change which would have occurred anyway’. So where do we see the superimposed effect of increasing CO2?
