Potty Peer in Waikato

Well, Christopher Monckton’s “Freedom Tour” totters on. Peter Griffins has given an initial summary in his blog post Monckton’s nightmare week in New Zealand. This has links to some of the press coverage – which, as we might expect with the Potty Peer, is rather humorous.

Flate-earthers-2

Percy the Astrologer and Mavis the Comely Wench representing the NZ Flat Earth Society came to support Lord Monckton’s Waikato meetings

The good Lord was in the Waikato yesterday. He “wowed” a largely passive, and I suspect largely apathetic, “crowd’ of a couple of dozen people at his  lunchtime presentation to a student forum at the Waikato University. A high point (for me) was the applause and speeches from members of the NZ Flat Earth Society, who are, apparently, the Lord’s most enthusiastic supporters.

While Monckton was challenged on some of his cherry picking he seemed to want to hide his political message about the international conspiracy which is using climate change and scientists to impose a one world government and preparing concentration camps. I thought this was meant to be the main message of his “Freedom Tour.” But he really overdid his claim that, despite his lack of a scientific education, he was well skilled in science and had the support of most scientists. There was something about classical architecture (his education is in classics) and his skill with differential equations. People from all over the world contract him as a consultant. Bloody hell, wonder he has time for all the travelling and talking tours.

He assured us that he gets on well with scientists, works well with them, gives advice to them, and is even himself publishing peer-reviewed papers. There were just one or two individuals he seemed angry with – scientists who were “controversial” and unsupported by their colleagues. Hmm.

Poor guy, though. He wouldn’t just modestly accept the flattery from Percy the Astrologer (see photo), who listed some of Mockton’s immense achievements. He felt the need to respond in detail, repeating and describing these achievements himself. This impressed one of the bystanders who commented that the man suffered from narcissism. Had to look up that word when I got home – it describes “a generalized personality trait characterized by egotism, vanity, pride, or selfishness.” Hmm, actually seems quite correct.

A very low-key forum. Students seemed not to have heard of the guy before (except a suspicious few elderly types who heckled scientists) – one student even referred to him as “that man in the suit.” Don’t know if that is just modern student apathy, or a healthy disregard of minority personalities. Perhaps these students have a fuller life than I do.

Later in the evening Monckton spoke to a meeting sponsored by the NZ Institute of International Affairs (Waikato Branch). I think their support is just local, and I wonder if their political orientation is somewhat unrepresentative.

I didn’t bother with that meeting but followed it on Twitter. It sounded rather humorous. I have put together below some of the tweets using Storify (see Potty peer in the Waikato or follow the hashtag #MoncktonLive).

Wish I had gone now!


Some of Joshua Drummond’s tweets from Monckton’s Monday Night Waikato meeting. This was sponsored by the NZ Institute of International Affairs (Waikato Branch) – I think the support was purely local.

Of course, there was the usual cherry picking and misinformation

cakeburgerJoshua Drummond@cakeburger Drought’s nothing to worry about. That’s good. I think he should tell that to Waikato farmers. They’d laugh. #MoncktonLive
cakeburger Joshua Drummond@cakeburger Antarctic glaciers aren’t retreating, therefore glaciers aren’t retreating. #MoncktonLive

Is he still claiming he is a member of the House of Lords?

cakeburger Joshua Drummond@cakeburger I read the letter from the House of Lords at him. Audience: When did you write that? #MoncktonLive

cakeburger Joshua Drummond@cakeburger That was interesting. He didn’t like being told he wasn’t a member of the House of Lords. He says he is. #MoncktonLive

cakeburger Joshua Drummond@cakeburger .@ImperatorFish When I pressed him after event he refused to give yes or no, just repeated “learned opinion is that I am” #MoncktonLive

Seems much of the audience was pretty much in awe of the Potty Peer.What does this say about the members of the NZ Institute of International Affairs (Waikato Branch)? Is this a local libertarian coven?

This final drama sounds intriguing. Would love to see a video. or perhaps a circus presentation by clowns.

What is global temperature?

When I write here about climate change you can be sure one or more trolls will pop up and tell me about the snow in the UK. Or accuse scientists of relying on this year’s New Zealand drought in their claims of climate change. It seems surprising that no matter how many times we point out the climate is not the same as weather, and global climate change is not the same as local or regional weather, some people seem to think such arguments are valid.

I have illustrated the difference before here – but here’s another example I picked up from Real Climate (see Response by Marcott et al.). The illustration is in response to the question of what is meant by global Temperature. Here’s what they say:

“Global average surface temperature is perhaps the single most representative measure of a planet’s climate since it reflects how much heat is at the planet’s surface. Local temperature changes can differ markedly from the global average. One reason for this is that heat moves around with the winds and ocean currents, warming one region while cooling another, but these regional effects might not cause a significant change in the global average temperature. A second reason is that local feedbacks, such as changes in snow or vegetation cover that affect how a region reflects or absorbs sunlight, can cause large local temperature changes that are not mirrored in the global average. We therefore cannot rely on any single location as being representative of global temperature change. This is why our study includes data from around the world.

We can illustrate this concept with temperature anomaly data based on instrumental records for the past 130 years from the National Climatic Data Center (http://www.ncdc.noaa.gov/cmb-faq/anomalies.php#anomalies). Over this time interval, an increase in the global average temperature is documented by thermometer records, rising sea levels, retreating glaciers, and increasing ocean heat content, among other indicators. Yet if we plot temperature anomaly data since 1880 at the same locations as the 73 sites used in our paleotemperature study, we see that the data are scattered and the trend is unclear. When these same 73 historical temperature records are averaged together, we see a clear warming signal that is very similar to the global average documented from many more sites (Figure 1). Averaging reduces local noise and provides a clearer perspective on global climate.”

I was wrong about Lord Monckton

I must admit I was wrong about Lord Monckton. I thought his speaking tour of New Zealand, which started on April Fools day, would be a huge yawn. Local climate scientists have learned that debating the man may be a huge plus for Monckton’s CV, but it was a negative for their own. So what interest could there be in a speaking tour where the audiences were basically fellow climate change deniers, conspiracy theorists and extreme political libertarians – all singing from the same hymn sheet.

After all, even his own publicity makes clear that his message is political, not scientific. That he is here to tell us all about the international conspiracy of greenies, fascists, communists, capitalists, imperialists and the United Nations to impose a single world government, put us in concentration camps, etc. Those horrible climate scientists are only a small part of Monckton’s international conspiracy.

Monckton-posters

But I should have learned from Monckton’s Australian tour. His antics there managed to keep his name in the public eye – and give Australians something to laugh at. He threatened climate scientists with court action and called prominent Australians Nazis!

Well, he seems set to do the same for us. He’s only been here a few days and he is threatening (“in the first instance”) a complaint to the New Zealand Press Council (yes he is not happy with the way his beliefs are reported). He expects the press Council to investigate not only a recent Herald article about his tour but also “whether the Herald has given balanced coverage to both sides of the debate on the climate, having regard not only to the present article but to its previous record of publication on the climate “science” issue.” He expects (or demands) a lot, doesn’t he?

Monckton  also promises to invite “authorities in the United Kingdom to remove the name of one of [our] universities . . .from the list of academic institutions whose degrees are recognized in Britain.” No, he is not happy with what our climate scientists tell us about their findings (or indeed the findings themselves), or what they think of his scientific credibility. So we are all going to be punished.

It’s enough to make us shiver in our boots – he must be such a powerful man. Our scientist’s degrees won’t be recognised in the UK in future.

I think we are shivering – but out of laughter, not fear.

The man is certainly good for a laugh. I look forward to more of this humour as his speaking tour, and threats against our media, scientists and educational institutes, progresses over the next few weeks.

If you want to read his letters and threats they are recorded at VISCOUNT MONCKTON’S RESPONSE TO DENIGRATORY ARTICLE IN NZ HERALD). Looks like they will also be faithfully repeated at the Climate Conversation Group’s blog (see, for example  Herald, APNZ find Monckton no easy target).

New “Hockey Stick” but same tired old denial

Ian Wishart is on his climate change conspiracy high horse again (see New global warming scandal hits climate science). His fevered imagination has managed to produce a “scandal” out of the publication of a scientific paper. Of course the scandal is based entirely on his climate change denial echo chamber. His denier mates have ripped into this paper. They are obviously very upset by it – more so than normal. It’s worth asking why?

I think the simplest answer lies with the word “Hockey Stick!” This phrase, together with reference to Dr Michael Mann, usually gets them foaming at the mouth. And it’s amazing what rubbish they can spout once so provoked.

This time they are reacting to a new “Hockey Stick” presented in a recent Science paper by Shaun A. Marcott, Jeremy D. Shakun, Peter U. Clark and Alan C. Mix. (see “A Reconstruction of Regional and Global Temperature for the Past 11,300 Years.”) The earlier research had extended back roughly 1,500 years, and suggested that the rapid temperature spike of the past century, believed to be a consequence of human activity, exceeded any warming episode during those years. This new work confirms that result while suggesting the modern warming is unique over a longer period.

The new work compiled the most meticulous reconstruction yet of global temperatures over the past 11,300 years, almost the entire Holocene. They used indicators like the distribution of microscopic, temperature-sensitive ocean creatures to determine past climate. The plots below compare these new results with those found by previous workers

Hockeystick-Marcott_Mann2008

The temperature reconstruction of Marcott 2013 (past 11,000 years) and a collection of reconstructions (past 1800 years) as presented by Mann 2008. (Credit: The two epochs of Marcott and the Wheelchair).

Wishart says the new paper “claimed to have validated the discredited “hockey stick” graph and proven that modern temperatures were the highest in four millennia.” He then goes on to use the authors’ simple acknowledgement that “The 20th century portion of our paleotemperature stack is not statistically robust” to claim their “story is rapidly unravelling” and that this is a “new global warming scandal.”

Bloody hell – is that all it takes to produce a scandal? For a scientist to point out limitations in part of their data (an area already extensively covered by other work)? What does Ian think – that every piece of scientific work must repeat in depth all the previous work? That no existing information can be used?

No of course not. He is just being dishonest. Using anything he can get hold of to weave a story discrediting honest science – and honest scientists. We have seen it all before in the lies he and his climate change denial mates promoted about Dr Michael Mann’s work – the work producing the original “Hockey Stick.”

For example, Wishart’s reference to “the discredited “hockey stick” graph” is a lie he promotes in his book “Con Air” (see  Alarmist con for my review) and is repeated ad nauseum in the climate denial echo chamber. But it is just not true. Far from being discredited this work has been validated again and again. It’s the critics of this work who have been discredited. Been caught lying.

I summarised this several years ago in my article Climate change deniers’ tawdry manipulation of “hockey sticks”. Have a look at that if you want details.

The climate change denial movement worked extremely hard to discredit the work of Michael Mann which produced the original “Hockey Stick.” Mann has described this campaign in his book The Hockey Stick and the Climate Wars: Dispatches from the Front Lines (see The truth about the hockey stick for my review of the book). Their campaign failed. This work has been discredited in one place only – the  biased mind of the committed climate change denier like Ian Wishart.

Climate contrarians/deniers are cherry picking again

Cameron Slater at Whale Oil Beef Hooked  is displaying his confusion again. He’s casting doubt on the findings of climate science by reproducing extracts of a MailOnline article about the bad snow storms in the UK (see Global Warming bites Britain in the arse, freezing weather kills thousands of pensioners). He adds his own “profound” comment with:

“The warmists still insist the planet is warming, and they want us to attempt to cool it down. Meanwhile the freezing temperatures have killed an extra 2000 pensioners.

When will the f*ckwits who think climate change making the earth cooler is a good thing start to apologise. History has shown us that civilisation flourishes in warm and ebbs away in the cold. Yet they insist on pushing us down the path of cooling the planet.”

Of course this is just cherry picking on a grand scale. Climate change deniers like Slater (and his mates at the local contrarian/denier blog Climate Conversation Group) seem to spend the New Zealand summer and autumn in the northern hemisphere, intellectually anyway. They continually comment on, and lament, snow storms and freezing pensioners in the UK, Canada or the US, while the rest of us are moaning about the local record droughts and high temperatures.

And they blatantly imagine their comments on regional weather are somehow directly relevant to global trends. Well, they aren’t – and there is plenty of data showing that. Here are recent examples from Arctic News (see Huge patches of warm air over the Arctic).

28
33

Have a look at the colour codes. Sure the UK is suffering from lower than normal temperatures (blue/purple) – but other regions suffer from higher than normal temperature (yellow/red).

Naturally Arctic News is concerned about the Arctic. The blog comments:

“Over the past month or so, huge patches with temperature anomalies of over 20 degrees Celsius have been forming over the Arctic.

The three images [above] show such patches stretch out from Svalbard to Novaya Zemlya (top), north of Eastern Siberia (middle) and over West Greenland and Baffin Bay (bottom).”

The comment further:

“Indeed, as the jet stream slows down and becomes more wavier, such patches of warm air can be expected to extend more regularly into the Arctic. The result can be a huge melt of Arctic sea ice, as well as a huge melt of snow cover in Greenland, which also dramatically lowers albedo, as occurred in 2012 and as discussed in the earlier post Greenland is melting at incredible rate.

This spells bad news for the Arctic sea ice, which may well disappear altogether this summer.”

Cameron Slater and his mates are very parochial – but during our summer/autumn months they seem to be living in a completely different hemisphere. (Some commentators suspect they actually live in a different world).

Even so, they still keep their blinkers firmly aligned.

Extreme confirmation bias in action

How’s this for an egregious example of confirmation bias. This morning the local blog Whale oil presents this graphic to “prove” his assertions that current climate science is a “hoax’ and those who accept the science are either fools or worse (see Chart of the Day – Proof of global warming).

guide_2505022cThe chart is taken from well-known climate denying journalist Christopher Booker’s Telegraph article Look at the graph to see the evidence of global warming. Trouble is, one has to do a lot of ignoring of facts to produce such charts. In fact he has taken only two data points (and drawn a vague sort of line between them). Isn’t Booker’s little chart somewhat misleading when you see what he ignores in the total data set:

compare_datasets_new

Global near-surface temperatures from 1850 to 2012 from Met Office Hadley Centre/Climatic Research Unit HadCRUT4, NASA GISS and NOAA NCDC

I discuss this sort of cherry picking in my recent post :

“There’s a lot of noise in that graph but it does sort of support the conclusion that global temperatures have increased in the last 100 years. Mind you, if you want to create a contrary impression you can easily take a short time period – say around 1950, 1960 – 1980, 1985 – 1995 – or even the last 16 years. Cherry picking is a great thing – if your aim is to support a predetermined conclusion, and avoid (or even hide) evidence to the contrary.’

I know, I’m hardly likely to change this blogger’s position. He is operating under the completely human process of confirmation denial. Will Storr, in his recently published book The Heretics describes confirmation bias this way:

“When confronted by a new fact, we first feel an instantaneous, emotional hunch. It is a raw instinct for whether the fact is right or wrong and it pulls us helplessly in the direction of an opinion. Then we look for evidence that supports our hunch. The moment we find some, we think ‘Aha!’ and happily conclude that we are, indeed, correct. The thinking then ceases.

Psychologists know this as the ‘makes sense stopping rule’. We ignore anything that runs counter to our hunch, grab for the first thing that matches, think, Yep that makes sense, and then we rest, satisfied by the peerless powers of our fantastic wisdom. Perhaps the most embarrassing aspect of confirmation bias is the fact that we mistake the process of searching for favourable evidence as a fair survey of both sides of the argument.”

You see this psychological phenomena again and again in internet articles and comments on climate change. But what is becoming clearer and clearer is that the prejudice underlying this particular confirmation bias is an extreme right-wing political position of the sort promoted by Chris Monckton and his “Agenda 21” myth.

Perhaps the fact that these extreme distortions and misrepresentation of current climate change science is becoming so obviously associated with this sort of politics is one reason more and more people are refusing to subscribe to the “climate change hoax” myth.

Greedy Lying Bastards

This film has a very apt title – Greedy Lying Bastards. It’s being released for theatres this week in the US. Wonder if we will get to see it here. Below is some information on its content.

(By the way – one of the greedy lying bastards in the poster is coming to New Zealand on a speaking tour next month. Guess who?)

GLB-MainPoster

Climate change is no longer a prediction for the future, but a startling reality of today. The U.S. Pentagon believes it to be a matter of national and international security. Yet, as the evidence of our changing climate mounts and the scientific consensus proves a human causation, there continues to be no political action to thwart the warming of our planet.

“Greedy Lying Bastards” investigates the reason behind stalled efforts to tackle climate change despite consensus in the scientific community that it is not only a reality but also a growing problem that is placing us on the brink of disaster. The film details the people and organizations casting doubt on climate science and claims that greenhouse gases are not affected by human behavior. Filmmaker and political activist Craig Rosebraugh, in association with Executive Producer Daryl Hannah, documents the impact of an industry that has continually put profits before people, waged a campaign of lies designed to thwart measures to combat climate change, used its clout to minimize infringing regulations and undermined the political process in the U.S. and abroad.

Millions are spent each year by oil and related interests to fund the think tanks, groups, scientists and politicians waging what the film deems a campaign of deceit regarding the science of climate change and its dire impact on the planet. Between 1998 and 2012, “Greedy Lying Bastards” reports ExxonMobil spent over $27 million to dispel claims of global warming. The Koch brothers, who run the conglomerate Koch Industries, also provide significant funding. From 1997 through 2012, they spent over $67 million.

A far different story about climate change is told by the residents of Kivalina, a small Alaskan island above the Arctic Circle. Over the last fifty years, winter temperatures have risen nearly seven degrees and the ice that once protected the land is not forming properly leading to increasing erosion. As one tribal administrator notes: “The debate is over, we are dealing with the realities of climate change.”

“Greedy Lying Bastards” also presents a shocking analysis of the U.S. Supreme Court decision, Citizens United. According to the film, not only did this 2010 ruling pave the way for unlimited corporate contributions to political campaigns, but additionally it highlighted the blatant corruption of the country’s highest Court and its cozy relationship with top corporate interests.

Filmed in the US, Tuvalu, Peru, England, Uganda, Kenya, Belgium, Denmark and Germany, “Greedy Lying Bastards” includes interviews with scientists, industry experts, international political delegates, and people impacted by the changing climate as well as deniers. Among them: UN Secretary General Ban Ki-Moon; Rep. Henry Waxman (CA); former EPA head Christine Todd Whitman; top U.S. climate scientists Dr. Pieter Tans (NOAA), Dr. Mark Serreze (NOAA), Dr. Kevin Trenberth (NCAR), former President of Copenhagen Climate Summit COP15 Connie Hedegaard, UN Environmental Program Executive Director Achim Steiner, leading climate science skeptics Myron Ebell, Christopher Monckton, and Jay Lehr, and victims of the 2012 wildfires and drought in the U.S.

Climate change is not simple

I have said this before – but it bears repeating Climate change is complex. And I feel the need to repeat it now because of a current myth being pushed very strongly by climate change deniers/contrarians/sceptics. The claim that “there has been no global warming for 16 years.”

If you doubt climate change is complex have a look at this global temperature record from NASA’s Goddard Institute for Space Studies.

Fig.A2

Line plot of global mean land-ocean temperature index, 1880 to present, with the base period 1951-1980. The dotted black line is the annual mean and the solid red line is the five-year mean. The green bars show uncertainty estimates. [This is an update of Fig. 1A in Hansen et al. (2006).]

Isn’t cherry picky wonderful?

There’s a lot of noise in that graph but it does sort of support the conclusion that global temperatures have increased in the last 100 years. Mind you, if you want to create a contrary impression you can easily take a short time period – say around 1950, 1960 – 1980, 1985 – 1995 – or even the last 16 years. Cherry picking is a great thing – if your aim is to support a predetermined conclusion, and avoid (or even hide) evidence to the contrary.

So we get this sort of thing being promoted by climate change deniers (thanks to Andy for this one). Didn’t someone say a little knowledge is a dangerous thing? And isn’t cherry picking a great way of restricting knowledge?

Graph-billboard

So, just to repeat myself – here’s an extract from my post Climate change is complex. It indicates some of the scientific knowledge that climate change deniers/contrarians/sceptics ignore when they cherry pick to make this silly claims.

Natural influences just can’t explain global temperature

The figure below shows the results of simulations of global temperature from 1900 to 2005. Figure a included all the natural and anthropogenic influences.  The black line is the actual measured global temperature anomaly (obtained by subtracting the average temperature for 1901 to 1950).  The individual simulations are shown as thin yellow curves. The red line is the multi-model ensemble mean (see Figure 9.5 – AR4 WGI Chapter 9: Understanding and Attributing Climate Change).

Figure b is a similar plot using simulations which consider only the natural influences on climate. The individual simulations are shown as thin blue curves. The thick blue line is the multi-model ensemble mean.

So, climate scientist have considered both natural and anthropogenic influences. And they are unable to reproduce the global temperature changes since 1970 unless anthropogenic influences are included.

That is why the IPCC has concluded that there is a high probability (>90%) that human influences are contributing to the current observed global temperature increase.

Notice also that the experts talk about probabilities. It’s a complex field and things are rarely cut and dried. We are more certain about some influences than others. And the IPCC doesn’t hide this fact – far from it. It doesn’t make sweeping claims in the way that some of their opponents do.

Knowing what we don’t know

We can see this in another figure from the report (Figure 2.20 – AR4 WGI Chapter 2: Changes in Atmospheric Constituents and in Radiative Forcing). It shows the estimated influences of several human caused effect and solar radiation since 1750. Notice the error bars. They are much bigger in some cases than others. Notice the assessment of scientific understanding for these influences. We have a high understanding for some of them and a low understanding for others.

So, climate scientists aren’t hiding anything. They are not ignoring natural effects. They are up-front about probabilities. They acknowledge that we need more information is some areas. They are behaving like professionals.

Considering there are areas where scientific understanding is low there is clearly room for debate, discussion and more research. But deniers and contrarians who take an extreme reductionist stance, misrepresent the IPCC reports and attack honest scientists doing the research are not in a position to contribute to this.

Climate change contrarians and deniers love to hate James Hansen. He’s up there alongside Al Gore, Michael Mann and Phil Jones. And of course their hatred is no more justified in Hansen’s case than it is for the others.

Others criticise Hansen for his “activism.” His willingness to warn politicians and the population in general of the dangers we face if we continue with a “business as usual” approach to fossil fuel and CO2 emissions. They suggest this could discredit his science. Scientists must always be objective and should limit their pronouncements to the scientific facts alone.

This is not an old problem for scientists – remember their activism after the first use of nuclear weapons and the beginning of the nuclear arms race. Scientists often confront ethical issues arising out of their work.

Troll training

You may have seen this before – but it’s worth repeating. We need reminding from time to time of the tactics used by those who seek to discredit science. Particularly, at the moment, climate science.

It’s a short video – but you get the picture. These people are carrying out a political campaign – they are not interested in truth or science. Their whole approach is to smear and attempt to discredit.

Remind you of anyone?

Thanks to: Americans Against the Tea Party who offer this description:

This video was filmed in Nashville TN. A group tied to the Koch Brothers associate Howie Rich trains Tea Partiers in “guerilla internet tactics.” The presenter instructs his audience to put up false book reviews, as well as give “bad ratings” to documentary films that are embarrassing to the Tea Party. This clip shows us just how twisted, and pathologically dishonest the Tea Party really is.
