Hello Again, Rupert Wyndham

I always know something’s afoot (ametre ?) in Climate Change Denial Fantasy Land when Rupert Wyndham (as known as “wind em up Rupert”) writes one of his scornful, crumb-full little e-mails and sends it on to me, even if it’s only in “Carbon” copy :-

re: Odysseus felled by climate change. Royal Society report‏
from: Rupert Wyndham, rupertwyndham AT gmail DOT com
to: Brice “Boz” Osnich, bosnich AT rsc DOT anu DOT edu DOT au

“Brice : Your reference to The Royal Society triggers this. There’s an intriguing clip in the Today programme, the BBC’s flagship radio news roundup. One Roger Harrabin, a pusillanimous toad masquerading as the BBC’s “Environmental Analyst”, who alters reports under 3rd party pressure – even from the terminally pathetic such as religious propagandists, is to run a climate change series, in which is asked the question: “Has the pudding been over egged?” or words to the like effect. I’m not sure that I shall be able to summon the mental resources actually to listen to this garbage (after all, it never changes), but it’s interesting that the BBC should even be asking the question. What seems clear is that they must have been driven to it. Has the RS yet reported? Is there any chance that something might have been leaked? Interesting times! In the meantime, in the same news roundup is the story of a WW1 Italian soldier discovered in the Dolomites, a find attributed to glacier retreat – well, naturally!”

Oh dear. I do hope Roger Harrabin doesn’t feel peeved by Rupert’s description of him. Seems ungentlemanly to me.

Made up in America

If you, or anyone dear to you, is a closet Climate Change sceptic, then you quite possibly have David Koch, of Koch Industries, and his allegedly personally paid-for propaganda machine to thank.

Climate Change denial was invented in the United States of America, but has since been imported into the United Kingdom and Australia, tripping up intellects and intelligences everywhere it shows up.

It makes a person look really uneducated when they recite the mantras of Climate Change scepticism and denial. Trouble is, it’s so pervasive and seemingly anodyne when you first encounter it, that many people just fall for it hook, line and sinker.

What’s so wrong about saying “The climate has always changed” for example ? Yes, of course it has, but not like it’s changing now.

https://www.newyorker.com/reporting/2010/08/30/100830fa_fact_mayer?printable=true

“COVERT OPERATIONS : The billionaire brothers who are waging a war against Obama. : by Jane Mayer : AUGUST 30, 2010 : On May 17th, a black-tie audience at the Metropolitan Opera House applauded as a tall, jovial-looking billionaire took the stage. It was the seventieth annual spring gala of American Ballet Theatre, and David H. Koch was being celebrated for his generosity as a member of the board of trustees; he had recently donated $2.5 million toward the company’s upcoming season, and had given many millions before that. Koch received an award while flanked by two of the gala’s co-chairs, Blaine Trump, in a peach-colored gown, and Caroline Kennedy Schlossberg, in emerald green. Kennedy’s mother, Jacqueline Kennedy Onassis, had been a patron of the ballet and, coincidentally, the previous owner of a Fifth Avenue apartment that Koch had bought, in 1995, and then sold, eleven years later, for thirty-two million dollars, having found it too small.

Flogging a Dead Non-Scandal

Despite the fact that Robin McKie killed off Climategate on 1st August 2010 in his article for The Observer (thankfully, Will Hutton was away, allowing Robin McKie to venge forcefully) :-

https://www.guardian.co.uk/commentisfree/2010/aug/01/climate-change-robin-mckie

it seems that the Climate Change deniers simply cannot let go of the dead story and bury it. Benny Peiser of the adroitly named “Global Warming Policy Foundation” (suggested motto “We want policies to guarantee Climate chaos” ?), is to publish a report at the end of the month written by Andrew Montford, of Bishop Hill web log fame :-

https://www.thegwpf.org/climategate/1204-investigation-into-climategate-inquiries-announced.html

Sorry to say, but this will be a “we told you so” affair :-

1. We told you so here first – it will be roundly criticised by those who are expert in the subjects of Climate Change and environmental policy.

2. We told you so here first – it will contain a number of significant Scientific claims that will not stand up to close scrutiny.

3. We told you so here first – it will sell.

Newsnight : Complain to the BBC

I don’t expect much from it in terms of any kind of sensible, relevant reply, but here’s my two eurocents’ worth, as loaded at :-

https://www.bbc.co.uk/complaints/forms/

The BBC are undergoing a review on balance in Science reporting. They need to get Climate Change right, and that could start by one of their programme editors actually trying to understand what programmes like this do to an unprepared or semi-prepared audience.

The Newsnight audience have been left with the view that “maybe Climate Change is not so bad after all”, which is the worst take-home message they could be given.

What a Disaster (2)

By now, astute readers of the “research paper that kills off Climate Change damages” will have noticed the classic Roger Pielke Jr-ism contained within its inner sanctum rationale :-

https://journals.ametsoc.org/doi/pdf/10.1175/2010BAMS3092.1

Let’s spell it out :-

What do you get when you compare an exponentially rising trend (economic losses from Climate Change damage) with another two exponentially rising trends (human population growth and economic development), and use the last two to factor away the first ?

That’s right – no trend at all !

We Just Don’t Know

Andrew Montford (Bishop Hill) appears on BBC Newsnight, the flagship British widescreen influential TV show for those who work until super-late o’clock and want to watch something serious after having a few beers, and all he can say is “we just don’t know” to the Kirsty Warkian question of whether Climate Change is (a) happening or (b) problematic.

Come on Andrew ! It’s not “too early to say” or even “too early to call”. It’s in black and white and online. It’s called the IPCC report, and has been followed by American and European government studies, and a mountain of academic research analyses which back it up : the world is warming, the reports are that change is already significant, and the prospects are risky.

There is still something that “we just don’t know” about. We just don’t know if Andrew Montford has read the Science. If he were to put his virtual nose between some of its digital pages he might well learn a thing or two. He seems fairly intelligent. So, here’s hoping.

Oh, and by the way, will he feel he has to disguise himself if he wants to come and talk to the freethinking carbonbusters at Climate Camp ? No need, Andrew. Peace-loving people will welcome you for a vegan curry over at the RBS Royal Bank of Scotland Headquarters, no worries, mate. But can you please take off the earnest brown tweed jacket ? It makes you look so much like Nicholas Stern, love.

Rethink Fossil Fuels

We all love the inputs, but what about the outputs ?

Fossil Fuels have been providing an easy life and easy pickings for the citizens and enterprises of the industrialised world for some time.

People love their jet-fuelled lives. One man will move one kilometre from his home to a restaurant in two and a half metric tonnes of steel and glass believing he is admired for his larger-than-car-sized car. He will wear sunshades, and oil-slicked hair (if he has any) and sport a tan from his recent holiday over the ocean. A life of glory and feeling good about himself.

But what about the emissions ? What, indeed, about the environmental devastation at the places the Fossil Fuels (and metal and glass) were mined and refined and manufactured ?

What do we leave behind ?

Climate Camp : The Peoples’ Golfing Association

Oh dear. It appears that the Edinburgh Chapter of the Peoples Golfing Association, formed in 2005 ahead of the G8 Gleneagles Summit, has got the band back together at the Climate Camp, and played a round just a tad too close to the buildings of the Headquarters of the Royal Bank of Scotland :-

https://www.bbc.co.uk/news/uk-scotland-edinburgh-east-fife-11054166

“22 August 2010 : Climate change protesters arrested at RBS office : Two women have been arrested after climate change protesters attacked the Royal Bank of Scotland’s (RBS) Edinburgh headquarters on Sunday. More than 100 protesters took part in the action, which also involved an oil-like substance being thrown at the building and windows being smashed. The protest comes in response to RBS’s investment in oil industry developments around the world…Shaun Caulfield, who took part in the attempted raid, said: “RBS is one of the biggest climate criminals in the UK. People are angry that bankers are ploughing the billions that they got in the bail out into incredibly destructive fossil fuel projects around the world.” Golf balls were also apparently thrown at the building, the Press Association reported…”

I wouldn’t call it an “attack”. It was more like a good walk spoiled.

And as for “attempted raid”…well…there are plenty enough doors to sneak through, nobody needs to break anything to get inside. They probably didn’t.

Who chipped the first ball into the panes of expensive coated glass, eh ? Lady golfers or police chappies ?

Let’s Read the IPCC (2)

“Climate Change 2007: Working Group I: The Physical Science Basis : Foreword” :-

https://www.ipcc.ch/publications_and_data/ar4/wg1/en/frontmattersforeword.html

“The report confirms that our scientific understanding of the climate system and its sensitivity to greenhouse gas emissions is now richer and deeper than ever before.”

Who is meant by the ownership word “our” ?

It cannot mean the whole of humanity, since there are still a large number of people who have no idea about the Science of Climate Change, or who deny it.

I suspect that most Climate Change deniers would stop reading this report right there – as they don’t want to be included in the group of people who accept that Climate Change is real, happening and serious, too.

Notice that there’s no question that the Climate is sensitive to Greenhouse Gas Emissions accumulating in the Atmosphere. There’s no “likelihood” associated with that statement.

Where We Come From

I never met my maternal grandmother, and family history has not been stitched well enough for me to understand what kind of person she was, until today.

Sorting through some of her keepsakes with an older relative, I found a piece of lace knotting, a small irregular sampler in a larger collection of much more accurate work.

Nobody ever saw its pattern before, but I saw it, and I show it here : the Cross of St George of England on a light background juxtaposed with a Swastika on a dark background.

It is a statement from the heart. A demonstration of the overshadowing, constant, brooding threat of its time – the War with Germany.

If reflects the war being waged in the body and soul of the person who laced it – as she neared the end of her life, losing her fight against tuberculosis.

Let’s Read the IPCC (1)

If there’s one thing about Climate Change nobody could be able to disagree on, it’s that there’s a huge amount of literature on the subject.

I figure it would be impossible for any one person to have a good grounding in the totality of the Science, spanning, as it does, most of humankind’s discoveries about the physical world.

It would be hard too to have an exceptionally well-rooted understanding even of the Synthesis of the conclusions of the Intergovernmental Panel on Climate Change (IPCC) reports.

A human mind is surely not capable of remembering all the facts and figures and how everything relates. My personal forgettery is quite active in selecting what to drop after not using it for a while, and I’m sure others experience the same thing.

For example, I’m sure Dr Judith Curry, accomplished as she is in Earth Sciences, does not remember the entire field, and does not have the tools to look everything up quickly. Which is why she gives shorthand vague, answers on web logs which annoy other people so much :-

https://scienceblogs.com/stoat/2010/08/curry_jumps_the_shark.php

I reckon, though, people should give her a break for a while to let her compose herself, and get over the shock of the Anthony Watts “tribe” eating her heart out with steak knives after she published a proper piece of Science.

The Earth as Atom

Most people over the age of 35 years old will probably be able to agree with the statement that “you learn a lot of things in life, and you also forget a lot too”.

Things get replaced in your active memory as you move from phase to phase of your life, meet and lose people, as you change careers, take up new hobbies and interests.

For instance, I used to be able to speak German passably well, but this got replaced by Dutch, and now I don’t practice speaking Dutch at all, it’s faded from my skillset.

A lot of experiences cast shadows and are best totally forgotten. Others, which we consider valuable, we tend to summarise for ourselves and retain at least the outline of what we have known.

Climate Change Denial, Everywhere

Here follows an extract of a conversation I have had with members of the Claverton Energy Research Forum, which I have cut-and-paste into a more easy-to-read fashion below the fold :-

https://groups.google.co.uk/group/energy-discussion-group/browse_thread/thread/68f666ff4f69599b/59dfb3351bb432ec?q=abbess&lnk=ol&

As you can see, there are Climate Change sceptic-deniers everywhere, even in the most knowledgeable and respectable circles.

Countering Climate Change denial from so-called “sceptics” takes a lot of time and energy, and is a bump-in-the-road nuisance/irritation distraction from the main priority for human civilisation, which is how to stop being addicted to Fossil Fuels.

On Consensus

The problem with several Climate Change denier arguments is that they are “meta” arguments – philosophical arguments about how people behave, what they intend and how things are done.

One such issue that they take is with the Intergovernmental Panel on Climate Change (IPCC) “consensus” method of operation. They seem to view the IPCC consensus as “blurred lines” – their conclusion is that the IPCC’s unified interpretation of the evidence is suspect.

When the Police want to interview eye-witnesses, and when a judge wants to hear witness evidence, the standard practice is to keep the witnesses apart, so that the lines of evidence can be as independent as possible.

By contrast, in Climate Change Science, there is a certain amount of collaboration between researchers during the course of their work, so you could say that no observations are made independently. However, this should not be labelled as “malicious collusion”, although many Climate Change deniers do do that.

A similar situation exists with Climate Change policy, or rather the incredible inertia against taking the obvious first steps towards meaningful Carbon Dioxide emissions reductions.

People are too busy with their Facebook, their Twitter, their own personal financial nemeses (is that the plural of “nemesis”, really ?) to be able to form a coherent “movement”, as Bill McKibben, Al Gore and others wish us to mobilise into :-

How paranoid is Andrew Montford of Edinburgh, Scotland ? Does he have any reason to be afeard now that the Climate Camp has parked up on his doorstep ?

Don’t worry. This isn’t a threat, Andrew. It’s a invitation. When the rocket stoves have been lit and the canvas staked out, you’re invited to come and talk with real people about the realities of Climate Change instead of being cooped up with your hot laptop at home cooking up hurtful and inaccurate things to say about working Scientists and activists.

Al Gore has been telling all the young people, and well, all of us, really, to protest, in public, to make a downright law-unabiding nuisance of ourselves :-

https://thehill.com/blogs/e2-wire/677-e2-wire/114717-al-gore-calls-for-us-protests-on-climate-change-inaction

“Gore calls for major protests on government’s climate change inaction…In a post on his personal blog headlined “The Movement We Need”…”

Well, it won’t work to call people out onto the street. Most people are too busy credit-crunching, wage-slaving or favour-scraping to be able to commit to a short-term, potentially self-defeating public display of annoyance, frustration and shrill demands.

And if people do come out to the big protests, it won’t achieve much. News reports can be swept into the trash. Activists can be swept into holding facilities. Politicians can conveniently ignore anything that isn’t violent.

Drop the loud-hailers and home-made placards, I say, and do something more…focussed.

The Climate Camp want to target the Royal Bank of Scotland for financing Coal power plants and Tar Sands oil projects, which are very bad things to be doing, and smacks of huge corporate irresponsibility, considering the bank is largely owned by the British taxpayer, and I say, if you can’t make the camp (and I can’t for reasons which I shall not go into just now), do something about money in other ways instead.

What’s your money doing ? Which oppressive regimes in oil-rich countries is it supporting ? Which Fossil Fuel companies trashing your Environment do your bank support ? Why not switch your money to an ethical financial organisation ? Why don’t we all try to do this at the same time ? “Crowd-banking” could have an impact, you never know until you try.

Let’s pick, say, Monday 23rd August 2010. And let’s all spend our way out of Climageddon together on that day. Transfer your money to an ethical bank, or pledge to do so. Phone your bank and tell them you’re leaving for a sustainable bank.

Other actions possibly useful :-

1. Refuse to buy Fossil Fuels for a day.

2. Refuse to use any hot water for one day (most hot water is produced by burning Fossil Fuels). It’s summer in the Northern Hemisphere – come on – a cool shower won’t hurt you.

3. Don’t spend any money on anything that had Petroleum-based plastic or Natural Gas-based chemicals in its production – which would rule out 85% of non-food purchases, I reckon.

4. If you’re working for a company or an organisation who have anything to do with the Energy industry, make a point of asking your boss, or their boss, or the Chief Executive or something what the company/organisation intends to do about moving the whole business to Renewable Energy.

5. One short telephone call could have you moving from burning Coal for your home electricity to a Green Energy account.

This is not a riot – but it is an emergency, and the response should match the scale of the problem.

Our Climate – Not for Sale.

Judith Curry : Carbon Lockdown

Dr Judith Curry insists, quite correctly, that we should take uncertainties into account when deciding Climate Change policy.

Yet I think our respective positions probably strongly differ on which way we weight the uncertainties.

I strongly favour the Precautionary Principle, implemented Early, making it the “Early Precautionary Principle”.

One of the reasons I come down on this end of the spectrum of possible responses to uncertainties is that there are quite a spectrum of unknowns that form the pillars of those uncertainties.

After all, if we don’t know a term in an equation, how can we possibly calculate anything meaningful with any kind of confidence ?

How can anybody feel safe and secure not knowing for certain what the actual equilibrium Climate Sensitivity amounts to ? The response of the Earth’s Climate system to extra airborne Carbon Dioxide-forced temperature rise is a number that is becoming firmer, but there are error bars. Surely this points to conservatism in emissions ?

Moreover, we could be well advised to cut back on Fossil Fuel burning not just to protect the Climate, but to save the Economy. How can we pursue our normal everyday Carbon-emitting lives not knowing how much Fossil Fuel there is left in the ground that can be inexpensively mined ?

How can we know the order of magnitude of Fossil Fuels left to extract ? And how can we know what kind of impact this will have on the Climate ?

Hockey Stick : Still Sticking

Welcome to the slightly revised and updated Hockey Stick :-

https://scienceblogs.com/deltoid/2010/08/a_new_hockey_stick_mcshane_and.php

Yes, the Earth’s temperature is warming at a very fast pace. No, even though the statistical models here may be a little questionable, the graph still looks the same, more or less, to the sterling work of Michael Mann et al. (et al. = et alia = “and the others”).

Quelle surprise…pas !

(I included a little French in here because Steve McIntyre, the most infamous Global Warming septic…oops, sorry, “sceptic”…nooo, “skeptic”… is Canadian, a famously bilingual country, or rather a country with a bilingual state, but I’m not implying that “bilingual” means “speaking with forked tongue”).

The Rate of Change

I well remember the huffing and puffing over the release of James Hansen’s paper “Target Atmospheric CO2: Where Should Humanity Aim?” :-

https://www.columbia.edu/~jeh1/2008/TargetCO2_20080407.pdf

“…Decreasing CO2 was the main cause of a cooling trend that began 50 million years ago, large scale glaciation occurring when CO2 fell to 425 +/- 75 ppm…”

The sceptic-deniers laughed and scoffed and said things to the effect that clearly there’s nothing to worry about that the current concentration of Carbon Dioxide in the air is over 390 parts per million – it won’t melt the polar ice caps.

What the sceptic-deniers haven’t understood, or pretend not to have understood, is that it is a combination of factors that caused major lasting glaciation on Earth. Yes, the level of Carbon Dioxide in the air is important. But the rate of change of Carbon Dioxide in the atmosphere is a significant component.

If the levels of Carbon Dioxide in the atmosphere change rapidly, the heating or cooling effect is amplified, in effect. You have to take account of the relative change in levels of Carbon Dioxide, not just its level at any particular point in time.

The Sum of Complexity

As Dr Judith Curry has tried to communicate to me, the physical science of Climatology is full of deep complexity, with strong ranging on a number of processes.

Just to take a typical example – the Hurricane storm track in the Caribbean. Different years produce different levels of risk, and a constantly updated projection is needed as short-term relevant climatic factors shift.

But despite the likelihood of any particular Tropical Depression forming, the range of its strength and the eventual pathway, there is still a clearly identifiable track that storms take – that Stephen Schneider called “Hurricane Alley”.

This kind of “big picture” of regional and even global phenomena means that we can safely scale out from the inner workings of individual changes in air pressure, prevailing winds and humidity and take in the larger-scale, longer-term trends.
