Ignore the Fake Climate Debate

IMG_20200119_164755 Ignore the Fake Climate Debate says [Ted] Nordhaus. And he's right1. The second half of the sub-head of The deniers and alarmists may make headlines, but behind the scenes, an expert consensus is taking shape on how to respond to global warming is perhaps a bit more dubious. That almost everything you see in the Meeja, Twatter and indeed blogs is about the fake debate is all too true. That doesn't mean it's actually wrong, just not the real debate. But there's so much drivel in the public eye that anyone trying to be responsive ends up mostly talking about drivel, even if they're not actually talking drivel. I feel this to be so uncontroversial that I can't be bothered to demonstrate it; do tell me if you disagree.

Father2 Ted picks Greta Thunberg and Donald Trump as his archetypes of Alarmists and Deniers, and that seems reasonable enough. DT as denier seems uncontroversial so again I won't bother demonstrate; GT as alarmist may ruffle a few feathers but At Davos we will tell world leaders to abandon the fossil fuel economy? may do. And he says:
In the real climate debate, no one denies the relationship between human emissions of greenhouse gases and a warming climate. Instead, the disagreement comes down to different views of climate risk in the face of multiple, cascading uncertainties. On one side of the debate are optimists, who believe that, with improving technology and greater affluence, our societies will prove quite adaptable to a changing climate. On the other side are pessimists, who are more concerned about the risks associated with rapid, large-scale and poorly understood transformations of the climate system. But most pessimists do not believe that runaway climate change or a hothouse earth are plausible scenarios, much less that human extinction is imminent. And most optimists recognize a need for policies to address climate change, even if they don’t support the radical measures that Ms. Thunberg and others have demanded. In the fake climate debate, both sides agree that economic growth and reduced emissions vary inversely; it’s a zero-sum game. In the real debate, the relationship is much more complicated. Long-term economic growth is associated with both rising per capita energy consumption and slower population growth.
And so on. It wasn't quite all sensible; I don't quote everything. But for an Op-Ed in the WSJ it seems pretty good. He never really justifies "expert consensus is taking shape on how to respond to global warming"; the closest is somewhat different:
All of this suggests that continuing political, economic and technological modernization, not a radical remaking of society, is the key to both slowing climate change and adapting to it. And while the progress we’ve made has mostly not been due to climate policies that would cap, regulate or tax emissions, it has required government action.
That's probably his consensus; and it may be right. Somewhat like Brexit: we appear almost doomed to a rather pointless Brexit, when just remain would be more efficient. We could deal with GW more efficiently, but are doomed to muddle through.

End of the line for photogenic teens?

DSC_6095 Appeals Court Dismisses Landmark Youth Climate Lawsuit Vs. U.S. Government says ClimateLiabilityNews, or if you prefer the Dork Side, Climate Kidz case scuttled by 9th Circuit Court. And the reasons appear to be much as before. This is Juliana, if you haven't been paying attention; I say that so that Search will find it when I need it.

Read the judgement here; although for nominally sober judges is reads like they've been at the sherry: A substantial evidentiary record documents that the federal government has long promoted fossil fuel use despite knowing that it can cause catastrophic climate change, and that failure to change existing policy may hasten an environmental apocalypse. Probably, they're feeling a bit guilty about dismissing it, so have thrown them a bone1.

According to Vox, Andrea Rodgers, a senior attorney at Our Children’s Trust, the nonprofit backing the youth who filed the lawsuit, described the decision in an email as “unprecedented and contrary to American principles of justice.” This is of course a lie. It has several precedents, most obviously Alsup, as my previous post noted. Have these people no shame?2. And the reasonning here is similar: the panel held that it was beyond the power of an Article III court to order, design, supervise, or implement the plaintiffs’ requested remedial plan where any effective plan would necessarily require a host of complex policy decisions entrusted to the wisdom and discretion of the executive and legislative branches. In case you're tempted to argue "but that leaves us no recourse!" I point out that you are wrong: the forum for resolution of such disputes is the political process; if you reply "but we get nowhere with that!" then the reply is: well, yes, indeed. So, you need to think about why very carefully, rather than go forum-shopping.

The judgement is weak scientifically and factually; I'm actually rather surprised at some elementary mistakes they make; just possibly, they are repeated the Juliana errors. But  in the 1990s, the EPA implored the government to act before it was too late. Nonetheless, by 2014, U.S. fossil fuel emissions had climbed to 5.4 billion metric tons, up substantially from 1965. This growth shows no signs of abating is drivel3.

So what of the plaintiffs claim that the government has violated their constitutional rights, including a claimed right under the Due Process Clause of the Fifth Amendment to a “climate system capable of sustaining human life.”? First, allow me to note that previous reasonning in the chain (particularised injury, and causation) that the court accepts seems weak to me; I'd expect that to get scrutinised more carefully if it goes to appeal. Then, we note the court's Reasonable jurists can disagree about whether the asserted constitutional right exists. Ah, but they don't decide it, because they don't need to: In analyzing redressability, however, we assume its existence and then go on to find lack of standing. So, the "right" will have to wait for it's day in court.

Wittily, one reason for the court deciding not to act is the plaintiffs’ experts make plain that reducing the global consequences of climate change demands much more than cessation of the government’s promotion of fossil fuels. Rather, these experts opine that such a result calls for no less than a fundamental transformation of this country’s energy system, if not that of the industrialized world, and much more text around the same ideas5.


1. Or, as they put it, "The plaintiffs have compiled an extensive record, which at this stage in the litigation we take in the light most favorable to their claims". So, even taking all their claims favourably, they still don't win.

2. Don't answer that.

3. Note that although it's drivel, it seems to be quite easy to pick up the wrong stats: per person, per $ of GDP, and just the electricity sector are the easiest stats to run across. Also "fossil fuel emissions" is an odd phrase; I presume they mean "CO2 from fossil fuels" or somesuch.

4. But again, There is at least a genuine factual dispute as to whether those policies were a “substantial factor” in causing the plaintiffs’ injuries suggests the court leaning towards the plaintiffs in order to make the dismissal.

5. And as if designed to wind up Progressives, another prong in their argument is analogy with Rucho v. Common Cause. You can tell the Dork Side is crap and can't read, because they don't even mention that.

Citing Climate Change, BlackRock Will Start Moving Away from Fossil Fuels

81791977_1362043940658589_4321250782159568896_n Says the NYer (arch). But screw that - which wasn't what BR said, anyway - instead of their interpretation let's just read the source, A Fundamental Reshaping of Finance, by Larry Fink, Chairman and Chief Executive Officer. It's addressed to CEOs; there's also a letter to clients.
As an asset manager, BlackRock invests on behalf of others... to people in dozens of countries trying to finance long-term goals like retirement. And we have a deep responsibility... to promote long-term value. Climate change has become a defining factor in companies’ long-term prospects... a risk that markets to date have been slower to reflect. But awareness is rapidly changing, and I believe we are on the edge of a fundamental reshaping of finance. The evidence on climate risk is compelling investors to reassess core assumptions about modern finance. Research from a wide range of organizations – including the UN’s Intergovernmental Panel on Climate Change, the BlackRock Investment Institute, and many others, including new studies from McKinsey on the socioeconomic implications of physical climate risk – is deepening our understanding of how climate risk will impact both our physical world and the global system that finances economic growth... Investors are increasingly reckoning with these questions and recognizing that climate risk is investment risk. Indeed, climate change is almost invariably the top issue that clients around the world raise with BlackRock... They are seeking to understand both the physical risks associated with climate change as well as the ways that climate policy will impact prices, costs, and demand across the entire economy... These questions are driving a profound reassessment of risk and asset values. And because capital markets pull future risk forward, we will see changes in capital allocation more quickly than we see changes to the climate itself. In the near future – and sooner than most anticipate – there will be a significant reallocation of capital.
And so on. Read the thing yourself. Most of you will mostly be happy with it. Some of it, ter be 'onest, is just a touch strange: What happens to inflation, and in turn interest rates, if the cost of food climbs from drought and flooding? Well, it might. But food production in the real world continues to increase, and I expect core-cost-of-food to continue to decline as a proportion of total spend, so becoming less important into the future. How can we model economic growth if emerging markets see their productivity decline due to extreme heat and other climate impacts? Well, emerging market productivity compared to the West is so much lower it would be weird if catch-up didn't get them a lot; mostly, they need to fix their crap governance1.

But most of it is sensible, and some rather telling: From Europe to Australia, South America to China, Florida to Oregon, investors are asking how they should modify their portfolios. Yes, that's their major question. Not "how can we make the world better?" just "what should we shift our money into?" That's how things are; the job of govt ought to be guiding them towards "good" answers.

Climate Risk Is Investment Risk

Govt will have to set frameworks, ideally wisely but there's faint hope of that so perhaps we can hope for not too unwisely:
Over the next few years, one of the most important questions we will face is the scale and scope of government action on climate change, which will generally define the speed with which we move to a low-carbon economy. This challenge cannot be solved without a coordinated, international response from governments, aligned with the goals of the Paris Agreement.

Accountable and Transparent Capitalism

Ah, glorious. Companies, investors, and governments must prepare for a significant reallocation of capital... Disclosure should be a means to achieving a more sustainable and inclusive capitalism. I find this a bit odd, too. This is all addressed at least nominally to CEOs, remember. So he's beating them up about how they are threatened that capital will shift, but then the major theme turns out to be transparency, which is largely a red herring (you really don't need to read their reports to know that Exxon is mostly oil). So is this just PR perhaps?

Letter to clients

There is also, as I noted, a letter to clients. It starts Since BlackRock’s founding in 1988, we have worked to anticipate our clients’ needs to help you manage risk and achieve your investment goals. This is something that I wish the govt employee non-biznis folk reading this would more clearly understand: biznis really does want to make it's customers happy; or at least, satisfy their needs. Not of course out of altruism; but because they want their money.

More words: Because sustainable investment options have the potential to offer clients better outcomes, we are making sustainability integral to the way BlackRock manages risk, constructs portfolios, designs products, and engages with companies. We believe that sustainability should be our new standard for investing... sustainability-integrated portfolios can provide better risk-adjusted returns to investors. And so on. But what of the actual concrete changes? Exiting Thermal Coal Producers  is one; that makes sense and by now is I think mainstream. Most of the rest is providing potential investors with more sustainable options and hoping they take them; Joining Climate Action 100+, but I can't say I'm keen on that.

Germany Goes Greener With $95 Billion Push for Train Over Plane

This meeting is bollocks. Germany Goes Greener With $95 Billion Push for Train Over Plane proudly says Bloomberg.
Germany launched an 86 billion euro ($95 billion) plan to modernize and expand its creaky railway system, a move billed as an effort to make transportation greener. The 10-year plan is not only to upgrade rails, bridges and carriages but also build out capacity and electrify more routes so as to lure passengers from cars and planes. The federal government will finance 62 billion euros and state-owned Deutsche Bahn AG is to come up with 24 billion euros... DB, as the railway operator is also known, has been under pressure in recent years to improve punctuality and service standards as its fleet of aging trains failed to keep up with rising passenger numbers and its federal owner kept up pressure on the company to secure dividends. Currently only 58% of rails run on electricity and punctuality on long-distance trains was around 76% in 2019, up one point from a year earlier. Rail travel emits less CO2 pollution than air or road traffic. The company already slashed travel prices across the board by 10% on Jan. 1, after the government ordered a cut in value-added tax on tickets.
And so on. I like trains, really I do. Although I don't use them much any more (mostly, I'm happy to say, because I just don't travel that much any more). However, is what they've done a good idea? How would you even know? If your answer is "yes it's obviously a good idea" then my reply is "but would $195B be better?" Because if it would be, then they've made a distinctly sub-optimal choice, so calling it "good" is odd. If you believe that pols are generally not just wise and well advised, but also able to put aside lobbying pressures and party politics, then you might believe that they've picked the right number. Presumably you'll also believe that HS2 is also a great idea. And can I interest you in this fine bridge I have for sale?

How might we do it otherwise, and use something other than the undoubtedly unsurpassable wit and wisdom of pols? Well, if you don't like hairyplanes because they emit CO2, then you should tax CO2. Which would increase the costs of hairyplanes. If people still flew too much after that, then you'd know that Johannes Public doesn't agree with the pols.

Which brings me back to a rather short conversation with mt on Twatter recently. Well, less of a conversation and more him posting something and me replying. And my reply was to push the prices-as-information theory a-la Hayek. Of which DB's upgrade is not an example. People can signal how they wish to balance cost and convenience by whether they choose to buy plane tickets or train tickets. At the moment the Govt thinks they are buying too many plane tickets. Given that preference, you'd expect investment money to flow into hairyplanes, and that seems to be true. Deciding that you don't like that, and just dumping a wodge of money on DB, is likely to be inefficient. Because how will they know just what to spend it on?


The collection of resources for government financed or sponsored investment often has a substantial disincentive effect on saving, effort and enterprise...  Peter Bauer, Dissent on Development.


At Davos we will tell world leaders to abandon the fossil fuel economy?

tour Greta Thunberg and others, in the Graun - where else? Time to update Skolstrejk för klimatet and see what the "No plan, let alone a plan B" looks like now.

But before that, my pic shows Cadel Evans (141, in red) on the Alp de Huez, on his way to winning the 2011 Tour de France. I thoroughly recommend it, if you like that kind of thing; that stage is here but it's worth stepping back a few to get into the flow.

But back to La Greta:
We demand that at this year’s forum, participants from all companies, banks, institutions and governments immediately halt all investments in fossil fuel exploration and extraction, immediately end all fossil fuel subsidies and immediately and completely divest from fossil fuels. We don’t want these things done by 2050, 2030 or even 2021, we want this done now – as in right now.
How to evaluate this? The idea that this can be done right now is of course absurd. I shall assume that it is but a rhetorical flourish and should not be criticised too harshly. end all fossil fuel subsidies sounds good, but without defining "subsidy" it is meaningless. Happily, GT implicitly defines "subsidy" with The IMF concluded that in 2017 alone, the world spent $5.2tn subsidising fossil fuels, because this can be recognised as IMF working paper 2019: Global Fossil Fuel Subsidies Remain Large: An Update Based on Country-Level Estimates. This means that GT doesn't know what a subsidy is, because that $5.2T represents all kind of things, mostly pollution - not CO2 - effects; which means that to talk of the world "spend"ing $5.2T is just wrong; and to think they could be ended - by just stopping paying out money - is also wrong. This is careless of GT because generally she is spoken of as someone who actually knows what she is talking about.

"Divesting" from FF generally means selling your shares: to someone else. That expresses your disgust quite neatly, but does mean that someone else now owns those shares. They don't just disappear. And, of course you've profited by the sale of a FF related asset, so are morally contaminated. Perhaps you should instead rip up your share certificate? That doesn't help either really: it's like ripping up a five pound note (in the days when notes were made of paper and were weak enough to tear); all that happens is a tiny amount of deflation. Lots of people selling shares will tend to decrease the price of those shares, and will signal to the markets to invest less in those companies; and that brings us naturally on to investment.

And, jolly good, I've managed to find a thread I was looking forHere's a THREAD about divestment (and why it's driven mostly by economics, not good citizenship), theories of change in climate / energy, and the power of tapping into self-interested economic motivations among corporates, banks, and investers. So that says, as I guess we all know, that coal is doomed; probably, it will collapse entirely quite soon. That will be good as it will remove a pile of people pushing for FF, as well as being good for the climate. GT says that since the 2015 Paris agreement, 33 major global banks have collectively poured $1.9tn (£1.5tn) into fossil fuels. That number may be correct, but again GT is making a mistake like she did with subsidies, and one I think Joe Public makes: that isn't the bank's money, cos they don't have money, they have deposits. It's clients money. Clients like, oh... pension funds. Sensibly, GT says it ought to be in every company and stakeholder’s interest to make sure the planet they live on will thrive. Alas, she cannot bring herself to add: and the correct way to do this is Carbon Taxes. I think because that would amount to compromise; and she cannot compromise.


Plastic packaging ban 'could harm environment'?

Plastic packaging ban 'could harm environment' says Aunty:
Consumer pressure to end plastic packaging in shops could actually be harming the environment, a report says. Firms are swapping to other packaging materials which are potentially even worse for the environment, the cross-party Parliamentary group warns. Glass bottles, for instance, are much heavier than plastic so are far more polluting to transport. Paper bags tend to have higher carbon emissions than plastic bags – and are more difficult to re-use.
And so on. This is all tediously predictable; a simple knee-jerk "plastic is bad" is stupid; and the general public I think generally can't cope with subtlety.

But then again, neither can the Beeb. Because if you actually read the report1, you find:
There have been some minor changes, for the most part switching from one single use option to another. These include the use of new types of material to replace some plastic in the bottled water market and moves away from plastic straws and stirrers ahead of the forthcoming ban in England in 2020. But, overall, the proportion of plastic packaging seen on most supermarket shelves, and the amount collected as waste and reported to the Environment Agency, has not altered significantly.
Which I find somewhat cheerful. Supermarkets were using plastic packaging because it made sense, and it still continues to make sense.
another noted: “It’s been mostly complaints, saying that plastic is evil and has no place, regardless of any positives it might have in addressing food waste and what not… But this outrage is not necessarily translating into changes in purchasing habits... customers’ concerns over plastic pollution are not yet evident in what they are buying. One observed: “A lot more consumers are saying that they are already avoiding what they understand as single use plastics – that is a clear and consistent trend coming through our research. The challenge is that’s claimed behaviour and is not necessarily coming through as actual behaviours from consumers yet.” Another was far more blunt: “When it comes down to real consumer behaviour, they ain’t changing yet.”
As far as I can tell the entire "plastic pollution" scare is, in the West, nonsense. See e.g. Stemming the Plastic Tide: 10 Rivers Contribute Most of the Plastic in the Oceans; The Yangtze alone pours up to an estimated 1.5 million metric tons into the Yellow Sea.

Socrates, himself, is particularly missed; A lovely little thinker, but a bugger when he's pissed

From Tamino, some nice graphs about the current situation in Australia. With all the wild excitement, it can be hard to see what's actually happening - after all, recall the Bazillion Rainforest fuss of not long ago.

As to ppn, as Tamino puts it, Australia has had dry years before, and will again. Although 2019 was the driest on record, there’s no trend detectable in rainfall amounts, at least not yet; it looks like an unfortunate but random occurrence. This isn’t climate change, it’s bad luck. And that seems a fair assessment.

As to temperature, clearly that is a record high, and part of a trend; though also clearly above the trendline.

Now I draw your attention to the correlations; wet years tend to be cold, and dry years tend to be hot. I'm doing that by eye; Tamino didn't leave his data lying around and I can't be bothered to look for it; but look at e.g. 2000 (and then 2002), and 2010/11; or 1974. 1994 is less convincing. Anyway, as you'd expect, there's a correlation: a dry year has less moisture to cool the earth by evaporating, so tends to be hot2.

And that then suggests that this year's disastrous fire season is unlikely to be replicated in the near future; if it's caused by the exceptional dryness, then it's bad luck. Anyone wanna bet, that 2020's ppn will be back at or above the bottom pink band; and next year's Temp will be at or below the pink; and next year's fire season will be unexciting?

Recall that we discussed this somewhat in the comments at Climate emergency? in November. At least my thoughts there suggest that yearly averages might not be fine enough1.


1. And now Tamino with prompting has done another post on more regional stuff, but still doesn't find much in the way of trends.

2. Although this isn't obvious when you scatter-plot it; see RR.

Book review: Homo Deus

80694470_3417507671654844_8495632808285306880_o CIP read Homo Deus but didn't really review it. I however am fearless. I was glad to get a chance to read this (it came as a Christmas present, welcomely as a second-hand book) because I'd heard good things about Sapiens. I haven't read that, so I don't know if much of this is recycled from that, but it somewhat feels like it is. However, I didn't get on with it: sorry.

The main point is that it is fat. Bloated. Obese. 100 pages in and he has barely said anything; a page or two would have sufficed. And the few things he has said are unexciting.

He's also careless. Planck is made to say "science advances one funeral at a time" on p 30. But he didn't say that. He said Eine neue wissenschaftliche Wahrheit pflegt sich nicht in der Weise durchzusetzen, daß ihre Gegner überzeugt werden und sich als belehrt erklären, sondern vielmehr dadurch, daß ihre Gegner allmählich aussterben und daß die heranwachsende Generation von vornherein mit der Wahrheit vertraut gemacht ist whose English equivalent is A new scientific truth does not triumph by convincing its opponents and making them see the light, but rather because its opponents eventually die, and a new generation grows up that is familiar with it. This is trivial but suggests that his scholarship, whilst wide, is shallow.

On p 106 he cites Numbers 28 for the statement that the old Jewish temples were swarming with black flies. Of course, that verse says nothing to that effect. And notice what a cheap reference that is; there are many many other statements he makes that should be reffed, in anything vaguely scholarly, but he doesn't. He only tosses off the odd cheap reference, presumably to look good.

Around p 119 there's a jejune1 discussion of why evolution tends to inflame the passions more than relativity, which (characteristically) he broad-brushes into the untrue "no-one gets angry about relativity". Evolution, he brilliantly deduces, inflames people because it is incompatible with having a soul. But of course it isn't (he knows this; on p 122 he comes close to admitting it; but when you're writing at the rate he is, and when you outrank your publisher's reviewer, you're not going to go back and correct your flow).

Part, perhaps much, of the bloat comes from our author being interested in many things, and insisting on weaving those things in, even when he has nothing to say. From p 123 we get a multi-page disquisition into consciousness, which amounts to little other than "we don't know how it works".

He isn't very interested in science, and shows it about as much respect as the Watties. We repeatedly hear about "current scientific dogma" (e.g. p 139). Or "classical economic theories maintain that humans are rational calculating machines" (p 163) - a regrettably unoriginal piece of drivel.

And so ends part 1. Part 2 starts by saying that humanism is the worship of mankind. This is stupid. Probably, he is just trolling. But he needs to do better; he hasn't got much more credit and I will be giving up soon... ah, his trick is becoming clearer. Perhaps it was worth reading: his defn of "religion"  is "to believe in a system of moral laws that wasn't invented by humans but that humans must nevertheless obey" (p 213). But this is a poor trick, and doesn't justify his use of the word "worship". I think... I "believe in" a system of moral laws that was "invented" by humans, though that might depend on how you define the word "invented". So even by his rather creative defn, I'm still not religious. Phew.

On p 222, he tells us confidently that the pope never makes a mistake. This is nonsense. As the good book sayethPapal infallibility is a dogma of the Catholic Church that states that, in virtue of the promise of Jesus to Peter, the Pope is preserved from the possibility of error "when, in the exercise of his office as shepherd and teacher of all Christians, in virtue of his supreme apostolic authority, he defines a doctrine concerning faith or morals to be held by the whole Church."[1] Infallibility is, according to the New Catholic Encyclopedia, "more than a simple, de facto absence of error. It is a positive perfection, ruling out the possibility of error".[2] 

At that point, I gave up. Looking for a review, I find the Economist:
Although there is plenty to admire in the ambitious scope of this book, ultimately it is a glib work, full of corner-cutting sleights of hand and unsatisfactory generalisations. Mr Harari has a tendency towards scientific name-dropping—words like biotech, nanotechnology and artificial intelligence abound—but he rarely engages with these topics in any serious way. Instead, he races along in a slick flow of TED-talk prose. Holes in his arguments blur like the spokes of a spinning wheel, giving an illusion of solidity but no more. When the reader stops to think, “Homo Deus” is suddenly less convincing, its air of super-confidence seductive but misleading.

DSC_3744 A bit more Thucydides. This time from the "Mytilenian Debate". A quick precis of the background for those who have forgotten: war between Athens and Sparta is in its third year; the Mytilenians want to go over to the Spartan side1 and the Spartans promised aid; alas the revolt goes poorly, the Spartans prove fairly crap at sea and Mytilene and Lesbos are retaken. The ringleaders are taken to Athens, and the assembly there - no longer lead by Pericles - in anger and fear condemns all the men of Mytilene to death; but sleeping on it they come to be uneasy, and re-debate. The result - not to spoil the suspense - is a close run thing but is narrowly in favour of not killing everyone. Anyway, that's not my point here; what's interesting here is that Thucydides gives us the "demagogic" (Cleon) and "rationalist" (Diodotus) sides as speeches. This is one of his Dramatic Techniques and makes the whole thing more readable; after a catalogue of near-chaotic events and places which constitutes what happens, it's good to get the politics presented.

Aanyway, my real point was that on this my second reading - my first, several years ago, was mainly to get the story - I'm struck by bits of Cleon's speech I didn't notice before; perhaps I skimmed:
The most alarming feature in the case is the constant change of measures with which we appear to be threatened, and our seeming ignorance of the fact that bad laws which are never changed are better for a city than good ones that have no authority; that unlearned loyalty is more serviceable than quick-witted insubordination; and that ordinary men usually manage public affairs better than their more gifted fellows. The latter are always wanting to appear wiser than the laws, and to overrule every proposition brought forward, thinking that they cannot show their wit in more important matters, and by such behaviour too often ruin their country; while those who mistrust their own cleverness are content to be less learned than the laws, and less able to pick holes in the speech of a good speaker; and being fair judges rather than rival athletes, generally conduct affairs successfully. These we ought to imitate, instead of being led on by cleverness and intellectual rivalry to advise your people against our real opinions.
How Brexit is that? Don't trust experts. If you don't understand things, don't worry, just let your common sense guide you. Don't change your mind. It continues with proving that the M's were particularly evil, deserved punishment, and failure to do so would inevitably cause everyone else to revolt too.

Words had to change their ordinary meaning and to take that which was now given them

A well known passage, but worth quoting while I'm here.
Revolution thus ran its course from city to city, and the places which it arrived at last, from having heard what had been done before, carried to a still greater excess the refinement of their inventions, as manifested in the cunning of their enterprises and the atrocity of their reprisals. Words had to change their ordinary meaning and to take that which was now given them. Reckless audacity came to be considered the courage of a loyal ally; prudent hesitation, specious cowardice; moderation was held to be a cloak for unmanliness; ability to see all sides of a question, inaptness to act on any. Frantic violence became the attribute of manliness; cautious plotting, a justifiable means of self-defence.


1. Athens, though a democracy, wasn't terribly nice as an Empirical Power, the Delian League having decayed into hegemony.

2. If you're wondering about his wonderful memory capable of recording these speeches, be aware that as he puts it sometimes he made people say "what was called for in each situation". And from tis distance, who are we to doubt this?

3. Pic: the Corinth canal. Somewhat beyond the strength of the Antients. But they did have a cut / road for dragging ships across.

Close elections are bad elections; what we need is social consensus

Screenshot_20191223-225856 mt Twote:
Close elections are bad elections. What we need is social consensus. Anything important decided by a narrow fraction of the most disengaged voters is destabilizing.  Professionalization of politics is the problem, not the solution.
Complaining about something like politics becoming more professional, or more efficient, is about as much use as - and indeed, is very similar to - complaining about evolution. But I'm used to disagreeing with mt over politics, so skip that bit as a detail and come to the "close elections" thought.

About which, as I half said in a different context (oh, there are so many thoughts in the world to write down!) in Men spake from God being moved by the Holy Ghost / Every man in his own language, I feel I've said before but can't find, so will say again:

Politics tends to produce close results1, but not consensus2. Nominally, pols are supposed to seek and promote consensus, and mt is still yearning after that idea, but I see little evidence that it is a major part in practice. And politics is backed by coercion: at least in majoritarian states: if you win, you get the power to impose your - sorry, the people's - will; this tempts far too many people. This tends to leave the middle ground barren and dead, populated with the corpses of those attacked by both sides. The solution, of course, is to move as much as possible out of the purview of politics, since anything done there will inevitably be fought over as a zero sum game. And move it out into the free market, where individual decisions are indeed made by agreement.


I should have reffed Aristotle's politics and the quote from Hayek: It is not democracy but unlimited government that is objectionable...


Does J R Oppenheimer ask: can science provide better models for democracy?


1. In an idealised society with a spectrum of opinion categorisable as from Left to Right, imagine two parties competing for votes, sure of all those on the side of the spectrum away from the other party; inevitably, they migrate to the centre. This was Tony Blair's chief idea, and lest you dismiss it too readily, notice that he was the only Labour to win an election for uncounted moons. I prefer conviction politicians - Blur IMO had no real ideas about what to do once he achieved power. The idealisation applies but in more blurred form in more complex scenarios.

2. Having commented on closeness, I feel the urge to comment on consensus too, since it is so strikingly absent. At least in the UK and USA; I'm rather less familiar with our Continental friends or those further abroad. But it is hard to know what to say. The UK is split by Brexit as one axis and but whether you dislike Corbyn or Bojo more on another, and that's not helpful. The USA is, apart from the perhaps-superficial Trump/Populist split, also divided between "free market" vs "progressive", but muddily, possibly leaving room for consensus in the details even if on principles there can be no meeting.

3. My picture shows Henry Worsley, who has nothing at all to do with this article. But I love the picture; I got it from the New Yorker. They shoved it into my fb feed for months on end and I finally got round to reading it. To my surprise, it doesn't show a USAnian: to me, he looks like one of the cowboy pilots from Catch-22, or the mad ones from Dr Strangelove. But no, just an Englishman.

Praise is due to all who respect justice more than their position compels them to do

DSC_3794 A fragment from The Peloponesian War. The Athenians are talking to the Spartans, trying to persuade them not to join the Corinthians; and so are defending their own actions and empire. They can't argue that they have been wholly good, and instead Thucydides1 reports them as saying:
praise is due to all who, if not so superior to human nature as to refuse dominion, yet respect justice more than their position compels them to do. We imagine that our moderation would be best demonstrated by the conduct of others who should be placed in our position; but even our equity has very unreasonably subjected us to condemnation instead of approval. Our abatement of our rights in the contract trials with our allies, and our causing them to be decided by impartial laws at Athens, have gained us the character of being litigious. And none care to inquire why this reproach is not brought against other imperial powers, who treat their subjects with less moderation than we do; the secret being that where force can be used, law is not needed. But our subjects are so habituated to associate with us as equals that any defeat whatever that clashes with their notions of justice, whether it proceeds from a legal judgment or from the power which our empire gives us, makes them forget to be grateful for being allowed to retain most of their possessions, and more vexed at a part being taken, than if we had from the first cast law aside and openly gratified our covetousness. If we had done so, not even would they have disputed that the weaker must give way to the stronger. Men's indignation, it seems, is more excited by legal wrong than by violent wrong; the first looks like being cheated by an equal, the second like being compelled by a superior. At all events they contrived to put up with much worse treatment than this from the Mede, yet they think our rule severe, and this is to be expected, for the present always weighs heavy on the conquered. This at least is certain. If you were to succeed in overthrowing us and in taking our place, you would speedily lose the popularity with which fear of us has invested you, if your policy of to-day is at all to tally with the sample that you gave of it during the brief period of your command against the Mede.
I think it fits the USAnian Empire well.


1. Crawley translation from Gutenberg. The Warner translation, which I'm reading, is somewhat different and appears to be more popular to quote. So you can key it if you want to, it starts "Those who really deserve praise are the people who, while human enough to enjoy power, nevertheless pay more attention to justice than they are compelled to do by their situation".

2. Yes I know: Mycenae predates this period by many years.

Sigh: DOE announces another lightbulb efficiency rollback

IMG_20191217_182721_122 More broken logic. Well, not really even an attempt at logic. The story from The Hill via Twatter:
In its latest move to roll back energy efficiency measures, the Department of Energy (DOE) announced Friday that it would block a measure designed to require more efficient lightbulbs, arguing the policy would be too expensive for consumers.  The announcement applies to widely-used, pear-shaped incandescent lightbulbs. Coupled with another controversial rule finalized in September, the move cements two remarkable decisions taken by the department this year to hamstring efficiency requirements for nearly every type of bulb used in America. The announcement follows earlier messaging from the department that market forces, and not the government, should guide consumer choices.
And so on. The lack of logic is:
consumer protection groups and environmentalists have widely panned the measures, saying consumers will be stuck with a higher electric bill spurred by inefficient bulbs... This law should have saved U.S. households more than $100 annually... You wouldn’t use a phone from the 1870s, so why use Edison’s 1870s light bulb?
But of course the change merely allows people to choose their own bulbs. If they value saving $100 per year, then they'll do that, and the law will have no effect. But they have the choice not to, if that's what they prefer. Those who think that the entire populace are feckless incompetents will argue that people should not have the choice, but I can't support that. As to phones, people migrate to modern phones with no coercion from the govt, so if that's your analogy, it argues against the regs.


* Ra ra: If you like your lightbulbs, you can keep your lightbulbs! The Obama Admin tried to limit Americans to buying more-expensive LED bulbs for their homes—but thanks to President

Historic Urgenda Climate Ruling Upheld by Dutch Supreme Court

80657110_1340083109521339_6781348271953543168_o I haven't written about Urgenda before. As they say themselves On 24 June 2015 the Urgenda Foundation, together with 900 citizens, won the Climate Case against the Dutch Government, forcing it to take more measures against climate change. On 9 October 2018 the judge in High Court again ruled in favour of Urgenda and the climate. The government appealed again. The final ruling of the Supreme Court will be on 20 December 2019. And Climate Liability News will tell you about the just-in victory: The HAGUE—The Netherlands’ Supreme Court upheld the landmark ruling in Urgenda v. the Netherlands, announcing its decision on Friday that governments have a human rights duty to protect their citizens from climate change. The strongly worded judgment orders the Dutch government to cut its greenhouse gas emissions by 25 percent by the end of 2020, compared with 1990 levels.

As I think I've said before, I don't like this version of "human rights". I like the version of the US constitution, most notably the First AmendmentCongress shall make no law respecting an establishment of religion, or prohibiting the free exercise thereof; or abridging the freedom of speech, or of the press; or the right of the people peaceably to assemble, and to petition the Government for a redress of grievances. This is "rights" as it should be done: by preventing govt f*ck*ng around with you. That way, you don't have to worry what the phrase "human right" even means. But when you end up deriving a "right to climate" from the state had clear obligations to protect the environment under Articles 2 and 8 of the European Convention of Human Rights involving the right to life and the right to a private and family life then things have, in my opinion, gone wrong. Read my insightful review of Ann Leckie's The Raven Tower for more.

And, of course, I think the whole targets idea is wrong.

On the overall concept, which is citizens suing their govt to do something, I think that is intrinsically weird. Holland is a democracy. They elect people to represent them. Attempting to manage govt through the courts is odd. The courts should be a check on the abuse of power by the govt; and on the govt over-stepping its authority; but I don't like them being used to prod the govt into action. In that case, your remedy is to get another govt. If you reply is "but a different govt wouldn't act either" then my reply is "that is telling you something rather important". The only counter argument to this is that it acts to prevent govt lying: if they've got in by saying they'll do X, then I have some sympathy with the courts forcing them to do X. But I don't think that applies in this case.

Climatic Impacts of Wind Power

80620812_1339153616280955_2067261372671983616_o By Lee M. Miller and David W. Keith in Joule. In 2018, so I'm well behind the times; but so is RS. This is fundamentally the same idea as Zhou et al. in 20121: wind turbines mix the boundary layer and so tend to warm the surface when it is colder than aloft. The effects are significantly larger at night than daytime, as you'd expect (during the day gradients are small anyway due to solar mixing from the sfc; at night the sfc cools). There are two elements of confusion to address. The first is trivial: the turbines are not generating any significant amount of heat; they're just mixing it. This is obvious and I only mention this because people have otherwise got confused in the past. And secondly, that while you might want to therefore say "there is no contribution to rising global temperatures and their associated problems" (especially if you're the AEWA) that's not really true. Because as conventionally understood GW applies mostly to the sfc temperature, and wind farms do have the potential to change that.

This is but a humble regional model, and so can't give you global impacts. Possibly, warming locally might be mitigated by cooling elsewhere; but then again it might not be.

Comparing Climatic Impacts to Climatic Benefits

So does this have any bearing on the GW-related virtues of windfarms? If you're the AWEA the answer is of course no no good grief what were you thinking? The Science Media Centre has some reactions most of which are also keen to minimise the relevance of this; the only one worth reading is by Stephen Mobbs.

The paper says "We find that generating today’s US electricity demand (0.5 TWe) with wind power would warm Continental US surface temperatures by 0.24 oC... The warming effect is... large compared with the reduced warming achieved by decarbonizing US electricity with wind". But what is even the correct measure? You should compare the (global) changes, not just the changes over the US... they say "Assuming emissions cuts are implemented globally, then the climatic impacts of wind power affecting the US in 2100 are approximately equivalent to the avoided warming from reduced global emissions" which I think implies a sort of net loss until 2100.

It's also true that "the direct climatic impact of wind power is immediate but would disappear if the turbines were removed, while the climatic benefits of reducing emissions grows with the cumulative reduction in emissions and persists for millennia". However, in line with my std.policy that you shouldn't care too much past 100 years out, I don't think you should weigh the effects out to millenia highly. You might also attempt to assert that warming at night when it's colder anyway is better than warming during the daytime, perhaps.

What I said last time

To be honest, I should quote what I said last time, though of course you can read it all from the link. Most of the previous post was debunking misunderstandings, but as to the GW stuff I said: But if you’re silly, like the Torygraph, you find yourself obliged to headline your story Wind farms can cause climate change, finds new study. The actual article itself isn’t too bad – it correctly notes this is a local effect, largely night-time only, and it permits itself a little speculation that if done on a large enough scale this might just be noticeable regionally. And, being generous, you could call this “climate change” – though to most people, “climate change” will mean global climate change, which this isn’t. That was true in the old context, which was just about small - by comparison with the considerations of the current paper - wind farms. But is perhaps a little too dismissive of the potential GW impacts.


1. Except Zhou was real observations not models.

They are openly admitting they have no intention of trying to slow climate change?

79756170_1337096576486659_3664121601915355136_n More anguished twatting about oil companies: ExxonMobil’s 2019 Outlook for Energy predicts “no reductions in carbon dioxide emissions from the energy sector through 2040—and no date at which emissions reach net zero”. They are openly admitting they have no intention of trying to slow climate change.

This is just a dumb category error, confusing predictions with intentions. The obvious analogy is with IPCC / SRES (or whatever replaces SRES; see how out of date I am): just because the IPCC predicts / projects future CO2 emissions increasing doesn't imply they have no intention of helping reduce them.

Exxon's outlook for energy - which, obviously, I haven't read; see-also ExxonMobil: Positioning for a Lower-Carbon Energy Future? - is their best-guess at the future. It's them trying to read the tea-leaves, guess what will happen, what people will want, how the idiot pols will fuck things up, and so on. All of that occurs within a political and societal context, which they're trying to guess. But asking them to be in control of that context is ridiculous. And do people really want Evil Fossil Fuel Companies in control? Of course not.

Society is a big complex self-organising institution with some top-level control from govt, usually done badly. Within that various instituions like EFFCs operate in response to people's desires. If you want what they do to change you need to change your desires. Saying you want lower CO2 emissions and then flying off to COP25 is about as much use as a fat man saying he wants to be thin while still scoffing all the pies - see-also Climate chickenhawks. You should pay more attention to what people and pols do, rather than what they say. the key phrase is "revealed preferences". If you want EFFCs to count the SCC, then impose a carbon tax.

Exxon Found Not Guilty of Deceiving Investors Over Climate Risks

79024836_1331247397071577_3374945770317807616_o This was the case that I commented on in L'affaire Schneiderman and noted briefly in refs a month ago. Broadly speaking though I thought the case silly and politically motivated and didn't much cover it. Summary: the City of New York decided to use some valuable taxpayer dollars suing Exxon for securities fraud and racketeering: their assertions were that Exxon had made misleading declarations to investors, and had committed deliberate fraud. The latter allegations were even less plausible than the former and NY dropped them a month back. Now Exxon has been found not guilty of the former.

The case was always stupid. In practical terms, NY was trying to show that Exxon had failed to tell investors that there were risks of "stranded assets" and that it's business could be seriously impeded by action on GW. And this is drivel because no sensible investor could possibly be unaware of those issues; there was no need at all for Exxon to tell anyone; and, anyway, they had. So the case was never about bad behaviour by Exxon; it was just an attempt to sue someone that NY didn't like on a technicality. And, deservedly, it failed.

Sadly CLN doesn't link to the judgement, so I have to go to the Dork Side for that. I've read / skimmed it all. I think that NY were hoping for a technical victory: that Exxon's words, though irrelevant to any investor's decision, nonetheless could be construed as misleading. But the judge doesn't even give them that, deciding that there must be "actual significance to the deliberations of the reasonable shareholder", and that's not going to fly. The allegations are mostly around a couple of reports from Exxon in March 2014, said to be misleading, but as the court notes "there was no evidence adduced at trial that the publication of the march 2014 reports had any market impact...". And just to grind it in, "evidence at the trial revealed that Exxon executives and employees were uniformly committed to rigourously discharging their duties in the most meticulous and comprehensive manner possible". Perhaps importantly, hizzoner notes that NY offered no testimony from any investor who claimed to have been mislead. There's also some stuff about Roger Reed, a market analyst, who didn't change anything due to the March reports, so that's pleasingly empirical. Also, NY's experts seem to have been a bit crap compared to Exxon's ("the testimony of the expert witnesses called by the Office of the Attorney General was eviscerated on cross examination").

If all this sounds like I'm gloating, I am. This was a stupid case that distracted attention from actual real world problems.

This may be a good place to link to my Exxon disclaimer, which I find I first noted in 2006 and certainly re-said in 2015.


* “Barking Cats” by Milton Friedman h/t TF


If you’re a climate or energy researcher, chances are the fossil fuel industry owns you?

evil If you’re a climate or energy researcher, chances are the fossil fuel industry owns you was a cheery Twit by Benjamin Franta. A variety of people were tewwibly offended, but really, the question should have been why did they expect any sense out of him in the first place? The entire Exxonknew drivel he's promoting is drivel and always has been. I felt obliged to tell otherwise intelligent people Yes, which is why it's all drivel. There's nothing at all new there; and the intent to report is as though it was is, is spreading lies / PR. As I said "you were all happy with F when he was spreading drivel you liked". Now it's drivel you dislike, and you're all astonished.

But it perhaps needs laying out in more detail than Twatter is capable of coping with, so here (for those who found Early oil industry knowledge of CO2 and global warming? for some reason hard to understand) are some words.

1. Back in Ye Olde Dayes, GW was but a twinkle in people's eyes and so there was lots of speculation and inquiry around the subject, including stuff written by Exxon, and even by coal companies.
2. The idea that anyone actually knew exactly what was going on, or could make confident predictions, is wrong. See for example In the decade that ran from 1979 to 1989, we had an excellent opportunity to solve the climate crisis? for my discussion; but I think it's definitely correct that any date before 1990 is unreasonable. Yes, it's possible to cherry pick pictures that people created in the 80's and declare them to be uncannily prescient, but this is also silly. Incidentally, I think that predicting future CO2 turned out to be much easier than anyone expected. But just cos you know now that it was accurate(ish) doesn't mean you knew it then.
3. The idea that one graph by one person at Exxon proves that "Exxon knew" is also drivel. Exxon is quite a large organistaion. It doesn't have one mind that is always in full agreement with itself and that knows everything it is doing, any more than the USofA does.
4. Everything that the Evil Fossil Fuel Companies knew then was public. So if your complaint is that all this was secret, then you're an idiot. If you think the public were not fully informed of all this vital information, then your complain should be with the govt. The govt is the entity charged with spreading such vital-to-the-general-public information; not EFFCs. See-also #exxonlied;  or The Climate Deception Dossiers? Oreskes is the leader in this kind of drivel, writing stuff like "At least fifty years ago, Defendants-Appellants (hereinafter, “Defendants”) had information from their own internal research, as well as from the international scientific community, that the unabated extraction, production, promotion, and sale of their fossil fuel products would result in material dangers to the public. Defendants failed to disclose this information...". If you can't tell why this is drivel, you haven't been paying attention.

It is possible to complain that after the naive early days, the EFFCs starting spreading misinformation. I think this is a valid complaint (see-also What I said about Exxon). But, it really isn't that exciting. As well as misinformation from the EFFCs there was also lots of good information available from govts and the IPCC; anyone who wanted to be well informed could be; those who wanted to be lied to, were. To get round this problem you need a population that wants to know the truth. Alas, such are hard to find.


Craig Loehle stops speaking

In Craig Loehle speaks I noted CL editing his wiki article. But now - see Wikipedia:Articles for deletion/Craig Loehle - he is no more (recent archive). The nomination was Fails WP:PROF and WP:BIO generally as there do not seem to be multiple independent sources written about the person. The sources in the article are all either WP:SELFPUB, articles he published, or extremely incidental notice that do not highlight the importance of the person. Note also that there may be some WP:SOAP going on at this WP:FRINGEBLP. jps (talk) 10:50, 20 November 2019 (UTC) and there wasn't a lot of interest.

The only dissent was Keep. Loehle is a scientist who has worked at research institutes throughout his career. So WP:NPROF is the standard to apply, rather than GNG. And his citation record looks like it passes WP:NPROF C1 — 7000 citations, nearly 20 articles over 100 citations, etc. He is certainly fringe, and the article needs to put the fringe-ness in better context in some places. Russ Woodroofe (talk) 12:05, 23 November 2019 (UTC). The response to this is the obvious; NPROF #1 is The person's research has had a significant impact in their scholarly discipline, broadly construed, as demonstrated by independent reliable sources and CL certainly fails that; and the other criteria too. Our Keeper replies that CL has a respectable 7k cites, which seems to be true; JA by contrast has 9k. But then again, no-one could be bothered to argue, which kinda makes him NN. There's also his 2007 article (which seems to have been taken seriously enough by the mainstream to push back against), but that was the crappy E+E thing that RC amongst others took down.


Election 2019: Boris Johnson Top Beneficiary of Donations from Supporters of Climate Science Denial?

77426606_1312780438918273_6451873208894226432_n It's the smoggies again. What they've done is looked at the donations, seen who they are from, and done their best to give you the impression that the Tories are being supported for GW denial. But I don't think you can deduce that from their data and analysis. Here's their data. First on the list is Neil Record, with $450k  in total, 10% of the total. He is, sez wiki, a British businessman, author and economist who founded Record Currency Management, one of the earliest specialist currency managers. Record was one of the pioneers of currency risk management. In 2003 he wrote Currency Overlay, the first textbook on the subject. He was a short listed entrant for the 2012 Wolfson Economics Prize for his work on the Eurozone crisis. In short, an archetypical Tory donor. That he also happens to chair the evil GWPF1 is a fact but likely has little to do with his donations. Next, with £228k or 5% of the total, is Edward Atkin a businessman, investor and entrepreneur based in the UK and was CEO of Avent.; his sin is to donate to the GWPF, and indeed this is a sin. But again, he's an archetypical Tory donor.

But why are we pissing about with these minnows when the vast bulk - £4,277k - comes from Michael HintzeSir Michael Hintze, GCSG, AM (born 27 July 1953) is a British-Australian businessman, philanthropist and Conservative Party patron, based in the United Kingdom. By now, I'm sure the pattern is obvious. Curiously, the smoggies nowhere notice that more than 80% of the donations came from this one source. Perhaps because his links to the GWPF are rather weak, which throws the entire thing into doubt. The smoggies manage Stance on Climate Change: While Hintze avoids public statements, he is reportedly one of the earliest financial backers of the UK’s only climate science denial thinktank the GWPF. A dedicated supporter, he attended the group’s 2017 annual invitation-only lecture delivered by former Australian Prime Minister Tony Abbott but rather noticeably don't give any amount donated.

So is it bad to receive money from bad people2? If person A funds activity B and C, does that tar activity C with the evils of activity B? For example, I (well, we) generally donate to Wintercomfort for the homeless in Cambridge, usually just before Christmas... so this year's is about due. But I also staunchly defend small govt and rage against regulation. Are they tainted by that? I very much doubt they share my opinions. I am being somewhat facetious; a pattern of behaviour may be considered significant; but really, do you need any more reasons to dislike the Tory party? Their resolutely anti-business and pro-Brexit stance is enough for me.

List of scientists who disagree with the scientific consensus on global warming

75653337_1304605139735803_8533122577084710912_o Wiki seems to be having one of it's bouts of madness; see [[WP:FRAM]] for part of it. The bozos decided to rename "Climate change" as "Climate change (general concept)" and now the fuckwits have decided to delete "List of scientists who disagree with the scientific consensus on global warming". I despair sometimes; soon we'll be left with nothing but Pokemon cards. Archive.is has a reasonably up to date version here should you or I ever want it.

Fortunately it hardly matters any more. The web is saturated with mostly sensible things about GW.


Let’s have more talk of “magic money trees”, by Scott Sumner


Pielke contra mundum

75349072_1304046896458294_3397302797375373312_n Oh noes, not again. Still it's an entertaining distraction from the faithful war reenactors. My headline is from Brideshead of course (I was of that vintage) but apparently it has history. How appropriate.

This is all about RP Jr's No, Hurricanes Are Not Bigger, Stronger and More Dangerous. A statement with which - to revel5 my prejudices - I have a great deal of sympathy6; perhaps also Climate emergency? applies. That's in well-known academic journal Forbes1, and is a response to Normalized US hurricane damage estimates using area of total destruction, 1900−2018 by Aslak Grinsted, Peter Ditlevsen, and Jens Hesselbjerg Christensen in PNAS November 11, 20193. The bastard paper (which I'll call G19 following RP) is paywalled alas, though happily that spares me the trouble of reading it, but I can show you the abstract:
Hurricanes are the most destructive natural disasters in the United States. The record of economic damage from hurricanes shows a steep positive trend dominated by increases in wealth. It is necessary to account for temporal changes in exposed wealth, in a process called normalization, before we can compare the destructiveness of recorded damaging storms from different areas and at different times. Atmospheric models predict major hurricanes to get more intense as Earth warms, and we expect this trend to eventually emerge above the natural variability in the record of normalized damage. However, the evidence for an increasing trend in normalized damage since 1900 has been controversial. In this study, we develop a record of normalized damage since 1900 based on an equivalent area of total destruction. Here, we show that this record has an improved signal-to-noise ratio over earlier normalization schemes based on calculations of present-day economic damage. Our data reveal an emergent positive trend in damage, which we attribute to a detectable change in extreme storms due to global warming. Moreover, we show that this increasing trend in damage can also be exposed in existing normalized damage records by looking at the frequency of the largest damage events. Our record of normalized damage, framed in terms of an equivalent area of total destruction, is a more reliable measure for climate-related changes in extreme weather, and can be used for better risk assessments on hurricane disasters.
So, the problem here is... actually, let's go back a step. The problem here is that people are desperate for something sexy to be caused by CO2 increasing. The obvious one - that it's getting warmer, duh - just isn't sexy enough because it's too slow. But it's quite well observed and statistically tractable: you can clearly see the signal from the noise. It would be so much better if something deeply erotic like hurricanes could clearly be getting worse under GW. Unfortunately, the hurricane observation record isn't brilliant, and the record of economic damage is dominated by enormous increase in "exposed wealth" as more and more is built on shorelines; and as money shifts to Florida and so on. G19 acknowledge this problem and attempt to dance around it.

Notice that the abstract talks of the record of economic damage from hurricanes, but the sexed-up "significance" header says The frequency of the very most damaging hurricanes has increased at a rate of 330% per century. This of course what made it's way into every newspaper's headlines; and it is the first point to draw RP's ire: it purports to say something about climatological trends in hurricanes, but it uses no actual climate data on hurricanes. That’s right, it instead uses data on economic losses from hurricanes to arrive at conclusions about climate trends. Since RP has done a lot of analysis on economic damage - indeed, G19 are using his dataset, or some version thereof - this sorta sounds like a quibble. But he continues From 1900 to 1958, the first half of the period under study, NOAA reports that there were 117 total hurricanes that struck the mainland U.S.. But in contrast, G19 has only 92. They are missing 25 hurricanes. In the second half of the dataset, from 1959 to 2017, NOAA has 91 hurricanes that struck the U.S., and G19 has 155, that is 64 extra hurricanes4. And that sounds like it might matter. So I think G19 owe him a reasoned reply on that.

His second and larger point is that G19's dataset isn't homogeneous: The dataset on losses from hurricanes used by G19... was initially created about a decade ago by a former student and collaborator of mine, Joel Gratz, based entirely on our 2008 hurricane loss dataset (which I’ll call P08)... created a new hybrid dataset, from 1900 to 1980 the ICAT dataset is based on P08 and for 1980 to 2018 it is based on NCEI. This is hugely problematic for G19... the result is a data incontinuity that introduces spurious trends to the dataset. This also sounds like a problem that needs to be addressed.

AG responds, but alas he does so on Twatter which is a totally shit venue for writing coherent thoughts in. He does have his own website but alas it's badly out of date; hopefully he'll write something clearer and at length soon.

RP asserts that the IPCC backs up his position, which from memory I think is correct. Browsing, the IPCC AR5 SPM says nowt about hurricanes; in particular the Detection and Attribution of Climate Change section very sensibly concentrates on the unsexy but observable stuff. Chapter 2 says that AR4 concluded that it was likely that an increasing trend had occurred in intense tropical cyclone activity since 1970 in some regions but that there was no clear trend in the annual numbers of tropical cyclones. Subsequent assessments, including SREX and more recent literature indicate that it is difficult to draw firm conclusions with respect to the confidence levels associated with observed trends prior to the satellite era and in ocean basins outside of the North Atlantic... In summary, this assessment does not revise the SREX conclusion of low confidence that any reported long-term (centennial) increases in tropical cyclone activity are robust, after accounting for past changes in observing capabilities. More recent assessments indicate that it is unlikely that annual numbers of tropical storms, hurricanes and major hurricanes counts have increased over the past 100 years in the North Atlantic basin. Evidence, however, is for a virtually certain increase in the frequency and intensity of the strongest tropical cyclones since the 1970s in that region. And so on. I got bored. If you can find the IPCC saying something dead exciting on the subject do let me know.

I have a feeling that some of the sound and fury of the argument comes from not clearly distinguishing between all hurricanes and the most powerful ones. Implicitly, G19 only finds trends in the most destructive? That sounds like a familiar theory. But of course, they are rarer, and so your stats become even noisier.


1. I snark by sheer reflex; of course, a rapid-response is entirely reasonable; this is this week's news; asking for RP to wait until next week, let alone for the sluggish and uncertain journal response times2, would be unreasonable.

2. There's a fun anecdote in the bio of Schroedinger I'm currently reading: the Prussian academy was noted for the speed of publication of it's Sitzungberichte: two days after a manuscript was received, the proofs were brought to the author by a messenger boy who would wait while the author corrected them.

3. Notice how carefully I link this all up. I do it at work too. So many people don't, and you'd be amazed at how hard it is to get from a to b if you haven't left breadcrumbs.

4. Why the miscounts? According to RP Part of this difference can be explained by the fact that G19 focus on economic damage, not hurricanes. If a hurricane from early in the 20th century resulted in no reported damage, then according to G19 it did not exist. That’s one reason why we don’t use economic data to make conclusions about climate. A second reason for the mismatched counts is that G19 counts many non-hurricanes as hurricanes, and disproportionately so in the second half of the dataset.

5. I meant reveal of course, but now I notice the typo it's also rather appropriate, I do revel in this stuff and my prejudices in particular.

6. Pointing out that everything is so statistically woolly that what RP really means is not that we have strong evidence for no trend, but that we have no strong evidence for a trend, would be tedious.


Here's Pielke Jr in 2014 feeling good about ICAT data - AG still dumping stuff on Twatter instead of writing a coherent response.
