QotD: Millenarianism, left and right

Filed under: Media, Politics, Quotations, Religion, USA — Tags: , , , — Nicholas @ 01:00

Secularists and leftists enjoy sneering at conservative Christians who believe in the Rapture and other flavors of millenarianism. Reasonably so: it takes either a drooling idiot or somebody who has deliberately shut off most of his brain, reducing himself to an idiotically low level of critical thinking, to believe such things. The draw, of couse, is that each individual fundamentalist implicitly believes he will be among the saved — privileged to honk a great big I TOLD YOU SO! at all those sinners writhing in the lake of fire.

It is therefore more than a little amusing to notice how prone these ‘sophisticated’ critics are to their own forms of idiotic millenarianism.

Anybody remember Paul “Population Bomb” Ehrlich? This is the guy who predicted that megadeaths from global famine would be the defining feature of the 1970s. Or Jeremy Rifkin, the guy who told us all in 1986 that the Frostban bacterium engineered to protect plants against cold snaps would mess up the Earth’s climate? Or the brigade of self-panickers (Carl Sagan was briefly one of them) who warned us all back around 1980 that an impending Ice Age was about to destroy civilization? Or, hey — how about the ozone hole; remember when we were all going to die of UV-B-induced skin cancer?

It’s easy to laugh at those particular doom-mongers now; there has been plenty of time for their predictions to fail. But we have plenty of apocalypse merchants peddling equally silly scenarios, on equally thin evidence and bogus reasoning, today. And the same ‘sophisticated’ secularists who lapped up Paul Ehrlich’s nonsense are swaying to the Gospel shout of global warming and “peak oil” — just as self-hypnotized, and just as stone-stupid, as an Ozark Mountains cracker at a tent-revival meeting.

Rather than getting to gloat over sinners writhing in a lake of fire, the draw is getting to feel superior to capitalists and Republicans and Americans; they will all surely Get Theirs and starve in their SUVs when the Collapse Comes, while virtuous tree-hugging Birkenstock-wearers, being in a state of grace with Gaia, will retire to renewable-energy-powered communes and build scale models of Swedish socialism out of macrame supplies or something.

The hilarious part is how self-congratulatory the secularist millennarians are about their own superiority over the religious ones, when in fact the secondary gain from these two kinds of delusional system is identical.

Latest warnings about climate change to mean higher wine prices … maybe

Filed under: Environment, Europe, France, Wine — Tags: , , , — Nicholas @ 06:00

London’s local Metro newspaper recently published a scary article about rising temperatures in wine regions across the world and the likelihood of driving wine prices much higher. Colour me skeptical, frankly. Also of a doubting disposition, Paul Austin Murphy indulges in a good, old-fashioned fisking of the alarmist article:

Now here, in all its glory, is a supremely tangential link (found in a Metro article called ‘Global warming is now messing with wine, so can you PLEASE STOP WRECKING THE WORLD‘):

    Global warming is “going to up the price of wine across the board”.

Readers may want to know the details about this fatal connection between man-created global warming and the high price of wine. Though — it must be said straight away — this can’t always the case at present. It must surely depend on which wines you like and where you buy your wine from.

Anyway, this is the hard science bit; so pay attention and put your white coats on. Here goes:

    “Researchers have suggested that rising temperatures in Europe are likely to increase the cost of labour in vineyards, noting that as heat rises in August, a month when a significant amount of the harvest is brought in, there’s a 15% drop in the amount of time labourers are able to work.

    “There’s also a drop in productivity, slowing down the wine production process.”

That’s odd. On average heat always rises in August in most European countries. Metro doesn’t really make it clear if these natural — as well as annual — increases have themselves increased. It also says that “[r]esearchers have suggested”. Yes, they’ve suggested. That’s a very loose word. Though it’s obviously a very precise and important word if you like your wine and you’re also against man-caused global warming.

It’s also the case that in several European wine-producing countries, cold weather is much more of a problem for the wine industry than hot weather (France, in particular). A “hot” vintage in France is very often associated with extremely high quality wine from that vintage.

Another study has admitted that this catastrophic effect on wine production hasn’t been replicated elsewhere. Metro says:

    “Andreas Flouris of the School of Exercise Science at the University of Thessaly reckons that the results of the small-scale study could easily repeat in California, across Europe, and in Australia — so all our wine could be set to hike up in price.”

Now if this wine catastrophe hasn’t yet happened in “California, across Europe, and in Australia” — then where, exactly, has it happened? The initial study mentioned that “most European countries” have been effected by it. (Which ones?) This other study says that it hasn’t yet occurred “across Europe.” How do we make sense of these two seemingly contradictory phrases?

It’s not just about cost. (Though, for Metro, it’s mainly about the cost!) This is also about taste. Metro tells us that

    “[i]ncreased heat is also affecting the taste of wine, damaging the quality of grapes across Europe and shortening the growing season”.

All this — if true — will also affect prices. Shorter growing seasons will certainly affect the price of wine — or at least certain wines from certain countries. This is strange. One main reason why the United Kingdom doesn’t produce much wine is its shortage of warm weather. (British wine makes up 1% of the domestic market.) Yet if temperatures keep on increasing, then surely more wine will be produced in England. That will also have a positive effect on the price of wine! Why doesn’t Metro mention that?

Now what’s all this going to do to London’s dinner-party circuit? I mean Metropolitans are already suffering from severe “austerity”. Add 50 pence (or less) to a bottle of wine and then what have you got? Massive poverty among London’s professional political Pharisees (who also like wine).

It’s fascinating that the Metro author tries to imply that hot weather in (parts of) Europe will somehow have a knock-on effect in California and Australia, isn’t it? The two latter wine-producers are known for their consistency between vintages, because they are warm-weather regions where the grapes are generally able to mature to full ripeness every year almost without fail. Cool climate regions (like Ontario, for example) have much greater variation from vintage to vintage because the local weather varies significantly and the grapes are not always able to fully ripen before they have to be picked (this is more true of red than white grapes, which tend to ripen sooner and can be picked earlier than the red grapes).

“Donald Trump and Al Gore [are,] politically speaking, […] brothers from different mothers”

Filed under: Liberty, Politics, USA — Tags: , , , — Nicholas @ 03:00

Here’s Shikha Dalmia with an opinion to offend both left and right equally:

Donald Trump and Al Gore would no doubt cringe at the thought that politically speaking, they are brothers from different mothers. After all, what do the Republican president and the Democratic presidential wannabe have in common besides the fact that they are both old, white, pompous dudes who live in mansions and hate Hillary Clinton?

Whether they realize it or not, they both believe in the precautionary principle — the notion that even a small chance of a catastrophic event requires sweeping measures to avert it. Nor do they care about the costs of these “sweeping measures” — both in terms of money and individual liberty.

Their only disagreement is about the events in question: Trump invokes this principle in his crusade against Islamist terrorism — and Gore and his fellow global warming warriors against climate change.

Dick Cheney famously declared that if there was even a “1 percent chance” of another 9/11-style attack by al Qaeda, “we have to treat it as a certainty in our response.” For all of Trump’s criticisms of the Iraq War, he has a natural instinct for this kind of excess. No sooner did the dastardly Manchester attack occur than Trump reiterated, as he had in his inaugural address, that this “wicked ideology must be obliterated.”


Given that the odds that Americans will perish in any terrorist attack — not just those involving Islamists — on U.S. soil is 1 in 3.6 million per year — if the trends of the last four decades are any indication, such draconian steps to avert another 9/11-style event won’t make Americans substantially safer. But they will make them substantially less free.

Liberals understand this when it comes to dealing with global terrorism. Al Gore himself gave a great speech in 2006 lamenting all the constitutional protections that the war on terrorism was claiming and expressed alarm that the executive branch had been conducing warrantless surveillance of telephone calls, emails and other internet communication inside America.

But when it comes to global warming, Gore’s ideological blind spots are more dazzling than the sun. He condemned Trump’s pullout from the Paris agreement as “indefensible” and “reckless.” Likewise, the ACLU, which has been heroically fighting Trump’s travel ban and other constitution-busting moves, bizarrely tweeted that the withdrawal would be a “massive step back for racial justice.”

But the fact of the matter is that a pre-emptive strike against climate change will be no less damaging for justice, racial or otherwise.

“100% certainty is almost always an indication of a cult rather than any sort of actual truth”

Jay Currie looks at the reaction to a Bret Stephens climate article in the New York Times:

On the science side the greatest threats were the inadequacy of the climate models and the advent of the “hiatus”. The models entirely failed to project any circumstances in which temperature ceased to rise when CO2 continued to rise. However the hiatus created exactly that set of conditions for what is now looking like twenty years. (Right this instant, last year’s El Nino, broke the hiatus. However, rapidly cooling post El Nino temperatures look set to bring the hiatus back into play in the next six months to a year.)

The economic side is even worse. It turns out that renewable energy – windmills and solar – costs a fortune and is profoundly unreliable. Governments which went all in for renewables (see Ontario) found their energy prices hockey sticking and the popularity plummeting without, as it turns out, making even a slight impression on the rise of CO2 concentrations.

The economics of climate change and its “mitigation” are a shambles. And it is beginning to dawn on assorted politicians that they might have been railroaded with science which was not quite ready for prime time.

Which makes it all the more imperative for the Nuccitelli and DeSmog blogs of this world to redouble their attacks on even mildly sceptical positions. Had the alarmists been less certain their edifice could have easily withstood a recalibration of the science and a recalculation of the cost/benefits. But they weren’t. They went all in for a position which claimed to know for certain that CO2 was driving world temperature and that there was no other possible cause for an increase or decrease in that temperature.

The problem with that position is that it was premature and very brittle. As lower sensitivity estimates emerge, as other, non-CO2 driven, temperature controls are discovered, consensus climate science becomes more and more embattled. What had looked like a monopoly on political discourse and media comment begins to fray. The advent of Trump and a merry band of climate change skeptics in the regulatory agencies and in Congress, has pretty much killed any forward motion for the climate alarmists in the US. And the US is where this battle will be won or lost. However, the sheer cost of so called “carbon reduction” schemes in the UK, Germany and the rest of Europe has been staggering and has shown next to no actual benefit so scepticism is rising there too. China has both embarked on an embrace of climate change abatement and the construction of dozens of coal fired electrical generation plants every year.

QotD: Science vs media “science”

Filed under: Environment, Media, Science — Tags: , , , — Nicholas @ 01:00

I had someone tell me the other day that I was inconsistent. I was on the side of science (being pro-vaccination) but against science (being pro-fossil fuel use). I have heard this or something like it come up in the vaccination debate a number of times, so a few thoughts:

  1. The commenter is assuming their conclusion. Most people don’t actually look at the science, so saying you are for or against science is their way of saying you are right or wrong.
  2. The Luddites are indeed taking a consistent position here, and both “Food babe” and RFK Jr. represent that position — they ascribe large, unproveable risks to mundane manmade items and totally discount the benefits of these items. This includes vaccines, fossil fuels, GMO foods, cell phones, etc.
  3. I am actually with the science on global warming, it is just what the science says is not well-portrayed in the media. The famous 97% of scientists actually agreed with two propositions: That the world has warmed over the last century and that man has contributed to that warming. The science is pretty clear on these propositions and I agree with them. What I disagree with is that temperature sensitivity to a doubling of CO2 concentrations is catastrophic, on the order of 4 or 5C or higher, as many alarmist believe, driven by absurdly high assumptions of positive feedback in the climate system. But the science is very much in dispute about these feedback assumptions and thus on the amount of warming we should expect in the future — in fact the estimates in scientific papers and the IPCC keep declining each year heading steadily for my position of 1.5C. Also, I dispute that things like recent hurricanes and the California drought can be tied to manmade CO2, and in fact the NOAA and many others have denied that these can be linked. In being skeptical of all these crazy links to global warming (e.g. Obama claims global warming caused his daughter’s asthma attack), I am totally with science. Scientists are not linking these things, talking heads in the media are.

QotD: Science isn’t something you “believe in”

Filed under: Environment, Quotations, Science — Tags: , , — Nicholas @ 01:00

The arguments about global warming too often sound more like theology than science. Oh, the word “science” gets thrown around a great deal, but it’s cited as a sacred authority, not a fallible process that staggers only awkwardly and unevenly toward the truth, with frequent lurches in the wrong direction. I cannot count the number of times someone has told me that they believe in “the science,” as if that were the name of some omniscient god who had delivered us final answers written in stone. For those people, there can be only two categories in the debate: believers and unbelievers. Apostles and heretics.

This is, of course, not how science works, and people who treat it this way are not showing their scientific bona fides; they are violating the very thing in which they profess such deep belief. One does not believe in “science” as an answer; science is a way of asking questions. At any given time, that method produces a lot of ideas, some of which are correct, and many of which are false, in part or in whole.

QotD: The temptation to “shade” the truth toward the consensus

Filed under: Environment, Media, Quotations — Tags: , , — Nicholas @ 01:00

As I am fond of saying, it works like a stock market bubble. There is no need to posit a conspiracy. David Friedman’s view that this is a matter of a build up of many little lies rather than a few big ones is a more realistic as well as a more charitable picture of the mechanism at work.

I am yet more charitable than Professor Friedman. Though I completely agree with him that there are almost certainly many scientists shading their conclusions, it might well be the case that they are not doing so consciously at all. All it would take is for a lot of people with jobs to keep and mortgages to pay each to see which side their bread is buttered when the time comes round to apply for grants. As the American socialist author Upton Sinclair put it, “It is difficult to get a man to understand something, when his salary depends on his not understanding it.” On the unbuttered side of the bread, when a scientist observes that colleagues who raise doubts suffer for it, she would be acting much like the rest of humanity if she, while never aware of feeling fear, somehow finds herself more comfortable out of the intellectual proximity of these pariahs.

In a way the Rosetta scientists had it easy. All they had to do was hit a moving target half a billion kilometres away. Succeed or fail, there is no kidding yourself and no kidding others. Twenty-eight minutes later you and the world will know.

Recalculating the impact of carbon dioxide in the climate models

Filed under: Environment, Science — Tags: , — Nicholas @ 04:00

A few people sent me a link to this article, which may be of interest to those following the ongoing climate debates:

It turns out the UN’s Intergovernmental Panel on Climate Change has over-estimated future global warming by as much as 10 times, [Dr David Evans] says.

“Yes, CO2 has an effect, but it’s about a fifth or tenth of what the IPCC says it is. CO2 is not driving the climate; it caused less than 20 per cent of the global warming in the last few decades”.

Dr Evans says his discovery “ought to change the world”.

“But the political obstacles are massive,” he said.

His discovery explains why none of the climate models used by the IPCC reflect the evidence of recorded temperatures. The models have failed to predict the pause in global warming which has been going on for 18 years and counting.

“The model architecture was wrong,” he says. “Carbon dioxide causes only minor warming. The climate is largely driven by factors outside our control.”

There is another problem with the original climate model, which has been around since 1896.

While climate scientists have been predicting since the 1990s that changes in temperature would follow changes in carbon dioxide, the records over the past half million years show that not to be the case.

So, the new improved climate model shows CO2 is not the culprit in recent global warming. But what is?

Dr Evans has a theory: solar activity. What he calls “albedo modulation”, the waxing and waning of reflected radiation from the Sun, is the likely cause of global warming.

He predicts global temperatures, which have plateaued, will begin to cool significantly, beginning between 2017 and 2021. The cooling will be about 0.3C in the 2020s. Some scientists have even forecast a mini ice age in the 2030s.

“… the carbon tax, like Paris, is worth a Mass”

Filed under: Environment, Politics, Religion — Tags: , , , — Nicholas @ 04:00

At National Review the editors’ response to the Pope’s encyclical on climate change is not warm:

There is an undeniable majesty to the papacy, one that is politically useful to the Left from time to time. The same Western liberals who abominate the Catholic Church as an atavistic relic of more superstitious times, who regard its teachings on abortion and contraception as inhumane and its teachings on sexuality as a hate crime today are celebrating Pope Francis’s global-warming encyclical, Laudato Si’, as a moral mandate for their cause. So much for that seamless garment.

It may be that the carbon tax, like Paris, is worth a Mass.

The main argument of the encyclical will be no surprise to those familiar with Pope Francis’s characteristic line of thought, which combines an admirable and proper concern for the condition of the world’s poor with a crude and backward understanding of economics and politics both. Any number of straw men go up in flames in this rhetorical auto-da-fé, as the pope frames his concern in tendentious economic terms: “By itself, the market cannot guarantee integral human development and social inclusion.” We are familiar with no free-market thinker, even the most extreme, who believes that “by itself, the market can guarantee integral human development.” There are any number of other players in social life — the family, civil society, the large and durable institution of which the pope is the chief executive — that contribute to human flourishing. The pope is here taking a side in a conflict that, so far as we can tell, does not exist.

QotD: Political beliefs and reality

Filed under: Environment, Politics, Quotations — Tags: , , — Nicholas @ 01:00

Political beliefs affect what one wants to be true. People are pretty good at persuading themselves that what they want to be true is true.

That works in both directions in the context of arguments about climate change. People who share my political views are suspicious of government regulation, CAGW (Catastrophic Anthropogenic Global Warming) provides an argument in favor of more government regulation and is used as such an argument at present, so we naturally want to look for arguments against CAGW.

On the other side, it’s my experience that people who think global warming is a terrible problem that must be dealt with are also, by some odd coincidence, people who think the things that need to be done to deal with it are things most of which ought to be done anyway, that the real cost is low or negative. They are likely to put that point in terms of creating a cleaner, more sustainable world. From their standpoint, CAGW provides arguments to persuade people to do things they want done, so they naturally want to look for arguments in favor of CAGW.

To some, it’s worse to be a “lukewarmer” than a full-blown “global warming denier”

Filed under: Environment, Media, Science — Tags: , , — Nicholas @ 04:00

Matt Ridley on the trouble with only agreeing somewhat with the “scientific” “consensus”:

I am a climate lukewarmer. That means I think recent global warming is real, mostly man-made and will continue but I no longer think it is likely to be dangerous and I think its slow and erratic progress so far is what we should expect in the future. That last year was the warmest yet, in some data sets, but only by a smidgen more than 2005, is precisely in line with such lukewarm thinking.

This view annoys some sceptics who think all climate change is natural or imaginary, but it is even more infuriating to most publicly funded scientists and politicians, who insist climate change is a big risk. My middle-of-the-road position is considered not just wrong, but disgraceful, shameful, verging on scandalous. I am subjected to torrents of online abuse for holding it, very little of it from sceptics.

I was even kept off the shortlist for a part-time, unpaid public-sector appointment in a field unrelated to climate because of having this view, or so the headhunter thought. In the climate debate, paying obeisance to climate scaremongering is about as mandatory for a public appointment, or public funding, as being a Protestant was in 18th-century England.

Kind friends send me news almost weekly of whole blog posts devoted to nothing but analysing my intellectual and personal inadequacies, always in relation to my views on climate. Writing about climate change is a small part of my life but, to judge by some of the stuff that gets written about me, writing about me is a large part of the life of some of the more obsessive climate commentators. It’s all a bit strange. Why is this debate so fractious?

Rather than attack my arguments, my critics like to attack my motives. I stand accused of “wanting” climate change to be mild because I support free markets or because I receive income indirectly from the mining of coal in Northumberland. Two surface coal mines (which I do not own), operating without subsidies, do indeed dig coal partly from land that I own. They pay me a fee, as I have repeatedly declared in speeches, books and articles.

The great and the good gather at Davos

Filed under: Economics, Politics — Tags: , , , , — Nicholas @ 03:00

And Monty calls ’em exactly what they are:

Luckily, all is not lost. Our moral and ethical betters have gathered in Davos to light their cigars with hundred-dollar bills while mocking the tubercular bootblack who’s been pressed into service to keep their shoes looking spiffy while they chat and laugh and eat lobster canapes. Oh, wait, I read that wrong, sorry. They’re in Davos to discuss the pressing problem of Global Warming(tm). Because they’re so concerned about Global Warming(tm) that they felt compelled to fly their private jets to an upscale enclave in the Swiss Alps to talk about it. While making fun of the tubercular bootblack who’s spit-shining their wingtips.

Don’t get me wrong – I’m a big believer in ostentatious displays of wealth. If I had the money, I’d build a hundred-foot-high statue of myself made out of pure platinum and then hire homeless people to worship at it for no fewer than eight hours per day. (I’d pay them a fair wage, though. What’s the going rate for abject obeisance to a living God? I’ll have to look it up.) But this Davos thing is just…rank. It’s a collection of rich fart-sniffers who want to congratulate each other on how socially conscious they are, and how much they care about the Little People. (Except the tubercular bootblack, whom they often kick with their rich-guy shoes.)

Placebo effect so powerful that it can influence the climate

Filed under: Britain, Environment, Humour — Tags: , , , — Nicholas @ 07:34

JoNova on the newly discovered Global Placebo Effect:

Matt Ridley was questioning Baroness Sandip Verma at the House of Lords this week. He pointed out to the peers that even the IPCC admits there is “hiatus” that modelers can’t explain. Verma responded: “‘It [global warming] may have slowed down, but that is a good thing. It could well be that some of the measures we are taking today is helping that to occur.’” [Source — Dailymail]

Verma raises the intriguing possibility that windmills and solar panels that were built after 2005 have managed to keep global temperatures constant starting from ten years before they were constructed.

What’s even more remarkable is that none of these projects or activities have reduced global CO2 levels. It follows then, that the mere thought of building windmills is enough to change the weather.

Furthermore, it’s well known that more expensive placebo’s are more effective. Hence the final-final copy of the latest IPCC report — issued on Friday after the leak, the draft, and the redraft — will explain that they are 95% certain that if we spend $2 billion dollars a day on renewable energy (instead of just $1 billion) there will be no more category five storms, seas will stop rising, and goats will stop shrinking.

The BBC losing its balance over climate reporting

Filed under: Britain, Environment, Media — Tags: , , — Nicholas @ 09:16

Matt Ridley on the BBC’s loss of balance:

The BBC’s behaviour grows ever more bizarre. Committed by charter to balanced reporting, it has now decided formally that it was wrong to allow balance in a debate between rival guesses about the future. In rebuking itself for having had the gall to interview Nigel Lawson on the Today programme about climate change earlier this year, it issued a statement containing this gem: “Lord Lawson’s views are not supported by the evidence from computer modelling and scientific research.”

The evidence from computer modelling? The phrase is an oxymoron. A model cannot, by definition, provide evidence: it can provide a prediction to test against real evidence. In the debate in question, Lord Lawson said two things: it was not possible to attribute last winter’s heavy rain to climate change with any certainty, and the global surface temperature has not warmed in the past 15 to 17 years. He was right about both, as his debate opponent, Sir Brian Hoskins, confirmed.

As for the models, here is what Dr Vicky Pope of the Met Office said in 2007 about what their models predicted: “By 2014, we’re predicting that we’ll be 0.3 degrees warmer than 2004. Now just to put that into context, the warming over the past century and a half has only been 0.7 degrees, globally … So 0.3 degrees, over the next ten years, is pretty significant … These are very strong statements about what will happen over the next ten years.”

In fact, global surface temperature, far from accelerating upwards, has cooled slightly in the ten years since 2004 on most measures. The Met Office model was out by a country mile. But the BBC thinks that it was wrong even to allow somebody to challenge the models, even somebody who has written a bestselling book on climate policy, held one of the highest offices of state and founded a think-tank devoted to climate change policy. The BBC regrets even staging a live debate between him and somebody who disagrees with him, in which he was robustly challenged by the excellent Justin Webb (of these pages).

And why, pray, does the BBC think this? Because it had a complaint from a man it coyly describes as a “low-energy expert”, Mr Chit Chong, who accused Lord Lawson of saying on the programme that climate change was “all a conspiracy”.

Lawson said nothing of the kind, as a transcript shows. Mr Chong’s own curriculum vitae boasts that he “has been active in the Green party for 25 years and was the first Green councillor to be elected in London”, and that he “has a draught-proofing and insulation business in Dorset and also works as an environmental consultant”.

So let’s recap. On the inaccurate word of an activist politician with a vested financial and party interest, the BBC has decided that henceforth nobody must be allowed to criticise predictions of the future on which costly policies are based.

Emperor penguins at risk

Filed under: Environment, Science — Tags: , , — Nicholas @ 08:15

A somewhat confusing report from BBC News says that due to warming in the Antarctic, there is now record ice extent, which means Emperor penguins have to travel much further to find open water. The warming (which has created all the extra ice) is expected to get much worse and is predicted to cut the penguin population by up to a third by the end of the century.

The main threat to the penguins comes from changes to sea-ice cover in the Antarctic, which will affect their breeding and feeding.

Dynamics will differ between penguin colonies, but all are expected to be in decline by the end of the century.

Details are published in Nature Climate Change journal.

The US, British and Dutch researchers urge governments to list the birds as endangered. Such a listing could impose restrictions on tourism and fishing.

The team, led by Stephanie Jenouvrier of the Woods Hole Oceanographic Institution, said the global population of emperor penguins would probably decline by between 19 and 33% from current levels.


“There is a goldilocks point for ice and emperor penguins,” Phil Trathan, an expert at the British Antarctic Survey (Bas), told Reuters.

Mr Trathan said it was unclear if the ungainly birds could adapt by climbing on to land or higher ice. Four emperor penguin colonies had recently been found on ice shelves, above sea level where glaciers spill off the land.

Satellite measurements of Antarctic sea-ice extent show winter coverage to be at record levels. However, climate computer modelling expects this trend to be reversed in the future, as conditions in the Antarctic warm.

Anyone else remember this French TV commercial?

Update, 2 July: Blinded by Beliefs: The Straight Poop on Emperor Penguins.

Two recent press releases concerning the Emperor Penguin’s fate illustrate contrasting forces that will either advance or suppress trustworthy conservation science. The first study reminds me of Mark Twain’s quip, “Education consists mainly in what we have unlearned.” Embodying that truism is a paper by lead author Dr. Michelle LaRue who reports new advances in reading the Emperor Penguin’s fecal stains on Antarctic sea ice that are visible in satellite pictures. Two years ago the fecal stain method identified several large, hitherto unknown colonies and nearly doubled our estimate of the world’s Emperor Penguins. That didn’t mean climate change had necessarily increased penguin numbers, but a larger more robust population meant Emperor Penguins were far more resilient to any form of change.
