Climate change policies – “a massive conservative blind spot … matched by liberals’ tunnel vision”

Filed under: Environment, Politics, USA — Tags: , , , — Nicholas @ 07:35

Shikha Dalmia on the real reason the right fights against massive government action to fight climate change:

The decibel level in our national debate about global temperature went up several notches this week. The White House noisily released a report full of dire claims about the havoc manmade global warming is causing in America — and Republicans, equally noisily, denounced this as “liberal gloom and doom.”

The left has a deep ideological need to hype this issue, and the right to minimize it. And despite the deafening political noise on what ought to be a scientific matter, Americans must not be tempted to reach for their earplugs in disgust. After all, these ideological wars are how democracies sort out their differences.

[…]

The right’s chief commitment (which I share) is to free enterprise, property rights, and limited government that it sees as core to human progress. So when the market or other activities of individuals harm third parties or the environment, they look for solutions in these principles.

If overgrazing threatens a pasture, to use a classic example, the right’s answer is not top-down government diktats to ban or ration use. Rather, it is to divvy up the pasture, giving ownership to farmers — or privatizing the commons. The idea is that what individuals own, they protect; what they don’t, they abuse.

But there is no pure free market or property rights solution to global warming. There is no practical way to privatize the Earth’s atmosphere or divvy up pollution rights among the world’s seven billion inhabitants in 193 countries. This creates a planet-sized opening for the expansion of the regulatory state. Hence, right-wingers have an inherent need to resist the gloomy global warming narrative.

This is a massive conservative blind spot. But it is, in many ways, matched by liberals’ tunnel vision.

It is no secret that liberal commitment is less to promoting individual liberty and more to curbing capitalistic greed, which the left views as the great enemy of social justice and equality. At first blush, environmentalism and egalitarianism appear in conflict given that the environment is something of a luxury good that rich folks generally care about more than the poor.

Indeed, this conflict is why the 1960s New Left, driven primarily by humanistic concerns such as eradicating poverty and eliminating racism, shunned the emerging environmental movement for over a decade, according to University of Wisconsin’s Keith M. Woodhouse. Many in the New Left condemned the first Earth Day in 1970 as “the white liberal’s cop out” and believed that a preoccupation with overpopulation, for example, was “racist hysteria.”

David Harsanyi – The climate change debate is over

Filed under: Environment, Media, Politics — Tags: , , , — Nicholas @ 09:45

At The Federalist, David Harsanyi says the debate is over and the environmentalists have lost:

The truth is that even if Americans believed that scientists had seer-like abilities and the models were accurate, they would still be hesitant to embrace 19th century technology because they simply can’t afford it. Though I suspect most people instinctively understand that the environment has gotten better by almost every measure over the past 40 years, climate change activists ignore the massive benefits of carbon emitting fuels and technology that helps us become more productive and increasingly efficient.

Now, you can try and guilt trip everyone into compliance. You can batter them with distressing hypothetical scenarios. You can “educate” them on the issue from kindergarten onward, you can mainstream an array of Luddite ideas, you can browbeat society so they never utter a word of skepticism, but we still want to drive our cars everywhere. This is probably why over-the-top warnings and preposterous analogies have hit peak levels of absurdity.

And that’s saying something. Dr. John Holdren, Obama’s Science Czar, who was on media call for the National Climate Assessment release, once predicted global warming could cause the deaths of 1 billion people by 2020 and that sea levels would rise by 13 feet by the end of the century (not to mention, he co-authored a book with Paul Ehrlich in which he explained that “population-control laws, even including laws requiring compulsory abortion, could be sustained under the existing Constitution…”). Malthusians never admit they’re wrong, they simply push the apocalypse out a couple of decades. I just don’t think people believe them anymore.

Yes, when asked, Americans perfunctorily tell pollsters that climate change matters to them. A recent Pew Research Center poll found that 40 percent of Americans believe that climate change is a major threat. A Gallup poll survey found that around third of Americans personally worry about climate change. But when they’re not asked specifically about global warming, voters never bring the topic up. They’re most important concerns are the economy, jobs and debt. Though there is always strong support for the abstract idea of environmental regulation and “clean energy,” but when it comes some concrete policy it is nearly always unpopular. Few people want to stop the Keystone XL Pipeline. Few people support new emissions regulations. And I doubt another scaremongery study will change that reality.

Climate change and positive effects

Filed under: Economics, Environment, Media, Science — Tags: , — Nicholas @ 08:30

Matt Ridley explains that according to the experts, it’s believed that ongoing climate change actually provides net benefits for most of this century:

Climate change has done more good than harm so far and is likely to continue doing so for most of this century. This is not some barmy, right-wing fantasy; it is the consensus of expert opinion. Yet almost nobody seems to know this. Whenever I make the point in public, I am told by those who are paid to insult anybody who departs from climate alarm that I have got it embarrassingly wrong, don’t know what I am talking about, must be referring to Britain only, rather than the world as a whole, and so forth.

At first, I thought this was just their usual bluster. But then I realised that they are genuinely unaware. Good news is no news, which is why the mainstream media largely ignores all studies showing net benefits of climate change. And academics have not exactly been keen to push such analysis forward. So here follows, for possibly the first time in history, an entire article in the national press on the net benefits of climate change.

There are many likely effects of climate change: positive and negative, economic and ecological, humanitarian and financial. And if you aggregate them all, the overall effect is positive today — and likely to stay positive until around 2080. That was the conclusion of Professor Richard Tol of Sussex University after he reviewed 14 different studies [PDF] of the effects of future climate trends.

To be precise, Prof Tol calculated that climate change would be beneficial up to 2.2˚C of warming from 2009 (when he wrote his paper). This means approximately 3˚C from pre-industrial levels, since about 0.8˚C of warming has happened in the last 150 years. The latest estimates of climate sensitivity suggest that such temperatures may not be reached till the end of the century — if at all. The Intergovernmental Panel on Climate Change, whose reports define the consensis, is sticking to older assumptions, however, which would mean net benefits till about 2080. Either way, it’s a long way off.

[…]

You can choose not to believe the studies Prof Tol has collated. Or you can say the net benefit is small (which it is), you can argue that the benefits have accrued more to rich countries than poor countries (which is true) or you can emphasise that after 2080 climate change would probably do net harm to the world (which may also be true). You can even say you do not trust the models involved (though they have proved more reliable than the temperature models). But what you cannot do is deny that this is the current consensus. If you wish to accept the consensus on temperature models, then you should accept the consensus on economic benefit.

Losing a debate? Demand that your opponents be locked up!

Filed under: Environment, Italy, Media, Politics, USA — Tags: , , , — Nicholas @ 08:57

Not, I’m afraid, an April Fool’s Day story:

Finally, someone has come up with a way to settle the debate over climate change: Put the people on the wrong side of the argument in cages.

A writer for the website Gawker recently penned a self-described “rant” on the pressing need to arrest, charge and imprison people who “deny” global warming. In fairness, Adam Weinstein doesn’t want mass arrests (besides, in a country where only 44% of Americans say there is “solid evidence” of global warming and it’s mostly due to human activity, you can’t round up every dissenter). Fact-checking scientists are spared. So is “the man on the street who thinks Rush Limbaugh is right. … You all know that man. That man is an idiot. He is too stupid to do anything other than choke the earth’s atmosphere a little more with his Mr. Pibb burps and his F-150’s gassy exhaust.”

But Weinstein’s magnanimity ends there. Someone must pay. Weinstein suggests the government simply try the troublemakers and spokespeople. You know, the usual suspects. People like Limbaugh himself as well as ringleaders of political organizations and businesses that refuse to toe the line. “Those malcontents must be punished and stopped.”

Weinstein says that this “is an argument that’s just being discussed seriously in some circles.” He credits Rochester Institute of Technology philosophy professor Lawrence Torcello for getting the ball rolling. Last month, Torcello argued that America should follow Italy’s lead. In 2009, six seismologists were convicted of poorly communicating the risks of a major earthquake. When one struck, the scientists were sentenced to six years in jail for downplaying the risks. Torcello and Weinstein want a similar approach for climate change.

This is a great standard for free speech in America. Let’s just agree that the First Amendment reads, “Nothing in this clause shall be considered binding if it contradicts legal practices in the Abruzzo region of Italy.”

The truth is this isn’t as new an outlook as Weinstein suggests. For instance, in 2009, New York Times columnist Paul Krugman insisted that “deniers” in Congress who opposed the Waxman-Markey climate change bill were committing “treason” while explaining their opposition on the House floor. (That same year, Krugman’s fellow Timesman Thomas Friedman wrote that China’s authoritarian system was preferable to ours, in part, because it lets “enlightened” leaders deal with climate change.)

Nate Silver … in the shark tank

Filed under: Environment, Media — Tags: , , , — Nicholas @ 10:24

Statistician-to-the-stars Nate Silver can shrug off attacks from Republicans over his 2012 electoral forecast or from Democrats unhappy with his latest forecast for the 2014 mid-terms, but he’s finding himself under attack from an unexpected quarter right now:

Ever wondered how it would feel to be dropped from a helicopter into a swirling mass of crazed, genetically modified oceanic whitetip sharks in the middle of a USS-Indianapolis-style feeding frenzy?

Just ask Nate Silver. He’s been living the nightmare all week – ever since he had the temerity to appoint a half-way skeptical scientist as resident climate expert at his “data-driven” journalism site, FiveThirtyEight.

Silver has confessed to The Daily Show that he can handle the attacks from Paul Krugman (“frivolous”), from his ex-New York Times colleagues, and from Democrats disappointed with his Senate forecasts. But what has truly spooked this otherwise fearless seeker-after-truth, apparently, is the self-righteous rage from the True Believers in Al Gore’s Church of Climate Change.

“We don’t pay that much attention to what media critics say, but that was a piece where we had 80 percent of our commenters weigh in negatively, so we’re commissioning a rebuttal to that piece,” said Silver. “We listen to the people who actually give us legs.”

The piece in question was the debut by his resident climate expert, Roger Pielke, Jr., arguing that there was no evidence to support claims by alarmists that “extreme weather events” are on the increase and doing more damage than ever before. Pielke himself is a “luke-warmer” – that is, he believes that mankind is contributing to global warming but is not yet convinced that this contribution will be catastrophic. But neither his scientific bona fides (he was Director of the Center for Science and Technology Policy Research at the University of Colorado Boulder) nor his measured, fact-based delivery were enough to satisfy the ravening green-lust of FiveThirtyEight’s mainly liberal readership.

David Friedman responds to William Nordhaus on global warming costs

Filed under: Economics, Environment — Tags: , , — Nicholas @ 09:40

At his blog, David Friedman links to a recent New York Review of Books article by William Nordhaus (itself a response to a Wall Street Journal article) which argues for economic action to address the impact of global warming:

His final, and possibly most important point, is based on his own research, which he complains that the WSJ article is misrepresenting. He starts with a correct point—that it is the difference between benefit and cost, not the ratio, that matters. He goes on to summarize his conclusion:

    My research shows that there are indeed substantial net benefits from acting now rather than waiting fifty years. A look at Table 5-1 in my study A Question of Balance (2008) shows that the cost of waiting fifty years to begin reducing CO2 emissions is $2.3 trillion in 2005 prices. If we bring that number to today’s economy and prices, the loss from waiting is $4.1 trillion. Wars have been started over smaller sums.

What he does not mention is that his $4.1 trillion is a cost summed over the entire globe and the rest of the century. Put in annual terms, that come to about $48 billion a year, a less impressive number. Current world GNP is about $85 trillion/year. So the net cost of waiting, on Nordhaus’s own numbers, is about one twentieth of one percent of world GNP. Not precisely a catastrophe.

I suggest a simple experiment. Let Nordhaus write a piece explicitly arguing that the net cost of waiting is about .06% of world GNP and see whether it is more popular with the supporters or the critics of his position. I predict that at least one supporter will accuse him of having sold out to big oil.

[…]

The future is very much too uncertain to have confidence in estimates of what will be happening fifty years from now — for an extended demonstration, see my Future Imperfect. If we follow Nordhaus’s current advice and tax carbon now in order to slow warming, it may turn out that the costs were unnecessary or even counterproductive. We may be spending money in order to make ourselves poorer, not richer.

I conclude, on the basis of Nordhaus’s own figures and without taking account of my past criticism of his calculations, that he has his conclusion backwards. The sensible strategy is to take no actions whose justification depends on the belief that increased CO2 produces large net costs until we have considerably better reason than we now do to believe it.

Carl Sagan and when warnings about a new ice age switched to global warming instead

Filed under: Environment, Media, Science — Tags: , , — Nicholas @ 09:44

As a youngster, Robert Tracinski was a huge fan of Carl Sagan’s Cosmos TV series. It was a formative experience for him, yet he found that Sagan’s concerns about global warming were not convincing … because those warnings were actually antithetical to his larger message:

It might seem strange to say it, but I am a global warming skeptic because of Carl Sagan.

This might seem strange because Sagan was an early promoter of the theory that man-made emissions of carbon dioxide are going to fry the globe. But it’s not so strange when you consider the larger message that made Sagan famous.

As with many people my age, Sagan’s 1980 series Cosmos, which aired on public television when I was eleven years old, was my introduction to science, and it changed my life. Cosmos shared the latest developments in the sciences of evolution, astronomy, and astrophysics, but its real heart was Sagan’s overview of the history of science and the distinctive ethos behind the scientific method. Sagan returned again and again to one central theme: that the first rule of science is to follow the evidence wherever it leads, regardless of one’s wishes or preconceptions. He spoke eloquently about the Ancient Greek Pythagoreans and their attempt to suppress the facts about “irrational numbers” that didn’t fit their theory. And he spoke admiringly about the 17th-century astronomer Johannes Kepler, who started out pursuing a theory in which the planets move in circular orbits reflecting the ratios of the perfect Pythagorean solids — and ended up being driven by the evidence to reject this theory and discover completely new laws of planetary motion.

I didn’t end up becoming a scientist, but I absorbed Sagan’s basic lesson and have tried my best to adhere to it in my own field: follow the evidence wherever it leads.

But this can be a difficult rule to follow. It is easy to spot the unexamined assumptions of others, but harder to root out your own prejudices. A few years ago, while watching Cosmos again for the first time in 25 years, I was reminded that Sagan did not always practice what he preached, and his error sheds light on the global warming theory’s original sin against science. It is a sin that has only gotten worse and which explains the scandalous state of today’s debate over global warming.

[…]

This is a bit of a cultural time capsule, preserving the precise moment at which scientific alarmists were switching from warning about a new ice age, in the 1970s, to warning about runaway warming.

Antarctic climate researchers still not home-free

Filed under: Australia, Environment, Media, Science — Tags: , , , — Nicholas @ 11:59

AntarcticaRemember the story about the Australian climate researchers trapped in the Antarctic ice? The good news from a few days back — that all the passengers of the MS Akademik Shokalskiy (including researchers, tourists, and journalists, but not the crew) had been successfully transferred to the Australian icebreaker Aurora Australis is now overshadowed because the Chinese icebreaker Xue Long which also responded to the SOS call is now itself also trapped in the ice:

The saga just keeps going. The Chinese Icebreaker is now also stuck, and has asked for help so the Aurora Australis with 52 extra passengers rescued from the Russian Charter boat have to stay nearby to help. Twenty two Russian sailors are still trapped on board the Russian boat — the Akademik Sholaskiy. Plus other scientists in Antarctica still don’t have their equipment. Costs for everyone involved are continuing to rise.

In The Australian, Graham Lloyd‘s paywalled article begins with this:

TAXPAYERS will foot a $400,000 bill for the rescue of a group of climate scientists, tourists and journalists from a stranded Russian research vessel — an operation that has blown the contingency budget of Australia’s Antarctic program and disrupted its scientific work. The Antarctic Division in Hobart said it was revising plans and considering airlifting urgently needed scientific equipment that could not be unloaded from Aurora Australis before the ship was diverted from the Casey base to rescue the novice ice explorers just before Christmas.

The Sydney Morning Herald posted this short video earlier in the week, before the Aurora Australis had gotten close enough to take on the passengers from the Akademik Sholaskiy:

Update: The head of French antarctic research is unhappy with the tourists’ disruption to actual science work:

The head of France’s polar science institute voiced fury on Friday at the misadventures of a Russian ship trapped in Antarctic ice, deriding what he called a tourists’ trip that had diverted resources from real science.

In an interview with AFP, Yves Frenot, director of the French Polar Institute, said he had no issue at all with rescuing those aboard the stricken vessel.

But, he said, the trip itself was a “pseudo-scientific expedition” that, because it had run into difficulties, had drained resources from the French, Chinese and Australian scientific missions in Antarctica. “There’s no reason to place Antarctica off-limits and to keep it just for scientists, but this tourism has to be monitored and regulated so that operators can be sure of getting help if need be,” he said.

The hazards facing the Australasian Antarctic Expedition

Filed under: Environment, Media, Science — Tags: , , — Nicholas @ 12:25

AntarcticaThe Australasian Antarctic Expedition (AAE) has run into far harsher sea and ice conditions than they’d banked on, and it raises questions about the scientific validity of the expedition:

The purpose of the AAE expedition was to take a science team of 36 women and men south to discover just how much change has taken place at Mawson Station over 100 years. The expedition was also intended to replicate the original AAE led by explorer Sir Douglas Mawson a century ago, in 1913. The new expedition was to be led by Prof. Chris Turney, a publicity-hungry professor of climate change at Australia’s University of New South Wales.

Antarctic-AAE

Also the expedition was designed to generate lots of publicity. Along the scientists and ship’s crew were 4 journalists from leading media outlets who would feed news regularly, and later report extensively on the results and findings. All this in turn would bring loads of attention to a region that is said to be threatened by global warming. The AAE’s donation website even states that the expedition’s purpose is to collect data and that the findings are “to reach the public and policy makers as soon as possible“.

But expeditions of this type are expensive and funding is not always easy to come by. Costs can run in the millions as special equipment is needed to handle the extremely harsh conditions of the South Pole. Downplaying the conditions to justify cost-cutting by using lower grade equipment rapidly jeopardizes safety.

Inadequate, bargain-price research vessel

The first error expedition leaders made was under-estimating the prevailing sea ice conditions at Mawson Station, their destination. The scientists seemed to be convinced that Antarctica was a warmer place today than it had been 100 years earlier, and thus perhaps they could expect less sea ice there. This in turn would allow them to charter a lighter, cheaper vessel.

This seems to be the case judging by their choice of seafaring vessel. They chartered a Russian vessel MS Akademik Shokalskiy, an ice-strengthened ship built in Finland in 1982. According to Wikipedia the ship has two passenger decks, with dining rooms, a bar, a library, and a sauna, and accommodates 54 passengers and a crew of up to 30. Though it is ice-reinforced, it is not an ice-breaker. This is a rather surprising selection for an expedition to Antarctica, especially in view that the AAE website itself expected to travel through areas that even icebreakers at times are unable to penetrate, as we are now vividly witnessing. Perhaps the price for chartering the Russian vessel was too good to pass up.

Luring naïve tourists as a source of cash

What made the expedition even more dubious is that Turney and his team brought on paying tourists in what appears to have been an attempt to help defray the expedition’s costs and to be a source of cheap labor. According to the AAE website, the expedition was costed at US$1.5 million, which included the charter of the Akademik Shokalskiy to access the remote locations. “The site berths on board are available for purchase.” Prices start at $8000!

The expedition brought with it 4 journalists, 26 paying tourists.

Update, 2 January: An editorial in The Australian after news came out that all of the 52 passengers had been rescued from the ice-bound Akademik Shokalskiy:

YOU have to feel a touch of sympathy for the global warming scientists, journalists and other hangers-on aboard the Russian ship stuck in impenetrable ice in Antarctica, the mission they so confidently embarked on to establish solid evidence of melting ice caps resulting from climate change embarrassingly abandoned because the ice is, in fact, so impossibly thick.

[…]

Professor Turney’s expedition was supposed to repeat scientific investigations made by Douglas Mawson a century ago and to compare then and now. Not unreasonably, it has been pointed out Mawson’s ship was never icebound. Sea ice has been steadily increasing, despite the Intergovernmental Panel on Climate Change’s gloomy forecasts. Had the expedition found the slightest evidence to confirm its expectation of melting ice caps and thin ice, a major new scare about the plight of the planet would have followed. As they are transferred to sanctuary aboard the icebreaker Aurora Australis, Professor Turney and his fellow evacuees must accept the embarrassing failure of their mission shows how uncertain the science of climate change really is. They cannot reasonably do otherwise.

The 22 crew members will stay on board the vessel until it can be released from the ice (or until another rescue effort needs to be mounted).

Scientific facts and theories

Filed under: Environment, Science, Space — Tags: , , , , — Nicholas @ 10:32

Christopher Taylor wants to help you avoid mis-using the word “fact” when you’re talking about “theories”:

These days, criticizing or questioning statements on science can get you called an idiot or even a heretic; science has become a matter of religious faith for some. If a scientist said it, they believe it, and that’s that. Yet the very nature about science is not to be an authoritative voice, but a method of inquiry; science is about asking questions and wondering if something is valid and factual, not a system of producing absolute statements of unquestioned truth.

It is true that people need that source of truth and it is true that we’re all inescapably religious creatures, so that will find an outlet somewhere. Science just isn’t the proper outlet for it.

[…]

The problem is that there’s no way to test or confirm this theory [plate tectonics]. You can make a model and see it work, you can check out types of rock and examine fault lines, and you can make measurements, but that’s only going to tell you small portions of information in very limited time frames. Because the earth is so huge, and because there are so very many different pressures and influences on everything on a planet, you can’t be sure without observation over time.

And since the theory posits that it would take millions of years to really demonstrate this to be true, humanity cannot test it enough to be certain. So all we’re left with is a scientific theory: a functional method of interpreting data. In other words, it cannot be properly or accurately describe as fact.

This is true about other areas. The word “fact” is thrown around so casually with science and is defended angrily by people who really ought to know better. Cosmology does this a lot. Its a fact that the universe is expanding from an unknown central explosive point (although there is a fair amount of data that’s throwing this into question). We can’t know because we can’t have enough data and there hasn’t been long enough to really test this.

Michael Crichton’s criticism of global warming was along these lines. He didn’t deny anything, he just said its too big and complex a system that we understand far too little about to even attempt to make any absolute or authoritative statements about it. Science has gotten us far beyond our ability to properly measure or interpret the data at hand, but some still keep trying to make absolute statements anyway.

[…]

And that’s the heart of a scientific theory. It isn’t like a geometric theorem (a statement or formula that can be deduced from the axioms of a formal system by means of its rules of inference), or a theory that Sherlock Holmes might develop (a proposed explanation whose status is still conjectural). A scientific theory is a system of interpreting data (a coherent group of general propositions used as principles of explanation for a class of phenomena). It’s a step beyond a hypothesis, which is simply speculation or a guess, but is not proven fact.

Confusing theory with fact is really not excusable for an educated person, but some theories are so wedded to worldviews and hopes that they become a matter of argument and even rage. Questioning that theory means you’re an idiot, uneducated, worthless. If you doubt this theory, you’re clearly someone who is wrong about everything and should be totally ignored in life, even showered with contempt.

For all its rich vocabulary, English fails to correctly differentiate among the various uses of the word “theory”, which allows propagandists and outright frauds to confuse the issues and obscure the difference between what science can say about an issue and what believers desperately want to be true.

Climate models, trust, and spin

Filed under: Environment, Media — Tags: , , — Nicholas @ 08:58

In Reason, Ronald Bailey asks whether we can trust the IPCC’s climate models:

On Monday, the U.N.’s Intergovernmental Panel on Climate Change (IPCC) released the final draft of Climate Change 2013: The Physical Sciences Basis. The report’s Summary for Policymakers flatly states: “Warming of the climate system is unequivocal, and since the 1950s, many of the observed changes are unprecedented over decades to millennia. The atmosphere and ocean have warmed, the amounts of snow and ice have diminished, sea level has risen, and the concentrations of greenhouse gases have increased.” Pretty much everyone concerned with this issue agrees that those are the facts. But what is causing the planet to warm up? Here is where it gets interesting.

[…]

The IPCC report acknowledges that almost all of the “historical simulations do not reproduce the observed recent warming hiatus.” Not to worry, it assures us; 15-year pauses just happen, and you can’t really expect the models to simulate these kind of random natural fluctuations in the climate. Once this little slow-down passes, “It is more likely than not that internal climate variability in the near-term will enhance and not counteract the surface warming expected to arise from the increasing anthropogenic forcing.” In other words, when the warm-up resumes it will soar.

John Christy, a climatologist at the University of Alabama in Huntsville, has come to a different conclusion. Christy compared the outputs of 73 climate models for the tropical troposphere used by the IPCC in its latest report with satellite and weather balloon temperature trends since 1979 until 2030. “The tropics is so important because that is where models show the clearest and most distinct signal of greenhouse warming — so that is where the comparison should be made (rather than say for temperatures in North Dakota),” Christy explains in an email. “Plus, the key cloud and water vapor feedback processes occur in the tropics.” When it comes to simulating the atmospheric temperature trends of the past 35 years, Christy found, all of the IPCC models are running hotter than the actual climate.

[…]

Average of model results compared with temperature trends

Average of model results compared with temperature trends

To defend himself against any accusations of cherry-picking his data, Christy notes that his “comparisons start in 1979, so these are 35-year time series comparisons” — rather longer than the 15-year periods whose importance the IPCC disputes.

Why the discrepancy between the IPCC and Christy results? As Georgia Tech climatologist Judith Curry notes, data don’t speak for themselves; researchers have to put them into a context. And your choice of context — say, the year you choose to begin with — can influence your conclusions considerably. While there may be nothing technically wrong with the way the IPCC chose to display the comparison between model data and observation data, “Curry observes, it will mislead the public to infer that climate models are better than we thought.” She adds, “What is wrong is the failure of the IPCC to note the failure of nearly all climate model simulations to reproduce a pause of 15+ years.”

Harper and climate change … spending

Filed under: Cancon, Environment, Government — Tags: , , , , — Nicholas @ 10:07

David Akin points out that all the major federal parties believe the same thing about climate change, except that the Tories are the ones who’ve been chucking around the money on climate change programs:

The simple fact of Canadian politics here is that, if you do not believe in climate change, there is no federal political party that shares your view. There almost was one in Alberta in its last provincial election but, boy, did that idea get shouted down.

But back to what [former environment minister Peter] Kent said to me in that interview:

“There is no question that since the Industrial Revolution there have been anthropogenic, man-made effects on our global climate. The argument continues in the scientific community how much is evolution and how much is man-made but there is certainly something we can do.”

So what is the something that the Harper government has been doing? Well, truth be told, the Harper Conservatives, like the Martin and Chretien Liberals before them, have not been doing very much. None of them, in fact, got the job done. Which might, come to think of it, be a good reason — if climate change is the only thing you’re voting on — to consider choosing the NDP or the Greens next time around. Not to say they’d actually get it done but it’s pretty clear the other two parties, while they talk a good game, just don’t have the political stomach for the job. Those New Democrats brought us universal health care. Maybe they can fix the environment, too.

Still, that doesn’t mean Conservatives aren’t prepared to spend hundreds of millions of dollars — billions even — on a problem they are accused of not admitting even exists. Take biofuels, for example. Early on, the Harper government got the idea that if corn- or plant-based ethanol displaced enough fossil fuels, we’d easily roll back greenhouse gas emissions. Apparently no one bothered to point out that there is serious doubt that corn-based ethanol is actually a lower-emission alternative to fossil fuels but why complicate things? Ethanol is a good, solid, job-creating green story!

In the long run, the subsidies and outright gifts of government money to green-ish sounding companies will likely be the only reminders of the great global warming panic of the last decade. Certainly little or no actual environmental improvements will be traced to the billions of dollars doled out to cronies under this government.

Statistical fail for political axe-grinding

Filed under: Environment, Media, Politics, USA — Tags: , , — Nicholas @ 11:29

Coyote Blog views with alarm a recent article in Rolling Stone which abuses statistics to make a point that apparently isn’t true:

What I want to delve into is the claim by the author that wildfires are increasing due to global warming, and only evil Republicans (who suck) could possibly deny this obvious trend […]

These are the 8 statements I can find to support an upward trend in fires. And you will note, I hope, that none of them include the most obvious data — what has the actual trend been in number of US wildfires and acres burned. Each of these is either a statement of opinion or a data point related to fire severity in a particular year, but none actually address the point at hand: are we getting more and larger fires?

Maybe the data does not exist. But in fact it does, and I will say there is absolutely no way, no way, the author has not seen the data. The reason it is not in this article is because it does not fit the “reporters” point of view so it is left out. Here is where the US government tracks fires by year, at the National Interagency Fire Center. To save you clicking through, here is the data as of this moment:

Wildfire averages 2004-2013

Well what do you know? The number of fires and the acres burned in 2013 are not some sort of record high — in fact they actually are the, respectively, lowest and second lowest numbers of the last 10 years. In fact, both the number of fires and the total acres burned are running a third below average.

The one thing this does not address is the size of fires. The author implies that there are more fires burning more acres, which we see is clearly wrong, but perhaps the fires are getting larger? Well, 2012 was indeed an outlier year in that fires were larger than average, but 2013 has returned to the trend which has actually been flat to down, again exactly opposite of the author’s contention (data below is just math from chart above)

Wildfires average acres per fire 2004-2013

In the rest of the post, I will briefly walk through his 8 statements highlighted above and show why they exhibit many of the classic fallacies in trying to assert a trend where none exists. In the postscript, I will address one other inconsistency from the article as to the cause of these fires which is a pretty hilarious of how to turn any data to supporting your hypothesis, even if it is unrelated.

The IPCC’s new, more cautious tone

Filed under: Environment, Media, Science — Tags: , , , , — Nicholas @ 07:41

In The Spectator, a muted tone of “we told you so” about the upcoming IPCC report:

Next week, those who made dire predictions of ruinous climate change face their own inconvenient truth. The summary of the fifth assessment report by the Intergovernmental Panel on Climate Change (IPCC) will be published, showing that global temperatures are refusing to follow the path which was predicted for them by almost all climatic models. Since its first report in 1990, the IPCC has been predicting that global temperatures would be rising at an average of 0.2° Celsius per decade. Now, the IPCC acknowledges that there has been no statistically significant rise at all over the past 16 years.

It is difficult to over-emphasise the significance of this report. The IPCC is not simply a research body making reports and declarations which are merely absorbed into political debate. Its word has been taken as gospel, and its research has been used to justify all manner of schemes to make carbon-based energy more expensive while subsidising renewable energy.

The failure of its predictions undermines the certainties which have been placed upon the science of climate change. Previous IPCC reports — and much of the debate over how to react to them — have appeared to treat the Earth’s climate as if it were a domestic central heating system, with carbon emissions analogous to the dial on the thermostat: a small tweak here will result in a temperature rise of precisely 0.2°C and so on. What is clear from the new IPCC report is that the science is not nearly advanced enough to make useful predictions on the future rise of global temperatures. Perhaps it never will be.

Some climate scientists themselves, to give them credit, have admitted as much. Their papers now incorporate a degree of caution, as you would expect from genuine scientists. The problems arise when the non-scientists leap upon the climate change bandwagon and assume that anything marked ‘science’ must be the final word. As the chemist and novelist C.P. Snow once warned in his lecture about the ‘two cultures’, you end up in a situation where non-scientists use half-understood reports to silence debate — not realising that proper science welcomes refutation and is wary of the notion of absolute truths.

The Economist on the cooling chances of major climate control legislation

Filed under: Environment, Government, Media, Science — Tags: , , — Nicholas @ 09:37

I was disappointed when The Economist switched sides to join the “consensus” on global warming and started arguing for massive government intervention in the economy to “save the planet”. Fifteen years after the last significant bout of warming, The Economist is starting to sound a bit more sensible (and skeptical):

…there’s no way around the fact that this reprieve for the planet is bad news for proponents of policies, such as carbon taxes and emissions treaties, meant to slow warming by moderating the release of greenhouse gases. The reality is that the already meagre prospects of these policies, in America at least, will be devastated if temperatures do fall outside the lower bound of the projections that environmentalists have used to create a panicked sense of emergency. Whether or not dramatic climate-policy interventions remain advisable, they will become harder, if not impossible, to sell to the public, which will feel, not unreasonably, that the scientific and media establishment has cried wolf.

Dramatic warming may exact a terrible price in terms of human welfare, especially in poorer countries. But cutting emissions enough to put a real dent in warming may also put a real dent in economic growth. This could also exact a terrible humanitarian price, especially in poorer countries. Given the so-far unfathomed complexity of global climate and the tenuousness of our grasp on the full set of relevant physical mechanisms, I have favoured waiting a decade or two in order to test and improve the empirical reliability of our climate models, while also allowing the economies of the less-developed parts of the world to grow unhindered, improving their position to adapt to whatever heavy weather may come their way. I have been told repeatedly that “we cannot afford to wait”. More distressingly, my brand of sceptical empiricism has been often met with a bludgeoning dogmatism about the authority of scientific consensus.

Of course, if the consensus climate models turn out to be falsified just a few years later, average temperature having remained at levels not even admitted to be have been physically possible, the authority of consensus will have been exposed as rather weak. The authority of expert consensus obviously strengthens as the quality of expertise improves, which is why it’s quite sensible, as matter of science-based policy-making, to wait for a callow science to improve before taking grand measures on the basis of it’s predictions.

As I wrote back in 2004, “I’ve never been all that convinced of the accuracy of the scientific evidence presented in favour of the Global Warming theory, especially as it seemed to play rather too clearly into the hands of the anti-growth, anti-capitalist, pro-world government folks. A world-wide ecological disaster, clearly caused by human action, would allow a lot of authoritarian changes which would radically reduce individual freedom and increase the degree of social control exercised by governments over the actions and movement of their citizenry.”
