“This thought-provoking talk is based on Dr. Lomborg’s bestselling book and film, Cool It. Here, Lomborg will demonstrate how we’re often told very one-sided and exaggerated claims about the environment and climate change, leading to unwarranted panic, instead of rationally assessing where and how we can do the most good. He argues that to tackle global warming we need smarter solutions focused on getting long-term solutions like cost-competitive renewables and that many of the impacts of global warming would be better addressed through adaptation.”

Lomborg is best known as the author of The Skeptical Environmentalist and Cool It, two books that downplay the risks of global warming. Lomborg does not have a background in climate science and has published no peer-reviewed articles in journals devoted to climate change research. He has, however, authored policy studies arguing against climate change prevention measures. He wrote a similar article in the peer-reviewed journal Technological Forecasting and Social Change where he claimed, “Climate policies also have costs that often vastly outweigh their climate benefits.”

Lomborg’s Errors

Lomborg’s errors in his discussion of climate change have been documented by many sources including a 2010 book published by Yale University Press titled The Lomborg Deception: Setting the Record Straight About Global Warming. is a website focused on documenting his errors, although it does not appear to have been recently updated.

Stance on Climate Change

In a 2010 report in The Guardian, Lomborg acknowledged that global warming is “a challenge that humanity must confront.” Lomborg goes as far as calling for a carbon tax and a $100 billion investment in clean technologies.10Juliette Jowit. “Bjørn Lomborg: $100bn a year needed to fight climate change,” The Guardian, August 30, 2010. Archive .is URL:

However, in his new book Smart Solutions to Climate Change, Lomborg argues that it would be too expensive to implement any major carbon reduction policy, and that “drastic carbon cuts would be the poorest way to respond to global warming.”11Howard Friel. “Bjørn Lomborg’s missing questions,” The Guardian, August 30, 2010. Archive .is URL:

As Desmog reports, Lomborg appears to be directly contradicting himself.12James Hoggan. “Bjorn Lomborg’s Climate Confusionist Spin Is Never Ending,” Desmog, September 17, 2010.

On December 6, 2013 (three days after Lomborg wrote an op-ed for The New York Times Opinion page), The Guardian released an article entitled, “Is Bjorn Lomborg right to say fossil fuels are what poor countries need?13Graham Readfearn. ”Is Bjorn Lomborg right to say fossil fuels are what poor countries need?“ The Guardian, December 6, 2013. Archive .is URL: where Lomborg’s latest solution to climate change is again to give the globe more access to cheap fossil fuels. This has developed into a term which was coined “energy poverty.”14Bjorn Lomborg. ”The Poor Need Cheap Fossil Fuels,” The New York Times The Opinion Pages, December 3, 2013. Archive .is URL:

Green Energy

Lomborg has described solar panels as inefficient and states this is “why you have to subsidize them.”15RN DRIVE 02.12.2013,, December 2, 2013.

In what appears contradictory, Lomborg then advocates for investments in green energy technologies, “…At the same time, wealthy Western nations must step up investments into research and development in green energy technologies to ensure that cleaner energy eventually becomes so cheap that everyone will want it.”16Graham Readfearn. ”Is Bjorn Lomborg right to say fossil fuels are what poor countries need?“ The Guardian, December 6, 2013. Archive .is URL: 17Bjorn Lomborg. ”The Poor Need Cheap Fossil Fuels,” The New York Times The Opinion Pages, December 3, 2013. Archive .is URL:


Lomborg has promoted the controversial idea of geo-engineering to address climate change.18Mitchell Anderson. “Lomborg’s Robot Navy,” DeSmog, August 10, 2009. In one instance, Lomborg envisioned a fleet of 1900 robotic ships that will patrol the ocean while releasing spouts of ocean water to reflect the sun’s rays in an attempt to reduce global warming.19Lomborg says armada could halt global warming,” The Copenhagen Post Online, August 7, 2009.

“As surely as temperatures rise during the summer, climate alarmism serves up more stories of life-threatening heat domes, apocalyptic fires and biblical floods, all blamed squarely on global warming. Yet, the data to prove this link is often cherry-picked, and the proposed policy responses could be more effective,” Lomborg wrote. He concluded: “To do better on climate, we must resist the misleading, alarmist climate narrative.”

A Guardian report detailed how, in the face of unprecedented wildfires across much of the world, Lomborg argued that wildfires were becoming less commonplace and less severe globally.26Graham Readfearn. “The world likely just had its hottest month on record. What a time to be a climate science denier,” The Guardian, August 3, 2023. Archived August 1, 2023. Archive URL:

In a tweet he said:

“Climate alarmists scare us with ever more fire. But satellites show the world is burning ever less.

Lomborg tweeted a link to his article, published in the journal Technological Forecasting and Social Change, which claims to show agreement across various modelled scenarios global will be only moderately impacted by 8 degrees of global warming. 
In the paper, Lomborg makes the case that the costs of taking climate action “vastly outweigh” the costs imposed by climate change itself. He argued that the 2 degree target is economically “unrealistic” and that a favourable scenario would see a reduction of warming from 4 degrees to 3.75 degrees.

He argued that:

“The current climate discourse leads to wasteful climate policies, diverting attention and funds from more effective ways to improve the world.”’

July 31, 2023

Lomborg wrote an opinion piece for the Wall Street Journal entitled “Climate Change Hasn’t Set the World on Fire,” where he argued the area of land burned each year has been in decline since 2001, despite “one of the most common tropes in our increasingly alarmist climate debate” that wildfires are becoming more prevalent with climate change.28Bjorn Lomborg. “Climate change hasn’t set the world on fire,” Wall Street Journal, July 31, 2023. Archived August 1, 2023. Archive URL: He accused the media of “cherry-picking” when reporting on wildfires, in particular over claims about the number of animal deaths resulting from wildfires. 

He added that claims that climate policy is the only way to reduce wildfires were “embarrassingly wrong” 

Lomborg asserted that wildfire reporting was one of many climate “scare-duds,” citing media discourse of threats to polar bears from climate change as a prime example given an apparent increase in the polar bear numbers in the past half-century. 

In relation to climate policy, he argued that:

“The common-sense response would be to recognize that both climate change and carbon-cutting policies incur costs, then negotiate a balance that puts the most effective measures first.” 

July 2, 2023

In an interview with the New York Post, Lomborg characterised climate debate as “scaremongering” over the threat of climate change and “we just need to have a sense of proportion” in relation to other issues.29John Stossel. “Spend climate-change cash on better causes to save millions of lives,” New York Post, July 2, 2023.

In an article for the National Review, Lomborg uses a series of eight graphs, six of which are his own, to argue that the threat of climate change is consistently overstated, that “global warming is real, but it is not the end of the world.” He characterised “the global discussion about climate change” as “hysterical,” arguing that this was “drowning out many other relevant facts about climate change.” He uses the piece to argue that the most effective way to combat climate change would be to invest in research and development of new clean technologies, rather than cutting back on fossil fuel production in the short-term.35Bjørn Lomborg. “Life after climate change,” National Review, March 30, 2023. Archived March 30, 2023. Archive URL:

One of the eight graphs included in the piece is on “the cost of going net zero” which Lomborg characterised as “fantastically expensive” meaning that “these policies are doomed to failure.” 

Elsewhere, Lomborg uses another graph to argue that climate change was not making hurricanes more likely, adding that “these days, every weather phenomenon is turned into instant climate news.”

Another graph takes on the issue of heat and cold related deaths, where Lomborg argues that while climate change will increase the number of heat deaths each year, this will be more than offset by a reduction in deaths from cold. He argued that reducing deaths from extreme temperatures would require “access to plentiful and cheap energy — the opposite of what many climate policies would achieve.

Lomborg references another graph to argue that Polar bear populations have recovered significantly since the 1960s due a reduction in hunting, arguing that climate change should be discounted in polar bear population numbers as “if we care about polar bears, it is hunting that we should focus on.”

A graph on malnutrition is used by Lomborg to argue against WHO predictions that the number globally suffering from malnutrition will increase due to climate change. He instead makes the case that economic development alone will mean more people will have access to a nutritious diet, offsetting a loss in crop yields due a warming climate. 

On the subject of climate-related deaths, Lomborg argues that climate-related deaths would decrease due to technological advancement and that “not only is climate not the big killer of our times, it also isn’t claiming more lives than before.” 

A final graph, created by Lomborg, shows the trajectory of the global share of renewables, which he uses to argue that renewables will not, and cannot replace fossil fuels on the 2050 net zero timeline, making the prospect of meeting these targets “hardly realistic.” 

In conclusion, Lomborg makes the case against cutting fossil fuel production, adding: 

“Climate change will be solved not by making fossil energy unaffordable, but by innovating the price of green technologies downward so that everyone can afford the switch.”

In a tweet, he labelled the thesis that climate change could worsen the spread of malaria “climate doomism,” also posting a graph which claims to show that climate change would only marginally worsen the spread of malaria versus a non-climate change scenario.36Bjorn Lomborg. “Climate doomism: Higher temps: more people 𝗰𝗼𝘂𝗹𝗱 get malaria In real life, you get malaria if you’re poor Malaria endemic in 36 US states before 1940s bc poverty Malaria decreases bc development climate just slows improvement slightly,” Tweet by user @BjornLomborg, April 15, 2023.

Archived May 16, 2022. Archive URL:

He added:

“They might ask whether the obsession with climate change in recent decades has taken attention away from the many other major problems facing the planet. And they might also look at ‘extreme weather events’ and whether they really are claiming more lives.”

Lomborg also argued that though the “commercial cost of hurricane damage” will increase due to climate change, but “because the world will also get richer, relative damages will keep declining, just slightly more slowly than they would have done”.

Similarly, he argued that deaths from the cold were a greater risk than excess deaths from rising temperatures, writing “it’s all about perspective” and that: 

“By the UN’s own estimates, the average person in 2100 will be 450 per cent richer than today. Global warming will make this increase 4 per cent smaller, reducing it by 16 percentage points. It means that the average person in 2100 will ‘only’ be 434 per cent as rich. This is not a disaster.”

He added: “There certainly are studies showing that low-lying Bangladesh will be threatened by sea level rises by the end of the century. But similarly, the UN also assumes that by then Bangladesh will be richer than the Netherlands is now, and able to afford flood defences.”

In an article for The Herald titled “Bjorn Lomborg: Fracking could be the answer as Europe seeks energy independence”, Lomborg argued that “we have been sold a largely untrue story that renewables can give us energy independence” because “the key renewables […] only work when the sun is shining or the wind is blowing”.42Bjorn Lomborg. “Bjorn Lomborg: Fracking could be the answer as Europe seeks energy independence”, The Herald, April 14, 2022.

He also claimed that “all the batteries in Europe can store power for just one minute and 21 seconds of the continent’s average electricity demand”, adding: “after that we’re back to relying mostly on fossil fuel backup”.

According to Lomborg, Europe should “reconsider producing its own natural gas through fracking, like the US did” because “Fracking could deliver cheap energy, complete energy independence, and has reduced US emissions dramatically”.

Addressing the concerns which led to the UK’s fracking ban, he wrote that “most can be addressed with good regulation”, repeating the claim that “most of Europe has rejected fracking because of exaggerated fears, spread with financial help from Russia”.

He concluded by suggesting that fracking is the “most pragmatic option” to increase energy security “for the short run”, and that gas “ could generate plentiful, cheap gas and huge economic benefits, while reducing emissions”.

Lomborg stated that the “elite” have “worked hard” to make fossil fuels “both more expensive and less available for the world’s poorest” while Western countries remain “overwhelmingly powered by fossil fuels”.

He also criticised the media, writing: 

“For years the media has portrayed the effects of climate change as horrendous. Today almost every natural disaster routinely gets blamed on the climate crisis, with every new hurricane or destructive flood held up as another exhibit of human folly. Yet hurricanes killed many more people in the past.”

Lomborg continued to argue that we shouldn’t worry about global climate damage, writing: “Global climate damage as a percentage of GDP keeps declining […] Remember, by the UN’s own estimates the average person in 2100 will be 450% richer than today. Global warming means that person will ‘only’ be 434% as rich.”

He concluded: 

“Climate should be tackled more effectively by funding research into green energy sources so they eventually outcompete fossil fuels […] We need our perspective back to overcome the elitist hyperbole on climate change.”

“The new report has no comparison of the costs and benefits of climate targets. Mr. Nordhaus’s most recent estimate, published in August, is that the ‘optimal’ outcome with a moderate carbon tax is a rise of about 6.3 degrees Fahrenheit by the end of the century.

Archived .pdf on file at Desmog. Archive .is URL: Archive .is URL:

“Climate change is a genuine problem that will eventually be a net detriment to society. Gradually rising temperatures across decades will increase the number of hot days and heat waves. If humans make no attempts whatsoever to adapt—a curious assumption that the report inexplicably relies on almost throughout—the total number of heat-related deaths will rise. But correspondingly, climate change will also reduce the number of cold days and cold spells. That will cut the total number of cold-related deaths.”

“In pushing too hard for the case that global warming is universally bad for everything, the administration’s report undermines the reasonable case for climate action. Focusing on only the bad side of the ledger destroys academic and political credibility.”

Lomborg was quoted in a piece titled, “Climate change real, deadly says David Attenborough,” in which Lomborg says that “the UN should focus on more cost-effective environmental policies,” and increase their global target for limiting warming from 2C to 3C:50Climate change real, deadly says David Attenborough,” The Australian (sub. required), January 2, 2015.

“Pursuing this 2C target is very costly and not guaranteed to be successful. Much better, then, to target a maximum of, say, 3C rise, which will cost about $40 trillion but avoid most damages.

“If we insist on 2C, we will pay an extra $60,000 billion, but only prevent a stream of $100 billion damages that begins in 70 to 80 years. Moreover, all of these estimates assume cost-effective climate policies, whereas in real life they have often become many times more expensive.”

In an opinion piece written by Lomborg in The Australian entitled, “Renewables pave path to poverty,” Lomborg encourages everyone engaged in the debate [of Australia’s Renewable Energy Target (RET)] to “recognise:”51Bjorn Lomborg. ”Renewables pave path to poverty,” The Australian, April 29, 2014.

“The Australian government recently released an issues paper for the review of the renewable energy target. What everyone engaged in this debate should recognise is that policies such as the carbon tax and the RET have contributed to household electricity costs rising 110 per cent in the past five years, hitting the poor the hardest.”

Further on, he states:

“In 1971, 40 per cent of China’s energy came from renewables. Since then it has lifted 680 million people out of poverty using coal. Today, China gets a trifling 0.23 per cent of its energy from wind and solar. Africa gets 50 per cent of its energy today from ­renewables — and remains poor. New analysis from the Centre for Global Development shows that, investing in renewables, we can pull one person out of poverty for about $US500. But, using gas electrification, we could quadruple that. By ­focusing on our climate concerns, we deliberately choose to leave more than three out of four people in darkness and poverty. Addressing global warming requires long-term innovation that makes green energy affordable. Until then, wasting enormous sums of money at the expense of the world’s poor is no solution at all.”

“A new paper by Todd Moss and Ben Leo from the nonprofit think tank, Center for Global Development, puts it very clearly. If Obama spends the next $10 billion on gas electrification, he can help lift 90 million people out of poverty. If he only uses renewables, the same $10 billion can help just 20 million-27 million people. Using renewables, we will deliberately choose to leave more than 60 million people in darkness and poverty…Our development aid should be used to help 60 million more people out of poverty, not as a tool to make us feel virtuous about facile, green choices.”52Lomborg: Obama energy policy hurts African poor,” USA Today,February 8, 2014.

In an op-ed in The New York Times, Lomborg writes:

“There’s no question that burning fossil fuels is leading to a warmer climate and that addressing this problem is important. But doing so is a question of timing and priority. For many parts of the world, fossil fuels are still vital and will be for the next few decades, because they are the only means to lift people out of the smoke and darkness of energy poverty.”53Bjorn Lomborg. ”The Poor Need Cheap Fossil Fuels,” The New York Times The Opinion Pages, December 3, 2013. Archive .is URL:

Lomborg hosts a TED Blog video titled, “What do global problems cost us?” as a follow up to his previous TED Talk in 2005:

9:30-10:20 “If you look at the time period from 1900 to 2050, surprisingly, for a lot of people, the net impact of most global warming was actually positive. That’s because CO2 is actually fertilizer, that means it increases our agricultural production. Of course, in the long run increasing temperatures is also going to reduce agricultural production. We will also see more people die from heat, but many more people will avoid to die from cold, again with moderate global warming. We are also seeing the lower costs of heating outweigh the extra costs of cooling. So, actually, if you look at what the cost is [of global warming] it turns out to be a slight negative around 1900 at about 0.5% and across the most of the century, mostly a negative.”54Bjorn Lomborg. “What do global problems cost us?TED Blog Videos, November 12, 2013.

“We have to ask ourselves: what do we want to do first? Do we want to focus on cutting CO2, at fairly high costs and doing fairly little good a hundred years from now? Or would we rather want to fix some of the many obvious problems in the world, where we could do a lot more good and do it now?”55“Perspective on Climate Change” (PDF), Testimony prepared by Bjorn Lomborg for the Subcommittee on Energy and Air Quality joint hearing with the Subcommittee on Energy and Environment of the Committee on Science and Technology on Wednesday March 21, 2007.

He also argued that instead of following “a net-zero approach that brings so much pain for so little climate reward”, the “best long term strategy is to dramatically increase investment in green-energy research and development”.

Lomborg then criticised solar and wind energy, writing that they “can only work with massive amounts of backup power, mostly fossil fuels”.

In a Boston Herald article titled “Lomborg: Want to alleviate world hunger? Ditch the organics”, Lomborg criticised “the rich world’s obsession with organics”, saying “organic farming cannot feed the world and could even worsen future crises”.66Bjorn Lomborg. “Lomborg: Want to alleviate world hunger? Ditch the organics”, Boston Herald, May 31, 2022. Archived May 31, 2022. Archive URL:

He argued that organic farming was a “fashionable trend for the world’s 1%” and that “research conclusively shows that organic farming produces much less food than conventional farming per acre”.

After suggesting that Russia’s invasion of Ukraine “has reaffirmed the basic reality that fossil fuels remain crucial for the vast majority of global needs”, Lomborg celebrated synthetic nitrogen fertilisers, “mostly made with natural gas”, as “a modern miracle, crucial for feeding the world”.

May 6, 2022

In a Wall Street Journal article titled “Ukraine crisis reveals the folly of organic farming”, Lomborg argued that organic farming is “ineffective”, writing:

Lomborg also criticised the widely-contested practice of burning wood as a form of renewable energy, writing: 

“At the moment, 60 per cent of the EU’s total renewable energy comes from burning wood pellets. But while wood energy is in principle renewable, cutting down more and more forest can have huge biodiversity impacts. Moreover, wood emits more CO₂ than coal when burned, and it is often imported and transported on diesel ships from the U.S.”

In an interview with CityAM titled “Exclusive: ‘Nuclear has a lot going for it while net zero will simply not happen’”, says sceptical environmentalist Bjorn Lomborg”, Lomborg said:

“There are definitely costs from climate change, which is why global warming is a net problem. But regardless of any realistic climate policies, the costs will remain almost the same for the next many decades because of inertia in the climate system. Remember, even if the entire rich world went net-zero today, it would reduce global warming in 2050 with less than 0.2°C, using the UN’s own climate model.”69Bjorn Lomborg. “Exclusive: ‘Nuclear has a lot going for it while net zero will simply not happen’, says sceptical environmentalist Bjorn Lomborg”, City AM, February 22, 2022.

He added that “going 100% renewable does not make you energy secure”, and that “bioenergy is mostly just a fancy way of saying burning wood, which provides 60 per cent of all renewable energy and is especially problematic in poor countries where it leads to excessive indoor air pollution and deforestation.”

Lomborg also argued that tackling climate change “would require governments to stop spending about half on schools, hospitals and all other items on the social menu, or increase taxes by 50%, either of which are simply political non-starters”.

He also called Environmental, Social and Governance (ESG) – a social responsibility metric for companies, referred to by the interviewer as “a buzzword in the City of London”, a “hollow tool”, saying: 

“ESG is alluring because it suggests that you can get rich while doing good for the world. As usual, when something seems too good to be true, it is. Investing for doing good will sometimes generate higher returns, though clean tech is crashing right now, but if this was true in general, everyone would be doing good and you wouldn’t need ESG.”

Lomborg wrote an article at The Australian following the UN Climate Conference in Glasgow (COP26) claiming, “It is easy and popular for politicians to talk up the dangers of climate change and promise safety with grandiose policies for 2030 or 2050.

Reporting from The Guardian found that a key claim Lomborg made in the column, which also appeared in The Herald in Scotland and the Economic Times in India, had appeared in a Nature Climate Change study whose authors had been asking Lomborg to stop making the claim since early November.72Graham Readfearn. “Climate cost study authors accuse Bjørn Lomborg of misinterpreting results,” The Guardian, December 2, 2021. Archived December 17, 2021. Archive URL:

“Lomborg wrote in the Australian that a study’“in the renowned journal’ Nature, ‘shows that reducing emissions 95% by 2050 – almost Biden’s promise of net zero – would cost 11.9% of gross domestic product, or more than $US11,000 ($15,300) for each American citizen every year’,” Graham Readfearn reported.

“That seems like an eye-watering figure, or in Lomborg’s words ‘spectacularly costly’.

“The cited figure does appear in a supplementary section of the paper. But the authors of the study (which actually appeared in Nature Climate Change, not Nature) have told Temperature Check they have been asking Lomborg since early November to stop making that claim.

“Prof David Victor, of University of California San Diego, said Lomborg’s summary ‘took the results out of context and used them for a purpose that we explicitly said they were not to be used, and which he was reminded of when he asked for the underlying data’.

“Dr Wei Peng, of Penn State university and lead author of the study, said she and her colleagues were ‘frustrated with Lomborg’s misinterpretation of our study’.

“In late October Peng emailed Lomborg saying the modelling results for emissions cuts at 95% “was not well calibrated, and the cost number is likely to be off”.

“I hope people won’t take the high mitigation cost out of context,” she told Lomborg.

“Victor said Lomborg’s use of the figure was ‘obscenely reckless’ in the context of ‘serious scientific analysis’ and wrote to him in early November.”

Archived October 17, 2022. Archive URL:

Lomborg added that since the adoption of the Kyoto Protocol, the first major global agreement to cut carbon emissions, “the world has hosted hundreds of climate summits and rich nations have reliably talked green; but emissions have kept increasing”, which Lomborg writes is because “no leaders want to stick their citizens with the huge price tag”.

He argued: 

“What is needed is a much stronger focus on green energy research. If the world could innovate green energy that was cheaper than fossil fuels, we would have solved global warming. Everyone would switch — not just rich well-meaning countries like the U.S., but everyone, including China and India.”

“Fundamentally, we’ve got to stop the alarmists,” Lomborg told Thiessen, claiming that while a recent poll found young Americans “humanity is doomed” actually things are a lot better than you think.”

Thiessen concluded, based on Lomborg’s suggestions, “The way to address climate change is to unleash the free market to increase prosperity and innovation. But climate alarmists are using false claims of doom to scare people into adopting policies that will have the opposite effect — destroying economic growth and increasing global poverty.”

“Even if all electricity turned green, most of the world would still run on fossil fuels,” Lomborg wrote. “Though renewables are often touted as the cheapest energy source, it’s only true when the sun is shining and the wind is blowing. If it’s a still night you need backup power, typically from fossil fuels—which makes electricity costlier because you need to pay for both the solar panel and the gas turbine.”

He concluded:”In 2021 emissions would have to drop by more than double the [Covid-]lockdown-induced decline. By the end of 2030, they’d have to have fallen by 11 times what they did in 2020. Not exactly realistic.”

In an article for Euractiv, Lomborg criticised the EU’s decarbonisation plans, describing them as “a costly way of achieving almost nothing”. Lomborg argued that “this does not mean that the EU should do nothing. It should do something smarter. The fundamental problem with climate policy is that switching to zero-carbon now is expensive. That means rich, well-meaning Europeans can afford a bit, but globally little will happen”. Lomborg also stated that, “climate change is a real and man-made problem that should be tackled sensibly.

Lomborg appeared in a podcast for The Spectator alongside self-described climate “lukewarmer” Matt Ridley and Kate Andrews of the Institute of Economic Affairs (IEA), discussing whether tackling climate change ought to be considered a top priority.95Kate Andrews, Matt Ridley, Bjorn Lomborg. “A question of priorities: should tackling climate change trump all else?,” The Spectator, September 8, 2020.

Lomborg disputed that counteracting climate change was a priority for the world’s poorest nations, stating: “If you actually want to help the world’s poor, they have many other much, much more important issues they want us to fix first, and fortunately, we can also fix them much cheaper and much more effectively.” He also stated that the Paris Agreement would achieve “almost nothing in 100 years,” and that “we probably won’t be able to measure the difference even if we continue to stick to the Paris agreements throughout the 21st century.”

Lomborg featured alongside Matt Ridley in a six-part podcast series about climate change presented by economics correspondent for the Spectator and former Associate Director of the Institute of Economic Affairs, Kate Andrews.

In the first episode of the series, Lomborg claimed that climate change was “a problem” but “not the end of the world” and criticised statements from the U.N Secretary General, Antonio Guterres and Democratic presidential candidate, Joe Biden, suggesting that climate change posed an existential threat to humanity. Lomborg said that to present climate change in this way was “alarmism” and “wrong.”96Don’t Panic! How to talk about climate change – episode 1,” The Spectator, August 25, 2020.

Lomborg published an article in Technological Forecasting and Social Change titled “Welfare in the 21st century: Increasing development, reducing inequality, the impact of climate change, and the cost of climate policies.”97Bjorn Lomborg. “Welfare in the 21st century: Increasing development, reducing inequality, the impact of climate change, and the cost of climate policies,” Technological Forecasting and Social Change, Volume 156 (July 2020) 119981, ISSN 0040-1625. Archived November 5, 2020. Archive URL:

He wrote in conclusion:

“As municipalities, counties, and even countries declare a “climate emergency,” it is apparent that global warming is often being presented as an existential challenge requiring urgent and strong climate policies to avoid devastation.

“This article has shown that these claims are misleading and often incorrectly describe the issue and its future. While climate change is real, human caused, and will have a mostly negative impact, it is important to remember that climate policies will likewise have a mostly negative impact. Thus, we must account for the effects of both to find the policies that will achieve the highest welfare gains.”

“By focusing solely on GDP as the only measure of humanity’s wellbeing, Lomborg disregards the reality of what 3.75C of warming would mean.

Lomborg published a book titled False Alarm: How Climate Change Panic Costs Us Trillions, Hurts the Poor, and Fails to Fix the Planet. It was promoted by the Institute for Energy Research and the Hoover Institution among other groups.99Joseph E. Stiglitz. “Are We Overreacting on Climate Change?The New York Times, July 16, 2020. Archived July 31, 2020. Archive URL:

The thesis of the book, reported in a review at the New York Times, was that “Activists have been sounding a false alarm about the dangers of climate change. If we listen to them, Lomborg says, we will waste trillions of dollars, achieve little and the poor will suffer the most.”100Joseph E. Stiglitz. “Are We Overreacting on Climate Change?The New York Times, July 16, 2020. Archived July 31, 2020. Archive URL:

Joseph E. Stiglitz of The New York Times notes that, “Somehow, missing in his list of good policy measures are easy things like good regulations — preventing coal-burning electric generators, for example.” Stiglitz adds that Lomborg, “exhibits a naïve belief that markets work well — ignoring a half-century of research into market failures that says otherwise — so well, in fact, that there is no reason for government to intervene other than by setting the right price of carbon.”

“A second mistake — which biases the results in the same way — is Nordhaus’s and Lomborg’s underestimation of the damage associated with climate change.” Examples of that damage include ocean acidification and sea level rise. “Climate change also includes more extreme weather events — more intense hurricanes, more droughts, more floods, with all the devastation to life, livelihood and property that accompanies them.”

A third mistake identified in the article is “not taking due account of risk.”

“As the atmospheric concentration of carbon increases, we are entering uncharted territory. Not since the dawn of humanity has there been anything like this. The models use the ‘best estimate’ of impacts, but as we learn more about climate change these best estimates keep getting revised, and, typically, in only one direction — more damage and sooner than had been expected.”

Stiglitz concluded:

“This book proves the aphorism that a little knowledge is dangerous. It’s nominally about air pollution. It’s really about mind pollution.”

IER disagreed with Lomborg’s case of a tax on carbon, suggesting “a no-carbon-tax policy is better than the ‘optimal’ carbon tax.”101David Kreutzer. “Book Review: False Alarm by Bjørn Lomborg,” Institute for Energy Research, July 7, 2020. Archived July 31, 2020. Archive URL:

Lomborg posted a graph on his Facebook page claiming that “Over the past hundred years, annual climate-related deaths have declined by 96%”.

While he admitted climate change was real, Lomborg also claimed it was an exaggerated threat that does not pose an existential crisis for humanity, and dismissed concerns (found in a recent YouGov poll) about humanity’s potential for extinction as “just silly.”

He equated the impacts of climate change, given increased wealth in the world, as not much worse than a recession:

It’s the equivalent to about one recession over the next 50 years,” he said. “That’s a problem, but it’s certainly not the end of the world.”

If you want to help people,” he said, “you have to ask yourself do we want to help future generations by cutting carbon emissions and hence having them experience less climate change or do we want them to be more resilient against climate change by making sure they get out of poverty and get richer?”

In response, van Baal, said:

I think the only way to do so is to make sure the oil and gas industry changes its course, stops investing in exploring for even more oil and gas and start exploring new business models. It’s simple as that.”

The Australian reported Lomborg was among those named in a statement by academic website The Conversation, which said it would ban comments from climate change deniers.105Graham Lloyd. “No place in debate for climate contrarians,” The Australian, September 21, 2019.

Discrepancy in scientific authority and media visibility of climate change scientists and contrarians. Nat Commun 10, 3502 (2019).

Alex Petersen, lead author of the study, said: “It’s time to stop giving these people (contrarians) visibility, which can be easily spun into false authority. … By tracking the digital traces of specific individuals in vast troves of publicly available media data, we developed methods to hold people and media outlets accountable for their roles in the climate change denialism movement, which has given rise to climate change misinformation at scale.”

Curry said the paper “does substantial harm to climate science … There are a spectrum of perspectives, especially at the knowledge frontiers. Trying to silence or delegitimise any of these voices is very bad for science.”

The Conversation‘s editor and executive director Misha Ketchell commented: “We moderate anything that is a deliberate misinformation and distortion of facts or attempts to misrepresent arguments or community members. We know climate sceptics are very good at derailing constructive conversations, so we’ll remove comments that attempt to hijack threads or to push an agenda or argument irrelevant to the discussion.”

Lomborg issued a critical assessment of the COP-24 climate summit by claiming that the IPCC’s stated goal of limiting global temperature increase to less than 1.5 degrees Celsius is “infeasible and unrealistic.” He also stated that abiding by the Paris agreement to meet this goal would negatively affect global GDP growth to the tune of up to $2 trillion annually after 2030 while having a negligible impact on temperature reduction.111Bjorn Lomborg. “Another climate summit means more expensive, ineffective promises,”, December 6, 2018. Archived December 12, 2018. URL:

Lomborg also criticized news reporting of the U.S. Climate Assessment, released by the Trump administration the day after Thanksgiving, as portraying a bleaker picture than the report actually revealed. The true cost to the global economy, from Lomborg’s perspective, would come not from extreme weather events and increased mortality rates, but from the imposition of “immature energy sources” to replace fossil fuels.

Minimizing the effect that rising global temperatures will have on mortality rates, Lomborg said:

It is true more people die when it is unusually hot, but lives are not shorter in hotter places. (Otherwise, everyone would move from Texas to Alaska). Studies of migrants show people adapt quickly, within weeks. They also take actions like getting an air conditioner or adapting their houses that reduce their risk of overheating.”

Lomborg, writing at The Wall Street Journal, criticized the recent United Nations report on climate change:112Bjorn Lomborg. “U.N. Ignores Economics Of Climate,” Wall Street Journal, October 9, 2018. URL:

Limiting temperatures to 2.7 degrees Fahrenheit above preindustrial levels, as the U.N.’s Intergovernmental Panel on Climate Change urges, is economically and practically impossible,” Lomborg claimed, citing economist William Nordhaus as evidence.

Lomborg is one of several individuals and groups—including the industry-backed Institute for Energy Research (IER)—that selectively cited Nordhaus’s work as evidence that the IPCC’s targets are unrealistic.113Robert P. Murphy. “The IPCC Should Heed the Work of Nobel Laureate William Nordhaus,” Institute for Energy Research, October 9, 2018. Archived October 23, 2018. URL:

The IER article, giving a hat tip to David Henderson, pointed to research done by Nordhaus in 2007. However, in a more recent discussion paper from 2016, using an updated 2016 DICE model, Nordhaus “confirms past estimates of likely rapid climate change over the next century if there are not major climate-change policies.”114“PROJECTIONS AND UNCERTAINTIES ABOUT CLIMATE CHANGE IN AN ERA OF MINIMAL CLIMATE POLICIES” (PDF), Cowles Foundation, December 2016. Archived .pdf on file at DeSmog.

In his 2016 paper’s introduction, Nordhaus wrote:

[W]e must take stock of what we know now as well as the implications of our actions. And the bottom line here is that this most recent taking stock has more bad news than good news, and that the need for policies to slow climate change are more and not less pressing.”

The August 2018 revision of Nordhaus’s paper that Lomborg appears to be citing includes the identical paragraph as above. In his paper, Nordhaus also notes that uncertainties surrounding the damages of climate change make it more important to act sooner and with stronger policies:115“Projections and Uncertainties about Climate Change in an Era of Minimal Climate Policies” (PDF), American Economic Journal Vol. 10 No. 3 (August 2018).

The ranges of uncertainty for future emissions, concentrations, temperature, and damages are extremely large. However, this does not reduce the urgency of taking strong climate change policies today. When taking uncertainties into account, the desirable strength of policy (as measured by the social cost of carbon or the optimal carbon tax) would increase, not decrease,” Nordhaus wrote.

July 14, 2018

Lomborg published an article in The Australian criticising the Paris Agreement on climate change. In the article, he argues that:

“The Paris treaty, fully implemented, would achieve one hundredth of the reduction to 2C (a level at which there are still significant impacts), and hence achieve benefits worth perhaps only one tenth of 1 per cent of global GDP 100 years from now”.

Lomborg’s figures are based on a single study by Professor Richard Tol, an academic formally associated with the UK‘s premier climate science denial campaign group, the Global Warming Policy Foundation — as pointed out in a blog post by Bob Ward of the London School of Economics’ Grantham Institute. Ward points out many other errors in Lomborg’s analysis including that the Paris Agreement is not legally binding (it is), that the target to keep warming to 1.5 degrees is out of reach (many academics have concluded the target is still possible), and that coal will be cheaper than renewable energy in 2040 (in contrast with generally conservative International Energy Agency projections).

Climate-Change Policies Can Be Punishing for the Poor,” an article by Lomborg in The Wall Street Journal,  suggests that climate policies “bear an unfair burden” on “the rich world’s energy poor.” Lomborg claims the often-repeated talking point that “Policies aimed at addressing climate change can easily end up punishing the poor,” pointing a finger at Germany and citing a study by the fossil-fuel-funded Institute for Energy Research (IER), claiming that renewable energy targets and emissions caps have resulted in “energy poverty.”116Bjorn Lomborg. “Climate-Change Policies Can Be Punishing for the Poor,” The Wall Street Journal, January 4, 2018.

According to Lomborg, “Climate change has been blamed for a dizzying array of absurd woes from the dwindling number of customers at Bulgarian brothels to the death of the Loch Ness monster” as well as  “the recent assertion by Unicef’s Bangladesh head of mission that climate change leads to an increase in child marriages.”

“Focusing on what we could achieve in the future through global-warming policies takes our attention away from what we could accomplish today,” Lomborg wrote, using the spread of malaria-carrying mosquitoes as an example.

“Geoengineering means deliberately manipulating the Earth’s climate. It seems like something from science fiction. But it makes sense to think of it as a prudent and affordable insurance policy,” Lomborg writes.

According to Lomborg, renewable energy is too expensive, and this is the reason that “Climate summit after climate summit has failed to affect global temperatures.”

“Solar and wind power are still too expensive and inefficient to replace our reliance on fossil fuels. The prevailing approach, embodied by the Paris climate agreement, requires governments to try to force immature, uncompetitive green technologies on the world.

Video and transcript below. 


Do electric cars really help the environment? President Obama thinks so. So does Leonardo DiCaprio. And many others.

The argument goes like this:

Regular cars run on gasoline, a fossil fuel that pumps CO2 straight out of the tailpipe and into the atmosphere. Electric cars run on electricity. They don’t burn any gasoline at all. No gas; no CO2. In fact, electric cars are often advertised as creating “zero emissions.” But do they really? Let’s take a closer look.

First, there’s the energy needed to produce the car. More than a third of the lifetime carbon-dioxide emissions from an electric car comes from the energy used make the car itself, especially the battery. The mining of lithium, for instance, is not a green activity. When an electric car rolls off the production line, it’s already been responsible for more than 25,000 pounds of carbon-dioxide emission. The amount for making a conventional car: just 16,000 pounds.

But that’s not the end of the CO2 emissions. Because while it’s true that electric cars don’t run on gasoline, they do run on electricity, which, in the U.S. is often produced by another fossil fuel – coal. As green venture capitalist Vinod Khosla likes to point out, “Electric cars are coal-powered cars.”

The most popular electric car, the Nissan Leaf, over a 90,000-mile lifetime will emit 31 metric tons of CO2, based on emissions from its production, its electricity consumption at average U.S. fuel mix and its ultimate scrapping.

A comparable Mercedes CDI A160 over a similar lifetime will emit just 3 tons more across its production, diesel consumption and ultimate scrapping. The results are similar for a top-line Tesla, the king of electric cars. It emits about 44 tons, which is only 5 tons less than a similar Audi A7 Quattro.

So throughout the full life of an electric car, it will emit just three to five tons less CO2.  In Europe, on its European Trading System, it currently costs $7 to cut one ton of CO2. So the entire climate benefit of an electric car is about $35. Yet the U.S. federal government essentially provides electric car buyers with a subsidy of up to $7,500.

Paying $7,500 for something you could get for $35 is a very poor deal.  And that doesn’t include the billions more in federal and state grants, loans and tax write-offs that go directly to battery and electric-car makers

The other main benefit from electric cars is supposed to be lower pollution. But remember Vinod Khosla’s observation “Electric cars are coal-powered cars.”

Yes, it might be powered by coal, proponents will say, but unlike the regular car, coal plant emissions are far away from the city centers where most people live and where damage from air pollution is greatest. However, new research in Proceedings of the National Academy of Sciences found that while gasoline cars pollute closer to home, coal-fired power actually pollutes more – a lot more.

How much more?

Well, the researchers estimate that if the U.S. has 10% more gasoline cars in 2020, 870 more people will die each year from the additional air pollution. If the U.S. has 10% more electric vehicles powered on the average U.S. electricity mix, 1,617 more people will die every year from the extra pollution. Twice as many.

But of course electricity from renewables like solar and wind creates energy for electric cars without CO2. Won’t the perceived rapid ramp-up of these renewables make future electric cars much cleaner? Unfortunately, this is mostly wishful thinking. Today, the U.S. gets 14% of its electric power from renewables. In 25 years, Obama’s U.S. Energy Information Administration estimates that number will have gone up just 3 percentage points to 17%. Meanwhile, those fossil fuels that generate 65% of U.S. electricity today will still generate about 64% of it in 2040.

While electric-car owners may cruise around feeling virtuous, the reality is that the electric car cuts almost no CO2, costs taxpayers a fortune, and, surprisingly, generates more air pollution than traditional gasoline cars.

Bjorn Lomborg has been writing a daily blog during the Paris climate change conference (COP21) where he has been consistently criticizing wind and solar energy.148Giles Parkinson. “IEA says Lomborg claims on wind and solar energy are ‘rubbish’,“ RenewEconomy, December 2, 2015. URL:

“The reality is that even after two decades of climate talks, we get a meagre 0.5% of our total global energy consumption from solar and wind energy, according to the leading authority, the International Energy Agency (IEA). And 25 years from now, even with a very optimistic scenario, envisioning everyone doing all that they promise in Paris, the IEA expects that we will get just 2.4 per cent from solar and wind.” 

RenewEconomy earlier countered this claim, citing the International Energy Agency (the same source that Lomborg refers to). According to RenewEconomy, the IEA‘s reports show that “wind and solar will overtake coal as the biggest source of electricity by around 2030, and by 2040 will provide more than 8,200 terrawatt hours of electricity a year – twice as much as coal.”151Giles Parkinson. “Bjorn Lomborg, it’s time to check your numbers on wind and solar,” RenewEconomy, November 11, 2015.

“That is absolute rubbish,” Frankl told RenewEconomy at a side-event at the Paris climate talks.

Frankl point to graphs from the recent World Energy Outlook, the ones that show that the IEA, itself criticized for a conservative outlook on wind and solar, expected that wind and solar will provide 27 per cent of global electricity demand by 2040 in its most optimistic scenario.

One of the most persistent claims in the climate debate is that global warming leads to more extreme weather. This is a common concern expressed by those who fear a dangerously warming planet. President Barack Obama did so eloquently in his 2013 State of the Union Address when he talked about “the devastating impact of raging fires, and crippling drought, and more powerful storms.” Many others have offered similar sentiments.

Global warming is a problem that needs to be addressed, but exaggeration doesn’t help. It often distracts us from simple, cheaper and smarter solutions. To find those solutions, let’s address the three horsemen of the climate apocalypse to which President Obama referred.  

Historical analysis of wildfires around the world shows that since 1950 their numbers have decreased globally by 15%. Estimates published in the Proceedings of the National Academy of Sciences shows  that even with global warming, the level of wildfires will continue to decline until midcentury and won’t resume on the level of 1950 – the worst for fire – before the end of the century.

Claiming that droughts are a consequence of global warming is also wrong. The world has not seen a general increase in drought. A study published in Nature in March 2014 shows globally that there has been little change in drought over the past 60 years.

The U.N. Climate Panel in 2012 concluded: “Some regions of the world have experienced more intense and longer droughts, in particular in southern Europe and West Africa, but in some regions droughts have become less frequent, less intense, or shorter, for example, in central North America and northwestern Australia.”

And finally, the third horseman: hurricanes. Global hurricane activity today, measured by total energy, hasn’t been lower since the 1970s.

While it is likely that we will see somewhat stronger (but fewer) storms as climate change continues, damages will be lower because we’ll be better adapted. A March 2012 Nature study shows that the global damage cost from hurricanes will be 0.02% of gross domestic product by 2100 – down 50% from today’s 0.04%.

Let me make this clear: this does not mean that climate change isn’t an issue. It means that exaggerating the threat concentrates resources in the wrong areas.

Consider hurricanes (though similar points hold for wildfire and drought). If the aim is to reduce storm damage, then first focus on resilience – better building codes and better enforcement of those codes. Ending subsidies for hurricane insurance to discourage building in vulnerable zones would also help, as would investing in better infrastructure (from stronger levees to higher-capacity sewers).

These solutions are quick and comparatively cheap. Most important, they would diminish future hurricane damage, whether climate-induced or not. Had New York and New Jersey focused resources on building sea walls and adding storm doors to the subway system and making simple fixes like porous pavements, Hurricane Sandy would have caused much less damage.

In the long run, the world needs to cut carbon dioxide because it causes global warming. But if the main effort to cut emissions is through subsidies for chic renewables like wind and solar power, virtually no good will be achieved – at very high cost.

The cost of climate policies just for the European Union – intended to reduce emissions by 2020 to 20% below 1990 levels – are estimated at about $250 billion annually, or about $20 trillion over the century.  And the benefits, when estimated using a standard climate model, will reduce temperatures only by an immeasurable one-tenth of a degree Fahrenheit by the end of the century.

Even in 2040, under its most optimistic scenario, the International Energy Agency estimates that just 2.2% of the world’s energy will come from wind and solar. As is the case today, almost 80% will still come from fossil fuels. As long as green energy is more expensive than fossil fuels, growing consumer markets like those in China and India will continue mostly to be powered by them.

Solar, wind, and other renewables are still inefficient because they require subsidies of more than $120 billion a year. And even in 2040, they won’t be efficient. The International Energy Agency estimates they will still require more than $200 billion dollars annually.

Instead of pouring money into subsidies for existing, inefficient wind and solar energy, we’d be far better off supporting research and development of green energy technologies to make them cheaper, faster.

When innovation eventually makes green energy as cheap or cheaper than fossil fuel energy, everyone will use it, including China and India. Until then, let’s cool the fear mongering and make practical decisions that will help people now.

Bjorn Lomborg writes an opinion piece in The Wall Street Journal titled, “The Alarming Thing About Climate Alarmism.” Lomborg writes the United Nations Intergovernmental Panel on Climate Change’s (UNIPCC) most recent report “found that in the previous 15 years temperatures had risen 0.09 degrees Fahrenheit,” and that “the average of all models expected 0.8 degrees [Fahrenheit].

“It would be possible to go point by point through the many similar flaws in each of Lomborg’s arguments, but frankly, the book is too pitiful to merit it. It’s not that his analysis is controversial – that would be fun – but that it is deeply dissatisfying, ignorant and shallow.

Lomborg was a speaker at an environmental giving “pre-conference” organised by the conservative funding organization, the Philanthropy Roundtable. In the speech (audio here), Lomborg told the audience the only environmental investment that made economic sense was in measures to combat particulate air pollution.186What Unites Us: The Principles of American Philanthropy,” The Philanthropy Roundtable.

He promoted the findings of his Copenhagen Consensus project, which earlier that year had ranked projects on climate change as the lowest on a list of 17 potential issues to spend money on.


Lomborg hosted the Copenhagen Consensus conference, partially funded by the Danish government. Eight economists selected by Lomborg were asked to prioritize ten global problems based on a hypothetical budget of $50 billion and a timeline of five years. Based on those constraints, the panel concluded that climate change was the least cost-effective area to invest public money.

The conference was hosted through the Danish Environmental Assessment Institute, of which Lomborg was the director. When the conference was announced, five of the seven board members resigned en masse in a dispute over the event.

In 2001, Lomborg published his first major book, The Skeptical Environmentalist. In response, The Danish Ecological Council published an 225-page book titled Skeptical Questions and Sustainable Answers which documents the many errors and omissions in Lomborg’s work

The Danish Committee for Scientific Dishonesty also received numerous complaints regarding the accuracy of Lomborg’s first book. After investigating, they concluded:

“The publication is deemed clearly contrary to the standards of good scientific practice…there has been such perversion of the scientific message in the form of systematically biased representation that the objective criteria for upholding scientific dishonesty … have been met.”192Rendtorff, Jacob Dahl (2003).

Holdren, one of the Scientific American authors noted: “It is instructive that [Lomborg] apparently did not feel he could manage an adequate response by himself (In this, at least, he was correct. But he could not manage it with help, either).”195Misleading Math about the Earth,” Scientific American (sub. required), January 2002.

For his part, Lomborg sent a plea to his supporters asking for help in forming a rebuttal. It read:

“Naturally, I plan to write a rebuttal to be put on my web-site. However, I would also love your input to the issues — maybe you can contest some of the arguments in the Scientific American, alone or together with other academics. Perhaps you have good ideas to counter a specific argument. Perhaps you know of someone else that might be ideal to talk to or get to write a counter-piece.”196Misleading Math about the Earth,” Scientific American (sub. required), January 2002.

The Union of Concerned Scientists also authored a highly critical analysis of Lomborg’s first book. They state:197The Skeptical Environmentalist,” Union of Concerned Scientists. Archived December 24, 2010. URL:

“Lomborg’s book is seriously flawed and fails to meet basic standards of credible scientific analysis. The authors note how Lomborg consistently misuses, misrepresents or misinterprets data to greatly underestimate rates of species extinction, ignore evidence that billions of people lack access to clean water and sanitation, and minimize the extent and impacts of global warming due to the burning of fossil fuels and other human-caused emissions of heat-trapping gases. Time and again, these experts find that Lomborg’s assertions and analyses are marred by flawed logic, inappropriate use of statistics and hidden value judgments. He uncritically and selectively cites literature—often not peer-reviewed— that supports his assertions, while ignoring or misinterpreting scientific evidence that does not. His consistently flawed use of scientific data is, in Peter Gleick’s words ‘unexpected and disturbing in a statistician.’”

Grist magazine also asked eight leading experts to critique the book based on their particular areas of knowledge. Their critical analysis, titled “A Skeptical Look at the Skeptical Environmentalist,” thoroughly discredits many of Lomborg’s claims.198Something Is Rotten in the State of Denmark: A skeptical look at The Skeptical Environmentalist,” Grist Magazine, December 12, 2001.

Dr. Peter Gleick, a renowned American scientist, wrote another critical review of Lomborg’s Skeptical Environmentalist book in the magazine Environment. Dr. Gleick’s review, “Is the Skeptic All Wet?” catalogued numerous errors in Lomborg’s methods, data and assumptions, particularly focused on water issues.199Is the Skeptic All Wet?

Apart from the Skeptical Environmentalist and Cool It, Lomborg was also the editor of a 2010 book titled Smart Solutions to Climate Change: Comparing Costs and Benefits.209Howard Friel. “Bjørn Lomborg’s missing questions,” The Guardian, August 30, 2010. Archive .is URL:

According to a search of Google Scholar, Lomborg has primarily published articles in the area of policy and economics in relation to climate change. Many of his publications are through his Copenhagen Consensus Center via Project Syndicate, and articles at the Wall Street Journal and The Financial Times.
