Bjørn Lomborg is a political scientist, economist and the founder and president of the Copenhagen Consensus Center , a US-based think tank which originated at the Copenhagen Business School in Denmark.
According to his website , Lomborg is also an adjunct professor at the Copenhagen Business School. He received his Ph. D. in Political Science at the University of Copenhagen in 1994.
He appears regularly on global lists of influential people, including Time magazine and Esquire, he writes columns which appear in many of the highest circulating newspapers in the world.
He is best known as the author of The Skeptical Environmentalist and Cool It, two books on global warming. Notably, Lomborg does not have a background in climate science and has published no peer-reviewed articles in the area.
Lomborg's errors in his discussion of climate change have been well-documented by many sources. For example, one notable website  is dedicated to documenting his errors (the site also maintains a timeline  documenting the events leading to Lomborg's fame, and how he is regarded among his fellow Danes).
Lomborg has recently been pioneering the controversial idea  of geo-engineering to solve the issue of climate change. 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. 
Geoengineering research proponent Ken Caldeira has said “the vision of Lomborg’s Climate Consensus is 'a dystopic world out of a science fiction story … Geoengineering is not an alternative to carbon emissions reductions … If emissions keep going up and up, and you use geoengineering as a way to deal with it, it's pretty clear the endgame of that process is pretty ugly'.” 
Lomborg's Copenhagen Consensus Center  (CCC) was founded in 2006 in Denmark and in 2008 registered as a non-profit organisation in the United States. The center has attracted more than $4million in funding since 2008.
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. 
But Lomborg's “new” view on climate change, presented prominently in his new book Smart Solutions to Climate Change, isn't exactly new. He still 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.” 
At this point, Lomborg appears to be directly contradicting himself .
On December 6, 2013, three days after Lomborg wrote an op-ed for The New York Times Opinions page , The Guardian released an article entitled, “Is Bjorn Lomborg right to say fossil fuels are what poor countries need? ” 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.'
Lomborg, now known  for his distaste for solar panels due to their inefficiencies, which he states is “why you have to subsidize them,” simultaneously shuns renewables while ignoring the fact that fossil fuels receive tremendous subsidies. Contradicting himself, again it appears, Lomborg 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.” ,
April 29, 2014
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:”
“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.” 
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.” 
November 12, 2013
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.” 
“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?”

Bjorn Lomborg testified  in front of the U.S. Senate Committee on Environment & Public Works, Subcommittee on Clean Air and Nuclear Safety in a hearing titled, “Examining the Threats Posed by Climate Change: The Effects of Unchecked Climate Change on Communities and the Economy .”
April 16, 2014
Lomborg was quoted in an a web-piece entitled, “Earth Daze ,” written by news correspondent John Stossel  in Real Clear Politics, “The amazing number that most people haven't heard is, if you take all the solar panels and all the wind turbines in the world, they have (eliminated) less CO2 than what U.S. fracking (cracking rocks below ground to extract oil and natural gas) managed to do.”
Stossel writes that even if America reaches Obama's “absurd” pledge to put 1,000,000 electric vehicles on the road by 2015, the impacts of climate change would only be delayed by “one hour,” according to Lomborg, and the mitigation measure was merely a “symbolic act.” 
February 8, 2014
Lomborg published an article in USA Today's Columnists' Opinions section entitled, “Lomborg: Obama energy policy hurts African poor ,” where he suggests that investing in renewable energy, instead of gas, would let “millions of poor go unserved,” again referencing the recurring theme of 'energy poverty.' 
Lomborg publishes an op-ed in The New York Times titled, “The Poor Need Cheap Fossil Fuels ,” where he advocates maintaining the status quo of “reliable, low-cost fossil fuels, at least until we can make a global transition to a greener energy future.” 
October 20, 2013
Just a few weeks following the partnership announcement  between Slate and the American Prosperity Consensus Project, Lomborg releases a piece on Slate entitled, “Of Course the World Is Better Now Than It Was in 1900 .” Within it, he describes a “scorecard spanning 150 years ,” developed by him and “21 of the world's top economists,” to see, through standard “economic valuations,” if the world was “doing better or worse.” In the closing statement of the piece, Lomborg writes, “realists should now embrace the view that the world is doing much better … We should guide our future attention not on the basis of the scariest stories or loudest pressure groups, but on objective assessments of where we can do the most good.” 
October 7, 2013
Lomborg is quoted in a ThinkProgress article explaining “why the Copenhagen Consensus Center is launching the American Prosperity Consensus project in partnership with Slate,”
“In 2040, the United States will differ greatly from the country we know today. Demographics trends will continue to reshape it, making it an older, more ethnically diverse nation. It will also become a denser, more urban population, which will affect the way we eat, work, shop, and relax. The policies the U.S. pursues at home will also affect the role that the nation plays in the world as a dynamic society and economy. These internal and external pressures create the need for robust policy solutions that address the country’s most vexing challenges and transcend today’s hyperpartisan, short-term decision making … The American Prosperity Consensus is designed as a competition of sorts. After we determine the most pressing issues according to reader input, we will ask economists and academics to propose policy solutions that best address these challenges while enabling America’s prosperity to continue and expand. With your help and with the guidance of Nobel laureates, we will create a list of top proposals. A final ranking will emerge from ongoing online debates and from the American Prosperity Summit, to be held in May 2014.” 
Environmental communications and public health expert Robert J. Brulle , from Drexel University, told ThinkProgress that it appeared Slate has decided to no longer engage in “serious journalism,” as seen in the “gimmick” with Bjorn Lomborg. 
November 12, 2010
Lomborg appeared in the documentary film Cool It  which focused on his views regarding climate policy where he suggests “that there's a well-financed effort underfoot to spin the failure of climate action into a new political strategy for high-tech mega-investments.”
Lomborg said that “independent investors” financed the film. 
September 9, 2009
Lomborg publishes a blog post in Reuters UK's Analysis and Opinion section entitled, “We Need a Fresh Approach On Climate Change .”  In the opinion piece, Lomborg links back to the Copenhagen Consensus Center's research results , which were conducted by an “Expert Panel of five world-class economists - including three recipients of the Nobel Prize;” their duty: “to form conclusions about which solution to climate change is the most promising.” The panel concluded, “the most effective use of resources would be to invest immediately in researching marine cloud whitening technology,” a form of geoengineering.

June 18, 2009
Lomborg is listed as a guest speaker on a panel at the fifth International Congress on Mining, Oil and Energy where he was to speak on a panel with the title “Global Crisis and Sustainable Solutions: The Truth About Global Warming. ”
David Sassoon wrote a series of postings at Solve Climate on Lomborg’s media tours to the US. They are available here:
- “Global Warming’s Danish Denialist Coming to America: Part 1” 
- “Global Warming’s Danish Denialist Coming to America: Part 2” 
- “Global Warming’s Danish Denialist Coming to America: Part 3” 
- “Bjorn Lomborg Delivers Nihilist Message at Manhattan Institute Climate Talk” 
In 2007 Lomborg published his second major book skeptical about climate change titled Cool It. His book tour in Canada was sponsored by the Fraser Institute , an organization which has received $120,000  from ExxonMobil since 1998.
Alanna Mitchell, the Science Reporter for the Globe and Mail wrote a review :
“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. I remember wondering, after I interviewed Lomborg, whether he was intellectually dishonest or just not very bright. Cool It has convinced me that it doesn’t matter. Lomborg has now proved beyond a doubt that he is incapable of contributing anything of merit to scientific discourse.” 
More recently, Dr. Frank Ackerman  of Tufts University wrote a detailed and critical analysis  for the peer-reviewed journal Climatic Change , outlining the many errors and biases in Lomborg's book:
“The book is riddled with small inaccuracies, and because it displays a pervasive bias in its coverage and evaluations of climate issues. To begin with, Lomborg has a weak grasp of some of the essential details and commits elementary mistakes, with little or no citation of sources that would explain his results.” 
Lomborg is a speaker at an environmental giving “pre-conference” organised by the conservative funding organisation, the Philanthropy Roundtable . In the speech, Lomborg told the audience the only environmental investment that made economic sense was in measures to combat particulate air pollution.
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.
Professor John Quiggin  is a Senior Research Fellow of the Australian Research Council, based at the Australian National University and Queensland University of Technology. He wrote a series of articles critical of the process, participants and perceived bias of the conference. , 
He concludes that “the Copenhagen Consensus project was created as a political stunt. It was designed, in every detail, to produce a predetermined outcome. Having got the desired outcome, the organizer has shown little or no interest in pursuing any of the other issues raised by the project.”
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.”
Scientific American later published their own 10-page article,  written by four leading experts, that was critical of The Skeptical Environmentalist and which described Lomborg's work as “deeply flawed.” 
They further described Lomborg's text as having “misrepresented the actual positions of environmentalists and scientists” with an analysis that was “marred by invalidating errors that include a narrow, biased reading of the literature, an inadequate understanding of the science, and quotations taken out of context.”
John P. 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).”
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.”
“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. 
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.
According to a search of Google Scholar, Lomborg has not published any articles in the area of climate science, although he has published numerous articles on economics.
