However, as I read the story and the findings it is based upon, some questions crept into my mind. I relate them not out of any desire to discredit the study, which is enterprising and newsworthy, but simply as a warning to parents and policymakers not to go overboard.

from a dense academic article that hasn’t been published or peer reviewed. At this stage, there isn’t even a working paper detailing how the results were arrived at: just a set of slides. Why is this important? Because economics is a disputatious subject, and surprising empirical findings invariably get challenged by rival groups of researchers. The authors of the paper include two rising stars of the economics profession—Berkeley’s Emmanuel Saez and Harvard’s Raj Chetty—both of whom have reputations for careful and rigorous work. However, many other smart researchers have had their findings overturned. That is how science proceeds. Somebody says something surprising, and others in the field try to knock it down. Sometimes they succeed; sometimes they don’t. Until that Darwinian process is completed, which won’t be for another couple of years, at least, the new findings should be regarded as provisional.

There are already three heavyweight groups that could be considered the official keepers of the world's climate data. Each publishes its own figures that feed into the UN's Intergovernmental Panel on Climate Change. Nasa's Goddard Institute for Space Studies in New York City produces a rolling estimate of the world's warming. A separate assessment comes from another US agency, the National Oceanic and Atmospheric Administration (Noaa). The third group is based in the UK and led by the Met Office. They all take readings from instruments around the world to come up with a rolling record of the Earth's mean surface temperature. The numbers differ because each group uses its own dataset and does its own analysis, but they show a similar trend. Since pre-industrial times, all point to a warming of around 0.75C.

You might think three groups was enough, but Muller rolls out a list of shortcomings, some real, some perceived, that he suspects might undermine public confidence in global warming records. For a start, he says, warming trends are not based on all the available temperature records. The data that is used is filtered and might not be as representative as it could be. He also cites a poor history of transparency in climate science, though others argue many climate records and the tools to analyse them have been public for years.

Then there is the fiasco of 2009 that saw roughly 1,000 emails from a server at the University of East Anglia's Climatic Research Unit (CRU) find their way on to the internet. The fuss over the messages, inevitably dubbed Climategate, gave Muller's nascent project added impetus. Climate sceptics had already attacked James Hansen, head of the Nasa group, for making political statements on climate change while maintaining his role as an objective scientist. The Climategate emails fuelled their protests. "With CRU's credibility undergoing a severe test, it was all the more important to have a new team jump in, do the analysis fresh and address all of the legitimate issues raised by sceptics," says Muller.

This latest point is where Muller faces his most delicate challenge. To concede that climate sceptics raise fair criticisms means acknowledging that scientists and government agencies have got things wrong, or at least could do better. But the debate around global warming is so highly charged that open discussion, which science requires, can be difficult to hold in public. At worst, criticising poor climate science can be taken as an attack on science itself, a knee-jerk reaction that has unhealthy consequences. "Scientists will jump to the defence of alarmists because they don't recognise that the alarmists are exaggerating," Muller says.

The Berkeley Earth project came together more than a year ago, when Muller rang David Brillinger, a statistics professor at Berkeley and the man Nasa called when it wanted someone to check its risk estimates of space debris smashing into the International Space Station. He wanted Brillinger to oversee every stage of the project. Brillinger accepted straight away. Since the first meeting he has advised the scientists on how best to analyse their data and what pitfalls to avoid. "You can think of statisticians as the keepers of the scientific method, " Brillinger told me. "Can scientists and doctors reasonably draw the conclusions they are setting down? That's what we're here for."

For the rest of the team, Muller says he picked scientists known for original thinking. One is Saul Perlmutter, the Berkeley physicist who found evidence that the universe is expanding at an ever faster rate, courtesy of mysterious "dark energy" that pushes against gravity. Another is Art Rosenfeld, the last student of the legendary Manhattan Project physicist Enrico Fermi, and something of a legend himself in energy research. Then there is Robert Jacobsen, a Berkeley physicist who is an expert on giant datasets; and Judith Curry, a climatologist at Georgia Institute of Technology, who has raised concerns over tribalism and hubris in climate science.

Robert Rohde, a young physicist who left Berkeley with a PhD last year, does most of the hard work. He has written software that trawls public databases, themselves the product of years of painstaking work, for global temperature records. These are compiled, de-duplicated and merged into one huge historical temperature record. The data, by all accounts, are a mess. There are 16 separate datasets in 14 different formats and they overlap, but not completely. Muller likens Rohde's achievement to Hercules's enormous task of cleaning the Augean stables.

The wealth of data Rohde has collected so far – and some dates back to the 1700s – makes for what Muller believes is the most complete historical record of land temperatures ever compiled. It will, of itself, Muller claims, be a priceless resource for anyone who wishes to study climate change. So far, Rohde has gathered records from 39,340 individual stations worldwide.

Publishing an extensive set of temperature records is the first goal of Muller's project. The second is to turn this vast haul of data into an assessment on global warming.

The big three groups – Nasa, Noaa and the Met Office – work out global warming trends by placing an imaginary grid over the planet and averaging temperatures records in each square. So for a given month, all the records in England and Wales might be averaged out to give one number. Muller's team will take temperature records from individual stations and weight them according to how reliable they are.

This is where the Berkeley group faces its toughest task by far and it will be judged on how well it deals with it. There are errors running through global warming data that arise from the simple fact that the global network of temperature stations was never designed or maintained to monitor climate change. The network grew in a piecemeal fashion, starting with temperature stations installed here and there, usually to record local weather.

Among the trickiest errors to deal with are so-called systematic biases, which skew temperature measurements in fiendishly complex ways. Stations get moved around, replaced with newer models, or swapped for instruments that record in celsius instead of fahrenheit. The times measurements are taken varies, from say 6am to 9pm. The accuracy of individual stations drift over time and even changes in the surroundings, such as growing trees, can shield a station more from wind and sun one year to the next. Each of these interferes with a station's temperature measurements, perhaps making it read too cold, or too hot. And these errors combine and build up.

This is the real mess that will take a Herculean effort to clean up. The Berkeley Earth team is using algorithms that automatically correct for some of the errors, a strategy Muller favours because it doesn't rely on human interference. When the team publishes its results, this is where the scrutiny will be most intense.

Despite the scale of the task, and the fact that world-class scientific organisations have been wrestling with it for decades, Muller is convinced his approach will lead to a better assessment of how much the world is warming. "I've told the team I don't know if global warming is more or less than we hear, but I do believe we can get a more precise number, and we can do it in a way that will cool the arguments over climate change, if nothing else," says Muller. "Science has its weaknesses and it doesn't have a stranglehold on the truth, but it has a way of approaching technical issues that is a closer approximation of truth than any other method we have."

It might not be a good sign that one prominent climate sceptic contacted by the Guardian, Canadian economist Ross McKitrick, had never heard of the project. Another, Stephen McIntyre, whom Muller has defended on some issues, hasn't followed the project either, but said "anything that [Muller] does will be well done". Phil Jones at the University of East Anglia was unclear on the details of the Berkeley project and didn't comment.

Elsewhere, Muller has qualified support from some of the biggest names in the business. At Nasa, Hansen welcomed the project, but warned against over-emphasising what he expects to be the minor differences between Berkeley's global warming assessment and those from the other groups. "We have enough trouble communicating with the public already," Hansen says. At the Met Office, Peter Stott, head of climate monitoring and attribution, was in favour of the project if it was open and peer-reviewed.

Peter Thorne, who left the Met Office's Hadley Centre last year to join the Co-operative Institute for Climate and Satellites in North Carolina, is enthusiastic about the Berkeley project but raises an eyebrow at some of Muller's claims. The Berkeley group will not be the first to put its data and tools online, he says. Teams at Nasa and Noaa have been doing this for many years. And while Muller may have more data, they add little real value, Thorne says. Most are records from stations installed from the 1950s onwards, and then only in a few regions, such as North America. "Do you really need 20 stations in one region to get a monthly temperature figure? The answer is no. Supersaturating your coverage doesn't give you much more bang for your buck," he says. They will, however, help researchers spot short-term regional variations in climate change, something that is likely to be valuable as climate change takes hold.

Despite his reservations, Thorne says climate science stands to benefit from Muller's project. "We need groups like Berkeley stepping up to the plate and taking this challenge on, because it's the only way we're going to move forwards. I wish there were 10 other groups doing this," he says.

Muller's project is organised under the auspices of Novim, a Santa Barbara-based non-profit organisation that uses science to find answers to the most pressing issues facing society and to publish them "without advocacy or agenda". Funding has come from a variety of places, including the Fund for Innovative Climate and Energy Research (funded by Bill Gates), and the Department of Energy's Lawrence Berkeley Lab. One donor has had some climate bloggers up in arms: the man behind the Charles G Koch Charitable Foundation owns, with his brother David, Koch Industries, a company Greenpeace called a "kingpin of climate science denial". On this point, Muller says the project has taken money from right and left alike.

No one who spoke to the Guardian about the Berkeley Earth project believed it would shake the faith of the minority who have set their minds against global warming. "As new kids on the block, I think they will be given a favourable view by people, but I don't think it will fundamentally change people's minds," says Thorne. Brillinger has reservations too. "There are people you are never going to change. They have their beliefs and they're not going to back away from them."

The participants who lived long, happy lives "were not cynical rebels and loners" but accomplished people who were satisfied with their lives. Many knew that worrying is sometimes a good thing. The authors also looked at a study of Medicare patients that found that "neuroticism was health-protective."

spending 30 minutes at least four times a week expending energy at a moderate to intense level is "good up-to-date medical advice but poor practical advice."

Being active in middle age was most important to health and longevity in the study. But rather than vow to do something to get in shape (like jogging) and then hate it and not stick with it, find something you like to do."We looked at those who stayed active," Friedman says. "It wasn't the kids on sports teams. It's the ones who had activities at one point and had the pattern of keeping them ... They were doing stuff that got them out of the chair ... whether it was gardening, walking the dog or going to museums."

One of the best childhood personality predictors of longevity was conscientiousness — "qualities of a prudent, persistent, well-organized person, like a scientist or professor — somewhat obsessive and not at all carefree,"

the most obvious reason "is that conscientious people do more things to protect their health and engage in fewer activities that are risky."

"What characterized the people who thrived is a combination of their own persistence and dependability and the help of other people," Friedman says. The young adults who were thrifty, persistent, detail-oriented and responsible lived the longest.

Those with the most career success were the least likely to die young. Those who moved from job to job without a clear progression were less likely to have long lives than those with increasing responsibilities.

"continually productive men and women lived much longer than the laid-back comrades. ... This production orientation mattered more than their social relationships or their sense of happiness or well-being."

those who were most engaged in pursuing their goals.

a sexually satisfying and happy marriage is a very good indicator of future health and long life," but being single for a woman can be just as healthy as being in a marriage, especially if she has other fulfilling social relationships.

The married men in the study lived the longest. Single men outlived remarried men but didn't live as long as married men. Among women, the number who divorced their husbands and stayed single lived nearly as long as steadily married women."Being divorced was much less harmful to a women's health," the authors say.

even if on average, an investment in higher education yields a good, say 10 percent, rate of return, it does not follow that adding to existing investments will yield that return, partly for reasons outlined above. The authors (Pedro Carneiro, James Heckman, and Edward Vytlacil) make that point explicitly, stating “Some marginal expansions of schooling produce gains that are well below average returns, in general agreement with the analysis of Charles Murray.”  (p.29)

Once the economy improves, and history tells us it will improve within our lifetimes, those who already have a college degree under their belts will be better equipped to take advantage of new employment opportunities than those who don’t. Perhaps not because of the actual knowledge obtained through their degrees, but definitely as an offset to the social stigma that still exists for those who do not attend college. A college degree may not help a young person secure professional work immediately – so new graduates spend a few years waiting tables until the right opportunity comes along. So what? It’s probably good for them. But they have 40-50 years in the workforce ahead of them and need to be forward-thinking if they don’t want to wait tables for that entire time. If we stop encouraging all young people to view college as both a goal and a possibility, and start weeding out those whose “prior academic records suggest little likelihood of academic success” which, let’s face it, will happen in larger proportions in poorer schools, then in 20 years we’ll find that efforts to reduce socioeconomic gaps between minorities and non-minorities have been seriously undermined.

Bet you a lot of those janitors with PhDs are from the humanities, in particular ethic studies, film studies,…basket weaving courses… or non-economics social sciences, eg., sociology, anthropology of never heard of country….There should be a buyer beware warning on all those non-quantitative majors that make people into sophisticated malcontent complainers!

This article also presumes that the purpose of higher education is merely to train one for a career path and enhance future income. This devalues the university, turning it into a vocational training institution. There’s nothing in this data that suggests that they are “sophisticated complainers”; that’s an unwarranted inference.

it was mentioned that the Bill and Melinda Gates Foundation would like 80% of American youth to attend and graduate from college. It is a nice thought in many ways. As a teacher and professor, intellectually I am all for it (if the university experience is a serious one, which these days, I don’t know).

students’ expectations in attending college are not just intellectual; they are careerist (probably far more so)

This employment issue has more to do with levels of training and subsequent levels of expectation. When a Korean student emerges from 20 years of intense study with a university degree, he or she reasonably expects a “good” job — which is to say, a well-paying professional or managerial job with good forward prospects. But here’s the problem. There does not exist, nor will there ever exist, a society in which 80% of the available jobs are professional, managerial, comfortable, and well-paid. No way.

Korea has a number of other jobs, but some are low-paid service work, and many others — in factories, farming, fishing — are scorned as 3-D jobs (difficult, dirty, and dangerous). Educated Koreans don’t want them. So the country is importing labor in droves — from China, Vietnam, Cambodia, the Philippines, even Uzbekistan. In the countryside, rural Korean men are having such a difficult time finding prospective wives to share their agricultural lifestyle that fully 40% of rural marriages are to poor women from those other Asian countries, who are brought in by match-makers and marriage brokers.

And these two books arrive at a time, unlike the early 1990s, when universities are, like many students, backed into a fiscal corner. Taylor writes of walking into a meeting one day and learning that Columbia’s endowment had dropped by “at least” 30 percent. Simply brushing off calls for reform, however strident and scattershot, may no longer be an option.

The labor system, for one thing, is clearly unjust. Tenured and tenure-track professors earn most of the money and benefits, but they’re a minority at the top of a pyramid. Nearly two-thirds of all college teachers are non-tenure-track adjuncts like Matt Williams, who told Hacker and Dreifus he had taught a dozen courses at two colleges in the Akron area the previous year, earning the equivalent of about $8.50 an hour by his reckoning. It is foolish that graduate programs are pumping new Ph.D.’s into a world without decent jobs for them. If some programs were phased out, teaching loads might be raised for some on the tenure track, to the benefit of undergraduate education.

it might well be time to think about vetoing Olympic-quality athletic ­facilities and trimming the ranks of administrators. At Williams, a small liberal arts college renowned for teaching, 70 percent of employees do something other than teach.

But Hacker and Dreifus go much further, all but calling for an end to the role of universities in the production of knowledge. Spin off the med schools and research institutes, they say. University presidents “should be musing about education, not angling for another center on antiterrorist technologies.” As for the humanities, let professors do research after-hours, on top of much heavier teaching schedules. “In other occupations, when people feel there is something they want to write, they do it on their own time and at their own expense,” the authors declare. But it seems doubtful that, say, “Battle Cry of Freedom,” the acclaimed Civil War history by Princeton’s James McPherson, could have been written on the weekends, or without the advance spadework of countless obscure monographs. If it is false that research invariably leads to better teaching, it is equally false to say that it never does.

Hacker’s home institution, the public Queens College, which has a spartan budget, commuter students and a three-or-four-course teaching load per semester. Taylor, by contrast, has spent his career on the elite end of higher education, but he is no less disillusioned. He shares Hacker and Dreifus’s concerns about overspecialized research and the unintended effects of tenure, which he believes blocks the way to fresh ideas. Taylor has backed away from some of the most incendiary proposals he made last year in a New York Times Op-Ed article, cheekily headlined “End the University as We Know It” — an article, he reports, that drew near-universal condemnation from academics and near-universal praise from everyone else. Back then, he called for the flat-out abolition of traditional departments, to be replaced by temporary, “problem-centered” programs focusing on issues like Mind, Space, Time, Life and Water. Now, he more realistically suggests the creation of cross-­disciplinary “Emerging Zones.” He thinks professors need to get over their fear of corporate partnerships and embrace efficiency-enhancing technologies.

It is not news that America is a land of haves and have-nots. It is news that colleges are themselves dividing into haves and have-nots; they are becoming engines of inequality. And that — not whether some professors can afford to wear Marc Jacobs — is the real scandal.

The whole business of scientific publishing is murky and sometimes who you know counts more than what you know in order to get your foot into the 'club'. Even Maddox alluded to the existence of such an 'exclusive' club:Brimble, who used to "take luncheon" at the Athenaeum in London most days, preferred to carry a bundle of manuscripts with him in the pocket of his greatcoat and pass them round among his chums "taking coffee" in the drawing-room after lunch. I set up a more systematic way of doing the job when I became editor in April 1966.

. Is the problem less with the paper and publishing process than the tendency of commentators (whether on blogs or elsewhere) to seize on particular findings as the new “truth” — and for public not attuned to the tussles of science to swallow such proclamations?

its only because of the blogosphere immediately seizing on every new paper as proof that we think there’s an issue with the peer-review process. For the scientists involved, this was a useful exercise in thinking about this problem, and moved the ball forwards rather than backwards overall. But we had to put up with way too much crap in the blogosphere in between the time when the paper was published and these rebuttals came out.

The idea that increased energy efficiency can increase energy consumption at the macro-economic level strikes many as a new idea, or paradoxical, but it was first observed in 1865 by British economist William Stanley Jevons, who pointed out that Watt's more efficient steam engine and other technical improvements that increased the efficiency of coal consumption actually increased rather than decreased demand for coal. More efficient engines, Jevons argued, would increase future coal consumption by lowering the effective price of energy, thus spurring greater demand and opening up useful and profitable new ways to utilize coal. Jevons was proven right, and the reality of what is today known as "Jevons Paradox" has long been uncontroversial among economists.

Economists have long observed that increasing the productivity of any single factor of production -- whether labor, capital, or energy -- increases demand for all of those factors. This is one of the basic dynamics of economic growth. Luddites who feared there would be fewer jobs with the emergence of weaving looms were proved wrong by lower price for woven clothing and demand that has skyrocketed (and continued to increase) ever since. And today, no economist would posit that an X% improvement in labor productivity would lead directly to an X% reduction in employment. In fact, the opposite is widely expected: labor productivity is a chief driver of economic growth and thus increases in employment overall. There is no evidence, the report points out, that energy is any different, as per capita energy consumption everywhere on earth continues to rise, even as economies become more efficient each year.

There have been attempts in the past to make the system more rational and less redundant, and to shrink the portion of it that undertakes scholarly research, but they have not met with much success, and not just because of bureaucratic resistance by the interested parties. Large-scale, decentralized democratic societies are not very adept at generating neat, rational solutions to messy situations. The story line on education, at this ill-tempered moment in American life, expresses what might be called the Noah’s Ark view of life: a vast territory looks so impossibly corrupted that it must be washed away, so that we can begin its activities anew, on finer, higher, firmer principles. One should treat any perception that something so large is so completely awry with suspicion, and consider that it might not be true—especially before acting on it.

Both sides are anxious to see how the field of the biology of politics will be viewed in 50 years — if it has indeed been lumped in with pseudosciences like phrenology or if it has become a new platform for widespread, interdisciplinary study. Meanwhile, the fascination — and vitriol — will likely remain. "The notion of where political ideology comes from has never been contested," says Bruce Bimber, a professor at University of California, Santa Barbara, who tackles this topic in graduate seminars. "It's always been a settled assumption that it is the product of socialization and life experience, and this research has come along saying, 'Wait a minute, wait a minute. We might have had this partly wrong all along.'"

Universities are also being used as flag carriers for national economic ambitions - driving forward modernisation plans. For some it's been a spectacularly fast rise. According to the OECD, in the 1960s South Korea had a similar national wealth to Afghanistan. Now it tops international education league tables and has some of the highest-rated universities in the world. The Pohang University of Science and Technology in South Korea was only founded in 1986 - and is now in the top 30 of the Times Higher's global league table, elbowing past many ancient and venerable institutions. It also wants to compete on an international stage so the university has decided that all its graduate programmes should be taught in English rather than Korean.

governments want to use universities to upgrade their workforce and develop hi-tech industries.

"Universities are being seen as a key to the new economies, they're trying to grow the knowledge economy by building a base in universities," says Professor Altbach. Families, from rural China to eastern Europe, are also seeing university as a way of helping their children to get higher-paid jobs. A growing middle-class in India is pushing an expansion in places. Universities also stand to gain from recruiting overseas. "Universities in the rich countries are making big bucks," he says. This international trade is worth at least $50 billion a year, he estimates, the lion's share currently being claimed by the US.

Technology, much of it hatched on university campuses, is also changing higher education and blurring national boundaries.

It raises many questions too. What are the expectations of this Facebook generation? They might have degrees and be able to see what is happening on the other side of the world, but will there be enough jobs to match their ambitions? Who is going to pay for such an expanded university system? And what about those who will struggle to afford a place?

The success of the US system is not just about funding, says Professor Altbach. It's also because it's well run and research is effectively organised. "Of course there are lots of lousy institutions in the US, but overall the system works well."
