You can read the talk here, but in a nutshell, Massimo was admonishing skeptics who reject the scientific consensus in fields in which they have no technical expertise - the most notable recent example of this being anthropogenic climate change, about which venerable skeptics like James Randi and Michael Shermer have publicly expressed doubts (though Shermer has since changed his mind).

I'm totally with Massimo that it seems quite likely that anthropogenic climate change is really happening. But I'm not sure I can get behind Massimo's broader argument that non-experts should defer to the expert consensus in a field.

First of all, while there are strong incentives for a researcher to find errors in other work in the field, there are strong disincentives for her to challenge the field's foundational assumptions. It will be extremely difficult for her to get other people to agree with her if she tries, and if she succeeds, she'll still be taking herself down along with the rest of the field.

The most comprehensive inquiry was the Independent Climate Change Email Review led by Sir Muir Russell, commissioned by UEA to examine the behaviour of the CRU scientists (but not the scientific validity of their work). It published its final report in July 2010

It focused on what the CRU scientists did, not what they said, investigating the evidence for and against each allegation. It interviewed CRU and UEA staff, and took 111 submissions including one from CRU itself. And it also did something the media completely failed to do: it attempted to put the actions of CRU scientists into context.

The Review went back to primary sources to see if CRU really was hiding or falsifying their data. It considered how much CRU’s actions influenced the IPCC’s conclusions about temperatures during the past millennium. It commissioned a paper by Dr Richard Horton, editor of The Lancet, on the context of scientific peer review. And it asked IPCC Review Editors how much influence individuals could wield on writing groups.

This post is about how one should deal with a denialist of Delingpole's ilk.

I saw someone I follow on Twitter retweet an update from another Twitter user called @AGW_IS_A_HOAX, which was this: "NZ #Climate Scientists Admit Faking Temperatures http://bit.ly/fHbdPI RT @admrich #AGW #Climategate #Cop16 #ClimateChange #GlobalWarming".

So I click on it. And this is how you deal with a denialist claim. You actually look into it. Here is the text of that article reproduced in full: New Zealand Climate Scientists Admit To Faking Temperatures: The Actual Temps Show Little Warming Over Last 50 YearsRead here and here. Climate "scientists" across the world have been blatantly fabricating temperatures in hopes of convincing the public and politicians that modern global warming is unprecedented and accelerating. The scientists doing the fabrication are usually employed by the government agencies or universities, which thrive and exist on taxpayer research dollars dedicated to global warming research. A classic example of this is the New Zealand climate agency, which is now admitting their scientists produced bogus "warming" temperatures for New Zealand. "NIWA makes the huge admission that New Zealand has experienced hardly any warming during the last half-century. For all their talk about warming, for all their rushed invention of the “Eleven-Station Series” to prove warming, this new series shows that no warming has occurred here since about 1960. Almost all the warming took place from 1940-60, when the IPCC says that the effect of CO2 concentrations was trivial. Indeed, global temperatures were falling during that period.....Almost all of the 34 adjustments made by Dr Jim Salinger to the 7SS have been abandoned, along with his version of the comparative station methodology."A collection of temperature-fabrication charts.

wrote a piece about James Delingpole's unfortunate appearance on the BBC program Horizon on Monday. In that piece I refered to one of his own Telegraph articles in which he criticizes renowned sceptic Dr Ben Goldacre for betraying the principles of scepticism in his regard of the climate change debate. That article turns out to be rather instructional as it highlights perfectly the difference between real scepticism and the false scepticism commonly described as denialism.

It appears that James has tremendous respect for Ben Goldacre, who is a qualified medical doctor and has written a best-selling book about science scepticism called Bad Science and continues to write a popular Guardian science column. Here's what Delingpole has to say about Dr Goldacre: Many of Goldacre’s campaigns I support. I like and admire what he does. But where I don’t respect him one jot is in his views on ‘Climate Change,’ for they jar so very obviously with supposed stance of determined scepticism in the face of establishment lies.

Scepticism is not some sort of rebellion against the establishment as Delingpole claims. It is not in itself an ideology. It is merely an approach to evaluating new information. There are varying definitions of scepticism, but Goldacre's variety goes like this: A sceptic does not support or promote any new theory until it is proven to his or her satisfaction that the new theory is the best available. Evidence is examined and accepted or discarded depending on its persuasiveness and reliability. Sceptics like Ben Goldacre have a deep appreciation for the scientific method of testing a hypothesis through experimentation and are generally happy to change their minds when the evidence supports the opposing view. Sceptics are not true believers, but they search for the truth. Far from challenging the established scientific consensus, Goldacre in Bad Science typcially defends the scientific consensus against alternative medical views that fall back on untestable positions. In science the consensus is sometimes proven wrong, and while this process is imperfect it eventually results in the old consensus being replaced with a new one.

cryonics offers almost eternal life. To its critics, cryonics is pseudoscience; the idea that we could freeze someone today in such a way that future technology might be able to re-animate them is nothing more than wishful thinking on the desire to avoid death. Many who battle nonsense dressed as science have spoken out against it: see for example Nano Nonsense and Cryonics, a 2001 article by celebrated skeptic Michael Shermer; or check the Skeptic’s Dictionary or Quackwatch entries on the subject, or for more detail read the essay Cryonics–A futile desire for everlasting life by “Invisible Flan”.

And of course the pro-cryonics people have written reams and reams of material such as Ben Best’s Scientific Justification of Cryonics Practice on why they think this is exactly as plausible as I might think, and going into tremendous technical detail setting out arguments for its plausibility and addressing particular difficulties. It’s almost enough to make you want to sign up on the spot. Except, of course, that plenty of totally unscientific ideas are backed by reams of scientific-sounding documents good enough to fool non-experts like me. Backed by the deep pockets of the oil industry, global warming denialism has produced thousands of convincing-sounding arguments against the scientific consensus on CO2 and AGW. T

Nano Nonsense and Cryonics goes for the nitty-gritty right away in the opening paragraph:To see the flaw in this system, thaw out a can of frozen strawberries. During freezing, the water within each cell expands, crystallizes, and ruptures the cell membranes. When defrosted, all the intracellular goo oozes out, turning your strawberries into runny mush. This is your brain on cryonics.This sounds convincing, but doesn’t address what cryonicists actually claim. Ben Best, President and CEO of the Cryonics Institute, replies in the comments:Strawberries (and mammalian tissues) are not turned to mush by freezing because water expands and crystallizes inside the cells. Water crystallizes in the extracellular space because more nucleators are found extracellularly. As water crystallizes in the extracellular space, the extracellular salt concentration increases causing cells to lose water osmotically and shrink. Ultimately the cell membranes are broken by crushing from extracellular ice and/or high extracellular salt concentration. […] Cryonics organizations use vitrification perfusion before cooling to cryogenic temperatures. With good brain perfusion, vitrification can reduce ice formation to negligible amounts.

what is climate change? From a scientific point of view, it is simply a statistical change in atmospheric variables (temperature, precipitation, humidity etc). It has been occurring ever since the Earth came into existence, far before humans even set foot on the planet: our climate has been fluctuating between warm periods and ice ages, with further variations within. In fact, we are living in a warm interglacial period in the middle of an ice age.

Global warming has often been portrayed in apocalyptic tones, whether from the mouth of the media or environmental groups: the daily news tell of natural disasters happening at a frightening pace, of crop failures due to strange weather, of mass extinctions and coral die-outs. When the devastating tsunami struck Southeast Asia years ago, some said it was the wrath of God against human mistreatment of the environment; when hurricane Katrina dealt out a catastrophe, others said it was because of (America’s) failure to deal with climate change. Science gives the figures and trends, and people take these to extremes.

One immediate problem with blaming climate change for every weather-related disaster or phenomenon is that it reduces humans’ responsibility of mitigating or preventing it. If natural disasters are already, as their name suggests, natural, adding the tag ‘global warming’ or ‘climate change’ emphasizes the dominance of natural forces, and our inability to do anything about it. Surely, humans cannot undo climate change? Even at Cancun, amid the carbon cuts that have been promised, questions are being brought up on whether they are sufficient to reverse our actions and ‘save’ the planet.  Yet the talk about this remote, omnipotent force known as climate change obscures the fact that, we can, and have always been, thinking of ways to reduce the impact of natural hazards. Forecasting, building better infrastructure and coordinating more efficient responses – all these are far more desirable to wading in woe. For example, we will do better at preventing floods in Singapore at tackling the problems rather than singing in praise of God.

I had the chance to sift through TIME's decades of environment coverage. I came to two conclusions: First, we were writing stories about virtually the same subjects 40 years ago as we do now. (Air pollution, endangered species, the polluted oceans, dwindling natural resources.) Second, our coverage of climate change has been really scary — by which I mean, we've emphasized the catastrophic threats of global warming in dire language.

Scientists were telling us that global warming really had the potential to wreck the future of the planet, and we wanted to get that message across to readers — even if it meant scaring the hell out of them.

According to forthcoming research by the Berkeley psychologists Robb Willer and Matthew Feinberg, when people are shown scientific evidence or news stories on climate change that emphasize the most negative aspects of warming — extinguished species, melting ice caps, serial natural disasters — they are actually more likely to dismiss or deny what they're seeing. Far from scaring people into taking action on climate change, such messages seem to scare them straight into denial.

A reporter emailed me this morning to see if I could answer a few questions about poverty. Sure I said. The emailed questions that followed?It is realistic to think that poverty can one day end?What, in your view, are the best global solutions?How urgent is it to act (in the context of climate change)?

My first reaction: thanks for asking the easy questions, lady. Was this serious? How can one possibly answer the grand questions of development in a few sentences?

It is realistic to think that poverty can one day end?In America, you can be poor but own a car, a television, and have food on the table every day. In northern Uganda, that would make you a very wealthy man.Do I see a world where nearly every household has their basic needs covered, plus some of the comforts of life? Absolutely. I imagine most places on the planet will get to what we now think of as middle-income status—perhaps $8,000 to $14,000 per head in 2011 dollars and purchasing ability. The poorest nations will probably be in those places least advantageous to trade (the landlocked, for instance) and where cultures or political systems restrict innovation and freedoms.But poverty is a relative measure, and short of a Star Trek world where you can summon food and items out of a wall unit, there will always be people who struggle to keep up.

Every time a disaster strikes, some environmentalists blame it on climate change. “It’s been such a part of the narrative of the public and political debate, particularly after Hurricane Katrina,” Roger Pielke Jr, an expert on the politics of climate change at the University of Colorado, told me.

But nothing in the scientific literature indicates that this is true. A host of recent peer-reviewed studies agree: there’s no evidence that climate change has increased the damage from natural disasters. Most likely, climate change will make disasters worse some day, but not yet.

Laurens Bouwer, of Amsterdam’s Vrije Universiteit, has recently reviewed 22 “disaster loss studies” and concludes: “Anthropogenic climate change so far has not had a significant impact on losses from natural disasters.”

Lever-Tracy confronted sociologists head on about their worrisome silence on the issue. Why have sociologists failed to address the greatest and most overwhelming challenge facing modern society? Why have the figureheads of the discipline, such as Anthony Giddens and Ulrich Beck, so far refused to apply their seminal notions of structuration and the risk society to the issue?

Earlier, we re-published an important contribution by Ulrich Beck, the world-renowned German sociologist and a Breakthrough Senior Fellow. More recently, Current Sociology published a powerful response by Reiner Grundmann of Aston University and Nico Stehr of Zeppelin University.

sociologists should not rush into the discursive arena without asking some critical questions in advance, questions such as: What exactly could sociology contribute to the debate? And, is there something we urgently need that is not addressed by other disciplines or by political proposals?

Controversy about the current state and future evolution of Himalayan glaciers has been stirred up by erroneous statements in the fourth report by the Intergovernmental Panel on Climate Change1, 2.

Variable retreat rates3, 4, 5, 6 and a paucity of glacial mass-balance data7, 8 make it difficult to develop a coherent picture of regional climate-change impacts in the region.

we report remotely-sensed frontal changes and surface velocities from glaciers in the greater Himalaya between 2000 and 2008 that provide evidence for strong spatial variations in glacier behaviour which are linked to topography and climate.

Perhaps like me, you watched the BBC Two Horizons program Monday night presented by Sir Paul Nurse, president of the Royal Society and Nobel Prize winning geneticist for his discovery of the genes of cell division.

James. He really believes there's some kind of mainstream science "warmist" conspiracy against the brave outliers who dare to challenge the consensus. He really believes that "climategate" is a real scandal. He fails to understand that it is a common practice in statistics to splice together two or more datasets where you know that the quality of data is patchy. In the case of "climategate", researchers found that indirect temperature measurements based on tree ring widths (the tree ring temperature proxy) is consistent with other proxy methods of recording temperature from before the start of the instrumental temperature record (around 1950) but begins to show a decline in temperature after that for reasons which are unclear. Actual temperature measurements however show the opposite. The researcher at the head of the climategate affair, Phil Jones, created a graph of the temperature record to include on the cover of a report for policy makers and journalists. For this graph he simply spliced together the tree ring proxy data up until 1950 with the recorded data after that using statistical techniques to bring them into agreement. What made this seem particularly dodgy was an email intercepted by a hacker in which Jones referred to this practice as a "Mike's Nature trick", referring to a paper published by his colleague Mike Hulme Michael Mann in the journal Nature. It is however nothing out of the ordinary. Delingpole and others have talked about how this "trick" was used here to "hide the decline" revealed by the other dataset, as though this was some sort of deception. The fact that all parties were found to have behaved ethically is simply further evidence of the global warmist conspiracy. Delingpole takes it further and casts aspersions on scientific consensus and the entire peer review process.

When Nurse asked Delingpole the very straightforward question of whether he would be willing to trust a scientific consensus if he required treatment for cancer, he could have said "Gee, that's an interesting question. Let me think about that and why it's different."

Himalayan glaciers are actually advancing rather than retreating, claims the first major study since a controversial UN report said they would be melted within quarter of a century.

Researchers have discovered that contrary to popular belief half of the ice flows in the Karakoram range of the mountains are actually growing rather than shrinking.

The discovery adds a new twist to the row over whether global warming is causing the world's highest mountain range to lose its ice cover.

ScienceDaily (Jan. 25, 2011) — A new scientific study shows that debris coverage -- pebbles, rocks, and debris from surrounding mountains -- may be a missing link in the understanding of the decline of glaciers. Debris is distinct from soot and dust, according to the scientists.

Experts have stated that global warming is a key element in the melting of glaciers worldwide.

With the aid of new remote-sensing methods and satellite images, we identified debris coverage to be an important contributor to glacial advance and retreat behaviors," said Bookhagen. "This parameter has been almost completely neglected in previous Himalayan and other mountainous region studies, although its impact has been known for some time.

Mojib Latif denies his research supports theory that current cold weather undermines scientific consensus on global warming

A leading scientist has hit out at misleading newspaper reports that linked his research to claims that the current cold weather undermines the scientific case for manmade global warming.

Mojib Latif, a climate expert at the Leibniz Institute at Kiel University in Germany, said he "cannot understand" reports that used his research to question the scientific consensus on climate change.He told the Guardian: "It comes as a surprise to me that people would try to use my statements to try to dispute the nature of global warming. I believe in manmade global warming. I have said that if my name was not Mojib Latif it would be global warming."

James Delingpole criticised me in this blog ("The curious double standards of Simon Singh")

Quotes from Delingpole's blog are in blue. 1.      “Yet in the opinion of Singh, the worldwide Climate Change industry is the one area where the robust scepticism and empiricism he professes to believe in just doesn’t apply.” No – where I have said this? Climate change is an area that requires extreme skepticism, i.e., questioning and challenging. However, despite all the challenges, the climate change consensus remains solid. (By the way, I thought Professor Nurse explained this to you quite clearly and slowly.)

2.      “Apparently, the job of a journalist is just to accept the word of “the scientists” and take it as read that being as they are “scientists” their word is God and it brooks no questioning or dissent.” No – where have I said this? I have been a science journalist for almost two decades and where there are differing opinions it is important to consider the overall evidence. And, having been a scientist for a short time (PhD, particle physics), I realise that nobody should be treated as a god.

Simon Singh as in the popular mathematician and bestselling author of Fermat’s Last Theorem. And also, more germanely to this story, the recent victim of an expensive libel action brought against him by the British Chiropractic Association (BCA). The BCA eventually dropped its action – but not before Singh had run up £200,000 in legal costs. Though some it his lawyers will be able to claim back, he’s still likely to lose £60,000 of his own money as a result of his brave, principled decision to fight the case rather than cave in earlier. I hugely respected him for what he did. He won a victory (albeit a financially Pyrrhic one) not just for himself but for all those of us who trade in robust opinion and who believe that English libel laws are outrageously biased in favour of vexatious complainants, which is why we have unfortunately become a haven for libel tourists, some of them representing unspeakable causes.

Among those “serious matters of public interest”, you might imagine, would be Climate Change.

Yet in the opinion of Singh, the worldwide Climate Change industry is the one area where the robust scepticism and empiricism he professes to believe in just doesn’t apply. Apparently, the job of a journalist is just to accept the word of “the scientists” and take it as read that being as they are “scientists” their word is God and it brooks no questioning or dissent. That’s it. Finished.

The Brookings Institution has a new report out by Lawrence Chandy and Geoffrey Gertz (here in PDF) on trends in global poverty

The new estimates of global poverty presented in this brief serve as a reminder of just how powerful high growth can be in freeing people from poverty. In the span of a decade, the share of the world’s population living in poverty could be cut by two-thirds, the number of countries where more than 1 in 6 people live in poverty could drop from 60 to 35, and 19 countries are poised to eliminate poverty altogether.

Of course, it is far too early to declare success in the fight against poverty. To begin with, our estimates are just that; they are not hard numbers that can be calculated in real time, and the gains we imagine might not be realized if projections of future consumption growth turn out to be overly optimistic or if the poor do not share in this growth. Moreover, even if our figures are broadly accurate, in 2015 there will still be close to 600 million people—twice the population of the United States—living on less than the meager sum of $1.25 a day. Their fates are far from secure and represent a strategic and moral failure for the rest of the world, arguably all the more so as millions of others escape poverty.

Comment by Jason on 11 April 2010: I’m from Michigan, USA. Fuel prices here are about $3.00/gal right now. Although this is really hard to afford, because of the absence of real public transportation and the need to drive your own vehicle to work, it has recently become harder because of the downturn of the economy. If you’re planning to move to the US, be prepared for the high prices, and low wages…
