Freeman Dyson: the last 10 years have proven climate change models wrong

Apologetics and the progress of science
Apologetics and the progress of science

This interview with liberal scientist Freeman Dyson appeared in the UK Register.


The life of physicist Freeman Dyson spans advising bomber command in World War II, working at Princeton University in the States as a contemporary of Einstein, and providing advice to the US government on a wide range of scientific and technical issues.

He is a rare public intellectual who writes prolifically for a wide audience. He has also campaigned against nuclear weapons proliferation.

At America’s Oak Ridge National Laboratory, Dyson was looking at the climate system before it became a hot political issue, over 25 years ago. He provides a robust foreword to a report written by Intergovernmental Panel on Climate Change cofounder Indur Goklany on CO2 – a report published[PDF] today by the Global Warming Policy Foundation (GWPF).

An Obama supporter who describes himself as “100 per cent Democrat,” Dyson says he is disappointed that the President “chose the wrong side.” Increasing CO2 in the atmosphere does more good than harm, he argues, but it is not an insurmountable crisis. Climate change, he tells us, “is not a scientific mystery but a human mystery. How does it happen that a whole generation of scientific experts is blind to obvious facts?”


What has happened in the past 10 years is that the discrepancies between what’s observed and what’s predicted have become much stronger. It’s clear now the models are wrong, but it wasn’t so clear 10 years ago. I can’t say if they’ll always be wrong, but the observations are improving and so the models are becoming more verifiable.

[…]It’s very sad that in this country, political opinion parted [people’s views on climate change]. I’m 100 per cent Democrat myself, and I like Obama. But he took the wrong side on this issue, and the Republicans took the right side.

Is carbon dioxide as bad as the politicians say?


To any unprejudiced person reading this account, the facts should be obvious: that the non-climatic effects of carbon dioxide as a sustainer of wildlife and crop plants are enormously beneficial, that the possibly harmful climatic effects of carbon dioxide have been greatly exaggerated, and that the benefits clearly outweigh the possible damage.

I consider myself an unprejudiced person and to me these facts are obvious. But the same facts are not obvious to the majority of scientists and politicians who consider carbon dioxide to be evil and dangerous. The people who are supposed to be experts and who claim to understand the science are precisely the people who are blind to the evidence.

[…]The scientists and politicians who have been blindly demonizing carbon dioxide for 37 years will one day open their eyes and look at the evidence.”

E. Calvin Beisner had more to say about beneficial effects of CO2 on agriculture in an article on the Stream.

He writes:

To call CO2 “carbon pollution” is not only bad chemistry and bad toxicology but also bad biology. Carbon dioxide is essential to all plant growth. The higher its concentration, the better plants grow. Below 170 ppm, plants die. At the roughly 280 ppm at the start of the Industrial Revolution, plants are “sucking air,” so to speak — barely getting enough. At today’s 400 ppm, plants grow much better — so much better that a study by researchers at the Technische Universität München found forests around the world growing up to 70 percent faster today than 50 years ago because of it. Earth is literally greening because of added CO2.

Plants will grow still better as CO2 concentration continues to rise. Thousands of empirical studies, as opposed to mere models, have found that, on average, for every doubling of CO2 concentration in the atmosphere, there is about a 35 percent increase in the efficiency of plant growth. Plants grow better in wetter and drier soils and in warmer and colder temperatures, widening their ranges and increasing their adaptability to climate changes, reducing the risk of biodiversity loss. They make better use of soil nutrients, better resist diseases and pests, and improve the ratio of fruit to fiber.

The consequence is more food for plant-eaters and eaters of plant eaters — i.e., for pretty much everything. Most importantly, it means more affordable food for the world’s poor.

A review of the refereed literature on the subject found “the … monetary value of this benefit amount[ed] to a total sum of $3.2 trillion over the 50-year period 1961–2011. Projecting the monetary value … forward … reveals it will likely bestow an additional $9.8 trillion on crop production between now and 2050.”

So honest, well-informed discussion of any policy — cap and trade, “carbon tax,” renewable mandates, etc. — to reduce CO2 emissions should first recognize the benefits of increasing its concentration in the atmosphere, not just for people but for all animals. Any rationale for reducing emissions must prove that they exact a cost that outweighs this benefit.

Ah, but being honest about the benefits would not allow our democratic socialist betters to have the platform they need to convince us to let them rule us, and control our lives down to the temperatures in our homes, what cars we drive and how much we can drive.


New study shows that the medieval warming extended far and wide

From the UK Daily Mail.


Current theories of the causes and impact of global warming have been thrown into question by a new study which shows that during medieval times the whole of the planet heated up.

It then cooled down naturally and there was even a ‘mini ice age’.

A team of scientists led by geochemist Zunli Lu from Syracuse University in New York state, has found that contrary to the ‘consensus’, the ‘Medieval Warm Period’ approximately 500 to 1,000 years ago wasn’t just confined to Europe.

In fact, it extended all the way down to Antarctica – which means that the Earth has already experience global warming without the aid of human CO2 emissions.

At present the Intergovernmental Panel on Climate Change (IPCC) argues that the Medieval Warm Period was confined to Europe – therefore that the warming we’re experiencing now is a man-made phenomenon.

However, Professor Lu has shown that this isn’t true – and the evidence lies with a rare mineral called ikaite, which forms in cold waters.

‘Ikaite is an icy version of limestone,’ said Lu. ‘The crystals are only stable under cold conditions and actually melt at room temperature.’

It turns out the water that holds the crystal structure together – called the hydration water – traps information about temperatures present when the crystals formed.

This finding by Lu’s research team establishes, for the first time, ikaite as a reliable way to study past climate conditions.

The scientists studied ikaite crystals from sediment cores drilled off the coast of Antarctica. The sediment layers were deposited over 2,000 years.

The scientists were particularly interested in crystals found in layers deposited during the ‘Little Ice Age,’ approximately 300 to 500 years ago, and during the Medieval Warm Period before it.

Both climate events have been documented in Northern Europe, but studies have been inconclusive as to whether the conditions in Northern Europe extended to Antarctica.

Lu’s team found that in fact, they did.

What that means is that the Medieval Warming Period was not local to Northern Europe, but extended all the way to Antarctica, as well. Now you might be asking yourself “how could medieval knights riding around on horseback cause global warming? Wouldn’t they have to be driving SUVs and drilling for oil and generally do nasty capitalist things like that?” Yes, they would. But they weren’t. And so this clearly shows that the warming and cooling of the Earth has nothing whatsoever to do with CO2 emissions. Whatever will the socialists do now to trick people into voting for higher gas prices?

16 scientists explain why global warming is not a threat

Perhaps the most inconvenient fact is the lack of global warming for well over 10 years now. This is known to the warming establishment, as one can see from the 2009 “Climategate” email of climate scientist Kevin Trenberth: “The fact is that we can’t account for the lack of warming at the moment and it is a travesty that we can’t.” But the warming is only missing if one believes computer models where so-called feedbacks involving water vapor and clouds greatly amplify the small effect of CO2.

The lack of warming for more than a decade—indeed, the smaller-than-predicted warming over the 22 years since the U.N.’s Intergovernmental Panel on Climate Change (IPCC) began issuing projections—suggests that computer models have greatly exaggerated how much warming additional CO2 can cause. Faced with this embarrassment, those promoting alarm have shifted their drumbeat from warming to weather extremes, to enable anything unusual that happens in our chaotic climate to be ascribed to CO2.


Although the number of publicly dissenting scientists is growing, many young scientists furtively say that while they also have serious doubts about the global-warming message, they are afraid to speak up for fear of not being promoted—or worse. They have good reason to worry. In 2003, Dr. Chris de Freitas, the editor of the journal Climate Research, dared to publish a peer-reviewed article with the politically incorrect (but factually correct) conclusion that the recent warming is not unusual in the context of climate changes over the past thousand years. The international warming establishment quickly mounted a determined campaign to have Dr. de Freitas removed from his editorial job and fired from his university position. Fortunately, Dr. de Freitas was able to keep his university job.

This is not the way science is supposed to work, but we have seen it before—for example, in the frightening period when Trofim Lysenko hijacked biology in the Soviet Union. Soviet biologists who revealed that they believed in genes, which Lysenko maintained were a bourgeois fiction, were fired from their jobs. Many were sent to the gulag and some were condemned to death.

Why is there so much passion about global warming, and why has the issue become so vexing that the American Physical Society, from which Dr. Giaever resigned a few months ago, refused the seemingly reasonable request by many of its members to remove the word “incontrovertible” from its description of a scientific issue? There are several reasons, but a good place to start is the old question “cui bono?” Or the modern update, “Follow the money.”

Alarmism over climate is of great benefit to many, providing government funding for academic research and a reason for government bureaucracies to grow. Alarmism also offers an excuse for governments to raise taxes, taxpayer-funded subsidies for businesses that understand how to work the political system, and a lure for big donations to charitable foundations promising to save the planet. Lysenko and his team lived very well, and they fiercely defended their dogma and the privileges it brought them.

Read the whole thing! This is a must-read.

UPDATE: My friend Neil Simpson has found another recent study showing that there has been no significant global warming for 15 years – and the numbers come from the British Met Office, and the University of East Anglia (home of Climategate).

New study : Earth’s climate is not as sensitive to carbon dioxide as IPCC claims

ECM sent me this article from the Economist concerning some recent research that was published in the prestigious peer-reviewed journal Science.


Climate science is famously complicated, but one useful number to keep in mind is “climate sensitivity”. This measures the amount of warming that can eventually be expected to follow a doubling in the atmospheric concentration of carbon dioxide. The Intergovernmental Panel on Climate Change, in its most recent summary of the science behind its predictions, published in 2007, estimated that, in present conditions, a doubling of CO2 would cause warming of about 3°C, with uncertainty of about a degree and a half in either direction.

[…]But a paper published in this week’s Science, by Andreas Schmittner of Oregon State University, suggests it is not. In Dr Schmittner’s analysis, the climate is less sensitive to carbon dioxide than was feared.

Existing studies of climate sensitivity mostly rely on data gathered from weather stations, which go back to roughly 1850. Dr Schmittner takes a different approach. His data come from the peak of the most recent ice age, between 19,000 and 23,000 years ago. His group is not the first to use such data (ice cores, fossils, marine sediments and the like) to probe the climate’s sensitivity to carbon dioxide. But their paper is the most thorough. Previous attempts had considered only small regions of the globe. He has compiled enough information to make a credible stab at recreating the climate of the entire planet.

[…]The group’s most likely figure for climate sensitivity is 2.3°C, which is more than half a degree lower than the consensus figure, with a 66% probability that it lies between 1.7° and 2.6°C. More importantly, these results suggest an upper limit for climate sensitivity of around 3.2°C.

I think that it is a good thing for the reputation of scientists that articles like this can be published at all. I have lost a lot of confidence in government-funded science lately, especially when the conclusion of the government-funded research supports the need for more government and high taxes.

In case you missed my recent post on the newly-release Climategate e-mails, then you should read that to see how biased climate scientists can be.

Here are the latest surface temperature measurements.

Climategate 2.0: Leaked e-mails show scientists intended to deceive public

The UK Telegraph’s James Delingpole writes in the Wall Street Journal.


Last week, 5,000 files of private email correspondence among several of the world’s top climate scientists were anonymously leaked onto the Internet. Like the first “climategate” leak of 2009, the latest release shows top scientists in the field fudging data, conspiring to bully and silence opponents, and displaying far less certainty about the reliability of anthropogenic global warming theory in private than they ever admit in public.

The scientists include men like Michael Mann of Penn State University and Phil Jones of the University of East Anglia, both of whose reports inform what President Obama has called “the gold standard” of international climate science, the Intergovernmental Panel on Climate Change (IPCC).

[…][A]t least one scientist involved—Mr. Mann—has confirmed that the emails are genuine, as were the first batch released two years ago.

[…]Consider an email written by Mr. Mann in August 2007. “I have been talking w/ folks in the states about finding an investigative journalist to investigate and expose McIntyre, and his thus far unexplored connections with fossil fuel interests. Perhaps the same needs to be done w/ this Keenan guy.” Doug Keenan is a skeptic and gadfly of the climate-change establishment. Steve McIntyre is the tenacious Canadian ex-mining engineer whose dogged research helped expose flaws in Mr. Mann’s “hockey stick” graph of global temperatures.

One can understand Mr. Mann’s irritation. His hockey stick, which purported to demonstrate the link between man-made carbon emissions and catastrophic global warming, was the central pillar of the IPCC’s 2001 Third Assessment Report, and it brought him near-legendary status in his community. Naturally he wanted to put Mr. McIntyre in his place.

The sensible way to do so is to prove Mr. McIntyre wrong using facts and evidence and improved data. Instead the email reveals Mr. Mann casting about for a way to smear him. If the case for man-made global warming is really as strong as the so-called consensus claims it is, why do the climategate emails show scientists attempting to stamp out dissenting points of view? Why must they manipulate data, such as Mr. Jones’s infamous effort (revealed in the first batch of climategate emails) to “hide the decline,” deliberately concealing an inconvenient divergence, post-1960, between real-world, observed temperature data and scientists’ preferred proxies derived from analyzing tree rings?

What I can’t believe is that we’ve spent billions of dollars funding myths. They lied because they were being paid by the government to lie. The government wanted a crisis that would require more government control over businesses and consumers. And the scientists found that evidence in their “research”, because that’s what the government was paying them to do.
