Global Warming

Global Warming Again.

As the global warming matter chugs along, more more evidence of the manipulation of data is coming to light.

Although it has been emerging for seven years or more, one of the most extraordinary scandals of our time has never hit the headlines. Yet another little example of it lately caught my eye when, in the wake of those excited claims that 2014 was “the hottest year on record”, I saw the headline on a climate blog: “Massive tampering with temperatures in South America”. The evidence on Notalotofpeopleknowthat, uncovered by Paul Homewood, was indeed striking.
Puzzled by those “2014 hottest ever” claims, which were led by the most quoted of all the five official global temperature records – Nasa’s Goddard Institute for Space Studies (Giss) – Homewood examined a place in the world where Giss was showing temperatures to have risen faster than almost anywhere else: a large chunk of South America stretching from Brazil to Paraguay.
Noting that weather stations there were thin on the ground, he decided to focus on three rural stations covering a huge area of Paraguay. Giss showed it as having recorded, between 1950 and 2014, a particularly steep temperature rise of more than 1.5C: twice the accepted global increase for the whole of the 20th century.
But when Homewood was then able to check Giss’s figures against the original data from which they were derived, he found that they had been altered.

Some interesting graphics here.

I follow this story on a skeptic blog and Steve McIntyre’s blog.

Both are currently tearing apart an absurd recent paper that has serious statistical errors. Steve is a statistician.

A new paper in Nature by Jochem Marotzke and Piers Forster: ‘Forcing, feedback and internal variability in global temperature trends’[i] investigates the causes of the mismatch between climate models that simulate a strong increase in global temperature since 1998 and observations that show little increase, and the influence of various factors on model-simulated warming over longer historical periods. I was slightly taken aback by the paper, as I would have expected either one of the authors or a peer reviewer to have spotted the major flaws in its methodology. I have a high regard for Piers Forster, who is a very honest and open climate scientist, so I am sorry to see him associated with a paper that I think is very poor, even as co-author (a position that perhaps arose through him supplying model forcing data to Marotzke) and therefore not bearing primary responsibility for the paper’s shortcomings.

This is embarrassing as many are attacking the methods with what sound like valid arguments.

Even Nature has begun to recognize trouble in the alarmist world.

Despite the continued increase in atmospheric greenhouse gas concentrations, the annual-mean global temperature has not risen in the twenty-first century 1, 2, challenging the prevailing view that anthropogenic forcing causes climate warming. Various mechanisms have been proposed for this hiatus in global warming3, 4, 5, 6, but their relative importance has not been quantified, hampering observational estimates of climate sensitivity. Here we show that accounting for recent cooling in the eastern equatorial Pacific reconciles climate simulations and observations. We present a novel method of uncovering mechanisms for global temperature change by prescribing, in addition to radiative forcing, the observed history of sea surface temperature over the central to eastern tropical Pacific in a climate model.

The story is getting harder to defend but, grant money being what it is, there is still a strong motive to try to keep the ball rolling, even uphill.

The Michael Mann lawsuit against Mark Steyn and National Review is still chugging along as Mann seems to have nine lives in this matter.

Steyn comes to Washington Tuesday for a hearing at the D.C. Court of Appeals. Michael Mann, a climate scientist at Penn State, filed the lawsuit against Steyn, National Review, space policy and tech analyst Rand Simberg and the Libertarian-bent Competitive Enterprise Institute (CEI) in 2012.

All parties have lawyered up. They all have different legal representation with the exception of Simberg, who is clumped in with CEI.

It is hard for me to take this seriously but there are enough scientifically illiterate judges to keep Mann’s suit alive.

Steyn insists Mann is waiting out the clock so that everyone he’s suing will be good and broke if they ever get remotely near the prospect of a trial. The journalist, however, is plowing ahead, raising money and prepping himself for a trial he’s dying to see happen.

The case is already on its second judge — the first one applied for “senior status” (meaning she’ll work part time and get full pay) and was accepted. The second, says Steyn, seems to be more on top of things, but has been unable to restore a timely process.

Mann appears to be following a “law fare” strategy.

”If this guy Dr. Mann feels he’s being defamed then he should, like Oscar Wilde, get in court and have the manner settled. There is no right to a speedy trial…but you know, defamation is serious and more injurious to one’s reputation than bouncing a check for $30 at the general store. It’s more injurious than a parking ticket, than doing 45 in a 30 mile speed limit. [There’s the right to a speedy trial], but not for defamation. Nuts to that.”

Last summer, a “lukewarmer” scientist named Roger Peilke had the misfortune to encounter the angry left when he accepted a job at the left wing site called five thirty eight.

Roger Pielke Jr. said Monday that he left FiveThirtyEight, ending a short-lived but turbulent stint with the site launched by Nate Silver earlier this year.

Pielke, a professor of environmental studies at the University of Colorado, told Discover Magazine that after editors at the site “showed some reluctance” in publishing his work, he told FiveThirtyEight managing editor Mike Wilson that “it was probably best that we part ways.”

Reluctance was not exactly the proper term. Hysteria was more like it.

“Disinformer!” the Daily Kos screamed. “One of the country’s leading tricksters on climate change,” charged the Huffington Post. “Inaccurate and misleading,” was ThinkProgress’s measured verdict. Even that doyen of professionalism and sworn enemy of hyperbole, Michael Mann, weighed in, knocking his foe for his “pattern of sloppiness.” The pile-on was as predictable as it was unjust. At root, Pielke’s biggest crimes are to have walked at slightly different pace than his peers and to have refused to bow to the president. Pielke accepts the IPCC’s view of the climate-change question but suggests in parallel that man’s response is unlikely to have a “perceptible impact on the climate for many decades” and that civilization should thus adapt to, rather than attempt to prevent, change.

Pielke quickly left. He now has begun a new blog called The Climate Fix.

The alarmist hysteria grows more acute as the evidence piles up that they are wrong and, perhaps, even lying.

Global Warming and Cooling.

by

I have been frustrated by the antics of the AGW alarmists. Scientific American, for example, has lost whatever reputation it once had for objective science. (pdf) In an another example, the actions of Michael Mann should make for an interesting discovery in his suit against Mark Steyn.

Today, I find a nice discussion of global warming and cooling over the past epoch. The Greenland ice cores are, or should be, the gold standard of temperature measurement. For example.

Summary:
Records of past temperature, precipitation, atmospheric trace gases, and other aspects of climate and environment derived from ice cores drilled on glaciers and ice caps around the world. Parameter keywords describe what was measured in this data set. Additional summary information can be found in the abstracts of papers listed in the data set citations.

Now, to the data.

Global Warming ended 15 years ago

by

There is still considerable talk about global warming, or as it is now termed, “climate change.” California is about to destroy a large part of what is left of its economy by initiating a new “Cap and Trade” program that will spike energy costs and drive more employers from the state. New reports are casting more doubt on the reality of “climate change” and now there is more information that warming ended in 1997. The past two years have shown a definite cooling trend.

The world stopped getting warmer almost 16 years ago, according to new data released last week.

The figures, which have triggered debate among climate scientists, reveal that from the beginning of 1997 until August 2012, there was no discernible rise in aggregate global temperatures.

This means that the ‘plateau’ or ‘pause’ in global warming has now lasted for about the same time as the previous period when temperatures rose, 1980 to 1996. Before that, temperatures had been stable or declining for about 40 years.

There is even new debate among climate scientists.

Some climate scientists, such as Professor Phil Jones, director of the Climatic Research Unit at the University of East Anglia, last week dismissed the significance of the plateau, saying that 15 or 16 years is too short a period from which to draw conclusions.

Others disagreed. Professor Judith Curry, who is the head of the climate science department at America’s prestigious Georgia Tech university, told The Mail on Sunday that it was clear that the computer models used to predict future warming were ‘deeply flawed’.

Even Prof Jones admitted that he and his colleagues did not understand the impact of ‘natural variability’ – factors such as long-term ocean temperature cycles and changes in the output of the sun. However, he said he was still convinced that the current decade would end up significantly warmer than the previous two.

California, of course, is not going to wait to see if the trend continues with cooling.

Oct 2 (Reuters Point Carbon) – California Governor Jerry Brown has signed two bills related to the use of revenue raised through the sale of carbon allowances, although details of how the money will be spent won’t be determined until next year.

The bills are the first to address the estimated $660 million and $3 billion in revenue that will be generated during the first year of California’s carbon cap-and-trade scheme, which begins in January.

The first bill creates a new account for the revenue to be deposited into, and directs the Department of Finance and the California Air Resources Board (ARB) to develop an investment plan for the funds.

That plan, expected to be released in the spring of 2013, will be submitted for approval to the legislature as part of the governor’s budget and will be reviewed and updated on an annual basis.

It doesn’t matter that the state is going broke. Left wing pieties still rule California.

Virginity of global warming activist questioned.

by

During all the argument about global warming that has gone on over the past decade, warming activists have questioned the motives of defenders of traditional energy sources, implying they are all funded by fossil fuel companies. The motives of those warning of the risks of global warming have rarely been questioned, implying they are only worried about the planet and nothing so crass as accepting money for their efforts.

Now, it seems, they had normal acquisitive instincts, as well. And some of them have done quite well, I might add.

NASA records released to resolve litigation filed by the American Tradition Institute reveal that Dr. James E. Hansen, an astronomer, received approximately $1.6 million in outside, direct cash income in the past five years for work related to — and, according to his benefactors, often expressly for — his public service as a global warming activist within NASA.

This does not include six-figure income over that period in travel expenses to fly around the world to receive money from outside interests. As specifically detailed below, Hansen failed to report tens of thousands of dollars in global travel provided to him by outside parties — including to London, Paris, Rome, Oslo, Tokyo, the Austrian Alps, Bilbao, California, Australia and elsewhere, often business or first-class and also often paying for his wife as well — to receive honoraria to speak about the topic of his taxpayer-funded employment, or get cash awards for his activism and even for his past testimony and other work for NASA.

Oh, Oh. Normal instincts after all. This will set the sainthood movement back a few years. We already know about Al Gore, of course.

Does this sound familiar ?

The science community is now closing in on an example of scientific fraud at Duke University. The story sounds awfully familiar.

ANIL POTTI, Joseph Nevins and their colleagues at Duke University in Durham, North Carolina, garnered widespread attention in 2006. They reported in the New England Journal of Medicine that they could predict the course of a patient’s lung cancer using devices called expression arrays, which log the activity patterns of thousands of genes in a sample of tissue as a colourful picture. A few months later, they wrote in Nature Medicine that they had developed a similar technique which used gene expression in laboratory cultures of cancer cells, known as cell lines, to predict which chemotherapy would be most effective for an individual patient suffering from lung, breast or ovarian cancer.
 
At the time, this work looked like a tremendous advance for personalised medicine—the idea that understanding the molecular specifics of an individual’s illness will lead to a tailored treatment.

This would be an incredible step forward in chemotherapy. Sensitivity to anti-tumor drugs is the holy grail of chemotherapy.

Unbeknown to most people in the field, however, within a few weeks of the publication of the Nature Medicine paper a group of biostatisticians at the MD Anderson Cancer Centre in Houston, led by Keith Baggerly and Kevin Coombes, had begun to find serious flaws in the work.
 
Dr Baggerly and Dr Coombes had been trying to reproduce Dr Potti’s results at the request of clinical researchers at the Anderson centre who wished to use the new technique. When they first encountered problems, they followed normal procedures by asking Dr Potti, who had been in charge of the day-to-day research, and Dr Nevins, who was Dr Potti’s supervisor, for the raw data on which the published analysis was based—and also for further details about the team’s methods, so that they could try to replicate the original findings.

The raw data is always the place that any analysis of another’s work must begin.

Dr Potti and Dr Nevins answered the queries and publicly corrected several errors, but Dr Baggerly and Dr Coombes still found the methods’ predictions were little better than chance. Furthermore, the list of problems they uncovered continued to grow. For example, they saw that in one of their papers Dr Potti and his colleagues had mislabelled the cell lines they used to derive their chemotherapy prediction model, describing those that were sensitive as resistant, and vice versa. This meant that even if the predictive method the team at Duke were describing did work, which Dr Baggerly and Dr Coombes now seriously doubted, patients whose doctors relied on this paper would end up being given a drug they were less likely to benefit from instead of more likely.

In other words, the raw data was a mess. The results had to be random.
