Australian Federal Election 2016: another one for the FFS! file


An article in the Brisbane Times on 8 March 2016 clearly indicates that climate change denying right-wing nutters still rule the Liberal Party of Australia and they want to spend the Turnbull Government to spend taxpayer dollars chasing their delusions:

The NSW Liberals have formally called on the Turnbull government to conduct public debates about climate change - including whether the science is settled - in a stark reminder of the deep divisions within the party over the issue.

A motion passed at the party's state council calls on the government to "arrange and hold public debates/discussions" between scientists from the Intergovernmental Panel on Climate Change and "independent climate scientists".

The motion says the events should cover "the global warming/climate change debate"; "the claims by the IPCC"; and the statement "is all the science settled".

It proposes the first debate be held in Sydney, the second in Melbourne and "the others to take place one in each state".

Fairfax Media understands the motion passed with support of more than 70 per cent of delegates at the state council meeting held on the Central Coast last weekend.

A second motion called on the Turnbull government to hold an inquiry into Australia's engagement with the United Nations on climate change and report back to the party by mid-year.

But an amendment by NSW MLC Catherine Cusack, supported by left faction powerbroker Michael Photios, ensured the motion was sent off to the party's platform committee for consideration at a later stage.

The motions - which were debated after Prime Minister Malcolm Turnbull had left the room following his speech - reveal the level of climate change scepticism among the Liberal base in NSW.……

An examination by Dr. Sophie Lewis of Tony Abbott's climate change denialism first as a shadow minister, then as Opposition Leader and finally (albeit briefly) as Prime Minister


In addition to showing that the perception-based understanding of climate change and extremes adopted by Abbott (i.e., the Natural Variability Concept) is not fully consistent with the observed time series, I also show that it cannot be internally consistent….
It should however, be noted, that I have taken a subset of representative quotes by Prime Minister Abbott to constitute a simplified mental model of climate change, and Mr Abbott has provided many opinions of the physical science behind climate change in addition to the small selection of quotes used here.
[Lewis, S.C., Can public perceptions of Australian climate extremes be reconciled with the statistics of climate change? Weather and Climate Extremes (2015), http://dx.doi.org/10.1016/j.wace.2015.11.008i]

Some of the Abbott quotes discussed at length in the study and set out briefly here:

* During the record-breaking spring temperatures in Australia in 2013, Abbott said, "… the thing is that at some point in the future, every record will be broken, but that doesn't prove anything about climate change. It just proves that the longer the period of time, the more possibility of extreme events". Other public comments by Prime Minister Abbott about climate change and variability include that the argument behind human-caused climate change is "absolute crap", that "there doesn't appear to have been any appreciable warming since the late 1990s" and that the link between climate change and extreme Australian climate events is "complete hogwash" (Readfearn, 2014). 

Former Prime Minister Abbott's understandings of climate change and variability are not unique. Rather, these provide an encapsulation of a widely held view that the longer the period of time under consideration, the greater the possibility of extreme events. Abbott's comments are selected here for exploration as they demonstrate a widespread mental model of understanding and are capable of being highly influential. These personal understandings of climate change arise from several causes. First, the manifestation of climate change in weather and climate is typically poorly understood (Trenberth, 2011). In general, people have difficulty perceiving changes in the physicals climate system above the natural variability of local climate (Myers et al., 2012)…..

* On October 30 2013, Prime Minister Abbott stated, "… the thing is that at some point in the future, every record will be broken, but that doesn′t prove anything about climate change. It just proves that the longer the period of time, the more possibility of extreme events". 

A statistical interpretation of this statement is that the sequence of observed temperatures fails to satisfy the assumption of being identically distributed and independent. If the assumption of IID were the case, then the "possibility" of an extreme would be less likely in 2013, and in 2014, than in the early part of the observed sequence…..

* In October 2009 Prime Minister Abbott stated that the argument behind human-caused climate change was "absolute crap." Later in December 2009, Abbott stated that "there doesn't appear to have been any appreciable warming since the late 1990s" and in July 2007 that "there may even have been a slight decrease in global temperatures (the measurement data differs on this point) over the past decade". 

That is, in these statements Abbott rejected that an increasing trend in temperatures has occurred in the sequence of observations in recent years. Hence, these particular statements by Prime Minister Abbott are in apparent contradiction in terms of explaining the increase in record-breaking in the later part of the observational record. If climate change is "absolute crap" and "there doesn't appear to have been any appreciable warming" then the probability of recent record breaking should be lower with an increasing length of temperature time series.

* Prime Minister Abbott concluded in October 2013 that the link between extremes (in this case bushfires) and climate change was "complete hogwash" and that "I'm not one of those people who runs around and says every time there's a fire or a flood, that proves climate change is getting worse. Australia has had fires and floods since the beginning of time. We've had much bigger floods and fires than the ones we've recently experienced. You can hardly say they were the result of anthropic [sic] global warming." 

Hence, to hold an internally consistent viewpoint within the Natural Variability Concept, the increase in the rate of record-breaking requires either a change in the shape of the temperature probability distribution with time that can be attributed to natural climate mechanisms, or requires that record-breaking rates have increased because temperatures are auto-correlated due to natural physical climate mechanisms such as thermal feedbacks between the ocean and atmosphere, sunspots and volcanic activity (Bassett, 1992).

* This does not, however, suggest that understandings developed under the Natural Variability Concept can be readily changed by simply viewing this conceptualisation as a deficit of knowledge. For example, former Prime Minister Abbott said in July 2009 that he was "…hugely unconvinced by the so-called settled science on climate change". 

Hence, this mismatch between an individual's perceptions of the climate change and extremes, and the physical evidence of the observed and modelled climate system, is undoubtedly complex and cannot be resolved simply with a singular approach…..

What the author1 said about this study in The Guardian on 23 January 2016:

The first way to understand Abbott's claim is that in any system, the longer you wait, the more often you will see records fall. 
But Lewis points out that the exact opposite is true. 
In a system without any sort of trend, such as a random string of temperatures, the first one will be a record-breaker, by default. 
The second one will have a 50% chance of being a record-breaker. 
The third has a one in three chance of being a record breaker … and so on. 
In a very long temperature series, you should see very few records being broken, and they will break less often over time.
Unless, of course, there is a warming or cooling trend.
Alternatively, Abbott might simply have meant there was no connection between extreme heat records and climate change. 
Instead, natural variability might be to blame: natural variability includes things such as the El Niño phenomenon, which push temperature around year-to-year.
To test if that might be the case, Lewis ran a series of climate models in which the greenhouse effect was removed – so all that was left was natural variability. Unsurprisingly, in those models, high temperature records were less common than they are in reality. In other words, the record-breaking that we have seen cannot be explained by natural variation.
"It drives me mental that these sorts of statements go unaddressed," Lewis says. 
She says scientific literature generally tries to simply explain what is happening, ignoring misunderstandings in the public sphere.
"This was an attempt to bridge that gap."

Tony Abbott and his attempts to degrade scientific research in Australia


It is well known that Australian Prime Minister Tony Abbott believes that climate change science is absolute crap, but even he has exceeded expectations of what his passive-aggressive brand of climate change denialism will bring forth when he appointed self-described climate policy sceptic, Bjørn Lomborg*, as an adviser to federal government on foreign aid delivery and arranged for the Australian taxpayer to fund Lomborg to the tune of $4 million now that the Danish Government has defunded his pseudo-scientific approach to research and American donors are not enthusiastically supporting this 'homeless' think tank the Copenhagen Consensus Center Inc.

BRIEF BACKGROUND

Excerpt from one of the Lomborg Errors documents:


"The Skeptical Environmentalist" has given rise to extensive public discussion and debate, both in Denmark and internationally. There have been enthusiastic reviews in some of the world's top newspapers such as the Washington Post and the New York Times, and in The Economist.

The magazine Scientific American asked four leading experts to assess Bjørn Lomborg's treatment of their own fields: global warming, energy, population and biodiversity, devoting 11 pages to this in January 2002.

Stephen Schneider: "Global Warming, Neglecting the Complexities"

Schneider is a particularly respected researcher who has been discussing these problems for 30 years with thousands of fellow scientists and policy analysts in myriad articles and formal meetings.

Most of Bjørn Lomborg's quotes allude to secondary literature and media articles. Bjørn Lomborg uses peer-reviewed articles only when they support his rose-coloured point of view. By contrast, the authors on the Intergovernmental Panel on Climate Change (IPCC) were subjected to three rounds of audits by hundreds of external experts.

Bjørn Lomborg employs no clear and discrete distinction between various forms of probabilities. He makes frequent use of the word "plausible" but, strangely for a statistician, he never attaches any probability to what is "plausible". IPCC gives a large "range" for the majority of projections, but Bjørn Lomborg selects the least serious outcomes.

Stephen Schneider then provides a specific criticism of Bjørn Lomborg's four main arguments:

1. Climate Science: Bjørn Lomborg quotes an article in Nature (from the Hadley Center, 1989), uncritically and without the authors' caveats. BL quotes Lindzen's controversial "iris effect" as evidence that IPCC's climate range needs to be reduced by a factor of almost three. BL either fails to understand this mechanism or else omits to state that the data stem from only a few years' data in a small part of a single ocean. Extrapolating this sample to the entire globe is wrong. Similarly, he quotes a controversial Danish paper claiming that solar magnetic events can modulate cosmic radiation and produce a clear connection between global low-level cloud cover and incoming cosmic rays as an alternative to CO2 in order to explain climate change. The reason IPCC discounts this theory is "that its advocates have not demonstrated any radiative forcing sufficient to match that of much more parsimonious theories, such as anthropogenic forcing."

2. Emissions scenarios: Bjørn Lomborg assumes that over the next several decades, improved solar machines and other new technologies will crowd fossil fuels off the market, which will be done so efficiently that the IPCC scenarios vastly overestimate the chance of major increases in CO2. This is not so much analysis as wishful thinking contingent on policies capable of reinforcing the incentives for such development, and BL is opposed to such policies. No credible analyst can just assert that a fossil-fuel-intensive scenario is not "plausible" and, typically, BL gives no probability that this might occur.

3. Cost-benefit calculations: Bjørn Lomborg's most egregious distortions and feeblest analyses are his citations of cost-benefit calculations. First, he chides the governments that modified the penultimate draft of the IPCC report. But there was a reason for that modification, which downgraded aggregate cost-benefit studies: these studies fail to consider so many categories of damage held to be important by political leaders, and it is therefore not the "total cost-benefit" analysis that Bjørn Lomborg wants. Again, BL cites only a single value for climate damage - 5 trillion dollars - although the same articles indicate that climate change can vary from benefits to catastrophic losses. It is precisely because the responsible scientific community cannot rule out catastrophic outcomes at a high level of confidence that climate mitigation policies are seriously proposed. For some inexplicable reasons, BL fails to provide a range of climate damage avoided, only a range for climate policy costs. This estimate is based solely on the economics literature but ignores the findings of engineers and does not take into account pre-existing market imperfections such as energy-inefficient machinery, houses and processes. Thus, five US Dept. of Energy laboratories have suggested that such a substitution can actually reduce some emissions at below-zero costs.

4. The Kyoto Protocol: Bjørn Lomborg's invention of a 100-year regime for the Kyoto Protocol is a distortion of the climate policy process. Most analysts know that "an extended" Kyoto Protocol cannot deliver the 50% reduction in CO2 emissions needed to prevent large increases at the end of the 21st century and during the 22nd century, and that developed and developing countries alike will have to cooperate to fashion cost-effective solutions over time. Kyoto is a starting point, and yet with his 100-year projection BL would squash even this first stage.

Bjørn Lomborg's book is published by the social sciences side of Cambridge University Press. It is no wonder, then, that the reviewers failed to spot BL's unbalanced presentation of the natural science. It is a serious omission on the part of an otherwise respected publishing house that natural-science researchers were not taken on board. "Lomborg admits, 'I am not myself an expert as regards ENVIRONMENTAL PROBLEMS' - truer words are not found in the rest of the book".

John P. Holdren: "Energy: Asking the Wrong Questions"

Bjørn Lomborg's chapter on energy covers a scant 19 pages and is devoted almost entirely to attacking the belief that the world is running out of energy, a belief that BL appears to regard as part of the "environmental litany". But only a handful of environmental researchers, if any at all, believe this today. Conversely, what they do say about this topic is that we are not running out of energy, but out of environment, i.e. the capacity of air, water, soil and biota to absorb, without intolerable consequences for human well-being, the effects of energy extraction, transport, energy transformation and energy use. They also say that we are running out of the ability to manage other risks of the energy supply, such as overdependence on Middle East oil and the risk of nuclear energy systems leaking weapons materials and expertise into the hands of proliferation-prone nations or terrorists. This has been the position of the environmental researchers for decades (e.g. from 1971, 74, 76 and 77).

So whom is BL so resoundingly refuting with his treatise on the abundance of world energy resources? The professional analysts have not been arguing that the world is running out of energy, only that the world could run out of cheap oil. BL's dismissive rhetoric notwithstanding, this is not a silly question, nor one with an easy answer.

Oil is currently the most valuable of the conventional fossil fuels that have long provided the bulk of the world's energy, including almost all energy for transport. The quantity of recoverable oil resources is thought to be far less than coal and natural gas, and those reserves are located in the politically volatile Middle East. Much of the rest is located offshore and in other difficult and environmentally fragile areas. There is, accordingly, a serious technical literature, produced mainly by geologists and economists, exploring the questions of when world oil production will peak and begin to decline, and what the price might be in 2010, 2030 or 2050 - with considerable disagreement among informed professionals.

BL seems not to recognize that the transition from oil to other sources will not necessarily be a smooth one or occur at prices as low as the price of oil today. BL shows no sign of understanding why there is real debate about this among serious-minded people.

BL offers no explanation of the distinction between "proved reserves" and "remaining ultimately recoverable resources", nor of the fact that the majority of the latter category is located in the Middle East, but placidly informs us that it is "imperative for our future energy supply that this region remains reasonably peaceful" - as if that observation does not undermine any basis for complacency.

BL is right in his basic proposition that the resources of oil, oil shale, nuclear fuels and renewable energy are immense. But that is disputed by only few environmental researchers-and no well-informed ones. But his handling of the technical, economic and environmental factors that will govern the circumstances and quantities in which these resources might actually be used is superficial, muddled and often plain wrong. His mistakes include apparent misreadings and misunderstandings of statistical data, the very kinds of errors he claims are pervasive in the writings of environmentalists. By the same token, there are other elementary blunders of a type that should not be committed by any self-respecting statistician. Thus, it is wrong that measures in the developed countries have eliminated the vast majority of SO2 and NO2 from smoke from coal-burning facilities: it is only a minor proportion. Other examples are given, and when it comes to nuclear energy, plutonium is such a great security problem as regards the potential production of nuclear weapons that it may preclude use of the "breeding" approach unless a new technology is invented that is just as cheap.

BL uses precise figures, where there is no basis for such, and he produces assertions based on single citations and without detailed elaborations, which is far from representative of the literature.

Most of what is problematic about the global energy picture is not covered by BL in the chapter on energy but in the chapters dealing with air pollution, acid rain, water pollution and global warming. The latter has been devastatingly critiqued by Schneider.

There is no space to deal with the other energy-related chapters, but their level of superficiality, selectivity and misunderstandings is roughly consistent with what has been reviewed here.

"Lomborg is giving skepticism - and statisticians - a bad name."

John Bongaarts: "Population: Ignoring Its Impact"

Bjørn Lomborg's view that the number of people is not the problem is simply wrong. The global population growth rate has declined slowly, but absolute growth remains close to the very high levels observed in past decades. Any discussion of global trends is misleading without taking account of the enormous contrasts between world regions, where the poorest nations of Africa, Asia and Latin America have rapidly growing and young populations, whereas Europe, North America and Japan have virtually zero, and in some cases even negative, growth. As a consequence, all future growth will be concentrated in the developing countries, where four-fifths of the world's population lives: from 4.87 to 6.72 billion between 2000 and 2025, or just as large as the record-breaking increase in the past quarter of the (21st) century. This growth in the poorest parts of the world continues virtually unabated. The growth has led to high population density in many countries, but BL dismisses concerns about this issue, based on a simplistic and misleading calculation of density as the ratio of people to land. In Egypt this would make 88/km2, but deducting the uncultivated and unirrigated part of Egypt, it makes 2,000/km2 - no wonder Egypt has to import foodstuffs! Measured correctly, population densities have reached extremely high levels, particularly in large countries in Asia and the Middle East. This makes demands in terms of agricultural expansion on more difficult, hitherto untilled terrain, increased water consumption and a struggle for the scarce water resources between households, industry and farming. The upshot will be to make growth in food production more expensive to achieve. BL's view that increased food production is a non-issue rests heavily on the fact that foodstuffs are cheap; but BL overlooks the fact that it is large-scale subsidies to farmers, particularly in the developed countries, that keep prices artificially low.

Appreciably expanding farming will result in a reduction of woodland areas, loss of species, soil erosion, and pesticide and fertilizer run-offs. Reducing this impact is possible but costly, and would be easier if the growth in population were slower.

BL overlooks the fact that population growth contributes to poverty. First, children have to be fed, housed, clothed and educated - while economically non-productive - then jobs have to be created once they reach adulthood. Unemployment lowers wages to subsistence level. Counteracting population growth has fuelled "economic miracles" in a number of East Asian countries.

BL overlooks the fact that the favourable trend in life expectancy is due to intensive efforts on the part of governments and the international community, but despite this, 800 million are still malnourished and 1.2 billion are living in abject poverty. Population is not the main cause of the world's social, economic and environmental problems, but it is a substantial contributory factor. If future growth can be slowed down, future generations would be better off.

Thomas Lovejoy: "Biodiversity: Dismissing Scientific Progress"

In less than a page, Bjørn Lomborg discounts the value of biodiversity both as a library for the life sciences and as a provider of ecosystem services (partly due to the general absence of markets for these services). When he does get round to extinction, he confounds the process by which a species is judged to have been made extinct with estimates and projections of extinction rates. In contrast to BL's claim, the loss of species from habitat remnants is a widely documented phenomenon. A number of factual errors are highlighted. BL takes particular exception to Norman Myer's 1979 estimate that 40,000 species are being lost every year, failing to acknowledge that Myer deserves credit for being the first to point out that the number was large and at a time when it was difficult to do so accurately. Current estimates are given in terms of the increases over normal extinction rates. BL cynically spurns this method, because such estimates sound more ominous. Instead, he ought to acknowledge that this method is an improvement in the science. These rates are currently 100 to 1,000 times' the normal, and are certain to rise as natural habitats continue to dwindle.

The chapter on acid rain is equally poorly researched and presented. BL establishes that acid rain has nothing to do with urban pollution, though it is a fact that nitrogen compounds (NOx) from traffic are a major source. Errors are pointed out in BL's view of acid rain on forests.

The chapter on forests suffers from BL not knowing that FAO's data are marred by the weight of so many different definitions and methods that any statistician should know they are not valid in terms of a time series. There are errors in the figures from Indonesia in 1997. BL confuses forests with tree plantations, and asserts that the only value of forests is harvestable trees. That is analogous to valuing computer chips for their silicon content only.

It is important to know that while deforestation and acid rain are reversible, extinction of species is not.

BL entirely overlooks the fact that environmental scientists identify a problem, posit hypotheses, test them and, having reached their conclusions, suggest remedial policies. By focusing on the first and last stages in this process, BL implies incorrectly that all environmentalists do is exaggerate.


Dr Peter Raven, President of the American Association for the Advancement of Science in 2002 said of Lomborg: "...he's not an environmental scientist and he doesn't understand the fields that he's talking about so in that case, if you have a point to make and you want to get to that point, which is: everything's fine, everybody's wrong, there is no environmental problem, you just keep making that point. It's like a school exercise or a debating society, which really doesn't take into account the facts". 
"Raven said that the success of Lomborg's book 'demonstrates the vulnerability of the scientific process -- which is deliberative and hypothesis driven -- to outright misrepresentation and distortion.'"

Newsweek 21 February 2010:

Lomborg opens Cool It with a long discussion on polar bears, arguing that no more than two (of 20) groups are declining in population, that their numbers are not falling overall, and, in places where they are, that it is not a result of global (or Arctic) warming. In fact, polar-bear populations in warming regions are rising, he argues, suggesting that a warmer world will be beneficial to the bears. As Friel shows, Lomborg sourced that to a blog post and to a study that never mentioned polar bears. But he ignored the clear message of the most authoritative assessment of the bears' population trends, namely, research by the International Union for Conservation of Nature. It found that bear populations are indeed declining where the Arctic is warming. In fact, concluded the IUCN, polar-bear populations "have declined significantly" where spring temperatures have risen dramatically. It also offered an explanation for Lomborg's claim that numbers are falling most where temps are getting colder: that area happens to be where there is unregulated hunting.
For his claim that the polar-bear population "has soared," Lomborg cited a 1999 study (scroll down to the paper by Ian Stirling). But that study described declining birthrates and other threats to the bears, blaming warmer spring temperatures that cause the sea ice to break up. Overall, since the mid-1980s polar-bear numbers have fallen, which experts attribute to global warming. The source is thus not exactly the solid endorsement of Lomborg's claim about thriving polar bears that one might assume.

Climate Council 14 April 2015:

The Australian Government today announced they would contribute $4m for Danish climate contrarian Bjorn Lomborg to establish a new “consensus centre” at the University of Western Australia.

In the face of deep cuts to the CSIRO and other scientific research organisations, it's an insult to Australia’s scientific community.

As the Climate Commission, we were abolished by the Abbott Government in 2013 on the basis that our $1.5 million annual operating costs were too expensive. We relaunched as the Climate Council after thousands of Australians chipped in to the nation’s biggest crowd-funding campaign…

It seems extraordinary that the Climate Commission, which was composed of Australia’s best climate scientists, economists and energy experts, was abolished on the basis of a lack of funding and yet here we are three years later and the money has become available to import a politically-motivated think tank to work in the same space.

This is why the work of the Climate Council is so important - to counter this continuing ideological attempt at deceiving the Australian public.

Mr Lomborg’s views have no credibility in the scientific community. His message hasn’t varied at all in the last decade and he still believes we shouldn't take any steps to mitigate climate change. When someone is unwilling to adapt their view on the basis of new science or information, it's usually a sign those views are politically motivated. 

 Bjørn Lomborg states he is a director of the Copenhagen Consensus Center, adjunct professor at University of Western Australia, and visiting professor at Copenhagen Business School.
He further states that he has an M.A. in political science (University of Aarhus) and a Ph.D. in political science (University of Copenhagen).
His degrees are in social science and not in any of the scientific disciplines which inform credible climate research.

900 more science jobs forecast to go by June 2015 in Abbott's Australia


ABC Rural 26 November 2014:

The CSIRO is set to lose one staff member in five over the next two years.
The effect of the Federal Government's cut of $114 million is now becoming clearer, with at least four regional research sites under threat.
National organiser for the CSIRO Staff Association, part of the CPSU, Paul Girdler, says 878 staff are to be cut over two years, until June 2015.
"It's over 100 more than originally forecast.
"Over two years, the CSIRO is losing 21.5 per cent of its workforce, or one in five jobs.
"This new analysis demonstrates the cuts are even worse than when they were announced."
Given the cuts last year, the total tally is 1,400 jobs at the Science Organisation.
Now it includes 36 scientists in agriculture and biosecurity fields, the majority in Canberra and Southern Queensland, while 75 scientists in Mineral Resources and Energy, and 71 in Land and Water, are targetted.
Mr Girdler says the futures of regional CSIRO sites are already threatened.
"The ones we have particular concerns about (include) Griffith in the Riverina.
"CSIRO has already announced it would close by 2016. We're trying to fight to keep that site open, but we have concerns.
"Three other sites will close unless they receives additional funding. One is Atherton in north Queensland, which is Ecosystem Science research.
"And two in NSW, the Radio Astronomy sites at Narrabri and Parkes."…..
"As of this week, two thirds of the people directly affected by the 2014 announced changes have been advised of or have completed their transition.  For the remaining positions that need to be identified and discussed with staff, leaders will be talking to individuals as soon as possible to resolve uncertainty.
"I appreciate these changes have been very difficult for all and I can assure you that your leadership team is committed to supporting staff through this time of change," says Mr Roy.

UPDATE

The Age 2 December 2014:

A world-leading CSIRO chemist who was  tipped to win a Nobel prize has been made redundant.
In September, the same month San Thang was nominated as a frontrunner for the illustrious prize in chemistry, he also ceased working as a senior researcher for the national science organisation, which has been hemorrhaging staff since June last year following severe budget cuts and a restructure.
As compensation, Dr Thang, who has worked at CSIRO for almost 30 years, was given an unpaid honorary fellowship. He continues to work at his former laboratory in Clayton, mainly supervising PhD students…..
A CSIRO spokesman confirmed Dr Thang had been made redundant as part of these changes.
As a direct consequence of the federal government slashing $115 million from CSIRO's funding over four years in the May budget, the organisation is expected to lose another 400 researchers and support staff by mid next year in addition to 300 positions being cut as part of an internal restructure.
This month, the CSIRO staff association released new data showing the size and scale of the job cuts were larger than expected, reporting that 878 positions were to be cut by June 2015.
But another CSIRO spokesman said the organisation did not expect a major variation from the number of staff reductions it announced earlier this year, around 720 positions.

Australian Prime Minister Tony Abbott forgot that science is evidence-based


With science removed from its ministerial portfolio list, the dismantling of a number of science-based advisory bodies, savage cuts to science funding and climate change denialism rampant in its ranks – surely the Abbott Government must have expected this when it had the gall to hand out the Prime Minister’s Prizes For Science as though science mattered to this federal government.


The Guardian 30 October 2014:

Tony Abbott received a frosty response from scientists after he called on them to lobby Labor and Greens MPs to support the government’s plan for a medical research fund.
Abbott, speaking at the prime minister’s science awards in Canberra on Wednesday night, reiterated a message from his speech at last year’s awards when he said the government should be judged “not by its titles but by its performance”.
“I hope our performance has at least passed muster over the past 12 months,” the prime minister said, to a smattering of applause at the Parliament House awards ceremony.
“That was desultory applause, but at least it was some,” Abbott said, in response to the tepid response from the assembled scientists….

This exchange has been carefully omitted from the official transcript of Abbott’s speech which can be found here.

This is not the first time scientists attending these awards have signalled their dissatisfaction by failing to bring their hands together in unison en masse.

After last year’s prize giving The Guardian noted on 31 October 2013:

“It’s been remarked upon that we don’t have a minister for science as such in the new government and I know that there are people in the room who may have been momentarily dismayed by that,” Abbott said.
“But let me tell you that the United States does not have a secretary for science and no nation on Earth has been as successful and innovative as the United States. I’d say to all of you please, judge us by our performance, not by our titles.”
Abbott’s speech, which drew a smattering of applause from the audience, provoked a mixed reaction.

Readfearn picks apart Tony Abbott's favoured climate science denier


Graham Readfearn writing in The Guardian, on Abbott Government chief business adviser Maurice Newman’s claim that the world should prepare for global cooling which was published in The Australian on 14 August 2014:

Growing evidence?


At the beginning of the column, Newman claims a recent article in the journal Astronomy & Astrophysics “adds to growing evidence that climate change is determined by the sun, not humans”.
The problem with this statement is that the journal article in question did not even consider the interactions between the sun and long-term climate change.
Even one of the climate sceptic websites that recently featured this research, said: “Unfortunately, it was beyond the scope of this paper to address the potential impact of solar activity on climate.”
Professor Steve Sherwood, director of the Climate Change Research Centre at the University of New South Wales, explains:
Evidence that the sun influences climate has decreased, not increased. About a decade ago calculations showed the sun caused about 10 per cent of the warming observed since the late 1800s, but it is now estimated to be only about 5 per cent. This new paper does not change these estimates at all, it is only an attempt to extend the sunspot record back to times before direct observations began a few hundred years ago. The paper makes no mention of climate, because it does not have any new implications for climate.
Since 1980, during which time we have seen strong warming, solar output has if anything declined slightly. In fact, it is looking increasingly doubtful that the sun even had much to do with the so-called “little ice age”, which most mainstream scientists used to attribute to the minimum in sunspot activity at roughly the same time, but now looks to have been caused mainly by volcanic eruptions.
Newman tells his readers that experiments at the Large Hadron Collider (LHC) in Europe had “validated” a hypothesis from Danish physicist Professor Henrik Svensmark that “the sun alters the climate” by interacting with cosmic rays.
The former ASX chairman makes it sound like a done deal. But what did the lead author of that research actually think? Did it “confirm the hypothesis” that the sun alters the climate “by influencing cosmic ray influx and cloud formation” as Newman had claimed?
Professor Jasper Kirby, who led the research, said at the time “it actually says nothing about a possible cosmic-ray effect on clouds and climate, but it’s a very important first step”.
So that’s a no, then (minor nit, as Nature also explained, the experiment didn’t use the LHC, as Newman had claimed, but rather the same bit of kit – a particle accelerator - that feeds the LHC).

Newman and the IPCC


Newman wrote that the United Nations Intergovernmental Panel on Climate Change “and its acolytes” tend to “pay scant attention” to science that might “relegate human causes” as the driver of climate change.
Professor Sherwood was a Lead Author on the latest IPCC report chapter to look at these cosmic ray claims. He told me:
In writing the relevant section of the report, we examined Svensmark’s work along with many other relevant studies. It is quite clear that the evidence suggesting that cosmic rays influence cloud cover, does not hold up to scrutiny. The IPCC is quite comprehensive in assessing the scientific literature and making an overall assessment. If there is any cherry-picking going on, it is by the so-called skeptics, who typically focus on a tiny handful of papers and often draw unwarranted inferences from them not made by the authors themselves, as Newman has done in this case.

Sly misrepresentation


Newman name checks other organisations and scientists to try and bolster his argument.
He quotes work by “leading British climate scientist Mike Lockwood, of Reading University” to try and convince readers that the sun might be the dominant driver of the climate.
But Newman doesn’t mention what Lockwood actually thinks about these claims of cosmic rays or the sun dictating global temperatures
After his work was misrepresented in the British press last year, Lockwood responded on the website Carbon Brief:

So what do we think the effect of a return to Maunder minimum conditions on global mean temperatures would be? The answer is very little.
In a paper with scientists from the Met Office’s Hadley Centre, we used an energy balance model to show the slowing in anthropogenic global warming associated with decline in solar irradiance to Maunder minimum levels.
We found the likely reduction in warming by 2100 would be between 0.06 and 0.1 degrees Celsius, a very small fraction of the warming we’re due to experience as a result of human activity.
I sent Newman’s article to Lockwood to ask if he felt his work and his views were being fairly represented. Suffice to say he’s not too happy. He wrote:
The wording in the quote you sent me is a very sly misrepresentation. As a scientist I try to write sentences that are unambiguous ... but this is deliberately ambiguous to make it look like I am saying something that I certainly am not. I have never, ever written anything whatsoever about the “year without summer”, so I have never ever connected it to solar variability and the Dalton minimum. So if I trim the sentence down to “... Mike Lockwood, of Reading University, found 24 occasions in the past 10,000 years when the sun was declining as it is now, but could find none where the decline was as fast. He says a return of the Dalton Minimum (1790-1830) is ‘more likely than not’” Then I would be happy - but the addition of the phrase which included “the year without summer” makes it look like I am connecting that year to the Dalton minimum which I certainly am not. There is absolutely no credible evidence whatsoever that the “year without summer” was either caused by low solar activity or was in any way significant as an indicator of global climate trend.
I also asked Lockwood what he thought of Newman’s claim that there was “growing evidence that climate change is determined by the sun, not humans”. Lockwood said:
[This claim] is, frankly, scientifically ludicrous. There are a few papers that use inadequate statistical techniques to claim a link between global temperatures and solar activity. Proper significance testing against an appropriate noise model invariably shows that the probability that these sun-global climate connections are purely coincidental is extremely high and that they have been selected whilst a very large number of counter examples have been ignored. This is bad science: it’s equivalent to finding on albino rabbit and declaring all rabbits are albino.
There have been many studies, including ones that I have been involved in, that show the solar influence on global mean surface temperatures is extremely small. I personally think there is evidence for some interesting effects in winter (and only in winter, and there are compelling scientific reasons why only in winter) in locations that are strongly influenced by the northern hemisphere jet stream.
However these effects are re-distributions of temperature and so, for example, if Europe suffers a cold winter, Greenland has a warmer one. Hence these are regional and season climate changes and quite distinct from global climate changes.
That looks like one less Christmas card for Maurice Newman.
But there’s still more to go at here. Newman quotes a University of Pennsylvania professor of psychology Philip Tetlock as saying: “When journal reviewers, editors and funding agencies feel the same way about a course, they are less likely to detect and correct potential logical or methodological bias.”
The quote is actually a decade old and comes from an article published in the journal Political Psychology.
Newman probably got it trawling the blogs of climate sceptics (an article discussing the paper was reposted on the UK’s Global Warming Policy Foundation website earlier this month), which is where, in my view, he probably gets most of his ideas about climate science.
You might think, given the context of the article, that Tetlock was talking about environmental science or climate change.
But no. The Tetlock article was discussing his concerns about the preservation of the discipline of “political psychology”. Most of the article is discussing issues around war and peace and racism.

A close encounter of the unique kind



One day early last year, Australian comet hunter Robert H. McNaught spotted something unusual from his post at the Siding Spring Observatory in the foothills of the Warrumbungle Mountains, NSW….
Comet Siding Spring is especially interesting because of its formation in the Oort cloud during the early days of the solar system, making it a "long period" comet with an orbit of millions of years. What's more, it is believed to be what comet specialists call a virgin - one that has never reached the inner solar system.
As a result, its icy nucleus (the "dirty snowball" at the core of a comet) has never been thawed and reshaped, like those of comets that pass by more regularly.
"We've studied the nuclei of comets before but never a long-period comet from the Oort cloud," Zurek said. "The comet may well be bringing us primordial material unchanged since the creation of the solar system."

The BBC getting it right on climate change reporting and comment



The coverage of science by the BBC continues to be a hotly debated issue. One of the key findings of the report which still resonates today is that there is at times an:

  “… ‘over-rigid’ (as Professor Jones described it) application of the Editorial Guidelines on impartiality in relation to science coverage, which fails to take into account what he regards as the ‘non-contentious’ nature of some stories and the need to avoid giving ‘undue attention to marginal opinion’. Professor Jones cites … the existence of man-made climate change as [an] example of this point.”

This is a matter of training and ongoing shared editorial judgement. The Trust notes that seminars continue to take place and that nearly 200 senior staff have attended workshops which set out that impartiality in science coverage does not simply lie in reflecting a wide range of views, but depends on the varying degree of prominence (due weight) such views should be given.

The Trust wishes to emphasise the importance of attempting to establish where the weight of scientific agreement may be found and make that clear to audiences. The Trust also would like to reiterate that, as it said in 2011, “This does not mean that critical opinion should be excluded. Nor does it mean that scientific research shouldn’t be properly scrutinised.” The BBC has a duty to reflect the weight of scientific agreement but it should also reflect the existence of critical views appropriately. Audiences should be able to understand from the context and clarity of the BBC’s output what weight to give to critical voices.

The BBC has developed excellence in science broadcasting, and generalists who may be unfamiliar with these areas and where the weight of scientific agreement may lie should make the most of the resources of the BBC – for example its Science Editor, the BBC’s science experts and the workshops and seminars discussed in the Executive report.
Judging the weight of scientific agreement correctly will mean that the BBC avoids the ‘false balance’ between fact and opinion identified by Professor Jones. The Trust welcomes the Executive’s decision to hold a further course this year for staff who may not have been in position at the time of the previous workshops and as a refresher on a complex area.

Scientist bites back at climate change denialist claims


Mother Jones 24 January 2014:
In 2012—after writers for National Review and a prominent conservative think tank accused him of fraud and compared him to serial child molester Jerry Sandusky—climate scientist Michael Mann took the bold step of filing a defamation suit. The defendants moved to have the case thrown out, citing a Washington, DC, law that shields journalists from frivolous litigation. But on Wednesday, DC Superior Court Judge Frederick Weisberg rejected the motion, opening the way for a trial.
Although public figures like Mann have to clear a high bar to prove defamation, Weisberg argued that the scientist's complaint may pass the test. And he brushed aside the defendants' claims that the fraud allegations were "pure opinion," which is protected by the First Amendment:
Accusing a scientist of conducting his research fraudulently, manipulating his data to achieve a predetermined or political outcome, or purposefully distorting the scientific truth are factual allegations. They go to the heart of scientific integrity. They can be proven true or false. If false, they are defamatory. If made with actual malice, they are actionable.
Weisberg's order is just the latest in a string of setbacks that have left the climate change skeptics' case in disarray. Earlier this month, Steptoe & Johnson, the law firm representingNational Review and its writer, Mark Steyn, withdrew as Steyn's counsel. According to two sources with inside knowledge, it also plans to drop National Review as a client.
The lawyers' withdrawal came shortly after Steyn—a prominent conservative pundit who regularly fills in as host of Rush Limbaugh's radio show—publicly attacked the former judge in the case, Natalia Combs Greene, accusing her of "stupidity" and "staggering" incompetence. Mann's attorney, John B. Williams, suspects this is no coincidence. "Any lawyer would be taken aback if their client said such things about the judge," he says. "That may well be why Steptoe withdrew."
Steyn's manager, Melissa Howes, acknowledged that his commentary "did not go over well."* But Steyn maintains it was his decision to part ways with his attorneys.......
Order made in MICHAEL E. MANN, PH.D. Plaintiff, v. NATIONAL REVIEW, INC. et. al., Defendants, Case No. 2012 CA 8263 B, Judge Frederick H. Weisberg:
