Leading Climate Scientist Defects: No Longer Believes in the 'Consensus'

One of the world's most eminent climate scientists - for several decades a warmist - has defected to the climate sceptic camp.

Lennart Bengtsson - a Swedish climatologist, meteorologist, former director of the Max Planck Institute for Meteorology in Hamburg and winner, in 2006, of the 51st IMO Prize of the World Meteorological Organization for his pioneering work in numerical weather prediction - is by some margin the most distinguished scientist to change sides.

For most of his career, he has been a prominent member of the warmist establishment, subscribing to all its articles of faith - up to and including the belief that Michael Mann's Hockey Stick was a scientifically plausible assessment of the relationship between CO2 emissions and global mean temperature.

Living in the same country as Lennart Bengtsson comes from, how many words do you think have been written or said in main stream media here about this fact ? Zero. Not a single note or comment, what I´ve seen or heard. This in a country often being mentioned as one of the most democratic ones.....but is in reality only true if you have "politically correct" opinions. If not, you get frozen out and considered as a subject of ridicule. The swedish famous writer Wilhelm Moberg, put words on this already back in 1965 in an article in one of the bigger swedish newpapers and is how AGW is being considered here in a nutshell (my translation):
"In a democrature there are general and free elections, freedom of opinion formally applies but politics and media are dominated by an establishment that considers (only) certain opinions shall be put forward. The consequence is that the citizens are living with a vision that they are being given an objective and comprehensive picture of the reality. Repression of opinion is well covered, the free debate is being suffocated."

Same in Australia Anse with only a few journalists suggesting everything is not settled.

This is encouraging though, from Maurice Newman who chairs the Prime Minister’s Business Advisory Council:
Climate is right for a probe into the Bureau of Meteorology

WEATHER bureaus are a protected species. Often criticised, their workings remain a mystery to most of us. They continue to ­escape close scrutiny.

In an op-ed in Britain’s The Telegraph (December 19, 2010), the mayor of London, Boris Johnson, blamed much of the city’s pre-Christmas transport chaos on the Met Office. The Met had predicted 1C to 1.5C warmer temperatures. The reality was the coldest December in 100 years. “Is it really true no one saw this coming?” Johnson asked. Well no. He identified Piers Corbyn of Weather Action, a private weather forecaster, and went on: “He has no telescope or supercomputer. Using a laptop, huge quantities of publicly available data and a first-class degree in astrophysics, he gets it right, again and again.”

Perhaps a predisposition to man-made global warming accounts for the Met Office’s failure to predict abnormally harsh winters in Britain? After all, its chairman for two full terms was Robert Napier, a global warming activist and former head of WWF UK. The Met’s leaning came to light in leaked emails and revelations from Russian scientists. It and the Climatic Research Unit of the University of East Anglia were shown to have systematically contorted data past and present to achieve the desired warming dir­ection. The frustrated CRU climatologist-programmer, Ian “Harry” Harris, admitted to struggling with the complex computer programs and conceded he would do what the CRU usually did, “allow bad databases to pass ­unnoticed and good databases to become bad”.

The leaked emails also informed us of Australia’s collusion in the warming hype. There was an email from Phil Jones referring to Australia “inventing” the Dec­ember 1995 monthly value, and there was reference to Australian scientists who “would like to see the section on variability and extreme events beefed up if possible”. The head of climate monitoring and prediction ser­vices at the Bureau of Meteorology boasted about a policy that “snows” sceptics.

Doctoring data or throwing inquirers off the track to deliver an outcome is unscientific and unacceptable at any time. Yet in climate science there seems to be a culture of toleration. In 2009 John Theon, retired chief of NASA’s Climate Processes Research Program, testified to a US Senate inquiry that “scientists have manipulated the observed data to justify their model results”.

Fast forward to today. This newspaper’s environment editor, Graham Lloyd, published information that raises questions about the quality of Australia’s temperature records. In a series of articles, Lloyd published details about the Bureau of Meteorology’s data “homogenisation”, the practice that involves the mixing, matching and deletion of temperature records and that seemed to create its own discontinuities. The bureau claims to observe world best practice. Perhaps. But homogenisation practices globally are under challenge, so conformity provides little comfort. If temperature manipulation can happen somewhere, why not elsewhere?

In response to The Australian’s report, the BoM quietly released a “nothing to see here” summary of the impact of temperature adjustments at 112 locations around Australia with the list of reference stations used for comparison. The stated reasons for homogenisation seem arbitrary. Words like “merge”, “move” and “statistical”, provide little understanding of the thinking behind each decision or the reason stations were chosen. Colonial records are dismissed, notwithstanding the existence of Stevenson screens and the undoubted diligence of record keepers pre-1910. To the layman, the list of so-called “nearby” stations used to homogenise data raise questions of suitability. Is Bathurst jail really an appropriate site to include for homogenising Bourke’s records?

As a member of the World Meteorological Organisation, the BoM is inevitably caught up in global warming politics. After all it was the WMO that part established the Intergovernmental Panel on Climate Change and it remains an anthropogenic warming propagandist.

The BoM is a large and expensive agency, employing 1700 people and costing more than $300 million a year to run. The importance of its database and the reliability of its forecasts go well beyond direct operating costs and daily bulletins. As the bureau says, 10 per cent of Australia’s GDP is weather sensitive. This makes its input to public policy potentially valuable. But it must first dispel suspicions of a warming bias. The memory of Climategate and its casual approach to celsius conversion, lingers. It should explain why homogenisation consistently turns cooling trends to warming and why pre-1910 records were dropped and, with them, the extreme heatwaves of the Federation drought.

The record is error-ridden. Even to an amateur, the latest information dump prompts more questions than answers. The concerns about Rutherglen raised by Lloyd as to why a 0.35C cooling became a 1.73C warming still have no satisfactory explanation. No supporting documentary evidence, algorithms or methodology have been produced, leaving the unfortunate impression that temperature records were falsified.

As Einstein warned, “Whoever is careless with the truth in small matters cannot be trusted with important matters.” Indeed, those who doubted the reliability of the “high quality” records that were abandoned for the 2011 ACORN-Sat data are unlikely to find much comfort in the latest release. But it’s not only temperatures where doubts exist.

In 2008, David Stockwell, a niche ecological modelling expert, found: “The most worrying failure was that simulations (CSIRO/BoM models) showed increases in droughted area over the last century in all regions, while the observed trends in drought decreased in five of the seven regions identified.”

Lending its name to clearly partial scholarship only increases concerns that the bureau puts ­climate change advocacy ahead of scientific rigour and transparency. Trust in our national climate records is critical. Yet the more we see, the more we question. Now is not the time for a tame review.For the sake of public ­policy and the BoM’s reputation, the air must be cleared.

Nothing short of a thorough government-funded review and audit, conducted by independent professionals, will do.

Maurice Newman chairs the Prime Minister’s Business Advisory Council. These views are his own.

The article is behind a paywall but there is more from Mr Newman here:

No evidence that man has caused warming

He's sticking his neck out and - of course - has been roundly criticized.

I would have thought the new Prime Minister could call the head of BOM to a press present meeting and state something along the lines of the paragraph quoted above; then say: "I want a detailed explanation of the data from each and every weather station with actual observations and 'homogenized' values, and full justification if there is any difference for every station that is different. You will also produce a graph showing the actual recorded data as a time series then another showing the BOM modified values as a time series. I expect a fully documented explanation of any differences. You will produce that information next week at this time. The continued funding of BOM rests on a good presentation next week."

That might put a cat amongst the pigeons

We have plenty of pigeons but no cat .... yet. Courage is building, I hope.
