Climategate U-turn
caseyresearch.com
Here are a couple things that should really stick in Al Gore’s craw (where did that expression come from anyway?).
This story out of the UK’s Daily Mail indicates that the academic at the center of the “Climategate” affair has now conceded the possibility that global warming may not be a man-made phenomenon and that for the past 15 years, there has been no “statistically significant” warming.

To quote the article:
The academic at the centre of the ‘Climategate’ affair, whose raw data is crucial to the theory of climate change, has admitted that he has trouble ‘keeping track’ of the information.
Colleagues say that the reason Professor Phil Jones has refused Freedom of Information requests is that he may have actually lost the relevant papers.
Professor Jones told the BBC yesterday there was truth in the observations of colleagues that he lacked organizational skills, that his office was swamped with piles of paper and that his record keeping is ‘not as good as it should be.’
The data is crucial to the famous ‘hockey stick graph’ used by climate change advocates to support the theory.
Professor Jones also conceded the possibility that the world was warmer in medieval times than now – suggesting global warming may not be a man-made phenomenon.
And he said that for the past 15 years there has been no ‘statstistically significant’ warming.
And then there’s this story from The Times, which suggests the world may not be warming at all.

Here’s an excerpt:
The United Nations climate panel faces a new challenge with scientists casting doubt on its claim that global temperatures are rising inexorably because of human pollution.
In its last assessment the Intergovernmental Panel on Climate Change (IPCC) said the evidence that the world was warming was “unequivocal”.
It warned that greenhouse gases had already heated the world by 0.7°C and that there could be 5°C-6°C more warming by 2100, with devastating impacts on humanity and wildlife. However, new research, including work by British scientists, is casting doubt on such claims. Some even suggest the world may not be warming much at all.
“The temperature records cannot be relied on as indicators of global change,” said John Christy, professor of atmospheric science at the University of Alabama in Huntsville, a former lead author on the IPCC.
The doubts of Christy and a number of other researchers focus on the thousands of weather stations around the world, which have been used to collect temperature data over the past 150 years.
These stations, they believe, have been seriously compromised by factors such as urbanisation, changes in land use and, in many cases, being moved from site to site.
Christy has published research papers looking at these effects in three different regions: east Africa, and the American states of California and Alabama.
“The story is the same for each one,” he said. “The popular data sets show a lot of warming but the apparent temperature rise was actually caused by local factors affecting the weather stations, such as land development.”
The IPCC faces similar criticisms from Ross McKitrick, professor of economics at the University of Guelph, Canada, who was invited by the panel to review its last report.
The experience turned him into a strong critic and he has since published a research paper questioning its methods.
“We concluded, with overwhelming statistical significance, that the IPCC’s climate data are contaminated with surface effects from industrialisation and data quality problems. These add up to a large warming bias,” he said.
Such warnings are supported by a study of US weather stations co-written by Anthony Watts, an American meteorologist and climate change sceptic…
… Terry Mills, professor of applied statistics and econometrics at Loughborough University, looked at the same data as the IPCC. He found that the warming trend it reported over the past 30 years or so was just as likely to be due to random fluctuations as to the impacts of greenhouse gases. Mills’s findings are to be published in Climatic Change, an environmental journal.
“The earth has gone through warming spells like these at least twice before in the last 1,000 years,” he said.
Why do we so often hit on this topic in this missive? Because it’s important for you and for your investments that you know the truth. Anthropogenic global warming is by no means a done deal in the science world as President Obama and the power elite in Washington so often claim. And any legislation that comes about (in the U.S. or elsewhere) touting that it’s being done to “save the planet” needs to be recognized for what it is – just another attempt by the powers-that-be to benefit certain special interests at the expense of everybody else.

Data for vital 'hockey stick graph' has gone missing
There has been no global warming since 1995
Warming periods have happened before - but NOT due to man-made changes
Data: Professor Phil Jones admitted his record keeping is 'not as good as it should be'
The academic at the centre of the ‘Climategate’ affair, whose raw data is crucial to the theory of climate change, has admitted that he has trouble ‘keeping track’ of the information.
Colleagues say that the reason Professor Phil Jones has refused Freedom of Information requests is that he may have actually lost the relevant papers.
Professor Jones told the BBC yesterday there was truth in the observations of colleagues that he lacked organisational skills, that his office was swamped with piles of paper and that his record keeping is ‘not as good as it should be’.
The data is crucial to the famous ‘hockey stick graph’ used by climate change advocates to support the theory.
Professor Jones also conceded the possibility that the world was warmer in medieval times than now – suggesting global warming may not be a man-made phenomenon.
And he said that for the past 15 years there has been no ‘statistically significant’ warming.
The admissions will be seized on by sceptics as fresh evidence that there are serious flaws at the heart of the science of climate change and the orthodoxy that recent rises in temperature are largely man-made.
Professor Jones has been in the spotlight since he stepped down as director of the University of East Anglia’s Climatic Research Unit after the leaking of emails that sceptics claim show scientists were manipulating data.
The raw data, collected from hundreds of weather stations around the world and analysed by his unit, has been used for years to bolster efforts by the United Nation’s Intergovernmental Panel on Climate Change to press governments to cut carbon dioxide emissions.
Following the leak of the emails, Professor Jones has been accused of ‘scientific fraud’ for allegedly deliberately suppressing information and refusing to share vital data with critics.
Discussing the interview, the BBC’s environmental analyst Roger Harrabin said he had spoken to colleagues of Professor Jones who had told him that his strengths included integrity and doggedness but not record-keeping and office tidying.
Mr Harrabin, who conducted the interview for the BBC’s website, said the professor had been collating tens of thousands of pieces of data from around the world to produce a coherent record of temperature change.
That material has been used to produce the ‘hockey stick graph’ which is relatively flat for centuries before rising steeply in recent decades.
According to Mr Harrabin, colleagues of Professor Jones said ‘his office is piled high with paper, fragments from over the years, tens of thousands of pieces of paper, and they suspect what happened was he took in the raw data to a central database and then let the pieces of paper go because he never realised that 20 years later he would be held to account over them’.
Asked by Mr Harrabin about these issues, Professor Jones admitted the lack of organisation in the system had contributed to his reluctance to share data with critics, which he regretted.
But he denied he had cheated over the data or unfairly influenced the scientific process, and said he still believed recent temperature rises were predominantly man-made.
Asked about whether he lost track of data, Professor Jones said: ‘There is some truth in that. We do have a trail of where the weather stations have come from but it’s probably not as good as it should be.
‘There’s a continual updating of the dataset. Keeping track of everything is difficult. Some countries will do lots of checking on their data then issue improved data, so it can be very difficult. We have improved but we have to improve more.’
He also agreed that there had been two periods which experienced similar warming, from 1910 to 1940 and from 1975 to 1998, but said these could be explained by natural phenomena whereas more recent warming could not.
He further admitted that in the last 15 years there had been no ‘statistically significant’ warming, although he argued this was a blip rather than the long-term trend.
And he said that the debate over whether the world could have been even warmer than now during the medieval period, when there is evidence of high temperatures in northern countries, was far from settled.
Sceptics believe there is strong evidence that the world was warmer between about 800 and 1300 AD than now because of evidence of high temperatures in northern countries.
But climate change advocates have dismissed this as false or only applying to the northern part of the world.
Professor Jones departed from this consensus when he said: ‘There is much debate over whether the Medieval Warm Period was global in extent or not. The MWP is most clearly expressed in parts of North America, the North Atlantic and Europe and parts of Asia.
‘For it to be global in extent, the MWP would need to be seen clearly in more records from the tropical regions and the Southern hemisphere. There are very few palaeoclimatic records for these latter two regions.
‘Of course, if the MWP was shown to be global in extent and as warm or warmer than today, then obviously the late 20th Century warmth would not be unprecedented. On the other hand, if the MWP was global, but was less warm than today, then the current warmth would be unprecedented.’
Sceptics said this was the first time a senior scientist working with the IPCC had admitted to the possibility that the Medieval Warming Period could have been global, and therefore the world could have been hotter then than now.
Professor Jones criticised those who complained he had not shared his data with them, saying they could always collate their own from publicly available material in the US. And he said the climate had not cooled ‘until recently – and then barely at all. The trend is a warming trend’.
Mr Harrabin told Radio 4’s Today programme that, despite the controversies, there still appeared to be no fundamental flaws in the majority scientific view that climate change was largely man-made.
But Dr Benny Pieser, director of the sceptical Global Warming Policy Foundation, said Professor Jones’s ‘excuses’ for his failure to share data were hollow as he had shared it with colleagues and ‘mates’.
He said that until all the data was released, sceptics could not test it to see if it supported the conclusions claimed by climate change advocates.
He added that the professor’s concessions over medieval warming were ‘significant’ because they were his first public admission that the science was not settled.

World may not be warming, say scientists
Jonathan Leake The United Nations climate panel faces a new challenge with scientists casting doubt on its claim that global temperatures are rising inexorably because of human pollution.

In its last assessment the Intergovernmental Panel on Climate Change (IPCC) said the evidence that the world was warming was “unequivocal”.
It warned that greenhouse gases had already heated the world by 0.7C and that there could be 5C-6C more warming by 2100, with devastating impacts on humanity and wildlife. However, new research, including work by British scientists, is casting doubt on such claims. Some even suggest the world may not be warming much at all.
“The temperature records cannot be relied on as indicators of global change,” said John Christy, professor of atmospheric science at the University of Alabama in Huntsville, a former lead author on the IPCC.
The doubts of Christy and a number of other researchers focus on the thousands of weather stations around the world, which have been used to collect temperature data over the past 150 years.
These stations, they believe, have been seriously compromised by factors such as urbanisation, changes in land use and, in many cases, being moved from site to site.
Christy has published research papers looking at these effects in three different regions: east Africa, and the American states of California and Alabama.
“The story is the same for each one,” he said. “The popular data sets show a lot of warming but the apparent temperature rise was actually caused by local factors affecting the weather stations, such as land development.”
The IPCC faces similar criticisms from Ross McKitrick, professor of economics at the University of Guelph, Canada, who was invited by the panel to review its last report.
The experience turned him into a strong critic and he has since published a research paper questioning its methods.
“We concluded, with overwhelming statistical significance, that the IPCC’s climate data are contaminated with surface effects from industrialisation and data quality problems. These add up to a large warming bias,” he said.
Such warnings are supported by a study of US weather stations co-written by Anthony Watts, an American meteorologist and climate change sceptic.
His study, which has not been peer reviewed, is illustrated with photographs of weather stations in locations where their readings are distorted by heat-generating equipment.
Some are next to air- conditioning units or are on waste treatment plants. One of the most infamous shows a weather station next to a waste incinerator.
Watts has also found examples overseas, such as the weather station at Rome airport, which catches the hot exhaust fumes emitted by taxiing jets.
In Britain, a weather station at Manchester airport was built when the surrounding land was mainly fields but is now surrounded by heat-generating buildings.
Terry Mills, professor of applied statistics and econometrics at Loughborough University, looked at the same data as the IPCC. He found that the warming trend it reported over the past 30 years or so was just as likely to be due to random fluctuations as to the impacts of greenhouse gases. Mills’s findings are to be published in Climatic Change, an environmental journal.
“The earth has gone through warming spells like these at least twice before in the last 1,000 years,” he said.
Kevin Trenberth, a lead author of the chapter of the IPCC report that deals with the observed temperature changes, said he accepted there were problems with the global thermometer record but these had been accounted for in the final report.
“It’s not just temperature rises that tell us the world is warming,” he said. “We also have physical changes like the fact that sea levels have risen around five inches since 1972, the Arctic icecap has declined by 40% and snow cover in the northern hemisphere has declined.”
The European Centre for Medium-Range Weather Forecasts has recently issued a new set of global temperature readings covering the past 30 years, with thermometer readings augmented by satellite data.
Dr Vicky Pope, head of climate change advice at the Met Office, said: “This new set of data confirms the trend towards rising global temperatures and suggest that, if anything, the world is warming even more quickly than we had thought.” |
