Sir,

Charles Battig did a great service to your readers by spreading truth about the now-collapsed climate scare. Michael Mann’s criticisms of him (August 5) were ill-founded. Attorney General Cuccinelli investigated Mr Mann under the Fraud Against Taxpayers Act 2000 because of what I shall delicately call the statistical peculiarities evident in Mr Mann’s “hockey stick” graph that had purported to abolish the medieval warm period and to show – falsely – that today’s quite normal global temperatures were unprecedented in 1300 years.

Mr Mann’s graph relied heavily upon the widths of tree-rings from bristlecone pines as a basis for estimating temperatures before we had thermometers, although these pines are unreliable proxies because the tree-rings widen not only when the weather is warmer but also when it is wetter and when there is more CO2 in the air. That kinda musses things up. (more…)

Climate Science: Opinions, Baloney And Bloggers

Our world is based upon science. It is a shame, though perhaps inevitable, that more people do not truly appreciate it. The clothes you wear, the mobile phone you use, the food you eat and the vaccination that protects your child are all wonders of science, based on so many generations of scientists carrying out observations and measurements, formulating hypotheses and theories, using logic and mathematical models.

Few would argue that climate science has not been controversial, even if opinions as to why differ. It is important to everyone on the planet, so the bar on evidence and conclusions should be set high. But climate science is no different from any other area of science. The process of science involves scrutiny, questioning and often cussed unreasonableness in the face of data, its gathering and interpretation. Truth will out eventually and the result is progress, a step towards better understanding. Carl Sagan (how he is missed) once told me that science was a “baloney detection kit.” (more…)

Tree-rings prove climate was WARMER in Roman and Medieval times

Wednesday, July 11th, 2012

  • Tree ring study gives first accurate climate reading back to 138BC
  • World has been slowly cooling for 2,000 years
  • World was warmer in Roman and Medieval times than it is now
  • Study of semi-fossilised trees in Finland
Rings in fossilised pine trees have proven that the world was much warmer than previously thought – and the earth has been slowly COOLING for 2,000 years.

Measurements stretching back to 138BC prove that the Earth is slowly cooling due to changes in the distance between the Earth and the sun.

The finding may force scientists to rethink current theories of the impact of global warming.

It is the first time that researchers have been able to accurately measure trends in global temperature over the last two millennia. (more…)

A Real Hockey Stick Graph

Yes, we have no bananas

From The Viscount Monckton of Brenchley

Cancun, Mexico

I dined with Dr. Roy Spencer as the Atlantic rollers swished and crashed against the long, sandy beach here in Cancun. We ate coconut-crusted camarones. Appropriately, shrimps in the Spanish-speaking world are named after the British Prime Minister, the truest of true believers in the New-Age religion that is the Church of “Global Warming”.

Cameron, or “Dave”, as he matily likes to be known, had been careful not to reveal his blind faith in the febrile fatuities of the forecasters of fashionable fatalism to his followers in Not The Conservative Party before they picked him as their leader: but, in his very first speech as Supreme Shrimp, he made it plain to the fawning news media that Saving The Planet would be his very firstest priority, yes indeedy.

Stephen McIntyre: total bloody hero.

Steve McIntyre has been named one of the 50 People Who Matter by the left-wing journal New Statesman. He comes in at number 32. (Below a motley crew including Osama Bin Laden, Hugo Chavez, David Cameron, Julian Assange, Barack Obama, and the like). (H/T Roddy Campbell)

Here’s what his entry says:

When the mining expert Stephen McIntyre challenged the basis of climate science on his blog, he became a figurehead for many climate-change sceptics.

His subsequent involvement in the 2009 “Climategate” controversy at the University of East Anglia (he was referred to in the hacked emails over 100 times) emboldened the sceptics further and changed global opinion: the number of people who believe man is responsible for global warming has fallen.

The influence might not be positive, but there’s no doubt he has shaped the debate. (more…)

I receive many e-mails, and a recurring complaint is that many of my posts are too technical to understand. This morning’s installment arrived with the subject line, “Please Talk to Us”, and suggested I provide short, concise, easily understood summaries and explanations “for dummies”.

So, here’s a list of basic climate change questions, and brief answers based upon what I know today. I might update them as I receive suggestions and comments. I will also be adding links to other sources, and some visual aids, as appropriate. (more…)

The main statistical error found with the “hockey stick” graph of temperatures

Friday, April 23rd, 2010

by Douglas Keenan

Following is a simplified description of the main statistical error found with the “hockey stick” graph of temperatures during the past millennium.

Michael Mann, Raymond Bradley, and Malcolm Hughes are three respected scientists in America. In 1998 and 1999, they jointly published some research on how temperatures have changed during the past millennium. According to their research, the temperature in the Northern Hemisphere was roughly constant during the millennium, up until the twentieth century; then, in the twentieth century, temperatures increased very substantially. Their graph of hemispheric temperatures is shown below.

Hockey Stick graph

The graph was dubbed the “hockey stick”, because of its shape. It became an icon for many people concerned about global warming, and it was prominently featured in the 2001 report from the Intergovernmental Panel on Climate Change. (more…)

There He Goes Again: Mann Claims His Hockey Stick was Given “Clean Bill of Health”

Monday, April 19th, 2010

Spinmeister Michael Mann is quoted in this article from the Telegraph yesterday as follows:

Prof Hand (Head of the UK Royal Statistical Society) praised the blogger Steve McIntyre of Climate Audit for uncovering the fact that inappropriate methods were used which could produce misleading results. ”The Mann 1998 hockey stick paper used a particular technique that exaggerated the hockey stick effect,” he said.

Prof Mann, who is Professor of Earth System Science at the Pennsylvania State University, said the statistics used in his graph were correct. ”I would note that our ’98 article was reviewed by the US National Academy of Sciences, the highest scientific authority in the United States, and given a clean bill of health,” he said. “In fact, the statistician on the panel, Peter Bloomfield, a member of the Royal Statistical Society, came to the opposite conclusion of Prof Hand.” (more…)

The Heretics: McIntyre and McKitrick

When the infamous hockey-stick graph that purported to prove that human activities are causing runaway global warming was finally broken, there is some irony in the fact that a couple of Canadians did the breaking. Retired mining engineer Steve McIntyre and Ross McKitrick, Professor of Economics at the University of Guelph, have been a thorn in the side of global warming alarmists for years. McIntyre, McKitrick and, more often, the acronym “M&M” to refer to the pair, are the subject of many discussions in the e-mails released from the University of East Anglia’s Climate Research Unit (CRU) last November.

Review #1 — The “Bishop Hill” blog was well-respected, but not particularly remarkable until the posting of “Caspar and the Jesus paper” in August 2008. With this posting, we learned that the esteemed Bishop (now also revealed as Andrew Montford), the author of this new book, had a talent for putting scattered bits and pieces of information into a highly coherent presentation. It was remarkable enough that he was able to take myriad blog postings and figure out what they all added up to, and further remarkable that he was able to map this understanding into writing. Would it be possible to achieve this Casper-style in a more encompassing work? Too much to ask for? Well, HERE it is! (more…)

How Met Office blocked questions on its own man’s role in ‘hockey stick’ climate row

Sunday, February 7th, 2010

Source: Mail Online

By David Rose

The Meteorological Office is blocking public scrutiny of the central role played by its top climate scientist in a highly controversial report by the beleaguered United Nations Intergovernmental Panel on Climate Change.

Professor John Mitchell, the Met Office’s Director of Climate Science, shared responsibility for the most worrying headline in the 2007 Nobel Prize-winning IPCC report – that the Earth is now hotter than at any time in the past 1,300 years.

And he approved the inclusion in the report of the famous ‘hockey stick’ graph, showing centuries of level or declining temperatures until a steep 20th Century rise. (more…)

The end is not near

By Dr Fred Singer, Hindustan Times

The Intergovernmental Panel on Climate Change (IPCC) has acknowledged they made a mistake in their projection of 2035 as the year when Himalayan glaciers were said to melt. But the blunder is not a one-off mistake, and is the latest in the litany of errors that have dogged the panel over the past ten years.

In their 2001 report, they claimed that the 20th century was “unusual” and blamed it on human-released greenhouse gases. Their infamous temperature graph shown there, shaped like a hockey stick, did away with the well-established Medieval Warm Period (around 1000A.D.) and the following Little Ice Age (around 1400 to 1800A.D.). Two Canadians exposed the bad data used by the panel and the statistical errors in their analysis. In mid-August, after repeated requests for such data under the Freedom of Information Act, the Climate Research Unit at the University of East Anglia (CRU), one of the three international agencies that calculate global temperatures, announced that it discarded the raw data used to calculate global surface temperatures. This action renders independent review and verification of the temperature trends published by it impossible – a clear violation of principles of science and the Act. (more…)

Controversy behind climate science’s ‘hockey stick’ graph

Wednesday, February 3rd, 2010

Hockey stick graph The pioneering ‘hockey stick’ graph collected proxy temperature data from tree rings, lake sediments and ice cores It is a persuasive image. The “hockey stick” graph shows the average global temperature over the past 1,000 years. For the first 900 years there is little variation, like the shaft of an ice-hockey stick. Then, in the 20th century, comes a sharp rise like the stick’s blade.The graph was a pioneering attempt to put together data from hundreds of studies of past temperature using “proxies” from analysing things like tree rings, lake sediments and ice cores. The resulting shape, first published by Professor Mike Mann of Pennsylvania State University in 1998, has become a symbol of the conflict between mainstream climate scientists and their critics. The deniers say it is a lie. Climate scientist stand by it. (more…)

Amazongate: new evidence of the IPCC’s failures

Monday, February 1st, 2010

by Christopher Booker

The claim in an IPCC report that 40 per cent of the Amazon rainforest could disappear through global warming turned out to be unfounded.

It is now six weeks since I launched an investigation, with my colleague Richard North, into the affairs of Dr Rajendra Pachauri, chairman of the UN’s Intergovernmental Panel on Climate Change (IPCC), the hugely influential body which for 20 years has been the central driver of worldwide alarm about global warming. Since then the story has grown almost daily, leading to worldwide calls for Dr Pachauri’s resignation. But increasingly this has also widened out to question the authority of the IPCC itself. Contrary to the tendentious claim that its reports represent a “consensus of the world’s top 2,500 climate scientists” (most of its contributors are not climate experts at all), it has now emerged, for instance, that one of the more widely quoted scare stories from its 2007 report was drawn from the work of a British “green activist” who occasionally writes as a freelance for The Guardian and The Independent.
