New Hockey Stick Sent to the Permanent Penalty Box

The “4,000-year hockey stick” scare is over, after a shelf life that did not last a full month. The warmist-fawning media used the 4,000-year hockey stick to create one of the most intense global warming scares in recent memory, but it quickly died with a thud – just like so many asserted global warming scares before it.

A little-known scientist who had only recently completed his Ph.D. published a paper claiming proxy temperature reconstructions showed a 4,000-year decline in global temperatures until the twentieth century. The paper claimed the 4,000-year decline abruptly ended in the twentieth century as recent warmth obliterated the 4,000 years of cooling and placed the Earth at its warmest in the 4,000-year record. Moreover, the asserted rapid temperature spike during the past century appeared to be the sharpest in 11,000 years. (more…)

Mann’s hockey stick disappears – and CRU’s Briffa helps make the MWP live again by pointing out bias in the data

by

Shock, awe. Untruncated and unspliced data used in a new paper from Briffa and Melvin at UEA restores the Medieval Warm Period while at the same time disappears Mann’s hockey stick. Here’s figure 5 that tells the story:

Figure 5. Temperature reconstructions created using the 650-tree (‘alltrw’ data) TRW chronology (a) and the 130 tree (‘S88G1112’ data) MXD chronology (b). Chronologies were created using two RCS curves and were regressed against the Bottenviken mean May–August monthly temperature over the period 1860 to 2006. The shaded areas show two standard errors (see SI15, available online, for details) plotted either side of the mean where standard errors were scaled to fit the temperature reconstruction. The TRW and MXD temperature reconstructions of (a) and (b) are compared in (c) after they were normalised over the common period 600 to 2008 and smoothed with a 10 year spline. The lower two panels compare the reconstructions using the TRW chronology (d) and MXD chronology (e) with the mean of May to August monthly temperature from Bottenviken over the period 1860 to 2006.

A man for all (climate) seasons?

Stephen McIntyre: total bloody hero.

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…)

The Tree Ring Circus

by John Dawson

The Hockey Stick Illusion is the shocking story of a graph called the Hockey Stick. It is also a textbook of tree ring analysis, a code-breaking adventure, an intriguing detective story, an exposé of a scientific and political travesty, and the tale of a herculean struggle between a self-funded sceptic and a publicly funded hydra, all presented in the measured style of an analytical treatise. The hero of the story is Steve McIntyre, honourably assisted by fellow sceptics, especially by Ross McKitrick. The villain is Michael Mann, dishonourably assisted by global warming alarmists, especially by his “Hockey Team”. The bare bones of the Hockey Stick story are as follows. (more…)

The case against the hockey stick

The “hockey stick” temperature graph is a mainstay of global warming science. A new book tells of one man’s efforts to dismantle it—and deserves to win prizes

Messy, truncated data? Trees on the Gaspé Peninsula in Canada: one of several pieces of evidence for rising temperatures that have been called into question


Andrew Montford’s The Hockey Stick Illusion is one of the best science books in years. It exposes in delicious detail, datum by datum, how a great scientific mistake of immense political weight was perpetrated, defended and camouflaged by a scientific establishment that should now be red with shame. It is a book about principal components, data mining and confidence intervals—subjects that have never before been made thrilling. It is the biography of a graph. (more…)

Climategate’s Phil Jones Confesses to Climate Fraud

Monday, February 15th, 2010

Source: American Thinker

By Marc Sheppard

By now, Phil Jones of the University of East Anglia’s Climatic Research Unit (CRU) should require no introduction, so let’s get right to it.  In a BBC Q&A and corresponding interview released Friday, the discredited Climategate conspirator revealed a number of surprising insights into his true climate beliefs, the most shocking of which was that 20th-century global warming may not have been unprecedented.  As the entire anthropogenic global warming (AGW) theory is predicated on correlation with rising CO2 levels, this first-such confession from an IPCC senior scientist is nothing short of earth-shattering.

Of course, much will be made of Jones’s claim that the refusal to share raw temperature data was partially based on the fact that it “was not well enough organized.” And rightly so, as the very idea that the major datasets CRU released for use in vital anomaly and temperature reconstructions were based on data not “organized” enough to be made public reeks of fraudulent behavior.

***********************

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…)

The global warming guerrillas

Matt Ridley salutes the bloggers who changed the climate debate. While most of Fleet Street kowtowed to the green lobby, online amateurs uncovered the spin and deception that finally cracked the consensus

Journalists are wont to moan that the slow death of newspapers will mean a disastrous loss of investigative reporting. The web is all very well, they say, but who will pay for the tenacious sniffing newshounds to flush out the real story? ‘Climategate’ proves the opposite to be true. It was amateur bloggers who scented the exaggerations, distortions and corruptions in the climate establishment; whereas newspaper reporters, even after the scandal broke, played poodle to their sources.
