Two New GW Statements Out This Week

Posted By Dave Snope

Choose yer favrit!

Here Is Statement #1:
...climate change injects a major new source of chaos, tension, and human insecurity into an already volatile world. It threatens to bring more famine and drought, worse pandemics, more natural disasters, more resource scarcity, and human displacement on a staggering scale. Places only too familiar with the instability, conflict, and resource competition that often create refugees and IDPs, will now confront these same challenges with an ever growing population of EDPs—environmentally displaced people. We risk fanning the flames of failed-statism, and offering glaring opportunities to the worst actors in our international system. In an interconnected world, that endangers all of us... Nowhere is the nexus between today’s threats and climate change more acute than in South Asia–the home of Al Qaeda and the center of our terrorist threat. ... climate change risks making the most volatile places even more combustible... If we fail to connect the dots—if we fail to take action—the simple, indisputable reality is that we will find ourselves living not only in a ravaged environment, but also in a much more dangerous world...

Sen. John Kerry, 21 July 2009. Chair of the Senate Foreign Relations Committee, Opening Remarks on the Committee's new top priority.

Statement #2:

“The surge in global temperatures since 1977 can be attributed to a 1976 climate shift in the Pacific Ocean that made warming El Niño conditions more likely than they were over the previous 30 years and cooling La Niña conditions less likely” ... “When climate models failed to retrospectively produce the temperatures since 1950 the modellers added some estimated influences of carbon dioxide to make up the shortfall,”... “The close relationship between ENSO and global temperature, as described in the paper, leaves little room for any warming driven by human carbon dioxide emissions. The available data indicate that future global temperatures will continue to change primarily in response to ENSO cycling, volcanic activity and solar changes.” ... “Our paper confirms what many scientists already know: which is that no scientific justification exists for emissions regulation, and that, irrespective of the severity of the cuts proposed, ETS (emission trading scheme) will exert no measurable effect on future climate.”

Perpectives From UN Climate Change Meeting

Posted By Dave Snope

First, from a skeptic president:
Czech President Vaclav Klaus sharply criticized a U.N. meeting on climate change on Tuesday at which U.S. President Barack Obama was among the top speakers, describing it as propagandistic and undignified.

"It was sad and it was frustrating," said Klaus, one of the world's most vocal skeptics on the topic of global warming.

"It's a propagandistic exercise where 13-year-old girls from some far-away country perform a pre-rehearsed poem," he said. "It's simply not dignified."

At the opening of the summit attended by nearly 100 world leaders, 13-year-old Yugratna Srivastava of India told the audience that governments were not doing enough to combat the threat of climate change.

Klaus said there were increasing doubts in the scientific community about whether humans are causing changes in the climate or whether the changes are simply naturally occurring phenomena.

But politicians, he said, seem to be moving closer to a consensus on climate change.

Second, from a believing ex-president and Obama supporter:

HAVANA — Barack Obama's call for action on climate change and his admission that rich nations have a particular responsibility to lead has received strong praise from an unusual source — U.S. nemesis Fidel Castro.

The former Cuban leader on Wednesday called the American president's speech at the United Nations "brave" and said no other American head of state would have had the courage to make similar remarks.

Melting Ice Caps Expose Hundreds Of Arctic Lairs

Posted By Dave Snope

ZACKENBERG RESEARCH STATION, GREENLAND—Claiming it to be one of the most dramatic and visible signs of climate change to date, researchers said Monday that receding polar ice caps have revealed nearly 200 clandestine lairs once buried deep beneath hundreds of feet of Arctic ice.

"We always assumed there would be some secret lairs here and there, but the sheer number now being exposed is indeed troubling," said noted climatologist Anders Lorenzen, who claimed that the Arctic ice caps have shrunk at the alarming rate of 41,000 square miles per year. "In August alone we discovered 44 mad scientist laboratories, three highly classified military compounds, and seven reanimated and very confused cavemen. That's more than twice the number we had found in the previous three decades combined."

"This is no longer conjecture," Lorenzen added. "This is a full-blown crisis."

According to oceanographers, the Arctic Circle has been devastated by the effects of global warming in recent years, threatening hundreds of men and women who use the frozen tundra as a place to conduct bizarre experiments in human-animal grafting, carry out massive government cover-ups, or simply as a hidden headquarters from which to battle the forces of evil and fight crime.

Antarctic Sea Ice Holds Well Above Average

Posted By Dave Snope

Good news, if you like ice in the south. The Antarctic sea ice extent continued it's climb in late September and is now 1 million square miles greater than the 1979-2000 average.

Another AGW Scientist Disgraced

Posted By Dave Snope

It's getting hard to find an honest research paper in AGW science. Data-hiding, cherry-picking, data-swapping, data-fabrication, and cover-ups seem to be the norm in peer-reviewed scientific journal publications on AGW. Then the bad data, authenticated via publication, is re-used by others in new peer-reviewed publications and eventually makes it into the IPCC. Jones, Mann, Hansen, Wang, Britta, Schweingruber, the heavy hitters in climate history are all doin' it. Apparently it's hip to pick. If it weren't for the Freedom of Information Act, and data sharing rules at Royal Society, they would still be getting away with it. They are the Deniers, fighting tooth and and nail to deny their climate data to scientific inquiry.

Thanks to Steve McIntyre's persistence in getting original data, we can now see what happens when you use the full set of tree ring data instead of just the 5 or 10 selected trees from selected sources used in the CRU. See black line in graph. Green line is merged data sets. The 20th century is no longer the warmest century.

A chronological summary by Ross McKitrick:
Here's a re-cap of this saga that should make clear the stunning importance of what Steve has found. One point of terminology: a tree ring record from a site is called a chronology, and is made up of tree ring records from individual trees at that site. Multiple tree ring series are combined using standard statistical algorithms that involve detrending and averaging (these methods are not at issue in this thread). A good chronology–good enough for research that is–should have at least 10 trees in it, and typically has much more.

1. In a 1995 Nature paper by Briffa, Schweingruber et al., they reported that 1032 was the coldest year of the millennium - right in the middle of the Medieval Warm Period. But the reconstruction depended on 3 short tree ring cores from the Polar Urals whose dating was very problematic.

2. In the 1990s, Schweingruber obtained new Polar Urals data with more securely-dated cores for the MWP. Neither Briffa nor Schweingruber published a new Polar Urals chronology using this data. An updated chronology with this data would have yielded a very different picture, namely a warm medieval era and no anomalous 20th century. Rather than using the updated Polar Urals series, Briffa calculated a new chronology from Yamal - one which had an enormous hockey stick shape. After its publication, in virtually every study, Hockey Team members dropped Polar Urals altogether and substituted Briffa's Yamal series in its place. PS: The exception to this pattern was Esper et al (Science) 2002, which used the combined Polar Urals data. But Esper refused to provide his data. Steve got it in 2006 after extensive quasi-litigation with Science (over 30 email requests and demands).

3. Subsequently, countless studies appeared from the Team that not only used the Yamal data in place of the Polar Urals, but where Yamal had a critical impact on the relative ranking of the 20th century versus the medieval era.

4. Meanwhile Briffa repeatedly refused to release the Yamal measurement data used inhis calculation despite multiple uses of this series at journals that claimed to require data archiving. E.g.

5. Then one day Briffa et al. published a paper in 2008 using the Yamal series, again without archiving it. However they published in a Phil Tran Royal Soc journal which has strict data sharing rules. Steve got on the case.

6. A short time ago, with the help of the journal editors, the data was pried loose and appeared at the CRU web site.

7. It turns out that the late 20th century in the Yamal series has only 10 tree ring chronologies after 1990 (5 after 1995), making it too thin a sample to use (according to conventional rules). But the real problem wasn't that there were only 5-10 late 20th century cores- there must have been a lot more. They were only using a subset of 10 cores as of 1990, but there was no reason to use a small subset. (Had these been randomly selected, this would be a thin sample, but perhaps passable. But it appears that they weren't randomly selected.)

8. Faced with a sample in the Taymir chronology that likely had 3-4 times as many series as the Yamal chronology, Briffa added in data from other researchers' samples taken at the Avam site, some 400 km away. He also used data from the Schweingruber sampling program circa 1990, also taken about 400 km from Taymir. Regardless of the merits or otherwise of pooling samples from such disparate locations, this establishes a precedent where Briffa added a Schweingruber site to provide additional samples. This, incidentally, ramped up the hockey-stickness of the (now Avam-) Taymir chronology.

9. Steve thus looked for data from other samples at or near the Yamal site that could have been used to increase the sample size in the Briffa Yamal chronology. He quickly discovered a large set of 34 Schweingruber samples from living trees. Using these instead of the 12 trees in the Briffa (CRU) group that extend to the present yields Figure 2, showing a complete divergence in the 20th century. Thus the Schweingruber data completely contradicts the CRU series. Bear in mind the close collaboration of Schweingruber and Briffa all this time, and their habit of using one another's data as needed.

10. Combining the CRU and Schweingruber data yields the green line in the 3rd figure above. While it doesn't go down at the end, neither does it go up, and it yields a medieval era warmer than the present, on the standard interpretation. Thus the key ingredient in a lot of the studies that have been invoked to support the Hockey Stick, namely the Briffa Yamal series (red line above) depends on the influence of a thin subsample of post-1990 chronologies and the exclusion of the (much larger) collection of readily-available Schweingruber data for the same area.

New Yamal 2000 Year Tree Ring Plots

Posted By Dave Snope

Now that the Yamal data is made available this week (this is the data that was used to generate Briffa's hockey stick curve and hidden for 10 years), McIntyre and Watt have been busy plotting it. All of it, rather than the hand-selected few trees that yield a hockey stick and lead to all the scary science reported at BBC and NYT and IPCC.

They've been busy checking and re-checking, plotting and replotting, and having others plot and check their work because the data is so flat.

Here's all 2000 years of all the trees:

Here is the last 200 years:

Anthony included to original authors (Hantemirov & Shiyatov) plots too. It shows the same thing.

IPPC Review Member Comments on Process

Posted By Dave Snope

I have been probing the arguments for global warming for well over a decade. In collaboration with a lot of excellent coauthors I have consistently found that when the layers get peeled back, what lies at the core is either flawed, misleading or simply non-existent. The surface temperature data is a contaminated mess with a significant warm bias, and as I have detailed elsewhere the IPCC fabricated evidence in its 2007 report to cover up the problem. Climate models are in gross disagreement with observations, and the discrepancy is growing with each passing year. The often-hyped claim that the modern climate has departed from natural variability depended on flawed statistical methods and low-quality data. The IPCC review process, of which I was a member last time, is nothing at all like what the public has been told: Conflicts of interest are endemic, critical evidence is systematically ignored and there are no effective checks and balances against bias or distortion.

I get exasperated with fellow academics, and others who ought to know better, who pile on to the supposed global warming consensus without bothering to investigate any of the glaring scientific discrepancies and procedural flaws. Over the coming few years, as the costs of global warming policies mount and the evidence of a crisis continues to collapse, perhaps it will become socially permissible for people to start thinking for themselves again. In the meantime I am grateful for those few independent thinkers, like Steve McIntyre, who continue to ask the right questions and insist on scientific standards of openness and transparency. - Ross McKitrick

Flawed Yamal Data in Nature, Science, and IPCC

Posted By Dave Snope

Over the next nine years, at least one paper per year appeared in prominent journals using Briffa's Yamal composite to support a hockey stick-like result. The IPCC relied on these studies to defend the Hockey Stick view, and since it had appointed Briffa himself to be the IPCC Lead Author for this topic, there was no chance it would question the Yamal data.

Despite the fact that these papers appeared in top journals like Nature and Science, none of the journal reviewers or editors ever required Briffa to release his Yamal data. Steve McIntyre's repeated requests for them to uphold their own data disclosure rules were ignored.
