The Washington Post is touting a new study purporting to show an Arctic temperature “Hockey Stick.” But the study appears to contradict numerous previous Arctic studies and scientists are already challenging the premise and claims of the new study. The study in under fire for basing key results and conclusions on Penn State Professor Michael Mann’s discredited “Hockey Stick” temperature graph. (Editor’s Note: Mann just recently attempted to invent a hurricane “Hockey Stick” as well. )
The new study claims to show “human-generated greenhouse gas emissions have helped reverse a 2,000-year trend of cooling in the Arctic, prompting warmer average temperatures in the past decade that now rank higher than at any time since 1 B.C.,” according to a September 3, 2009 article by the Washington Post’s Juliet Eilperin. The study will appear in the September 3, 2009 online version of the journal Science. The lead author was Northern Arizona University professor Darrell S. Kaufman.
The Washington Post also saw fit to gave prominent play to the environmental group World Wildlife Fund’s new dire Arctic study claiming a scary global warming caused “transformation” of the Arctic. (The study is getting the alarmist media promote. See: USA Today: ‘Arctic temperatures hit 2,000-year high’ – But Andrew Revkin of NYT has much more balanced coverage of the study.) The Post article on the new Arctic “Hockey Stick” completely glossed over years of contrary data and instead mostly gave the authors a scrutiny free ride. (Eilperin also misspelled the name of one scientist she quoted.)
MIT climate scientist Dr. Richard Lindzen told Climate Depot, “This looks like this week’s “Hockey Stick” including many of Mann’s collaborators.” [Editor's Note: Mann's has attempted multiple "Hockey Stick" inventions and his newest creation is the Hurricane "Hockey Stick.”.]
‘Closely matches the Mann version’
Climate data analyst Steve McIntyre who publishes Climate Audit and is known for his research discrediting Mann’s original “Hockey Stick” temperature graph, weighed in on the new Arctic study. “Amusingly, the [Arctic study's lead author] Kaufman Team perpetuates Mann’s upside down use of the Tiljander proxy,” McIntyre wrote on September 3, 2009. “You can readily see that this closely matches the Mann version,” McIntyre noted. “The most cursory examination [of the study] shows the usual problem of seemingly biased picking of proxies without any attempt to reconcile proxy conflicts,” McIntryre wrote.
‘Several things wrong’
Atmospheric Scientist Dr. Fred Singer, former director of the U.S. Weather Satellite Service, also critiqued the study, telling Climate Depot, “There are several things wrong with this paper.”
“The study’s Abstract mentions the [warm] ‘Middle Ages’ and the [cold] ‘Little Ice Age.’ Both are well established; for example, C. Loehle (and many other researchers) show the Medieval Warm Period with higher temperatures than even the past 30 years. But Fig 3 of this paper doesn’t show these; it goes back to the discredited ‘Hockey-Stick’ temp curve of Mann (which even the IPCC no longer uses) that shows no Medieval Warm Period (MWP) or Little Ice Age (LIA),” Singer said. [Editor's Note: In addition, a 2006 peer-reviewed analysis showed the 20th century was not unusually warm.]
Singer also noted, “Actual thermometer data (Polyakov et al) are available for the 20th century; there is no need for indirect proxy data. They show the warmest years in the Arctic around 1935. This can also seen clearly in the CRUTEM data of their Fig 2 (black curve).”
In addition, the new Arctic “Hockey Stick” study appears to contradict numerous previous studies on the Arctic.

Excerpt: New Arctic Study published in Climate Dynamics, and the work was conducted by Håkan Grudd of Stockholm University’s Department of Physical Geography and Quaternary Geology – Published online: 30 January 2008 – Excerpt: “The late-twentieth century is not exceptionally warm in the new Torneträsk record: On decadal-to-century timescales, periods around AD 750, 1000, 1400, and 1750 were all equally warm, or warmer.
January 2008 study in the peer-reviewed journal Science found North Atlantic warming tied to natural variability. Excerpt: A Duke University-led analysis of available records shows that while the North Atlantic Ocean’s surface waters warmed in the 50 years between 1950 and 2000, the change was not uniform. In fact, the sub-polar regions cooled at the same time that subtropical and tropical waters warmed. This striking pattern can be explained largely by the influence of a natural and cyclical wind circulation pattern called the North Atlantic Oscillation (NAO), wrote authors of a study published Thursday, January 3 in Science Express, the online edition of the journal Science. [...] “It is premature to conclusively attribute these regional patterns of heat gain to greenhouse warming,” they wrote.
A November 2007 peer-reviewed study conducted by a team of NASA and university experts found cyclical changes in ocean currents impacting the Arctic. Excerpt: “Our study confirms many changes seen in upper Arctic Ocean circulation in the 1990s were mostly decadal in nature, rather than trends caused by global warming,” said James Morison of the University of Washington’s Polar Science Center Applied Physics Laboratory in Seattle, according to a November 13, 2007 NASA release.
A 2005 peer-reviewed study in Geophysical Research Letters by astrophysicist Dr. Willie Soon, solar irradiance appears to be the key to Arctic temperatures. The study found Arctic temperatures follow the pattern of increasing or decreasing energy received from the sun. Excerpt: Solar forcing explains well over 75% of the variance for the decadally-smoothed Arctic annual-mean or spring SATs (surface air temperatures).
According to a 2003 study by Arctic scientist Igor Polyakov, the warmest period in the Arctic during the 20th Century was the late 1930s through early 1940s. Excerpt: Our results suggest that the decadal AO (Arctic Oscillation) and multidecadal LFO (low-frequency oscillation) drive large amplitude natural variability in the Arctic making detection of possible long-term trends induced by greenhouse gas warming most difficult.

The Post aritlce on the new Arctic study also reported: “The [new Arctic] paper in Science sheds light on several key scientific questions, including how the earth’s orbital pattern around the sun affects our climate, and the extent to which current computer climate models mirror real-world conditions. Some climate skeptics have argued that the fact that the earth wobbles in its axis of rotation has helped determine recent warming, rather than human activities. But the new study shows this wobble — which affects how much sunlight the earth receives in the middle of the summer — actually accounts for a long-term cooling trend in the Arctic, which has only been reversed in the past half-century.”
But geologist Dr. Don J. Easterbrook, Emeritus Professor at Western Washington University, who has authored eight books and 150 journal publications, disputed the findings of new Arctic report. “The glacial record (both advance and retreat history and the isotope data in Greenland ice cores) contrast sharply with the temperature curves shown in this paper,” Easterbrook told Climate Depot. “There is no way that the well documented, short-term climate changes can be orbitally driven because of the vastly longer time scales for orbital changes. Among the big surprises (and most significant) results of the ice core data is that the abrupt, short-term climate changes cannot be possibly be explained by orbital changes,” Easterbrook added.
Singer agreed, noting, “the Abstract tries to relate 20th century temperature changes to insolation changes (Fig 4) and claims these are ‘orbitally’ driven. This is highly unlikely: the temperature changes on a time scale of decades; orbital changes are much slower, and generally measured in millennia. I prefer [Harvard University Astrophysicist] Dr. Willie Soon’s analysis of Arctic temperature changes.”
The Washington Post does at least interview one scientist skeptical of man-made climate claims. The article reported: “Fred Singer, a prominent climate change skeptic who heads the Science and Environmental Policy Project, questioned the Science study on the grounds it does not properly reflect the fact that other researchers have found the Medieval Warm Period — which lasted between 800 and 1,300 A.D. — had ‘higher temperatures than even the past 30 years.’”
Eilperin then goes on to claim that that the “documentation of the Medieval Warm Period is primarily about Europe, and natural records indicate average Arctic temperatures during that time were not as high. There was a brief period in the early fifth century that came close to, but was not quite as warm, as the Arctic’s most recent summer temperatures.”
‘Medieval Warm Period was real, global, and warmer than the present’
How sad, that Eliperin’s refused to do basic research before making such a whopper of a claim. The latest research clearly reveals that the Medieval Warm Period (used to be referred to as the Medieval Climate Optimum) has been verified and was in fact global, not just confined to the Northern Hemisphere. The Center for the Study of Carbon Dioxide and Global Change reported in 2009 that the “Medieval Warm Period was: (1) global in extent, (2) at least as warm as, but likely even warmer than, the Current Warm Period, and (3) of a duration significantly longer than that of the Current Warm Period to date.”
In addition, The Science and Public Policy Institute reported in May 2009: “More than 700 scientists from 400 institutions in 40 countries have contributed peer-reviewed papers providing evidence that the Medieval Warm Period (MWP) was real, global, and warmer than the present. And the numbers grow larger daily.”
After promoting the eco-group World Wildlife Fund’s new climate study, the Washington Post also digs up a scientist with a woeful reputation, Robert Corell, and chooses not to identify his employment with the partisan Heinz Foundation, vice-chaired by Teresa Heinz Kerry, wife of Senator John Kerry (who recently claimed: Global Warming Is The Next 9/11) Eilperin felt compelled to state that Fred Singer was a “skeptic” but the reporter felt no obligation to label any other scientists she cited in the article.
Reporter Eilperin wrote: “Robert Correll, who chairs the Arctic Climate Impact Assessment, said the paper in Science will likely ‘in the long haul become a seminal piece in the scientific literature” because it allows other climate researchers “to set their work in a long time scale.’”
First off, Eilperin misspelled Corell’s name as “Correll.” Second, Eilperin could not find the space in her article to note Corell’s affiliation with former Vice President Al Gore or his role in the left-wing Heinz Center or the fact that Corell, has been under fire for dubious climate claims. In addition, Corell has been linked to an “affiliate” of a Washington, D.C.-based consulting firm that provides “expert testimony” in trials and he was reportedly sponsored by the left-leaning Packard Foundation.
Robert Corell Publicly Rebuked For Incorrect Climate Claims
Most shockingly, Corell was publicly rebuked for incorrect climate claims by a prominent scientist who studies Greenland in 2007. Corell made the assertion that he knew Greenland was being impacted by man-made global warming, stating: “I spent four months on the [Greenland] ice cap in 1968 and there was no melting at all.” Corell did not even attempt to give a balanced historical view of Greenland’s ice and temperature history. (for inconvenient report see: 2007 analysis of peer-reviewed literature debunks fears of Greenland melting)
But Corell’s assertion in a September 8, 2007 UK Guardian article that earthquakes triggered by melting ice are increasing in Greenland was rebuffed by University of North Carolina’s Jose Rial. Rial is a prominent climatologist/seismologist working on glacial seismic activity in Greenland. Corell’s erroneous claim prompted Rial to take the unusual step of writing a letter to the UK Guardian.
“I also know that there is no evidence to suggest that these quakes ‘are happening far faster than ever anticipated’ [as Corell claimed,"] wrote Rial in a September 13, 2007 letter.
Rial criticized the newspaper for presenting a ‘falling-sky’ alarmist perspective and added that “it will take years of continued surveying to know whether anything here [in Greenland] is ‘accelerating’ towards catastrophe, as the article [featuring Corell] claims.”
Corell has also been under fire for his work as the chair of the Arctic Impact Assessment report from 2004. This report was challenged immediately for its computer model generated scary scenarios of an alleged global warming ravaged future Arctic.

Corell currently serves as the Vice President of Programs at The Heinz Center, which gave a $250,000 award to NASA scientist James Hansen in 2001. Corell’s personal relationship with former Vice President Al Gore, allowed him to enjoy a private screening of “An Inconvenient Truth” in 2006. Corell is also on record for giving former Gore’s film two thumbs up for accuracy.
