Re: The world has never seen such freezing heat
It is amazing how circular many of the 'consensus' arguments are getting.
Another data point:
Of course, the Inhofe's blog isn't exactly a 'peer reviewed' journal.

Another article from Inhofe's blog lists more of these 'peer reviewed' studies which contradict the MMGW view.
Again, not clear which is right - the key is to read into it and try to understand the arguments.

Over 400 prominent scientists from more than two dozen countries recently voiced significant objections to major aspects of the so-called "consensus" on man-made global warming. These scientists, many of whom are current and former participants in the UN IPCC (Intergovernmental Panel on Climate Change), criticized the climate claims made by the UN IPCC and former Vice President Al Gore.
The new report issued by the Senate Environment and Public Works Committee's office of the GOP Ranking Member details the views of the scientists, the overwhelming majority of whom spoke out in 2007.
Even some in the establishment media now appear to be taking notice of the growing number of skeptical scientists. In October, the Washington Post Staff Writer Juliet Eilperin conceded the obvious, writing that climate skeptics "appear to be expanding rather than shrinking." Many scientists from around the world have dubbed 2007 as the year man-made global warming fears "bite the dust." (LINK) In addition, many scientists who are also progressive environmentalists believe climate fear promotion has "co-opted" the green movement. (LINK)

1) New peer-reviewed study finds global warming over last century linked to natural causes: Published in Geophysical Research Letters: Excerpt: “Tsonis et al. investigate the collective behavior of known climate cycles such as the Pacific Decadal Oscillation, the North Atlantic Oscillation, the El Nino/Southern Oscillation, and the North Pacific Oscillation. By studying the last 100 years of these cycles' patterns, they find that the systems synchronized several times. Further, in cases where the synchronous state was followed by an increase in the coupling strength among the cycles, the synchronous state was destroyed. Then a new climate state emerged, associated with global temperature changes and El Nino/Southern Oscillation variability. The authors show that this mechanism explains all global temperature tendency changes and El Nino variability in the 20th century. Authors: Anastasios A. Tsonis, Kyle Swanson, and Sergey Kravtsov: Atmospheric Sciences Group, Department of Mathematical Sciences, University of Wisconsin-Milwaukee, Milwaukee, Wisconsin, U.S.A.

2) Belgian weather institute’s (RMI) August 2007 study dismisses decisive role of CO2 in warming: Excerpt: "Brussels: CO2 is not the big bogeyman of climate change and global warming. This is the conclusion of a comprehensive scientific study done by the Royal Meteorological Institute, which will be published this summer. The study does not state that CO2 plays no role in warming the earth. "But it can never play the decisive role that is currently attributed to it", climate scientist Luc Debontridder said. "Not CO2, but water vapor is the most important greenhouse gas. It is responsible for at least 75 % of the greenhouse effect. This is a simple scientific fact, but Al Gore's movie has hyped CO2 so much that nobody seems to take note of it." said Debontridder. "Every change in weather conditions is blamed on CO2. But the warm winters of the last few years (in Belgium) are simply due to the 'North-Atlantic Oscillation'. And this has absolutely nothing to do with CO2," he added. (LINK)
3) Updated: September 27, 2007: New peer-reviewed study counters global warming theory, finds carbon dioxide did not end the last Ice Age. Excerpt: Deep-sea temperatures rose 1,300 years before atmospheric CO2, ruling out the greenhouse gas as driver of meltdown, says study in Science. Carbon dioxide did not cause the end of the last ice age, a new study in Science suggests, contrary to past inferences from ice core records. “There has been this continual reference to the correspondence between CO2 and climate change as reflected in ice core records as justification for the role of CO2 in climate change,” said USC geologist Lowell Stott, lead author of the study, slated for advance online publication Sept. 27 in Science Express. “You can no longer argue that CO2 alone caused the end of the ice ages.” Deep-sea temperatures warmed about 1,300 years before the tropical surface ocean and well before the rise in atmospheric CO2, the study found. The finding suggests the rise in greenhouse gas was likely a result of warming and may have accelerated the meltdown – but was not its main cause. < > “The climate dynamic is much more complex than simply saying that CO2 rises and the temperature warms,” Stott said. The complexities “have to be understood in order to appreciate how the climate system has changed in the past and how it will change in the future.” (LINK)
4) New peer-reviewed study finds clouds may greatly reduce global warming: Excerpt: This study published on August 9, 2007 in the Geophysical Research Letters finds that climate models fail test against real clouds. "To give an idea of how strong this enhanced cooling mechanism is, if it was operating on global warming, it would reduce estimates of future warming by over 75 percent," Dr. Roy Spencer said. "At least 80 percent of the Earth's natural greenhouse effect is due to water vapor and clouds, and those are largely under the control of precipitation systems. Until we understand how precipitation systems change with warming, I don't believe we can know how much of our current warming is manmade. Without that knowledge, we can't predict future climate change with any degree of certainty," Spencer added. The paper was co-authored by University of Alabama Huntsville's Dr. John R. Christy and Dr. W. Danny Braswell, and Dr. Justin Hnilo of Lawrence Livermore National Laboratory, Livermore, CA. (LINK)
5) New peer-reviewed study finds that the solar system regulates the earth’s climate - The paper, authored by Richard Mackey, was published August 17, 2007 in the Journal of Coastal Research - Excerpt: “According to the findings reviewed in this paper, the variable output of the sun, the sun’s gravitational relationship between the earth (and the moon) and earth’s variable orbital relationship with the sun, regulate the earth’s climate. The processes by which the sun affects the earth show periodicities on many time scales; each process is stochastic and immensely complex. (LINK) & (LINK)
6) New peer-reviewed study on Surface Warming and the Solar Cycle: Excerpt: The study found that times of high solar activity are on average 0.2 degrees C warmer than times of low solar activity, and that there is a polar amplification of the warming. This result is the first to document a statistically significant globally coherent temperature response to the solar cycle, the authors note. Authors: Charles D. Camp and Ka Kit Tung: Department of Applied Mathematics, University of Washington, Seattle, Washington, U.S.A.

7) Update - August 29, 2007: SURVEY: LESS THAN HALF OF ALL PUBLISHED SCIENTISTS ENDORSE GLOBAL WARMING THEORY - Excerpt: "Of 539 total papers on climate change, only 38 (7%) gave an explicit endorsement of the consensus. If one considers 'implicit' endorsement (accepting the consensus without explicit statement), the figure rises to 45%. However, while only 32 papers (6%) reject the consensus outright, the largest category (48%) are neutral papers, refusing to either accept or reject the hypothesis. This is no 'consensus.'"(LINK) A July 2007 review of 539 abstracts in peer-reviewed scientific journals from 2004 through 2007 found that climate science continues to shift toward the views of global warming skeptics. Excerpt: “There appears to be little evidence in the learned journals to justify the climate-change alarm.” (LINK)
8) Chinese scientists Lin Zhen-Shan, and Sun Xian’s 2007 study, published in the peer-reviewed Meteorology and Atmospheric Physics, noted that CO2’s impact on warming may be “excessively exaggerated.” Excerpt: “The global climate warming is not solely affected by the CO2 greenhouse effect. The best example is temperature obviously cooling however atmospheric CO2 concentration is ascending from 1940s to 1970s. Although the CO2 greenhouse effect on global climate change is unsuspicious, it could have been excessively exaggerated. It is high time to reconsider the trend of global climate change,” the two scientists concluded. (LINK) & (LINK)
9) Updated: October 2, 2007: Danish National Space Center Study concludes: “The Sun still appears to be the main forcing agent in global climate change.” The report was authored by Physicist Henrik Svensmark and Eigil Friis-Christensen. (LINK) Several other recent scientific studies and scientists have debunked a media hyped UK study alleging there has not been a solar-climate link in the past 20 years. UK Astrophysicist Piers Corbyn confirmed the Danish study and also debunked the “No Solar-Climate Link Study” on July 14, 2007. Excerpt: “[The study claiming to prove a] ‘refutation’ of the decisive role of solar activity in driving climate is as valid as claiming a particular year was not warm by simply looking at the winter half of data. The most significant and persistent cycle of variation in the world’s temperature follows the 22-year magnetic cycle of the sun’s activity,” Corbyn, who heads the UK based long-term solar forecast group Weather Action, wrote.

10) A June 29, 2007 critique by Gerd Burger of Berlin’s Institute of Meteorology in the peer-reviewed Science Magazine challenged a previously touted study claiming the 20th century had been unusually warm. Excerpt: “Burger argues that [the 2006 temperature analysis by] Osborn and Briffa did not apply the appropriate statistical tests that link the proxy records to observational data, and as such, Osborn and Briffa did not properly quantify the statistical uncertainties in their analyses. Burger repeated all analyses with the appropriate adjustments and concluded “As a result, the ‘highly significant’ occurrences of positive anomalies during the 20th century disappear.” (LINK) Burger's technical comments in Science Magazine state: “Osborn and Briffa (Reports, 10 February 2006, p. 841) identified anomalous periods of warmth or cold in the Northern Hemisphere that were synchronous across 14 temperature-sensitive proxies. However, their finding that the spatial extent of 20th-century warming is exceptional ignores the effect of proxy screening on the corresponding significance levels. After appropriate correction, the significance of the 20th-century warming anomaly disappears.” (LINK)
11) An April 2007 study revealed the Earth’s climate “seesawing” during the last 10,000 years, according to Swedish researchers Svante Björck, Karl Ljung and Dan Hammarlund of Lund University. Excerpt: During the last 10,000 years climate has been seesawing between the North and South Atlantic Oceans. As revealed by findings presented by Quaternary scientists at Lund University, Sweden, cold periods in the north have corresponded to warmth in the south and vice verse. These results imply that Europe may face a slightly cooler future than predicted by IPCC, the Intergovernmental Panel on Climate Change. < > We can identify a persistent "seesaw" pattern. When the South Atlantic was warm it was cold in the North Atlantic and vice versa. This is most certainly related to large-scale ocean circulation in the Atlantic Ocean. The main current system - "the Great Ocean Conveyor" - is driven by sinking of dense, relatively cold and salty water in the northern North Atlantic. This results in southward-flowing deep-water that is replaced by warm surface water brought to high northern latitudes from the tropics and ultimately from the South Atlantic, says Svante Björck. < > Our results from Nightingale Island in the Tristan da Cunha island group, between South Africa and Argentina, for the first time give evidence of warming of the South Atlantic associated with cooling in the north. This is a major breakthrough in palaeoclimate research. (LINK)
12) An August 2007 NASA temperature data error discovery has lead to 1934 -- not the previously hyped 1998 -- being declared the hottest in U.S. history since records began. Revised data now reveals four of the top ten hottest years in the U.S. were in the 1930's while only three of the hottest years occurred in the last decade. Excerpt: "NASA has yet to own up fully to its historic error in misinterpreting US surface temperatures to conform to the Global Warming hypothesis, as discovered by Stephen McIntyre at ClimateAudit.org." (LINK) [EPW Blog note: 80% of man-made CO2 emissions occurred after 1940. (LINK) ]
13) Numerous U.S. temperature collection data errors exposed by team of researchers led by Meteorologist Anthony Watts in 2007 (LINK) - “The (U.S.) National Climate Data Center (NCDC) is in the middle of a scandal. Their global observing network, the heart and soul of surface weather measurement, is a disaster. Urbanization has placed many sites in unsuitable locations — on hot black asphalt, next to trash burn barrels, beside heat exhaust vents, even attached to hot chimneys and above outdoor grills! The data and approach taken by many global warming alarmists is seriously flawed. If the global data were properly adjusted for urbanization and station siting, and land use change issues were addressed, what would emerge is a cyclical pattern of rises and falls with much less of any background trend,” Meteorologist Joseph Conklin wrote in an August 10, 2007 blog post. (LINK)
14) Team of Scientists Question Validity Of A 'Global Temperature' – The study was published in Journal of Non-Equilibrium Thermodynamics. Excerpt from a March 18, 2007 article in Science Daily: “Discussions on global warming often refer to 'global temperature.' Yet the concept is thermodynamically as well as mathematically an impossibility, says Bjarne Andresen, a professor at The Niels Bohr Institute, University of Copenhagen, who has analyzed this topic in collaboration with professors Christopher Essex from University of Western Ontario and Ross McKitrick from University of Guelph, Canada.” The Science Daily article reads: "It is impossible to talk about a single temperature for something as complicated as the climate of Earth", Bjarne Andresen says, an expert of thermodynamics. "A temperature can be defined only for a homogeneous system. Furthermore, the climate is not governed by a single temperature. Rather, differences of temperatures drive the processes and create the storms, sea currents, thunder, etc. which make up the climate.” He explains that while it is possible to treat temperature statistically locally, it is meaningless to talk about a global temperature for Earth. The Globe consists of a huge number of components which one cannot just add up and average. That would correspond to calculating the average phone number in the phone book. That is meaningless. Or talking about economics, it does make sense to compare the currency exchange rate of two countries, whereas there is no point in talking about an average 'global exchange rate.’” The article concludes: “Thus claims of disaster may be a consequence of which averaging method has been used, the researchers point out.” (LINK)
15) Updated: September 26, 2007: New Report from the international group Institute of Physics’ finds no “consensus” on global warming. Excerpt: As world leaders gathered in New York for a high-level UN meeting on climate change, a new report by some of the world's most renowned scientists urges policymakers to keep their eyes on the "science grapevine", arguing that their understanding of global warming is still far from complete. Recognizing that powerful computer-based simulations are a key element in predicting climate change, a new Institute of Physics (IOP) report, published on 26 September 2007, shows that leading climate-physicists' views on the reliability of these models differ. The IOP is also urging world leaders "to remain alert to the latest scientific thought on climate change". (LINK)
16) A July 2007 analysis of peer-reviewed literature thoroughly debunks fears of Greenland and the Arctic melting and predictions of a frightening sea level rise. Excerpt: "Research in 2006 found that Greenland has been warming since the 1880’s, but since 1955, temperature averages at Greenland stations have been colder than the period between 1881-1955. A 2006 study found Greenland has cooled since the 1930's and 1940's, with 1941 being the warmest year on record. Another 2006 study concluded Greenland was as warm or warmer in the 1930’s and 40’s and the rate of warming from 1920-1930 was about 50% higher than the warming from 1995-2005. One 2005 study found Greenland gaining ice in the interior higher elevations and thinning ice at the lower elevations. In addition, the often media promoted fears of Greenland’s ice completely melting and a subsequent catastrophic sea level rise are directly at odds with the latest scientific studies."

17) Update - September 11, 2007: Antarctic ice GROWS to record levels. Excerpt: While the news focus has been on the lowest ice extent since satellite monitoring began in 1979 for the Arctic, the Southern Hemisphere (Antarctica) has quietly set a new record for most ice extent since 1979. This can be seen on this graphic from this University of Illinois site The Cryosphere Today, which updated snow and ice extent for both hemispheres daily. The Southern Hemispheric areal coverage is the highest in the satellite record, just beating out 1995, 2001, 2005 and 2006. Since 1979, the trend has been up for the total Antarctic ice extent. < > This winter has been an especially harsh one in the Southern Hemisphere with cold and snow records set in Australia, South America and Africa. (LINK) & (LINK) A February 2007 study reveals Antarctica is not following predicted global warming models. Excerpt: “A new report on climate over the world's southernmost continent shows that temperatures during the late 20th century did not climb as had been predicted by many global climate models." The research was led by David Bromwich, professor of professor of atmospheric sciences in the Department of Geography, and researcher with the Byrd Polar Research Center at Ohio State University.

18) Update - September 14, 2007: A soon to be released survey finds Polar Bear population rising in warmer part of the Arctic. Excerpt: Fears that two-thirds of the world’s polar bears will die off in the next 50 years are overblown, says [Arctic biologist] Mitchell Taylor, the Government of Nunavut’s director of wildlife research. “I think it’s naïve and presumptuous,” Taylor said. < > The Government of Nunavut is conducting a study of the [southern less ice region of the] Davis Strait bear population. Results of the study won’t be released until 2008, but Taylor says it appears there are some 3,000 bears in an area - a big jump from the current estimate of about 850 bears. “That’s not theory. That’s not based on a model. That’s observation of reality,” he says. And despite the fact that some of the most dramatic changes to sea ice is seen in seasonal ice areas such as Davis Strait, seven or eight of the bears measured and weighed for the study this summer are among the biggest on record, Taylor said. “Davis Strait is crawling with polar bears. It's not safe to camp there. They're fat. The mothers have cubs. The cubs are in good shape,” Taylor said, according to a September 14, 2007 article. (LINK) [EPW Blog Note: In a classic case of observed reality versus unproven computer model predictions, the U.S. Fish & Wildlife Service estimates that the polar bear population is currently at 20,000 to 25,000 bears, up from as low as 5,000-10,000 bears in the 1950s and 1960s. A 2002 U.S. Geological Survey of wildlife in the Arctic Refuge Coastal Plain noted that the polar bear populations ‘may now be near historic highs.’ ]
19) Even the alarmist UN has cut sea level rise estimates dramatically since 2001 and has reduced man’s estimated impact on the climate by 25%. Meanwhile a separate 2006 UN report found that cow emissions are more damaging to the planet than all of the CO2 emissions from cars and trucks. (LINK)
20) Update - September 10, 2007: New study claims UN IPCC peer-review process is "an illusion." A September 2007 analysis of the IPCC (Intergovernmental Panel on Climate Change) scientific review process entitled “Peer Review? What Peer Review?” by climate data analyst John McLean, revealed very few scientists are actively involved in the UN's peer-review process. According to the analysis, “The IPCC would have us believe that its reports are diligently reviewed by many hundreds of scientists and that these reviewers endorse the contents of the report. Analyses of reviewer comments show a very different and disturbing story.” The paper continued: "In [the IPCC's] Chapter 9, the key science chapter, the IPCC concludes that 'it is very highly likely that greenhouse gas forcing has been the dominant cause of the observed global warming over the last 50 years.' The IPCC leads us to believe that this statement is very much supported by the majority of reviewers. The reality is that there is surprisingly little explicit support for this key notion. Among the 23 independent reviewers just 4 explicitly endorsed the chapter with its hypothesis, and one other endorsed only a specific section. Moreover, only 62 of the IPCC’s 308 reviewers commented on this chapter at all." The analysis concluded: “The IPCC reports appear to be largely based on a consensus of scientific papers, but those papers are the product of research for which the funding is strongly influenced by previous IPCC reports. This makes the claim of a human influence self-perpetuating and for a corruption of the normal scientific process.” (LINK)

Excerpt: "NASA has yet to own up fully to its historic error in misinterpreting US surface temperatures to conform to the Global Warming hypothesis, as discovered by Stephen McIntyre at ClimateAudit.org."

13) Numerous U.S. temperature collection data errors exposed by team of researchers led by Meteorologist Anthony Watts in 2007 (LINK) - “The (U.S.) National Climate Data Center (NCDC) is in the middle of a scandal. Their global observing network, the heart and soul of surface weather measurement, is a disaster. Urbanization has placed many sites in unsuitable locations — on hot black asphalt, next to trash burn barrels, beside heat exhaust vents, even attached to hot chimneys and above outdoor grills! The data and approach taken by many global warming alarmists is seriously flawed. If the global data were properly adjusted for urbanization and station siting, and land use change issues were addressed, what would emerge is a cyclical pattern of rises and falls with much less of any background trend,” Meteorologist Joseph Conklin wrote in an August 10, 2007 blog post.

14) Team of Scientists Question Validity Of A 'Global Temperature' – The study was published in Journal of Non-Equilibrium Thermodynamics. Excerpt from a March 18, 2007 article in Science Daily: “Discussions on global warming often refer to 'global temperature.' Yet the concept is thermodynamically as well as mathematically an impossibility, says Bjarne Andresen, a professor at The Niels Bohr Institute, University of Copenhagen, who has analyzed this topic in collaboration with professors Christopher Essex from University of Western Ontario and Ross McKitrick from University of Guelph, Canada.” The Science Daily article reads: "It is impossible to talk about a single temperature for something as complicated as the climate of Earth", Bjarne Andresen says, an expert of thermodynamics. "A temperature can be defined only for a homogeneous system. Furthermore, the climate is not governed by a single temperature. Rather, differences of temperatures drive the processes and create the storms, sea currents, thunder, etc. which make up the climate.” He explains that while it is possible to treat temperature statistically locally, it is meaningless to talk about a global temperature for Earth. The Globe consists of a huge number of components which one cannot just add up and average. That would correspond to calculating the average phone number in the phone book. That is meaningless. Or talking about economics, it does make sense to compare the currency exchange rate of two countries, whereas there is no point in talking about an average 'global exchange rate.’” The article concludes: “Thus claims of disaster may be a consequence of which averaging method has been used, the researchers point out.” (LINK)
15) Updated: September 26, 2007: New Report from the international group Institute of Physics’ finds no “consensus” on global warming. Excerpt: As world leaders gathered in New York for a high-level UN meeting on climate change, a new report by some of the world's most renowned scientists urges policymakers to keep their eyes on the "science grapevine", arguing that their understanding of global warming is still far from complete. Recognizing that powerful computer-based simulations are a key element in predicting climate change, a new Institute of Physics (IOP) report, published on 26 September 2007, shows that leading climate-physicists' views on the reliability of these models differ. The IOP is also urging world leaders "to remain alert to the latest scientific thought on climate change". (LINK)
16) A July 2007 analysis of peer-reviewed literature thoroughly debunks fears of Greenland and the Arctic melting and predictions of a frightening sea level rise. Excerpt: "Research in 2006 found that Greenland has been warming since the 1880’s, but since 1955, temperature averages at Greenland stations have been colder than the period between 1881-1955. A 2006 study found Greenland has cooled since the 1930's and 1940's, with 1941 being the warmest year on record. Another 2006 study concluded Greenland was as warm or warmer in the 1930’s and 40’s and the rate of warming from 1920-1930 was about 50% higher than the warming from 1995-2005. One 2005 study found Greenland gaining ice in the interior higher elevations and thinning ice at the lower elevations. In addition, the often media promoted fears of Greenland’s ice completely melting and a subsequent catastrophic sea level rise are directly at odds with the latest scientific studies."

17) Update - September 11, 2007: Antarctic ice GROWS to record levels. Excerpt: While the news focus has been on the lowest ice extent since satellite monitoring began in 1979 for the Arctic, the Southern Hemisphere (Antarctica) has quietly set a new record for most ice extent since 1979. This can be seen on this graphic from this University of Illinois site The Cryosphere Today, which updated snow and ice extent for both hemispheres daily. The Southern Hemispheric areal coverage is the highest in the satellite record, just beating out 1995, 2001, 2005 and 2006. Since 1979, the trend has been up for the total Antarctic ice extent. < > This winter has been an especially harsh one in the Southern Hemisphere with cold and snow records set in Australia, South America and Africa. (LINK) & (LINK) A February 2007 study reveals Antarctica is not following predicted global warming models. Excerpt: “A new report on climate over the world's southernmost continent shows that temperatures during the late 20th century did not climb as had been predicted by many global climate models." The research was led by David Bromwich, professor of professor of atmospheric sciences in the Department of Geography, and researcher with the Byrd Polar Research Center at Ohio State University.

18) Update - September 14, 2007: A soon to be released survey finds Polar Bear population rising in warmer part of the Arctic. Excerpt: Fears that two-thirds of the world’s polar bears will die off in the next 50 years are overblown, says [Arctic biologist] Mitchell Taylor, the Government of Nunavut’s director of wildlife research. “I think it’s naïve and presumptuous,” Taylor said. < > The Government of Nunavut is conducting a study of the [southern less ice region of the] Davis Strait bear population. Results of the study won’t be released until 2008, but Taylor says it appears there are some 3,000 bears in an area - a big jump from the current estimate of about 850 bears. “That’s not theory. That’s not based on a model. That’s observation of reality,” he says. And despite the fact that some of the most dramatic changes to sea ice is seen in seasonal ice areas such as Davis Strait, seven or eight of the bears measured and weighed for the study this summer are among the biggest on record, Taylor said. “Davis Strait is crawling with polar bears. It's not safe to camp there. They're fat. The mothers have cubs. The cubs are in good shape,” Taylor said, according to a September 14, 2007 article. (LINK) [EPW Blog Note: In a classic case of observed reality versus unproven computer model predictions, the U.S. Fish & Wildlife Service estimates that the polar bear population is currently at 20,000 to 25,000 bears, up from as low as 5,000-10,000 bears in the 1950s and 1960s. A 2002 U.S. Geological Survey of wildlife in the Arctic Refuge Coastal Plain noted that the polar bear populations ‘may now be near historic highs.’ ]
19) Even the alarmist UN has cut sea level rise estimates dramatically since 2001 and has reduced man’s estimated impact on the climate by 25%. Meanwhile a separate 2006 UN report found that cow emissions are more damaging to the planet than all of the CO2 emissions from cars and trucks. (LINK)
20) Update - September 10, 2007: New study claims UN IPCC peer-review process is "an illusion." A September 2007 analysis of the IPCC (Intergovernmental Panel on Climate Change) scientific review process entitled “Peer Review? What Peer Review?” by climate data analyst John McLean, revealed very few scientists are actively involved in the UN's peer-review process. According to the analysis, “The IPCC would have us believe that its reports are diligently reviewed by many hundreds of scientists and that these reviewers endorse the contents of the report. Analyses of reviewer comments show a very different and disturbing story.” The paper continued: "In [the IPCC's] Chapter 9, the key science chapter, the IPCC concludes that 'it is very highly likely that greenhouse gas forcing has been the dominant cause of the observed global warming over the last 50 years.' The IPCC leads us to believe that this statement is very much supported by the majority of reviewers. The reality is that there is surprisingly little explicit support for this key notion. Among the 23 independent reviewers just 4 explicitly endorsed the chapter with its hypothesis, and one other endorsed only a specific section. Moreover, only 62 of the IPCC’s 308 reviewers commented on this chapter at all." The analysis concluded: “The IPCC reports appear to be largely based on a consensus of scientific papers, but those papers are the product of research for which the funding is strongly influenced by previous IPCC reports. This makes the claim of a human influence self-perpetuating and for a corruption of the normal scientific process.” (LINK)
