“Provably False Statements” in Defense of Hockey Stick?
As mentioned last issue, the initial response by University of VIrginia Assistant Professor Michael Mann to the questions raised by Canadian analysts Steven McIntyre and Ross McKitrick over the data underlying the infamous “hockey stick” graph of temperatures over the last 100 years (MBH98) was to allege that his critics had used an incorrect data set. Mann said that they should have used data available on a “public” FTP site.
McIntyre and McKitrick have now replied to this allegation. The summary of their detailed rebuttal (available at http://www.uoguelph.ca/~rmckitri/research/trc.html) states, “We refute suggestions by Professor Mann that collation in the proxy data set criticized in [our paper] were introduced in a special purpose Excel spreadsheet prepared for McIntyre in April 2003…. [W]e have determined that the uncollated series at the Mann FTP site are identical to the versions in the data set we examined and criticized in MM [that is, the paper by McIntyre and McKitrick].
“Accordingly, the criticisms of MM in respect to unjustified truncation and fills, use of obsolete data and geographical mislocations apply equally to the acknowledged MBH98 data archive.”
Referring to the detailed allegations made by Mann on the web site of freelance propagandist David Appell, McIntyre and McKitrick say, “It is self-evident that Mann’s comments are a pastiche of false statements. The rebuttal also relates how the contents of the FTP site were changed without notice between when MM were first informed of the site and Nov. 8.
McIntyre and McKitrick conclude that “Professor Mann’s public comments regarding MM contain many provably false statements.” They also point out that, as data he suggested were “meaningless” are identical to those contained in the FTP site, “Professor Mann himself has made a prima facie case for a new refereeing of MBH98.”
Antarctic Ice Expands while Arctic Contracts
New research from NASA’s Goddard Space Flight Center reveals that a 30-year satellite record of sea ice at the poles shows that while Arctic ice has melted, Antarctic ice has increased in recent years. Although the volume of Antarctic ice has decreased over the entire period, this was due to a dramatic loss of Antarctic sea ice between 1973 and 1977.
The researchers suggest that the greater loss of sea ice in the Arctic “may be due to a general warming trend in the Arctic as well as the influence of long-term oscillations or other changes in atmospheric pressure systems, which could pull in more warm air from the south.”
In the Antarctic, the researchers say, “The gradual advance of ice from the late 1970s may be related to long-term atmospheric oscillations in the Southern Hemisphere resulting in stronger westerly winds and cooler temperatures.”
Co-author Claire Parkinson of NASA said, “Trying to explain why these things happen becomes tricky. The temperature connection where warmer temperatures lead to greater melt is reasonably direct, but far from the complete story. Winds and waves move ice around, and consequently the ice can move to places where it is warm enough that it wouldn’t have formed.”
The lead author of the study, NASA’s Don Cavalieri, said, “It seems the two regions are responding to different hemispheric variations. What remains is to sift out and understand how these variations are driving the sea ice in each hemisphere.” (Eurekalert, Nov. 12)
More Problems for Hydrogen Technology
A New York Times article on November 12 pointed out that, “Even some hydrogen advocates say that use of hydrogen could instead make the air dirtier and the globe warmer.”
The paper points out that the most cost-effective way to produce hydrogen involves the burning of coal, rather than using renewable energy sources, and quoted Ronald Kenedi, Managing Director of Sharp Solar, as saying, “It seems like hydrogen is the buzz word right now, with the president talking about it, and maybe putting some money towards it. But the first stop on the hydrogen trail will be coal.”
According to the article, carbon dioxide emissions are a problem: “According to the Energy Department, an ordinary gasoline-powered car emits 374 grams of carbon dioxide per mile it is driven, counting the energy used to make the gasoline and deliver it to the service station, and the emissions of the vehicle itself. The same car powered by a fuel cell would emit nothing, but if the energy required to make the hydrogen came from the electric grid, the emissions would be 436 grams per mile, 17 percent worse than the figure for gasoline.”
The Times also found the cost problematic: “Reuel Shinnar, a professor of chemical engineering at City College of New York, reviewing the options for power production and fuel production, concluded in a recent paper, ‘A hydrogen economy is at least twice as expensive as any other solution.'”
The Next Ice Age is a Real Problem
Continuing with our New York Times-theme issue, the Times’s Tuesday science section celebrated its 25th anniversary on November 11 by running short articles on “25 of the most provocative questions facing science.” Surprisingly, global warming was not on the list, but, “When is the next ice age?” was addressed by veteran Times science writer Andrew C. Revkin.
“The next ice age almost certainly will reach itspeak in about 80,000 years,” wrote Revkin, “but debate persists about how soon it will begin, with the latest theory being that the human influence on the atmosphere may substantially delay the transition.”
Since the next ice age would be a calamity for human civilization, “It would seem that human-driven global warming, although perhaps a disaster on the scale of centuries, may be a good thing in the long run if it fends off the next ice age.” So those who really care about, as former President Bill Clinton might have put it, their children’s children’s children’s descendant’s grandchildren should be burning a lot of gasoline in their Ford Excursions and GM Hummers.
Now Here’s a Really Scary Future
According to a former United Kingdom environment minister, environmental apocalypse is imminent and the solution is–a world environment court!
“The most important issue is enforceability…. What is really needed is a world environment court,” wrote Michael Meacher, MP, in London’s Guardian on October 25. Meacher served as environment minister in the Blair Government from 1997 until he was fired earlier this year.
Meacher continued: “The right to bring cases before such a court should not be confined to the governments of nation states, but should include public interest bodies, notably NGOs. The court should also have permanent specialist bodies to investigate damage to the global environment, whether inflicted or threatened, with powers to subpoena evidence and prosecute individuals and corporate bodies. This would only work if properly funded. However, if the fines imposed on corporate offenders were recycled, the court’s investigative and legal work would quickly become self-financing.”
Raise a Glass to a Warmer World
Many news outlets carried the story in early November that Southern Oregon University researcher Gregory Jones had ascertained that global warming would be good for wine harvests.
According to his press release, “Jones and his colleagues used records of Sotheby’s 100-point vintage rating scale data (where wines scoring over 90 are ‘excellent to superb’ and under 40 are ‘disastrous’) along with climate records dating back to 1950 to look for trends in wine quality or growing season temperatures. What they found was an average temperature rise of 2C rise over the past 50 years and higher vintage ratings.
“‘There were no negative impacts,’ Jones said of the apparent temperature rise in the world’s most renowned wine producing regions.”
