Satellite Data under Fire Again
Satellite readings of atmospheric temperature have long been a thorn in the side of greenhouse theorists, because they fail to show atmospheric warming at the level their theory demands. A new study manipulates the current data to provide that warming trend. Konstantin Vinnikov of the University of Maryland and Norman Grody of the National Oceanic and Atmospheric Administration published a paper on scienceexpress.org, the online supplement to Science magazine on September 11, in which they calculate that the lower atmosphere has warmed by 0.5 F per decade since 1978.
The findings have been attacked not only by John Christy of the University of Alabama at Huntsville, who along with colleague Roy Spencer produces the generally-accepted satellite temperature data, but also by Frank Wentz of Remote Sensing Systems in California, which has published data that finds more of a warming trend than Christy’s data. Wentz told the Wall Street Journal (Sep. 12), “It just adds noise to the whole debate.”
Christy went further, saying, “I think it’s a paper that should not have been published … There are many fatal problems with it.” The principal objection is that Vinnikov and Grody did not correct the measurements for inaccuracies introduced by the heating up of the satellites by the sun. “They allowed it to remain in the data,” he told Cox News (Sept. 12), “and it corrupted all of their calculations, like a computer virus.” Grody responded that he did not think Christy should have made the adjustments. He did not address the objection that Christy’s data are closely corroborated by weather balloon measurements.
Michael Mann, an assistant professor of environmental sciences at the University of Virginia who has recently played historian in an attempt to back up his claim that 20th century warming was unprecedented in human history, took on the role of satellite expert in the Cox News story. He said, “It becomes increasingly difficult for climate change ‘contrarians’ to try to make the argument, as they often do, that this satellite information in any way calls into question the far more robust ground observations.”
European Flooding Not Unusual
European headlines in the summer of 2002 were dominated by the news of severe flooding across central Europe. The Vltava flooded the Czech capital of Prague and its floodwaters then caused the Elbe to break its banks in Dresden and other German cities. Five years earlier, the river Oder had caused similar problems in Germany, Poland and the Czech Republic. The media and politicians pointed the finger of blame firmly at global climate change, with the clear implication being that something new was at work and things could only get worse.
New research from Michael Mudelsee and colleagues from the University of Leipzig published in Nature (Sept. 11) looks at data reaching as far back as 1021 (for the Elbe) and 1269 (for the Oder). They conclude that there is no upward trend in the incidence of extreme flooding in this region of central Europe.
The researchers write, “For the past 80 to 150 [years], we find a decrease in winter flood occurrence in both rivers, while summer floods show no trend, consistent with trends in extreme precipitation occurrence. The reduction in winter flood occurrence can partly be attributed to fewer events of strong freezing-following such events, breaking river ice at the end of the winter may function as a water barrier and enhance floods severely. Additionally, we detect significant long-term changes in flood occurrence rates in the sixteenth to nineteenth centuries, and conclude that reductions in river length, construction of reservoirs and deforestation have had minor effects on flood frequency.”
UK Met Office Gives Everyone a Climate Model
Taking a leaf from another scientific quest for something of which there is no scientific evidence, SETI-the Search for Extra-Terrestrial Intelligence, the UK Meteorological Office has decided to enlist the public’s help in refining its data. They have released a computer program that runs a version of their climate model on a desktop computer, enabling the Met Office to assess its performance. The model will produce different results depending on what information is fed into it. By having the model run on a great many machines, the researchers will get a better idea of the range of results it produces and how they are distributed.
The reasoning behind the decision reveals one of the biggest problems with climate models, that their interpretation is largely guesswork. “We can’t predict which versions of the model will be any good without running these simulations, and there are far too many for us to run them ourselves,” Dr Myles Allen of Oxford University told Reuters. “Together, participants’ results will give us an overall picture of how much human influence has contributed to recent climate change and the range of possible changes in the future,” he added.
The model can be downloaded from www.climateprediction.net, but needs a fairly modern computer to run. Several early downloaders have noted that it cannot be manipulated and provides little value to anyone running it. Some disruption to internet connections has also been reported.
Russian Scientists Question Alarmism
In an article dated September 9th for Novosti, the official Russian information agency, Alexander Frolov, deputy head of Russia’s Federal Service for Hydrometeorology and Environmental Monitoring, stated baldly that, “Russia does not believe in apocalyptic forecasts” of global warming.
He wrote, “The “grimaces” of climate are due mainly to natural fluctuations, with man-made causes having only a partial effect. On the other hand, the climatic system is incredibly complex, depends on many factors, and is driven by direct and reverse forces that turn cause into effect and back again, and so are hard to translate into credible quantitative estimates of ongoing changes.” He went on, “I am not one inclined towards extreme views. Surely, one should take note of the climate warming, adopt preventive measures, evacuate people from risk zones, restore the rivers to their normal regimens, make adaptations, etc. Fluctuations that we observe are in effect random events resulting in an increasingly unstable climatic system. Growing instability, however, actually means only the possibility, not the inevitability, of some or other change.”
Meanwhile, according to co2science.org, “In a recent discussion published in the Russian journal Geomagnetizm i Aeronomiya (Vol. 43, pp. 132-135), two scientists from the Institute of Solar-Terrestrial Physics of the Siberian Division of the Russian Academy of Sciences challenge the politically-correct global warming dogma that vexes the entire world. Bashkirtsev and Mashnich (2003) say that ‘a number of publications report that the anthropogenic impact on the Earth’s climate is an obvious and proven fact,’ when in actuality, in their opinion, ‘none of the investigations dealing with the anthropogenic impact on climate convincingly argues for such an impact.'”
The Russians commend the work of Friis-Christensen and Lassen on the correlation between sunspot activity and climate and back it up with their own research. They find such a close correlation that they are able to predict that because of the lessening activity over the next few solar cycles, the Earth may enter a cooling phase. Indeed, they say, “The available data of observations support our inference about the cooling that has already started,” because “the average annual air temperature in Irkutsk, which correlates well with the average annual global temperature of the surface air, attained in 1997 its maximum equal to +2.3C” and afterwards “began to diminish to +1.2C in 1998, +0.7C in 1999, and +0.4C in 2000.”
Etc.
From the Miami Herald’s Cancun edition for September 12 comes this gem from a page 3 “point of view” column by Tere Carpinelli of Le Voz de Mexico:
“Believe it or not, one expert even believes that millions of menopausal Baby Boomer women are partly to blame for the rise in the Earth’s temperature! ‘There are more than 900 million middle-aged women worldwide in the early stages of menopause who are experiencing what are commonly known as hot flashes on a regular basis,’ professor of meteorology Dr. Cyrill Sanders told a convention of environmental experts in Osaka, Japan. “That is why the Earth is warming at an increasing rate and there is no end in sight. Sanders said he and his team discovered a clear correlation between the number of women entering menopause over the past 25 years and steadily increasing temperatures.”
As far as we can tell, the source of this ridiculous claim was an August 19 issue of Weekly World News, which ranks below Scientific American for credibility. Perhaps Carpinelli was not sure that this was a joke because of the constant confounding, perpetuated by environmental groups, of correlation and causality.
