Sea Ice Thickens; Junk Science in Science

Sea Ice Thickens

On August 19, 2000 the New York Times published a front-page story claiming that open sea sighted by Dr. James J. McCarthy director of the Museum of Comparative Zoology at Harvard University, at the North Pole was clear evidence of global warming.

The story implied that this hasnt occurred since the Eocene epoch 55 million years ago. McCarthy described the reaction to the sighting, “There was a sense of alarm. Global warming was real, and we were seeing its effects for the first time that far north.”

Ten days later the Times ran a retraction in a Science Times article that quoted Dr. Mark Serreze, a climatologist at the National Snow and Ice Data Center in Boulder, Colo., as saying, “Theres nothing to be necessarily alarmed about. Theres been open water at the pole before. We have no clear evidence at this point that this is related to global climate change.”

Perhaps due to this embarrassing gaffe, the New York Times is shying away from publishing further sea ice stories. That might explain its failure to mention sea ice thickening in the Antarctica. According to the Agence France-Presse (October 31, 2001), “Global warming might be a popular worry but scientists on Antarcticas coast this southern summer are recording some of the thickest sea ice ever seen.”

“To my knowledge this is the greatest summer sea ice extent thats ever been recorded in McMurdo Sound,” said Michael Cameron a seal expert working from New Zealands Scott Base. “Everybodys guess is that its due to this giant iceberg off of Cape Bird blocking the swells that would normally break up any sea ice in the area.” The sea ice near McMurdo Sound was 40 percent thicker than normal last year, and this year its even thicker.

Of course, if the New York Times had reported this, they would have explained that thicker Antarctic sea ice is just the sort of thing one would expect with global warming.

Junk Science in Science

The October 26 issue of Science carried a study that attempts to use data from the Nenana Ice Classic, a betting lottery where participants guess the date and time when the frozen Tanana River, near the town of Nenana southwest of Fairbanks, Alaska, breaks up, to detect global warming.

A tripod connected to a clock mechanism on shore is secured to the ice on the river. When the ice melts the tripod is swept downriver tripping the clock and recording the time. This lottery has occurred every year since 1917, thereby providing a continuous record of ice breakup.

The Science study suggests two mechanisms to explain the ice breakup: thermal effects where the ice melts and dynamic effects where the ice is broken up by mechanical forces upstream. The first would be attributed to temperature, the latter to precipitation.

The study claims that there has been a trend towards earlier breakup that is correlated with a warming trend. But this conclusion is dubious, according to John Daly who maintains the “Still Waiting for Greenhouse” website. A look at the whole Nenana record shows significant cyclical variation ice breakup, but overall there is no trend.

The authors of the study, however, begin their statistical analysis at the year 1949, a very cold year. They also excluded the breakup of 2001, which was very late, later in fact than the breakup in 1917. The trend found in the analysis is entirely dependent on the starting and ending dates chosen.

Moreover, as Daly points out, the authors dismiss the possibility of dynamic effects as the major cause of earlier ice break up and claim that there are no significant precipitation and snowfall trends.

“Thats not how the Alaska Climate Research Center sees it,” writes Daly. “As we can see [from their chart] there has been a significant increase in tital snowfall during the 20th century, the inevitable effect of which would be greater mechanical forces acting upon the river ice from upstream, causing it to break up earlier than would be the case with thermal melt alone.”

  • The city of Marrakesh, Morocco, the site of COP-7 was likely chosen for its considerable charms and pleasant climate. Its interesting to note, however, that since 1924 there has been no warming and perhaps an overall cooling in that city (www.john-daly.com).

  • IPCC Chairman Robert Watson told Kyodo News Service (October 18, 2001) that, “I could envision that the U.S. will sooner or later be part of the international debate on climate because industries in the U.S. will demand it.” Fortunately, Dr. Watsons expertise as a scientific bureaucrat makes his political prophecies as credible as his climatic predictions.

Coal Makes a Comeback in UK; Fuel Cells not Ready for Primetime

Coal Makes a Comeback in UK

British coal consumption for electricity generation is going up sharply, which threatens the Blair government’s voluntary pledge to reduce CO2 emissions by 23% below 1990 levels by the end of the decade. According to an October 25 Reuters story, British coal use shot up 17.4 percent in the first quarter of 2001, compared to a 3.6 percent rise for natural gas. In 2000, coal increased 15 percent over 1999, while gas consumption was up only 0.7 percent.

“Emissions have increased for the second year running, above levels when the government first came into office (1997), and this is largely due to increased coal-burn,” Colin Godfrey, managing director of CLG Energy consultants, told Reuters. The “dash to gas” in the 1990s has been reversed by the steep increases in gas prices. Coal is now cheaper than gas.

Powergen, an electric utility, announced that it was re-opening a 1970s-era 485-megawatt coal-fired plant that it shut down in 1996 and would mothball a 450-megawatt gas-fired plant that opened in 1992. Another utility, Innogy, re-started a 340-megawatt coal-fired plant in August that it had mothballed three years ago. Other utilities are reportedly considering closing newer gas plants in favor of older coal plants.

Coal produces roughly twice as much carbon dioxide as gas for each unit of electricity. As Kate Hampton of Friends of the Earth UK remarked, “If there is a shift from gas towards coal we wont meet emission targets. The government has been betting on gas.”

Fuel Cells not Ready for Primetime

A new study by industrial proponents of fuel cell technology examines the challenges that must be met to make fuel-cell-powered vehicles economically viable and concludes that significant government subsidies will be necessary over many years or even decades. “Bringing Fuel Cells to Market: Scenarios and Challenges with Fuel Alternatives” was prepared by a team of experts led by Bevilacqua Knight, Inc., a consulting firm based in Hayward, California, for the California Fuel Cell Partnership.

According to an article on the study by Matt Nauman in the San Jose Mercury News (October 16, 2001), if fuel-cell vehicles are to become commercially viable, the government must spend millions of dollars to minimize the financial risks for car and oil companies…. Thats because it will take years perhaps decades before anyone makes any money of of fuel-cell vehicles or the infrastructure needed to fuel and service them, the study says.

The California Fuel Cell partnerships study specifically examines what it will take from both a technical and an economic standpoint to reach annual sales of 40,000100,000 fuel-cell vehicles in California, or 2 to 5 percent of the market. They study explains that there is tremendous uncertainty regarding whether or not the fuel cell idea is viable.

While discussing prospects for assembling the energy infrastructure necessary to expand usage of fuel cells to a larger scale, they state, “While this study used assumptions judged by its authors to be plausible, these are not forecasts or expectations but illustrative values that combine to create a result that meets the success criterion.”

Thus, they admit that their predictions suffer from the same problems that plague other forms of economic forecasting: it is simply impossible to predict everything that will go wrong with a given technology or innovation particularly if the government plays a major role in pushing it ahead. The Partnership includes major auto companies, oil companies, state and federal government agencies, and fuel cell technology companies. Their report may be found at www.cafcp.org.

Will Anything Happen in Marrakesh?

by William Yeatman on October 30, 2001

in Kyoto Negotiations, Politics

New episodes of the long-running soap opera known as the Kyoto Protocol are being shot this week and next on location in Marrakesh, Morocco, as the world’s major media reported with varying mixtures of anger and sadness that the series big star the United States was still refusing to appear in any new episodes. The new chairman of the seventh Conference of the Parties (COP-7), Moroccan environment minister Mohamed El Yazghi, warned that the Bush administrations decision to stay on the sidelines and merely observe the negotiations could lead to international isolation of the U.S.

Although outgoing COP chairman Jan Pronk and others claimed last July at COP-6.5 in Bonn that they had finally reached agreement on all unresolved issues, it turns out that agreement still must be reached on the “technical details,” that is, on the actual legal text of the agreement in several key areas. The most important of these are reporting, monitoring, and enforcement.

Negotiators in Bonn agreed in principle to enforce the Protocol by penalizing nations that failed to meet their emissions targets. The penalties would include being banned from international emissions trading and other flexibility mechanisms and reducing the emissions limit in the second compliance period (beginning in 2013) by 1.3 tons for every ton of emissions above a nations target in the first compliance period (2008-2012).

This latter penalty is problematic because no targets have been agreed to for the second compliance period. It seems likely that nations failing to meet their initial targets will simply demand easier targets in the second period. What is meant by “legally-binding commitments” therefore remains a major question.

“Im quite worried that the deeper we get into [the legal text], the more bureaucrats trying to re-engineer it will come to fore,” said Paul Vickers, director of TransAlta Corp.s Carbon Market Initiative. “I must admit, I think it’s going to be slower than everyone thinks on rules” (Greenwire, October 26, 2001).

For example, Russia has demanded greater flexibility. As noted in Greenwire (October 30, 2001), under the Bonn agreement “Russia would be allowed to sell the equivalent of 17 million metric tons of CO2 in greenhouse gas emission reduction credits to other countries each year. Russias credit is based on certain forestry sinks aimed at soaking up CO2, as well as the fact Russias emissions fell in the early 1990s when the economic shrank.” Russia is now requesting that its sink credit by doubled to 34 million metric tons of CO2.

COP-7 continues through Friday, November 9, 2001. For daily updates by Bonner Cohen, of the Lexington Institute, of the COP-7 negotiations see www.earthtimes.org.

Is Greenlands Ice Sheet Thinning?; Sea Ice Expanding in Antarctica

Is Greenlands Ice Sheet Thinning?

A new study in Nature (November 1, 2001) claims to have found significant thinning in the north Greenland ice sheet. The study compared current ice sheet thickness, measured by radar altimetry during 1994 and 1995, with ice sheet measurements from 1954, using “trigonometric leveling.” This entailed positioning a tripod at the midpoint of a 1,200-mile traverse from the east to the west coast of the ice sheet. The elevation of the tripod was then measured from 300 stations along the traverse.

The problem is that the east coast and west coast measurements differed by 11.8 meters, a rather large measurement error. The authors of the Nature study attempted to correct the errors through statistical processes based upon assumptions that may or may not be valid. So the 1954 data point is highly suspect.

The ice sheet was divided into six longitudinal bands, A through F. The authors found that the band A ice stream had thickened, bands B-D experienced no significant change, and that bands E and F had thinned.

Since, as the authors note, the “Greenland ice sheet is still responding to climatic changes that occurred thousands of years ago,” it is important to distinguish between long-term changes in ice dynamics with short-term changes in snow accumulation. They argue that their “41-year interval is long enough to ensure that we are measuring the dynamic response of the ice sheet rather than fluctuations in snow accumulation.”

But given that they are comparing two data points rather than a continuous record, their argument is unconvincing. They also note that, “The only other direct measurement of elevation changes in this area come from a study covering the whole ice sheet for the period 1994-99. It shows slight thickening in bands E and F where we measured significant thinning.” They attribute the thickening to “variations in snow accumulation.”

Sea Ice Expanding in Antarctica

We noted in the last issue that Antarctic sea ice has been thickening substantially for the past two years. Now we notice a scientific study published last spring that indicates that this is a longer-term phenomenon. A study published in the April 15 issue of Geophysical Research Letters finds that sea ice in Antarctica has been increasing rather than decreasing for decades. Satellite microwave imaging data from October 1987 to September 1999 “show an ongoing slight but significant hemispheric increase of 3.7 (0.3) percent in extent and 6.6 (1.5) percent in area.”

The authors also note, “These results suggest that the rather smaller increase of 1.0 (0.5) percent per decade in the Antarctic sea-ice extent and 1.3 (0.6) percent in area detected for the period November 1978-December 1996 is ongoing.”

Scientists Lack Necessary Tools to Predict Climate Change; Greening Earth not Necessarily Due to Warmer Climate

Scientists Lack Necessary Tools to Predict Climate Change

A report in Science (September 7, 2001), looks at the issue of climate prediction by looking at one area of the planet that has experienced significant warming, the Antarctic Peninsula. According to Vaughan, et al., the average temperature increase for all Antarctic stations from 1959 to 1996 was about 1.2 degrees Celsius. Some regions, however, experienced cooling trends, while others experienced warming trends.

The Antarctic Peninsula has experienced a warming trend “considerably larger” than the Antarctic average. The authors argue that, “There is a 99 percent likelihood that the recent warming is exceptional compared with any part of the 500-year period recorded in the longest of these records.”

By analyzing sediment cores the authors found that seven ice shelves, including the Prince Gustav Channel ice shelf that collapsed in 1995, have been lost in the last fifty years in the Antarctic Peninsula. They also found, however, that between 6000 and 1900 years ago the Prince Gustav “ice shelf was absent and climate was as warm as it has been recently.”

“The recent rapid regional warming in the Antarctic Peninsula is thus exceptional over several centuries and probably unmatched for 1900 years,” according to the authors. “It may be tempting to cite anthropogenic greenhouse gases as the culprit, but to do so without offering a mechanism is superficial.” Of course, recent climatic conditions in the area are not exceptional for the last 6000 years.

The authors offer three possible explanations for the warming in the Antarctic Peninsula, but warn that, “Because we cannot distinguish between these widely differing mechanisms, we have no basis for predicting future changes, even if we accept that the recent warming is exceptional.” They conclude, “This suggests that we do not yet have tools to predict potentially socially significant regional climate changes in the next 100 years.”

Greening Earth not Necessarily Due to Warmer Climate

We reported in the September 5 issue about a study that was to be published in the Journal of Geophysical Research-Atmospheres (September 16, 2001). The study argued, “that warmer temperatures and elevated levels of carbon dioxide have led to a greening of the northern hemisphere.”

It seems, however, that there are some problems with the study. According to John Daly (Still Waiting for Greenhouse, www.john-daly.com), the studys claim that warmer temperatures are causing a greener greenhouse is wrong. Thus the increases in vegetation must be due solely to higher levels of CO2, as hundreds of agricultural studies have shown.

A press release from the American Geophysical Union explains that, “Researchers using satellite data have confirmed that plant life above 40 degrees north latitude (New York, Madrid, Ankara, Beijing) has been growing more vigorously since 1981 due to rising temperatures and buildup of greenhouse gases, and Eurasia seems to be greening more than North America, as existing vegetation is more lush for longer periods of time” (www.enn.com).

The correlation between temperature and greening above 40 degrees latitude is fairly weak, according to Daly. From the early-to-mid 1980s there was significant greening even though temperatures were hardly changing. Other years also show significant greening in cooler years.

More importantly, however, when discussing the amount of greening the study includes the area above 30 degrees latitude, which includes the southern United States. But, the area between 30 and 40 degrees latitude is not included when the researchers correlate temperature and plant life. Since the southern U.S. has greened significantly while temperatures have trended downward, including that data would have made the correlation between temperature and plant life disappear altogether.

Daly argues that the CO2 fertilizer effect is the only remaining explanation for the greening of the planet.

Climate Change Policies Add to Economic Hard Times

by William Yeatman on October 2, 2001

Over the last year, industrial gas prices in Great Britain have risen by more than 50 percent, an increase that was kicked off with the governments new climate change levy that increased prices by 7 percent. Rising world prices contributed the remainder of the increase. The climate change levy has also increased the price of coal by 13 percent and electricity by 8 percent (Daily Telegraph, September 28, 2001).

Many businesses are feeling the impacts of the new tax. Carpetmaker Stoddard International has seen its operating profit fall 35 percent in the last half year, which chief executive Alan Lawson attributes in part to the climate change levy. The companys energy costs rose by 250,000 pounds sterling, some as a result of the levy. “The principle is fine but the actual levying of it is penal, especially at a time when we are facing currency costs and threats of cheaper imports from countries which dont have the climate change levy,” said Lawson (The Herald (Glasgow), September 28, 2001).

The Engineering Employers Federation in Great Britain conducted a survey of 550 engineering firms and found that the costs of the climate change levy would exceed 100 million pounds sterling. “Our figures prove that the Government was wrong when saying the levy would not impact on competitiveness because it is imposing an ever greater burden on manufacturing at a time when it is already in recession,” said Martin Temple, EEFs director general (Belfast Telegraph, September 24, 2001).

EU Bows to Industry Pressure; EU to Propose Aviation Fuel Tax

EU Bows to Industry Pressure

The European Union has been devising an emissions trading scheme to trade greenhouse gas permits, that is scheduled to take effect in 2005. According to Reuters (October 2, 2001), “The EU executive originally aimed to propose the regulations in July but was persuaded to redraft them in a more business-friendly form after intense lobbying from industry.”

Firms within the EU have demanded the changes because they fear that the plan would put them at a competitive disadvantage with U.S. firms. “The latest draft bows to several industry demands by halving the proposed fines, allowing the Commission to exempt certain sectors temporarily and enabling member states to give firms extra emission credits in special market conditions.”

Fines for noncompliance were reduced from 200 euros to 100 euros per excess ton of CO2 emitted. If permit prices go too high, then governments can issue extra permits. Governments can also temporarily exempt certain sectors during the first three years of the program if they can demonstrate that they can reduce the same amount of emission by other means.

The ability of governments to issue additional permits is very problematic and is likely to short circuit the trading that would take place otherwise. Increasing the supply of permits not only defeats the cap, but it also decreases the price of existing permits, thereby harming the firms holding them.

EU to Propose Aviation Fuel Tax

The European Union is pushing for a tax on aviation fuel for international flights at a meeting of the International Civil Aviation Organization currently underway in Montreal. Under a long-standing international agreement, aviation fuel for international flights is exempt from taxation. Environmentalists claim that this is a major subsidy to the airline industry.

The EU says that if an agreement cannot be reached it may and unilaterally impose a tax on internal EU flights or impose a tax on airfreight (ABC News, September 15, 2001).

Artful Bias or Outright Deception?; No Rise in New England Hurricanes

 Artful Bias or Outright Deception?

The IPCCs assessment reports and especially its summaries for policymakers have been criticized from many quarters and have been shown to contain many errors and weaknesses. One of the most recent criticisms, and perhaps the most devastating, is the one authored by Dr. David Wojick, president of Climatechangedebate.org, who has a Ph.D. in mathematical logic and philosophy of science.

In the report, The UN IPCCs Artful Bias, Wojick analyzes the Summary for Policymakers (SPM) for Working Group I, which deals with the science, of the IPCCs Third Assessment Report. According to Wojick, the SPM “is an artfully constructed presentation of just the science that supports the fear of human induced climate change. It is as one sided as a legal brief, which it resembles.” Wojick goes on to argue, “A line by line analysis of the SPM reveals that all of the science that cuts against the theory of human interference with climate has been systematically omitted.”

The first problem that Wojick presents is that the IPCC ignores the errors in the surface temperature data. The SPM claims, “The global average surface temperature has increased over the 20th century by about 0.6 degrees C.” The certainty expressed in this statement, says Wojick, is unwarranted.

Despite the many problems with the surface temperature record, the IPCC only briefly mentions the urban heat island effect and claims that all errors have been taken into account, without explanation. But as Wojick explains, “There is no way to correct for most measurement errors, including the urban heat island effect. The magnitude of these errors, which may be quite large, is simply unknown. The supposed corrections that have been made to date are merely guesswork.”

Moreover, the temperature data that we have is not a random sample of the Earths surface, but a “convenience sample,” or data that is the most convenient. The IPCCs “reference to data gaps,” says Wojick, “suggests that sometimes a station did not record, or the data is bad, not that there is in actuality no data for most of the earth, most of the time. So the fact that we merely have a convenience sample is either omitted, or cleverly disguised.”

The importance of this point is that the IPCC has calculated its confidence levels as if it had a random sample. Given that the sample is not random, the margin of error in the data is much larger than suggested by the IPCC.

Other problems with the IPCCs SPM is how it glosses over the “profound contradiction” between the satellite temperature record and the surface record, the huge uncertainties with regard to aerosols, the omission of natural sources of greenhouse gas emissions, and the inadequate treatment of the chaotic nature of the Earths climate. The full critique can be found at www.john-daly.com.

No Rise in New England Hurricanes

Another peer-reviewed scientific study of hurricanes has failed to find a trend in hurricane activity in the United States, let alone a link between hurricane activity and global warming. The study, published in Ecological Monographs (71: 2001), looks at hurricane data from 1620-1997.

What the authors found was that, “there was no clear century-scale trend in the number of major hurricanes.” They did find that there were more lower intensity hurricanes reported in the 19th and 20th centuries than there were in the 17th and 18th centuries. But the authors attribute the difference to “improvements in meteorological observations and records since the early 19th century.” Also, the data from the last 200 years show that there were five of the strongest category hurricanes reported in the cooler 19th century and only one reported during the 20th century.

Environmentalists Defeated on Two Fronts; New Jersey Initiates Voluntary Cap and Trade Program

Environmentalists Defeated on Two Fronts

Local residents of a small rural community in Great Britain have succeeded in defeating the construction of a biomass power plant. The proposed wood-fueled power plant, costing 10 million pounds sterling, was turned down by the North Wilshire District Council following an appeal by Ambient Energy, the company behind the plan.

Ambient Energy argued that the power plant would produce enough energy for 10,000 homes without creating greenhouse gas emissions. But a group organized by Cricklade residents, known as BLOT (Biomass Lumbered on our Town) argued that the plant, that would include two 80 foot chimney stacks and two 50 foot burners would be an eyesore, and create an increase of traffic of heavy trucks. Rodney Baker, the planning inspector said, “The scheme would have a noticeable and harmful effect on the character and amenity of the landscape” (Western Daily Press, September 17, 2001).

Residents of Eugene, Oregon have voted by a greater than 2 to 1 margin to reopen a downtown pedestrian mall to vehicle traffic (Associated Press, September 19, 2001). The margin of the vote is surprising in that Eugene, home of the University of Oregon, is known throughout the Northwest as the Peoples Republic of Eugene for its leftist politics.

The pedestrian mall was the centerpiece of a 1971 urban renewal plan that was supposed to “bring new life to the citys center, providing shoppers with a progressive, car-free city core geared to pedestrian traffic” (The Oregonian, September 17, 2001). The anti-car plan backfired, however, as businesses fled to the suburbs due to decreased sales.

“If you do it and it doesnt work, then you change it. And they never changed it,” said Bill Combs, Jr., who moved his shoe store from the downtown mall in 1990. “No traffic. No cars. That was the problem. They essentially killed retail downtown.”

New Jersey Initiates Voluntary Cap and Trade Program

The state of New Jersey has unveiled a voluntary cap and trade program for carbon dioxide emissions. According to John J. Fialka of The Wall Street Journal, the program creates incentives for companies, government agencies, and individual consumers to trade credits for emissions.

The plan is the brainchild of former Governor Christine Todd Whitman, who led a task force to calculate the expected costs of rising sea levels in 1994. This effort led current New Jersey state environmental minister Robert Shinn, Jr. to conclude that reducing greenhouse gas emissions would be the most cost-effective approach to abating the rise in sea levels in 1997.

After making this announcement, Shinn conducted an audit of existing voluntary greenhouse gas reduction programs in New Jersey and concluded that the state could reduce its emissions to 3.5 percent below 1990 levels by 2005. This led him to demand the states seven largest utilities to develop a standardized measurement system for their emissions. In addition, he persuaded nine major companies with headquarters in the state to sign a “covenant of sustainability” under which they promise to monitor and reduce emissions.

The “carrot” of the program is funded through the “societal benefit charge” imposed on electricity users through the states electricity restructuring. This fund, used to compensate individuals and companies that participate in the trading and reduction program or install energy-efficiency or renewable energy equipment, is expected to generate more than $358 million over the next three years.

New Jersey joins Massachusetts as the only states currently regulating carbon dioxide emissions. New York, New Hampshire, North Carolina, Florida, and Illinois are considering similar programs (Wall Street Journal, September 11, 2001).

A Greener Planet; Warming and Cooling in Alaska

A Greener Planet

A new study slated to appear in the September 16 issue of the Journal of Geophysical Research-Atmospheres has found that warmer temperatures and elevated levels of carbon dioxide have led to a greening of the northern hemisphere. Contrary to conventional wisdom, which portrays global warming as an unmitigated disaster, this new study confirms what numerous other studies have found; that many benefits may result from a warmer planet.

A press release from the American Geophysical Union explains that, “Researchers using satellite data have confirmed that plant life above 40 degrees north latitude (New York, Madrid, Ankara, Beijing) has been growing more vigorously since 1981 due to rising temperatures and buildup of greenhouse gases, and Eurasia seems to be greening more than North America, as existing vegetation is more lush for longer periods of time” (www.enn.com).

One of the researchers, Ranga Myneni, of Boston University, “suggested that these results are indicative of a greener greenhouse. This is an important finding because of possible implications to the global carbon cycle, he said. Further, Myneni said, under the Kyoto Protocol, most of the developed countries in the north can use certain vegetation carbon sinks to meet their greenhouse gas emissions reduction commitments. If the northern forests are greening they may already be absorbing carbon dioxide. Myneni said, As to how much and for how long, that needs more research.”

Warming and Cooling in Alaska

Global warming alarmists have repeatedly pointed to warmer temperatures in Alaska as a major sign that significant global warming has already arrived. Recent research, however, has found that Alaska has undergone similar periods of warming before man began to burn fossil fuels.

In a study in the August 21 issue of the Proceedings of the National Academy of Sciences, Dr. Feng Sheng Hu, a professor of plant biology and geology at the University if Illinois, and his co-authors, constructed a continuous 2,000-year temperature record of the area by analyzing sediment samples from Farewell Lake, near the northwest foothills of the Alaska Range. What they found was that there were two periods of warm climatic conditions that occurred in A.D. 0-300 and 850-1200, which were also characterized by dryer than normal conditions.

An article about the study noted that Dr. Hu and postdoctoral associate Will Turner did a follow up study that found that forest fires were more abundant during the Little Ice Age than during warming periods, contradicting global warming predictions (www.news.uiuc.edu/).

Etc.

  • The Los Angeles Times (September 1, 2001) reports that the San Fernando Valley is experiencing its coolest summer since 1987. According to Tim McClung, a Weather Service meteorologist, “The average temperature in downtown Los Angeles in July was 71 degrees, 3.9 degrees below the normal average of 74.9. The average August was 72 degrees, 4 degrees below the average of 76.”
