Satellite Data Contradicts Gov. Bush, Shows Cooling Trend
After a hot 1998 due to El Nio, 1999 seems to be returning global temperatures, as measured by satellites, to their previous downward trend. According to Dr. John Christy, a professor of atmospheric science at the University of Alabamas Earth System Science Laboratory, the advent of La Nia, the cool phase of El Nio, is quite obvious in the record. “Compared to seasonal norms, April 1998 was the hottest month in more than 20 years,” Christy said. “But this April it was quite cool in the tropics.”
Christy also points out that from April 1998 to March 1999 the global average temperature dropped almost nine-tenths of a degree Celsius (about 1.6 degrees Fahrenheit). The Northern Hemisphere in April 1999 was slightly warmer than the 20-year average while the Southern Hemisphere was slightly cooler. Overall, April was 0.01 degrees Celsius cooler than normal.
Trees Do Better With More CO2
Hundreds of studies and experiments have confirmed that the earths plant life flourishes in a carbon dioxide rich environment. The latest study, appearing in Science (May 14, 1999), confirms these findings. In the latest experiment researchers installed a gas delivery system in a 13-year-old loblolly pine plantation. The system increases CO2 concentrations on 30-meter diameter plots within the continuous forest.
The researchers argue that currently “trees that use the C3 mechanism of photosynthesis are carbon-limited at the current atmospheric CO2 concentrations,” and that “the stimulation of photosynthesis by elevated CO2 may increase the capacity of forests to store carbon in wood and soil organic matter.”
The researchers found during the two years of the experiment that the diameters of the trees exposed to concentrations of CO2 double ambient levels, increased by about 26 percent relative to the control trees. CO2 enrichment also increased litterfall and fine root increment. “Such an increase in forest net primary production globally would fix about 50 percent of the anthropogenic carbon dioxide projected to be released into the atmosphere on the year 2050.”
New Book Looks at Extreme Weather and Civilization
We have argued in these pages that the ability to adapt to changes in climate is the greatest protection against the dangers of catastrophic events. This view is generally confirmed in a new book titled Floods, Famines and Emperors: El Nio and the Fate of Civilizations. The author, Brian Fagan, anthropology professor at the University of California at Santa Barbara, looks at the havoc El Nio has wreaked upon civilizations over thousands of years, and claims that it contributed to the downfall of civilizations from Egypts Old Kingdom to the classic Maya culture on the American continent.
An important message of the book, according to reviewer David Lashkin, is that “catastrophically fluctuating weather patterns are a natural characteristic of Earths atmosphere, and civilizations unable to adapt to these violent meteorological swings have been destroyed in the past and will be destroyed in the future.” Two main determinants of whether a civilization survives climatic change is “carrying capacity” and “the flexibility of their social structures and customs.” Rigid, “top-heavy” societies are more vulnerable to catastrophe than dynamic societies (The Washington Post, May 20, 1999).

- The U.S. delegation to the International Whaling Convention called global warming “the greatest threat” to whales. The delegation is calling for research into the effects of global warming on whales’ food supplies. It has also warned that global warming could cause melting of the polar ice caps, bringing more ships into contact with whales and interfering with their habitats.
- So-called renewable energy seems to be getting less popular as the energy of choice among certain factions within the Green community. Recently the National Trust in England has “pledged to fight green energy schemes such as wind farms where it judges them unacceptable intrusions into Britains remaining wild places,” according to The Guardian (May 20, 1999).
- Apparently Maurice Strong, known for his gentlemanly manner, completely lost it when he learned that a fellow oil man Bob Peterson, head of Imperial Oil, said that compliance with the Kyoto Protocol would devastate Canadas economy. Strong, a former energy CEO himself, and currently the United Nations special adviser on the environment accused Peterson of being “behind the times” and a “dinosaur.”
He also said that “Mr. Peterson had his counterparts in earlier days when the Petersons of that day were against abolishing child labour, they were against sanitation, they were against abolishing slavery.” The National Post (May 21, 1999) commented that “Mr. Stongs intemperate outburst may be tantamount to an admission that his perverse crusade to save the planet by destroying the global economy is grinding to a halt.”
