It could take a decade or more of climatic crisis to generate a widespread sense of urgency about changing lifestyles. Politicians may ultimately be forced to wait. The planet, unfortunately, will...
...Kyoto treaty is based upon the assumption that the carbon gases created by the burning of fossil fuels significantly contribute to global warming through the "greenhouse effect" - a layer of vapor and gases that trap the sun's heat in our atmosphere. And that assumption is based on solid science, according to the consensus among mainstream scientists, notwithstanding the protestations of Governor Bush, the petrochemical industry and a minority of scientists...
Mass burnings cause the emission of many chemicals that destroy ozone. Large quantities of methyl bromide and other halogen-containing chemicals are pushed skyward in biomass fires. Such fires could be the source of most of the bromide getting to the ozone layer and destroying it. Large quantities of sulfur dioxide are also emitted that can increase acid-rain fallout. The U.N. needs a program to discourage deliberate biomass burning. JAMES A. SINGMASTER III Fremont, Calif...
