Damaging a fragile ecosystem

The article ``Scientists Question Global Warming Theory,'' Sept. 14, insinuates that the scientific community is now discounting the possibility that an increase in atmospheric greenhouse gas concentrations might lead to global warming. However, the Intergovernmental Panel on Climate Change, (140 scientists and 230 reviewers) in the Sept. 24 edition of Science News, concludes that the effects of variations in solar radiation and increased sulfur emissions were too weak to counter the warming influence of greenhouse gases. There is overwhelming evidence that emissions from fossil-fuel combustion are doing considerable damage to fragile ecosystems. Therefore, a simultaneous reduction in CO2 and sulfur emissions is a long-range imperative. Mike Genthner, Blacksburg, Va.
