Contrary to the author's opinion in ``Radio Free Asia: Costly, Counterproductive,'' Sept. 13, a well-balanced Radio Free Asia would be a bargain at $10 million a year. During the ``nonexistent'' Tiananmen incident, I was at a university in Nanjing. We could have used a truthful source of information in those terrible days after the June 4, 1989, incident. My greatest pain came with the realization that the majority of Chinese would never know the truth. But as China grows, the government will not welcome the infringement on its sovereignty imposed by another radio broadcast. Competing ``truths'' are not in the government's best interest.

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.
