Clarifying Global Warming
RECEIVED Mon., Oct. 27, 2003
In his article published Oct. 3 in the Chronicle, Jim Hightower ["The Hightower Report"] discusses global warming and states, "At issue is the thin layer of ozone that encapsulates our globe."
Global warming is indeed an important issue, but Mr. Hightower is apparently confused as to the suspected cause of this phenomenon.
It is the buildup of greenhouse gases (mainly carbon dioxide) in our atmosphere that is suspected of causing global warming, and not stratospheric ozone depletion (which is/was largely due to CFC emissions).
Both stratospheric ozone depletion and global warming are serious environmental issues; however, they are different problems with largely separate causes.
Mr. Hightower, and the public in general, should do more to educate themselves regarding each of these problems.
