UK OZONE REPORT

Item #d91sep114

A new UK ozone report shows that stratospheric ozone has declined by 8 percent in the past decade in the middle latitudes of the Northern Hemisphere, about twice as fast as had been anticipated. An independent U.S. study released in April (Global Climate Change Digest, News, May 1991) showed a loss of about 5 percent per decade in the middle latitudes, although that analysis was based on winter data and is not directly comparable to the U.K. study which used spring data. (See Reports, this Global Climate Change Digest issue--Sep. 1991; New Scientist, p. 15, July 27, 1991; Nature, p. 271, July 25.)
