Nature quoted scientists at NASA's Atmospheric Sciences Division in Hampton, Virginia, as reporting that forest fires-previously thought to be a major source of nitrous oxide-actually produce only about seven percent of the amount in the atmosphere. The importance of the source of nitrous oxide relates to its action in the destruction of Earth's ozone layer. (W Post, Feb 25/91)
Bill Moyers, a member of a national panel of experts involved in Project Censored, a compendium of the most underreported stories of 1990, dealt with NASA and the ozone. Soviet scientists first raised environmental questions about the solid rocket fuel used by the Space Shuttles. They said it left 250 tons of hydrochloric acid eating up the ozone layer after every launch. The Earth Island Journal and the San Francisco Chronicle reported the story. On the program, environmental activist Helen Caldicott spoke of chlorine molecules that chomp up ozone molecules. (P Inq, Feb 25/91)
