CORVALLIS, ORE. A GROWING body of scientific research now indicates that acid rain is developing into a national problem, not simply a matter of concern to New England and New […]

LEAD: The buildup of carbon dioxide and other gases in the atmosphere, which might warm the earth's climate to dangerous levels, could be significantly reduced if governments took concerted action, […]

ATMOSPHERIC scientists are struggling to explain one of the strangest mysteries ever to confront them: a widening and potentially dangerous hole in the ozone layer over the South Pole. Putting […]

LEAD: The atmosphere's protective shield of ozone ebbed rapidly from 1979 through 1986, not just over Antarctica, where the depletion has been sharpest, but over nearly the whole globe, researchers […]

LEAD: Acid rain appears to pose a long-term threat to forests, but ozone and natural causes of stress are also implicated in forest decline and may be more harmful to […]

LEAD: Air partly depleted of ozone appears to be transported from Antarctica to New Zealand and southern Australia by air currents in the atmosphere, scientists reported last week. Air partly […]

LEAD: ENVIRONMENTAL scientists in recent months have been faced with a seeming paradox: one group of researchers has determined that the ozone shield, which screens out harmful ultraviolet radiation, is […]
