IN BRIEF
Sign of Global Warming Found in Atmosphere
From Times Staff and Wire Reports
Researchers at Lawrence Livermore National Laboratory cited new evidence
that humans are changing the climate. The tropopause, the zone separating
the turbulent lower section of the atmosphere from the more stable
stratosphere, has heightened over the last two decades.
In a study published Friday in the Journal of Geophysical Research,
scientists said the cause was warming of the troposphere by greenhouse
gases and cooling of the stratosphere caused by depletion of ozone.
