EARTH SUMMIT PREPARATIONS
Participants at a late October 1991
meeting of the Intergovernmental Panel on Climate Change (IPCC) agreed that
control of greenhouse gases should be the emphasis at the June 1992 U.N.
Conference on Environment and Development (UNCED). (Intl. Environ. Rptr.,
pp. 603-604, Nov. 6, 1991.)
The International Council of Scientific Unions (ICSU) organized a conference
in Vienna in late November 1991 to provide interdisciplinary input to the
preparations for UNCED. At the opening of An Agenda of Science for
Environment and Development into the 21st Century, Bert Bolin, chairman of
the IPCC, admonished politicians who are waiting for scientific certainty before
taking action on climate change (New Scientist, p. 13, Nov. 30, 1991).
The conference closed with a call for a new relationship between scientists and
policy makers, and committed the ICSU to a review of science's relationship with
U.N. agencies, industry, environmental groups and the media (ibid., p.
17, Dec. 7).
A dangerous polarization emerging between the nations of the rich North and
those of the poor South in the negotiating sessions leading up to UNCED is the
subject of an article in New Scientist, pp. 20-21, Nov. 23, 1991.
