meetings coincide: Two meetings of international interest on
global warming science and policy have been scheduled during the
first week of April 1994. Although their titles are similar, the
San Francisco meeting stresses the communication of scientific
progress to policy makers to promote national and international
planning. The Phoenix meeting emphasizes more technical topics
such as carbon cycling, model evaluation and emission control.
Interested individuals should obtain the detailed lists of topics
and symposia, and may wish to spend time at both.
research in the U.S. is uncoordinated and has a limited
impact on national policy, according to a report by a National
Research Council panel, which recommends solutions. See Reports,
and article in Chem. Eng. News, p. 4, May 17 1993.
A 21st Century Earth Award goes to Daniel Kammen at
Harvard University's Center for Global Environmental Change, for
his role in projects intended to develop and promote improved
biomass stoves, solar ovens and other small-scale renewable
technologies in developing countries. These can cut fossil fuel
use by 50 percent or more, and improved stoves reduce indoor air
pollution. The annual award competition is conducted by several
Japanese firms in conjunction with the U.N. and other
institutions. (Contact Secretariat, 21st-Century Earth Award,
3-1-4-1004, Tsukjii, Chuo-ku, Tokyo 104, Japan; fax:
Ozone Backlash," G. Taubes, Science, pp. 1580-1583,
June 11. Similar in vein to other recent articles (Global
Climate Change Digest, p. 96, June), this discusses how ozone
researchers have paradoxically been subjected to pseudoscientific
public criticism of their theories and motives, while the
evidence for the role of CFCs in ozone depletion has grown
stronger. Includes an analysis of the February 1992 press
conference in which NASA scientists warned of the potential of
severe ozone loss in the Northern Hemisphere within the next
decade, then were taken to task by some in the press when it did
not materialize that year.
"IPCC Sets Topics to Be Covered in 1995 Report," Global
Environ. Change Rep., p. 5, July 22. Summarizes plans for the
next scientific assessment by the Intergovernmental Panel on
Climate Change, and other activities of the panel related to the
"Skepticism Rises About Meeting [Japan's] Carbon Dioxide
Emission Level Goals for 2000," Intl. Environ. Rptr.,
p. 446, June 16. Government officials are beginning to doubt
whether Japan can stabilize CO2 emissions at 1990
levels by the year 2000. A tougher energy conservation policy or
some form of tax may be necessary.
following feature news/analysis articles have appeared in Global
Environ. Change Rep. on pp. 1-3 of the 1993 issues indicated:
"Carbon Offsetting Goes Commercial," July 9. A new
firm, Global Warming Alternatives of El Cerrito, California, is
selling shares in a wide range of carbon offset projects (such as
forestry and energy conservation) to businesses, governments and
"Clean Coal Technology for Developing Countries: Can the
Barriers Be Broken?" June 11. Over half the world's coal
supplies are located in developing countries; suitable technology
could lead to a 30% reduction in CO2 emissions when
this fuel is burned.
"Support Grows for a CO2 Protocol-But
When?" Feb. 12. Assimilates the views of several individuals
in the U.S. and abroad that reflect the international enthusiasm
for tackling specific agreements on CO2 control within
the Framework Convention on Climate Change.
"Criteria for International Offset Projects: A Look at
the Issues," Jan. 29. Examines the practical difficulties of
joint implementation, whereby countries can claim emission
reduction credits for projects carried out elsewhere.
