A Guide to Information on Greenhouse Gases and Ozone Depletion
Published July 1988 through June 1999
FROM VOLUME 3, NUMBER 8, AUGUST 1990
"Controlling the Greenhouse," K. Mellanby, New Sci., p.
71, June 23, 1990.
Commentary by the founder-editor of the journal Environmental Pollution.
Believes the only practical program to prepare for possible global warming would
be for the advanced countries to phase out fossil fuels and rely more on nuclear
power while developing renewable sources of energy.
"The Race to Heal the Ozone Hole," H. Steven, A. Lindley, ibid.,
48-51, June 16, 1990.
The phasing out of CFCs has meant a period of rapid change for the chemical,
refrigeration and air conditioning industries. Discusses the problems of
telescoping decades of experience and testing into a few years to replace CFCs.
One solution HFA-134a, developed after only three years work, is gaining
acceptance as an efficient replacement in domestic refrigeration and air
"Clean Cars," F. Lyman, Technol. Rev., 22-23, May/June
Summarizes the relative impact of methanol as an alternate fuel. Although it
has no particulate emissions, reduced CO2 emissions, more horsepower and more
acceleration, methanol does not lower CO and NOx emissions and increases
formaldehyde emissions. If made from coal, methanol can double carbon-dioxide
"Mr. Bush and His Billion Trees," N. Davis, Amer. For.,
17-20, May/June 1990.
The government's tree-planting initiative along with the continued support
of volunteer groups has the potential of becoming a legacy for generations.
Outlines briefly the proposed America the Beautiful project, followed by some
Congressional comments and reactions.
"A Cool Solution to Global Warming," D. Olivier, New Sci.,
42-45, May 12, 1990.
Due to the high premium they must pay from little competition and no
legislation that encourages changes to new refrigerators and freezers, European
consumers cannot reap the economic benefits from energy-efficient appliances.
Government intervention will be essential to encourage these market forces.
"Too Much Life on Earth?" P. Harrison, ibid., 28-29, May
Slowing population growth will reduce damage to the environment in the long
term, but in the shorter term other measures will have a greater impact, such as
reducing consumption, shifting to sustainable technologies, halting
deforestation, attacking poverty and inequality, and introducing land reform. To
reduce population growth, governments must focus their attention on enhancing
the rights, education and health of women and children.
"Still Working on the Ozone Hole: Beyond the Montreal Protocol,"
A. Makhijani, A. Bickel, A. Makhijani, Technol. Rev., 53-59, May/June
The Montreal agreement has spurred cuts in the use of ozone-depleting CFCs.
But signatories must soon decide whether to include more compounds (e.g. methyl
chloroform and carbon tetrachloride) and how to increase Third World
participation. Poor nations will not participate in CFC cutbacks unless rich
nations help them develop and use technologies that do not rely on
"Slowing Global Warming," C. Flavin, Amer. For., 37-44,
Coping effectively with global warming requires a strong commitment to a
global policy of greater energy efficiency and renewable energy sources.
Excerpted from State of the World 1990, this article outlines in
extensive tabular format the information necessary to develop a realistic global
carbon budget. Among the tables included: "Climate Policies Enacted and
Proposed, November 1989," "Costs of Avoiding Carbon Emissions
Associated with Alternatives to Fossil Fuels, 1989," and "Proposed
Emission Goals, Sample Countries."
"Filling Up in the Future," N. Lenssen, J.E. Young, World
Watch, 18-26, May/June 1990.
Calls for a united approach to reduce both air pollution and
climate-altering emissions. Significant declines in greenhouse emissions from
transportation will only be possible if nonfossil-fuel alternatives replace
petroleum, fuel efficiency climbs rapidly, and dependence on private automobiles
"Hot Air on Global Warming," M.G. Renner, ibid., 35-37,
Laments the precipitous decline since 1980 in research and development on
efficiency and renewables among members of the International Energy Agency,
which is composed of 20 western industrialized countries that consume 45% of the
world's fossil fuels. If spending had been maintained at the level of the early
1980s, the world would be a big step ahead in the struggle against climatic
"CFCs--No Easy Solutions," S. Derra, R&D Mag.,
56-66, May 1990.
Promising chemicals and technologies are on the horizon, such as the use of
fluoroethers and technologies like compressed helium refrigeration, but these
technologies either require changing infrastructures or cannot be developed in
time to meet the Montreal Protocol deadline. Industry is gambling hundreds of
millions of dollars in building new facilities to meet these deadlines with
acceptable interim CFC replacements, while still developing what could prove to
be better compounds.
"New Push for Energy Efficiency," L. Lamarre, C. Gellings, T.
Yau, EPRI J., 4-17, Apr./May 1990.
This feature article explains how consumers in the residential, commercial
and industrial sectors have been slow to adopt efficient end-use energy
technologies. Regulatory agencies are now looking at ways to encourage utility
investments in promoting efficient electricity-based technologies. Lists further
reading that encourages these strategies.
"Measurement of Nitrous Oxide Emissions," A. Kokkinos, ibid.,
Previously reported high levels of N2O emissions from fossil fuel combustion
are incorrect because of systematic errors in the measuring technique used.
Ongoing research is building a body of accurate N2O emission measurements and
investigating the formation of this gas, considered a significant contributor to
the greenhouse effect.
