- The U.S. Department of Energy's Office of Fossil Energy and Office
of Science are jointly carrying out research on the capture and storage
of carbon in terrestrial ecosystems. The goal of the program, which
is managed by the National Energy Technology Laboratory, is to provide
economically competitive and environmentally safe options for offsetting
the projected growth in carbon dioxide emissions.
Climate Change Impacts for the United
States: The Potential Consequences of Climate Variability and Change
- The National Assessment of the Potential Consequences of Climate Variability
and Change is a landmark in the major ongoing effort to understand what
climate change means for the United States. The Assessment was called
for by a 1990 law, and has been conducted under the US Global Change
Research Program in response to a request from the President’s Science
Advisor. This site contains the final version of the report of the National
Assessment Synthesis Team, which was a federal advisory committee made
up of experts drawn from government, universities, industry, and non-governmental
organizations. The report is provided in two parts: (1) an Overview
report, and (2) a Foundation report that provides additional detail
and full references. Information
about obtaining printed copies of the report is available from Cambridge

Climate Variability and Change in the Southwest: Impacts, Information
Needs, and Issues for Policymaking (773Kb PDF file)
- At the request of the U.S. Department of the Interior and the U.S.
Global Change Research Program (USGCRP), the Udall Center for Studies
in Public Policy and other units at The University of Arizona organized
and hosted the Southwest Regional Climate Change Symposium and Workshop
in Tucson, Arizona, on September 3-5, 1997. The intent of the symposium
and workshop was to bring together important stakeholders--representatives
from the private sector, government agencies, educational institutions,
and interested citizens--to determine the state-of-knowledge, information
and research needs, and possible policy strategies related to the impacts
of and responses to climate variability and change in the Southwest.
- Hearing Before
the U.S. Senate Committee on Commerce, Science, and Transportation (21
- This hearing follows two others--one examining the science behind
global warming as a means of defining the issue of climate change (17
May 2000) and the other addressing the National Assessment Report,
Climate Change Impacts on the United States (18
July 2000). This current hearing examines a few of the many solutions
or approaches to reducing greenhouse gas emissions.
- CONSEQUENCES: The Nature
and Implications of Environmental Change
- Volume 5, issue 2 of Consequences features three review articles on
El Niño-Southern Oscillation (ENSO) phenomenon and its global impacts.
Steven Zebiak writes about "El Niño and the Science of Climate
Prediction"; Chester Ropelewski's article is "The Great El
Niño of of 1997 and 1998: Impacts on Precipitation and Temperature";
and E. S. Sarachik brings us "The Application of Climate Information".
- Hearing Before
the U.S. Senate Committee on Commerce, Science, and Transportation (18
- A national assessment of the potential impacts of climate change was
called for in the 1990 legislation that established the US Global Change
Research Program (USGCRP). To respond to this charge, the USGCRP began
the National Assessment of the Potential Consequences of Climate Variability
and Change in 1997 by initiating a series of 20 workshops around the
country to identify the critical interfaces between climate change,
the environment, and society. A
draft report was released for public review on June 12. The July
18th hearing was to hear testimony on the draft report.
- Report of the International
Workshop on Population-Poverty-Environment Linkages
- In the 1990s, a series of global conferences succeeded in raising
awareness of the challenges facing the world due to interactive linkages
among population, increasing poverty and environmental degradation.
These conferences – the United Nations Conference on Environment and
Development (UNCED), the International Conference on Population and
Development (ICPD), the Fourth World Conference on Women, and the World
Summit for Social Development (Social Summit) – arrived at consensus
on the actions required to bring about environmentally sustainable and
equitable development. Since those conferences, the international community
has continued to assess progress and to improve the translation of the
general consensus guidelines into national and local action programs.
- Hearing Before
the U.S. Senate Committee on Commerce, Science, and Transportation (17
- The hearing on the Science of Global Warming focused on the scientific
facts behind global climate change. Witnesses consisted of several experts
on climate and atmospheric science involved with the administration,
federal agencies, and academic and international research institutions.
While the expert testimony covered several different themes within climate
change science, a few key issues were stressed by all of the witnesses
as conventional wisdom accepted by an overwhelming majority of the scientific

of the United Nations Framework Convention on Climate Change (UNFCCC).

- Climate Change: Mitigation,
Vulnerability, and Adaptation in Developing and Transition Countries
- This report provides an overview of the work conducted by developing
and transition countries participating in the U.S. Country Studies Program.
Under this program, participating countries evaluated climate change
mitigation options, assessed their vulnerability to climate change,
identified methods for adapting to climate change, and developed plans
for responding to climate change.
- U.S. Country Studies Program
- The countries participating in the USCSP have produced summary reports
for the sectors they studied (GHG Emissions Inventory; Assessment
of Vulnerability and Adaptation to Climate Change; and GHG Mitigation
Options). Countries for which electronic versions are currently
available are Bulgaria, Ethiopia, Fiji, Hungary, Kazakhstan, Nepal,
the Russian Federation, Uganda, Ukraine, and Uruguay.
- The Potential Health Impacts
of Climate Variability and Change for the United States: Executive Summary
of the Report of the Health Sector of the U.S. National Assessment
- As part of a congressionally mandated national study of the impacts
of climate variability and change in the United States, the authors
assessed the potential impacts that projected changes in climate (based
on modeled data developed for the national study) might have on a limited
number of health outcomes that are associated with weather and/or climate.
- A U.S. Carbon Cycle
- This integrated carbon cycle research plan was prepared at the request
of the Agencies of the U.S. Global Change Research Program and addresses
oceanic, atmospheric, and terrestrial components of the carbon cycle.
- 1999 - Newly Available
Agency Data Sets that Are Significantly Global Change Related
- Since its inception, the U.S. Global Change Research Program has had
the policy of full and open data availability. This policy has already
been implemented not only through the participating agencies but through
many inter-agency mechanisms such as publications, Internet based services,
and in many international settings. This second of a series of yearly
publications represents another important step in this interagency process
of making the data and information from the Global Change Research Program
available. It is particularly needed at this time since the users of
this data and information have expanded from being primarily researchers
to being a full mix that also includes educators, those making assessments
of potential effects of global change, the commercial world, and the
public as well as policy makers at all levels. One of this publication’s
objectives is to provide this diverse user community with a concise
summary of what data has been cataloged and made newly available each
- Environmental Effects
of Ozone Depletion: 1999 Interim Summary
- The United Nations Environment Programme (UNEP) Assessment Panel on
the Environmental Effects of Ozone Depletion produced this interim summary.
The assessment is given in seven sections: changes in ultraviolet radiation,
effects on human and animal health, effects on terrestrial ecosystems,
effects on aquatic ecosystems, effects on biogeochemical cycles, effects
on air quality, and effects on materials.
