Uncertainty in Analyzing Climate Change: Policy Implications. [PDF; 3.1 Mb] Report (dtd January 2005) from the United States Congress, Congressional Budget Office. "This Congressional Budget Office (CBO) paper—prepared at the request of the Ranking Member of the Senate Committee on Environment and Public Works—provides an overview of the sources of uncertainty that limit the understanding of climate change and complicate the assessment of policies to address it. The paper provides examples of the different ways that
analysts have addressed those uncertainties in formulating policy recommendations, illustrates the practical difficulties in doing so, and demonstrates the sensitivity of policy results to variations in assumptions about uncertain elements. Finally, it discusses the implications of uncertainty
for three different types of policy responses: research and development, mitigation of
greenhouse gas emissions, and adaptation to a warmer climate. In keeping with CBO’s mandate to provide objective, nonpartisan analysis, this paper makes no recommendations." (link posted 27 January 2005)

Radiative Forcing of Climate Change: Expanding the Concept and Addressing Uncertainties.  Report (released 16 Dec 2004) from the National Academies' Board on Atmospheric Sciences and Climate. The report, requested by the CCSP, examines the current state of knowledge regarding the direct and indirect radiative forcing effects of gases, aerosols, land-use, and solar variability on the climate of the Earth's surface and atmosphere. It also identifies research needed to improve our understanding of these effects. (link posted January 2005)

Addressing the Challenge of Global Climate Change

Paula J. Dobriansky, Under Secretary of State for Global Affairs: "Therefore it is our intention to implement policies that will foster these technology-based solutions -- that is the way we will address the challenge of global climate change. Significantly, we also believe that climate change should not be pursued in isolation, but should be handled as an integral part of a broad strategic paradigm of sustainable development, which features a balanced mix of environmentally sound, pro-economic growth policies. At the 2002 World Summit on Sustainable Development in Johannesburg and at the COP-8 meeting last year in New Delhi, we found strong and growing support for this position among developing countries."

Environmental Effects of Ozone Depletion and Its Interaction with Climate Change (2003 progress report)
Pursuant to Article 6 of the Montreal Protocol on Substances that Deplete the Ozone Layer under the Auspices of the United Nations Environment Programme (UNEP), the Environmental Effects Assessment Panel reported that ozone depletion, which caused increased surface ultraviolet-B (UV-B) radiation, consequently affected living organisms and also materials. New studies had confirmed and strengthened previous findings that UV-B radiation had serious adverse effects on the skin, eyes and immune system. Also, interactions between ozone depletion and climate change had environmental consequences, and the Panel had warned that ultraviolet damage to phytoplankton and other marine organisms might reduce the oceans' capacity as a sink for atmospheric carbon dioxide and so increase global warming.

Atmospheric Levels of Methane Stabilizing
The National Oceanic and Atmospheric Administration (NOAA) reports that atmospheric concentrations of methane, a potent greenhouse gas, have begun to level out after two centuries of increases. Methane levels have been constant for four years now, but scientists are not certain why the steady increases of the gas in the atmosphere since the dawn of the industrial age have stopped. One theory is that a decrease in fossil fuel production in the former Soviet Union may account for the decline. About 70 percent of methane emissions are connected with human activities -- the burning of fossil fuels, intestinal gas from livestock and farm animals, and the cultivation of rice paddies.

Statement of David W. Conover Before House Science Committee
As part of the President?s National Climate Change Technology Initiative, launched on June 11, 2001, the President directed the Secretary of Energy, in coordination with the Secretary of Commerce and the Administrator of the Environmental Protection Agency, to lead a multi-agency review of the Federal R&D portfolio and make recommendations. The Climate Change Technology Program (CCTP) was established in 2002 to implement the President?s Initiative. The CCTP is a multi-agency research and development (R&D) coordination activity, organized under the auspices of the Cabinet-level Committee on Climate Change Science and Technology Integration (CCCSTI). Participating Federal agencies include the Departments of Energy, Agriculture, Commerce, Defense, Health and Human Services, Interior, State, and Transportation, as well as the Environmental Protection Agency, the National Aeronautics and Space Administration, and the National Science Foundation.

Study Says African Dust Affects Climate in U.S. and Caribbean

A new study says that trade wind dust transported from West Africa can have significant implications for climate, atmospheric quality and public health in the Caribbean and the southeastern United States. A November 7 press release says results of the study, reported by researchers of the National Oceanic and Atmospheric Administration (NOAA) and published in the November 7 issue of the journal Science, show that trade wind dust transported from West Africa to Barbados in the eastern Caribbean is strongly linked to rainfall patterns in West Africa. The study says decreased rainfall in Africa results in a sharp increase in dust transported across the Atlantic the following year. (16KB PDF file)
