Reference Model for an Open Archival Information System (OAIS)

Description: This document is a technical Recommendation for use in developing a broader consensus on what is required for an archive to provide permanent, or indefinite long-term, preservation of digital information. This Recommendation establishes a common framework of terms and concepts which comprise an Open Archival information System (OAIS). It allows existing and future archives to be more meaningfully compared and contrasted. It provides a basis for further standardization within an archival context and it should promote greater vendor awareness of, and support of, archival requirements. Through the process of normal evolution, it is expected that expansion, deletion, or modification of this document may occur. This Recommendation is therefore subject to CCSDS document management and change control procedures which are defined in Procedures Manual for the Consultative Committee for Space Data Systems. Current versions of CCSDS documents are maintained at the CCSDS Web site: http://www.ccsds.org/

Emissions Scenarios

Description: This Report describes climate change scenarios that extend to the end of the 21st century and how they were developed. The scenarios cover a wide range of the main driving forces of future emissions, from demographic to technological and economic developments. The set of emissions scenarios is based on an extensive assessment of the literature, six alternative modeling approaches, and an "open process" that solicited wide participation and feedback from many groups and individuals. The SRES scenarios include the range of emissions of all relevant species of greenhouse gases (GHGs) and sulfur and their driving forces.

Land Use, Land-Use Change, and Forestry

Description: The Intergovernmental Panel on Climate Change (IPCC) Special Report on Land Use, Land-Use Change, and Forestry (SR-LULUCF) has been prepared in response to a request from the United Nations Framework Convention on Climate Change (UNFCCC) Subsidiary Body for Scientific and Technological Advice (SBSTA). At its eighth session in Bonn, Germany, 2-12 Ju and technical implications of carbon sequestration strategies related to land use, land-use change, and forestry activities. The scope, structure, and outline of this Special Report was approved by the IPCC in plenary meetings during its Fourteenth Session. This Special Report examines several key questions relating to the exchange of carbon between the atmosphere and the terrestrial pool of aboveground biomass, below-ground biomass, and soils. Vegetation exchanges carbon dioxide between the atmosphere and the terrestrial biosphere through photosynthesis and plant and soil respiration. This natural exchange has been occurring for hundreds of millions of years. Humans are changing the natural rate of exchange of carbon between the atmosphere and the terrestrial biosphere through land use, land-use change, and forestry activities. The aim of the SR-LULUCF is to assist the Parties to the Kyoto Protocol by providing relevant scientific and technical information to describe how the global carbon cycle operates and what the broad-scale opportunities and implications of ARD and additional human-induced activities are, now and in the future. This Special Report also identifies questions that Parties to the Protocol may wish to consider regarding definitions and accounting rules.

IPCC Special Report Aviation and the Global Atmosphere: Summary for Policymakers

Description: The Intergovernmental Panel on Climate Change (IPCC) was jointly established by the World Meteorological Organization (WMO) and the United Nations Environment Programme (UNEP) in 1988 to: (i) assess available information on the science, the impacts, and the economics of, and the options for mitigating and/or adapting to, climate change and (ii) provide, on request, scientific/technical/socio-economic advice to the Conference of the Parties (COP) to the United Nations Framework Convention on Climate Change (UNFCCC). Since then the IPCC has produced a series of Assessment Reports, Special Reports, Technical Papers, methodologies, and other products that have become standard works of reference, widely used by policymakers, scientists, and other experts. This Special Report was prepared following a request from the International Civil Aviation Organization (ICAO) and the Parties to the Montreal Protocol on Substances that Deplete the Ozone Layer. The state of understanding of the relevant science of the atmosphere, aviation technology, and socio-economic issues associated with mitigation options is assessed and reported for both subsonic and supersonic fleets. The potential effects that aviation has had in the past and may have in the future on both stratospheric ozone depletion and global climate change are covered; environmental impacts of aviation at the local scale, however, are not addressed. The report synthesizes the findings to identify and characterize options for mitigating future impacts.

The Regional Impacts of Climate Change: An Assessment of Vulnerability

Description: The Intergovernmental Panel on Climate Change (IPCC) was jointly established by the World Meteorological Organization and the United Nations Environment Programme in 1988 to assess the scientific and technical literature on climate change, the potential impacts of changes in climate, and options for adaption to and mitigation of climate change. Since its inception, the IPCC has produced a series of Assessment Reports, Special Reports, Technical Papers, methodologies and other products which have become standard works of reference, widely used by policymakers, scientists and other experts. This Special Report, which has been produced by Working Group II of the IPCC, builds on the Working Group's contribution to the Second Assessment Report (SAR), and incorporates more recent information made available since mid-1995. It has been prepared in response to a request from the Subsidiary Body for Scientific and Technological Advice (SBSTA) of the UN Framework Convention on Climate Change (UNFCCC). It addresses an important question posed by the Conference of the Parties (COP) to the UNFCCC, namely, the degree to which human conditions and the natural environment are vulnerable to the potential effects of climate change. The report establishes a common base of information regarding the potential costs and benefits of climatic change, including the evaluation of uncertainties, to help the COP determine what adaptation and mitigation measures might be justified. The report consists of vulnerability assessments for 10 regions that comprise the Earth's entire land surface and adjoining coastal seas: Africa, Arid Western Asia (including the Middle East), Australasia, Europe, Latin America, North America, the Polar Regions (The Arctic and the Antarctic), Small Island States, Temperate Asia and Tropical Asia. It also includes several annexes that provide information about climate observations, climate projections, vegetation distribution projections and socioeconomic trends.
