The Convention on Climate Change sets an overall framework for intergovernmental efforts to tackle the challenge posed by climate change. It recognizes that the climate system is a shared resource whose stability can be affected by industrial and other emissions of carbon dioxide and other greenhouse gases. The Convention enjoys near universal membership, with 192 countries having ratified.
The Encyclopedia of the Atmospheric Environment is a one-stop source of information, for younger and older users alike, on a range of atmospheric issues, including air quality, acid rain, global warming and ozone depletion. It has been written by the Atmosphere, Climate & Environment Information Programme, and is supported by the Department for Environment, Food and Rural Affairs (DEFRA) in the UK.
This Digest is a faithful summary of the leading scientific consensus report produced in 2007 by the Intergovernmental Panel on Climate Change (IPCC): "Fourth Assessment Report (AR4)". More specifically, it is a summary of the reports by the three Working Groups: "The Physical Science Basis” (WGI), "Impacts, Adaptation and Vulnerability" (WGII), and "Mitigation of Climate Change" (WGIII).
The Task Force on National Greenhouse Gas Inventories (TFI) was established by the IPCC to oversee the IPCC National Greenhouse Gas Inventories Programme (IPCC-NGGIP). The objectives of the IPCC-NGGIP are to develop and refine an internationally-agreed methodology and software for the calculation and reporting of national GHG emissions and removals, and to encourage the widespread use of this methodology by countries participating in the IPCC and by signatories of the United Nations Framework Convention on Climate Change (UNFCCC).
The IPCC was established to provide the decision-makers and others interested in climate change with an objective source of information about climate change. The IPCC does not conduct any research nor does it monitor climate related data or parameters. Its role is to assess on a comprehensive, objective, open and transparent basis the latest scientific, technical and socio-economic literature produced worldwide relevant to the understanding of the risk of human-induced climate change, its observed and projected impacts and options for adaptation and mitigation.
