Technical summary climate change 2001: impacts, adaptation, and vulnerability
Scope and Approach of the Assessment
Mandate of the Assessment
The Intergovernmental Panel on Climate Change (IPCC) was established by World Meteorological Organization and United Nations Environmental Programme (UNEP) in 1988 to assess scientific, technical, and socioeconomic information that is relevant in understanding human-induced climate change, its potential impacts, and options for mitigation and adaptation. The IPCC currently is organized into three Working Groups: Working Group I (WGI) addresses observed and projected changes in climate; Working Group II (WGII) addresses vulnerability, impacts, and adaptation related to climate change; and Working Group III (WGIII) addresses options for mitigation of climate change.
This volume—Climate Change 2001: Impacts, Adaptation, and Vulnerability—is the WGII contribution to the IPCC’s Third Assessment Report (TAR) on scientific, technical, environmental, economic, and social issues associated with the climate system and climate change. 1 WGII’s mandate for the T AR is to assess the vulnerability of ecological systems, socioeconomic sectors, and human health to climate change as well as potential impacts of climate change, positive and negative, on these systems. This assessment also examines the feasibility of adaptation to enhance the positive effects of climate change and ameliorate negative effects. This new assessment builds on previous IPCC assessments, reexamining key findings of earlier assessments and emphasizing new information and implications from more recent studies.
