IPCC WGII Technical Support Unit

Bremen, Germany


The IPCC Working Group II (WG II) assesses the vulnerability of socio-economic and natural systems to climate change, negative and positive consequences of climate change, and options for adapting to it.
It also takes into consideration the inter-relationship between vulnerability, adaptation and sustainable development. The assessed information is considered by sectors (water resources; ecosystems; food & forests; coastal systems; industry; human health) and regions (Africa; Asia; Australia & New Zealand; Europe; Latin America; North America; Polar Regions; Small Islands).

Intergovernmental Panel on Climate Change (IPCC)

Jointly established by the United Nations Environmental Programme (UNEP) and the World Meteorological Organization (WMO) in 1988, the IPCC prepares comprehensive and up-to-date assessments of policy-relevant scientific, technical, and socio-economic information relevant for understanding the scientific basis of climate change, potential impacts, and options for mitigation and adaptation. Read more...

Assessments are based upon peer-reviewed literature and publicly accessible non-journal literature, and are characterized by an extensive and open review process involving scientific/technical experts and governments before being accepted by the IPCC. The Panel was established to provide policymakers and other stakeholders with an objective source of information about climate change. The IPCC neither conducts research nor does it monitor climate-related data or parameters. Its reports are provided at regular intervals and immediately become standard works of reference, widely used by policymakers, experts, and students.
