The Intergovernmental Panel on Climate Change (IPCC) has been established by WMO and UNEP to assess scientific, technical and socio-economic information relevant for the understanding of climate change, its potential impacts and options for adaptation and mitigation. It is open to all Members of the UN and of WMO. The IPCC Working Group I (WG I) assesses the physical scientific aspects of the climate system and climate change.






The mission of the Technical Support Unit of Working Group I of the IPCC for the Fifth Assessment Cycle is accomplished and therefore the office has been closed down.


Please note that this website will no longer be updated.


The work of Working Group I of the IPCC for the Sixth Assessment Cycle will be continued by the next TSU which is in the process of being set up near Paris, France. Please make sure to visit their website once it will be up and running.


Thank you for the interest in the work of the IPCC and for your support throughout the years. All the best!
