Twelfth Session of Working Group I (WGI) of the Intergovernmental Panel on Climate Change (IPCC) and Thirty-sixth Session of the IPC

23-26 September 2013 | Stockholm, Sweden

The 12th session of Working Group I (WGI) of the Intergovernmental Panel on Climate Change (IPCC) and the 36th session of the IPCC were held from 23-26 September 2013 in Stockholm, Sweden. The meeting was attended by more than 400 participants, including representatives from governments, the United Nations, and intergovernmental and observer organizations, and drew worldwide media attention.

The WGI session focused on finalizing its contribution to the Fifth Assessment Report (AR5). The process to prepare the AR5 was launched by the IPCC in 2008. The WGI contribution is the first in the series of four reports with the WGII assessment on impacts, adaptation and vulnerability scheduled for finalization in March 2014; the WGIII contribution on options for mitigating climate change to be finalized in April 2014, and the AR5 Synthesis Report to be completed in October 2014.

During the four-day meeting, delegates met in plenary, informally and in contact groups to consider the WGI contribution to the IPCC AR5 titled, “Climate Change 2013: The Physical Science Basis.” Delegates were assisted by short informal presentations by the Coordinating Lead Authors (CLAs) on various sections and topics of the Summary for Policymakers (SPM). At the end of the meeting, WGI approved the SPM and accepted the underlying report including the Technical Summary and annexes.

Subsequently, the IPCC convened to formally adopt the work by WGI. The approved SPM can be found on the IPCC website http://ipcc.ch.
