The Intergovernmental Panel on Climate Change (IPCC) is seeking responses to a questionnaire that will inform a special report on the impacts of a 1.5°C increase in global temperature. The Steering Committee for the Special Report on 1.5ºC has prepared this questionnaire ahead of the Scoping Meeting to be held in August 2016, with the intent to help form the structure and contents of the report.

The questionnaire is available here: https://www.ipcc.ch/report/sr15/pdf/sr15_prescoping_questionnaire.pdf

If you wish to contribute, please return the questionnaire to: tsu@ipcc-wg1.universite-paris-saclay.fr by 15 July 2016.

For further information you can visit the IPCC webpage: https://www.ipcc.ch/report/sr15/ or consult the Future Earth website: http://futureearth.org/news/complete-questionnaire-upcoming-ipcc-report-15degc-climate-target
