Global Warming of 1.5 °C
an IPCC special report on the impacts of global warming of 1.5 °C above pre-industrial levels and related global greenhouse gas emission pathways, in the context of strengthening the global response to the threat of climate change, sustainable development, and efforts to eradicate poverty.
History
In its decision on the adoption of the Paris Agreement, the Conference of Parties (COP) to the United Nations Framework Convention on Climate Change (UNFCCC) at its 21st Session in Paris, France (30 November to 11 December 2015), invited the IPCC to provide a special report in 2018 on the impacts of global warming of 1.5 °C above pre-industrial levels and related global greenhouse gas emission pathways.
At its 43rd Session (Nairobi, Kenya, 11 – 13 April 2016), the IPCC Panel decided to accept the invitation from the UNFCCC to provide a special report in 2018 on the impacts of global warming of 1.5 ºC above pre-industrial levels and related global greenhouse gas emission pathways, and to prepare a Special Report on this topic in the context of strengthening the global response to the threat of climate change, sustainable development and efforts to eradicate poverty.
The scoping meeting that prepared the draft outline for the Special Report was held on 15 – 18 August 2016 in Geneva, Switzerland.
During its 44th Session (Bangkok, Thailand, 17-20 October 2016), the Panel approved the outline of Global Warming of 1.5 ºC, an IPCC Special report on the impacts of global warming of 1.5 ºC above pre-industrial levels and related global greenhouse gas emission pathways, in the context of strengthening the global response to the threat of climate change, sustainable development, and efforts to eradicate poverty.
The Special Report was developed under the joint scientific leadership of Working Groups I, II and III with support from WGI TSU.
