During COP21 the parties to the Paris Agreement agreed on “holding the increase in the global average temperature to well below 2°C above pre-industrial levels and to pursue efforts to limit the temperature increase to 1.5 °C above pre-industrial levels”. These efforts must also be informed by solid scientific knowledge.
The Paris Agreement therefore invited IPCC to prepare a special report on the impacts of a global warming of 1.5°C above pre-industrial levels, as well as related greenhouse gas emission pathways, to be completed by 2018. HappiEVA is one of several scientific initiatives intended to strengthen the scientific basis of the special report.
Here is the list of the contributors to the IPCC Special Report on 1.5°C Global Warming.
