Half a degree Additional warming, Prognosis and Projected Impacts' (HAPPI)
The project ‘Half a degree Additional warming, Prognosis and Projected Impacts’ (HAPPI) aims at assessing the difference in climate impacts between 1.5°C and 2°C using targeted multi-ensemble simulations. The simulations are designed to allow for robust assessment of changing risks in extreme weather events.

The HAPPI-DE project coordinates the German contributions to the Half a degree Additional warming, Prognosis and Projected Impacts initiative (HAPPI). HAPPI is a collaboration of 44 scientific institutions to generate new scenarios to quantify the relative risks associated with 1.5°C and 2°C of warming focusing on extreme weather and the relative risks of low-probability extreme weather events.
More information available on the project website.
Climate Analytics is coordinating the consortium that will contribute global and regional climate model simulations to the HAPPI, as well as impact model simulations in the agriculture and water sector. The project’s main aim is to produce scientific publications in time for the IPCC special report on 1.5°C in 2018.
