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.

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 Intergovernmental Panel on Climate Change's special report on 1.5°C in 2018.
