The HAPPI project (Half
a degree Additional warming, Prognosis and Projected Impacts) is an international effort, listing more than 35 different institutions worldwide as collaborators.
Climate scenarios from the Half
a degree Additional warming, Projections, Prognosis and Impacts project (HAPPI) are largely consistent with transient scenarios extracted from RCP4.5 simulations of the Coupled Model Intercomparison Project phase 5 (CMIP5).
This article documents the design of the half
