Here, we document the design of the half a degree additional warming, projections, prognosis and impacts (HAPPI) experiment. HAPPI provides a framework for the generation of climate data describing how the climate, and in particular extreme weather, might differ from the present day in worlds that are 1.5 and 2.0 °C warmer than pre-industrial conditions.

Regional climate signals at specific global warming levels, and especially the differences between 1.5°C and 2°C, are not well constrained in the science. This article reviews alternative approaches for identifying regional climate signals associated with global temperature limits, and evaluates the extent to which they constitute a sound basis for impacts analysis.

We look back at how our work reflected and fed into the global priorities following the adoption of the Paris Agreement.
