PRIMAP

What emissions reductions are required to stay well below 2°C or to limit the temperature increase to 1.5 °C?

How much will greenhouse gas emissions have to be reduced to avoid a particular climate impact?

Will post-2015 agreements ensure a high probability of e.g. saving coral reefs?

PRIMAP aims to synthesize earth system science and multi-model impact projections to address these crucial research questions for science and society alike.

PRIMAP traces the entire modelling chain from Greenhouse Gas (GHG) emissions to impacts on the natural and built environment, which is visualised here.

1. Emissions module

Assesses global GHG emission pathways under different mitigation assumption and equity proposals.

See relevant publications.

2. Climate module

The reduced-complexity climate model MAGICC produces highly efficient probabilistic global mean temperature projections for arbitrary emission scenarios.

See relevant publications.

3. Impact emulator

EXPACT provides probabilistic projections of climate impacts, such as regional sea level rise and coral bleaching in terms of global mean temperature change.  This prototype impact emulator accounts for simultaneous occurrence of impacts from extreme events, based on the ISI-MIP database, and will be applied for comprehensive climate risk assessments.

See relevant publications.

The Paris-Reality-Check website offers an user-friendly portal to explore emissions data and scenarios, equity assessments and climate impacts of different emissions scenarios.
