The 2015 Paris Agreement sets out a global action plan to avoid dangerous climate
change by limiting global warming to well below 2°C, whilst pursuing efforts to limit
warming to 1.5°C. However, predicting how the climate will change over the next
20-50 years, as well as defining the emissions pathways that will set and keep the
world on track, requires a better understanding of how several human and natural factors
will affect the climate in coming decades. These include how atmospheric aerosols affect
the Earth's radiation budget, and the roles of clouds and oceans in driving climate change.
The EU-funded CONSTRAIN project, a consortium of 14 European partners, is developing a better
understanding of these variables, feeding them into climate models to reduce uncertainties, and
creating improved climate projections for the next 20-50 years on regional as well as global scales.
In doing so, CONSTRAIN will take full advantage of existing knowledge from the Sixth Phase of the
Coupled Model Intercomparison Project (CMIP6) as well as other Horizon 2020 and European Research
