Earth System Science for Climate Decisions

Funds research that closes major climate-science gaps, reduces projection uncertainty and supplies evidence for policy assessments.

ClosedEuropean CommissionEU

Climate assessments depend on an evolving evidence base, yet important Earth-system processes still carry large uncertainties or conflicting findings. This topic supports research that can materially improve future global and regional assessments and the policies built on them.

Projects must address critical knowledge or data gaps identified by the IPCC or other authoritative assessments. The work can improve understanding of Earth-system processes, observations, models and projections, provided it explains how the resulting evidence reduces uncertainty and responds to policy needs.
