A new version (v3) of the CORDEX-CMIP6 archiving specifications for dynamical downscaling are now available to be applied for the upcoming publication of CORDEX-CMIP6 data in ESGF Next Generation (ESGF-NG). This new version introduces minor revisions aimed at resolving inconsistencies identified by the community, and to make explicit some existing practices in the community; notably, to enable the publication of ocean and other model component output on different grids. It also points to the quality checking tools that can be used to test the model output for compliance with the specifications. A major change is the strong recommendation to repack the internal structure of all output files, as a final step in the post-processing. Failing to do so will hinder data replication and efficient use of CORDEX data on ESGF-NG. This release replaces the previous version from May 2025 and should be used for all CORDEX-CMIP6 dynamical downscaling outputs.

In a publication in Geoscientific Model Development (van Vuuren et al., 2026), the ScenarioMIP team describes a new set of global emissions scenarios that will form the basis for climate research as part of the ongoing phase of the Coupled Model Intercomparison Project – CMIP7. Two important changes from the CMIP6 scenarios are that, during the 21st century, the highest global emissions scenario is now lower than in previous scenario sets, while the preliminary estimate of global temperature change associated with the lowest emissions scenario no longer remains below 1.5°C. The new high-end scenario still leads to substantial climate change, and uncertainties in the climate system mean that global warming could still exceed 4°C by 2100.

More than 60 researchers, practitioners, operational agencies and industry representatives from across regions gathered for the GPEX Multi-stakeholder Workshop on 5–6 March to discuss the latest advances in precipitation science and the evolving role of the WCRP Global Precipitation EXperiment (GPEX).

The discussions went beyond the science itself. A key focus was how we translate advances in precipitation research into knowledge, information and services that stakeholders can understand, use and act upon- from robust science to better risk-informed decision making.

A turning point as we shape the next phase of GPEX development- strengthening collaboration across research institutions, operational centres, space agencies and other partners.
