By this time yesterday, we were seeing everyone again for the Climate Research Communication Network 6th Meeting!
We kept doing what this network does best:connect project/comm managers & DEC people from EU climate projects so we don’t all reinvent the wheel &so we can amplify each other’s work💪🌍

Day 3. GA's last morning: Wrap-up & perspectives with @rolandseferian.bsky.social and others.
4.5 years together. In a little over a month the project ends. Today we celebrate what we built in science and in community.
#ESM2025inToulouse is over.
