The Copernicus Climate Change Service (C3S) provides authoritative information about the past, present and future climate that supports adaptation policies in Europe. The service holds its 6th General Assembly to reflect on past achievements and shape together the future of the service. This year's Assembly focuses on data coverage and infrastructure, user engagement, and communication activities, as well as hosting the launch of the new Copernicus Energy Hub, a one-stop shop for products and information to support the energy sector under the changing climate.
