This proposal will address area b of the call "Maximizing the synergy of climate change research and innovation in Europe ". MAGICA maximizes the synergies between infrastructure investments and initiatives of climate change research and innovation across the European Research Area (ERA) by building upon and further implementing the Mission of JPI Climate in support to the international and European climate agenda (including the European Green Deal and Adaptation Strategy). MAGICA aims to accelerate the development, provision and exchange of knowledge from research and innovation to inform and support policy-making and climate actions via a better coordination of on-going and future initiatives and a more efficient use of resources. MAGICA will be based on a circular and iterative interactions among the strategic, scientific and societal components of climate change research and innovation. A scientific arena will be created to enhance the debate and discussion within the scientific community on climate R&I priorities, that will be synthesized in a Joint Strategic Research and Innovation Agenda on climate change for ERA 2025-2034. In addition, the creation of a regular forum with European Ministries of Research and Climate and other funding bodies will foster the coordination of the different national research policies in order to meet the ERA-wide priorities and needs identified by the scientific community. Finally, a multi-directional dialogue with different relevant social actors (from policy-makers to the younger generation) will be enhanced through different international conferences (e.g. ECCA, Climate Neutrality Forum), workshops and other innovative formats in order to inform citizens but also to detect the social needs concerning the transition to climate-neutrality and climate science. They will be incorporated into scientific community’s priorities for research, thus closing the feedback loop.
