Climate change is affecting global ecosystems, natural resources, and human well-being. The near- and long-term future sustainable development of society requires robust climate change information at regional scales. To contribute to the purpose mentioned above, the World Climate Research Programme’s Coordinated Regional Climate Downscaling Experiment (WCRP CORDEX) initialised a collaboration with the Asia-Pacific Network for Global Change Research (APN), as the two programmes share common goals in advocating climate science as well as transferring climate knowledge for effective management. This APN project, entitled “Promoting Involvement of Early Career Scientists from the Asia-Pacific Region in Regional Integrated and Sustainable Development through Active Participation and Networking”, was a result of this collaboration. Specifically, the project was aimed at supporting early-career scientists from the Asia-Pacific region to attend an international science conference on regional climate science (ICRC-CORDEX 2019) and facilitate them in international partnership-building. It also contributed to enhancing communication and cooperation amongst regional climate research teams within and beyond the Asia-Pacific region. As one of the most important activities of the conference, the project supported an event for early-career scientists. The completion of the project consolidated global collaboration between the climate research community and that of adaptation-impact studies, as well as facilitated interaction with end-users. It was also a successful showcase of the scientific strategies of APN and CORDEX.
