The 2nd Regional Climate Change Conference 2026 (RCCC) will provide a unique opportunity to share science, on-the-ground experiences and policy developments across different countries and communities, with a special focus on early career professionals and female participants, especially from the Global south. RCCC aims to foster future research through the use of state-of-the-art methods in climate modelling, regional/local climate impacts, and risk assessment. RCCC is intended to be held bi-annually on a rotating basis in Sri Lanka and Thailand.
