 Our economies, societies and ecosystems are deeply interconnected. When floods lead an international port to suspend operations, when heat waves and droughts damage crops, that people in countries across the world are waiting to eat, when glaciers melt high in the mountains and lead to catastrophes for people downstream, we see that the impacts of climate change cascade across national borders. Climate risk is a shared reality. Adaptation must become a shared responsibility. This means new understandings of adaptation as managing risk in an interconnected world, new initiatives on adaptation, moving beyond small-scale projects and domestic policies, new actors in adaptation including finance, foreign affairs and trade ministries, new scales of cooperation in adaptation between countries and regions. Only by working together can we build our collective resilience. It's time to shift the narrative on adaptation.
