Countries should integrate and implement Early Warning Systems (EWS) and Climate Information Services (CIS) into their National Adaptation Plans (NAPs) and Nationally Determined Contributions (NDCs), pursuant to the UN’s goal of “Early Warnings for All by 2027.” EWS and CIS are crucial for saving lives, managing climate risks, and building resilience, especially in vulnerable regions and communities. The paper highlights examples in which these systems have been incorporated in national plans in ways that attract investment and improve climate adaptation. It also sets out related actions that should be prioritized.
