Coordination of adaptation policy goals cuts across cities to integrate them into international processes of climate policy formulation; coordination in cities produces effective collective outcomes, cementation of common standards and methodologies for climate action   . A collective global response has become a significant concern in international climate policy . The UNFCCC has adopted a role as an orchestrator, including providing framework for city governments . Within cities, coordination can arise from active programming; for example, in Rotterdam and New York City, local authorities adopted long-term objectives and conditions for action, bringing together a multiplicity of actors across sectors to orient contributions, share knowledge and coordinate actions . Where national politics is supportive, coordination between city and national government is an asset . The use of social media and digital mechanisms for coordination with public interest is ambiguous: in China, Weibo has facilitated an expansion of public engagement, although it remains top down and dominated by a few influencial actors . The pilot project #OurChangingClimate is one example of engaging youth with an understanding of their communities and their resilience or vulnerability to climate change .
