Arctic wetlands play a number of crucial environmental roles, but they continue to be degraded and lost, with potentially dire global consequences. This report offers insights and identifies knowledge gaps, with the aim of supporting sustainable development and resilience in these areas. Arctic wetlands store an enormous amount of global carbon, offer crucial support for global biodiversity, and provide important ecosystem services for Indigenous and other communities. They also constitute considerable parts of the Earths remaining wilderness areas. Yet with rapidly warming temperatures and a dynamic human footprint these ecosystems are changing fundamentally, bringing both Arctic peoples and ecosystems closer to potential tipping points.
