Satellite observations show significant declines in Arctic sea ice cover in recent decades as the climate has warmed,[1] with impacts on fish and wildlife habitats that are important for subsistence, recreation, and tourist activities in the region. Retreating sea ice also contributes to increased storm surge, coastal flooding, and coastal erosion.[2] Arctic sea ice plays a key role in moderating climate within and beyond the region, and understanding sea ice change is critical to projections of future...

Highlights
Since 1989, the U.S. Global Change Research Program (USGCRP) has submitted annual reports to Congress called Our Changing Planet. The reports describe the status of USGCRP research activities, provide progress updates, and document recent accomplishments
In particular, Our Changing Planet highlights progress and accomplishments in interagency activities. These highlights represent the broad spectrum of USGCRP activities that extend from Earth system observations, modeling, and fundamental research through synthesis and assessment, decision support, education, and public engagement.
