Globally, average sea level has risen over the past several decades as ocean waters have warmed. While the ocean as a whole has absorbed a huge amount of heat from the warming atmosphere, ocean currents transport that heat differently across regions, contributing to significant regional variations in the amount of sea level change. Understanding changes in ocean heat content and the role of currents in shaping patterns of warming is critical to assessing current and future global and regional climate change, sea level rise, and coastal flooding risk.[1]...

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.
