Debris, climate change threaten new Hawaiian marine monument


A remote location and special federal protection can’t shield a new Hawaiian national monument from debris, invasive species and climate change, according to a new report.

The National Oceanic and Atmospheric Administration’s peer-reviewed report is aimed at providing a baseline for monitoring the Papahanaumokuakea Marine National Monument and identifying management priorities.
