According to a new National Climate Assessment report, the nation's valuable ocean ecosystems and marine resources are being affected by a changing climate. These impacts are expected to increase in coming years, putting marine resources — and the people and economies that depend on them — at risk.
The United States' 28 National Estuarine Research Reserves (NERR) are experiencing negative effects of human and climate-related stressors, according to a new report from NOAA's National Ocean Service. This is the first national-scale climate sensitivity analysis of estuaries to help coastal managers protect the health of estuaries.

Climate normals are the average values of meteorological parameters -- such as temperature, precipitation, frost/freeze data, and snowfall data -- over 30-year spans. The climate normals data help describe typical climate conditions for a given place and time of year, and are used as a baseline to which current conditions can be compared.
