Emerging and Re-emerging Infectious Diseases: Links to Environmental Change
Abrupt Climate Change: Ocean Salinity Changes and Potential Impacts on Ocean Circulation

This section presents some of the latest evidence from scientific research that can shed new light on ongoing and emerging environmental complexities and priority issues. This year's issues - the links between environmental change and emerging and re-emerging infectious diseases, and the possible consequences of reduced ocean salinity - were identified in consultation with the Scientific Committee on Problems of the Environment (SCOPE) of the International Council for Science (ICSU).
