Change in environmental suitability for pathogenic Vibrio outbreaks as determined by observed correlations with sea surface temperatures and ocean salinity. This model suggests that suitability is increasing predominantly in the northern hemisphere (top; northern latitudes=40-70°N; tropical latitudes=25°S-40°N; southern latitudes=25-40°S). More detailed analysis by regions shows, for example, that the Baltic Sea (middle) and the United States north east coast (bottom) are also increasingly suitable for Vibrio outbreaks due to climate change.
