Summary/Abstract
As global climate change progresses, it is likely to change the global marine mercury cycle through higher seawater temperatures, lower wind speeds, greater incoming sunlight due to sea ice loss, and less transportation of mercury by marine organisms. All of these factors are likely to cause a greater concentration of toxic mercury in human food systems, which poses a threat to public health. This study uses a global ocean model to simulate projected impacts on mercury cycling over the next century, and finds substantial possibility of accumulation of toxic mercury in marine food systems vital to humans.
