Changes in global DMS production driven by increased CO2 levels and its impact on radiative forcing
Abstract Our study highlights the importance of understanding the future changes in dimethyl-sulfide (DMS), the largest natural sulfur source, in the context of ocean acidification driven by elevated CO2 levels. We found a strong negative correlation (R 2 = 0.89) between the partial pressure of carb...
