Climate-driven changes of global marine mercury cycles in 2100.

ABSTRACT: Human exposure to monomethylmercury (CH₃Hg), a potent neurotoxin, is principally through the consumption of seafood. The formation of CH₃Hg and its bioaccumulation in marine food webs experience ongoing impacts of global climate warming and ocean biogeochemistry alterations. Employing a series of sensitivity experiments, here we explicitly consider the effects of climate change on marine mercury (Hg) cycling within a global ocean model in the hypothesized twenty-first century under the business-as-usual scenario. Even though the overall prediction is subjected to significant uncertainty, we identify several important climate change impact pathways. Elevated seawater temperature exacerbates elemental Hg (Hg⁰) evasion, while decreased surface wind speed reduc
