A trio of researchers from CEA Saclay, Sorbonne Université-CNRS-IRD-MNHN and the Alfred Wegener Institute, respectively, has found evidence that peak ocean acidification in the Arctic Ocean may shift from winter to summer by 2100. In their paper published in the journal Nature, James Orr, Lester Kwiatkowski and Hans-Otto Pörtner describe their study of acidification of the Arctic Ocean in the future. A News and Views piece in the same journal also outlines their findings.
