Terhaar, J., Torres, O., Bourgeois, T., & Kwiatkowski, L. (2021). Arctic Ocean acidification over the 21st century co-driven by anthropogenic carbon increases and freshening in the CMIP6 model ensemble. Biogeosciences, 18 (6), 2221–2240. https://doi.org/10.5194/bg-18-2221-2021
The uptake of carbon, emitted as a result of human activities, results in ocean acidification. The authors of this study analyse 21st-century projections of acidification in the Arctic Ocean, a region of particular vulnerability, using the latest generation of Earth system models. In this new generation of models there is a large decrease in the uncertainty associated with projections of Arctic Ocean acidification, with freshening playing a greater role in driving acidification than previously simulated.
