A newly developed Climate Risk Index for • Under both scenarios, the proportion of species at high or critical climate change Biodiversity1 was used to map critical risk risk tended to be higher closer to coastlines, areas for over 2000 marine species and 90 particularly in the Gulf of St. [...] Within each grid cell (here 0.25°) across the native geographic distribution of cod high climate risks throughout within the the northwest Atlantic, 12 standardized climate indices are calculated and used their distribution areas, but this to define the three dimensions of climate vulnerability: present-day sensitivity (a; blue), species is already at critical levels projected future exposure (b;. [...] The dimensions are used to calculate cod climate vulnerability (d), and the relative vulnerability scores are translated in parts of the southern Gulf of into absolute climate risk categories for cod at all locations across its distribution (e). [...] G kto r Many of the highest-value species received considerable benefits from lowering emissions, with Forage fish benefitted the most efforts to mitigate climate change under the low-emissions scenario, reducing the proportion of their and herring, capelin, and Northern distributions at high exposure Elasmobranchs such as skates shrimp stocks were the least risk. [...] ORG Pelagic fishes Invertebrates Demersal fishes Elasmobranchs RECOMMENDATIONS FOR DECISION-MAKERS • Use climate risk tools to identify the • Consider dynamic and adaptive species and locations that are most management, where harvest rates can urgently in need of climate adaptation be adopted based on real-time data on and take the steps necessary to help.
