Reclassification of data layers used in the exposure to CC‐OA submodel, where 5 indicates the highest exposure to CC‐OA for the year 2100

Exposure	Sea surface temperature (°C) increase	Aragonite saturation depth (%) decline	Primary productivity (%) decline	CHHR cyclone index
1	0–2	<0	<0	1–2
2	2–3	0–25	0–25	3–4
3	3–4	25–50	25–50	5–6
4	4–5	50–75	50–75	7–8
