Fig. 4: Frequency and distribution of persistent and transient opportunities.
From: Temporal dynamics of climate change exposure and opportunities for global marine biodiversity
a Frequency of persistent and transient thermal opportunities. b Frequency of transient opportunities closed by exposure to temperatures above (warm exposure) and below (cold exposure) the realised thermal niche limits of the species. c Bivariate maps showing the geographical distribution of the median number of warm- and cold-exposed opportunities for three emission scenarios. Transient opportunities closed due to warm exposure are mostly concentrated in the tropics and in the North Atlantic Ocean, while those closed due to cold exposure are concentrated in temperate and polar regions, especially in the northern hemisphere. The key indicates the number of transient opportunities. All figures show the mean value across nine climate models. Source Data for this figure can be found in ref. 72.
