From: Warming Trends and Bleaching Stress of the World’s Coral Reefs 1985–2012

Histograms of thermal history metrics for global reef locations (n = 60,710).
Global summary of the data distribution for (a) annual and (b) warm-season trends; (c) bleaching-level thermal stress events; (d) warmest month; (e) stress onset; and (f) warm-season temperature variability, 1985–2012. Warm-season temperature variability is the standard deviation of warm-season temperatures expressed as a percentage of the climatological range. Global averages ± one standard deviation are shown in plots (a,b,c and f. Data are provided for each histogram in Table S1.
