Temporal Relationships (IMAGE) University of North Carolina at Chapel Hill Caption Temporal relationships between ocean warming and coral cover decline. the blue and pink bars show the average annual temperature anomalies for land and sea from a 1961-1990 baseline [based on the Hadley Centre Climatic Research Unit Temperature 4 (HadCRUT4) data set], and the black line shows the average annual coral-reef sea-surface temperacture [from the Hadley Centre Global Sea Ice and Sea Surface Temperature 1 (HadISST1) data set]. The orange line shows the temporal trend in absolute mean Caribbean coral cover (based on a regional meta-analysis). Figure adapted from Gardner et al. (2003) and Lough et al. (2018.
