Temporary refugia for coral reefs in a warming world

As the Earth continues to warm over the coming decades, spatially extensive or ‘mass’ coral bleaching events—induced by persistently high water temperature—are expected to threaten the survival of coral reef ecosystems. Bleaching ‘hazard’ maps based on ensembles of the latest climate models and emissions pathways quantify the potential for mitigation activities to buy these ecosystems a temporary respite from this threat.
