Two recent Intergovernmental Panel on Climate Change reports (IPCC 2018; Bindoff et al. 2019) summarize the existing projections of future coral bleaching, stating that coral reefs as we know them will all but disappear in a scenario of up to 2°C (3.6°F) warming. Additionally, up to 90% of coral reefs could be lost even with an increase of 1.5°C (2.7°F), which is now predicted to occur as soon as 2027. With the Tongan volcanic eruption appearing to have accelerated this process by 10 years, we are running out of time and need to take immediate action.
