'Coral bleaching and mortality will increase in frequency and magnitude over the next decades .' Analysis of the Coupled Model Intercomparison Project 5 ensemble projects the loss of coral reefs from most sites globally by 2050 under mid to high rates of warming . 'Under the A1B CO2 emission scenario, 99% of the reef locations will experience at least one severe bleaching event between 2090 and 2099, with limited evidence and low agreement that coral acclimation and/or adaptation will limit this trend.' 'The onset of global dissolution  is at an atmospheric CO2  of 560 ppm  and dissolution will be widespread in 2100' . 'A number of coral reefs could therefore keep up with the maximum rate of sea level rise  of 15.1 mm yr-1 projected for the end of the century , but lower net accretion  and increased turbidity will weaken this capability .'
