RCP8.5 conditions would look like ....

• CO₂ up to 490 ppm, up to 1.5^oC average increase in temperature. 10-30% of coral survive, annual bleaching, 0.45m sea rise

• CO₂ up to 650 ppm, up to 2^oC average increase in temperature. Reef not dominated by coral, annual bleaching, 0.52m sea rise

• CO₂ up to 1370ppm up to 4⁰C average increase.

  reef not dominated by coral annual bleaching, 0.75m sea rise

• CO₂ up to 850 ppm, up to 3^oC average increase in temperature. Reef not dominated by coral, annual bleaching, 0.55m sea rise

Dark patches in coral x-rays indicate

• no correlation can be formed from coral x-rays

• high levels of growth hence the dark colour

• bleaching only

• lack or calcification and possible stress events
