I often hear this, and for the sake of discussion I tried to find some numbers. I could mainly find presentation notes[1], and half page (quite similarly structured) posts, even from the Great Barrier Reef Marine Park Authority[2]

Does anyone have a link to the research behind these releases? I don't doubt the effect of raising acidity and temperature, but would like to see a comparison to the aftermath of oil spills, radiation leaks etc. throughout the Pacific.
