Thanks for the post, Andrew, It's good to see the work of Greg et al. gaining this type of independent verification of the work they started over a decade ago.
For the general reader, here is a short list of the prior work: a) The need for new ocean conservation strategies in a high-carbon dioxide world <http://www.nature.com/nclimate/journal/v2/n10/full/nclimate1555.html> b) *Reef *climate adaptation research and technology <http://ijc.cgpublisher.com/product/pub.185/prod.115> c) Ocean Acidification: A Serious Threat to Coral *Reef* <http://www.ajms.co.in/sites/ajms2015/index.php/ajms/article/view/1031> d) Asian Journal of Multidisciplinary Studies <http://www.academia.edu/download/44458290/Ocean_Acidification.pdf> This list is not exhaustive.
