Eric, there has been a lot of complex work done on coral bleaching but most of it simply ignores one obvious possible cause - CO2 starvation! They just didn't bother to measure CO2 levels in their experiments even though they obviously could be crucial in the chemistry of photosynthesis. It simply isn't done for a researcher to suggest that lack of CO2 in hotter still water (the classic situation that causes bleaching) is the cause when their funding came from sources desperate to blame too much CO2 in the atmosphere as the cause.. It all gets too confusing and where would the next grant come from? Many papers however seem to look at the possibility of CO2 starvation of the corals in warmer waters as a factor, but refrain from including that in their summations. In fact the only study I could find that suggested that reduced CO2 (simply physics - warmer water holds less gas) could be a factor in coral bleaching was done by Yonge & Nicholls in 1931. It seems curious that they were even looking at coral bleaching in those days; it must have been the "climate change" that they were anticipating. Nobody seems to have attempted to duplicate their work even though modern instrumentation would make it a whole lot easier.
