[Coral-List] Question Thermal vs PH shift

[Simon Donner]

It is rather depressing to read scientists arguing over which threat (T vs.
pH) is worse. I will say that the discussion of poleward movement of corals
confuses geological and socio/ecological thinking. Even if corals could all
move poleward, that would not mean establishment, in the near or even the
future, of coral reef ecosystems as we know them. And even if that could
happen, the more equatorial human communities that had depended on
(presumably degraded) coral reefs are still in trouble.
