[Coral-List] Ocean acidification/temperature relationship on marine calcification

Dear Joan,

Can you clarify for the Coral-List how increasing sea surface temperature
affects the calcification challenge in corals with increasing acidification?

Ben McNeil's research on Porites in Australia shows that calcification
increases with increasing acidification and increasing sea surface
temperature.  The research by Marshall and Clode shows a bell-shape
calcification trajectory (i.e., increasing calcification up to 2-3degC
warming and then declining  after that).

Was the relationship of increasing sea surface temperatures and increasing
acidification on calcification discussed at the workshop?

It seems like all the recent calcification challenge press releases coming
out regarding increasing acidification are not put into context with respect
to increasing sea surface temperature.

Your thoughts/guidance would be appreciated, so we can all respond to these
calcification challenge questions accurately.
