Hi Gene,

I think we all (biologists and otherwise) understand what you are saying about
the geological record. Corals come and go and reefs die off and recover. All
else being equal, perhaps we need not worry about the latest reef decline.
However, all else is quite obviously not equal. Over the past several decades,
water quality has greatly deteriorated and reefs are facing direct disturbance
(e.g. sedimentation, pollution) from human activities in addition to
climate-related issues. Given that conditions over the past 50 years are nothing
like conditions over the previous 6000 years, how can you assume that what we
are seeing is simply another repetition of the geological record? Are you
certain that under the current (very different) conditions, reefs or coral
species that recovered millennia ago would still be able to do so today?

While there is no doubt that coral reef biologists can learn a great deal from
geology, I think some geologists could learn a lot from biologists, or from
simply looking forward for a change.
