[Coral-List] faint hope on coral range expansion with global warming

Thanks for that reminder, Bill.
Global warming will bring with it not only increased sea surface
temperatures but also a rise in sea level. The corals will be
attempting to colonize a newly-inundated continental shelf during a
transgression: very similar to what happened during the early Holocene.
Walter Adey showed, more than 30 years ago,the length of time this
takes: >1000 years. Of course, that was during the early Holocene, when
the water was a lot cleaner.
I don't see a lot of hope here. At least, not in my lifetime.
