To boil it down: What if we could restore all the coral that has been
killed, and the next mass bleaching event or disease kills all that coral
and we are right back to where we were, except that in the mean time carbon
emissions continue unabated or even increase?? (they are increasing
currently in the states due to the strong economy, they are ABOVE "business
as usual", so far all the efforts to reduce them haven't even kept them
down to "business as usual" which is on track currently for 4 C or even 6 C
increase over pre-industrial, which will be lethal for corals, not to
mention people. No "super corals" can take 6 C, probably not 4 C,
according to Bay et al, 2017, current "best available science." So the big
question for me is, "isn't restoration wasted effort and money, if we don't
solve the root problem, which is emissions???"
Growing coral and restoring is great. BUT, if we don't solve the
root problem, the reef is doomed. No??? So where should the emphasis be??
Sorry for such a down message, but if we don't face up to reality
and get the root problem fixed, reefs and a lot of humans are doomed
(entire countries are likely to be uninhabitable in the future, too hot for
human survival, it's that bad).
Bay, R.A., Rose, Logan, and Palumbi. 2017. Genomic models predict
successful coral adaptation if future ocean warming rates are reduced.
