Paired with global warming….
● Changes to range,
community
composition, and
increased stress
● Possibility of coral
bleach...
So what does it mean for the future?
Wait… this has happened before?

Sharp decrease in calcium
carbonate shows major
decrease in calcifying organisms

how do we know that?
Can we stop it?
Our future remains to
be seen!
