There are wide varieties of corals and of their symbionts. To claim that they are all simultaneously going extinct in all seas and microclimates is absurd, and contradicts the evidence of their repeated adaptations to past climate variations over 500 million years as well as ignores the observation of their thriving across countless local seasonal and weather variations.

Straw man, no one claimed that there will be a complete extinction of coral, only that it will be 2 million years for coral to recover to pre-industrial levels.

Indeed. Coral reefs are important nursery's for many fish species, and reducing the areas for fish to safely grow up puts yet another pressure on declining fish stocks. Not to mention marine crustaceans that are also affected by rising acidity, and the overall warming trend of the ocean itself is pressuring all kinds of marine life that humanity depends on as a major food source.

Not only that, but the ocean is rising due to land-based glaciers/ice melting, the continental rebound involved from the reduced ice load, and yet more: the warming ocean is less dense and expands. The rising seas along with other factors mentioned also puts pressure on coral reefs, as they often cannot grow fast enough to catch up with that sweet-spot near the ocean surface!

> we are in fact in the midst of an extinction.

Literally two comments above.
