"but the mass die-offs we're seeing are because the world's coral reefs will be dead by 2050"
I've argued this point before here but I don't believe that will happen by 2050 at all.
For several reasons, not the least of which is there are fossilized reefs from epochs with much much higher C02 levels (and temperatures) then we will see any time in the near future.
I was in Mexico last year. On the reefs. Diving. They were in good shape with lots of young corals and very little die off. Sunscreen and human activity are a threat.
Not getting into the whole debate on warming (I believe something is happening) but this coral die off claim I do not believe at all. Particularly the 30 years bit.
- jasonwatkinspdx 6y agoI mean, the internet is here if you'd like to learn the actual science. This is a topic we understand and have ample empirical evidence on. I'd start by considering that most species were also quite different during the high CO2 era. And while I'm glad you had fun in Mexico and what you saw there looked healthy, that doesn't somehow erase the bleaching we see on reefs globally. That the coral is dying, rapidly, is not under contention. It's a clearly known fact.

- mythrwy 6y agoThe species may have been different but they were constructed with the same calcium skeletons that are claimed to be much under threat from acid producing C02. Yet they thrived and left fossil remains in environments that were much much much more C02 rich and warmer.
