The extreme heat has devastated corals. As a former marine scientist, this is a truly heartbreaking read:

“The coral didn’t even have a chance to bleach, it just died. It just felt like, ‘Oh my God, we’re in the apocalypse.’ What’s happening?”

I remember diving in The Keys when I was a kid. This is dreadful.

And because we are in an El Nino cycle, I believe I read that 2024 is likely to be even hotter in the region, regardless of what we do.

I hate being negative, but I feel that the ecological crash is already guaranteed regardless of what we manage to get corporations and denialists to do to modify their behavior. The question isn't will it crash, but what will be left afterward.
Earth will go on... humanity has no such guarantee.
