The corals are casualties of surging global temperatures which have smashed historical records in the past year — caused mainly by fossil fuels driving up carbon emissions and accelerated by the El Niño weather pattern, which heats ocean temperatures in this part of the world.
The ocean will starve to death. People will too. Earth is rapidly becoming a wasteland. Often seems like too few seem to care and that’s probably just going to become more true as time goes on. It’s so deeply horrible.
It would be interesting to see if a CRISPR type technology could make coral reefs more resilient to climate change.
The difficulty is likely deciding which genes to turn on and which ones to turn off.
What scientists are doing instead is taking corals that are demonstrating heat-resistance, propagating them in labs, and trying to introduce them back into the wild; it’s a kind of directed evolution. The difficulty is lack of funding and keeping up with climate change.
