Quick googling doesn't attribute coral dying to acidification, but temperature.

The thing that doesn't make sense to me is rising temperature might make a certain area uninhabitable by certain creatures, but it should open up new zones where it once was too cold.

My first memory of global warming scare stories might go back to the 90s, and the big concern then was the northward migration of killer hornets. Gotta maintain a cool planet to confine them to Mexico. Those illegal hornets are scary.

Yes, it's true for trees, shrubs, grass ,insects, molds, lichen, predators, killer whales, tropical diseases, parasites, different penguins, ................
Some, like bowhead whale will just perish in place. They only exist in the Arctic, and the Arctic is melting away. It's warm enough for Orca now, and they're freely predating bowheads, which have no defense, and nowhere to go.
Brown bear are moving into polar bear territory and competing for food.
Heat kill krill. 90% of marine life eat krill. The ocean fisheries will collapse. Sea birds will go. Seal. Penguin. Otter. Salmon. Trout. Sport fishing. Frogs. Salamander. Saguaro cactus. .................
Louisiana loses a football field worth of land every 45-minutes.The people of Iles de Jean Charles are America's first continental climate refugees.
I'd have to have my notes to keep going.
It's darkly fascinating.

Yeah, but what about coral?

I didn't know indoor baseball was a thing.

Icebergs don't need insane anchors.

If buyilding into the Earth is the goal, You accrete your columns and decks and then hoist them onto delivery boats, trains or airships. It puts me in mind of theose vats of brine in Old Towen Newport.

Wolf Hibertz life work was in remediating coral reefs in the Caribbean.

Wolf Hilbertz
Wolf Hartmut Hilbertz was a German-born futurist architect, inventor, and marine scientist. Notable contributions to science include the discovery of artificial mineral accretetion / biorock and its use to create electrified reefs.

My understanding is that coral is more robust than we thought, it can bleach out and then come back if conditions revert.

It's almost like the corrals have adapted to a changing climate over million of years.

[Ecky]

I imagine the corals we have will die, and we'll get new coral reefs over the next few tens of thousands of years, in the areas that have become newly hospitable to them.

Did anyone catch onto the concept of duckduckgo.com/?q=electrified+reefs

You can make an armature for new reefs with scrap iron and elecricity.

The problem is your ideas are both 100 years into the future, and 100 years in the past.

I expect increasing mastery of the various environments, but my crystal ball as to which technologies facilitate that is not clear. Probably AI will be leveraged for most problems. It's probably the defining technology of my generation. That or genetic engineering, but it will leverage AI.

I was born into an age that didn't know the atomic bomb. One morning before school I heard about Sputnik on my new transistor radio.

I agree with Fuller that humankind gained all the knowledge it needs to be a success in Universe by the 1970s. Marine electrodeposition is one example, the Apple ][ is another.

The last half-century hasn't been a total waste, a lot of groundwork has been laid

There's Plenty of Room at the Bottom
"There's Plenty of Room at the Bottom: An Invitation to Enter a New Field of Physics" was a lecture given by physicist Richard Feynman at the annual American Physical Society meeting at Caltech on December 29, 1959.

Some additional tidbits:
Aside from direct heat-related death, if the rate of sea level rise exceeds the maximum rate of corral carbonate accretion growth, factoring in subaerial wave action erosion, biological predation, volcanic thermal subsidence, and tectonic subsidence ( about 10mm / year ), the corral will drown.
There are 116 corral shallow banks that are presently drowned, among 261 corral atolls.
During the Holocene transgression, 18,000-years ago, the rate of sea level rise reached as high as 20mm / year.
As the poles are presently warming faster than elsewhere, and warming at a non-linear rate, the loss of the Arctic and Antarctic continental ice will continue to feed sea level rise, and at an ever-increasing rate.
The critical depth for corrals is 30-40 meters.
As the water gets deeper, sunlight becomes more feeble, which slows corral growth, creating a negative feedback loop.
The coupling between the atmosphere and ocean also means additional ocean thermal expansion, amplifying sea level rise.
Deeper water still, and more heat death.
