What corals are we talking about? The corals that secrete CaCO3 and live in tropical areas? The "structural corals" that build reefs? Or the others, like the soft and cold water corals that don't? Because they are different. Structural corals corals have algae called zooxanthellae that live in their tissues commensually.

Corals expel their zooxanthellae in their tissues when they are stressed. Particularly when that stress is thermal. Now tropical corals live in a pretty narrow range of temperatures. If the temperature gets below about 17 degrees centigrade, the structural corals die. There are a couple of examples in the Gulf of Mexico north of The Flower Gardens. When the temperatures get above about 30 degrees, they start expelling their zooxanthellae. Without them long enough, they die. When parts of the reef start to die, then the reef gets infected by a whole host of invaders that kill off the rest of the reef. This has been an ongoing problem with The Great Barrier reef, and was first noted in the 1980s. But it is now a global phenomenon. I have no idea where you got your claim about the corals are doing fine, they aren't.

TLDR; You are just full of shit.

40 years ago was about 25 years after I first heard of global warming, or the Greenhouse Effect, as it called back then. The climatic effects of the warming weren't really explored, and I didn't think much about it at the time. 35 years ago, it went from being something in my physics texts to real life, with Hansen's testimony.

It looks to be 1.6 degrees C warmer, and the people who have been burned or flooded or droughted out of their homes would probably disagree with your opinion.
