The extreme complexity of Earth's interconnected physical and biological systems cannot be overstated. It is very very very very hard to understand how they all work together — probably impossible, in fact, with our limited human brains.
That's why it was NOT a good idea to conduct an insanely dangerous experiment, pumping hundreds of billions of tons of carbon dioxide into the air, radically altering atmospheric chemistry in the geological blink of an eye. But that's what our rulers have done.
At this point no one really has a clear grasp on how much this might change things, or how quickly and just where those changes will happen, and how they could interact.
The future is perilously uncertain...
"How climate change is messing up the ocean's biological clock, with unknown long-term consequences"
I'm no scientist, and it gives me no pleasure, but every prediction I've made since the 70s on the state of the planet has come true, and none of it has been good.
Fwiw, I predict these times now are the best it will be from here on out, and it's all downhill from here.
