I live on an island. I’m worried about climate change. Also volcanos.

I know this sounds crazy. If the ocean was really that toxic, I’d starve long before the gas suffocated me. If for no other reason than boats have zero incentive to come.

But like, is this possible? Has it ever happened in history? I know there’s a lake somewhere that killed a whole town. Don’t remember where I heard this. But an ocean is a lot bigger than a lake.
