Okay so what this is called is a tipping point, and it sucks.

Sigh.
See, this is what we were trying to avoid. And maybe it was inevitable, maybe even before I started doing this, before I became an adult, even before I was born this was predestined to happen.
But I and people like me were trying to prevent things like this, like the permafrost methane being vented, like Greenland melting, etc. And now its a mix of guilt and distress. Distress because we failed, guilt because it was our job to work to prevent it and we're failing. And our grandchildren are going to despise us for it.
