Discontinuous effects, yes.

A stable climate functions more like a light switch than a dimmer switch. There is an "off", and once we go there getting back is really hard. It's almost like a one way switch.

As one example of a feedback loop, when polar ice melts, the area effectively turns from white (ice) to black (ocean). This area then absorbs more heat, driving more heating. So that's one feedback loop.

I think the feedback loops are kind of cool to study. Methane emissions in the tundra. Greenland melting causes more melting. Higher temps cause more water vapor that absorbs heat.

That doesn't give you specifics on where the line is. But wanted to give you an idea about the discontinuity, that there is a threshold vs dimmer switch.

P.S. I plugged your question into ChatGPT but the response was vague.
