I am fully aware of the concept of tipping points, having read a short story by Friedrich Schiller when I was a kid. The story introduced the concept of the butterfly effect, over 200 years ago.
If I mention tipping points as part of climate change, I get drowned out by a wailing Goethian Dies Irae chorus of deniers, calling me an alarmist.
To me, the tipping points are albedo and clathrates. What's yours?
