Thanks for the thoughtful, elaborate comment, Roger.

The concept of thermodynamic limits in climate processes is critical and often overlooked. It's a reminder that we need to approach these issues from a systems perspective, not just in terms of simple linear trends. The shifts you describe, especially the role of the Tibetan Plateau, should be central to any serious discussion of tipping points. You're right to point out the crucial importance of stopping emissions to prevent irreversible changes.

You should write a story about that Rahmstorf "screwed me over more than a decade ago after I made the mistake"!
