A tipping point isn't gradual decline — it's a stable system that holds steady right up until forcing crosses a threshold, then flips abruptly to a new stable state.
dX/dt = forcing - resilience*X + X^3 (bifurcation form)
irreversible once past threshold
- Grid resolution — sub-regions of the tipping system tracked independently.
- System resilience — how much buffering capacity keeps the system in its current stable state.
- Warming forcing — cumulative warming pressure pushing the system toward its threshold.
- Recovery rate — how fast (if at all) the system could recover once forcing eases — often near-zero once tipped.
The West Antarctic ice sheet, Amazon dieback and AMOC slowdown are all real candidate tipping points scientists monitor for exactly this kind of threshold behaviour.
