Primes¶
- Attractor Selection and Basin Control
- Policy interventions (carbon reduction) aim to restore the basin boundary and re-stabilize the present circulation pattern, a class of risks Lenton et al. (2008) identify in their analysis of tipping elements in the Earth's climate system.
This sourceIdentifies climate tipping elements (incl. Atlantic thermohaline circulation/AMOC) and how forcing relative to feedback timescales determines whether critical thresholds are crossed and locked in. SUPPORTS marker 057 (AMOC bistability/basin shift).

- Regime Change
- A climate regime shift occurs when the dominant mode of variability changes (e.g., from a positive North Atlantic Oscillation to a negative one) and persists for decades, a class of transitions Lenton et al. (2008) catalogue as tipping elements in the Earth's climate system.
This sourceDefinitive catalogue of large-scale climate tipping elements (AMOC, ENSO, ice sheets, monsoons), with explicit regime-shift analysis and threshold estimates for each.

- Reversibility Horizon
- The reversibility horizon lies at the tipping point, as Lenton et al. (2008) catalog in their identification of nine climate tipping elements where reversal becomes effectively impossible past threshold.
This sourceIdentifies climate tipping elements (Arctic sea ice, Greenland Ice Sheet, Atlantic thermohaline circulation, Amazon rainforest): formalizes how the rate of change relative to feedback timescales determines whether critical thresholds are crossed and locked in.

- Temporal Dynamics
- Recognition of temporal dynamics enables reasoning about critical windows, bottlenecks, phase transitions, and brittleness to timing disturbance, a class of irreversible threshold behaviors Lenton et al. (2008) document as tipping elements in the Earth's climate system.

- Threshold
- Regulatory reasoning that stops at "below threshold" misses this dynamic—a phenomenon Lenton, Held, Kriegler, Hall, Lucht, Rahmstorf, and Schellnhuber (2008) document for Earth-system tipping elements, where sustained sub-tipping forcings push slow variables across critical thresholds long after any single forcing event would appear "safe."
This sourceIdentifies the major tipping elements in the Earth-system and shows how sustained sub-tipping forcings can push slow variables across critical thresholds long after any single below-threshold forcing would appear safe.
