Climate change is applied the displacement framework: S0_Earth is the Holocene climatic envelope; D(xi_climate) is measured across temperature, CO2, ocean pH, ice coverage, and biodiversity. Tipping points (Arctic sea ice, Amazon, permafrost, WAIS, AMOC) are formalized as wrong attractors with self-sustaining feedbacks. A critical threshold D* (~1.5-2C warming) marks where the return gradient reverses.
Phi_Earth = accumulated planetary displacement since industrialization. Mitigation reduces dD/dt; adaptation manages current D; geoengineering attempts to shift S0. The Tipping Cascade Theorem formalizes the risk of cascading wrong attractors toward Hothouse Earth.
