Nonlinear Climate Stability, CO₂ Gradient Dynamics, and Planetary Analogues: A Systems-Level Framework

Description:

This work presents a comprehensive nonlinear-systems analysis of Earth’s climate, introducing the hypothesis that the rate of increase of atmospheric CO₂ (the gradient dCO₂/dt) is a critical stabilizing driver of the current climatic attractor. Contrary to traditional models that focus primarily on absolute CO₂ concentration, this study argues that a sudden stabilization of CO₂ levels—without any reduction—may trigger a large-scale reorganization of the climate system as it seeks a new equilibrium. Such bifurcation events are well documented in nonlinear physics and paleoclimate transitions.

The extended framework integrates multiple layers of Earth and astrophysical dynamics, including:

• the geometry-driven asymmetry of the American continents and its role in Gulf Stream formation,

• AMOC sensitivity to thermohaline perturbations,

• Earth’s internal energetics and magnetic field generation,

• Venus and Mars as planetary analogues of runaway vs. collapsed climates,

• the Sun’s vertical oscillation through the Galactic plane,

• and the recent increase in detected interstellar objects (ʻOumuamua, Borisov, 3I/ATLAS) as potential markers of changing galactic environment.

By combining atmospheric physics, nonlinear dynamical systems, geophysics, planetary science, and astrophysical boundary conditions, the paper proposes a unified perspective on climate stability and civilizational risk. It argues that emerging climate bifurcation risks may exceed the modeling capacity of conventional tools and may ultimately require AI-augmented global governance frameworks to ensure safe long-term stewardship of Earth’s systems.

The document is written as a research-style preprint and is suitable for scientists working in climate physics, nonlinear dynamics, complex systems, planetary climatology, and global risk assessment.
