This document proposes an unprecedented global cold source regulation system aimed at addressing extreme weather driven by climate change, alongside a long-term ecological rebirth plan for Earth. The core technical framework draws on Wang Tongchun's water conservancy logic, centered on Russia's permafrost, Arctic snow belts, and Lake Baikal's low-temperature water sources, constructing a cross-regional cold source transportation network integrating land-based insulated pipelines, seaborne ice transport, and underground cold storage/ice storage facilities. Key technical details include pilot-scale design of underground cold storage (targeting 1.0×10⁶ kJ cold storage capacity), thermal-hydraulic-solid (THM) coupling simulation for permafrost-pipeline systems, low-temperature material specifications, welding technologies, and a full-cycle monitoring and control system. Complementary to the engineering scheme, the document presents an ecological rebirth roadmap spanning 100 million years, outlining Earth's natural recovery process from climate stabilization to geological equilibrium after human civilization. The plan emphasizes international cooperation, with an estimated cost of USD 80-100 trillion over 50-100 years, and verifies technical feasibility through numerical simulations, material tests, and pilot operation designs. It provides a comprehensive technical package, policy recommendations, and risk mitigation strategies, serving as a foundational blueprint for global climate action and planetary ecological restoration.
