This Guardian long-read by Gaia Vince (Aug 2022) documents the coming “century of climate migration,” citing large-scale displacement projections (up to c.1.2 billion by 2050) and examples of uninhabitable regions, extreme heat, fires and floods, and argues for planned, humane, justice-centred migration policy and investment in resilient infrastructure; it is included in PART 1, chapter “Your Capital And the Power of Generosity” because the piece supplies urgent, evidence-based rationale for the book’s call to mobilise all forms of capital—treasure, time, talent, ties and testimony—toward strategic giving, investment and policy engagement that protects displaced populations, builds community resilience and treats migration as a managed solution rather than purely a crisis.
