The flagship statement of the concept: a general definition usable across disciplines, six capacities from prevention to transformation, and a development-oriented framework that applies four drivers to five systems through a five-stage cycle of continuous improvement.
A resilience-capacity scorecard for 166 countries finds the buffers concentrated where they are least needed, weaknesses travelling together in 50 countries of 1.7 billion people, and the 2020–23 shocks felt less in the first blow than in an unequal recovery.
Development as a resilience strategy, tested on 194 countries: development capability tracks sharply lower child mortality, poverty and disaster deaths, and deficit stacks have shrunk from 3.8 to 1.2 billion people. But development does not buy stability, and it raises emissions.
Existing resilience, risk-reduction and adaptation work is organised hazard by hazard, while the risk arrives through the connections. A proposed framework defines the capacity to respond to the interactions themselves, and a six-question test to screen any action against it.
A scenario model of seven survival pathways estimates that coordinated action from 2026 could prevent about 368 million premature deaths by 2100, for roughly 1% of global GDP — and that each year of delay forfeits some 8.3 million of them.
The West’s share of world output, population and science has fallen sharply since mid-century, mostly because other regions rose. The report tests this relative-peak thesis against open data.
Galaxies, cells, airline networks and states all concentrate around a few dominant nodes. Nine original calculations show five processes build these centers, that they are efficient but fragile, and that the systems which last keep a center without depending on only one.
Do strong look-alikes turn up on every continent, and do they form one connected pattern? A proposed framework, a research programme to test it, and firm boundaries against any reading of it as human types.
Heat, polluted air and disaster cost children learning in the classroom, but the decisive harm happens at home, when a shock forces a poor household to pull a child out of school. A cohort model shows where the trap tightens and how to break it.
Has humanity passed its peak? Dating eighteen indicators, the report finds no single summit: capability keeps compounding while fertility, institutional trust, shared culture and ecological stability peaked decades apart.
The flagship statement of the Polycrisis Apocalypse thesis: ten coupled pressures, ranked by how many people they reach, and nine original calculations showing when thin buffers turn separate shocks into compounding, persistent harm.
Why do unrelated people look alike? Using one consenting reference subject, the report traces recurring resemblance to four interacting layers — genetics, developmental constraint, probability and perception — and sets out a pre-registered test.
Does the fractal geometry shared by lungs, rivers, clouds, galaxies and cities reveal a unifying architecture? Ten original calculations find the unity is real, but it lies in processes rather than shapes.
Is mathematics merely a language for describing reality, or does its unreasonable effectiveness reveal something about reality itself? Seventeen original calculations, and a conditional answer.
Civilization as a race between two capacities usually treated as one: the capacity to produce complexity, and the capacity to manage its consequences. It lasts only while the second keeps pace with the first.
The culminating synthesis of the Architecture of Creation series. Reality’s complex systems are not built by one mechanism, but they are built under one set of constraints and must solve one set of problems.
Venus, Earth and Mars began with the same ingredients. Only Earth kept liquid water for four billion years. Habitability as an emergent property of coupled systems — maintained, not given.
How chemistry could have become life, how life then built its many levels of organisation, and whether the same principles of construction recur from molecules to the biosphere.
How the universe built complexity out of simple beginnings, and whether the same structural principles recur at every stage — the Architecture of Creation framework taken to the largest domain available.
What the second law can and cannot tell us about the loss of organised structure in civilisations, ecosystems and the Earth system. The mirror image of The Architecture of Creation.
Where Survivability Risk Regions are, who will live in them as the demographic centre shifts, and what an exposure integral over 48,000 years implies. Third in the Polycrisis Apocalypse line, after HH-2026-24 and HH-2026-33.
A second, Global Risk & Earth Systems edition of the Polycrisis Apocalypse framework — reframed around the gap between survival and sustainable survival, and followed through centuries, millennia and deep time. Supersedes HH-2026-24.
Flagship report in the Architecture of Creation series. Can the architecture that lets a civilization emerge, expand and dominate also explain how it loses coherence? For Europe, a qualified yes.
Flagship report. The mathematics of diffusion — first written down for salt dissolving in water — as a disciplined way to see technology spread, productivity convergence and the accumulation of capability whole.
Why unrelated people sometimes look alike, and what that reveals about how a shared genetic and developmental architecture generates human form. A conceptual synthesis and research proposal.
Why the same forms recur across unrelated systems — spirals, hexagons, branching networks, streamlined bodies — and what the constraints, generators and filters behind them have in common.
Decisions this decade, consequences to 2100. A purpose-built scenario model compares four futures and finds that acting early and together could avert roughly 368 million deaths — while delay or siloed action forfeits more than a third of that. Report 01 of the Polycrisis Resilience series.
An evidence review of the “Western collapse” thesis — population decline, immigration, ethnic change and social cohesion — with scenarios to 2075.
How the demographic centre of humanity is moving into the planet’s most climate-exposed regions, and what it will take to keep the late twenty-first century liveable. Part II of the Century Recalibration series.
Where is humanity headed by 2100? The demographic shift toward Africa and South Asia, the ageing of the West and East Asia, the convergence of the Asian century, and the polycrisis — and what life will be like for the median human at the end of the century.
A name for the worst way the polycrisis could end — and a framework for keeping it hypothetical. The decisive variable is the race between the rate crises add stress and the rate institutions repair it.
Nodes, channels, amplifiers and circuit-breakers, with the 2026 Strait of Hormuz crisis as a live case.
Why the central development problem is no longer invention but delivery.
The case for accelerating development is usually moral and economic. This report adds a third argument — timing: several slow stresses are set to peak together between 2040 and 2060, and development cuts vulnerability far faster than mitigation cuts hazard.
How air pollution, heat, hunger and poverty harm the body and mind, how feedback loops make the suffering self-reinforcing, and why it will be prolonged for centuries in the regions where survival is most at risk.
How many people the entangled crises of the century could kill, who is most exposed and vulnerable, and how much of the toll is avoidable: measured evidence, a transparent scenario model and an honest account of the catastrophic tail.
Debate about technology and development is usually conducted in the future tense. This report looks at what has already happened — which innovations reached the rest of the world, how completely, and what the record teaches about how diffusion works.
Resilience finance is scarce and barely correlated with vulnerability. Scoring 122 economies on risk intensity, risk mass and deliverability to show where each dollar would do the most.
How climate change, pollution, and ecosystem degradation compound each other — and where three pillars of resilience should intervene.
What protects health, security, connection and hope when climate, economic, conflict, health and information risks arrive together — the evidence, the four layers of protection, and a ten-year path.
Why the investments that lift people up are the same investments that stop shocks from spreading.
Climate, pollution and instability act on the same people at the same time. A five-layer Capacity Stack for anticipating, absorbing and adapting to all three at once — and why capacity built early is cheaper than capacity improvised.
Why risks now travel together, how shocks cascade through coupled systems, and what governments, firms and communities can do to keep functioning — the evidence, a framework and a roadmap.
How shrinking the number of people in harm’s way, loosening the links between failing systems, and enlarging financial and institutional buffers can reduce the human cost of coupled global crises.
Demography, Asia and Africa’s rise, technology and AI, climate, pollution and biodiversity, geopolitics, and whether progress can outpace systemic risk: a forward analysis to 2100.
Which places are most likely to keep sustaining human health, stability and prosperity as climate, resource, demographic and governance stresses arrive together? A Habitability Resilience Index for 175 countries — and a demographic mismatch at its centre.
Why 2027 is the year the slow variables and the fast shocks arrive together, and what that means for those who must prepare.
A transparent 0–100 index of national capacity to reduce, absorb and adapt to compound risk — 40 countries, 18 indicators, six pillars, projected to 2100 under four IPCC pathways.
How much of humanity will live for decades with a shrinking margin for error, and where? A Survivability Exposure Index across seven world regions, set against each region’s adaptive capacity.
Adaptive capacity is the meta-capability that decides whether a shock becomes a contained disruption or a cascading crisis. It runs on two engines — infrastructure and institutions — that must be built together.
One asset class cuts seven coupled threats at once. The obstacle is not technology or cost but an appraisal system that credits a single benefit and prices none of the harm.
Systemic vulnerability is built, not given. Two levers — adaptation and clean infrastructure — can lower it, but only if they are financed and sequenced before the concrete is poured.
Coupled shocks defeat siloed responses. Four mutually reinforcing pillars — climate resilience, development finance, the energy transition, and institutional capacity — form a single strategy rather than a menu.
No reports match that filter.
