The century is not a collapse. It is a survivability regime.
Climate, pollution, water, grid, demographic and institutional pressures do not arrive separately — they synchronize. This resource maps where they couple, who sits inside the buffer versus the chronic-risk envelope, and what remains mitigable.
Not uniform collapse. Not a return to the Holocene. A stratified settle.
The dominant outcome this century is neither civilizational collapse nor restoration of a stable climate. It is a survivability regime: a buffered zone with managed heat, power and air, surrounding a chronic-risk envelope where months of functional exposure erode labor, cognition and learning.
The decisive variable is not temperature alone — it is absorptive capacity: whether finance, grid, cooling and institutions compound into installed stock before the curves sync. Mitigation here is navigation, not reset.
The concerns we track
Pollution, climate, heat, inequality, demographics, cybercrime and their downstream cascades — each has its own dashboard, but none stands alone. They share drivers and amplify one another.

The Human Century Problem Index
Twelve century-scale problems scored across six dimensions and ranked by coupling — what drags the most systems down at once.

Pollution, climate, heat, inequality, demographics, cybercrime and cascade effects — the data behind each pressing issue, explorable side by side.
Open the dashboards → MitigationFive levers, applied to the cores
Path, Stock, Medium, D and Allocation — what is actually mitigable for each Tier I problem, and what is beyond control.
Read the framework →The systemic cores
Highest coupling-weighted scores. These problems drag the most systems at once. These five rank highest because they break grids, schools, farms and finance at once — coupling and medium-impact, not headline severity, drive the score.
| # | Problem | HCPI | Why it ranks here |
|---|---|---|---|
| 1 | Development & D trap | 8.7 | Adaptation competes with growth; LMIC convergence stalls |
| 2 | Institutional fracture · conflict | 8.6 | War and state failure destroy D overnight |
| 3 | Chronic heat & humidity envelope | 8.4 | Billions face months of functional heat exposure |
| 4 | Grid · power · compute thermal | 8.4 | Cooling demand, blackouts, throttled compute |
| 5 | Stratified buffer allocation | 8.3 | Who gets cooling, filtration, power, relocation |
The shape of the century
Layering
Crisis curves rise but rarely sync. Cognitive/pollution exposure already near-universal; functional heat episodic. The cheapest decades to install stock.
Danger window
Heat, water, grid, demographic and institutional curves synchronize. Trajectories bottleneck or fork here — the decisions that lock in buffer vs envelope.
Stratified settle
Outcomes resolve into a survivability regime: buffered zones with managed heat, and a chronic-risk envelope of months-long functional exposure. Not uniform collapse, not restoration.
