United States 2026
Stati Uniti
The United States enters 2027 as the country carrying the largest share of the world’s recorded disaster losses. North America accounted for US$133 billion of the US$224 billion in global natural-disaster losses in 2025, about 70% of it insured, led by the Los Angeles wildfires at about US$53 billion.

01 · Readings
United States in six readings.
Six readings that frame the baseline, and the eight questions this edition answers, each with its status and source.
02 · Sectors
Six sectors, one hexagon.
Water first, then Energy, Infrastructure, Food, Health and Biodiversity. Each count is the findings of this edition in that sector: coverage of the evidence, never a score. Infrastructure is not assessed: the edition holds no Infrastructure finding and its coupling matrix does not assess it.
- WATAcqua2 findings
322 bn gal/day Total freshwater and saline withdrawals, 2015. □Dichiarato
Ample in the East, tight in the West; Colorado River under carenza; major aquifers depleting.
- ENEEnergia1 finding
4.4% Data centres’ share of US electricity, 2023. □Dichiarato
Gas-led power with growing renewables; reliability stressed in extremes; data-centre load rising.
- INFinfrastrutturenot assessed
Ageing grids, water sistemi and roads; critical functions defined nationally.
- FOOCibo1 finding
13.5% Households food insecure, 2023. □Dichiarato
A leading producer and exporter; 13.5% of households food insecure in 2023.
- HLTSalute1 finding
2,325 deaths Heat-related deaths, 2023. □Dichiarato
Record heat deaths in 2023; smoke and storms load health services.
- BIOBiodiversità1 finding
40% Animal species at risk of extinction, 2023. □Dichiarato
About 40% of animal species at risk; incendi boschivi and land use the fastest pressures.
Outside the six sectors: Climate forcing 3, Finance 2, Systemic 1.
03 · Hazard exposure
The hazards this edition reads.
The edition’s own risk objects, in its order, each read across driver, exposure, vulnerability, capacity, cascade and horizon. The hexagon marks the sectors the cascade reaches; the domain beside each is an editorial reading of its hazard words.

Scenario · SCN-USA-HFG-01
Western heat, fire and grid summer
Under this scenario, results describe a conditional season under stated assumptions. It is not a forecast, and no intervention described here has been carried out.

04 · Couplings
How the sectors carry risk into each other.
The United States matrix types the twenty couplings between the five core sistemi. Strengths are Nexus estimates from the cited evidence and analogue events; they set the starting graph that the Q1 2027 Foundry cut will test.
| Da | WAT | ENE | FOO | HLT | BIO |
|---|---|---|---|---|---|
| WAT | · | Strong | Strong | Moderato | Strong |
| ENE | Moderato | · | Strong | Strong | Moderato |
| FOO | Moderato | Weak | · | Strong | Strong |
| HLT | Weak | Weak | Moderato | · | Weak |
| BIO | Strong | Moderato | Strong | Moderato | · |
Water: 4 couplings out, 4 in; Energy: 4 couplings out, 4 in; Food: 4 couplings out, 4 in; Health: 4 couplings out, 4 in; Biodiversity: 4 couplings out, 4 in. Infrastructure is not in the coupling matrix: none of the edition matrices types it, so it carries no value.
