01 · Status

Status and boundaries.

This edition governs nothing and confers no certification. It records where the evidence stood at the 2026 baseline. Every value resolves to its source or to its stated method; where neither exists, the edition says so instead of filling the gap.

02 · Key messages

What the edition finds.

Five of the questions the edition answers, each with its status. The executive summary has all of them, with their sources.

  1. Gross emissions were 6,343 Mt CO₂e in 2022; net emissions about 17% below 2005.

    Where do emissions stand?報告値

  2. 27 billion-dollar disasters in 2024; the 2025 Los Angeles fires were the costliest 林野火災 on record.

    Are disaster losses rising?報告値

  3. About 70% of 2025 North American losses were insured, but cover is retreating where risk is highest.

    Who carries the losses?報告値

  4. Heat with drought and fire, through grids, water, health and insurance.

    Which hazard couples the most システム?Inferred

  5. Winter Storm Uri in 2021 showed cold can fail power, water and health together; summer peaks now add data-centre load.

    How exposed is the grid?報告値

All key messages and the headline finding

03 · Contents

Eight chapters and three annexes.

  1. ·

    Executive summary

    The edition on a few pages: the abstract, the key messages, the headline finding and what each steward reads in it.

  2. 1

    Chapter 1. America’s risk is coupled, not cumulative

    Part I describes システム and their couplings.

  3. 2

    Chapter 2. Key findings

    Twelve findings carry the baseline. They are grouped by system, never ranked.

  4. 3

    Chapter 3. Systems and sectors at baseline

  5. 4

    Chapter 4. Risks and capability

    Four risk objects open the portfolio. Order carries no rank.

  6. 5

    Chapter 5. Western heat, fire and grid summer

    A conditional statement under stated assumptions, never a prediction.

  7. 6

    Chapter 6. Readings from the other desks

    The baseline is read through each steward’s lens, then once as a whole.

  8. 7

    Chapter 7. The 2027 agenda

    Eight bounded questions open the 2027 National Agenda.

  9. 8

    Chapter 8. Systems in depth

    One section per system: its state at evidence close, its exposures and what the operational series will watch.

  10. A

    Annex A. Methodology

    How the edition was made: methods, the model card, the evidence cut and its age, the acceptance record and the glossary.

  11. B

    Annex B. Data appendix

    The indicator set with its sources, the source registers, the licences of every kind of material and the formats of the edition.

  12. C

    Annex C. References and record

    Every source the edition rests on, the publication record, the corrections log and the open record.

04 · GCRI reading

How GCRI reads this edition.

The evidence supports a coupled reading of American risk. Losses are rising with frequency; the grid couples heat and cold to water and health; and insurance is retreating where risk is highest. Evidence is strongest for losses and emissions, and weakest for state-level insurance availability and cross-system dependencies.
