5.1Assumptions

Scenario SCN-ARE-HTW-01: what is assumed, and what is held constant.

Baseline
the 2026 reference state in this edition
Drivers
a hot, humid summer fortnight with record cooling demand, after a spring heat reading like that of May 2025
Analogues
May 2025 heat25; April 2024 rain23 (a different hazard, used for response only)
Interventions
none modelled: the specification describes the unmitigated case
Run state
narrative specification; quantified Foundry run scheduled for Q1 2027

5.2The cascade, step by step

  1. 1

    CLI → ENE

    cooling load raises peak power demand

    summer peak

  2. 2

    ENE → WAT

    desalination needs power at the same peak

    system link

  3. 3

    CLI → HLT

    heat load rises on outdoor workers around the midday break

    break rules26

  4. 4

    WAT → HLT

    water for drinking and cooling is stretched

    system link

  5. 5

    HLT → INF

    care and transport capacity are stretched

    system link

  6. 6

    FIN

    costs fall on utilities and the public budget

5.3The scenario as a table of steps

How the shock in scenario SCN-ARE-HTW-01 would travel through United Arab Emirates’s coupled systems, step by step, under the assumptions the edition states.
