04Regional frame

Where regional cooperation on hazard happens.

Regional climate centres, regional climate outlook forums and downscaling programmes such as CORDEX provide the regional layer between global models and national services.

  • WMO Regional Climate Centres and outlook forums.
  • CORDEX regional domains.
  • Regional seismic and tsunami networks.

Process

Regional subject applications: Policy question to decision

A priority becomes a question, evidence, a decision case and a limited publication; the competent authority decides, never the programme.

  1. 01 Question

    1. 01A priority becomes a questionStep · Universe; national counterpartsA priority becomes a researchable question with stated criteria. National counterparts own the agenda, data and decisions.
    2. 03Scientific and stakeholder challengeStep · the Global Centre for Risk and Innovation (GCRI); the Global Risks Forum (GRF)Scientific and affected-stakeholder challenge informs mission selection and methods.

  2. 02 Evidence and options

    1. 04Assemble the evidenceStep · GCRIMethods, labelled data and uncertainty are assembled. Every finding carries one of nine evidence labels.
    2. 06Decision case with optionsRecord · The decision owner named in the caseA decision case binds owner, alternatives, evidence and deadline. It needs sensitivity and robustness.

  3. 03 Review and publication

    1. 07G6 · Publication authorisedGate · The Global Risks ForumGRF authorises publication of results that have passed scientific and editorial review. It cannot publish personal data.
    2. 08Publish with method, uncertainty and limitsRecord · ReportsFindings are published with their method, uncertainty and limits. An edition is published after review, not to a calendar.

  4. 04 Outside the programme

    1. 02Competent authority decidesDecision · The competent authorityThe authority or institution decides under its own rules. The authority decides; the programme informs.
    2. 05Action and implementation stay with the ownersActor · The relevant government, operator or licensed institutionDecisions and execution stay with the relevant government, operator or licensed institution. The programme records one only if shared.

  5. 05 Learning

    1. 09Corrections and lessons feed the next agendaStep · UniverseCorrections and lessons feed the next annual agenda. The findings of one year set the mandate of the next.

The Nexus cycle · Decision rights · The programme yearDesigned programme process, not a record of operation. No cycle has run and every programme is at service level R0. A gate is a programme decision, never a public-authority approval, certification or deployment authorisation.

06Status

Work is shown as its record stands.

Programmes are listed as exploring, forming, constituted, active, paused or archived. Country and regional entries appear when a programme record supports them.
