Reviewed models and scenarios

Process

Reviewed models and scenarios: Hazard, exposure, vulnerability

In IPCC AR6 Working Group II, climate risk results from interactions between hazards and a system's exposure and vulnerability, and responses can add risk.

1. 01 Drivers

   1. 01HazardDataset · Infrastructure regulatorThe potential occurrence of a natural or human-induced physical event or trend that may harm people, property, services or ecosystems.
   2. 02ExposureDataset · Infrastructure regulatorThe presence of people, livelihoods, species, ecosystems, infrastructure or assets in places and settings that could be adversely affected.
   3. 03SensitivityDataset · Infrastructure regulatorThe degree to which a system or species is affected, either adversely or beneficially, by climate variability or change.
   4. 04Capacity to cope and adaptDataset · Infrastructure regulatorThe ability of systems, institutions, humans and other organisms to adjust to damage, take opportunities or respond to consequences.

2. 02 Assessment

   1. 05Risk from responsesComponent · Infrastructure regulatorRisks from climate responses arise when responses miss their objectives, or from trade-offs or negative side effects.
   2. 06VulnerabilityComponent · Infrastructure regulatorThe propensity or predisposition to be adversely affected. It includes sensitivity to harm and lack of capacity to cope and adapt.
   3. 07RiskModel · Critical InfrastructureRisk results from dynamic interactions between hazards and the system's exposure and vulnerability. Each may be uncertain and change.

3. 03 Response

   1. 08Risk management and responseStep · Infrastructure regulatorRisk management is plans, actions, strategies or policies that reduce the likelihood or size of adverse consequences.
   2. 09Residual riskRecord · Infrastructure regulatorThe climate impact risk that remains after adaptation and mitigation efforts. Adaptation can redistribute risk between areas and groups.

4. 04 Decision

   1. 10Decision by the responsible partyDecision · Infrastructure regulatorThe framing names no single decision maker. Decisions on responses rest with the responsible party under its own rules.

Outline of an external standard or method, from its public sources. It describes what the framework says, not a record of any run. It does not show that Nexus or any partner performs, certifies or approves a step. A gate is a step of the method, never a Nexus approval.
