Climate-conditioned hazard catalogues
Stochastic event sets for a peril are adjusted to reflect current or projected climate, using reanalysis trends and climate model ensembles, and the change in modelled loss is reported as a scenario.

Climate and atmospheric science explains how the hazards that drive pérdida asegurada are changing: storms, floods, heat, drought, incendios forestales and sea level. On this platform it supplies the hazard evidence and scenarios on which catastrophe models, stress tests and insurability studies are conditioned, with their uncertainty.
Climate science studies the physical processes that govern the atmosphere, oceans, cryosphere and land surface over seasons to centuries. It provides the basis for understanding changes in hazard frequency and intensity that propagate through economic and social sistemas. In insurance and catastrophe, climate and hazards and health and biosecurity, climate projections frame long-horizon scenarios for infrastructure, insurance, food systems and public finance. They allow correlated hazards across regions and sectors to be examined together. The canonical description is on el bien común CTIM.
Stochastic event sets for a peril are adjusted to reflect current or projected climate, using reanalysis trends and climate model ensembles, and the change in modelled loss is reported as a scenario.
Physical risk scenarios for stress tests are built from NGFS scenarios and emission pathways, translated into hazard changes by region and peril, with every assumption documented.
Reanalysis, radar and satellite observations give rapid event footprints that support claims triage and the index measurements on which parametric payouts depend.

Models are evaluated against observed climatology, historical trends and paleoclimate records. Multi-model comparison and process-based diagnostics expose structural differences.
| Verificación | Cómo se hace |
|---|---|
| Historical reproduction | Conditioned hazard catalogues must reproduce observed hazard statistics in the calibration period before any projection |
| Ensemble spread | Results are reported across climate models and scenarios, never from a single model |
| Downscaling validation | Regional hazard from downscaled projections is compared with local observations before it enters a loss model |
Projections depend on emission pathways and on parameterised processes such as clouds and convection. Regional detail and changes in rare extremes carry wide uncertainty.

En los seis pilares, bajo la dirección de Nexus Consortium
Assembled from the Nexus Standards area profile Seguros y reaseguro: the shocks it names, the sistemas and sectors that carry the loss, the controls that dampen it and the data that observe it. Pick an initiating shock and step through the cascade to see which exposures it reaches and where losses could concentrate. The Map view places the run on an example geography with open data. Every weight is a stated assumption. An exercise, not a forecast, a valuation, a rating or investment advice. To model a place of your own choosing, open the full Constructor de sistemas.
