Climate and Earth Systems

Climate, atmosphere, oceans, land and biodiversity are one coupled system: heat, water and carbon move between them, and a shift in one changes the hazard and exposure records of all the others. This programme covers the observation, projection, disclosure and alignment standards that let those records be read together with their provenance intact. Each artefact of these areas carries a UNI (Unique Nexus Identifier).

03System model

How a shock travels through this system

A system model of this programme built from the registry: 26 hazards, 23 systems, 10 sectors, 15 controls, 27 feeds, 18 indicators. Select the components to include, choose an initiating hazard and run the scenario. Stress propagates through the hazard relations of the Nexus Hazard Standard (NHS-1), the exposure of each system, the recorded couplings and the sectors that carry the loss; adopted standards dampen transmission and live data sources support detection. All parameters are stated assumptions that the reader can adjust; results are illustrative scenario outputs for exercises and training, not forecasts or risk assessments. The Map view places the same run on an example geography, Pacific Island states, the region of the programme’s context map, with open data: country boundaries, a grid of hexagonal cells and NASA satellite layers for the initiating hazard. The geography serves exercises and training and is not an assessment of that place.

The Global Risks Index

Every figure on this page is indexed: climate, hazards, environment, Pacific Island states.

The Index is the Consortium’s indexing system for risk data. Every indicator, hazard, series and country profile carries its Nexus Standards identifier, its source and its licence, so what this page shows can be traced, corrected and reused.

Standards

Contribute to Climate and Earth Systems

Institutions and experts are invited to charter a working group, amend an area brief or propose a data source. National participation is organised through each country’s National Nexus Consortium (NNC) and its National Working Groups (NWGs); competent national authorities are engaged through official channels.

Status and use. The Nexus Standards are proposed standards developed through an open process under NS-13 and published for voluntary use; they do not constitute certification, accreditation or regulatory approval, and adoption remains a decision of the Global Standards Council and, in each country, of its National Standards Council. A UNI (Unique Nexus Identifier) identifies an artefact; it does not certify it. Names of standards bodies and their standards belong to their stewards and are used only to identify the documents; no text of an external standard is reproduced here. Nexus Standards is not affiliated with, endorsed by or certified by any standards body named here.

Licences: CC BY 4.0 for standards text, registries, schemas and data; Apache-2.0 for reference code. External standards are cited by name, number and link under their own licences. Third-party data, libraries and fonts keep their own licences: see Third-party notices.
