Hazard layers awaiting licence review
Each layer appears here when counsel admits its source for these pages. Until then no value from it is shown.
| Hazard layer | 来源 | Why it waits |
|---|---|---|
| Tropical cyclone tracks | IBTrACS, NOAA NCEI | Published for research; commercial use is governed by WMO Resolution 40 and is not confirmed for these pages. |
| River flood hazard (return periods) | JRC global river flood hazard maps | The register records the release terms as unconfirmed (legal review required). |
| Seismic hazard | GEM global seismic hazard map | Expected to be non-commercial; legal review required. |
| Earthquake catalogue | USGS earthquake catalogue | Public domain with acknowledgement requested; the register row is under legal review. |
| Landslide susceptibility | NASA LHASA | NASA data policy places no restriction on use; the register keeps NASA sources under legal review. |
| 活跃火点 | NASA FIRMS | Live data reaches these pages only through NXS-GRX (canonical data, provenance and risk), once admitted. |

状态
The Global Risks Index 的方法、结构和定义为预备性工作草案（2026），供审阅和评论，不供实施。在从受治理的证据截取中发布版本之前，不会出现任何数值；届时数值将附有区间、类别、来源及其更正途径。模拟器以您选择的数字运行已发布的方法，绝不显示 NXS-GRX 数值。
NXS-GRX 不是什么
NXS-GRX 是研究和风险分析信息。它不是信用评级或 ESG 评级，不使用任何评级尺度；它不是金融工具的基准，不是官方统计，不是紧急警报或官方分类，也不是建议。不得用于评估自然人。风险等级是已发布尺度上的区间，绝不是对国家或个人的排名。
机构与来源
The Nexus Consortium is stewarded by three independent not-for-profit institutions: The Global Centre for Risk and Innovation (GCRI), through GCRI US in Washington, DC and GCRI Canada in Ontario, with GCRI Canada as Lead Institution, Consortium Secretariat and lead contracting organisation; The Global Risks Forum (GRF); and The Global Risks Alliance (GRA). Technology, infrastructure and service providers work with the Consortium at arm’s length under written agreements, like every other external party in the public-private-planet model, and hold no role in its stewardship.

Avis en français
La méthodologie et les définitions du NXS-GRX sont un projet de travail préparatoire (2026). Le NXS-GRX est une information de recherche et d’analyse des risques : ni notation, ni indice de référence financier, ni statistique officielle, ni alerte, ni conseil. Les classes de risque sont des bandes sur une échelle publiée, non des classements.
