Released maps

Maps of Climate and Hazards are published here once their data rights are cleared and they have been reviewed. Each shows its time and space reference, its sources and its uncertainty.

01In brief

The short answer.

Climate and Hazards released maps are reviewed map views of climate and hazards, published once their data rights are cleared, each with its coordinate reference, date, sources and uncertainty. Layers draw on sources such as ERA5 reanalysis (Copernicus Climate Change Service, ECMWF). A map shows released, rights-cleared evidence, not a live feed or an official warning.

For released maps, in GCRI's spatial-intelligence reading, the map opens on active fires, population density, flood water and true-colour imagery with relief in 3D, framed on World; 2 further NASA layers wait in the list.Satellite and model products as NASA publishes them, each with its own date; indicators, not assessments of any place; claim ceiling INTEGRATED.

06Reading the maps

Cautions that apply to hazard maps.

Hazard maps show probability of the hazard, not risk; exposure and vulnerability are separate layers.
Return-period maps rest on records that may be non-stationary.
Projected change maps depend on scenario and period; both are stated.
Global hazard maps are too coarse for site decisions.

07Status

Releases appear as they are reviewed.

Analysis runs in Nexus Foundry; reviewed releases are listed here.

08Key terms

Terms used on this page.

Each term as this page uses it. Where a standard-setting body defines the term, the wording follows that body.

Term	Definition
Coordinate reference system	The definition that ties coordinates to locations on Earth, catalogued with EPSG codes.
Modifiable areal unit problem	The change in statistical results that comes from how areas are drawn and aggregated.
Zonal statistics	Statistics of raster values summarised within boundaries such as districts.
Public-safe release	A recorded decision on the detail at which a layer may be published without exposing sensitive sites or people.
