World Bank Climate Change Knowledge Portal (CCKP)
CCKP provides open access to a comprehensive suite of climate and climate change resources derived from the latest generation of climate data archives. Products are based on a consistent and transparent approach with a systematic way of pre-processing the raw observed and model-based projection data to enable inter-comparable use across a broad range of applications. Climate products consist of basic climate variables as well as a large collection (70+) of more specialized, application-orientate

Useful for
- Use cases llm-inferred
- Climate-change context for FRA by extracting CMIP6 precipitation and temperature change signals for a catchment · Drainage strategy sensitivity checks using precomputed CMIP6 climate indices for future rainfall and temperature trends · Observed baseline climate summaries from ERA5 or CRU for water resources and ecology baseline reports · Population projection context (GPW v4) for water demand or catchment pressure narratives
- Audience llm-inferred
- hydrologists · flood consultants · drainage engineers · planners · ecologists · GIS analysts
Limitations
- Constraints llm-inferred
- Global grids at 0.25-degree and 0.50-degree; not UK-specific and likely too coarse for site-scale work without downscaling · Semi-annual update cadence · Precomputed, pre-processed products only; raw model output is not the offering · Accessed as an S3 bucket, not as an API or MCP server · Population data is a separate collection, not a climate variable
