Global climate model projections for the CMIP5 RCP8.5 emissions scenario produced as part of the UK Climate Projection 2018 (UKCP18) project. Data has been produced by the UK Met Office Hadley Centre, and provides information on changes in 21st century climate for the UK, helping to inform adaptation to a changing climate.

The set of 28 projections is a combination of 15 coupled model simulations produced by the Met Office Hadley Centre, and 13 coupled simulations from CMIP5 contributed by different climate modelling centres.

This data set provides information on changes in climate across the entire globe from 1900 to 2100 for RCP8.5. Each projection provides an example of climate variability in a changing climate, which is consistent across many climate variables at different times and spatial locations.

This dataset contains regional averages for 16 administrative regions across the UK.

Citable as:  Met Office Hadley Centre (2018): UKCP18 Global Projections by Administrative Regions over the UK for 1900-2100. Centre for Environmental Data Analysis, date of citation.

UKCP18 Climate Realisations for UK Administrative Regions from Global Projections


Climate model simulations made using the HadGEM3 model. The uncertainties in the projections of future climate are represented by the spread of the perturbed multi-model ensemble.
