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.

Process overview

This dataset was generated by the computation detailed below.

UKCP18 Global Projections


The data is provided at 60km resolution, the native resolution of the 15 Met Office Hadley Centre projections.

The CMIP5 projections have been regridded to this resolution. The Met Office Hadley Centre projections are all variants of the global coupled models HadGEM3-GC3.05, differing only in the choice of values assigned to 52 model parameters that control the strength of processes that affect the climate system and how it responds to anthropogenic emissions. The set of parameters to perturb was chosen by expert elicitation. A subset of these HadGEM3-3.05 projections were used to drive the UKCP18 Regional Projections.

The model is configured to run using a N216 Gaussian grid which has a 60km resolution over the UK.
