Maps & key findings

These pre-prepared maps, graphs and key findings are a quick way to see projections of regional changes across the UK. Information is presented on a 25km grid, and also for administrative regions, river basins and for marine and coastal areas. Select your desired region from the dropdown menu below and then choose your desired output. Additional maps may be generated from the User Interface.

Maps

These pages will give you five sets of maps showing changes for three time periods (2020s, 2050s and 2080s) at the 10%, 33%, 50%, 67% and 90% probability levels for a selected variable and emissions scenario. They are helpful for showing projected changes over time.

Map for presentations (UK Wide option only)

These pages provide three sets of maps showing changes at three probability levels (10%, 50% and 90%) and three time periods for a selected variable and emissions scenario. They are helpful for showing changes at different probability levels for a given time period.

Key Findings

These tables give the percentage change relative to the 61-90 baseline for three time periods (2020s, 2050s and 2080s) and three emissions scenarios. Values are given for the 10%, 50% and 90% probability level as well as for the lowest and highest values.

Graphs (for administrative regions only)

These graphs show projected changes for the 10%, 33%, 50%, 67% and 90% probability levels across all time periods for a given emissions scenario.

The UKCP09 projections show that in the 2080s, and under a medium emissions scenario, all areas of the UK warm on average relative to the 1961-90 baseline. Summers warm more than winters, particularly in southern England. Mean daily maximum and minimum temperatures increase across the UK in both summer and winter. Average annual precipitation changes little across the UK, but winter precipitation increases in western regions while summer precipitation decreases in many, but not all, parts of the UK. The average amount of summer cloud cover decreases in parts of southern UK. Relative mean sea levels rise around the UK but more so in southern than northern UK owing to relative land movements. Significant wave heights increase in the south east in winter and in northern Scotland in the autumn. Sea surface temperatures rise throughout UK waters while salinities decline.

Bear in mind that projections can be very different for other time periods and other emissions scenarios. It is recommended that users look at the time periods appropriate for their decisions, and examine projections for all three emissions scenarios, to gain a full appreciation of changes to which they might have to adapt.
