UK Wide

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.
