Key findings for sea level rise

The key findings for UKCP09 are a quick way to see projected changes in the UK climate at a national and regional level. They use the three UKCP09 emissions scenarios, and a range of probability levels to show the spread of possible outcomes.

Use the key findings to:

• communicate the main results of UKCP09;
• raise awareness about climate change;
• consider climate changes at a national or regional level; and
• introduce the concept of probabilistic climate projections.

The table shows central estimates for each decade of relative sea level changes (cm) with respect to 1990 levels.

The H++ scenario mean sea level estimate for around the UK is 93 to 190 cm, but please note that the top of the range is very unlikely to occur in the 21st century.
