Using Climate Projections

Plant Image

The UK Climate Projections (UKCP09) website is the leading source of climate information for the UK and its regions. It is designed to help users with the process of adapting to a changing climate.

The climate projections were created with a range of uses in mind. How you use UKCP09 will depend on what you are planning to use them for. To find the most appropriate information for you please see the What do you want to do? page.

Before you start using the climate information provided on UKCP09, we recommend that you familiarise yourself with the guiding principles set out in Before you start using UKCP09..., Probability in the UKCP09 projections and Handling uncertainty in UKCP09 pages. These can be accessed using the menu on the left of this page.

Using UKCP09

UKCP09 provides three types of climate information:

1)  Observed climate data: historical climate data on variables including temperature, rainfall and snowfall, storminess, sea-surface temperature and sea levels, since 1900.

2)  Climate change projections: future projections for variables such as temperature, rainfall and snowfall, air pressure, cloud and humidity; and

3)  Marine & coastal projections: future projections for sea level rise, storm surge, sea temperature, salinity, current and waves.

UKCP09 provides climate projections for the UK for three different future greenhouse gas emissions scenarios: a low emissions scenario, a medium emissions scenario and a high emissions scenario.

There are three principal ways of accessing climate information in UKCP09

1) The Maps & key findings section provides maps, graphs and key findings that show snapshots of climate projections for the UK at the national and regional levels. They provide a quick way to see projected changes in the UK climate.

2) Published reports are available in the Reports & guidance section.

3) The User Interface  provides advanced users the opportunity to set their own parameters for data variables and generate customised output graphs and charts, maps or raw data.
