The Earth’s climate is changing. Global temperatures are predicted to continue rising, bringing changes in weather patterns, rising sea levels and increased frequency and intensity of extreme weather for the UK. The extent of change will depend greatly on how successfully the world cuts its greenhouse gas emissions.

We need to understand how our climate might change so that we can prepare. Organisations need good evidence, which includes a measure of the uncertainties involved, to help them consider the risks that a changing climate might pose and plan what they should do to increase resilience and reduce those risks.

The UK Climate Projections 2009 have been developed to do this.
