What is the Independent Assessment of UK Climate Risk (CCRA3)?
The UK Government is required, under the 2008 Climate Change Act, to publish a Climate Change Risk Assessment (CCRA) every five years which is published on the Government website. The assessment sets out the risks and opportunities facing the UK from climate change.
The Climate Change Committee is working on an independent advice report, due to be published in June 2021, which will inform the UK Government’s third CCRA (known as CCRA3). This website will host all of the outputs for the UK Climate Risk Independent Assessment (CCRA3), from a technical report through to the research projects through to summaries of the advice. The UK Government and devolved administrations must then set out their response to the risks and opportunities in their national adaptation programmes.
Climate change in the UK
Adaptation is needed alongside global mitigation to manage the risks and opportunities from climate change in the UK. The climate has already changed, and further change is inevitable. How much climate change the UK experiences after 2050 is uncertain and will be dependent on global emissions reductions.
The average annual UK temperature is around 1.2°C warmer than the pre-industrial period.
Twice the likelihood
of a hot summer
The chances of experiencing hot summers like in 2018 have doubled in recent decades and are now about 10-25% per year. This will rise to 50% by 2050, i.e. on average, every other summer will be as hot or hotter than 2018
Rise in sea level
UK average sea level has risen by 16cm since 1900, and will continue to rise for centuries due to time lags in the climate system.
