Final December, the UK Atmosphere Company up to date its Nationwide Flood Danger Evaluation (NaFRA), exhibiting present and future flood danger from rivers, the ocean and floor water for England.
It used its personal information alongside that of native authorities and local weather information from the Met Workplace.
It additionally introduced updated the Nationwide Coastal Erosion Danger Map (NCERM). They had been each final up to date in 2018 and 2017 respectively.
The brand new NaFRA information reveals as many as 6.3 million properties in England are in areas vulnerable to flooding from rivers, the ocean or floor water, and with local weather change this might enhance to round eight million by 2050.
