The impact of a changing climate on the severity of flooding has been demonstrated in the largest-scale study of its kind – with parts of northern Britain seeing the largest increase in Europe. The multinational study, which included the Centre for Ecology & Hydrology, looked at river flow data from thousands of locations over a 50-year period and found that flood events are becoming increasingly severe in north-western Europe, including the UK, but decreasing in severity in southern and Eastern Europe.
