Britain's Most Extreme Weather

Alex Beresford looks to the past and analyses the latest scientific studies to find out if rainfall in Britain is getting worse. In Worcester in 1770, flood levels reached 15.5 metres - a record that stands to this day - while in 1872, coffins were exhumed by heavy rain in Manchester. With the Thames and Severn bursting their banks during the winter of 2013-14, Alex asks whether the nation is any more prepared for wet weather now than it was hundreds of years ago.
