"Around eight million properties in #England - or one in four - could be at risk of #flooding by 2050 as the danger increases due to #CimateChange, the Environment Agency (EA) has said.
The number could be even higher if more houses are built on floodplains, but could be lower if flood defences are improved.
Currently, 6.3 million properties are considered at risk from flooding, new figures show, which is higher than previously thought."
