As large parts of the UK continue to be affected by flooding, there is a warning that the weather could get worse over the next 20 years.
The Committee on Climate Change says that four times as many homes and businesses could be at risk unless the UK prepares for more extreme weather conditions.
The government says it is spending more than £2bn on reducing flood risks.
