New climate report warns of London flooding risk

The risk of London flooding by 2100 will be significantly higher than current projections, according to climate scientists.

A new report “From Ice to High Seas”, which was co-ordinated by the British Antarctic Survey, claims melting polar ice will lead to sea level rises of up to 69cm, with a 5% chance it could rise as much as three feet. In the worst case scenario, that would see the Thames Barrier breached every 12 years.

Previous projections published in 2007 estimated rises of up to 59cm, that’s 10cm lower than the latest projection. If either of these two findings come true, the Environment Agency predicts we could see one-in-a-thousand-year storms occurring every decade.
