Areas of London that will be affected by floods in the future

After last weekend’s violent thunderstorm, we all saw how vulnerable some areas in London are to floods. Residents of Walthamstow, Hackney Wick and Camberwell found stations submerged and local roads turned into rivers.

But was Sunday’s flood a worrying warning of what was to come? Climate forecasts Climate Central reports that things can get much, much worse. Should we not cut greenhouse gas emissions and slow down global warming, far more of London could be regularly underwater by 2030.

Greenhouse gas emissions heat the earth’s atmosphere, melt the ice caps and raise sea levels. But a warmer atmosphere also makes adverse weather events – such as lightning floods – more likely.

Climate Central’s map shows the combined effect of both sea level rise and floods, by using red to show endangered areas. For millions of Londoners, it’s a pretty bleak picture.

By 2030, most of eastern Twickenham, Chiswick, Hammersmith and Fulham are covered in red – as well as Westfield White City and much of Kews Royal Botanic Gardens.

East London

With much of eastern London lying on low terrain, almost the entire area can be exposed to floods and sea level rise.

South London

Like the east, much of the land south of the river is low and flat. From Battersea to Deptford, Southwark to Peckham, there may not be much more than open water.

North London

Especially around the Lee River, the Hackney Marshes and Walthamstow reservoirs show the map red, creeping up the banks and lowering parts of Tottenham and the Lee Valley.

Climate Central’s interactive maps also let viewers change the variables, allowing for different levels of pollution, floods and even luck. Just of interest, in its absolute worst case scenario for 2100 (with ‘uncontrolled pollution’, ‘moderate’ flooding and ‘accidents’), the capital looks like this:
