A map has been released revealing that large areas of south east London could regularly be underwater by 2030.

The worrying flood map, created using new NASA water level projections, shows Lewisham, Greenwich and Bexley could be hit hard by rising sea levels, whilst Dartford could nearly disappear.

With extreme weather and flash floods becoming more and more common, the flood risk map has predicted almost the entire River Thames bank could be at risk.

This comes after south London was hit by a string of thunderstorms, heavy rain and flash flooding for the third time this summer last week.

The map was created using a new NASA tool to give snapshots of rising sea levels in the coming decades.

NASA’s sea level projection tool was released using data from the Intergovernmental Panel on Climate Change (IPCC).

Users can pull up the tool’s layers of maps, click anywhere on the global ocean and coastlines, and pick any decade between 2020 and 2150.

Areas lower than the selected water level and with an unobstructed path to the ocean are shaded red.

According to the map, anywhere near the River Thames could be regularly hit by heavy flooding by 2030.

In south east London, Lewisham could see areas of Deptford and Rotherhithe regularly flooded and under water, with the warning zone stretching inwards until Lewisham Station.

Greenwich will also continue to be victim to heavy flooded, with the entire Greenwich Peninsula marked in red by the NASA climate map.

Woolwich, Thamesmead and even Abbey Wood are also at risk of being below the annual flood level by 2030, as are areas of Slade Green, the centre of Erith and nearly the entirety of Dartford.

North of the River Thames doesn't fair any better.

The technology was based on the projections in the IPCC’s Sixth Assessment Report, released on August 9.

It also enables users to focus on the effects of different processes drive sea level rise such as the melting of ice sheets and glaciers.

This also includes the extent to which ocean waters shift their circulation patterns or expand as they warm which can affect the height of the ocean.

“As communities across the country prepare for the impacts of sea level rise, access to good, clear data is key to helping save lives and livelihoods,” said NASA Administrator Bill Nelson.
