Large parts of London could be below the annual flood level by 2030, according to new predictions.
A study by Climate Central claims tens of millions more people are claimed to be at risk of flooding if we don’t start cutting our use of fossil fuels and emitting green house gases.
The latest scientific data has shown the scale of the issues London could face.
Detailed maps have been produced so you can see how your street could be affected (but remember, it is just a prediction).
The organisation warns users that the map does not account for factors including the frequency of storms, erosion, or how rivers contribute to rising sea levels.
It also warns that estimates do not factor in man-made structures to prevent further damage - meaning it is likely some areas will not face the true expected scale of damage.
We've looked at what the predictions are for London by 2030.
East London
Parts of East London look set to escape the predictions of widespread flooding as a result of rising sea levels.
But the boroughs of Barking and Dagenham, Newham and Redbridge are at risk as those areas are highlighted in red, meaning they could be partially below the annual flood level by 2030.
North London
The map suggests that Tottenham Hale, which is known for its close proximity to the River Lea, could be left underwater in the next ten years.
Central London
In central, parts of Chelsea have been placed in the red zone, along with Southwark.
South London
Parts of Greenwich, Kingston and Wandsworth appear to be in the red zone.
West London
Areas in Hammersmith and Richmond are all in the red.
Why is this happening?
Pollution of greenhouse gases in the atmosphere cause the planet to wamr up and in turn, this melts ice sheets, glaciers which increases the volume of the world's oceans.
According to Climate Central, over the course of 21st century, global sea levels are projected to rise between 2 and 7 feet, possibly more.
They note key variables will be how much warming pollution humanity dumps into the atmosphere and how quickly the land-based ice sheets in Greenland and especially Antrartica destabilise.
Activists are calling on the government to tackle climate change and to prepare for rising sea levels as a result of the melting ice caps.
Back in January last year, Dr Tom Cameron, senior lecturer in ecology, said: "There’s a lot of different reasons why this is happening.
"The main reason is that this projection is looking at the maximum tidal flux, global sea level rise which means more water in the sea.
"A lot of people talk about the ice that is all going to melt and we have strong evidence to suggest that’s the cause in the Arctic. The alps have glacial melting that will eventually go to the sea.
"Lots of reasons why we are losing water like climate warming, it all changes weather patterns.
"Combined with high tides and high pressure, the high sea levels mean there are more tides that burst the banks more often."
