The pictures, created by Nickolay Lamm and based on Climate Central’s sea level map data, show the possible consequences of 4°C warming and 2°C warming.
Scientists say that, on its current path, the world could see an increase in global warming by 4°C. The longstanding international target is a warming of 2°C.
The images below are projections based on a report compiled by Benjamin Strauss and Scott Kulp of Climate Central, an independent organisation of leading scientists and journalists covering changing climate.
The report states: "Carbon emissions causing 4°C of warming - what business-as-usual points toward today - could lock in 6.9 to 10.8 metres of global sea level rise, enough to submerge land currently home to 470 to 760 million people.

"Aggressive carbon cuts resulting in 2°C warming, the well-established international target, could bring the numbers as low as 3.0 metres and 130 million people."
The images show how these cities could look post-2100, based on our actions in this century.
More than 180 countries have pledged to cut or curb their emissions, but scientists say much bigger reductions are needed to limit man-made warming of the Earth to 2°C over pre-industrial times, the internationally agreed-upon goal.
The talks in Paris are due to run through until December 11.
The aim is to introduce a tougher and broader replacement to the 1997 Kyoto Protocol, which only required rich countries to cut their emissions.
