Previous predictions for rising sea levels might be incorrect, according to a new study.
The study - published in Proceedings of the National Academy of Sciences - found sea levels may rise by 2 metres by 2100.
These findings contradict the original prediction by the Intergovernmental Panel on Climate Change's Fifth Assessment Report in 2013, which suggested there will be a rise of just under a metre by the year 2100.
"For 2100, the ice sheet contribution is very likely in the range of 7-178cm but once you add in the glaciers and ice caps outside the ice sheets and thermal expansion of the seas, you tip well over two metres," lead author Professor Jonathan Bamber told the BBC.

Researchers found these increased levels could result in the loss of 1.79 million squared km of land, and amass to 187 million people displaced.
To put those figures into perspective, the land mass is larger than Libya, which covers 1.76m squared km, and those displaced would be equivalent to entire populations of New Zealand, Australia, Canada, the United Kingdom and Kenya.
Authors of the study explained a sea level rise of this magnitude "would clearly have profound consequences for humanity".
Using a structured expert judgement (SEJ) model, 22 scientists from the US and UK collated their expert knowledge to estimate various uncertainties surrounding sea level rise.
They measured accumulation, surface run off and discharge from the Greenland, West Antarctic and East Antarctic ice sheets to estimate the new figures.
Researchers estimated, if temperatures were to increase only by 2 degrees Celsius, there would be a 26cm sea level rise by 2100 and a maximum of 81cm. However, if temperatures were to rise by 5C and emissions were to go unchecked, could rise by 51cm with a maximum of 178cm.
"We find it plausible that SLR [sea level rise] could exceed 2m by 2100 for our high-temperature scenario," the authors wrote.
Looking further into the future, they also predicted the maximum rise in 2200 with a 5C temperature increase could be 7.5m due to the "instabilities coming into play in both West and East Antarctica".
The study's authors explained that since the 2013 predictions were released, "opinion has shifted toward a stronger ice sheet response and a larger credible range, for a given temperature change, than was considered plausible by the experts 6 years ago".
