Researchers from the Niels Bohr Institute are part of a team that has calculated the long-term outlook for rising sea-levels in relation to the emission of greenhouse gases and pollution of the atmosphere using climate models, reports ScienceDaily.
In the pessimistic scenario, emissions keep increasing, and the sea rises 1.1 metres by the year 2100 and 5.5 metres by 2500.
Even in the most optimistic scenario, which requires extremely dramatic climate-change goals, major technological advances and strong international co-operation to stop emitting greenhouse gases and polluting the atmosphere, the sea would rise 60cm by 2100 and 1.8 metres by 2500.
The two more realistic scenarios, based on stablising emissions and pollution, show a sea-level rise of about 75cm by the year 2100 and 2 metres by 2500.
