Scientists believe that global sea levels could rise far more than predicted, due to accelerating melting in Greenland and Antarctica. The long-held view has been that the world's seas would rise by a maximum of just under a metre by 2100. This new study, based on expert opinions, projects that the real level may be around double that figure. The question of sea-level rise was one of the most controversial issues raised by the Intergovernmental Panel on Climate Change (IPCC), when it published its fifth assessment report in 2013. Ice scientists are also concerned that the models currently used to predict the influence of huge ice sheets on sea levels don't capture all of the uncertainties about how these are now melting.
