Nature Aggressive efforts to limit global warming will sharply reduce future sea-level rise,  suggests a paper published in Nature.  Icebergs in Sermilik Fjord, SE Greenland Credit: Donald Slater A second paper, also published in Nature, indicates that warming of 3 °C could cause sea level to increase by 0.5 cm every year by 2100 as a result of melting Antarctic land ice. The findings provide further insight into the impact of melting land ice on global sea-level rises. This animation shows the rate at which the ice thickness is changing in meters per year (more red/yellow means faster thinning and thus faster ice loss) as the Antarctic Ice Sheet responds to changes in the atmosphere and ocean due to one potential climate scenario. This simulation, using the BISICLES ice sheet model, represents one of hundreds of such simulations used for this work to characterize ice sheet response to changes in the climate.
