![What saved the West Antarctic Ice Sheet 10,000 years ago will not save it today
The retreat of the West Antarctic ice masses after the last Ice Age was reversed surprisingly about 10,000 years ago. This is in stark contrast to previous assumptions. In fact, it was the shrinking itself that stopped the shrinking: relieved from the weight of the ice, the Earth crust lifted and triggered the re-advance of the ice sheet. However, this mechanism is much too slow to prevent dangerous sea-level rise caused by West Antarctica’s ice-loss in the present and near future. Only rapid greenhouse-gas emission reductions can.

![Rapid emissions reductions would keep CO2 removal and costs in check
Jessica Strefler from the Potsdam Institute for Climate Impact Research on her new paper.
Rapid greenhouse-gas emissions reductions are needed if governments want to keep in check both the costs of the transition towards climate stabilization and the amount of removing already emitted CO2 from the atmosphere. To this end, emissions in 2030 would need to be at least 20 percent below what countries have pledged under the Paris climate agreement, a new study finds – an insight that is directly relevant for the global stock-take scheduled for the UN climate summit in Poland later this year. Removing CO2 from the atmosphere through technical methods including carbon capture and underground storage (CCS) or increased use of plants to suck up CO2 comes with a number of risks and uncertainties, and hence the interest of limiting them.
