7 meters of sea-level rise – what you would get if the whole Greenland Ice Sheet melted. But the tricky question is: how much of this ice will be melted in the next decades, and how fast will it occur? This piece of information is critical in order to plan for present and future populations living in coastline areas, all around the world. How much and how fast can the Greenland Ice Sheet melt ? In ...[Read More]

Image of the Week – Delaying the flood with glacial geoengineering

February 1, 2019

As the climate is currently warming, many countries and cities are preparing to cope with one of its major impacts, namely sea-level rise. Up to now, the mitigation of climate change has mainly focused on the reduction of greenhouse gas emissions. Large-scale geoengineering has also been proposed to remove carbon from the atmosphere or inject aerosols into the stratosphere to limit the rise in tem ...[Read More]
