Can geoengineering plans save glaciers and slow sea level rise?

Scientists are exploring ambitious engineering projects to slow sea level rise by stabilizing vulnerable Antarctic glaciers. Proposals include pumping water from beneath glaciers to freeze them to the seabed and building underwater barriers to block warm currents. These controversial ideas aim to prevent catastrophic ice sheet collapse, which could raise sea levels by meters. While challenging and expensive, some researchers argue such interventions may become necessary to protect coastal areas, even with emissions reductions.
