Rising sea levels pose a significant threat to coastal communities and low-lying countries worldwide. As polar ice melts at an accelerating rate, scientists are exploring technological interventions known as “polar geoengineering” to mitigate the impacts. These interventions include underwater curtains to protect outlet glaciers and boreholes to drain water from ice sheets. However, the proposals have sparked controversy, with critics arguing that they detract from decarbonization efforts and raise concerns about environmental impacts. The political and regulatory hurdles to implementing these projects are also significant, with international agreements and collaboration required.
