Brent Minchew has a plan that could stop the “Doomsday Glacier” in its tracks, and we don’t even need new technology to do it. The Caltech glaciologist returns to unveil an intervention that could save coasts around the world: refreezing Thwaites Glacier to its own bedrock using passive principles of physics. Brent walks Hakeem through the natural process that slows glaciers down, and lays out a plan to investigate if they can truly deploy it on the world's most precarious glacier.
