You pump that water out from under the glaciers. Melt drillholes like we already do there when we check out subglacial lakes, or to get through the ice shelves. Technology is well known, and pretty easy. Pump up the water from under the glaciers, and actually, the weight of the ice on it will cause that water to come up a well hole ninety percent of the way, just from pressure of all that weight. Then you pump it up the rest of the way, pipe it away from the glacier onto some stable ice nearby.”
