An anonymous reader shares a report: Deep in the Canadian Arctic, scientists and entrepreneurs brave sub-zero temperatures, whipping winds and snowstorms to drill holes through the sea ice to pump out the seawater below and freeze it on the surface. It's a bold plan, and one of many controversial geo-engineering proposals to save the planet's vulnerable polar regions that range from installing a giant underwater "curtain" to protect ice sheets, to sprinkling tiny glass beads to reflect away sunlight.
