A Controversial Plan To Refreeze the Arctic is Seeing Promising Results

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. The group from the UK start-up Real Ice is in Cambridge Bay, a tiny coastal village in Nunavut, to try to prove they can grow and restore Arctic sea ice.

Their ultimate plan is to thicken ice over more than 386,000 square miles of the Arctic -- an area more than twice the size of California -- with the aim of slowing down or even reversing summer ice loss and, in doing so, help to tackle the human-caused climate crisis. 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.

Some Arctic scientists and experts have criticized Real Ice's methods as unproven at scale, ecologically risky and a distraction from tackling the root cause of climate change: fossil fuels. But the company says its project is inspired by natural processes and offers a last chance to protect a disappearing ecosystem as the world fails to act swiftly on climate change.
