Mad science or a radical revolution - could refreezing the Arctic actually work?

Plans to save ice in the polar regions and "repair" the climate using technology are a "flawed" distraction from the urgent need to reduce greenhouse gases, according to a new scientific assessment.

Re-freezing the North Pole? A giant sea curtain? High-tech efforts to save the Arctic are doomed, report finds

Moonshot proposals to save the planet’s ice sheets, including giant underwater sea curtains and refreezing Arctic ice, are gaining popularity as the planet heats up. But none of the most high-profile ideas are viable — worse, they may cause irreparable harm, according to a new study.

Polar geoengineering is dangerous and far too costly, say scientists

Underwater curtains and ice thickening divert attention from cutting fossil fuel use, warns climate research group.

Geoengineering is not going to save the poles from climate change

A review of the five main methods proposed for cooling down the poles or slowing the loss of ice concludes they are all wildly impractical, wouldn't work, or both.
