"Relatively low cost" plan would cool the Earth's poles by 2 °C,New research suggests that cooling the poles by 2 °C, and re-freezing the Arctic and Antarctic, is "feasible at relatively low cost with conventional technologies," if humanity agrees that a rising sea level is worse than this plan's side effects.

New research suggests that cooling the poles by 2 °C, and re-freezing the Arctic and Antarctic, is "feasible at relatively low cost with conventional technologies," if humanity agrees that a rising sea level is worse than this plan's side effects.
