Their goal? To slow global warming.

As sea-ice vanishes, the dark ocean surface can absorb more of the Sun's energy, which accelerates warming. So the researchers want to thicken it to stop it melting away.

Welcome to the wackier side of geoengineering - deliberately intervening in the Earth's climate system to try to counteract the damage we have done to it.

Geoengineering includes more established efforts to lock up planet-warming gases, such as planting more trees and burying carbon underground.
