whiter clouds

Researchers at the University of Edinburgh have published a proposal to whiten clouds by using remote-controlled sailing ships to spray a mist of seawater high into the air.

Whiter clouds would reflect more heat away from the Earth.

But vast new fleets of ships would be required to carry out the task on a big enough scale, and it would be vulnerable to local changes in weather.
