Some of the most extreme ideas for climate engineering involve reducing the sunlight falling on the Earth's surface, as a way to offset the increase in temperatures caused by greenhouse gas emissions. Caldeira calculates that reflecting just 2% of the Sun's light from the right places on Earth (mainly the Arctic) would be enough to counteract the warming effect from a doubling of carbon dioxide in the atmosphere.

In a separate study, Stephen Salter of the University of Edinburgh proposes building 300-tonne ships that could spray micrometre-sized drops of seawater into the air under stratocumulus clouds. "The method is not intended to make new clouds. It will just make existing clouds whiter," he wrote. The ships would drag turbines in their wake, which would provide the power needed to spray the water.
