That's what David Young, a member of the panel that created the report, says. The fully automated vessels will cross the oceans absorbing water and spraying it into the skies. They say this will help the formation of big, whiter clouds, which will make the sun light bounce, lowering temperatures.
The idea seems neat, but the concept of anyone in planet Earth claiming to understand how climate works to this extend blows my mind. We are still trying to grasp how a complex system like the weather works, but someone wants to put an idea like this in motion, without knowing about the ultimate consequences? Like we say in my home country: Do you experiments with pop soda.
