cold water poured on artificial clouds!

A controversial proposal to create artificial white clouds over the ocean in order to reflect sunlight and counter global warming could make matters worse, scientists have warned.

The proposed scheme to create whiter clouds over the oceans by injecting salt spray into the air from a flotilla of sailing ships is one of the more serious proposals of researchers investigating the possibility of “geoengineering” the climate in order to combat global warming.

However, a study into the effects of creating man-made clouds which reflect sunlight and heat back into space has found that the strategy could end up having the opposite effect by interfering with the natural processes that lead to the formation of reflective white clouds over the ocean.

Our research suggests that attempts to generate brighter clouds via sea spray geoengineering would at best have only a tiny effect and could actually cause some clouds to become less bright, said Professor Ken Carslaw of the University of Leeds.
