NUIG research pours cold water on 'cloud brightening' method

The theory of 'Cloud brightening' was first first put forward in 1990, but recent research questions its effectiveness

Research published by pollution experts at NUI Galway has poured cold water on the effectiveness of so-called ’’cloud brightening’’ to tackle climate change.

Cloud brightening, a theory first put forward in 1990, suggests the manipulation of cloud cover by spraying water-based particles into clouds, thereby reflecting more sunlight back into space, and subsequently reducing radiation.
