What is Geoengineering?
It’s human manipulation of the climate. Scientist believe it could be a way of slowing down global warming while efforts to reduce greenhouse gas emissions continue. Cloud whitening is one example. Geo engineers are proposing to use off-shore vessels to pump sea spray into the atmosphere. The salt particles in the spray would in theory help to form brighter clouds that reflect more sunlight back into space, thus having a cooling effect on climate. Unfortunately scientists from the University of Leeds and the Finnish Meteorological Institute found that generate brighter clouds may actually hinder natural cloud formation in some areas.
