As research into engineering techniques that might one day be employed to artificially cool the planet advances, some scientists are calling for adoption of an oversight framework to guide what to study... and when to stop.
Marine cloud brightening, a geoengineering approach to cooling the surface of the Earth by increasing the reflectivity of marine clouds, may be more difficult to execute than anticipated, according to a new NOAA study.
New research indicates that man-made clouds formed along shipping routes dissipate too quickly to provide insight into the cooling effect of naturally occuring marine clouds.
