Brighter clouds can increase reflectivity

Brighter clouds may help keep our planet cooler.

Atmospheric Sciences’ Tom Ackerman and Rob Wood recently contributed to a proposal that would test the effectiveness of spraying sea-salt particles into marine clouds in order to make them brighter. According to The Economist, cloud physicist John Latham hypothesized that brighter clouds could cool the Earth enough to compensate for increased warming caused by greenhouse gas emissions in 1990. Several decades later and with the help of the two UW scientists, field tests on the subject could come to fruition. Ackerman, Wood, and other researchers want to test whether this process would really increase the number of water droplets clouds hold and, as a result, the amount of sunlight they reflect into space.
