Hi All This may be an over simplification. It depends on what you spray where in the atmosphere and which bit of sky. Sea salt in the troposphere makes the tops of clouds over the sea, which were already white, a bit whiter but does not affect blue skies or clouds over land where most people live.
Changes to rainfall patterns following a rather simple spray plan are shown below from Stjern et al. 2018. [cid:[email protected]] With more complicated spraying in different seasons and regions we can tweak monsoons and the Indian Ocean dipole.

It's nice to be mentioned in today's New York Times review of "Under a White Sky" https://www.nytimes.com/2021/02/10/books/review-under-white-sky-elizabeth-kolbert.html The title of Kolbert’s book comes from one possible side-effect of “solar geoengineering” (or “solar radiation management,” in what’s supposed to be the less scary parlance). Spraying light-reflective particles into the atmosphere will make blue skies look white. One climate scientist keeps a running list of concerns about geoengineering. No. 1 is the worry that a disruption of rainfall patterns could cause drought in Africa and Asia. No. 28 is the philosophical quandary looming over it all: “Do humans have the right to do this?” -- Alan Alan Robock, Distinguished Professor Chair-Elect, AGU College of Fellows Associate Editor, Reviews of Geophysics Department of Environmental Sciences Phone: +1-848-932-5751 Rutgers University E-mail: [email protected]<mailto:[email protected]> 14 College Farm Road http://people.envsci.rutgers.edu/robock New Brunswick, NJ 08901-8551 ☮ https://twitter.com/AlanRobock "I've got a feeling 21 is going to be a good year" - The Who from the album Tommy [Signature] -- You received this message because you are subscribed to the Google Groups "geoengineering" group.
