According to Dacher Keltner, a psychology professor at the University of California, losing the night sky would have big consequences. “When you go outside, and you walk in a beautiful setting, and you just feel not only uplifted but you just feel stronger. There’s clearly a neurophysiological basis for that," says Keltner adding that looking up at a starry sky provides “almost a prototypical awe experience,” an opportunity to feel “that you are small and modest and part of something vast.” If we lose the night sky “we lose something precious and sacred.” “We’re finding in our lab that the experience of awe gets you to feel connected to something larger than yourself, see the humanity in other people,” says Paul K. Piff. “In many ways it’s kind of an antidote to narcissism.” And the sky is one of the few sources of that experience that’s available to almost everybody: “Not everyone has access to the ocean or giant trees, or the Grand Canyon, but we certainly all live beneath the night sky.”
Alan Robock says one possible upside of adding aerosols could be beautiful red and yellow sunsets as “the yellow and red colors reflect off the bottom of this cloud.” Robock recommends more research into albedo modification: “If people ever are tempted to do this, I want them to have a lot of information about what the potential benefits and risks would be so they can make an informed decision. Dr. Abdalati says that deploying something like albedo modification is a last-ditch effort adding that “we’ve gotten ourselves into a climate mess. The fact that we’re even talking about these kinds of things is indicative of that.”"
