What If We Lost the Sky? - NYTimes.com - 0 views

  • What is the sky worth? This sounds like a philosophical question, but it might become a more concrete one. A report released last week by the National Research Council called for research into reversing climate change through a process called albedo modification: reflecting sunlight away from earth by, for instance, spraying aerosols into the atmosphere. Such a process could, some say, change the appearance of the sky — and that in turn could affect everything from our physical health to the way we see ourselves. If albedo modification were actually implemented, Alan Robock, a professor of environmental sciences at Rutgers, told Joel Achenbach at The Washington Post: “You’d get whiter skies. People wouldn’t have blue skies anymore.” And, he added, “astronomers wouldn’t be happy, because you’d have a cloud up there permanently. It’d be hard to see the Milky Way anymore.”
  • Losing the night sky would have big consequences, said Dacher Keltner, a psychology professor at the University of California, Berkeley. His recent work looks at the health effects of the emotion of awe. In a study published in January in the journal Emotion, he and his team found that people who experienced a great deal of awe had lower levels of a marker of inflammation that has been linked to physical and mental ailments. One major source of awe is the natural world. “When you go outside, and you walk in a beautiful setting, and you just feel not only uplifted but you just feel stronger,” said Dr. Keltner, “there’s clearly a neurophysiological basis for that.” And, he added, 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.”
