Alan Robock. "Has the time come for geoengineering?" The Bulletin. August 14th, 2008: "7. Whitening of the sky (but nice sunsets). Atmospheric aerosols close to the size of the wavelength of light produce a white, cloudy appearance to the sky. They also contribute to colorful sunsets, similar to those that occur after volcanic eruptions. The red and yellow sky in The Scream by Edvard Munch was inspired by the brilliant sunsets he witnessed over Oslo in 1883, following the eruption of Krakatau in Indonesia.13 Both the disappearance of blue skies and the appearance of red sunsets could have strong psychological impacts on humanity."
