Gizmodo: Geoengineering Could Be a Disaster for Astronomy

„That’s according to new models by Charlie Zender, an atmospheric physicist at the University of California, Irvine who presented the provacatively-titled research poster “Death of Darkness: Artificial Sky Brightness in the Anthropocene” at the the American Geophysical Union conference this month. In a nutshell, Zender found that injecting light-scattering particles into the stratosphere—one of the most widely-discussed strategies for rapidly cooling the planet—would have the unintended side-effect of messing with the incoming light from distant stars and planets.“
