"The Dark Cloud is the searing exposé of the immense toll the "cloud" takes on our environment. A simple "like" sent from our smartphones mobilizes a cascade of invisible consequences. This small notification, crossing the seven operating layers of the internet, travels around the world, using submarine cables, telephone antennas, and data centers, going as far as the Arctic Circle in what will soon constitute the largest infrastructure built by man. It turns out that the digital world, essential for communicating, working, and consuming, is much more tangible than we would like to believe. Today, it absorbs 10 percent of the world's electricity and represents nearly 4 percent of the planet's carbon dioxide emissions. We are struggling to understand these impacts, as they are obscured to us in the mirage of "the cloud.""--Publisher marketing.
