Humanity is now, Kolbert explains, in the midst of the Anthropocene - a geologic era in which we are the dominant force shaping earth, sea, and sky. Under a White Sky covers slightly different ground. Kolbert, a New Yorker staff writer, has been covering the environment for decades: Her first book, Field Notes from a Catastrophe, traced the scientific evidence for global warming from Greenland to Alaska her second, The Sixth Extinction, followed the growing pace of animal extinctions. (The title refers to one of the consequences of engineering the Earth to better reflect sunlight: Our usual blue sky could turn a pale white.) These are some of the scenes from Elizabeth Kolbert’s new book, Under a White Sky, a global exploration of the ways that humanity is attempting to engineer, fix, or reroute the course of nature in a climate-changed world. And in Massachusetts, Harvard University scientists research injecting chemicals into the atmosphere to dim the sun’s light - and slow down the runaway pace of global warming. In Nevada, scientists nurse a tiny colony of one-inch long “Devil’s Hole pupfish” in an uncomfortably hot, Styrofoam-molded pool. In Australia, scientists collect buckets of coral sperm, mixing one species with another in an attempt to create a new “super coral” that can withstand rising temperatures and acidifying seas.
