SIDELIGHTS: Richard B. Alley is a professor of geo-sciences at Pennsylvania State University, where he specializes in glaciology, the study of ice sheet stability, and the investigation of ancient climatology as represented in ice cores. Alley is a scientist whose “contributions to the ice core, sea-level, and climate communities have been exceptional,” stated Samuel C. Colbeck of the Earth and Environmental Systems Institute in the citation for Alley’s 1996 Horton Award.
In The Two-Mile Time Machine: Ice Cores, Abrupt Climate Change, and Our Future, Alley presents detailed research findings derived from the study of two-mile-long ice cores drilled and extracted from the ice covering Greenland. These cylindrical cores offered Alley and other scientists access to more than 110, 000 years of uninterrupted climatic information, sealed within the ice. Alley also describes the Greenland expeditions themselves, offers a primer on the use of ice cores to examine climate history, and details the methodologies used to collect and analyze the ice cores.
Some of Alley’s findings were unexpected, even alarming, especially in terms of current controversies surrounding global warming and abrupt climate change. He discovered, for example, that the last ice age ended not in a gradual decline over decades or centuries, but sharply and quickly within a three-year period. He notes that throughout the history represented in the ice cores, global climate has been much colder than the relatively mild temperatures experienced during the time period during which modern humans developed. The relatively warm and stable climate of the last 10, 000 years, Alley contends, is not the norm. He identifies factors that contribute to climate change, including continental drift, wind patterns, the concentration of greenhouse gases in the atmosphere, and changes in warmth and patterns of the ocean currents. Alley concludes that global climate has, does, and likely will again change abruptly and with little warning. Though not alarmist in his predictions, Alley suggests that climatic disaster is inevitable, whether precipitated by man-made influences or by natural factors that have been in play for millennia. Ultimately, he concludes that “proceeding as if humanity could affect climate change is only prudent,” noted Ray Olson in Booklist.A Publishers Weekly reviewer called Alley’s book a “brilliant combination of scientific thriller, memoir and environmental science” that “provides instructive glimpses into our climatic past and global future.” Olson concluded by calling the study “wonderfully accessible, information-packed science reading.”
