Why Geology Matters

Volcanic dust, climate change, tsunamis, earthquakesa &quote;geoscience explores phenomena that profoundly affect our lives. But more than that, as Doug Macdougall makes clear, the science also provides important clues to the future of the planet. In an entertaining and accessibly written narrative, Macdougall gives an overview of Earths astonishing history based on information extracted from rocks, ice cores, and other natural archives. He explores such questions as: What is the risk of an asteroid striking Earth? Why does the temperature of the ocean millions of years ago matter today? How are efforts to predict earthquakes progressing? Macdougall also explains the legacy of greenhouse gases from Earths past and shows how that legacy shapes our understanding of todays human-caused climate change. We find that geoscience in fact illuminates many of todays most pressing issuesa &quote;the availability of energy, access to fresh water, sustainable agriculture, maintaining biodiversitya &quote;and we discover how, by applying new technologies and ideas, we can use it to prepare for the future.
