A wondrous story of scientific endeavor-probing the great ice sheets of Antarctica From the moment explorers set foot on the ice of Antarctica in the early nineteenth century, they desired to learn what lay beneath. David J. Drewry provides an insider's account of the ambitious and often hazardous radar mapping expeditions that he and fellow glaciologists undertook during the height of the Cold War, when concerns about global climate change were first emerging and scientists were finally able to peer into the Antarctic ice and take its measure. In this panoramic book, Drewry charts the history and breakthrough science of radio-echo sounding, a revolutionary technique that has enabled researchers to measure the thickness and properties of ice continuously from the air-transforming our understanding of the world's great ice sheets. To those involved in this epic fieldwork, it was evident that our planet is rapidly changing, and its future depends on the stability and behavior of these colossal ice masses. Drewry describes how bad weather, downed aircraft, and human frailty disrupt the most meticulously laid plans, and how success, built on remarkable international cooperation, can spawn institutional rivalries. The Land Beneath the Ice captures the excitement and innovative spirit of a pioneering era in Antarctic geophysical exploration, recounting its perils and scientific challenges, and showing how its discoveries are helping us to tackle environmental challenges of global significance.

In May 2014, the mountaineer and scientist John All fell into a crevasse near Everest and took a series of videos as he struggled to climb out 70 feet of ice and snow with fifteen broken bones - including 6 cracked vertebrae, internal bleeding, a severely dislocated shoulder, and his face covered in blood. The videos of him went viral and appeared in newscasts all over the world: CNN, BBC, Australia, Brazil, Israel, South Korea, Saudi Arabia, etc. and every website imaginable - from People Magazine to National Geographic. NPR called him "a badass for science." Yet this story is only the latest of All's adventures. He's also won a footrace for his life with a wild hyena, stepped on a black mamba in the African bush, and scaled Everest - all in pursuit of his true passion: the future of adaptation to our world's changing climate. Icefall is more than a fascinating adventure story-it is a report from the extremes, which hold new lessons about the impact of climate change. It is about the collapsing Andean glaciers, the hidden jungles in Honduras where native people have learned about surviving hurricanes, and the highest points on earth, where more scientific secrets lie. The result is a thrilling adventure memoir with profound lessons for how humans will adjust as our world continues to change beneath our feet.
