As climate change is warming our planet, the ice in Earth's cryosphere is melting — from glaciers to mountaintop patches to permafrost. An unexpected result of this melting has been the discovery of artifacts that were long preserved in the ice's depths. Tools, clothing and, perhaps most remarkable, human bodies have been revealed at the edges the retreating ice. Examining these discoveries, along with traces of plants and animals also melting out of the ice, is the work of researchers in a brand-new scientific field called glacial archaeology. This one-of-a-kind introduction to the work of these researchers examines some of the fascinating artifacts that have been uncovered and the insights they provide into how our ancestors lived. It also describes the urgency of this work; as soon as these clues to the past become exposed to the elements, they begin to disintegrate.Award-winning author Claire Eamer keeps the interest level high with her intriguing stories, organized into thirteen chapters. The accessible text is complemented by loads of eye-catching visuals, such as photos of actual artifacts and mummified remains, along with Drew Shannon's full-color illustrations. The table of contents, timeline, references, glossary and index enhance the book's classroom utility. This timely book is an excellent choice for updated lessons on the impacts of changes in the environment. Information here covers subjects ranging from science and technology to environmental studies to history and geography.
