Ancient Ice - What Glaciers Reveal About Climate Change

Glaciers have been around for a long time. Many formed at the end of the last ice age, about 20,000 years ago. Since then, they have shaped Earth-s landscape, helped cool the planet and provided living things with fresh water, all while weathering changes in Earth-s climate. Studying glaciers can tell us a lot about how Earth-s climate has shifted over time, how human activities are impacting the climate and what might occur in the future. Packed with information, vibrant photos and hands-on activities, this book helps students learn about glaciers, how they-re changing and what that might mean for the planet-s future.
