Beginning with Sally Ride’s unique, astronaut’s-eye view of Earth’s fragile atmosphere, Mission: Planet Earth describes how water, air, and other climate systems shape our world, and how a disruption in one part of the system can spread through the entire planet. Drawing on the latest scientific research and presenting a clear, even-handed account of the current state of climate studies, illustrated with helpful diagrams and stunning photographs of and from the front lines of climate change, here is a celebration of Earth’s natural complexity–and a call to action for a new generation.
