The need to understand the planet we call home has never been greater. As the population of our pale blue dot continues to grow, humans and all living things vie for an ever-shrinking pool of natural resources. Fresh water. Clean air. Food. Habitable land. As Earth's climate changes in response to human and natural causes, these resources are strained.

NASA's contingent of dedicated Earth scientists and engineers -- the world's largest -- together with its armada of Earth satellites and airborne instruments, study all aspects of the Earth system--its ocean, atmosphere, ice, land and biosphere. Together, this conflux of humans and machines is advancing our scientific understanding of our ever-changing Earth system, helping to meet the needs of society.

JPL studies help us identify how Earth's climate is changing, understand the causes of these changes, and support development of models used to predict future global change. Currently, JPL has six dedicated Earth science spacecraft in orbit, with another five instruments flying aboard NASA's Terra, Aqua and Aura spacecraft. Several more missions are planned for launch in the next few years. Decision makers around the world use JPL Earth science data to support policy-making and resource management decisions.

Eyes on the Earth

Global climate change website/Eyes on the Earth 3-D
Visit NASA's award-winning and Webby-nominated Global Climate Change website, devoted to educating the public about Earth's changing climate. The site provides easy-to-understand information about the causes and effects of climate change and how NASA studies it. New content is added daily. A highlight is "Eyes on the Earth 3-D," an interactive program that allows the public to "fly along" with JPL's fleet of Earth science missions and others from NASA and even see near-real-time satellite data.
