New Report: Responding to the Challenge of Climate and Environmental Change
NASA's Plan for a Climate-Centric Architecture for Earth Observations and Applications from Space

Earth is a complex, dynamic system we do not yet fully understand. The Earth system, like the human body, comprises diverse components that interact in complex ways. We need to understand the Earth's atmosphere, lithosphere, hydrosphere, cryosphere, and biosphere as a single connected system. Our planet is changing on all spatial and temporal scales. The purpose of NASA's Earth science program is to develop a scientific understanding of Earth's system and its response to natural or human-induced changes, and to improve prediction of climate, weather, and natural hazards.

NASA recently completed deployment of the Earth Observing System, the world's most advanced and comprehensive capability to measure global climate change. Over the coming decade, NASA and the Agency's research partners will be analyzing EOS data to characterize, understand, and predict variability and trends in Earth's system for both research and applications. Earth is the only planet we know to be capable of sustaining life. It is our lifeboat in the vast expanse of space. Over the past 50 years, world population has doubled, grain yields have tripled and economic output has grown sevenfold. Earth science research can ascertain whether and how the Earth can sustain this growth in the future. Also, over a third of the US economy - $3 trillion annually - is influenced by climate, weather, space weather, and natural hazards, providing economic incentive to study the Earth.

NASA Earth System Science conducts and sponsors research, collects new observations from space, develops technologies and extends science and technology education to learners of all ages. We work closely with our global partners in government, industry, and the public to enhance economic security, and environmental stewardship, benefiting society in many tangible ways. We conduct and sponsor research to answer fundamental science questions about the changes we see in climate, weather, and natural hazards, and deliver sound science that helps decision-makers make informed decisions. We inspire the next generation of explorers by providing opportunities for learners of all ages to investigate the Earth system using unique NASA resources, and our Earth System research is strengthening science, technology, engineering and mathematics education nationwide. This is a fundamental part of our mission because the leaders and citizens who will meet challenges of tomorrow are the students of today.
