U.S. Global Change Research Program
(USGCRP)
Major Recommendations for the USGCRP*
1. Reorganize the program around integrated scientific-societal issues to facilitate
crosscutting research focused on understanding the interactions among the climate,
human, and environmental systems and on supporting societal responses to climate
change.
2. Establish a U.S. climate observing system, defined as including physical, biological,
and social observations, to ensure that data needed to address climate change are
collected or continued.
3. Develop the science base and infrastructure to support a new generation of coupled
Earth system models to improve attribution and prediction of high-impact regional
weather and climate, to initialize seasonal-to-decadal climate forecasting, and to provide
predictions of impacts affecting adaptive capacities and vulnerabilities of environmental
and human systems.
4. Strengthen research on adaptation, mitigation, and vulnerability.
5. Initiate a national assessment process with broad stakeholder participation to
determine the risks and costs of climate change impacts on the United States and to
evaluate options for responding.
6. Coordinate federal efforts to provide climate services (scientific information, tools,
and forecasts) routinely to decision makers.

Research to Meet the Challenges of Climate Change.

NASA Earth System Science
50 Years of Earth Observations from Space
The U.S. National Research Council (NRC) reviewed U.S. accomplishments
in Earth remote sensing from space and concluded (summarized):
• The daily synoptic view of Earth from space has revolutionized Earth
studies and helped society manage environment and resources
• Long time series are required and the value of data sets increases with
time
• Scientific advances result from science-technology synergy, and societal
benefit of measurements increases with increasing accuracy
• Have indisputable benefit of multiple synergistic observations (satellite
and non-satellite) linked with models
• To achieve full benefit of observations, need infrastructure (models,
computing, ground networks, personnel)
• Full and open access to global data capitalizes on investment
• Space observations have catalyzed interdisciplinary science and can be
expected to lead to remarkable discoveries in the future

20 Years of Earth System Science
• We have learned many things about the Earth system and our understanding:
•
•
•
We have documented and quantified variability, trends, and change in the Earth
system
High-quality observations reveal new phenomena and processes
We have learned in some cases that our understanding was inadequate – or wrong
• We have developed advanced capabilities to:
•
•
•
•
•
There are new phenomena and problems to be addressed, for example:
•
•
•
•
Handle and process large volumes of data
Create multi-sensor, multi-satellite data products and time series data products
Conduct inter- and multi-disciplinary science
Improve component models and advance toward Earth System models
The ice is melting faster than predicted
The ocean is becoming more acid, with potential large impacts on ecosystems
There are concerns about increases in the frequency and intensity of extreme events -especially with respect to their impacts in built-up areas with large human populations
Our successes in documenting change are leading to new demands for
scientific assistance in the development and implementation of policies to
address climate change

Decision support is becoming an increasing important element within the USGCRP
Observations are needed for monitoring and assessing efficacy of mitigation

Observations
The U.S. NRC’s Decadal Survey for ~2010-2020
• In 2007, the Space Studies Board of the National Research
Council (NRC) of the U.S. National Academies of Science,
Engineering, and Medicine released a community assessment
and strategy for the future entitled:
Earth Science and Applications from Space:
National Imperatives for the Next Decade and
Beyond (aka the “Decadal Survey”)
• The Decadal Survey, in combination with the NRC’s reports
on the USGCRP and other related activities, provides guidance
for NASA’s future Earth Science program
