National Global Change Programs:

How will we know if climate change mitigation or adaptation policies and practices we choose to take are effective? What communities or ecosystems are most vulnerable to negative change and thus need attention sooner rather than later? How close are ecosystems and resources to thresholds of major change? What actions can we take and will those actions be effective? To answer these questions, USGS scientists have had to change the way we study and observe the environment, by linking our biologic, geologic, hydrologic, and geographical observing networks to form an early warning system for change in the function of whole ecosystems, watersheds, regions, and continents. more

Multidimensional Approaches to Addressing Global Climate Change

Climate Effects Network
Research and Development Program (R&D):
Science Applications and Decision Support (SADS):

To answer the complex questions climate change raises requires the integrated analysis of multiple science disciplines across local, regional, and global scales. The Climate Effects Network has established the framework necessary to develop and make widely accessible integrated information on the status and trends of ecosystems and natural resources in a changing climate and an adapting society.more

The earth's surface does not exist in a static, unchanging "natural" condition interrupted only by the work of humans, but instead it is a dynamic system of which humans are a part. Knowledge about changes to the Earth's surface and the underlying processes that induce them has enormous impact on how society responds to these changes and, ultimately, the cost of responding to change.more

The USGS integrates climate- and environmental-change datasets with conceptual and digital models across disciplines including remote sensing, geography, geology, biology, and hydrology to better understand impacts to natural resources, agriculture, and human populations on decadal and regional time scales, local to global spatial scales, and weather to climate process scales. more
