What are assessments?

Assessments are essential tools for linking science and decision making. They survey, integrate, and synthesize science, within and between scientific disciplines and across sectors and regions.

Why do we need assessments?

Assessments support the critical analysis of issues, highlighting key knowledge that can improve policy choices and identifying significant gaps that can limit effective decision making. Assessment activities also track progress by identifying changes in the condition of the integrated Earth system over time, advances in the underlying science, and changes in human response.

What is the National Climate Assessment (NCA)?

Assessments have been integral components of USGCRP since its inception. Along with its strategic role as coordinator of Federal global change research, USGCRP is required by the Global Change Research Act of 1990 to conduct a National Climate Assessment (NCA). The NCA is an important resource for understanding and communicating climate change science and impacts in the United States. The Assessment:

  • Informs the nation about already observed changes, the current status of the climate, and anticipated trends for the future
  • Integrates scientific information from multiple sources and sectors to highlight key findings and significant gaps in our knowledge
  • Establishes consistent methods for evaluating climate impacts in the U.S. in the context of broader global change
  • Provides input to Federal science priorities and are used by U.S. citizens, communities, and businesses as they create more sustainable and environmentally sound plans for the nation’s future.

When will the next National Climate Assessment be completed?

The next National Climate Assessment is scheduled to be completed in early 2014. Information about the current assessment can be found on this site by following the links below and in the sidebar.

The National Climate Assessment and Development Advisory Committee (NCADAC) has overseen the development of the draft Third National Climate Assessment report, engaging over 240 authors in its creation. Access the draft report here.
