Regional Climate Change

Meeting the adaptation needs of decision makers

These figures illustrate a talk by Jonathan Overpeck presented December 15 during session PA12A of the 2008 AGU Meeting in San Francisco, California.

Figure 1.


Changes in annual soil moisture (left) and maximum number of consecutive dry days (right) projected to occur by the late 21st century based on the average of many global climate models. Stippling denotes areas of greater model agreement. Together these projections indicate that much of the West, and particularly the Southwest, will likely become drier and more drought-prone as global climate change continues, a tendency that will be exacerbated by continued warming in the region.

Projected high-end possible sea-level rise (2m) by the end of the 21st century as it would affect the San Francisco region. Areas in red are those that would become flooded in the absence of engineered barriers. (Illustration courtesy University of Arizona.

Map showing the regional foci of the nine existing NOAA-funded Regional Integrated Sciences and Assessment (RISA) Programs. Each RISA program focuses on climate change adaptation, as well as helping decision-makers (“stakeholders”) in society deal more effectively with climate variability and change.
