Examine a specific key question:
How vulnerable or resilient are the nation’s natural and human resources and systems to the changes in climate projected to occur over the decades ahead?

U.S. National Assessment of Climate Impacts
Doesn’t argue about whether climate change will occurAsks how significant climate change will be if climate model projections are correctUses two models with a range of sensitivityExamines forestry, agriculture, water, human health, and coastal regionsSets the stage for research, including information technology and observing systems

How large are the potential climate changes?
Temperature and Precipitation

What are the impacts for forestry, agriculture, water, human health and the coastal region?

The Nature of Environmental Problems
Many drivers of change are global – the impacts and decisions are “place-based”Every place is influenced by multiple stresses (climate, land use, pollution, etc)Cause and effect analyses are inadequate

National Assessment -Recommendations
Recommendation 1: Develop a More Integrated Approach to Examining Impacts and Vulnerabilities to Multiple Stresses
![Page 26: Environmental Sciences Jun 01](https://reader031.fdocuments.in/reader031/viewer/2022020311/577cc57f1a28aba7119c9508/html5/thumbnails/26.jpg)
What is Standing in Our Way?Integration of Observing Systems Common modeling framework that enables integrated, full system predictionFoundation for process studies that is geared toward predictionIntegrated Data and Information SystemVigorous connection to users/decision-makers

The Challenge is one of Scale not Capability
Mismatch of scales - problems are often regional or local while our efforts at developing a systems approach tend to be globalCurrently incapable of putting a global integrated picture together at a scale suitable to address many of the problems
![Page 28: Environmental Sciences Jun 01](https://reader031.fdocuments.in/reader031/viewer/2022020311/577cc57f1a28aba7119c9508/html5/thumbnails/28.jpg)
A More Realistic ApproachCreate an integrated approach at a tractable scale – a region or a state(s) defined by a set of problemsBuild toward a national and global framework based on advances at a regional scaleSuccess creates a data and model “pull”
