Uses and Limitations of Observations, Data, Forecasts, and Other Projections in Decision Support for Selected Sectors and Regions

Scientific information about Earth's climate, water, air, land, and other dynamic processes is essential for our understanding of humankind's relationship to our natural resources and our environment. This report examines contributions of Earth science information in decision support activities and their relationship to climate change science.

Scenarios of Greenhouse Gas Emissions and Atmospheric Concentrations

The findings presented in this report draw from scenarios designed to stabilize the influence of a suite of greenhouse gases. Three climate-modeling groups independently developed a reference scenario and then developed four contrasting stabilization scenarios for comparison.
