Greenhouse gas emissions and increased global temperature will change weather, climate, ecosystems, and food supply. Each degree Celsius (1.8 deg Fahrenheit) increase in global average temperature (up to 4 deg C) would likely result in the following: 5% to 10% less total rain in southwest North America, the Mediterranean, and southern Africa; 5% to 10% less streamflow in some river basins; 5% to 15% lower yields of some crops. The document clarifies short- and long-term consequences of various scenarios.
Assessing Economic Impacts of Greenhouse Gas Mitigation
May 15, 2009
Reliable estimates of the costs and benefits to the U.S. economy for various emissions reduction and adaptation strategies are critical to federal climate change R&D portfolio planning and investment decisions. At the request of the U.S. Department of Energy, the National Academies organized a workshop to consider these issues. The workshop participants discussed three dimensions: policy, analysis, and economics.
Strategies to Promote Commercialization and Deployment of Greenhouse Gas Intensity-Reducing Technologies and Practices
January 15, 2009
This report systematically examines the market readiness of key technologies important to meeting climate change mitigation goals. It assesses the barriers and business risks impeding their progress and greater market application. The report was sponsored by the U.S. Climate Change Technology Program (a multi-agency group led by the U.S. Department of Energy) and was submitted to the President and Congress in January 2009.
Scenarios of Greenhouse Gas Emissions and Atmospheric Concentrations
July 1, 2007
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.
Effects of Climate Change on Energy Production and Use in the United States
March 28, 2007
This report summarizes the effects of climate change on energy production and use in the United States. It also identifies where research could reduce uncertainties about vulnerabilities, possible effects, and strategies to reduce negative effects and increase adaptive capacity.
