Carbon Dioxide Information Analysis Center (CDIAC)
The CDIAC is the primary climate change data and information analysis center of the United States Department of Energy (DOE). Its data holdings include records of the concentration of carbon dioxide and other radiatively active gases in the atmosphere, emissions of carbon dioxide, long term climate trends, and more.
Climate Change: Discovery of Global Warming
Created by science historian Spencer Weart, this site provides a thorough history of climate change along with access to basic facts and detailed current technical information. This site supplements Weart’s book The Discovery of Global Warming which is available as an Alverno e-book.
Earth System Research Laboratory - Global Monitoring Division
A division of the National Oceanic and Atmospheric Administration (NOAA), the Global Monitoring Division (GMD) maintains accurate, long-term records of atmospheric gases, aerosol particles, and solar radiation. The GMD’s mission is to understand the Earth's atmospheric system in order to develop products that will advance global and regional environmental information and services.
Global Climate Change: Vital Signs of the Planet
Published by NASA, this site provides resources related to the measurement, analysis, and dangers of global climate change. It features visual representations and interactive tools including a Climate Time Machine that allows users to go backward and forward through time to visualize key climate indicators, including Sea Ice, Sea Level, Carbon Dioxide, and Global Temperature.
U. S. Global Change Research Program
The U. S. Global Change Research Program (USGCRP) supports research on the interactions of natural and human-induced changes in the global environment and their implications for society. The reports provided on this site will help students understand, assess, and predict global change.
Intergovernmental Panel on Climate Change (IPCC)
The role of the IPCC is to assess technical and socio-economic information relevant to understanding the scientific basis of risk of human induced climate change, its potential impacts, and options for adaptation and mitigation. Its site provides free access to numerous publications and reports which are available in several languages.
National Oceanic & Atmospheric Administration - Climate
The NOAA site provides access to wealth of information on the climate and global warming. It includes archived weather data dating back to 1900, weekly U. S. drought assessments, publication and reports on global climate change, and much more.
Center for Climate and Energy Solutions
The Center for Climate and Energy Solutions is nonpartisan, nonprofit organization that seeks to provide independent research into global climate change. Its site includes access to publications and reports that provide basic, as well as in-depth perspectives on the issues associated with global warming and government policy.
