This Environmental Protection Agency (EPA) site focuses on the science and impacts of global warming or climate change, and on actions that help address global warming. It features games, events, and links to other relevant sites for kids and educators, including activities on climate and weather and the greenhouse effect. Full description.

This page contains information and photographs related to climate change and its impact. The World View of Global Warming project is documenting this change through science photography from the Arctic to Antarctica, from glaciers to the oceans, across all climate zones. Full description.

This resource provides an overview of the concept of global warming, which is thought to be due to man-made emissions of greenhouse gases, which are largely a result of the burning of fossil fuels and deforestation. It explores the possibility that the impacts of global warming may include desertification and the destruction of other ecosystems, extreme weather conditions, and a danger to agriculture. ...

This science-based world map depicts the local and regional consequences of global climate change. It identifies direct manifestations of a warming trend (fingerprints), and events that are consistent with the projections for global climate change and are likely to become more frequent and widespread with continued warming (harbingers). These signs are linked to a full description of conditions in ... Full description.

This unit includes classroom activities to help students understand global warming and its possible effects on human beings. Lessons in the unit provide students with opportunities to study global climate changes, discuss and debate the current arguments for and against global warming and the Greenhouse Effect, investigate the possibility of global warming and the Greenhouse Effect, and present their ...

These materials illustrate the principles of global warming and climate change due to natural and human-caused factors. They include a set of activities on the Earth's energy budget and future climate change. The energy budget model uses Mono Lake, California as an example. The future climate change activity uses the Special Report on Emissions Scenarios (SRES) from the Intergovernmental Panel on ... Full description.

These frequently asked questions include queries on global warming commonly addressed to climate scientists, and brief replies based on Intergovernmental Panel on Climate Change (IPCC) reports and other research in common, understandable language. This list will be periodically updated, as new scientific evidence comes to light. Links to additional information are embedded in the text. Full description.

This article describes an activity in which students use web-based resources to investigate global climate change. The investigation takes the form of a computer activity in which they collect data from the internet on temperature, concentrations of various gases, oxygen isotopes, and others. The activity begins by posing the question: 'Should the U.S. and other countries limit emissions of greenhouse ... Full description.

This site explains the global warming exhibit at the Marian Koshland Science Museum of the National Academy of Sciences and provides information and activities for students in regard to global warming. It includes an introduction to global warming and sections about the greenhouse effect and carbon cycle, as well as causes, impacts, responses and predictions of climate change. Each section has from ... Full description.

At this site students can explore scientific data on climate change relating to the atmosphere, the oceans, the areas covered by ice and snow, and the living organisms in all these domains. They will get a sense of how scientists study natural phenomena, how researchers gather evidence, test theories, and come to conclusions. Though climate change is not new, the study of how human activity affects ... Full description.
