This article examines the sixth of seven essential principles of the climate sciences--"We Change Earth's Climate." Written for the science teacher, the article covers greenhouse gases, land-use changes, and other human-induced causes of global climate change. Each issue of the free online magazine Beyond Weather and the Water Cycle is structured around one of the seven principles. The content provides background information, lessons, and activities for K-5 classrooms.

Student teams model the Earth's greenhouse effect using modeling clay, ice chunks, water, aluminum pie tins and plastic wrap. They observe and record what happens in this closed environment and discuss the implications of global warming theory for engineers, themselves and the Earth.

A terrific site to help younger students learn about global warming and the different ways that kids can help fight to prevent it.

This resource provides information on all of the aspects of global warming, climate change, and the future of the earth.

A detailed overview of the greenhouse effect, with explanations about Earth's atmosphere gases referred to as greenhouse gases, and the factors that influence the heat-trapping ability of a greenhouse. All information is reinforced through pictures, graphs, and learning activities. Learning activities give background, procedure, and assessment ideas.

Students observe demonstrations, and build and evaluate simple models to understand the greenhouse effect, the role of increased greenhouse gas concentration in global warming, and the implications of global warming theory for engineers, themselves and the Earth. In an associated literacy activity, students learn how a bill becomes law and research global warming legislation.

The Arctic plays an important role in regulating Earth's climate. The region reflects much of the Sun's energy and helps keep the planet cool. Data collected by NASA have revealed that sea ice in the Arctic has steadily declined over the past 30 years leading to increased solar radiation absorbed. Examine these images showing that the regions of greatest ice loss correspond with regions of greatest increase in absorption. Background information and teaching tips are provided.

Students learn about the advantages and disadvantages of the greenhouse effect. They construct their own miniature greenhouses and explore how their designs take advantage of heat transfer processes to create controlled environments. They record and graph measurements, comparing the greenhouse indoor and outdoor temperatures over time. Students are also introduced to global issues such as greenhouse gas emissions and their relationship to global warming.

Learn why scientists have been observing glaciers since before global warming came into the forefront. Learn about the different types of glaciers and the ways to monitor them. Some of the information may be dated. (April 14, 1999)

A two-part video which takes students on a climate adventure. Will the heroes find their way home? Will they save the plankton? [9:37]

An illustrated article highlighting the science behind carbon and fossil fuels. Diagrams and graphs help with understanding.

Information and activities looking at the impact of industrial and agricultural practices on global warming.

Read about Earth's oceans and the effects that climate have had on the rising temperatures over the past one hundred years. Discover how the Earth's ocean and atmosphere are interlocked so that when one changes, the other is affected.

Learn about polar ice, its effects on energy exchanges, how much surface area it covers, and how it is affected by global warming.

PBS offers a rare opportunity to explore the glaciers on France's Mt. Blanc in this engaging interactive site. Fun activities for students include following the process a snowflake takes to become a glacier.

PBS site provides links to understanding how glacier movement can reveal the effects of global warming. Contains links to view satellite images of glaciers from space, a video clip and slide show about a science expedition to a glacier in Greenland as well as an opportunity to ask an expert about glaciers and global warming.

This site, a companion to the original NOVA program on PBS, explores how Venetians are fighting the rising water levels that surround their historic city. Through interviews and video clips, the site takes an honest look at how global warming and destructive algae are destroying Venice, as well as delving into the proposed solutions to the problem. Requires Adobe Flash and Quicktime.

Dr. Tony Knap, of BIOS in Bermuda explains how climate change is causing ocean temperatures to rise, and what impacts it may bring around the world. [6:05]

Scientists predict the rise in sea level will only increase, and they're studying changes in the ocean and land to better understand how and why the water is rising. [6:20]

Is your state bird migrating farther north to escape the effects of global warming? This comprehensive resource answers this question by state.
