Over more than a century, the global average temperature warmed 1.5F (0.8C). Learn the science of why this has happened, and what the future holds.

Solar energy is an appealing alternative to conventional sources of energy because it produces no greenhouse gases. An overview of its advantages and disadvantages is presented here.

Students explore heat transfer and energy efficiency using the context of energy efficient houses. They gain a solid understanding of the three types of heat transfer: radiation, convection and conduction, which are explained in detail...

Discusses the serious impact greenhouse gases are having on the pH balance of the oceans. It looks at the sea butterfly, which has more difficulty forming a shell as ocean acidification increases, as well as the damage acidification does...

There is evidence that the Earth's early atmosphere contained less oxygen but more carbon dioxide and water vapor than it does today. Increased emissions of greenhouse gases have led to climate change. Link to a test is included.

The atmosphere has not always been the same. It has been much the same, but nevertheless now contains more nitrogen and oxygen, and less carbon dioxide, than it did when the earth first formed. Recently, the addition of greenhouse gases...

Geothermal energy can be used as an efficient heat source in small end-use applications such as greenhouses, but the consumers have to be located close to the source of heat. Geothermal energy - heat from the earth (in most cases mineral...

A resource that looks at the causes and effects of climate change on the world-at-large. Find out how climate change affects animals like birds and the polar bear. The site also offers strategies for how we can reduce global warming...

This site from the Pennsylvania State University is maintained to provide teachers and students with examples of the bad science often taught in schools, universities, and offered in popular articles and textbooks.

How many times does lightning strike the Empire State Building? What state is know as the lightning capital of the U.S.? What time of day do tornadoes usually occur? Find out the answers to these questions and more on this enlightening...

A great article that looks at the US decision not to enter into the Kyoto Treaty from a European/World perspective. Article gives both the US and European/World sides of the issue.

An extensive research report on climate change in the Arctic and the impact this is having on the environment, flora and fauna, and indigenous peoples. (Updated: December 20, 2010)

This lesson plan encourages students to look at alternative methods of fuel and explore the various impacts each has on the environment.

Deforestation is clearing Earth's forests on a massive scale. In this lesson, students learn the value of large-scale forest landscapes and their role in the carbon cycle.

An explanation of how temperature is affected by the composition of the atmosphere and how energy flows in and out of Earth's atmosphere.

Travel through time and explore how the changing climate has affected sea ice, sea level, carbon dioxide levels, and global temperatures. Also, decide whether or not you would be affected if the sea level rose due to warmer temperatures...

Build your own windmill and see how the wind can be converted into energy to produce electricity. This science fair project should help you understand the use of wind as a source of alternative energy. The Science Buddies project ideas...

Video talks about the carbon cycle and uses a computer as a metaphor to show how the cycle can be disrupted by climate change. [3:55] Includes a short quiz and a list of additional resources to explore.

What kind of evidence could demonstrate that humans have begun to dominate and alter the life systems of Earth and have entered a new geological epoch? This article discusses the suggestion that we have entered the Anthropocene and...

An earth science collection where students can explore earthquakes, volcanoes, and more natural phenomena. The collection uses videos and interactive activities to investigate our dynamic planet and earth systems.

A discussion of the interactions between the four spheres of Earth and how they affect weather and climate. The slideshow is divided into two parts. The first deals with interactions between the atmosphere and the hydrosphere and the...

In this module, we will explore the concept of pollution and discuss how human use of resources relates. We will discuss the evidence for and against human-caused climate change. Students will compare and contrast pollution cleanup with...

Calculate the increased cost of heating homes and fueling cars since the energy crisis. Investigate alternative renewable and nonrenewable energy sources that can be used to decrease Americans' dependency on fossil fuels.

This comprehensive study guide covers the main terms and concepts needed for an earth science unit on the composition of the atmosphere. Review questions are included at the bottom of the study guide.
