Understanding Climate Change
In the past, Earth’s climate has had both warm and cool periods. Changes from one period to another were caused by natural events, such as Earth’s orbit changing or natural disaster like asteroid impacts and large volcanic eruptions. The last cool period ended about 11,500 years ago. Since then, Earth has been in a warm period, which has allowed humans civilizations to grow and thrive.
Effects of Climate Change Scientists studying climate change usually examine changes in average global temperatures. However, they must also examine changes in precipitation patterns and the frequency of severe weather, such as heatwaves or droughts. Some of these changes to Earth’s climate affect specific regions, like variation to El Niño in North and South America, while other changes affect the entire planet such as rising sea levels resulting from melting ice caps.
The Greenhouse Effect Keeps Earth Warm Earth is kept warm by a natural process called the greenhouse effect. This process traps energy from the sun in our atmosphere, which then acts like a giant greenhouse surrounding Earth. This “greenhouse” keeps Earth’s average surface temperature at a warm 59°F. Without the greenhouse effect, the temperature would drop to −0.4°F, or well below freezing.
The greenhouse effect works because of gases in the atmosphere. The most common greenhouse gases are carbon dioxide, methane, and water vapor. These gases trap heat from the sun in the atmosphere. Otherwise, this heat would escape into space.
Since around 1800, levels of greenhouse gases in the atmosphere have been rising. This increase is due mainly to people burning fossil fuels, such as coal, oil, and natural gas, that release carbon dioxide into the atmosphere. Many scientists believe that the increase in carbon dioxide and other greenhouse gases is causing Earth to warm. Scientists often refer to this as the enhanced greenhouse effect because the warming is happening at an increased rate because of human activity.

Study the diagram below.
Energy from the Sun
This diagram shows what happens to energy from the sun once it enters Earth’s atmosphere. Some energy is absorbed by Earth’s surface. Some is reflected back into space. Some is trapped in a layer of gases that surrounds Earth. This trapped heat may be causing global warming.

Fossil Fuels and Climate Change Portfolio
Use what you've learned from the article, the diagram and the two videos to write a short essay (1-3 paragraphs) describing how the burning of fossil fuels contributes to global warming and climate change. Your essay should include the following:
1. A definition and examples of fossil fuels.
2. Examples of greenhouse gasses.
3. Examples of human behaviors that contribute to the greenhouse effect.
4. The connection between the greenhouse effect and global warming.
5. The connection between global warming and climate change.
6. The effects of climate change on the environment.
7. Examples of actions we can take to slow or reverse climate change.
