Intro to Climate Change

Front

What is climate change?

Back

Climate change refers to significant changes in global temperatures and weather patterns over time. While climate change is a natural phenomenon, human activities have accelerated it, particularly through the release of greenhouse gases.

What is the greenhouse effect?

Back

The greenhouse effect is the process by which certain gases in Earth's atmosphere trap heat, preventing it from escaping into space. This effect is essential for maintaining the planet's temperature but can lead to global warming when enhanced by human activities.

What are fossil fuels?

Back

Fossil fuels are natural substances formed from the remains of ancient plants and animals. They include coal, oil, and natural gas, and are used as energy sources.

What is carbon dioxide?

Back

Carbon dioxide (CO2) is a colorless gas that is produced by burning fossil fuels and is a significant greenhouse gas contributing to climate change.

What is biofuel?

Back

Biofuel is a type of renewable energy derived from organic materials, such as plants and animal waste, that can be used as an alternative to fossil fuels.

What is the difference between weather and climate?

Back

Weather refers to the short-term atmospheric conditions in a specific place at a specific time, while climate is the long-term average of weather patterns in a region over a significant period.

What is global warming?

Back

Global warming is the long-term increase in Earth's average surface temperature due to human activities, primarily the emission of greenhouse gases.

What role do trees play in combating climate change?

Back

Trees absorb carbon dioxide from the atmosphere during photosynthesis, helping to reduce the amount of this greenhouse gas and mitigate climate change.

What is renewable energy?

Back

Renewable energy comes from sources that are naturally replenished, such as solar, wind, and hydroelectric power, and is considered more sustainable than fossil fuels.
