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, especially the burning of fossil fuels, have accelerated these changes.

Front

What is the greenhouse effect?

Back

The greenhouse effect is the warming of the Earth's atmosphere caused by the trapping of heat from the sun by greenhouse gases like carbon dioxide and methane.

Front

What are greenhouse gases?

Back

Greenhouse gases are gases in the Earth's atmosphere that trap heat. The main greenhouse gases are carbon dioxide (CO2), methane (CH4), nitrous oxide (N2O), and water vapor.

Front

How do human activities contribute to climate change?

Back

Human activities such as burning fossil fuels, deforestation, and industrial processes increase the concentration of greenhouse gases in the atmosphere, leading to global warming.

Front

What is the impact of melting glaciers and polar ice caps?

Back

Melting glaciers and polar ice caps contribute to rising sea levels, which can lead to coastal flooding and loss of habitat.

Front

What are some extreme weather conditions caused by climate change?

Back

Extreme weather conditions caused by climate change include flooding, heat waves, hurricanes, and droughts.

Front

What is the role of carbon dioxide in climate change?

Back

Carbon dioxide is a major greenhouse gas that traps heat in the atmosphere, contributing to the greenhouse effect and global warming.

Front

What is the difference between weather and climate?

Back

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

Front

What is deforestation and how does it affect climate change?

Back

Deforestation is the clearing of forests for agriculture or urban development. It reduces the number of trees that can absorb CO2, increasing greenhouse gas levels in the atmosphere.

Front

What is the significance of the ozone layer?

Back

The ozone layer protects the Earth from harmful ultraviolet (UV) radiation from the sun. It is different from greenhouse gases, which trap heat.
