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.

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 back into space. This effect is essential for maintaining the planet's temperature.

What are greenhouse gases?

Back

Greenhouse gases are gases that contribute to the greenhouse effect by absorbing infrared radiation. Major greenhouse gases include carbon dioxide (CO2), methane (CH4), and nitrous oxide (N2O).

How does carbon dioxide contribute to climate change?

Back

Carbon dioxide (CO2) is a major greenhouse gas that traps heat in the atmosphere. Increased levels of CO2 from human activities, such as burning fossil fuels, lead to global warming.

What is the role of power plants in climate change?

Back

Power plants that burn fossil fuels, such as coal, oil, and natural gas, release large amounts of carbon dioxide and other greenhouse gases into the atmosphere, contributing to climate change.

What is the stratosphere?

Back

The stratosphere is the second layer of Earth's atmosphere, located above the troposphere. It contains the ozone layer, which protects living organisms from harmful ultraviolet (UV) radiation.

Front

What is the ozone layer?

Back

The ozone layer is a region of Earth's stratosphere that contains a high concentration of ozone (O3) molecules. It absorbs the majority of the sun's harmful UV radiation.

Front

What are the effects of climate change on weather patterns?

Back

Climate change can lead to more extreme weather events, such as hurricanes, droughts, and heavy rainfall, as well as shifts in seasonal weather patterns.

Front

What is global warming?

Back

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

Front

What is renewable energy?

Back

Renewable energy is energy that is generated from natural processes that are continuously replenished, such as solar, wind, hydroelectric, and geothermal energy.
