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 are greenhouse gases?

Back

Greenhouse gases are gases in Earth's atmosphere that trap heat. The most common greenhouse gases include carbon dioxide (CO2), methane (CH4), and nitrous oxide (N2O).

Front

What is the primary human activity that contributes to climate change?

Back

The primary human activity that contributes to climate change is burning fossil fuels, such as coal, oil, and natural gas.

Front

How does carbon dioxide affect the Earth's temperature?

Back

Carbon dioxide is very effective in trapping heat near the Earth's surface, contributing to the greenhouse effect and global warming.

Front

What is global warming?

Back

Global warming is the long-term heating of Earth’s climate system due to human activities, primarily the emission of greenhouse gases.

Front

What evidence supports the occurrence of global warming?

Back

Evidence of global warming includes rising global temperatures, melting ice caps, and increasing sea levels.

Front

What trend has been observed in atmospheric carbon dioxide levels since 1960?

Back

Atmospheric carbon dioxide levels have increased steadily since 1960.

Front

What is the role of power plants in climate change?

Back

Power plants generate electricity primarily by burning fossil fuels, which releases greenhouse gases into the atmosphere, contributing to climate change.

Front

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 and thus warming the planet.

Front

What are some consequences of climate change?

Back

Consequences of climate change include more frequent extreme weather events, rising sea levels, and disruptions to ecosystems.
