What is climate change?

Back

Climate change refers to significant changes in global temperatures and weather patterns over time, primarily caused by human activities such as burning fossil fuels, deforestation, and industrial processes.

What are greenhouse gases?

Back

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

Front

Which gas is NOT a greenhouse gas?

Back

Nitrogen (N2) is not a greenhouse gas.

Front

What is the primary cause of the increase in atmospheric CO2 levels since the 1960s?

Back

The primary cause is human activities, particularly the burning of fossil fuels for energy and transportation.

Front

What was a significant event that led to increased CO2 levels in the atmosphere?

Back

The Industrial Revolution in the 1800s led to a significant increase in CO2 levels due to the rise of factories and the use of coal.

Front

What is the impact of plastic pollution in oceans?

Back

Plastic pollution harms marine life, disrupts ecosystems, and can enter the food chain, affecting human health.

Front

Which country is known to cause the most plastic pollution in oceans?

Back

China is known to cause the most plastic pollution in oceans.

Front

What is global warming?

Back

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

Front

How does deforestation contribute to climate change?

Back

Deforestation contributes to climate change by reducing the number of trees that can absorb CO2, leading to higher levels of greenhouse gases in the atmosphere.

Front

What role do oceans play in climate change?

Back

Oceans absorb a significant amount of CO2 and heat, helping to regulate the Earth's climate, but they can also become warmer and more acidic due to climate change.
