What are greenhouse gases?

Back

Greenhouse gases are gases that trap heat in the atmosphere, including carbon dioxide (CO2), methane (CH4), and nitrous oxide (N2O).

How do greenhouse gases contribute to global warming?

Back

Greenhouse gases trap heat in the atmosphere, preventing it from escaping into space, which leads to an increase in Earth's average temperature.

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.

What impact does deforestation have on greenhouse gas levels?

Back

Deforestation increases greenhouse gas levels because trees absorb CO2; when they are cut down, the stored carbon is released back into the atmosphere.

What role do oceans play in the greenhouse effect?

Back

Oceans absorb a significant amount of CO2 from the atmosphere, but increased temperatures can reduce their ability to do so, exacerbating global warming.

What is the relationship between carbon dioxide levels and temperature?

Back

Higher levels of carbon dioxide in the atmosphere are associated with higher global temperatures due to the enhanced greenhouse effect.
