Questions and Answers

What are greenhouse gases and why are they significant to global warming?

Greenhouse gases, such as carbon dioxide, methane, and nitrous oxide, are significant to global warming because they trap heat in the atmosphere, leading to an increase in Earth's temperature.

What human activities contribute to the increase of greenhouse gases?

Human activities like deforestation, burning fossil fuels, and agricultural practices contribute to the increase of greenhouse gases.

How does deforestation impact global warming?

Deforestation impacts global warming by reducing the number of trees that absorb carbon dioxide, which increases the concentration of greenhouse gases in the atmosphere.
