What role do aerosols play in climate change?

Back

Aerosols can cool the atmosphere by reflecting sunlight away from the Earth, but they can also contribute to warming by affecting cloud formation.

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 back into space, thus warming the planet.

Front

What human activities contribute to climate change?

Back

Human activities such as burning fossil fuels, deforestation, and industrial processes contribute to the increase of greenhouse gases in the atmosphere.
