What are greenhouse gases?

Back

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

How does global warming affect ocean levels?

Back

Global warming causes ocean levels to rise due to the melting of ice caps and glaciers and the thermal expansion of seawater as it warms.
