The climate is changing all around us and it's heating up every year.
Greenhouse gases, including carbon dioxide, methane and water vapor, trap heat in the Earth's atmosphere and warm the planet. In general, the greenhouse effect is a good thing. Without greenhouse gases, the temperature on Earth would be too cold to support life.
Icebergs are melting and they are putting some animals in danger.
Oceans are rising which is causing houses and villages to flood and people are having to leave homes.
