You might have heard about climate change on the news, in the newspaper or at school. But what is climate change?
Our atmosphere is full of gases, like carbon dioxide, nitrogen, methane and oxygen. These are called greenhouse gases, and these gases are being made all the time. This has always happened, and having the right amount in our atmosphere helps to keep in enough of the sun's heat to warm the Earth. The problem is, too many of these gases are being trapped. Extra gases are made by things like the transport we use, farms and factories, and the energy we need to make technology work. They are holding in more of the sun's rays than ever before, heating up the planet (global warming).
Scientists have found that this build-up of gases is changing our earth's climate. This is climate change.
