What is contributing to climate change?
The main culprit is carbon dioxide.
Carbon dioxide (CO2) is a greenhouse gas which traps warmth.
It’s a naturally occurring gas. It’s produced by all sorts of things, from volcanoes to ocean life.
In moderate amounts, CO2 is fine. Plants breathe in carbon dioxide and convert it to oxygen and sugar, which are great for humans.
But since the industrial revolution, there has been another major source of carbon dioxide: fossil fuels.
Now there is too much carbon dioxide, and not enough plant life to get rid of it.
