Heating up: Here’s how climate change works

  • Burning fossil fuels such as coal and oil releases greenhouse gases into the air.
  • If too much of these gases go into the atmosphere, the Earth’s air temperature starts to rise. This is called global warming.
  • What the atmosphere is like determines the weather patterns on Earth. If the air gets too warm, it upsets the Earth’s climate. This is called climate change.
