The Earth's climate has often changed very slowly over thousands of years. However, Earth's climate has started to change much faster than ever before since the Industrial Revolution. The effects of a changing climate are already starting to show and scientists are starting to understand what's going on. Climate change is mostly caused by the greenhouse gases that are released when we use fossil fuels (gasoline and heating oil). Now that we know this, we can take action to reduce our energy use and greenhouse gas emissions.
