Climate change

Climate change is when the earth's temperature gets warmer and warmer over time. This happens because more heat-trapping gases like carbon dioxide (CO2) are being released into the air by people burning things like coal and oil. These gases act like a blanket over the earth and keep the heat from leaving. As the blanket gets thicker, it trap more of the sun's energy and gets even warmer, like when you put more blankets on your bed.
