In this 5:30 video, students learn how NASA uses a data-collecting sensor, Clouds and Earth’s Radiant Energy System, or CERES, to study clouds and make accurate measurements of energy leaving Earth. It explains that the surfaces on Earth absorb and reflect the Sun’s energy in different amounts and how that, plus greenhouse gases, can add up to global warming.
