Clouds and Earth’s energy balance

‘Clouds, since they reflect sunlight sunlight back to space, can cool the Earth. And clouds also, on the other hand, can heat the planet in a greenhouse sense.’
– Bruce Weilicki

Bruce Wielicki of NASA is the principal investigator for NASA’s Clouds and the Earth’s Radiant Energy System (CERES) mission.

In this Clear Voices for Science podcast, Wielicki spoke with EarthSky’s Jorge Salazar about how clouds affect the energy Earth receives, keeps, and emits back to space – what scientists call Earth’s energy balance.

Our thanks to NASA‘s Terra Mission, helping us better understand and protect our home planet.
