Clouds cool the planet by reflecting solar energy back to space and also trap heat and radiate it back to Earth. In a Yale Environment 360 interview, physicist Kate Marvel discusses the double-edged effect clouds have on rising temperaturesClouds perform an important function in cooling the planet as they reflect solar energy back into space. Yet clouds also intensify warming by trapping the planet's heat and radiating it back to Earth. As fossil fuel emissions continue to warm the planet, how will this dual role played by clouds change, and will clouds ultimately exacerbate or moderate global warming?Kate Marvel, a physicist at Columbia University and a researcher at Nasa's Goddard Institute for Space Studies, is investigating the mysteries of clouds and climate change. In an interview with Yale Environment 360, she discusses what is known about the behaviour of clouds in a warming world (they are migrating more toward the poles), why strict controls need to be imposed on geoengineering experiments with clouds, and why she is confident that science and human ingenuity will ultimately overcome the challenge of climate change.
