They can even cause more or less rain. Now, scientists say these tiny particles can effect global climate. Find out why. We hear a lot about the potential for greenhouse gases to lock in heat from the sun, making our planet warmer. They directly impact the climate because they scatter and absorb sunlight, and sunlight is the source of energy for the climate engine.
Aerosols can reflect sunlight, much like clouds.
They can also indirectly affect clouds. It can reduce the amount of precipitation. Special thanks to NASA 's Earth Science Enterprise. I'm Deborah Byrd for Earth and Sky.
