Clouds are the clue for better climate predictions

Clouds are the clue for better climate predictions

Climate predictions are based on three components: greenhouse gas emissions, clouds and atmospheric aerosol particles, and solar variability. Scientists can accurately determine greenhouse gas emissions and variations of the sun, including sunspot cycles and variations in cosmic rays. However, clouds and aerosols are an area about which scientists are uncertain, because they do not fully know how aerosol particles form and how they affect clouds. Two new papers published in Nature on May 26 from a team at the CERN CLOUD experiment led by researchers from the Paul Scherrer Institute and Carnegie Mellon University’s College of Engineering and Mellon College of Science demonstrate how aerosol particles form, allowing for much more accurate climate predictions.
