How the Atmosphere Affects Climate Change - Professor Dan Cziczo - MIT - MIT Club of Northern California
What are the roles of greenhouse gases, small particles and clouds?
It has been known for over a century that greenhouse gases such as carbon dioxide and methane warm the planet by trapping heat. What is not as well known is that particles can cool the planet by reflecting sunlight into space and by acting as the seeds on which clouds form. Particles and clouds are also of contemporary interest because it has been suggested they might affect climate by interacting with cosmic rays or be used to manipulate the Earth’s temperature.

Dan Cziczo is an atmospheric scientist interested in the interrelationship of particulate matter and cloud formation. His research utilizes laboratory and field studies to elucidate how small particles interact with water vapor to form droplets and ice crystals which are important players in the Earth’s climate system. Experiments include using small cloud chambers in the laboratory to mimic atmospheric conditions that lead to cloud formation and observing clouds in situ from remote mountaintop sites or through the use of research aircraft. Dan holds a bachelor’s degree from the University of Illinois (Urbana-Champaign) and Masters and PhD degrees from the University of Chicago.
