Atmospheric Tipping Points

THU, SEP 3, 2020 (34:24)

Dr. Cziczo explains the difference between millions of years of natural warming cycles and the more recent anthropogenic warming caused by the production of more CO2. He discusses the implications of atmospheric CO2 buildup and the limitations of geoengineering and sequestration as solutions to this problem.

Daniel Cziczo is professor and head of the Department of Earth, Atmospheric, and Planetary Sciences at Purdue University.

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.
