What To Know About Geoengineering

FRI, APR 22, 2016 (29:12)

What to do about the excess CO2 in our atmosphere that will remain for hundreds of years --even as we transition to renewable energy? The impact on Earth's climate is already obvious and will continue. To reduce the damage, we have to find a way to deal with that long-term CO2 in the atmosphere. Various "solutions," commonly known as types of geoengineering, have been proposed. Here, Professor Daniel Cziczo explains the CO2 problem and the three major types of geoengineering. We learn why the only viable approach is CO2 sequestration --pulling the CO2 out of the atmosphere.

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.
