Working Science: What to Know about Geoengineering
What to do about the excess CO2 in our atmosphere that will remain for hundreds of years --even as we transition to renewable energy? To reduce the inevitable climate damage, we have to find a way to deal with that long-term CO2. Various "solutions," commonly known as types of geoengineering, have been proposed. Here, Professor 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.
