Kgnu - How On Earth

Hacking the Planet (start time: 10:24): It’s tough to wrap one’s mind around just how monumental and consequential the problem of climate change is. So dire that scientist and engineers for years have been exploring ways to “hack” the planet--to manipulate the global climate system enough to significantly reduce planet-warming gases or increase the Earth's ability to reflect solar radiation. This audacious scheme, called geoengineering, only exists because many scientists think that human behavioral change, industry regulations, international treaties and national legislation, have not done enough -- can not do enough – to keep us from careening toward climate catastrophe. Our guests today have given this huge challenge a lot of thought and some research. Dr. Lisa Dilling is an associate professor of Environmental Studies at CU Boulder and a fellow at the Cooperative Institute for Research in Environmental Sciences, or CIRES. Dr. David Fahey is a physicist at the National Oceanic and Atmospheric Administratio
