So much carbon has been put into the atmosphere that climate change modelers assume we will develop technologies for sucking carbon out of the atmosphere. On the current trajectory of carbon emissions, the risks of global warming are so severe that some scientists are even researching ways of blocking incoming sunlight to cool the earth. But these “climate engineering” approaches to curb climate risks have risks of their own. In this talk, science writer Holly Jean Buck will discuss the possibilities of climate engineering approaches to limiting or reversing climate impacts, and what they could mean for human communities and our oceans.

Buck is a researcher at UCLA’s Institute of the Environment and Sustainability. She completed a Ph.D. on environmental sociology and emerging technologies at Cornell University.
