Anthropogenic climate change poses serious risks. Yet even aggressive reductions of greenhouse gas emissions will most likely not be able to prevent harmful impacts, especially to already-vulnerable people, organisms, and ecosystems. Humans may be able to artificially cool the planet to counter climate change. What’s more, this “solar geoengineering” appears able to manage risks in ways that emissions reductions and adaptation to a changed climate cannot. At the same time, it poses environmental risks and governance challenges of its own. For example, solar geoengineering would be global in effect but seems technically feasible and inexpensive enough that many states—or perhaps even nonstate actors—could implement it on their own, regardless of any international consensus. How can its potential be explored without catalyzing new types of climate conflict? Dr. Jesse Reynolds will offer a brief introduction to solar geoengineering’s capabilities and limitations, with an emphasis on incentives and problem structure. After responses from our discussants, substantial time will be reserved for participants’ questions.
