Even when we achieve a ‘net-zero’ world, humankind may need additional methods to avoid the worst of climate change. Those methods have risks as well as rewards. Hence the title of Wake Smith’s new book Pandora’s Toolbox: The Hopes and Hazards of Climate Intervention. It is a compendium of possible climate ‘interventions’ (AKA geo-engineering technologies) that future generations may want to use to respond to a warming world. Listen in to hear the author discuss why it is important to think about the technology, governance and ethics of tools like “Carbon Dioxide Removal” now rather than leaving the problem to our children.
