Actions to combat climate change have been primarily focused on mitigation - limiting the amount of greenhouse-gas emissions in the atmosphere. But even with those efforts, the planet's temperature will continue to rise, leading to more extreme weather events. How will humanity adapt? Bill Gates, the co-founder of Microsoft, tells us why adaptation in agriculture is critical to feeding the world. We go to China to explore a new kind of “sponge city,” which is designed to absorb water. And we examine the peril and promise of solar geoengineering.  Hosted by Vijay Vaitheeswaran, The Economist’s global energy and climate innovation editor, with environment editor Catherine Brahic, and Oliver Morton, our briefings editor.   For full access to print, digital and audio editions as well as exclusive live events, subscribe to The Economist at economist.com/climatepod and you can sign up to our fortnightly climate newsletter at economist.com/theclimateissue.   See acast.com/privacy for privacy and opt-out information.
