Solar Geoengineering One Balloon at a Time? with Luke Iseman

In this Climate Chat episode, we talk with Make Sunsets co-founder Luke Iseman about his approach to "cooling the Earth" by launching balloons into the stratosphere with tiny amounts of sulfur in them. While purposefully putting sulfur into the stratosphere at large scale (called solar geoengineering or solar radiation management (SRM)) is proposed as way to offset global warming, many in the SRM community are opposed to Make Sunsets' "rouge" approach. Before co-founding Make Sunsets, Luke founded a number of companies in the agriculture and smart home spaces and he was Director of Hardware at Y Combinator. Luke holds a BS in Economics from The Wharton School.
