Show Notes Chapter Markers

Luke Iseman is the founder of Make Sunsets, a recently launched startup that is selling “cooling credits” on the promise that they will release sulphur dioxide into the stratosphere using weather balloons. In this episode, we discuss Make Sunset’s mission to “substantially lower global temperatures,” the details of their offering, the technical challenges for verifying their cooling credits, and the potential political repercussions of their efforts
