As the dog days of summer shorten, and our vacations wind down, we dig into the Sea Change Radio archives to revisit two climate-related conversations. First, we discuss the issue of a warming planet with Andrea Thompson, a science reporter and associate editor at Scientific American. We look at how people and policymakers are trying to cope with the rising temps and examine how different parts of the globe are being affected. Then, we speak to David Messina, the CEO of Rumin8, an Australian-based startup that is hoping to transform the cattle industry. The company’s main product is a lab-grown feed additive that is designed to significantly reduce methane emissions in ruminants like cattle and sheep. We discuss the problem that Rumin8 is trying to solve and talk about the company’s business strategy and hurdles it faces.
