In a little more than six weeks, Americans will cast their votes in a presidential election that has enormous stakes for the future of the planet. This week on Zero, Akshat Rathi sits down with energy and environment reporter Jen Dlouhy to talk about how Kamala Harris could advance US climate policy — and how Donald Trump could chip away at it. “Starting on day one, he's already said he intends to direct federal agencies to begin repealing and replacing climate regulations,” she says.

At this stage of the campaign, Harris’s plans are still somewhat opaque. But if elected, her administration is expected to keep quietly pushing forward policies passed under President Biden. “There's still tremendous work to get the IRA's programs running to get dollars flowing,” Dlouhy says. “The Treasury Department still hasn't finished writing rules for how people can claim tax credits under the law, including those governing hydrogen production and clean electricity. So there's just a lot of administrative work to be done to kind of unstick this process to accelerate deployment.”

Weather patterns have always had an impact on people and civilizations. Historians argue that El Niño may have contributed to the French Revolution, and climate variability could have led to weakening the Ottoman Empire. But as anthropogenic emissions make the planet hotter, faster, Berghof Foundation Executive Director Andrew Gilmour says the risk of conflict is growing. In the 30 years he spent working with the United Nations, Gilmour repeatedly saw how competition over resources such as land and water led to conflict, but he also sees opportunities for aligning peace-building with climate solutions. “The common solutions could be, for example, a solar powered irrigation scheme,” Gilmour tells Akshat Rathi. “It could be joint management of a wildlife reserve, it could be a desalination project.”

After years of research and development and billions in investment, autonomous flying taxis are finally poised to take off. Companies working on these pilotless vehicles have been quietly working on prototypes. In this bonus from The Big Take, Bloomberg reporter Colum Murphy takes a test flight in one of the first models operating in China, and his colleague Angus Whitley explains why it’s a make or break moment for the industry.

Plus: Hear a past episode episode of Zero about flying cars with Venkat Viswanathan, a professor at Carnegie Mellon University who has been working to create a battery that can power an aircraft on a trip over 200 miles.

Achieving net-zero carbon emissions is a massive challenge for every industry, but some have it harder than others. This week, Bloomberg Green senior reporter Akshat Rathi spoke with two Australian startups that are tackling carbon emissions in sectors whose carbon footprints are particularly intractable. Inspired by shark skin, MicroTau is creating a plastic film that makes airplanes more aerodynamic, reducing their fuel consumption. Novalith, meanwhile, is redesigning lithium battery manufacturing to make it cleaner. Both have received funding from the Clean Energy Finance Corporation in Australia. Rathi sat down with MicroTau founder Henry Bilinsky and Novalith Chief Executive Officer Steven Vassiloudis to understand the challenges their startups face and where they find optimism.

Before he founded the geothermal startup Fervo in 2017, Tim Latimer was a drilling engineer for the oil and gas industry — a job he loved. “Honestly, if it wasn't for climate change, I probably wouldn’t have ever changed my career,” he says this week on Zero. Now Latimer is applying his drilling know-how to Fervo’s wells, supercharging their energy production in the process. The company opened its first power plant in Nevada late in 2023, and is now in the process of opening another plant in Utah. Latimer and Akshat Rathi chat about opportunities in geothermal, the infernal permitting process, and why Fervo has its sights on expanding into Kenya, Indonesia, Turkey and the Philippines.

The “cold chain” that delivers our food is inconspicuous but vast. The US alone boasts around 5.5 billion cubic feet of refrigerated space; that’s 150 Empire State Buildings’ worth of freezers. Now, the developing world is catching up. On Zero, Nicola Twilley, author of Frostbite: How Refrigeration Changed Our Food, Our Planet, and Ourselves, discusses how refrigeration became so ubiquitous and what our reliance on it means for our palates and the planet.

This week on Zero, reporter Akshat Rathi sits down with Renee Salas, an emergency medicine physician at Massachusetts General Hospital and Harvard Medical School and a leading expert on the health impacts of global warming. The intersection of health and climate change is a growing area of research, and an increasingly urgent one: Heat deaths among seniors, for example, are projected to increase 370% by mid-century. But even the young and relatively healthy are at risk. “The take-home I want everyone to go away with is that we all are at risk for this,” Salas says, “especially as we get into more and more extreme conditions.”

Upgrading the grid for a net-zero world isn’t just a matter of building new infrastructure. Yes, miles of additional cables will be needed, as will more transformers, more substations and more engineers and technicians. But plenty of existing technology will also need to be updated. On the third episode of Zero’s grid series, TS Conductor founder Jason Huang discusses the material science breakthroughs that have enabled his company to create cables that have twice the conductivity of existing cables — and just as much strength.
