  • Sucking the carbon out of the sky

    Sucking the carbon out of the sky
    Apr 28 2021
    Most of our efforts to fight climate change, from electric cars to wind turbines, are about pumping fewer greenhouse gases into the atmosphere. But what if we could pull out the gases that are already there? Akshat Rathi, a reporter at Bloomberg with a doctorate in chemistry, knows more about this technology, called “direct air capture,” than just about anyone. He follows companies like Carbon Engineering and Climeworks that are trying to figure out how to take regular air and pull carbon dioxide out of it. If their plans work, they could mean a world with net negative emissions: less carbon in the sky than there is right now, and a cooler planet. But his reporting has also highlighted how elusive carbon capture can be, and how tricky it can be to make the tech work at an affordable price. Rathi and Vox’s Dylan Matthews discuss how direct air capture works, how it’s different from capturing carbon at a fossil fuel plant, and the struggles of one direct air capture company in particular.

  • Should I still have kids if I’m worried about climate change?

    Should I still have kids if I’m worried about climate change?
    Apr 21 2021
    Climate scientist Kimberly Nicholas co-led a study that showed the single most effective thing an individual can do to decrease their carbon footprint is have fewer kids. Despite that finding, she still says that people who really want to have kids should go ahead with their plans. She explains how she squares that circle to Vox’s Sigal Samuel, and the two discuss how to think about the decision to have kids or not and how to make meaning in a warming world.

  • Engineering our way out of the climate crisis

    Engineering our way out of the climate crisis
    Apr 14 2021
    In an ideal world, cutting carbon emissions would be enough to stop global warming. But after dithering for decades, the world needs a back-up plan. Kelly Wanser is the leader of a group called SilverLining that works to promote research into what it calls “solar climate intervention.” Also called “solar geoengineering,” this approach involves putting particles into clouds that reflect back the sun, directly cooling the earth. It’s a novel and potentially hazardous policy — but one that Wanser and other experts argue could hold a lot of promise as the world braces for catastrophic climate impacts. Wanser and Vox’s Dylan Matthews discuss how solar climate intervention works, how it could be implemented, and where it fits in with the goal of cutting emissions. References: Kelly Wanser is the executive director of SilverLining. You can find more information at Silverlining.ngo, including its 2019 report on climate intervention research. You can also hear more from Wanser in her 2019 TED Talk.

  • Unexplainable

    Unexplainable
    Mar 16 2021
    Unexplainable is a new podcast from Vox about everything we don’t know. Each week, the team looks at the most fascinating unanswered questions in science and the mind-bending ways scientists are trying to answer them. New episodes drop every Wednesday. This episode: Scientists still don't know how the sense of smell works. But they're looking at how powerful it is — dogs can actually sniff out cancer and many other diseases — and they're trying to figure out how to reverse-engineer it. In fact, one MIT scientist may have built a robot nose ... without completely understanding how his invention works.

  • Rethinking meat

    Rethinking meat
    Nov 4 2020
    How can we convince people to change their relationship with meat? Melanie Joy has been grappling with this question for a long time. To answer it, she takes us back to other points in history when new technology helped make social change palatable. She digs into how the invention of the washing machine and other household appliances, for example, helped make feminism easier to imagine. Then, she looks to the future, at our latest meat technologies — plant-based meat and lab grown meat — and asks: Could they make it easier for us to move away from meat altogether? Further listening and reading: Joy’s books, Powerarchy: Understanding the Psychology of Oppression for Social Transformation and Why We Love Dogs, Eat Pigs, and Wear Cows. Vox’s Ezra Klein interviewed Joy for an episode of The Ezra Klein Show in 2018. Hear that interview and read her book recommendations here. We always want to hear from you!

  • Can we raise better beef?

    Can we raise better beef?
    Oct 28 2020
    Beef cattle take a huge toll on the environment. In Brazil, a huge chunk of greenhouse gas emissions comes from ranching alone. And a California-sized chunk of the Amazon rainforest has been cut down to provide land for these cattle to graze on. But one man, living on the edge of the Amazon rainforest, has a potential solution. In a series of small pilot projects run in his own small town, he’s demonstrated that he can work with ranchers to make their land healthier and more sustainable, so they don’t have to slash and burn more forest. He’s also shown that, by making the land greener and the cows healthier, he can dramatically reduce emissions from ranching. Further listening and reading: Christina Selby’s story about Vando Telles’s company can be found at Scientific American. Vox video has an in-depth explainer on deforestation in the Amazon and on the invasion of indigenous land in Brazil. Vox video also has an explainer on why eating beef speeds up climate change. Vox’s Umair Irfan traveled to Brazil last year to report on deforestation and climate change. We always want to hear from you! Please send comments and questions to futureperfect@vox.com.

  • How to prevent a factory farmed pandemic

    How to prevent a factory farmed pandemic
    Oct 21 2020
    What if the next pandemic comes, not from wet markets overseas, but from our own factory farms? Martha Nelson, who studies viruses at the NIH, says we are playing Russian roulette with potentially dangerous influenza strains on our pig farms. In this episode, we explain what makes these giant farms so likely to breed the next pandemic virus — and spread that virus into the world. And then, we look at solutions — from creating a virus-resistant pig, to developing a universal vaccine, to changing the systems we have for raising meat itself. Further listening and reading: Sigal Samuel wrote an in-depth explainer on the pandemic risks of factory farms earlier this year. She’s also written about “wet markets.” The Vox video team also made an explainer video on the same subject. For more on how viruses can spread in the pig population, Martha Nelson has an excellent paper “When Pigs Fly.” The Food and Agriculture Organization of the United Nations wrote a 2013 report on the health risks of factory farming. Sonia Shah’s book Pandemic is a great primer on how pandemic strains arise. We always want to hear from you! Please send comments and questions to futureperfect@vox.com.

  • These bacteria wear chicken shoes

    These bacteria wear chicken shoes
    Oct 14 2020
    Right now, we can fight off a wide range of bacterial infections using antibiotics. But those antibiotics are becoming increasingly ineffective, and antibiotic use on factory farms is partially to blame. In this episode, Lance Price and Cindy Liu, two public health researchers, explain that we give animals a steady dose of antibiotics in their feed, hoping to stave off disease in cramped, unsanitary conditions. But as a result, the bacteria in these animals develop resistance to antibiotics. But they have some suggestions for how we could make our antibiotics last. Further listening and reading: Sigal Samuel has written in depth about the antibiotic risks posed by our factory farms. Liu and Price’s full study is worth a read, as is this Wired writeup of its findings. The episode mentions some of the work that Canada and Denmark have done to combat this resistance problem. It also digs into the use of the antibiotic Colistin in Chinese farms, and the subsequent spread of resistance. We always want to hear from you!
