Sarah Kapnick is the Head of Global Climate Advisory at J.P. Morgan—and before that, she spent more than a decade as a climate scientist in government, including serving as Chief Scientist at NOAA. In this episode of the Scientista Podcast, Dr. Sweta Chakraborty and Monica Medina talk with Sarah about what it means to translate climate science into real-world decision-making. Drawing on her experience across government and the private sector, Sarah explains how institutions think about climate risk, why uncertainty doesn’t stop action in financial markets, and how signals like insurance costs, infrastructure stress, and food systems are already reflecting climate impacts. The conversation spans climate risk in everyday life, housing and insurance, agriculture and soil health, extreme weather, and how long-term risks begin to shape near-term choices. It’s a grounded look at how climate knowledge moves—or fails to move—into systems that shape our future. A practical, clear-eyed discussion about risk, uncertainty, and why paying attention now matters. Thank you for listening! Learn more about Scientista here: www.scientista.world

What happens when 1.6 million moms decide clean air is non-negotiable? In this episode of the Scientista Podcast, we speak with Dominique Browning, founder of Moms Clean Air Force, about building one of the most powerful parent-led environmental movements in the country. From fighting methane pollution and plastic burning to defending the Clean Air Act, Dominique explains why protecting children’s health should be Mompartisan — beyond politics. We talk about how moms have become some of the most effective climate and public health advocates, why local action matters, what recent wins in states like New Mexico reveal about what’s possible, and how parents can get involved right now. This conversation is about clean air, kids’ health, and the growing power of parents who refuse to stay silent. Thank you for listening! Learn more about Scientista here: www.scientista.world

In this episode of the Scientista Podcast, we’re joined by former Secretary of Energy Jennifer Granholm and her senior advisor Karen Skelton for a wide-ranging conversation on energy, national security, and how policy actually gets made. We spend time on a lesser-known detail shaping the Greenland conversation: a 2021 law that restricts mining of ore linked to uranium, effectively limiting access to many critical minerals. Granholm shares insight into how this legal context may help explain recent political interest in Greenland—an angle largely missing from mainstream coverage. The conversation also explores clean energy affordability, utility regulation, global supply chains, and the importance of strong teams behind major policy decisions. Granholm and Skelton offer a candid look at what’s lost when complex energy and security debates get reduced to headlines—and why paying attention to the details matters. Thank you for listening!

Fear has dominated the way we talk about climate change for decades. But fear doesn’t motivate most people to act—it overwhelms them. In this episode of the Scientista Podcast, Sweta Chakraborty and Monica Medina are joined by Anne-Therese Gennari, known as the Climate Optimist, for a conversation about why fear-based climate messaging fails—and what works instead. Drawing on behavioral science and lived experience, we talk about how motherhood reshapes the way people think about risk, responsibility, and the future, and why mothers can be powerful drivers of climate action in their own communities. The episode explores climate communication through a human lens: how people make decisions under uncertainty, why proximity matters more than abstraction, and what changes when climate action starts close to home. This conversation is about communicating climate in ways that reflect how people actually think—and act. Thank you for listening! Learn more about Scientista here: www.scientista.world

Do we actually need billionaires? On this episode of the Scientista Podcast, Dr. Sweta Chakraborty speaks with Abigail Disney about extreme wealth, hoarding, and the cultural narratives that allow inequality to persist. Abigail has been outspoken for years about the harm caused by concentrated wealth, and in this conversation she explains why accumulation at the highest levels stops serving human needs and starts distorting systems meant to support society. They discuss how extreme wealth is often shielded from scrutiny, why philanthropy doesn’t resolve the underlying problem, and how stories about success and merit have been used to normalize levels of inequality that would once have been unthinkable.

In this episode, Dr. Sweta Chakraborty and Monica Medina sit down with Dr. M. Sanjayan—ecologist, award-winning storyteller, and former CEO of Conservation International—for a conversation about what it takes to lead in one of the toughest, most important sectors on earth. Sanjayan reflects on a childhood spent exploring the forests of Sierra Leone, the scientific rigor that shaped his career, and the mentors who opened doors when traditional pathways were limited. He also gives straight talk on today’s biggest conservation challenges—from the destabilizing impact of foreign-aid cuts to the urgent need for financial models that value nature as infrastructure, not afterthought. For emerging scientists and conservationists, his advice is both practical and energizing: build real scientific depth, find mentors who advocate for you, and keep the joy and curiosity that brought you into this work in the first place.

“AI will tell you to walk across the English Channel… it’s not intelligent. It is pattern recognition.” NRDC Chief Science Officer Dr. Ticora Jones joins the Scientista Podcast for one of our most candid conversations yet. Dr. Jones talks about what AI really is (and isn’t), the collapse of USAID under Trump’s second term, why global development work depends on genuine collaboration—not American saviorism—and how she helps her own organization slow down and learn together instead of getting swept up in hype. She also shares why she wants her seven-year-old daughter to grow up grounded in a sense of “I can,” how community sustains women and women of color in science, and why finding your people is essential when the world feels chaotic. If you care about science, public trust, or how we rebuild institutions that matter, this conversation is for you. Thank you for listening! Learn more about Scientista here: www.scientista.world
