ENCORE: Gloria Walton and Wawa Gatheru Believe in Grassroots Change, Not Just Charity
Those standing up to climate and environmental injustice face challenges they weren’t seeing a year ago. But Gloria Walton, head of The Solutions Project, sees a bigger picture:
“ The reality is that the same systems that created the climate crisis, whether that's colonialism, white supremacy, racism, and the patriarchy, those are the same ones that have harmed communities of color for generations,” she says. Her organization has channeled tens of millions of philanthropic dollars to grassroots efforts that build community resilience.
Black Girl Environmentalist founder Wawa Gatheru is helping more Black girls, women, and gender-expansive people enter and lead in the climate space. She says the climate fight has shifted from education to action, with over 70% of Americans now understanding that climate change is real. So what should this 'action phase' look like?

ENCORE: Solar Power to the People
At this moment, the cheapest way to create electricity is by pointing a solar panel at the sun. That’s good news for the climate. It’s also good news for communities who want to take control of their own electricity generation.
In the heart of Brooklyn, UPROSE is helping to build a solar project that will be owned by the community, provide jobs, and help residents bring down their energy costs. In Puerto Rico, where hurricanes have devastated the power grid, community members are building solar microgrids to provide reliable electricity as the utility has proven they cannot. Meanwhile in conservative rural Virginia, Energy Right is helping farmers and rural communities adopt solar projects, touting a free market message about energy independence and security.

This Year in Climate: 2025
2025 has been a doozy in so many ways. And climate news has been no exception. Climate One hosts Ariana Brocious and Kousha Navidar look back at what the year has meant for climate progress: the good, the bad, the ugly — and the joyful.
According to the World Meteorological Organization, 2025 will go down as one of the top three warmest years in the 176-year observational record. Climate-change-fueled extreme weather continues to wreak havoc on communities across the world. And yet, it’s not all bad news. As Bill McKibben points out, we now live on a planet where the cheapest form of energy basically comes from pointing a piece of glass at the sun. And globally, renewable energy surpassed coal for the first time ever.
Despite the federal government’s attacks on climate science and policy, local climate action is still happening across the country and globe, and each of us holds power to make change.

Jonathan Foley: 2025 Schneider Award Winner
Project Drawdown is the world’s leading science-based guide to climate solutions. According to Jonathan Foley, Project Drawdown’s Executive Director, they aim to be the Consumer Reports for climate change. “We synthesize every paper ever written in science, engineering, technical, economic literature, all the data, and bring it together and say, ‘Hey, does this actually work? And if so, how much would it cost? And how long would we have to wait for it?’”
Foley is not just an expert on the intricacies of hundreds of potential climate solutions; he’s also the winner of the 2025 Stephen H. Schneider Award for Outstanding Science Communication, and an expert at explaining complex ideas in easily digestible terms. As he said on a past Climate One episode, “The great news about addressing climate change is we also build a better world in the process. Imagine going to the doctor and they're like, ‘Wow, you're really sick and I'm gonna give you this medicine, and its side effects are, you're gonna feel better.’ Climate solutions are like that.”

Faith in Climate Progress
It’s been ten years since Pope Francis issued his landmark encyclical on climate and caring for our common home, Laudato Si’. With the election of the new Pope Leo XIV, many are hopeful he will follow in Francis' path.
Three-quarters of the global population follow a major religion. And the Catholic Church is far from alone among religious institutions in its directives to care for creation. A few years after Laudato Si, Muslim leaders issued Al-Mizan, which restates principles from the Quran on protecting nature in terms of meeting current challenges. Organizations like Interfaith Power and Light, the Jewish group Dayenu, the Hindu Bhumi Project, and the Buddhist Climate Action Network demonstrate the universality of creation care as central to religions worldwide.
Especially at a time when governments are failing to take meaningful action on climate progress, can faith traditions provide new paths forward?
Guests:
Celia Deane-Drummond, Director, Laudato Si' Research Institute; Senior Research Fellow in Theology at Campion Hall, University of Oxford
Rabbi Jennie Rosenn, Founder & CEO, Dayenu

ENCORE: Small Dollar, Big Impact
The climate doesn’t care where emissions cuts come from; what matters is that the world transitions to renewable energy quickly and cheaply. If it’s significantly cheaper to install solar panels in India than on a rooftop in California, then isn’t that where they should be built? Similarly, transferring money directly to local people with the greatest stake in preserving their land can have outsized impact in conservation. Where does a climate dollar go furthest?

Joe Manchin: Coal, Climate, and ‘Common Sense’
Joe Manchin grew up in the coal fields of West Virginia, the grandson of a miner and the son of a small-town grocer. His worldview was shaped by a place where energy isn’t an abstract policy debate; it’s the identity of the community and vital for economic survival. Manchin was portrayed as a bit of a villain in liberal circles for his role in blocking or slowing down Biden-era policy goals, including climate policy. Yet he was also the architect of the biggest climate legislation the country has ever enacted: the Inflation Reduction Act.
Now, in the midst of the Trump administration dismantling climate policy and basic political norms, Manchin is calling for a return to compromise and “common sense.”

Reports from COP30: Climate Talks in the Amazon
The UN climate convention known as COP30 is now underway in Brazil. As the nations of the world gather to discuss their efforts to rein in climate disruption, the facts are clear: we’re not doing enough, fast enough, to meet the Paris Agreement goal of limiting warming to 1.5 degrees Celsius above preindustrial levels. Climate-fueled disasters are increasingly impacting nearly every part of the world.
And in Belém, Brazil, near the heart of the Amazon rainforest where the conference is being held, organizers have promised that Indigenous voices will play a bigger role than in the past. They’ve also billed this as an “implementation COP” where past promises will be turned into action. What practical steps can we hope countries achieve in this year’s negotiations?

When Climate Work Comes at a Cost: Dispatches From the Upside Down
Human-caused climate change is fueling extreme floods, wildfires, rising seas, and record-breaking heat all around the world. At the same time, some of the most senior U.S. government officials and other powerful actors are actively defunding climate programs, dismantling research institutions, erasing decades of environmental data, and launching direct attacks on climate professionals.
This week’s episode is about what it’s like to be a climate scientist, researcher, or environmental professional trying to do meaningful work in a country with a government that increasingly doesn’t want it. Many have faced harassment, threats, or dismissal — or live in fear that their funding will be frozen or cut. How does it feel to do climate work not just in an era of climate denial, but of deliberate climate erasure?
Episode Guests:
Rachel Rothschild, Assistant Professor, University of Michigan Law School
Brent Efron, Senior Manager for Permitting Innovation, Environmental Policy Innovation Center
