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?

Nathaniel Stinnett: Climate Disruption Is a Homicide, Not a Suicide (Bonus Episode)
According to one recent survey, Americans think about climate change more than abortion, immigration, or gun violence. And yet, while they care deeply about the issue, they don’t see it as a political issue. When asked by the Environmental Voter Project what actions should be taken to rein in climate disruption, those surveyed suggest taking small, personal steps, like recycling, over broader, political action, as they do with other top-of-mind issues.
Where does this disconnect come from? And what will it take to shift the narrative from the personal to the political?

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?

Batteries Now Included
The Trump administration has taken aim at green energy, but one technology has largely been left untouched: batteries to store wind and solar electricity. California alone surpassed 13GW of battery storage last year, and Texas has become the fastest growing market for the technology. But producing batteries isn’t without its downsides, especially when it comes to mining the necessary raw materials. The upside is that those materials can be recycled and reused. If the recycling technology can reach scale and price targets, the environmental impact would drop significantly. And spent EV batteries could become a grid scale storage site even without breaking down the battery packs. How soon before renewables plus batteries can power our grid 24/7?
This episode features a reported piece by Camila Domonoske that was originally broadcast on NPR’s All Things Considered on July 10, 2024

Cause of Death: Air Pollution
In 2013, 9-year-old Ella Roberta died from a severe asthma attack. She became the first person in the United Kingdom (and possibly the world) to have “air pollution” listed as the cause of death on her death certificate. Her mother, Rosamund Adoo-Kissi-Debrah, founded the Ella Roberta Foundation and has become a global voice for clean air.
Globally, the World Health Organization says that air pollution is associated with 6 to 7 million premature deaths every year. Addressing the cause of these deaths would also go a long way to addressing climate disruption. And since talking about climate has become so politically fraught, should we reframe the conversation to focus on taking care of our air?
Guests:
Rosamund Adoo-Kissi-Debrah, Founder, Ella Roberta Foundation
Sheila Watson, Deputy Director, FIA Foundation
Susan Joy Hassol, Director, Climate Communication
Highlights:
(00:00) Intro

(08:00) Ella becomes first person to have “air pollution” listed as cause of death
(13:00) Rosamund’s work sharing Ella’s story and raising awareness about air pollution
(20:30) How poisonous transportation emissions are and policy tools to reduce them
(26:00) Economic development does not need to sit contrary to healthy air
(27:00) Dieselgate and the work of the True Real Urban Emissions initiative
(31:00) Extreme heat can make air pollution more deadly
(37:00) Why we shouldn’t use the term "climate change”
(43:00) Finding ways to connect with people on climate based on their priorities
(49:00) How to convey the seriousness of climate threats while also empowering people to feel that they can make a difference

Young People Are Bringing Climate To Court. And Winning.
We’re all feeling the effects of the fossil-fueled climate crisis, but young people will not let this threat to their future go unchallenged. They’re taking it to the courts. In the last year, youth plaintiffs have had notable legal successes in Montana and Hawaiʻi, challenging that those states were violating their constitutional rights in continuing to burn fossil fuels. In Hawaiʻi, the ruling compels the state department of transportation to quickly move to a zero-emission system.
But the biggest victory may have been outside of the U.S. The small island nation of Vanuatu led the charge to ask the International Court for Justice to grant a judgement on the legal obligation of countries to fight climate change. The judgment, released in late July, stated that countries do have a responsibility to address the climate crisis. Beyond their specific claims and remedies, these numerous cases ask: What do we owe our future generations, and how will we make good on those promises?
Guests:
Vishal Prasad, Director, Pacific Islands Students Fighting Climate Change
Julia Olson, Co-Executive Director & Chief Legal Counsel, Our Children’s Trust
Rylee Brooke Kamahele, Youth Plaintiff, Navahine v. Hawaiʻi Department of Transportation

Scorching Premiums: Climate Costs Hit Insurance Market
Climate disruptions and growing risk are upending insurance markets, leading many insurers to abandon parts of the country all together. Due to fires, floods and other extreme events, more and more homeowners are facing rapidly rising premiums or being dropped from their insurance plans altogether. Increasing numbers of homeowners are taking refuge in the state insurance plans of last resort, straining the program resources. For homeowners, whose house is often their biggest financial asset, this creates a huge financial risk.
So what should people do to evaluate climate risks and insurance availability during their housing search? And how can governments help insurers weather the increasing frequency of climate-induced disasters so they can continue to underwrite our homes?
Guests:
Rachel Cleetus, Senior Policy Director, Union of Concerned Scientists
Claire O’Connor, Los Angeles real estate agent and homeowner
Dave Jones, Director, Climate Risk Initiative at the Center for Law, Energy & the Environment, UC Berkeley

Trump’s Megabill Comes for the Clean Energy Transition
Three years ago, Congress passed President Biden’s Inflation Reduction Act, the largest investment in climate action in U.S. history. The IRA set in motion a sweeping set of investments in nearly every aspect of energy and climate, mostly in the form of subsidies and tax credits, to boost domestic production of electric vehicles, batteries and carbon-free energy. Those investments have flowed to every state, but the majority have landed in Republican-held districts.
In spite of that, Congressional Republicans nearly unanimously passed President Trump’s “Big, Beautiful Bill” which the president signed on July 4. The megabill guts nearly all the program funds allocated under the IRA and slashes incentives and credits for solar, wind, energy efficiency and electric vehicles — precisely at a time when we need to dramatically scale up those sectors to address climate change. Why did Republicans let this bill move ahead? And how much will it exacerbate the climate crisis in the coming decades?
Guests:
Katherine Hamilton, Chair, 38 North Solutions
Clayton Aldern, Senior Data Reporter, Grist
Lisa Jacobson, President, Business Council for Sustainable Energy
John Szoka, CEO, Conservative Energy Network
