Carbon dioxide is a big deal. It’s responsible for about half of global heating. But what about the other half? There’s actually good news here: Nearly half of the temperature increases driving climate disasters come from super pollutants, most of which don’t stay in the atmosphere for nearly as long as carbon dioxide — which can last for centuries. Methane, for example, is about 80 times more potent at warming the climate than car...

There’s so much hard and heavy news out there right now, climate related and not. It feels like decades of progress is being lost. But — good news! — there are many solutions that can be deployed right now. This week we’re featuring conversations with three big thinkers who are bringing those solutions to light and showing why — even when times seem at their worst — they have no room for doom.

In January, congestion pricing went into effect in New York City. The policy’s implementation took decades; along the way, multiple moments suggested that it wouldn’t happen at all. Now, drivers entering Manhattan south of 60th Street during peak hours are required to pay a toll. Meanwhile, other cities like San Francisco are considering a similar initiative. But Trump opposes New York’s plan. Governor Hochul and state policy leade...

“In the course of saying no with their bodies, they were met with more violence… including moms who were carrying babies on their backs and were pushed to the edge of the river — and had to choose the river.” That’s Abby Reyes, author of “Truth Demands: A Memoir of Murder, Oil Wars and the Rise of Climate Justice.” In today’s episode, she shares deeply emotional stories of the price paid by environmental defenders. And she also sha...

Would you stand up against a giant corporation to stop toxic chemicals from harming your town’s water? Could you get policy enacted to cut emissions affecting people living in your state’s “diesel death zone?” How would you launch a global campaign to stop the construction of a new port threatening marine life on your island?
Every year, the Goldman Environmental Prize is awarded to six grassroots environmental heroes from around ...

About fifty years ago, multiple environmental disasters forced a reckoning with how we care for the Earth. President Richard Nixon signed numerous environmental protection bills into law in the 1970s, including what is considered to be the nation’s green Magna Carta: the National Environmental Policy Act (NEPA).
Among many other moves to eliminate or weaken federal environmental regulations and laws, the Trump administration is ...

Climate progress is stalling at the federal level, making local action more critical than ever. “In an increasingly urbanized world, cities must play the leading role in achieving our climate goals,” says San José Mayor Matt Mahan.
But what does that look like in practice? What role can cities play in accelerating the transition to a fully electrified economy across all sectors? And how does he plan to secure funding in uncertain...

It’s so easy to spiral into a climate doom loop. But solutions to the crisis are out there! Even as federal action stalls, states, local organizers and innovators across the U.S. are charging ahead with climate progress. What responsibility does the media have in elevating the solutions that exist and are working? And how can artists help reframe the climate conversation and shift the narrative from foregone conclusion to a reimagi...

Rep. Jared Huffman has represented California’s 2nd District — from the Golden Gate Bridge to the Oregon border — for over a decade. During that time, he has championed climate issues and fought to protect California’s public lands, prevent offshore drilling, pushed for financial institutions to divest from fossil fuels, and introduced legislation to tackle plastic pollution.
Now, turmoil in the federal government is putting all t...

Summer is coming soon, and for many that means vacation. While traveling far and wide can be an amazing experience, the carbon cost of traveling is significant. But what if we could rekindle a sense of awe in our own neighborhoods?
After years of extreme expeditions all over the world, adventurer Alastair Humphreys spent a year exploring the detailed local map around his home. His new book “Local” is an ode to slowing down, as wel...

Pope Francis was also a climate leader. In honor of his passing, this bonus episode revisits a Climate One episode from 2015 that focused on the Pope's views on climate and humanity.

Since its creation under President Richard Nixon in 1970, the U.S. Environmental Protection Agency has worked to reduce pollution and toxic exposures to ensure that Americans have clean air, clean water and clean soil. The EPA has also sought to reduce emissions to address climate change. Now that the Trump administration is in power, the EPA is being threatened with a 65% reduction in their budget.
In addition to EPA cuts, the ne...

More than 3 billion people rely on seafood as a primary source of animal protein. But waters are warming, and fish are moving. Are those fish, and the communities that have relied on them for centuries, in trouble?
We go around the world, from the rocky shores of New England to the picturesque island of Niue, to investigate how three popular fish are doing. Along the way, we meet people who are protecting and regrowing these fish p...

In a previous Climate One episode, we discussed the good, the bad, and the ugly impacts of artificial intelligence. But AI isn’t going away. Humans rarely give up a nifty new tool unless something better comes along. AI’s share of energy consumption is enormous, and the Department of Energy estimates that data center energy demands will double or even triple in just the next three years. Demand on fresh water is at least as big and...

It’s no secret that President Trump is not a fan of wind energy. As a matter of fact, he signed an executive order on his first day back in office that paused leasing for any new or renewed offshore wind energy projects and required the re-evaluation of all wind projects. This has thrown uncertainty into the entire industry, which already had supply chain and local opposition issues even before the new administration took office.

A third of Americans say that they've skipped food, medicine, or something else to be able to afford their energy bills. Much of the increase in the cost of electricity is driven by rising demand from artificial intelligence and data centers, industrial onshoring and hotter temperatures.
How does your electricity bill get calculated, and who’s in charge of setting those rates? Does public power serve consumers better than investor...

Who’s responsible for climate change? Fossil fuel companies would like us to believe it’s all of us as individuals (after all, BP invented the idea of the personal carbon footprint). But many large corporations bear at least as much of the blame. And for a decade or so, there was a push for every company to disclose its own emissions — a kind of corporate carbon footprint — and “sustainability” became the word of the day. But corpo...
