More than perhaps any other state, Hawaii has major incentives to decarbonize. Imported oil accounts for about 90% of Hawaii's total energy consumption, and electricity prices are more than three times the national average. So it may not be surprising that Hawaii was the first state in the nation to set a 100% renewable energy goal by 2045. But that’s a hard goal to achieve, especially given the realities of geographic isolation and the costs of importing fuel and materials. 

Hawaii Governor Josh Green is bullish about the island state’s decarbonization and wants all options on the table. That includes making liquified natural gas part of the mix, along with solar, wind, and geothermal. His administration passed the first “green fee” which imposes a tax on Hawaii visitors and is expected to generate $100 million for climate resilience projects. What can we learn from Hawaii’s decarbonization process?

Food loss and waste account for up to 10% of global greenhouse gas emissions and cost $1 trillion annually, according to the United Nations. About a third of all food grown on the planet gets wasted, rather than eaten. In developing countries, waste usually occurs between the field and the store, due to poor infrastructure, lack of refrigeration, and broken supply chains. In rich countries, most waste happens after food reaches the store, where consumers don’t buy imperfect food – or buy too much and toss what they don’t get around to consuming. How much pollution, deforestation and starvation could be reduced if we got this problem under control? And how can new tech, including AI, be brought to bear on the problem?

While the federal government has all but abandoned trying to address the climate crisis, cities around the world are stepping up. C40 is an international network of 97 cities representing 920 million people and 23% of the world’s economy. Almost three out of four of these cities have already peaked their emissions. Here in the U.S., Climate Mayors is a bipartisan network of nearly 350 municipal leaders, representing 48 states and more than 70 million Americans. How are cities innovating on reducing emissions, adapting to increasing climate risks, and — perhaps most importantly — sharing their knowledge?

Rising electricity rates across the country are adding pressure to families and businesses already dealing with inflation in other aspects of their lives. Most Americans get their power from a utility that needs to turn a profit for its investors. And people are fed up with the status quo.

“Across the country, the utilities have just gotten greedy and are asking for more than they need,” says Arizona Attorney General Kris Mayes. 

Some communities are considering cutting out the profit motive for utilities, taking on the complicated and expensive prospect of moving to public power. But switching from an investor-owned utility to public power is an uphill battle. What are other strategies for reining in corporate greed and making electricity more affordable?

Congress approved billions for federal grants and programs through the EPA during the Biden administration. Those dollars were meant to help disadvantaged communities and fund community resilience projects, public health programs, and initiatives to reduce energy insecurity on tribal lands. But just as these projects were getting underway, the Trump administration froze many of the grants, put others under indefinite review, or canceled them outright. 

Now, some of the groups that were awarded federal funds have banded together and are suing the federal government for the money they’re owed. Others are seeking alternative funding streams. In this episode, we speak with people whose projects are on hold, but who continue to serve their communities.

It’s been an unusually warm and dry winter across the west, and that’s bad news for the seven states and 40 million people that rely on water from the Colorado River. The water flowing into the river from snowmelt and rain is dwindling, partly because of climate change. The basin's two major reservoirs are at historic lows, and without a sudden influx of snowstorms, streamflow forecasts for the coming year aren’t looking good. That adds stress to an already drought-stricken region where negotiations on how to share the river’s water in the future are tense and stalled out. 

“We’re at a point where we have to make some serious long-term adjustment of expectations. In other words, people need to agree to take a lot less water than they've been counting on. And that is always really hard when water is scarce,” says Sarah Porter, director of the Kyl Center for Water Policy at Arizona State University.

The federal government has given states a deadline of Feb. 14th to reach an agreement, after which the Bureau of Reclamation commissioner could divvy up the water between states as it deems fit. It’s already released its draft environmental impact statement with possible alternatives.

What’s led to this point of crisis? What is keeping states from reaching agreement? And what will the cities, farmers and industries that depend on the river do as climate change leads to a lower volume of water in an increasingly hotter and drier future?

On January 3, U.S. forces captured Venezuela’s president, Nicolás Maduro, and his wife, and flew them to New York to stand trial for drug trafficking and narco-terrorisim. At the same time, President Trump has not been shy about stating his other motivation for intervening in the country: Back in December, he said, “We had a lot of oil there. As you know they threw our companies out, and we want it back." So what are the geopolitical ramifications of these actions?  And in a world increasingly powered by renewable energy, could fossil-fueled conflicts become a thing of the past?

As the planet warms, the story of climate change is increasingly becoming a story about human health. Rising temperatures, wildfire smoke, flooding, and shifting disease patterns are no longer distant threats; they are everyday realities. The climate crisis is reshaping health care systems, exposing inequalities, and forcing doctors and policymakers to rethink some of their practices. Medical schools are beginning to adopt climate as part of their curricula, yet such education is widely variable across the country. So what policy and system changes might help address both the climate and health crises at the same time?

We’re only about a month into 2026, and already so much has happened — from the Trump administration’s forcible removal of Venezuela’s president to the US pulling out of the UN Framework Convention on Climate Change… It’s easy to get caught up in the headlines of the moment and lose sight of the big picture. 

But important developments are happening in sectors like agriculture and renewable technology that don’t break through the noise to the extent they deserve. So, what should we be watching in 2026?

Agriculture is directly responsible for 10 percent of U.S. greenhouse gas emissions, and farmers and ranchers face growing climate impacts every day, from more severe storms to intense droughts, making it harder to grow food. 

The non-partisan Congressional Budget Office estimates emissions from the agriculture sector will modestly increase over the next 30 years. Yet the Trump administration is slashing programs that help reduce emissions, feed people, protect farmworkers and animals and sensitive lands. In addition, the Trump administration’s tariffs and trade wars have affected the cost of machinery and sales of major crops. What will these changes mean for our national food system? How are farmers weathering these impacts? And where are people building resilience regardless of federal policy?
