The new framework only addresses temperature increase and extreme heat disasters. Other climate change-intensified extreme weather events, like 2024’s Hurricane Helene that inundated Appalachian Mountain communities would require far more complex scientific assessments. A North Carolina plaintiff, for example, who wanted to sue fossil fuel firms for their role in the disaster would need to prove in court how extreme heat warmed the Gulf of Mexico to record levels, causing Helene to pick up excessive moisture, intensifying the storm and creating 1000-year floods. Drawing such connections may become possible in the future. Image courtesy of NCDOTcommunications.
I’ll let my editor, Glenn Scherer, in his summarizing bullet points, describe this story of mine:
In recent decades a growing number of lawsuits have been launched by states, cities and other government entities to hold fossil fuel companies financially liable for the climate harm caused by the greenhouse gas emissions their products produce.
But those efforts often come up against challenging legal arguments made by the companies saying that their actions and emissions cannot be scientifically linked to specific climate change-driven extreme weather events.
Now, fast-advancing attribution science is offering answers to those legal arguments. A new study — published in Nature — has created a framework that connects the emissions over time of the world’s largest fossil fuel companies — BP, ExxonMobil, Chevron, Saudi Aramco and Gazprom — to rising temperatures and specific heat-related climate disasters.
Researchers say that, in time, this framework for assigning attribution and financial damages could be extended to specific fossil fuel companies and a range of climate change-intensified extreme events such as hurricanes, flooding, sea-level rise and wildfires. The framework has yet to be tested in court.
Pope Francis was very much a man of the people while traveling to 68 countries during his pontificate. At least once a week while in Rome, he would cruise around St. Peters Square to greet pilgrims and tourists who had come to visit Vatican City, like this encounter in June 2016.

This story is one I was both sad and eager to write. Sad because of the death of Pope Francis at 88, one of the most extraordinary leaders of the global Catholic Church in generations; eager because Francis in a very tangible way brought me to Mongabay; I’ve been covering for the past decade his ceaseless crusade to implore people of all faiths to protect “God’s creation” and fight climate change we are all making worse.
In 2015, I had recently pivoted from local news reporting to international environmental reporting after a nudge and plenty of inspiration from my friend and colleague Miles Silman, a leading tropical ecologist at Wake Forest University, where we both teach. That summer, while I was teaching a summer session for Wake students in Rome, I was contacted by Jon Sawyer, founder and then CEO of the Pulitzer Center, with an offer to travel to Latin America — home ethnic home of Pope Francis — and evaluate whether people there (overwhelmingly Catholic) were apt to listen to and follow his teachings in Laudato Si, a Catholic teaching document of the highest order, and the first focused exclusively on climate change, environmental degradation and humankind’s heavy hand in destroying the planet. The encyclical made global headlines, inspired environmental activism and incited a growing number of enemies. It’s spirit is woven throughout the preamble of the historic Paris Agreement on climate change of 2015.
I said yes to Jon Sawyer’s offer and chose to report from all over Peru for three weeks. Enrique Ortiz, my friend and Peruvian biologist, agreed to be my fixer, and my oldest daughter Emilia came along for two of those weeks as my photographer. The stories I produced enabled me to make a real pitch to Mongabay founder and editor-in-chief Rhett Butler. He agreed to take my stores, assigned Glenn Scherer to be my editor, and Glenn and I have been working together ever since.
When the pope died on April 21, 2025, at the Vatican the day after Easter, Glenn and I spoke soon after. Given the many stories I’ve written on Francis and the intersection between faith and climate action over the years, Glenn urged me to put together a reflection on Francis’ environmental legacy. I agreed, leaning heavily on the pope’s own words and exhortations among three pioneering documents since 2015.
Except: This singular leadership will surely be a lasting part of his legacy, as his words continue spreading like soft ripples across the Earth he loved. “There is a mystical meaning to be found in a leaf, in a mountain trail, in a dewdrop, in a poor person’s face,” Francis wrote. “The world sings of an infinite Love: how can we fail to care for it?”
In 2015’s Laudato Si’, Pope Francis wrote about our responsibility to each other and to the planet, with much of his inspirational language later woven into the preamble of the historic 2015 Paris climate agreement. In 2023’s Laudate Deum, he urged world leaders to take decisive action on climate change, before the planet reaches “the point of no return.” Image by Justin Catanoso for Mongabay.
Krystal Martin (center) has for months lobbied local and state officials about what she and her neighbors believe are health hazards posed by pollution from one of the largest wood-pellet mills in the world, owned by Drax and located near the center of Gloster, Mississippi. She organized neighbors on April 8 to fill a hearing room in the capital of Jackson to argue against a permit for Drax to legally emit more toxic pollution during its manufacturing process.

It is a rare thing when a small, poor Black community stands up successfully to a corporate giant like Drax, one of the world’s largest makers of wood pellets for industrial-scale burning for energy. But that’s what happened in Mississippi in April 2025, as this story of mine illustrates.
I learned about this meeting in Jackson, the capital of Mississippi, while I was in Washington in late March to speaks at a forum on wood pellets for energy sponsored by the Rachel Carson Council. Krystal Martin discussed the organizing efforts her group, in conjunction with several environmental groups, were pursuing to keep Drax from increasing the amount of toxic emissions it was already putting into the air over Gloster, Miss., where Drax has its largest facility. The community argument prevailed over the business argument put forth by Drax. That just doesn’t happen very often, especially in environmental justice communities like Gloster.
This is one of those examples where a public health and quality of life argument from a local community may just have more impact in pushing back against the growth of the wood pellet industry than the years of scientific arguments that have largely failed to persuade policymakers in the European Union and United Kingdom to shift away from their reliance of forest biomass for energy as the primary way to phase out coal.
In 2020, two years after the Vattenfall wood pellet energy plant was proposed, forest advocates organized a youth protest outside Vattenfall headquarters as part of the National Children’s Climate March. Image courtesy of the Clean Air Committee in the Netherlands.
As this stories describes, forest advocates were able to take significant credit in The Netherlands when one of its largest energy providers canceled plans in February 2025 to build the largest wood-pellet-only power plant just outside Amsterdam. It took six years and a circuitous route through the Dutch court system, but on a rare occasion, the environmental argument that burning forest biomass is not the climate-friendly solution it is touted to be until won out.
While the Dutch, like the South Koreans, appear to be inching away from industrial-scale forest biomass energy, neither is close to giving up entirely on wood burning, or subsidizing the burning, as they both try to meet 2030 legal deadlines to phase out all coal burning.
In fact, the elusive promises of BECCS — Bioenergy with Carbon Capture and Storage — is now being touted as the reason to continue burning wood pellets because, it is theorized, that emissions can be easily trapped and permanently buried underground.
There is a significant flaw in that plan in that the scientific consensus illustrates that BECCS technology is years, if not decades, away from effective implementation.
“The irony is that my country (The Netherlands) and the EU have called burning biomass carbon neutral, right?” Dutch forest advocate Fenna Swart told me. “Now the claim with BECCS is that the air will be even cleaner. But in our view, it’s just another flawed policy to allow business as usual.”

This story here, my latest on the issue of global forest biomass for energy, sends a bit of a mixed message. Projected supply and demand for wood pellets appears to be rising dramatically through 2030, with more wood coming from tropical forests than every before.
On the other hand, there appear to be a few cracks forming in the long-term viability of an industry that has been on a steady, upward trajectory for 15 years or more — save for Enviva’s self-inflicted business wounds that led to its 2024 bankruptcy. Subsidies are being inched back on South Korea and Japan. Drax is still getting a ton of British subsidies for five more years, but far less than the previous 10. Germany’s second-largest city, Hamburg, nixed a conversion of a coal-burning plant to wood, admitting that it was not a climate friendly move. And a highly regarded investment think tank is raising a bright red flag to investors to think twice before investing in wood-pellet manufacturing stocks.
A source and forest advocate in South Korea went as far as to tell me he believes we are beginning to see that beginning of a paradigm shift regarding forest biomass for energy. The scientific arguments and journalistic reporting, including my own, that challenge industry line that it a climate-friendly alternative to coal, grow stronger every year. Is the tide really turning?
Meanwhile, in the near-term, the industry continues to grow, and native forests across the US Southeast, British Columbia, Eastern Europe and Southeast Asia, will continue to be diminished and degraded, many replaced by tree farms, to feed immediate demand.

Indigenous Leaders and local communiites had plenty to cheer about at the outcomes of COP16 CBD in both Cali, Colombia and Rome, Italy. Image by IISD/ENB | Mike Muzurakis..
Outcomes of international environmental meetings are always hailed as grand achievements but almost always produce unrealistic or unreachable results, most involving the promises of raising billions in annual funding that always falls far short of stated goals.
But at the 16th United Nations Convention on Biological Diversity, started in Cali, Colombia, in October 2024 and finished in Rome, Italy, in February 2025, Indigenous Peoples and Local Communities (IPLCs), actually had new and tangible breakthrough achievements to celebrate, as this story of mine illustrates.
Highlights include the kind of official recognition from now on that enables IPLC leaders to be active, at-the-table negotiators on issues that involve them for the first time, and a new funding mechanism — the Cali Fund — that does not depend on donations but rather fees from global corporations who use nature-based genetic materials for commercial products. If companies contribute, as they are urged to do by COP16 final language, it could mean hundreds of millions annually for conservation projects identified specially by IPLCs.
“COP16 has been a great success and is historic for us,” Viviana Figueroa, a global technical coordinator with the International Indigenous Forum on Biodiversity, told me from Rome.

I spent eight days in Cali, Colombia in October 2024 covering my first UN Convention on Biological Diversity summit. I left before the final day, but as this story illustrates, it ended up not being the final day.
Delegates left the hardest work for last — specific strategies by which nations and non-government actors could reach $200 billion annually in finance to protect nature and stave off deforestation and species extinctions. They ran out of time. Delegates fled to catch flights at the Cali airport. And the COP16 president, Susana Muhamad, was forced to close the biennial meeting prematurely.
Delegates did agree to meet for three days in February in Rome (Feb. 25-27) to complete their work. And they did. As best they can. My story overviews what they accomplished and the difficulty they will have in reaching their ambitious and critically important goal. Alas, I reported from home in North Carolina, not from Rome, my favorite city in the world.

It’s always a pleasure to join the Mongabay podcast with my colleague Mike DiGirolamo, who is now based in Australia. He was interested in discussing, in part with me, the most significant story I reported from Colombia in October 2024 from the United Nations biodiversity summit, or COP16.
Here’s what Mike writes: The Brazilian government in 2023 announced a novel funding mechanism to incentivize forest preservation: the Tropical Forest Forever Facility (TFFF). In an episode of Mongabay’s weekly podcast Newscast, host Mike DiGirolamo explored what experts think about the TFFF, what it can do, and what it can’t.
Mongabay contributor Justin Catanoso, who has written previously about the new fund, also known as the Tropical Forest Finance Facility, told DiGirolamo a key component that makes it different is that the money is neither a loan nor a donation. Instead, it’s an investment fund, where the “investors get paid back first, and the money that is generated by the investments above what the investors get is what will be given to the tropical countries,” Catanoso said.
Charlotte Streck, co-founder of advisory firm Climate Focus, also joined the podcast. She told Mike that the TFFF “has great potential because it is put forward and supported by tropical rainforest countries.”

It’s not often that a news organization reflects on its coverage over recent years to evaluate the impact that that coverage has had on a region, a group of people, and in this case, an industry. But in making the case to our global readers and funders, Mongabay recaps important stories or series of stories to let people know that independent environmental journalism can and does make a difference in the world.
In this story penned by Mongabay editors, they recap my coverage of the forest biomass industry over the last several years and explain the impact it has and continues to have. The story rightfully focuses on one of the most prominent and impactful stories of my long career in journalism — the one and only whistleblower to ever come forward from inside the forest biomass industry (from Enviva, once the world’s largest producer of wood pellets for industrial-scale energy) and his candid, verifiable attack on his company’s climate- and environmentally friendly claims of the product it produces. That story, which has a complementary video, was published in December 2022.
Here’s an excerpt from Mongabay’s story of my reporting:
“This case demonstrates how independent journalism can expose greenwashing, inspire tangible action, inform public policy, and create ripple effects across sectors. Mongabay’s reporting uncovered the troubling realities of the biomass energy industry, and it empowered governments, financial institutions, and legal advocates to take decisive action in the pursuit of accountability and environmental justice.”
In Spring semester 2020, I was asked by Dan Cohen and Greg Pool, both leaders of the Center for Entrepreneurship at Wake Forest University, if I would consider hosting a podcast in which I interview guests to campus about the companies they had founded or are in the process of building.
I said yes. And the result has been The innovator, hosted on Spotify and linked here. It is similar in focus to the popular podcast How I Built This, hosted by NPR’s Guy Raz. Like Raz, I engage a wide rage of entrepreneurs in their origin stories – both personally and business wise. Here’s why I didn’t hesitate to take on this new challenge.
Before I starting covering environmental issues in 2013 first as a freelancers and by 2015 almost exclusively for Mongabay, I was the executive editor of the Triad Business Journal from its founding in 1998 until I left for full-time teaching at Wake Forest in 2011.
During those 13 years leading coverage of the Triad economy and writing a weekly column, I learned a great deal about the entrepreneurship — the special leadership qualities, vision and risk tolerance necessary to start something from scratch, often with other people’s money. We covered new-business startups closely and the personalities behind the companies. We covered the investors, too, those willing to underwrite good ideas and risk millions in the process.
Hosting the Innovator was simply a natural extension of a knowledge base I had developed over a long period of time. When you put that together with the 15 years I was on public radio each week with WFDD-88.5 FM, shifting to a long-form podcast format was pretty seamless. Special thanks to Greg Pool for being the producer of The Innovator.
