The coal industry can damage human health in myriad ways via dangerous working conditions and harmful pollution. But the income opportunities offered by the industry can also provide much-needed stability for certain communities, such as those in Appalachia’s coal country.
“Being employed is good for your health, but environmental pollution is bad for your health, and these two things are operating at the same time in some communities,” said Mary Willis, an epidemiologist at Boston University.
The industry, though, is changing. Total coal production in the United States peaked in 2008, and the number of miners has steadily dropped since then.
A new study coauthored by Willis and published in Rural Sociology delves into the effects of this decline on life expectancies across the United States and in Appalachia in particular. The results show that a disappearing coal mining industry has mixed effects on health, highlighting the importance of a “just transition”—a shift away from coal mining and toward clean energy that also prioritizes decent work opportunities for those left without a job.
“How do we balance these two conflicting priorities?” Willis said.
Coal production and consumption are linked to many human health harms, including heart disease, asthma, lung cancer, mental illness, and more. But how those health impacts intersect with the broader economic effects of mining has not been well studied.
In the new study, the research team analyzed the effects of the declining industry through the lens of the social determinants of health, or how social structures influence health outcomes.
To study these effects, the team compared coal mining data from the U.S. Energy Information Administration to life expectancy data from the Institute for Health Metrics and Evaluation at the University of Washington from 2012 to 2019. Life expectancy is a metric that can be responsive to subtle changes in the environment, Willis explained. For example, the decommissioning of a coal-fired power plant a few miles away from a community may not affect residents’ day-to-day life but probably affects the scale of life expectancy across the population.
In coal-producing counties across the United States, the average life expectancy was 1.6 years lower than that in non-coal-producing counties. But the declining coal industry had more nuanced impacts on health in Appalachian communities, the researchers found. As coal production fell and miner labor hours decreased, life expectancy increased. But as the number of jobs available decreased, life expectancy decreased, too.
The findings suggest that the employment and associated economic impacts of a waning coal industry harm health. Previous studies documented similar increases in mortality in other regions where the fossil fuel industry has declined. Such research has indicated that these increased mortality rates may be partially driven by “deaths of despair” from drug and alcohol use and suicide related to economic distress. The association of these factors with mortality rates in coal country, the authors suggest, may be an area for future study.
Understanding that coal mining is associated with some positive economic and health effects is “an important perspective for understanding the sector as a whole,” said Lucas Henneman, an environmental engineer at George Mason University who was not involved in the new study. “It’s a really interesting piece of work.”
“This is just a really complex story that hasn’t been told yet—putting health into the context of these just energy transitions,” Willis said.
The complex reality of the coal industry extends beyond Appalachia. Most of the pollution related to the coal industry consists of toxins released when coal is burned, meaning those who bear the brunt of coal’s health impacts may not be located where coal is mined, Henneman said.
In fact, a 2023 study by Henneman and others found that before 2009, a quarter of all air pollution–related deaths of people on Medicare were attributable to coal burning. From 2013 to 2020, that number dropped to 7%, alongside a drop in coal consumption. A complete picture of how the coal industry affects health should also consider how pollution travels beyond coal country—where it’s burned, how it’s transported in the air, and who ultimately breathes it in, he said.
“The question is how to provide [jobs] in a way that provides the same level of stability, same kind of income benefits, and isn’t too much of a shock to [communities’] way of life or sense of identity.”
The economic activity of a mine, through direct employment as well as businesses reliant on the mine and miners, “chases away other opportunities,” making the mine the economic backbone of the area, said Jonathan Buonocore, an environmental health scientist at Boston University and a coauthor of the new study. The concept of a just transition aims to ensure that employment opportunities in the wake of the coal industry’s decline reach these communities.
“The question is how to provide [jobs] in a way that provides the same level of stability, same kind of income benefits, and isn’t too much of a shock to [communities’] way of life or sense of identity,” Buonocore said.

Wildfires can increase flooding risks in and downstream of burned areas by removing vegetation and disturbing hydrologic processes. As the climate changes, the severity of both wildfires and heavy rainfall events is increasing, meaning flooding is likely to become more severe in the near future. Better understanding how, and by how much, wildfires change flood risk is important for disaster and infrastructure planning for communities around the country.
Canham and Lane used streamflow data from the U.S. Geological Survey’s National Water Information System and precipitation data from the NOAA Analysis of Record for Calibration product to identify storms and quantify their effects across seven burned watersheds in the western United States.
To make the most of the limited data on flooding in the years following wildfires, the researchers created a paired-storms framework: They identified postfire peak flows (PFPFs), defined as the five highest peak flows within 3 years of a wildfire across seven watersheds. Then, for each precipitation event causing a PFPF, they looked for storms with similar characteristics (or paired storms) that occurred before the wildfire. Storm characteristics used for pairing included the season in which the storm occurred, recent precipitation, and precipitation depth, duration, and peak intensity.
The researchers found significantly elevated peak flows after wildfires in many cases, underlining the risks to communities following wildfires and validating their approach for use elsewhere.
Altogether, the authors found 26 PFPF events, including 20 with paired storms occurring before wildfires. For 75% of the postfire storms, their peak flows were 2 or more times greater than prefire peak flows. PFPFs were most likely to happen in the first year after a wildfire and typically occurred following storms that were centered upstream of the watershed centroid, were uniform in shape, and fully covered the watershed and burned area, the authors reported. They also found some evidence that the first storm in the year immediately following a fire has a higher-than-expected chance of producing a PFPF.
Future work could look more deeply at the characteristics of storms occurring over burned areas, such as storm direction and watershed recovery, and could apply the automated methods to more burned watersheds and storm events to enhance the robustness of the work, the authors say.

The albedo change of marine clouds is achieved by targeted additions of aerosols, and in particular, sea salt. To assess the viability of Marine Cloud Brightening (MCB) requires a fundamental understanding of the impact of aerosols on cloud evolution and properties, and on the cloud environment.
Doherty et al. [2026] propose a framework for studying MCB across scales. This includes small- to large-scale studies aimed at systematically characterizing the life-cycle of aerosols and the diurnal cycle of cloud processes, how these change with the magnitude, duration and type of aerosol applied, and monitoring potential harmful direct or indirect consequences of aerosol injection, such as regional changes in temperature or precipitation.

Out of 52 climate targets needed to reach net zero by 2050, only six are on track or have been met. The other 46 are behind, failing, or marked as Code Red. This is according to the Speed & Scale tracker, a detailed public scorecard that measures if the global economy is cutting emissions fast enough.
The tracker is part of an initiative started in 2021 by investor John Doerr, known for backing Google and Amazon early on. He used Silicon Valley’s Objectives and Key Results method to tackle the climate crisis. The 2026 edition comes with a new letter from Doerr called “Let’s Build, Friends, Build,” a call to focus on the need to build solutions. As he puts it, pledges alone won’t cool the planet—real progress comes from cutting emissions.
Speed & Scale breaks down decarbonization into 10 main goals, such as electrifying transportation and investing in clean energy. Each goal has measurable key results with targets for 2035 and 2050. Progress is rated on a five-level scale, from Achieved to Code Red. Code Red is the worst rating and is given to areas with over 3 gigatons of yearly emissions and little or no progress.
The 2026 update now uses Climate TRACE, a satellite and AI system, instead of UN country reports to measure emissions. This change raised the baseline from 59 gigatons in 2019 to 74 gigatons in 2024. The increase is not due to a sudden jump in emissions, but because TRACE finds fossil-fuel activity that country reports often miss. Atmospheric CO₂ is now at 429 parts per million, which is about 53 percent higher than before the industrial era.
The key results that are on track have one thing in common: clean technology has become the cheaper choice. Electric vehicles show this best. There were about one million EVs on the road ten years ago, but now there are over 50 million. EVs make up more than 20 percent of new car sales worldwide and over half in China. In the first nine months of 2025, enough solar and wind power was built to stop the growth of fossil fuels in electricity. According to BloombergNEF, solar costs have fallen by 84 percent since 2010.
There are now three million more clean-energy jobs than fossil-fuel jobs worldwide, according tothe International Energy Agency. For the 249 Fortune Global 500 companies that report their direct emissions (Scope 1 and 2), those emissions have dropped by 23 percent since 2019. However, Scope 3 emissions, which include supply chain and product use, make up about 95 percent of their total and are not decreasing as quickly.
Methane emissions from oil and gas operations are still going up, even though the IEA says 75 percent could be cut using current technology, often at a net savings. Methane is about 80 times more powerful than CO₂ over 20 years, making it the most cost-effective way to cut emissions, yet progress is going in the wrong direction.
BuildingMost building heating and cooling still relies on fossil fuels, even as a million new buildings are added each month. Heavy industry is also behind: there are no commercial-scale zero-carbon steel plants and only one net-zero cement facility in the world. The tracker says we need 700 steel and 300 cement plants by 2035. Industrial agriculture and livestock are also rated Code Red. Carbon removal is far behind too—by 2025, just over one million metric tons have been removed, according to CDR.fyi, but the plan calls for 14 billion tons per year by 2050.
Where Each Objective Stands
| Goal | On Track | Not On Track |
| Electrify Transportation | Cars | Planes and ships failing |
| Decarbonize the Grid | Solar & wind | Methane and buildings Code Red |
| Fix Food | None on track | Farming and meat Code Red |
| Protect Nature | Gradual | 18 soccer fields of tropical forest lost per minute in 2024 |
| Clean Up Industry | Pilots only | Steel, cement, plastics all Code Red or failing |
| Remove Carbon | Afforestation | Scale roughly 10,000x short |
| Politics & Policy | EU NDC aligned | U.S. has no national commitment; carbon pricing failing |
| Movements → Action | Clean-energy jobs achieved | Voter salience, air quality, education lagging |
| Innovate | Electricity and EV costs | Industrial heat, steel, cement, hydrogen all failing |
| Invest | None on track | Fossil-fuel subsidies still exceed clean-energy incentives |
In his new letter, Doerr says the climate challenge is now shaped by three main forces: rising demand for electricity, the global politics of clean-tech manufacturing, and falling costs thanks to market forces. He writes, “We cannot cut fossil fuels without building the alternative.” The updated tracker shows this change. While the 2021 plan focused on percentage reductions, the 2026 version spells out what needs to be built: 600 million EVs, 700 zero-carbon steel mills, and 30,000 TWh of solar and wind power.
Doerr also shares the toughest update: Speed & Scale now says keeping global warming to 1.5°C is no longer possible. Five more years of rising emissions have used up the remaining carbon budget. The new goal is to stay below 2°C, with the U.S., EU, and China aiming for net zero by 2050.
The post The World Has a Decarbonization Scoreboard. Here’s What It Says. appeared first on Earth911.
The bag your potato chips come in is seven layers deep. Metalized polyester, a plastic coated with a thin layer of metal, keeps out light. Polyethylene, a common plastic, holds the seal. A printed film provides the label. An oxygen barrier, a layer that blocks oxygen, helps prevent spoilage. There’s another sealant (a layer that helps bond the package), another structural layer for strength, and a food-contact inner skin that directly touches the chips. Each of those layers solves a problem for the manufacturer: preserving freshness, supporting branding, and extending shelf life. Together, these layers are a package no U.S. recycling system can recover for future use.
To put the potato chip bag problem in context, consider American packaging waste as a whole. Americans generated roughly 82.2 million tons of containers and packaging in 2018, about 28 percent of all municipal solid waste, according to the EPA’s most recent national accounting. Plastic packaging contributed more than 14.5 million tons of the total. Those figures are now seven years old. EPA has not issued an updated Facts and Figures report since, even as e-commerce shipments and single-serve formats keep multiplying the number of small, lightweight, hard-to-recycle packages moving through American homes.
The freshest picture comes from California, which is now doing what the federal government has stopped doing. CalRecycle’s SB 54 Material Characterization Study, conducted by Cascadia Consulting Group at 16 landfills in early 2025, found that about 8.5 million tons of single-use packaging and foodware were buried in California landfills in 2024, roughly 21 percent of everything the state landfilled that year. Plastic accounted for about 3.1 million tons of that covered material. Flexible and film plastics — the category that includes chip bags — turned up across all sampling sectors, from single-family curbside collection to commercial routes and self-haul loads. One state, one year, and the composite pouch is everywhere the waste auditors looked.
While composite pouches present a recycling challenge, some rigid plastics fare better. The rigid side of the plastic waste stream — PET water bottles, HDPE milk jugs, some polypropylene tubs — has a functioning recovery system. NAPCOR’s 2024 PET Recycling Report put the U.S. PET bottle collection rate at 30.2 percent; over 70 percent of bottles that reach a curbside bin actually are sorted, baled, and reprocessed into new material.
The situation shifts again when looking at flexible packaging specifically. Flexible bags, pouches, wrappers, and refill sacks that have quietly taken over the grocery aisle are a different story. The U.S. Plastics Pact’s most recent impact report reported a combined U.S. plastic packaging recycling rate of 13.3 percent. Flexibles within that number are a rounding error. Most estimates put flexible-packaging recycling in the United States below 2 percent.
Greenpeace’s 2022 assessment concluded that no type of U.S. plastic packaging meets the Ellen MacArthur Foundation’s definition of ‘recyclable,’ a 30 percent recycling rate across a region of 400 million people.
Three things make flexible plastic packaging structurally hard to recycle:
Composite film is what industry insiders call a “residual cost material”—meaning the combined cost of collecting, transporting, and processing it exceeds what any buyer will pay for the recovered commodity. The private market will not recycle it.
For a decade, the polite answer to “what do I do with this bag?” has been: take it to the front of your grocery store. The bins marked for plastic bags and film — operated by the Wrap Recycling Action Program (WRAP) and branded by retailers including Walmart, Kroger, and Target — accept clean polyethylene films: grocery bags, bread bags, dry-cleaning bags, produce bags, and some case-pack overwrap, but not chip bags and other packaging made with composites that combine plastics, paper, and metals.
Most of the polyethylene that does get captured at drop-off goes into composite lumber — Trex decking is the dominant end market, which is a form of downcycling rather than a closed-loop system. It’s a better outcome than landfill. It is also not what the word “recyclable” on the package implies.
When mechanical recycling cannot process a feedstock, industry increasingly points to “advanced” or “chemical” recycling, which includes pyrolysis, gasification, and solvent-based depolymerization, as the solution for films and flexibles. The promise: break the polymer down to monomer or fuel-feedstock molecules that can be re-polymerized or combusted.
The promise is technically real, though many critics question its promised results. The scale is not yet. Most operating U.S. pyrolysis facilities produce pyrolysis oil sold as fuel, which, from a climate perspective, is combustion with extra steps. A 2023 NRDC analysis found most “advanced recycling” projects in the U.S. are either producing fuel rather than new plastic or operating at a pilot scale. Facilities designed for polymer-to-polymer chemical recycling, such as Eastman’s Kingsport, Tennessee, plant, and Alterra’s Akron facility, process a small fraction of national flexible-packaging generation.
Twenty-five states have now classified advanced recycling as “manufacturing” rather than waste management, easing permitting requirements and exempting the facilities from solid-waste oversight (regulatory supervision for handling waste). Environmental-justice advocates (groups focused on pollution impacts on vulnerable communities) argue the reclassification moves emissions and solid-residue handling out from under the permitting regime designed to protect fenceline communities (neighborhoods directly next to industrial sites). The argument is not settled.
The meaningful change in the flexible-packaging story over the past eighteen months has not come from new recycling technology. It has come from policy: seven U.S. states now implement Extended Producer Responsibility laws for packaging.
Oregon’s program went operational on July 1, 2025, with the Circular Action Alliance serving as the producer responsibility organization (PRO) that manages the program, supported by roughly $200 million in producer funding for the first year. The state plans to build out 144 PRO-operated recycling collection centers across the state. Colorado, California, Minnesota, Maryland, Washington, and Maine are at various stages behind Oregon, with California’s SB 54 program — the most expansive of the group — scheduled to be fully activated in 2027.
What EPR changes, in plain terms, is that the producer — the brand that chose the seven-layer laminate for branding and shelf life reasons — now pays for the collection and recovery of the package after a consumer uses it. The fees are eco-modulated: simpler, mono-material, more-recyclable packaging pays less; hard-to-recycle multi-layer flexibles pay more. Over time, the fee differential is intended to push producers toward redesigning packaging.
The externalities the household pays for without seeing them, from flexible packaging specifically:
None of these costs appear on the grocery receipt. Yet, you’re paying these fees until EPR programs force producers to do so.
For individuals and households, you can make these choices:
At the community and policy level, you can get involved:

Việt Nam is looking to unlock the vast potential of its nearly 8,000 reservoirs to drive sustainable aquaculture growth, boost rural livelihoods and strengthen the fisheries value chain.
In the contiguous United States, crop irrigation, municipal water supplies, and thermoelectric power generation use more than 224 billion gallons of fresh water every day. Conducting water research or making decisions about water use, until now, often required referencing datasets across various agencies. The U.S. Geological Survey (USGS) National Water Availability Assessment Data Companion (NWDC), announced this week, aims to streamline this process. In part, the tool is designed to help decisionmakers better understand the balance between how high demand and limited supply affect water availability in their communities.
“While the United States has abundant water nationally, regional imbalances between supply and demand may create water challenges affecting millions of Americans,” said lead scientist Shirley Leung in a USGS press release. “What once required significant resources and time can now be done in minutes, giving communities of all sizes the same foundation for water planning.”
The lower 48 states are home to about 80,000 sub-watersheds, from those in the arid southwest to the Great Lakes Basin, where about 84% of North America’s surface fresh water is located. According to the USGS, the NWDC is the first tool that integrates information about water availability in individual watersheds at a national scale.
The tool is designed to complement Water Data for the Nation (WDFN), another USGS product that consolidates observational data from the agency’s thousands of local monitoring stations gathering data on streams, lakes, reservoirs, precipitation, water quality, and groundwater. The new tool uses modeling to fill in spatial and temporal gaps between the observations made at these stations.
Water managers, researchers, agricultural experts, and others can use the NWDC to compare watershed conditions, identify seasonal patterns in water use, or to create data visualizations of statewide water use, for example. Though the tool currently covers only the contiguous United States, it will soon be extended to Alaska, Hawaii, and Puerto Rico, according to the USGS.
David Tarboton, a professor of civil engineering at the Utah Water Research Laboratory, said he was “intrigued” by the new tool, and is interested in examining the data its model produces.
While Tarboton was disappointed that the tool’s most recent available data are from 2020, “having a sort of integrated, wall-to-wall dataset that’s consistently produced is very valuable,” he said. He works, in part, in the areas of hydroinformatics and data sharing, and noted that the modern methods the agency is using to share the data could be useful in developing automated tools.
