07/30/2026 Project Drawdown Is climate change unfolding faster and fiercer than scientists expected?  - Climate change is driving unprecedented extreme weather around the world, from catastrophic floods and prolonged droughts to blistering heat waves and raging wildfires. While these events are unprecedented, they were not unpredicted and largely align with what scientists have been warning about for decades. Climate science tells us that things will get worse as long as humans keep emitting greenhouse gases into the atmosphere. But the science also shows us that a better future is still within reach.

08/07/2026 Smart Cities Dive For local governments, full benefits of ROAD to Housing Act could take years - The bipartisan legislation promises sweeping regulatory reforms and funding incentives designed to increase housing development.  Of the 124 implementation actions detailed in the bill, HUD is responsible for 88, or 71%.L ocal governments can begin assessing what regulatory changes — such as updating zoning, building codes and permitting policies — they will need to enact to take advantage of federal funding once it becomes attainable.

08/09/2026 Cool Green Science Bug Highway: The Hidden Paths Used by Insects - Many important pollinators have home ranges no larger than 400 or 500 meters. Some are even smaller. So, in order for them to survive, they must find something to eat within their home range, the distance they’re willing to stray from their nests. And that means every window box, every garden, every bit of green space could be what some insects need to survive.

08/10/2026 Our World in Data 138 million children are in child labor. What does this actually mean? - Child labor is work that is done by a child and is likely to be harmful. This general principle was first codified in international legal conventions more than a century ago, and a series of them in the 20th century made its scope more precise, linking harms to work that endangers children’s “health, safety, or morals” or work that interferes with their schooling. It spans children working in exploitative and dangerous conditions, as well as children who are counted not because of the conditions they work in, but because they are too young to be working at all, even if that means helping on a family farm for only a few hours a day.

08/05/2026 NASA The Paradox of Lençóis Maranhenses National Park - The coastal dune system in Lençóis Maranhenses National Park in northeastern Brazil is among the most surreal landscapes on Earth: rows of sparkling white quartz dunes, some rising 30 meters (100 feet), soar over a mosaic of blue and green freshwater lagoons.

08/11/2026 My Modern Met Mini Wildlife Portraits Made with Plastic Toys and Other Materials That Threaten Real Animals Today – Look at the pictures and watch the 6-minute video about how they were created.

08/10/2026 Smithsonian Magazine Spinal Deformities in Saber-Toothed Cat Fossils Reveal How the Now-Extinct Felines May Have Spent Their Final Days - Thousands of years ago, sticky tar pits in modern-day Los Angeles, California, became the graveyard for prehistoric felines struggling with deformities and disease. 3,722 vertebrae from at least 849 saber-toothed cats were examined. CT scans revealed a significant number of developmental abnormalities in the feline spines. The team identified 32 vertebrae with arches that hadn’t completely developed, 48 “block” vertebrae where bones had fused together and 226 “transitional” vertebrae that hadn’t formed correctly. Perhaps most notably, three vertebrae from different individuals contained enlarged holes that allowed nerves and blood vessels to thread through them. The holes’ sizes and smooth remodeled surfaces hint that the cats had spinal nerve tumors.

07/24/2026 Project Drawdown Reversing soil degradation 10% could feed 70 million more - Human-caused damage to soils is a limiting factor for food production on agricultural lands. Soil degradation can be slowed or reversed. Reversing degradation by 10% could make it possible to feed 70 million more people while also enhancing soils’ ability to pull greenhouse gases from the atmosphere and reducing pressure to turn forests into farmland.

08/11/2026 NASA Bountiful Roebuck Bay - Roebuck Bay's tidal range can reach a remarkable 9 meters (30 feet). Rising and falling tides repeatedly inundate and expose expansive mudflats, flood broad mangrove forests and salt marshes, and feed branching networks of tidal drainage channels. The bay's dramatic tidal and seasonal changes are striking from above, and they also support a bounty of life on the ground. The mangroves serve as nurseries for crustaceans and fish, and the mudflats teem with dozens of types of invertebrates, including snails, worms, crabs, clams, and cockles. Shells and snails can reach an abundance of 2,500 per square meter. The bay, one of the most important sites for migratory birds in Australia and a key stop on the East Asian-Australasian Flyway, regularly hosts hundreds of thousands of birds, including plovers, godwits, and knots.

08/10/2026 BBC Future We're getting mealtimes wrong - here's the best time to have dinner - Aim to eat at regular times and eat fiber-rich carbohydrates such as whole grains, legumes (beans, peas and lentils) as well as fruit, earlier in the day when the body is better able to process them. In the evening, opt for a lighter meal, ideally one rich in protein….making lunch the largest meal.

Leadership Styles

As I thought about and then accepted the president’s role in my Missouri Master Naturalist chapter, I thought about the leadership styles I’ve learned over the years…and the ones I am applying in my post-career endeavors.

Probably the first, and most natural for me, is lead-by-example. It is the style I am least conscious about….and that I only notice when someone obviously emulates what I am doing…or volunteers to collaborate or help.

Organizational judo is a style I heard about in my career and realized that I could apply without being in ‘management’ and in situations where the structure of the organization was working against a project’s success. This type of leadership involves influencing actions of others not in the regular ‘chain of command’ either through timely prompts or providing key information that will encourage their action to achieve a desirable shared outcome. I have always been very organized and am very aware of what is critical for success both near and long term….and have found that my insights are often important in helping others take the actions required. Most people want their organization to be successful but are not always aware of what it will require of them – and sometimes the organization is not as overt of explaining either.

Servant leadership is easy for me to – it is the type of leadership that focuses on getting what the organization needs for everyone to contribute what is needed….realizing that long term success of an organization is built on the individuals in that organization being successful.

Coaching leadership is the type of leadership I often utilize when there is a problem. It is an overt type of ‘lead-by-example’ – pinpointing an issue and structuring conversation to help an individual or small group get through a difficult situation.

I often apply Situational leadership with students or people I don’t know well – assessing what they need from me to be successful in what we are doing. Sometimes they already know what is needed but sometimes I must provide a lot more information before they can proceed.

Transactional leadership is the type of leadership that is highly directive (i.e. I don’t like telling people exactly how to do things!) and I don’t follow it very often with experienced people…I generally want people to bring their experience to bear on whatever we are doing so we need wiggle room for that to happen.

All of these are styles I have used for years and I find myself slipping into different ones depending on what I think will be most effective in the organizations where I volunteer.

08/01/2026 Science Daily Scientists detect a sharp acceleration in global warming - After removing the effects of El Niño, volcanic eruptions, and solar cycles, researchers found that the planet has warmed at roughly 0.35°C per decade over the past ten years, compared with just under 0.2°C per decade from 1970 to 2015. The acceleration, which becomes visible around 2013 to 2015, appeared across five major global temperature datasets with more than 98% statistical certainty. Whether the acceleration continues will depend heavily on future carbon dioxide emissions from coal, oil, and natural gas.

07/28/2026 BBC Future The devil worm is the deepest-living animal. It's redefining life at its limits - Before the 1980s, most biologists didn't think that life existed more than 30cm (1ft) or so below the ground. The detection of deep-dwelling bacteria – and the 2011 discovery of the devil worm – represented a seismic shift in our understanding of the Earth's depths. The devil worm and its subterranean brethren may well be some of the most enduring kind of life on Earth. Studying the deep biosphere could help us better understand the conditions under which living things first came into existence, and even help inform searches for extraterrestrial life; if there is life on Mars, it's probably lurking under the surface. 

07/30/2026 Smithsonian Magazine A Man Unearthed a Mysterious Metal Object Sticking Straight Up from the Ground. It Turned Out to Be a 2,700-Year-Old Sword - Measuring nearly two feet long, the sword dates to between roughly 900 and 700 B.C.E., according to a statement from the Provincial Office for the Protection of Monuments (PUOZ). At that time, it was likely quite valuable. Experts think that it once featured a handle made from organic materials like wood or bone. The handle hasn’t survived, but the engraved patterns decorating the blade are still visible.

07/27/2026 Clean Technica This New Underground Energy Storage System Supports Wind and Solar Power - Flywheels are marking out space in the somewhat rarified world of long duration energy storage. Going by a benchmark set by the US Department of Energy, that means a capacity of at least 10 hours, though ideally long duration technology can stretch into multiple days and longer.

07/16/2026 Yale Environment 360 In Steel Country, the Fight for Clean Air Faces New Obstacles - A Japanese steel giant has pledged billions in new investment in Pennsylvania’s Monongahela River Valley, raising hopes that it would clean up pollution from its steel mills in the region. But documents show that its plans to ramp up production will worsen local air quality.

07/02/2026 Science Daily Eating less protein could slow aging - The findings suggest that protein guidance may be most effective when it takes both age and activity level into account, rather than applying the same recommendation to everyone.

07/26/2026 Clean Technica Every Day in Every Way, Attribution Science Is Getting Better & Better - The National Academies of Sciences, Engineering, and Medicine are private, nonprofit institutions that provide independent, objective analysis and advice to the nation to solve complex problems and inform public policy decisions related to science, engineering, and medicine. They operate under an 1863 congressional charter to the National Academy of Sciences, signed by President Lincoln. This week, the organization published a report that claims attribution science — which seeks to define the connection between human activity and alterations in the climate — has made great strides forward since the last report a decade ago. That report backs a growing body of scientific knowledge that could help governments hold oil, gas, and coal companies responsible for the damage caused by extreme weather.

7/19/2026 BBC Future Scientists are regrowing human teeth - A visit to the dentist could one day involve regrowing damaged teeth tissue or even an entire tooth, rather than repairing it with synthetic materials or yanking it out – an appealing prospect not only because of its novelty, but also because teeth play a greater role in health and well-being than many may realize.

07/17/2026 Yale Environment 360 Drained Under Soviet Rule, Aral Sea Has Become a Huge Source of Emissions - The Aral Sea sits between Kazakhstan and Uzbekistan and was once the fourth-largest inland body of water on Earth. For the past 60 years, though, humans have bled it nearly dry irrigating cotton crops, leaving behind a salty plain the size of Ireland. Its loss has long been seen as an ecological and humanitarian problem, but new research shows that it has also been a significant driver of climate change. When a lake dries up, stored carbon from organic matter on the floor of the old lake bed is released as the dust blows away.

07/16/2026 Science Daily New “living plastic” self-destructs in just 6 days without leaving microplastics - Researchers have created self-destructing living plastic that uses engineered bacteria to completely break itself down when activated. The material degrades in just six days without creating microplastics, offering a potential new solution for single-use plastic waste. (Note that this research was done in China with funding from Chinese government.)

 

Suburban Savanna – 5

Continuing my series on progress toward transitioning my yard to a suburban savanna…..

This is only my first summer implementing the strategy, but I am already experiencing some areas that are overgrown…with natives. In a larger space, the tangle would simply be allowed to continue but in my third acre suburban savanna, actions are needed on my part very similar to my actions when it comes to invasives!

Virginia creeper is great near my front door, and I can easily keep it controlled there because I see it all the time. In other places (in a corner of a flower bed behind some crape myrtle and boxwood, for example), it tends to be problematic, and it requires me to get back there to hack it out. I have been cutting only what is on the brick but now I will cut more and hopefully eventually reduce it to a once-a-year job.

My strategy with poison ivy was to leave it unless it was in a place I would likely be without gloves. Now I am rethinking that even though the patch is interesting because it has the poison ivy leaf gall too. I’m going to gear up and clean out that bed…maybe plant some cone flowers there!

Last year I had a clump of White Heath Aster near my driveway, and it is there again this year….and there is clump in my backyard too. I am leaving both since they are great for pollinating insects in the fall – but I don’t want more of them in my yard.  If they come up in more places next year, I will mow them!

I am learning to cope with pokeweed. If it comes up in an empty space, I leave it…but I trim it to keep it low and leafy. It has filled in an area under a window where a non-native cedar died, a slope on the side of the house (reducing the area I mow and holding the soil with its deeper roots, and filling in a corner (it is hiding a place I dump grass clippings too!).

Grapevines seem to be everywhere this year. I don’t mind them in some places…but I will keep them out of my trees. It is going to take some vigilance.

The same is true with the black raspberry canes. They have lovely pale green stems and white underside of the leaves. There are thorns too. I want to leave some of the plants since wildlife like the fruit…but I will be cutting them in places I want to be able to easily access!

I like violets for the ground cover in all my shady areas but they hide young redbuds and maples and oaks that will eventually need to be cut. Hackberries are everywhere – growing with the hollies and in other bushes. I am considering leaving them but also realizing that I will eventually need to cut them down since they are not in places where I want a larger tree!

All these native plants that I am considering controlling and this is my first year thinking about my yard as a suburban savanna!

July 2026 - Water

An Edge around the Native Plant Garden

Up until a week ago the native plant garden in my front yard was mulch that had been laid down last fall – originally 6+ inches thick – with plants added last spring. Installing something around the edge to define the space required too much back-straining work for me to do myself. I decided to have stone installed, but the work was not scheduled until October; I was thrilled when the company had a cancellation and fit in the work last week!

The two-person crew dug a trench for the stones and finished it in a few hours. Now I can easily do a quick round with the weed-eater and then mow neatly around the garden. I love its irregular shape.

Yard Work in August

The day was in the 70s rather 90s…a good day for yard work. I had big plans. The latter part of July had been relentlessly hot and/or rainy…so there was a lot to do. And the company that we hired to put some edging around my new native plant bed in the front yard was coming the next week rather than in October (they’d had a cancellation – good for us) which meant I needed to do so clean up of that bed as well.

My first project was to get the Virginia Creeper under control. I don’t like it to get all the way up the brick façade of our house or in the bushes or tangled with the air conditioner compressor/other external ‘boxes.’ It’s going to be a continuing battle but I do like to have enough of it showing now so that when it turns red in the fall, the house will look spectacular!

There is also the bed that has been taken over with poison ivy (with the yellow gall on it). I will wear my protective clothing (including gauntlet gloves) and take it out.

And there is a little bit of weed eating along the fence that needs to be done as well.

Around the edge of the native plant garden there is some encroaching grass which needs to be pulled. Hopefully after the edging is in it will be easier to keep it all under control.

On the way to the back yard the pokeweed has turned into clumps (I had cut them to keep them short). They are deep rooted so good for the slope. The corner of the backyard also had a nice clump. I cut the tallest one to keep it mostly below the fence level.

There was a pokeweed that almost hid the American spikenard when viewed from the  yard (although not from my office window). I cut the poke weed even though stepping into the sea of violets left a hole. Maybe the violets quickly

The pathway I take from my office door to the hummingbird feeder is mostly rocks but the violets are taking off there too. I try to avoid stepping on them. Closer to the feeder (which is suction-cupped to one of my office windows) there is a sad crepe myrtle, thorny black raspberry canes, and grapevine that makes getting to the feeder hazardous in less that yard work garb. I cut back everything but the hosta!

The day turned misty and my back started hurting faster than I expected – before I got everything done. But I made good progress and will be out every day it isn’t raining until I catch up. So much to do….and I need to plan to do it in 30-minute chunks to keep my back happy.

07/29/2026 NASA Sizing Up the Sargassum Belt - Sargassum, a type of brown floating algae, has shifted its range in recent decades, thinning out in the North Atlantic’s Sargasso Sea while proliferating in the tropical Atlantic. That trend, underway since 2011, continued in 2026 as the algae, commonly known as a type of seaweed, reached its annual peak in June across a stretch of ocean known as the Great Atlantic Sargassum Belt. The belt’s Sargassum abundance in June 2026 made it the second-highest Sargassum year in the satellite record, slightly behind 2025, according to scientists at the University of South Florida (USF) College of Marine Science. Regionally, the Caribbean Sea and the Gulf of America (Gulf of Mexico) both hit record highs, according to USF’s June 2026 Sargassum outlook. The western and eastern Caribbean saw 3.6 and 9 million metric tons, respectively, while the Gulf saw 5 million metric tons—nearly double its previous record, also set in 2025. 

07/29/2026 Smithsonian Magazine A Metal Detectorist Discovered Tiny Tiles in a Farmer’s Field - John Hill was surveying a farmer’s field in southwestern England when his metal detector identified a Roman-era coin hidden beneath the soil. Now, almost two decades later, archaeologists have returned to the site and excavated the ruins of an ancient villa—complete with a lavish mosaic floor. Stretching across roughly 130 square feet, the mosaic is located near Halberton, Devon. Experts think it dates to the fourth century C.E. The thousands of colorful tiles, each measuring less than half an inch, form a flower with eight petals. This design is bordered by a guilloche pattern, featuring two bands woven together.

07/28/2026 Science Daily 4 in 5 toddler foods are ultra-processed - A grocery-store audit found that many foods marketed for toddlers may be far less healthy than parents expect. Of nearly 2,800 products examined in Texas, 81% were ultra-processed, and almost half failed at least one World Health Organization nutrient standard, often because they contained too much sugar, sodium, fat, or too many calories.

07/29/2026 Planetizen BLM could allow oil leases near sacred New Mexico Indigenous sites - The Bureau of Land Management is considering several options for opening up oil and mineral leases near Chaco Culture National Historical Park, a massive complex of Native American ruins and a sacred site in New Mexico. In 2023, the agency withdrew roughly 336,000 acres surrounding the area from leasing for 20 years, explains Marni Rose McFall in Newsweek. Now, the agency could keep the protections in place, reduce the protected area to a 5-mile (instead of 10-mile) buffer, or remove the protections altogether. 

07/29/2026 NPR The Trump administration's move to end subsidies for Medicare drug plans could cost consumers - Project 2025 was pretty blunt about wanting to push more people into Medicare Advantage…One way to really accelerate that is to make it very expensive to stay in traditional Medicare.

07/29/2026 The Conversation Ten simple and proven ways to reduce your exposure to pollutants in your home - Reducing environmental exposures does not require major lifestyle changes. Small, everyday habits can help create a healthier home environment. For example: Avoid synthetic fragrances and Cut down on Plastics.

07/28/2026 Archaeology Magazine New Thoughts on Wall Paintings in Japan’s Kyushu Tombs - Dated to the sixth and seventh century A.D., the tombs are horizontal stone chambers that could be reopened and were reused for generations. They were decorated with colorful images of spiral circles, horses, boats, and stick-like people. These stick figures were often depicted without faces and shown as smaller than other objects in the paintings. A new study suggests that the images are not portraits of the dead, but anonymous figures who symbolize the journey undertaken by any dead person.

07/28/2026 Yale Environment 260 In Germany, Wind and Solar Overtake Fossil Power - Together, wind and solar generated 44 percent of Germany’s electricity, while fossil fuels generated roughly 43 percent. Germany shut down its last remaining nuclear power plants in 2023. It is aiming to wean off of coal power by 2038, though experts say it will likely achieve that goal much sooner. By 2045, its target date for net zero emissions, Germany plans to convert any remaining gas-fired power plants to green hydrogen.

07/28/2026 BBC Future The spotted lanternfly is ravaging the eastern US. Pet dogs are coming to the rescue - Frequently found plastered across windscreens along the US's Atlantic coast, spotted lanternflies are an invasive pest and a multimillion-dollar disaster for the US's wine industry. A citizen-science program is training pet dogs on demonstration plots like this to find the eggs before they hatch so they can be destroyed. It's revealing the surprising power of pet dogs' noses, with even unconventional sniffer-dog breeds like the humble pug able to play their part.

07/26/2026 Clean Technica Renewables Provide More Than 30% of US Electricity - New data just released by the U.S. Energy Information Administration (EIA), and reviewed by the SUN DAY Campaign, reveal growth of more than 10% in electrical generation by renewable energy sources in the first five months of 2026. Moreover, solar, wind, and battery storage are projected to add about 83.0 gigawatts (GW) of new generating capacity in the U.S. by May 31, 2027 while total fossil fuel and nuclear power capacity will fall by almost 4.7-GW. By comparison, the electrical output of the nation’s nuclear power and natural gas plants experienced much slower growth — just 1.3% and 2.5% respectively. Electricity produced by U.S. coal facilities fell by 10.9%. The combination of just wind and solar, including small-scale solar, provided over 22.2% of domestic electrical production.

07/21/2026 BBC Future A stranding in Ireland sheds new light on the long, slow, ice-cold life of a deep-sea shark – Some species factoids: The Greenland shark, the longest living vertebrate on the planet, can live for around 400 years; Greenland sharks are among the world's biggest sharks, measuring up to 5m (16ft); Greenland sharks are slow-swimming, solitary scavengers and predators. The post documents the study of a Greenland shark carcass that washed up on an Ireland beach in April.

07/21/2026 Yale Environment 360 Long Presumed Dead, a Thriving Coral Reef Is Discovered in West Africa – A paragraph in a 1960s report…and then no investigation again until recently. Researchers have classified the site as a mesophotic coral ecosystem (MCE). Such systems are light-dependent communities existing at the lower limits of reef-building corals. At more than 175 feet below the surface, the coral garden they discovered appears patchily scattered on a rocky substrate.

07/20/2026 Cool Green Science The Bird That Needs Fire: What Bachman’s Sparrow Can Teach Us About Restoration - Long before most people spot one, a Bachman’s Sparrow announces itself from a patch of native grasses, delivering one of the first songs of the season. Small and easily overlooked, it has become one of the most important indicators of whether longleaf pine forest ecosystems are functioning as they should.

07/17/2026 Science Daily Tiny plastics in drinking water may be making dangerous bacteria stronger - New research suggests nanoplastics can actually help harmful bacteria survive by strengthening the slimy biofilms they form inside water systems. These tougher biofilms become more resistant to disinfectants, making them harder to remove and potentially increasing public health risks.

07/15/2026 My Modern Met Tennessee Introduces Anti-AI Seal Supporting Photographers Taking Real Photos of the State - Tennessee tourism has been booming, breaking new records in recent years for the Volunteer State. In 2024, they brought in 147 million visitors and $31.7 billion. This was the fourth consecutive year to break the record in tourist spending, which has surged 36.6% since 2018, more than double the national average. It is important to the state that “what you see is what you get.”

07/23/2026 Science Daily Goodbye, cavities? New gel could regrow tooth enamel - Inspired by the proteins that guide enamel formation in infancy, the gel fills microscopic cracks and draws calcium and phosphate from saliva to grow a new mineral layer that closely matches healthy enamel. After the gel is placed on a tooth, it forms a thin but durable coating that penetrates the tooth's surface and fills small cracks, pores, and other damaged areas. This coating then acts as a framework for rebuilding the mineral structure of enamel. When applied to exposed dentine, the gel can grow an enamel like mineral layer over the surface. This could help reduce tooth sensitivity while also creating a stronger surface for dental restorations to bond to.

07/23/2026 The Prairie Ecologist Those bugs are eating my flowers! What do I do? - If a species is reducing the resilience of a site - mitigate that. Stepping back to put that scene in context with the broader area usually helps answer the question about whether or what to do anything about it. After all, one of the benefits of facilitating ecological resilience is that it gives prairies the ability to adapt and absorb impacts, including Japanese beetles shredding some plants here and there.

07/13/2026 Science Daily Why are healthy young non-smokers developing lung cancer? - Younger Americans under age 50 who have never smoked and consume more of fruits and vegetable than average may face a higher risk of developing lung cancer. Commercially grown (non-organic) fruits, vegetables, and whole grains generally contain higher levels of pesticide residues than dairy products, meat, and many processed foods. There is also previous research showing that agricultural workers with long term pesticide exposure experience higher rates of lung cancer. The next phase of the research will involve measuring pesticide levels directly in patients' blood or urine samples. That work could help determine whether certain pesticides are more strongly associated with lung cancer risk than others.

07/08/26 Archaeology Magazine Scythian DNA Study Examines Elite Family Ties - The remains of 38 of the Scythians were recovered from kurgans that also contained elite weapons and gold artifacts, while the other 47 were recovered from smaller kurgans that lacked gold grave goods. The elite Scythians were 11 times more likely to be related to each other than to the other Scythians. Nearly half of the elite individuals in our dataset were female, indicating that women held high social status within Iron Age Scythian society.

07/08/2026 Smithsonian Magazine Sperm Whales Living in the Eastern Mediterranean Sea Seem to Have Developed a Distinct Dialect from Those in the West - From Southern drawls to Irish brogues, humans can sound very different while speaking the same language. It turns out that some whales might have similar regional variations in their vocalizations, too. Sperm whales living in different parts of the Mediterranean Sea appear to have their own distinct dialects. Scientists think that about 20,000 years ago, a group of intrepid sperm whales swam into the Strait of Gibraltar and entered the Mediterranean Sea, where they’ve remained ever since. The individuals living in the Mediterranean rarely leave the sea—and other sperm whales don’t often enter the area—so they’re considered a genetically distinct subpopulation.

07/07/2026 Clean Technica New York Now at 8 Gigawatts of Distributed Solar Power - New York has just reached 8 gigawatts (GW) of installed solar power capacity in the “distributed” solar market — rooftops and small-scale installations. The state has a target of reaching 10 GW by 2030, and this new milestone puts them ahead of schedule. Just from lowering electricity demand on the power grid during times of peak demand, solar power is estimated to have saved New York $90 million last summer. Greater savings will come this summer.

07/08/2026 Yale Environment 360 What Do We Actually Know About the Microplastics Inside Us? - I know it is easy to say we don’t have enough information yet, but we do know about [the health risks from] these chemicals that are in all the plastics that your food is wrapped in. From that perspective, it is still a good idea to reduce plastics or eliminate them where possible. – Cassandra Rauert

07/07/2026 The Conversation Island life changed how Brazil’s Noronha skink reproduces, but the lizard’s strategy might be failing in a rapidly evolving world - Reproduction occurs during a relatively narrow period of the year, in the dry season. Not all females reproduce annually: our data suggest that many reproduce only every two or even three years. When they do, they produce only two eggs at a time — a very low number for lizards in this group. These eggs, however, are large relative to the mother’s body size, indicating a high investment in each offspring.

05/20/2026 PLOS One Skeletons in the permafrost: Exploring climate-driven heritage loss and occupational health at the early modern whaling burial site of Likneset, Svalbard - Rapid Arctic warming is accelerating the degradation of permafrost-preserved archaeological sites, threatening both cultural heritage and the scientific information it contains.

07/06/2026 Clean Technica Fixing Climate Communications Part 1 - Make consequences such as your insurance bill, your home, and your children’s health urgent and tangible; make the cause concrete by anchoring every message to pollution rather than climate change; and make the cure feel expansive rather than restrictive. Reaching enough people to sustain the transition will require a delivery infrastructure built around genuine community engagement, economically grounded wins, and a willingness to hold accountable the interests that have made this conversation harder than it needs to be.

07072026 Clean Technica Climate Communications — From Losing the Argument to Winning It Part 2 - Telling the climate story with the value proposition of cost, risk management, improved operational performance, supply chain resiliency, and long-term enterprise value is a winning one. It’s a strategy that appeals to the C-suite, is durable, and can be couched in shareholder returns.

07/06/2026 Smithsonian Magazine These 11 Wildlife Images from the Ocean Conservancy’s Photography Contest Showcase the Wonder of Earth’s Waters - The annual contest received more than 1,000 photographs of marine wildlife and habitats this year. The ones that rose to the top were portraits of ocean wildlife, and I think that’s because we crave to see and connect with animals on an interpersonal level.

07/07/2026 The Conversation 3.1 billion‑year‑old rocks in Australia reveal a forgotten chapter of Earth’s water cycle - We learn the water cycle in school as a story of evaporation and precipitation. But Earth runs a second, far slower one deep beneath our feet. On the ocean floor, seawater seeps into the oceanic crust and reacts with the rock, becoming chemically bound inside its minerals, locked into their crystal structures rather than sitting as free water. Over millions of years, sinking tectonic plates carry these water-bearing minerals down into the mantle, the hot rock layer beneath the crust. This sinking of one plate beneath another is called subduction, and volcanoes eventually breathe the water back out. The deep water cycle moderates Earth’s water budget. At the surface, it keeps the oceans from drying up or drowning the continents, while in the interior, it changes how the mantle melts and builds continents.

07/06/2026 NWF Blog Marine Animal Quiz: It’s Plastic Free July! - Take the time to learn more about how plastic pollution in the oceans of the world harms marine life and consider action steps you can take to reduce your plastic waste footprint.

07/04/2026 ScienceDaily The secret to healthy aging may be hidden in your blood - A new study found that centenarians have a unique chemical "fingerprint" in their blood that sets them apart from normal aging, including unusual patterns of bile acids and steroids linked to longer survival.

07/03/2026 Planetizen Lake Powell reaches lowest water level on record - Currently, Lake Powell is around 24 percent full. The last time it was completely full was in 1983. Since then, water levels have fluctuated, but in 2026, they have fallen to a critical point. And there are multiple concerns if the water levels continue to drop. One includes reaching "dead pool," the point at which water levels are so low that water can no longer move across the dam and into the Grand Canyon, which would cause significant ecological impacts and reduce the capacity for hydroelectricity. 

07/03/2026 Yale Environment 360 In Overfished Adriatic Sea, Dolphins Look to Trawlers for Food - Off the eastern coast of Italy, large numbers of bottlenose dolphins are looking to fishing trawlers as a source of food, a sign that dolphins may be struggling to feed themselves in waters depleted by overfishing. Dolphins may also suffer hearing damage that results from chronic exposure to the noise of trawlers. It is risky behavior. However, finding sufficient prey away from trawlers in an overfished sea may be too difficult. It appears that for these animals, taking the risks is better than going hungry.

7/2/2026 Smithsonian Magazine Earth Might Be Home to 20 Million Insect Species—More Than Three Times as Many as Previously Thought – Only about one million species have been named and described, meaning up to 95 percent of the planet’s insect diversity might remain a mystery…. With more than 40 percent of known insect species threatened with extinction. “The library is being burned before the books can be read.”

Suburban Savana – 4

Continuing my series on my progress toward transitioning my yard to a suburban savanna…..

This month I am focusing on water. My yard has a sprinkler system that was installed in the late 90s. We get it checked at the beginning of each season and replaced the controller last year so that it doesn’t come on if there was rain recently (prior that that we often manually turned if off earlier in the growing season when our area gets enough rain for plants to thrive).

This year I am watering as I have in years past since so many of the plants are new. Next year I will likely reduce either the duration or the frequency since the plants are native and should thrive without extra water. In subsequent years when most plants are well established, I might simply turn on the sprinklers manually…only when there are very long periods with no rainfall (i.e. in drought conditions).

The only plant that will likely need extra attention is an Kousa dogwood (planted by a previous owner) that is growing in full sun. Even with the watering I do now, it tends to get some dry/brown leaves in summers with high heat and little rain. It’s not a native so obviously is not honed to our Missouri climate! I might put a soaker hose in to specifically provide water to the roots of the tree….or plant some green native ground cover (something like golden ragwort on the north and south, Missouri evening primrose on the western side, violets on the eastern side) under the tree that will keep the soil cooler than the mulch that is currently there.  

In a few years, if something on the sprinkler system breaks enough that it would required replacement – maybe I will decide I don’t need a sprinkler system often enough to warrant the expense!

More about my suburban savanna and blooms for pollinators next month.

New Madrid County recorded the worst air quality in the United States before idling.

07/01/2026 Yale Environment 360 A Home Battery Revolution Is Reshaping the Power Grid - As residential batteries have become more energy dense, cheaper, and smaller, more households are storing their excess solar power. Now, utilities and energy companies in dozens of countries are buying up those electrons, bundling them together, and using them to balance the grid.

07/01/2026 Planetizen Replacing lead pipes in Chicago costs more than 6 times the national average - Chicago has the nation's largest inventory of lead water pipes. Officials say replacing each one costs about $31,000 on average — more than six times the Environmental Protection Agency’s national estimate of $4,700 a line. The most significant factors driving up costs include inefficient early contracts, cumbersome permitting requirements, and the city’s reliance on one-off replacements rather than undertaking whole blocks at once.

07/01/2026 NPR Lone star ticks are covering much of the U.S. Here's what you need to know - The lone star is spreading across vast regions of the U.S., and the illness it carries, the alpha-gal syndrome, is spreading in more than 30 countries on six continents, often spread by various other ticks. The alpha-gal syndrome is more difficult to diagnose and treat than lime disease, and the symptoms are more severe. In many cases, the victim develops an allergy to all red meat, including nearly microscopic particles of it. The allergy can become so extreme it can kill you.

06/28/2026 BBC What watching the sunset really does for your health - There's growing evidence that sunsets – and sunrises, for that matter – can have a meaningful impact on our brain and mental health: diminishing anxiety and depression while boosting memory, creativity, sleep and even altruism. 

6/25/2026 The Conversation Most bees are solitary and don’t live in hives. Climate change risks them starving - Currently, most of what we know about bee nutrition comes from highly social species such as honeybees or bumblebees. Yet most bees are solitary or communal (group living but with no queens and workers). They might experience the nutritional landscape and nutritional stress in very different ways.

06/22/2026 NASA A Turquoise Tint for the Black Sea - The Black Sea sits at the boundary between Europe and Asia and connects to the Mediterranean Sea via a chain of waterways. Its surface often appears dark, but each spring and summer it transforms into a striking expanse of swirling turquoise. The turquoise color is likely caused by coccolithophores, a type of phytoplankton covered with calcium carbonate plates that can give surface waters a milky-blue appearance. These types of phytoplankton tend to dominate in late spring and early summer. Other times of the year, diatoms—a type of microscopic algae with silica shells—can become more prevalent, and they tend to darken the water rather than brighten it.

6/27/2026 Science Daily Yellowstone’s supervolcano may be fueled by something unexpected - Instead of a deep plume rising from near Earth’s core, a broad “mantle wind” may push hot rock beneath Yellowstone, generating magma closer to the surface. This process helps create a massive underground magma network and may explain how supervolcanoes remain active for long periods.

Five Years from Now

During my career – there were development plans that addressed ‘what do I want to be doing 5 years from now…and what can I do to prepare myself?” I am trying to apply the idea to my post-career life – which does not have salary as a motivating factor. My overarching goal is to become wiser every year…to care for my family…to contribute to the well-being of my community….to blend the things I do rather than trying to separate them.

In 5 years, I want to be much as I am now…but better prepared for whatever health/infirmity develops as I get older and take more action to leave the world a better place.

Here is my high level “what I can do to prepare myself:”

  • Continue doing what I am doing now with some changes

  • Consciously increase activities that sustain or improve my physical resilience (i.e. targeted exercise primarily)

  • Decrease my carbon footprint. Here are some things I have in mind:

    • Replace my plug-in hybrid car with an electric. This will probably happen in 2027.

    • Put solar panels with battery on my home. This will probably happen in the next 2 years.

    • Eat more from my own yard (I already eat seasonal greens from the yard….and am looking forward to elderberries and pawpaws in the coming years).

    • Gradually replace my wardrobe with clothes made from natural fibers.

    • Reduce the turf in my yard to 30% or less.

    • Allow an oak to grow in both the back and front yard (they as seedlings now).

  • (Maybe) Begin to skew from outreach/education type volunteering toward advocacy. This could mean that I would decide not to continue as a Missouri Master Naturalist.

Now that I have written this down, I realize that my trend is good….that the plan is simply tweaks that will take some disciple/energy to implement.

06/24/2026 I’m Plastic Free How to Tell if a Company is Actually Reducing its Plastic Footprint? - In the 2020s, it is no longer enough for companies to say they care about the planet while their products, packaging, and supply chains continue to leak plastic into the environment. Plastic pollution is not only a litter problem. It is a materials, design, energy, waste, and accountability problem.

6/24/2026 NWF Blog Go Plastic Free This July - Reducing our plastic waste helps the environment by not only ensuring it’s pristine, but it also prevents plastic from being ingested by wildlife, where injury and death are common outcomes when they interact with plastic. Plastic is also a known hormone disruptor, which can and does affect wildlife and humans.

06/23/2026 The Conversation We found microplastics in hedgehogs – then we traced them back to pet food - The story began in 2021, when we collected 189 hedgehog faeces samples from residential gardens and rehabilitation centres across the UK. We found plastic in 19% of them. Research suggests that food left out by people is the single biggest reason European hedgehogs visit residential gardens. Many hedgehogs have even become reliant on it, especially during the autumn and winter. We found microplastics in 29 of the 38 pet food products we tested. In 18 products, contamination appeared in more than one retail unit. Although plastic was found across the products tested, those in the “value” price category had more positive samples.

06/23/2026 The New York Times Former NOAA Employees Revive Climate Site Shut by Trump Administration - The new site, climate.us, is an effort by former staff members at the National Oceanic and Atmospheric Administration to present climate science previously housed at climate.gov, including data, reports, articles, and congressionally mandated national climate assessments. The new site is effectively the “first full clone” of climate.gov.

6/23/2026 Clean Technica How you fight climate disinformation – Several strategies….including Pope Leo XIV has called “the drug of fake news” a threat to a health society and has called on journalists to “safeguard voices and faces, cultivate seriousness in every report and every analysis, preserve the beauty of cultures and territories.”

6/25/2026 BBC Droughts are transforming the Turkish landscape with massive sinkholes - The "breadbasket" of Turkey, Konya's valleys are filled with the farms needed to feed a growing nation. But the available groundwater is drying up and causing fields to collapse. Turkey has been seized by ongoing drought, with a United Nations report predicting that Turkey would become a water-poor country by 2030. Konya's sinkhole problem is a perfect storm of geology, drought and intensive agriculture draining the groundwater.

6/25/2026 Science Daily Osteopenia is silently weakening bones in millions of people - Exercise, adequate calcium and vitamin D, and other healthy habits can slow or even partially reverse the decline.

6/23/2026 The Conversation Earth’s oldest crater really is over 3 billion years old - Zircon is tiny, tough and unusually good at keeping time. It contains uranium, which slowly decays into lead. By measuring uranium and lead in a zircon crystal, we can estimate when that crystal formed, or when something strongly altered it. Apatite can grow when hot fluids move through broken rock – exactly the kind of system an impact creates, as heat and fractures drive water through a crater. The apatite gave the same age as the modified zircons. Two clocks, in different minerals and different rocks, pointed to the same event about 3.02 billion years ago.

6/22/2026 Smithsonian Magazine Authorities Investigated Reports of an Illegal Excavation in Rome. Then, They Stumbled Upon an Ancient Villa Adorned with Mosaics - In mid-February, residents of Castel di Guido, a village on the outskirts of Rome, notified police of unusual activity taking place nearby. Locals had spotted people digging at night, seemingly without authorization. When authorities investigated the site, they realized that looters had used a backhoe to access an underground cavern protected by fencing. Archaeologists jumped into action to prevent further damage—and soon discovered a well-preserved set of ruins that may have been visited by Roman emperors. Emergency excavations revealed the ancient structure’s entrance hall, which featured a central impluvium, or marble basin at the center of the room, and a mosaic floor adorned with botanical and geometric designs.

6/17/2026 Yale Environment 360 A Missing Piece in Climate Models: Nature’s Own Emissions - For decades, climate scientists have issued warnings about positive global warming feedbacks, vicious cycles in the Earth system in which rising temperatures from burning fossil fuels beget more warming. Feedbacks in which ecosystems emit more greenhouse gases to the atmosphere are so complex that they are often left out entirely. For example, how much more carbon dioxide will be emitted as wildfires increase? How much more methane will bubble up from fermenting wetlands or seep from thawing permafrost? Remarkably, these so-called warming-induced emissions are poorly represented or absent from the most influential climate models. Climate modelers are scrambling to catch up.

06/17/2026 Science Daily Scientists say most of what’s in your food is still a mystery - Most chemicals in food are invisible to us in terms of research. We consume them every day, but we have little idea what they do. Projects such as the Foodome Project are now attempting to catalogue this hidden chemical universe. More than 130,000 molecules have already been listed, linking food compounds to human proteins, gut microbes and disease processes. The aim is to build an atlas of how diet interacts with the body, and to pinpoint which molecules really matter for health.

06/17/2026 The Conversation Levels of ‘forever chemicals’ in dolphins and whales are rising globally - Whales and dolphins inhabit some of the largest and seemingly most pristine environments on Earth, from tropical coastlines to Antarctic waters. Yet even they cannot escape PFAS – persistent “forever chemicals” that leak from our homes, factories and waterways into the sea. Whales and dolphins inhabit some of the largest and seemingly most pristine environments on Earth, from tropical coastlines to Antarctic waters. Yet even they cannot escape PFAS – persistent “forever chemicals” that leak from our homes, factories and waterways into the sea. Some dolphin studies have reported changes in immune-related markers associated with PFAS exposure. The highest concentrations tended to be found in coastal dolphins and porpoises, suggesting animals living near urban and industrial areas face greater exposure.

06/15/2026 Smithsonian Magazine Venus Flytraps Snap Their Traps Shut in Less Than a Second - A team reports that the chomping motion happens when rigid walls of cells on the leaves’ outer surface suddenly soften. The findings provide new insights into plant biology and could inspire new robotic designs.

6/16/2026 The Conversation Microplastics are everywhere in Pennsylvania’s water – but the tide may be turning - Microplastics are nearly everywhere, their concentration in sediment has been doubling every 20 years, and some of the most common types are among the most toxic. More than 80% of mismanaged plastic waste - plastic that’s littered, dumped or otherwise not properly contained - is estimated to be transported by rivers to coastal environments. What can you do to decrease your exposure to microplastics and help decrease their spread? You can stay informed about which plastics carry the greatest health risks and check the recycling number on the bottom of containers before you buy. You can also swap out single-use plastic cups, straws and food containers for alternatives, such as glass, stainless steel or unbleached paper.

06/11/2026 NASA Air Pollution’s Daily Pulse Over the Northeast - More than 35 million people live along the New York–Washington corridor and breathe the region’s air. While air quality has improved significantly in recent decades, outbreaks of ground-level ozone remain common, particularly in the warm summer months, when the chemical reactions that produce the pollutant accelerate and stagnant air allows ozone to accumulate. A reminder of this seasonal phenomenon came earlier than usual in 2026, when a mid-May heat wave prompted the New York State Department of Health and the New York Department of Environmental Conservation to issue a health advisory on May 17 over concerns about ozone.

06/13/2026 Clean Technica Solar & Storage Provide Over 90% of All New Power Added to the U.S. Grid in Q1 - The United States added 7.8 gigawatts (GW) of new solar capacity in the first quarter of 2026, surpassing 6 million cumulative installations as solar remained the leading source of new power added to the grid. Despite changing tax policy and regulatory actions targeting clean energy, solar and energy storage represented 91% of new capacity installed in Q1 as utilities, homeowners and businesses seek energy security amid global gas and gas turbine supply disruptions.

03/17/2026 National Geographic To study microplastics, Cassandra Rauert first had to build a plastic-free lab. It wasn't easy - An air-locked, 250-square-foot facility built almost entirely from stainless steel and nicknamed “the submarine”—though it feels less like a sub and more like a starship from a galaxy where plastic never took over modern life. Known as the Minderoo Plastics and Human Health Laboratory

06/09/2026 Science Daily An invisible forever chemical rain is falling across the planet - Researchers found that refrigerants and certain anesthetic gases have generated more than 335,000 tons of trifluoroacetic acid (TFA), a highly persistent "forever chemical," that has been deposited across Earth's surface since 2000. The pollutant is now showing up everywhere from rainwater to remote Arctic ice, and scientists expect levels to keep rising. Scientists are still working to fully understand the long-term effects of TFA. The European Chemicals Agency classifies the chemical as harmful to aquatic life. Researchers have also detected TFA in human blood and urine. In addition, the German Federal Office for Chemicals recently proposed classifying TFA as potentially toxic to human reproduction.

06/09/2026 National Wildlife Federation Data Centers are Driving Up Your Energy Bill - Clean energy has become the cheapest form of energy, but wind and solar still only account for 17 percent of the country’s energy generation. The biggest barrier to deploying clean energy is usually transmission. Without enough transmission to deliver cheaper clean energy to where it’s needed, over 900 GW of solar and wind projects sit waiting in queue, and utilities often default to more expensive fossil fuel generation instead. We can double down on outdated systems that pollute our air and water and drive up prices, or we can invest in the resilient energy solutions that have proven to be the cheapest, build the grid needed to deliver them, and ensure the largest electricity users pay their fair share of the costs they trigger.

06/08/2026 National Parks Traveler Young Mountains, Old Rocks: A Geological Overview of the Teton Range - The Tetons continue to grow. The tectonic forces that built the range are still active, and stress continues to build even if the Teton Fault has not experienced major movement in recorded history. Evidence of ongoing stress appears east of the Teton Range, where the Snake River does not flow down the center of its riverbed. Instead, the river flows preferentially along the western side of its banks as the extensional stress builds and the eastern block of the fault (the block underlying Jackson Hole) tilts more westward.

Missouri Master Naturalist Conference Keynote

The keynote speaker at the Missouri Master Naturalist state conference was Phil Valko – the Assistant Vice Chancellor for Sustainability at Washington University. He was an engaging speaker…starting his talk with a Missouri nature trivia quiz (number of springs and caves, etc.) and conservation history.

The major topic of the talk was sustainability at Washington University. I had already noticed the number of native plants in the areas of the campus I encountered during the conference. It was great news that they had successfully reduced the campus energy use and emissions while increasing the campus space! They have electrified their fleet and have solar panels on their charging facility.

The campus as its own thrift store to promote reuse – particularly during student move in and out at the university.

The campus also is an arboretum. It has 133 of the 153 trees native to Missouri and 63 of the 113 shrubs! The arboretum also has many non-natives….and the current logo for the arboretum features the ginkgo.

Washington University created a mobile app (Project Clean Grid) that displays a specific type of grid emissions data called marginal emissions that focus on the real-world impacts of using electricity – which power plants actually respond when you use more or less electricity and how much carbon they emit. By avoiding the dirtiest times (red and orange), high-carbon power plants run a little less. Shifting your usage to the cleanest times (green) makes use of lower-carbon power sources in your region and can even result in more renewable energy flowing onto the grid in regions with significant amounts of clean energy. I downloaded the app and have started to be more aware of the grid where I live.

Benefits of Riparian Corridor

My second lecture session at the Missouri Master Naturalist state conference was Brian Waldrop’s Benefits of Riparian Corridor. Most of the material was not new to me,  but it was thought provoking.

There was a chart about different types of riparian corridors: forest, grassland, mixed, and wetland. I realized that the one I was most familiar with was forest (most of the time in an urban environment where the corridor was damaged by intermittent intrusion of heavy runoff that often undermined the trees. A stream in a tropical forest was shown with vegetation hanging well over the stream surface.

The wider the buffer, the greater the benefit - starting with bank stabilization and progressing to water quality, flood control, and wildlife habitat. In urban/suburban areas, we often think it is great if we can achieve bank stabilization!

It seemed logical that the type of plants found in riparian zones should be native, flood-tolerant, deep-rooted, and shade-providing. I realized that I don’t know these things about individual plant species. I tend to draw on memories of trees seen frequently along rivers in Maryland and in Missouri – like American sycamores!

The talk ended with some charts about good reverences. I am putting them on my list of books to browse online!

Conservation Planning Tools for Missouri Communities: A Reference Manual (from MDC)

Native Plants for Stormwater Management Projects (from Grow Native!)

Stormwater Smart Outreach Tools (US EPA)

Ecological Practices with Native Plants

My first lecture associated with the Missouri Master Naturalist state conference was Jean Ponzi’s Ecological Practices with Native Plants. It followed my morning at the Zoo and Center for Hellbender Conservation tour. It was good to spend the afternoon indoors!

I remembered that I could use my phone to photograph some of the key charts. The first was to remind me that Grow Native! has a model ordinance about native plants and urban landscape design. It is unfortunate that is necessary – but modern urban/suburban yard ‘rules’ tend to skew toward shallow rooted turf and result in relatively sterile outdoor spaces….not what we want to sustain the planet. The second photograph was the definition of ‘green infrastructure.’

Doug Tallamy’s work was cited….and the https://homegrownnationalpark.org/ was talked about. I had heard of it before and, now that I am reducing the turf in my yard – maybe I should look into it more.

One of the quotes I liked from this speaker: “Turf is living concrete!”

06/05/2026 CNN Health Ultraprocessed food scientists say Americans are ‘fed up’ with industry and government inaction - Up to 70% of Americans want companies banned from advertising ultraprocessed foods on children’s television, while up to 87% want government safety testing for all laboratory-made chemicals long before they can be used in any food product, according to the survey published in the American Journal of Public Health. According to the US Centers for Disease and Prevention, 53% of American adults get most of their calories from ultraprocessed foods. For children ages 1 to 18, the percentage rises to 62%.

06/04/2026 The Conversation Poison or poverty: the impossible economic choices facing Ghana’s e‑waste workers - Agbogbloshie, in Ghana’s capital city, Accra, is a sprawling, open-air scrapyard located next to a lagoon and a growing informal settlement. Roughly 6,000 people dismantle, recycle and burn old and broken electronics there. Informal recycling provides an income for workers which is often relatively better than other available work. But the side effects of burning plastic and metal or using acid to extract minerals from the e-waste are devastating to human health and the natural environment.

06/05/2026 The Conversation A lot of ‘recycled’ plastic is being burned overseas – and causing widespread pollution linked to health problems - A large amount of plastic waste gets shipped overseas.  A new study analyzed what happens when plastic waste is shipped to lower- and middle-income countries, where open burning is a common way of dealing with excess waste. The study found pronounced increases in toxic air pollution. When plastic burns, it releases particularly toxic air pollutants. Fine particles can penetrate deep into people’s bodies, along with gases that include carbon monoxide, styrene gas and hydrogen cyanide. It also releases persistent organic pollutants such as polycyclic aromatic hydrocarbons and dioxins. These particles and gases have been linked to health risks ranging from respiratory and cardiovascular disease to cancer and reproductive and neurological disorders. Since 2021, seven states have enacted extended producer responsibility laws focused on packaging: Maine, Oregon, California, Colorado, Minnesota, Washington and Maryland. However, it will take time to see the effects.

06/02/2026 YaleEnvironment360 Tire Pollution May Threaten Human Health, Study Finds - Tiny particles of rubber cast off by car tires, which have long been known to harm wildlife, may also pose a risk to humans.

05/06/2026 Toxic-Free Future Endocrine-Disrupting Plastic Chemicals in Breast Milk - Testing found bisphenols, melamine and related chemicals, and triclosan in breast milk samples, pointing to widespread exposure from everyday products and materials, including plastics, food-contact materials, receipts, antimicrobial treatments, and many other products. To understand the potential health risks from tire pollution, researchers exposed human immune cells to a mixture of tire-derived pollutants as well as 6PPD-quinone (one of the known pollutants from tire rubber) on its own. The mixture caused rapid cell death, among other harms.

05/18/2026 NPR Thousands of U.S. countertop workers could have damaged lungs - Occupational health experts who have petitioned California to ban quartz say this material "is too toxic to fabricate and install safely, and education and enforcement alone will not be sufficient to curtail the escalating occupational health emergency caused by this product. A few weeks ago, in the first quartz and silicosis lawsuit to come to trial outside of California, a jury in Colorado awarded damages to an injured worker - finding that actions by several companies led to his illnesses. 

05/19/2026 Planetizen Public works officials indicate alarming decline in condition of water and sewer systems - According to a survey in the National League of Cities’ 2026 Municipal Infrastructure Conditions Report, the confidence of public works and city officials in their water systems has dropped significantly, with just 39% of officials surveyed saying their own water and sewer infrastructure is 'satisfactory,' down from 82% in 2022.

05/30/2026 Clean Technica Illinois First Great Lakes State to Enact Plastic Pellet Pollution Law - Just days before the end of the 2026 legislative session, the Illinois state legislature passed HB4418, which defines pre-production plastic pellets as a pollutant and gives the Illinois Environmental Protection Agency the authority to establish policies to prevent them from being released into the environment. eople complain about government overreach and faceless bureaucrats, but the truth is that without legislation such as this and governmental organizations like the Illinois EPA to enforce it, the world would be a much more toxic and dangerous place. It is long past time to stop giving polluters a free pass so they can maximize their profits.

05/11/2026 RNZ Is it really possible to live a plastic-free life? - Our lives are riddled with plastic, and growing evidence suggests it is affecting our health in myriad ways. (New Zealand)

04/27/2026 Journal of Exposure Science & Environmental Epidemiology Endocrine-disrupting chemicals in breast milk and early life exposure for infants in the United States – Melamine, cyanuric acid, BPA, BPS, and triclosan were detected with high frequency in breast milk samples in the study, and our study suggests that breast milk is an important exposure pathway for these chemicals among nursing infants. Given the importance of breastfeeding for infant health, our study highlights the need to investigate potential health effects of these chronic exposures.

04/26/2026 Earth.com Plastics are entering food crops and stunting their growth - Farmers, waste managers, and regulators now face a harder truth: plastic in soil can slow crops, gather around roots, and enter plants. The next step is tracing whether weathered nanoplastics reach edible tissues at harvest and deciding which plastic inputs should be cut first.

04/02/2026 Medical Xpress Seven days without plastic contact slashes phthalates and bisphenols in body – A clinical trial investigating levels of plastic chemicals in the human body has found that a low-plastic diet could be a fast and effective way to reduce exposure. (Australia)

05/31/2026 The Conversation Trees and greenery can cool cities by as much as 18°C – but only if it’s the right type - Field measurements from Melbourne, Munich and Hong Kong were compared to test how different kinds of urban planting changed the heat people experience outdoors. Layered vegetation – where trees are combined with shrubs and ground cover – often cooled cities more effectively than trees alone. We also found local climate and street design strongly shaped whether greening worked well. Cities need planting strategies tailored to local conditions rather than universal greening formulas. In parks and open green spaces, layered vegetation can provide strong cooling while also supporting biodiversity. In dense streets, planners may need to balance shade with ventilation.

05/28/2026 My Modern Met Hand-Colored Photos From 19th-Century Japan Offer a Glimpse of Traditional Life - Photography arrived in Japan very early—a little less than a decade after it was invented in Europe. Throughout the 1850s, as Japan opened up to foreigners, the images from this time capture not only a nearly forgotten moment in history but also a rare transitional time in which traditional Japanese life was being affected by rapid modernization.

05/20/2026 BBC Chile's Atacama Desert is one of the darkest places on Earth. But now the light is intruding - The battle against encroaching artificial light in the Atacama is a microcosm of a global problem. As electric bulbs have proliferated, around 80% of Earth's population now lives under light-polluted skies. A recent study of star visibility found that, on average globally, the sky brightened due to light pollution by almost 10% a year between 2011-2022. If a person could see 250 stars at the start of the period, the researchers found, they would only spot 100 by the end.

5/28/2026 Smithsonian Magazine Giant, Destructive Hail Is Becoming More Common with Climate Change - A new study finds that these giant hailstones will become more common as the climate warms from human-caused carbon emissions. In models of predicted future warming, the researchers found that the frequency of hail larger than a marble will increase 47 percent by 2100 in a worst-case scenario. Even in a more optimistic model of future climate change, the potential for storms producing giant hail will rise 38 percent.
