This isn’t the first time this has happened. It happened in 2021, when more than 200 Texans died because of power outages from extreme cold. Massive outages also happened with Hurricanes Harvey and Ike. More than 15 years after Ike, there is still no “Ike Dike.”

Why the health risks from air pollution could be worse than we thought

A new study found elevated and previously overlooked health risks for communities living near industrial polluters.

Many people who live near heavy industry are routinely exposed to dozens of different pollutants, which can result in a multitude of health problems.Traditionally, environmental regulators have assessed the risks of chemical exposure on an individual basis. But that approach has led to underestimates of the total health risks faced by vulnerable populations, according to a new study.Now researchers at Johns Hopkins University have developed a new method for measuring the cumulative effects on human health of multiple toxic air pollutants. Their findings were published last week in Environmental Health Perspectives.Regulators typically measure community risk by looking at the primary health effects of individual chemicals, an approach that often fails to address their combined risks, said Keeve Nachman, the study’s senior author.Residents in disadvantaged communities are exposed to a toxic stew of chemicals daily, and they “don’t just breathe one at a time, [they] breathe all the chemicals in the air at once,” said Peter DeCarlo, another of the study’s authors.Follow Climate & environment“Very little has happened to protect these people. And one of the major reasons for that is that current approaches have not done a good job showing they’re in harm’s way,” Nachman said.“When we regulate chemicals, we pretend that we’re only exposed to one chemical at a time,” Nachman continued. “If we have each chemical and we only think about the most sensitive effect, but we ignore the fact that it could potentially cause all these other effects to different parts of the body, we are missing protecting people from the collective mixture of chemicals that act together.”Nachman, DeCarlo and their colleagues set out to more accurately account for the total burden of breathing multiple toxic air pollutants.The study assessed the risks faced by communities in southeastern Pennsylvania living near petrochemical facilities using a mobile laboratory to measure 32 hazardous air pollutants, including vinyl chloride, formaldehyde and benzene. The researchers developed real-time profiles of the pollution concentrations in the air and translated them into estimates of what people are actually breathing.Using these estimates and a database of the chemicals’ toxic effects on various organs, the researchers created projections of the long-term cumulative health impacts of the pollution.By looking past the immediate health effects of chemicals and measuring what happens as concentrations increase, negative health outcomes can be detected in other parts of the body, Nachman said.For example, while EPA risk assessments consider only the respiratory effects of formaldehyde, the study found potential health impacts in 10 other organ systems, including neurological, developmental and reproductive harms.The cumulative risk study appears at a fraught moment for environmental regulation. Although the Biden administration in November released a draft framework for monitoring the cumulative impact of chemical exposure, the Trump administration has announced plans to roll back dozens of Biden administration environmental rules and is considering shutting down the EPA’s Office of Research and Development.A spokesperson for the American Chemistry Council, an industry trade group, said in an email that the Johns Hopkins research “may provide some useful information” but that “further assessment, replication and validation will be needed” of the methods and substances assessed in the study.“ACC continues to support the development of scientifically robust data, methods and approaches to underpin cumulative risk assessments,” the spokesperson added.The EPA did not provide an immediate comment while it reviewed the study.Jen Duggan, the executive director of the Environmental Integrity Project, said communities often face higher health impacts than the EPA estimates due to their exposure to dangerous chemicals from multiple sources.“The authors of this paper powerfully demonstrate how EPA has repeatedly underestimated the true health risks for people living in the shadow of industrial polluters,” Duggan said.

Utah Bans Fluoride In Public Drinking Water

Republican Gov. Spencer Cox signed the legislation despite widespread opposition from dentists and national health organizations.

SALT LAKE CITY (AP) — Utah has become the first state to ban fluoride in public drinking water, despite widespread opposition from dentists and national health organizations.Republican Gov. Spencer Cox signed legislation late Thursday that bars cities and communities from deciding whether to add the mineral to their water systems.Fluoride strengthens teeth and reduces cavities by replacing minerals lost during normal wear and tear, according to the U.S. Centers for Disease Control and Prevention.Utah lawmakers who pushed for a ban said putting fluoride in water was too expensive. Cox, who grew up and raised his own children in a community without fluoridated water, compared it recently to being “medicated” by the government.The ban comes weeks after U.S. Health Secretary Robert F. Kennedy Jr., who has expressed skepticism about water fluoridation, was sworn into office.More than 200 million people in the U.S., or almost two-thirds of the population, receive fluoridated water through community water. The addition of low levels of fluoride to drinking water has long been considered one of the greatest public health achievements of the last century.But some cities across the country have gotten rid of fluoride from their water, and other municipalities are considering doing the same. A few months ago, a federal judge ordered the U.S. Environmental Protection Agency to regulate fluoride in drinking water because high levels could pose a risk to the intellectual development of children.We Don't Work For Billionaires.

Low-income families may not be able to afford regular dentist visits or the fluoride tablets some people buy as a supplement in cities without fluoridation.The sponsor of the Utah legislation, Republican Rep. Stephanie Gricius, acknowledged fluoride has benefits, but said it was an issue of “individual choice” to not have it in the water.

Dozens of House Democrats push back on planned EPA research and development cuts

Dozens of House Democrats pushed back on planned Environmental Protection Agency (EPA) cuts in a Thursday letter to the agency. “We are particularly concerned by the proposal to eliminate up to 75 percent of employees within EPA’s Office of Research and Development (ORD),” the letter, from Rep. Greg Landsman (D-Ohio) and addressed to EPA Administrator...

Dozens of House Democrats pushed back on planned Environmental Protection Agency (EPA) cuts in a Thursday letter to the agency. “We are particularly concerned by the proposal to eliminate up to 75 percent of employees within EPA’s Office of Research and Development (ORD),” the letter, from Rep. Greg Landsman (D-Ohio) and addressed to EPA Administrator Lee Zeldin, reads. “Firing nearly 1,200 dedicated ORD public servants across the country would decimate the scientific backbone of EPA which provides independent, objective, and unparallelled research that informs Agency assessments and decision-making,” they added. The letter featured the signatures of over 60 House Democrats including Reps. Nikema Williams (Ga.), Ro Khanna (Calif.), Summer Lee (Pa.), Don Beyer (Va.), Joe Neguse (Colo.), Jamie Raskin (Md.), Pramila Jayapal (Wash.) and Rashida Tlaib (Mich.). The Hill reported last week that the EPA was considering the cutting of its science arm and dropping most of the employees of the branch, per documents reviewed by Democratic staff for the House Science, Space and Technology Committee. The termination of the Office of Research and Development as an EPA National Program Office is called for in a plan reviewed by committee staffers. Fifty percent to 70 percent of the 1,540 staffers in the office would be cut under the plan. “While no decisions have been made yet, we are actively listening to employees at all levels to gather ideas on how to better fulfill agency statutory obligations, increase efficiency, and ensure the EPA is as up-to-date and effective as ever,” EPA spokesperson Molly Vaseliou said in a previous statement. In his letter, Landsman said dropping “the majority of ORD employees would be particularly harmful to EPA’s work to address industrial pollution, contaminated air and drinking water, environmental health, and worsening natural disasters.” The Ohio Democrat also questioned the EPA about the reasoning behind the staff cuts in the plan and the way the agency is prepping “to mitigate the loss of scientific expertise, institutional knowledge, and subject matter capacity resulting from this proposed action.” The Hill has reached out to the EPA for comment.

When a 1-in-100 year flood washed through the Coorong, it made the vital microbiome of this lagoon healthier

The 2022 floods triggered shifts in the Coorong’s microbiome—similar to our gut bacteria on new diets—revealing why freshwater flows are vital to wetland health.

Darcy Whittaker, CC BYYou might know South Australia’s iconic Coorong from the famous Australian children’s book, Storm Boy, set around this coastal lagoon. This internationally important wetland is sacred to the Ngarrindjeri people and a haven for migratory birds. The lagoon is the final stop for the Murray River’s waters before they reach the sea. Tens of thousands of migratory waterbirds visit annually. Pelicans, plovers, terns and ibises nest, while orange-bellied parrots visit and Murray Cod swim. But there are other important inhabitants – trillions of microscopic organisms. You might not give much thought to the sedimentary microbes of a lagoon. But these tiny microbes in the mud are vital to river ecosystems, quietly cycling nutrients and supporting the food web. Healthy microbes make for a healthy Coorong – and this unassuming lagoon is a key indicator for the health of the entire Murray-Darling Basin. For decades, the Coorong has been in poor health. Low water flows have concentrated salt and an excess of nutrients. But in 2022, torrential rains on the east coast turned into a once-in-a-century flood, which swept down the Murray into the Coorong. In our new research, we took the pulse of the Coorong’s microbiome after this huge flood and found the surging fresh water corrected microbial imbalances. The numbers of methane producing microbes fell while beneficial nutrient-eating bacteria grew. Populations of plants, animals and invertebrates boomed. We can’t just wait for irregular floods – we have to find ways to ensure enough water is left in the river to cleanse the Coorong naturally. Under a scanning electron micrograph, the mixed community of microbes in water is visible. This image shows a seawater sample. Sophie Leterme/Flinders University, CC BY Rivers have microbiomes, just like us Our gut microbes can change after a heavy meal or in response to dietary changes. In humans, a sudden shift in diet can encourage either helpful or harmful microbes. In the same way, aquatic microbes respond to changes in salinity and freshwater flows. Depending on what changes are happening, some species boom and others bust. As water gets saltier in brackish lagoons, communities of microbes have to adapt or die. High salinity often favours microbes with anaerobic metabolisms, meaning they don’t need oxygen. But these tiny lifeforms often produce the highly potent greenhouse gas methane. The microbes in wetlands are a large natural source of the gas. While we know pulses of freshwater are vital for river health, they don’t happen often enough. The waters of the Murray-Darling Basin support most of Australia’s irrigated farming. Negotiations over how to ensure adequate environmental flows have been fraught – and long-running. Water buybacks have improved matters somewhat, but researchers have found the river basin’s ecosystems are not in good condition. Wetlands such as the Coorong are a natural source of methane. The saltier the water gets, the more environmentally harmful microbes flourish – potentially producing more methane. Vincent_Nguyen The Coorong is out of balance A century ago, regular pulses of fresh water from the Murray flushed nutrients and sediment out of the Coorong, helping maintain habitat for fish, waterbirds and the plants and invertebrates they eat. While other catchments discharge into the Coorong, the Murray is by far the major water source. Over the next decades, growth in water use for farming meant less water in the river. In the 1930s, barrages were built near the river’s mouth to control nearby lake levels and prevent high salinity moving upstream in the face of reduced river flows. Major droughts have added further stress. Under these low-flow conditions, salt and nutrients get more and more concentrated, reaching extreme levels due to South Australia’s high rate of evaporation. In response, microbial communities can trigger harmful algae blooms or create low-oxygen “dead zones”, suffocating river life. The big flush of 2022 In 2022, torrential rain fell in many parts of eastern Australia. Rainfall on the inland side of the Great Dividing Range filled rivers in the Murray-Darling Basin. That year became the largest flood since 1956. We set about recording the changes. As the salinity fell in ultra-salty areas, local microbial communities in the sediment were reshuffled. The numbers of methane-producing microbes fell sharply. This means the floods would have temporarily reduced the Coorong’s greenhouse footprint. Christopher Keneally sampling for microbes in the Coorong in 2022. Tyler Dornan, CC BY When we talk about harmful bacteria, we’re referring to microbes that emit greenhouse gases such as methane, drive the accumulation of toxic sulfide (such as Desulfobacteraceae), or cause algae blooms (Cyanobacteria) that can sicken people, fish and wildlife. During the flood, beneficial microbes from groups such as Halanaerobiaceae and Beggiatoaceae grew rapidly, consuming nutrients such as nitrogen, which is extremely high in the Coorong. This is very useful to prevent algae blooms. Beggiatoaceae bacteria also remove toxic sulfide compounds. The floods also let plants and invertebrates bounce back, flushed out salt and supported a healthier food web. On balance, we found the 2022 flood was positive for the Coorong. It’s as if the Coorong switched packets of chips for carrot sticks – the flood pulse reduced harmful bacteria and encouraged beneficial ones. While the variety of microbes shrank in some areas, those remaining performed key functions helping keep the ecosystem in balance. From 2022 to 2023, consistent high flows let native fish and aquatic plants bounce back, in turn improving feeding grounds for birds and allowing black swans to thrive. A group of black swans cruise the Coorong’s waters. Darcy Whittaker, CC BY Floods aren’t enough When enough water is allowed to flow down the Murray to the Coorong, ecosystems get healthier. But the Coorong has been in poor health for decades. It can’t just rely on rare flood events. Next year, policymakers will review the Murray-Darling Basin Plan, which sets the rules for sharing water in Australia’s largest and most economically important river system. Balancing our needs with those of other species is tricky. But if we neglect the environment, we risk more degradation and biodiversity loss in the Coorong. As the climate changes and rising water demands squeeze the basin, decision-makers must keep the water flowing for wildlife.

Murphy, a Beloved Bald Eagle Who Became a Foster Dad, Dies Following Violent Storms in Missouri

A beloved bald eagle who gained popularity after incubating a rock is mourned after dying from head trauma sustained during violent storms in Missouri last week

A beloved bald eagle who gained popularity for incubating a rock in 2023 is being mourned Saturday after the 33-year-old avian died following intense storms that recently moved through Missouri. Murphy, who surpassed the average life span of 25 years, died last week at the World Bird Sanctuary in Valley Park, Missouri. Sanctuary officials believe the violent storms that ripped apart homes and claimed 12 lives last weekend may have factored in the bird's death. They said birds have access to shelters where they can weather storms and the sanctuary has contingency plans for different environmental situations. But evacuations weren't performed since no tornadoes approached the sanctuary. Three other birds who were in the same shelter with Murphy survived. A veterinarian performed a necropsy and found the bald eagle sustained head trauma. “We are unable to determine if Murphy was spooked by something and hit his head while jumping off a perch or if wind and precipitation played a part in the injury,” a statement shared by the sanctuary on social media said. Murphy lived in the sanctuary's Avian Avenue exhibit area and rose to prominence in 2023 when he incubated a rock. His instincts were rewarded when he was allowed to foster an injured eaglet that he nurtured back to health. The eaglet was eventually released back to the wild and another eaglet was entrusted to Murphy's care.
