Why this small state is picking a fight with Big Oil

Friday, June 14, 2024

Nearly a year after catastrophic flooding struck Vermont, the city of Barre confronts the overwhelming task of steeling itself for the next climate disaster.Two bridges need to be raised. Barre’s north end “literally needs to be rebuilt,” said Mayor Thom Lauzon, who was recently elected and now oversees the city’s recovery. Of the 300 properties damaged by the flooding, many are still in various states of disrepair, and at least 50 are uninhabitable.Across the country, state and local leaders are scrambling to find the money they need to protect their communities from worsening disasters fueled by climate change. For Barre, needed flood mitigation projects will cost the city an estimated $30 million over the next five years, Lauzon said.Yet Vermont has a new answer to this problem.Earlier this month, it became the nation’s first state to require fossil fuel companies and other big emitters to pay for the climate-related damage their pollution has already caused statewide. While conservative legal experts are skeptical the law will survive challenges, some Vermonters said they are both grateful and a little nervous that one of the nation’s least populous states has picked a fight with one of America’s most powerful industries.“I’m proud to have this state stand up and say, ‘Look, you need to be held accountable, and you need to help us with the damage we incurred,’” Lauzon said. “But I’m also scared to death. I feel like we’re a pee wee football team going up against the 2020 New England Patriots.”The Vermont law comes as oil and gas companies face dozens of climate lawsuits, both in the United States and abroad. While only a few have succeeded — and they are on appeal — they pose a growing threat and add to the companies’ potential liabilities. If Vermont’s novel approach endures, it could reverberate across the industry.Republicans are pushing back, arguing that individual states cannot apply their own laws to a global pollutant. Last month, Republican attorneys general in 19 states asked the Supreme Court to block the climate change lawsuits brought by California, Connecticut, Minnesota, New Jersey and Rhode Island against fossil fuel companies.Vermont’s law authorizes the state to charge major polluters a fee for the share of greenhouse gas emissions they produced between 1995 and 2024. It is modeled on the 1980 federal Superfund law, which forces polluting companies to clean up toxic waste sites.The law doesn’t spell out how much money should be paid; instead, it tasks the state treasurer with assessing the damage Vermont has suffered from climate change and what it will cost to prepare for future impacts. The final tally is expected to be comprehensive, factoring in an array of possible costs from rebuilding and raising bridges and roads to lower worker productivity from rising heat.Bills similar to Vermont’s have been introduced in several states, including California, Maryland and Massachusetts. Last week, New York lawmakers passed a climate superfund law that would require polluters to pay $3 billion a year for 25 years. It is now awaiting Democratic Gov. Kathy Hochul’s signature.The timing of the Vermont law was no accident, said Ben Edgerly Walsh, the climate and energy program director of the Vermont Public Interest Research Group. Memories of last July’s flooding, which inundated the state capitol of Montpelier, damaged thousands of homes and trapped people in small mountain towns, are still fresh.Over the last year, Vermonters have also endured a freak late-spring frost that damaged crops, hazy skies from smoke blown south from hundreds of wildfires in Canada, and more flooding in mid-December. All these events primed state lawmakers to tackle climate change at the beginning of 2024.“When we brought this idea to legislators, they came to it with a very open mind in a way that may have taken more time, more convincing, in another year,” Edgerly Walsh said. “But this was a moment we just knew we needed to act.”As disaster recovery costs mount, it has not been lost on state leaders that oil companies are enjoying massive profits. In 2023, the warmest year on record, the two largest U.S. energy companies, ExxonMobil and Chevron, together made more than $57 billion.It might seem unlikely for a state like Vermont, with a population just under 650,000, to stand up to the fossil fuel industry. The state’s Republican governor, Phil Scott, expressed skepticism in a letter to the secretary of the Vermont Senate, writing, “Taking on ‘Big Oil’ should not be taken lightly. And with just $600,000 appropriated by the Legislature to complete an analysis that will need to withstand intense legal scrutiny from a well-funded defense, we are not positioning ourselves for success.”Yet Vermont’s small budget — it has the lowest GDP in the country — means that it feels the rising risks from heavy rains more acutely than wealthier states. A report by Rebuild by Design, a nonprofit that helps communities recover from disasters, found that Vermont ranked fifth nationally in per capita disaster relief costs from 2011-2021, with $593 spent per resident.The costs are only expected to climb. A 2022 study from University of Vermont researchers predicted that the cost of property damage from flooding alone may top $5.2 billion over the next 100 years.Ultimately, the governor allowed the law to go into effect without his signature, saying he understood “the desire to seek funding to mitigate the effects of climate change that has hurt our state in so many ways.”Legal challenges will inevitably follow — the only question is when.The oil and gas industry’s top lobbying group, the American Petroleum Institute, has said that states don’t have the power to regulate carbon pollution and can’t retroactively charge companies for emissions allowed under the law. It has also emphasized individuals’ responsibility for climate change, noting that Vermont residents use fossil fuels to heat their homes and power their cars. Scott Lauermann, a spokesman for the group, said API is “considering all our options to reverse this punitive new fee.”“I think the courts are going to have problems with the idea that Vermont can penalize the companies for past actions that were completely legal and the state itself relies on,” said Jeff Holmstead, an energy lawyer who served in the Environmental Protection Agency under George W. Bush. “I’m skeptical this will actually pass muster.”Supporters and environmentalists involved in drafting the law said they believed they had created a legally defensible way to recover damages from polluters by modeling it after the Superfund law, which has been repeatedly upheld in court. Several legal experts said the state had also taken a more conservative approach than others by requiring a study before assessing companies’ liability, ensuring the fines levied against them are proportional to the amount of damage caused by their products.Cara Horowitz, executive director of the UCLA School of Law’s Emmett Institute on Climate Change and the Environment, said that, inevitably, fossil fuel companies will challenge any bills Vermont submits for damages. But that is years off, she said, and the industry is likely to move sooner than that.The lawsuits “will start soon and last a long time,” Horowitz said. “It would surprise me if they don’t preemptively try to undermine the entire exercise by declaring the whole thing unlawful.”In Barre, Lauzon said he isn’t confident litigation over the law will be resolved in his lifetime. But even if the fossil fuel companies are never made to pay, he said, the law’s passage was the right thing to do.“I can’t look at the north end, I can’t look at the city of Barre and say no one needs to be held accountable,” he said.

Vermont has enacted the first state law requiring fossil fuel firms to pay for damages caused by climate change. Will it survive a near-certain legal challenge?

Nearly a year after catastrophic flooding struck Vermont, the city of Barre confronts the overwhelming task of steeling itself for the next climate disaster.

Two bridges need to be raised. Barre’s north end “literally needs to be rebuilt,” said Mayor Thom Lauzon, who was recently elected and now oversees the city’s recovery. Of the 300 properties damaged by the flooding, many are still in various states of disrepair, and at least 50 are uninhabitable.

Greek tragedy: the rare seals hiding in caves to escape tourists

Greece is hoping that protected areas will help keep daytrippers away and allow vulnerable monk seals to return to their island habitatsDeep in a sea cave in Greece’s northern Sporades, a bulky shape moves in the gloom. Someone on the boat bobbing quietly on the water close by passes round a pair of binoculars and yes! – there it is. It’s a huge Mediterranean monk seal, one of the world’s rarest marine mammals , which at up to 2.8 metres and over 300kg (660lbs), is also one of the world’s largest types of seal.Piperi, where the seal has come ashore, is a strictly guarded island in the National Marine Park of Alonissos and Northern Sporades, Greece’s largest marine protected area (MPA) and a critical breeding habitat for the seals. Only researchers are allowed within three miles of its shores, with permission from the government’s Natural Environment and Climate Change Agency. Continue reading...

Deep in a sea cave in Greece’s northern Sporades, a bulky shape moves in the gloom. Someone on the boat bobbing quietly on the water close by passes round a pair of binoculars and yes! – there it is. It’s a huge Mediterranean monk seal, one of the world’s rarest marine mammals , which at up to 2.8 metres and over 300kg (660lbs), is also one of the world’s largest types of seal.Piperi, where the seal has come ashore, is a strictly guarded island in the National Marine Park of Alonissos and Northern Sporades, Greece’s largest marine protected area (MPA) and a critical breeding habitat for the seals. Only researchers are allowed within three miles of its shores, with permission from the government’s Natural Environment and Climate Change Agency.With a global population of under 1,000 individuals, Monachus monachus is listed as vulnerable on the IUCN Red List, reclassified from endangered in 2023, after decades of conservation efforts helped raise numbers. According to the Hellenic Society for Protection of the Monk Seal (MOm), Greece is home to about 500 monk seals (up from 250 in the 1990s), half of the global population, so has a uniquely important role to play in the future of these rare mammals. This seems fitting given that seals were once thought to have been under the protection of mythical gods Poseidon and Apollo and so have a special place in Greek culture.Monk seals have been hunted in the Mediterranean since prehistoric times for their pelts, meat and blubber. While this threat has receded in Greece, others – entanglement in fishing gear, food depletion, pollution and habitat loss – have not. Now, according to conservationists, a very modern peril is growing exponentially and putting that fragile recovery at risk: Greece’s burgeoning marine leisure industry. Unregulated tourism is having a negative impact on a mammal that is sensitive to human disturbance, say .A monk seal surfaces close to a research boat.This summer several initiatives were launched to turn this around, including Seal Greece, a national education campaign. At about the same time, the islet of Formicula, a key seal habitat in the Ionian Sea, was shielded ahead of the busy summer season by a strict 200-metre no entry zone. In October, Kyriakos Mitsotakis, the Greek prime minister, confirmed two large-scale MPAs are to go ahead. If properly managed (and so far the management structure is unclear), these MPAs could offer a lifeline to the species.Back on the waters around Piperi, Angelos Argiriou, a freelance warden and marine biologist, points as the boat passes a shore monitored by camera. “We often see the seals resting on this beach,” he says. “The fact that they feel safe enough to haul out [rest] here in the open is a really good sign that the protection measures are working.”A pup that was found orphaned is prepared for release at the Hellenic Society for Protection of the Monk Seal. Photograph: P. DendrinosSeals began to be protected in Greece in the late 1980s, with the Hellenic Society for Protection of the Monk Seal , which has rescued more than 40 orphaned or injured seals to date.“Our rehab centre has really helped the recovery of the species,” says Mom’s president, Panos Dendrinos. “Last year, we saw a rehabilitated female with a new pup. If you save one female, she might have 20 pups in her lifetime.”Monk seals once commonly gathered on beaches but many moved into caves relatively recently because of human pressure. Although pupping caves might have provided shelter from people, they have often proved an unsuitable habitat in which to raise young – violent surf can smash them against rocks, drown them or sweep them out to sea. And caves no longer provide reliable hiding places. Once-remote coastlines are now accessible to everyone from day trippers on hired boats to private yachts anchored in the seals’ habitat.“A week after giving birth, monk seal mothers go fishing, leaving their pup alone for hours,” says Dendrinos. “If someone goes inside, the pup is liable to panic and abandon the cave; its mother is unlikely to find it.”An adult female with her pup on Piperi. The island is in a marine park that protects seals so they can start to use beaches again. Photograph: P. DendrinosAfter 40 years of monitoring the Alonissos MPA, Dendrinos says his society “now see seals using open beaches systemically”.As another key habitat for seals, Formicula will be part of the new Ionian MPA. The islet is at the heart of one of the world’s busiest sailing grounds but unlike its better-known neighbours, Meganisi and Cephalonia, it did not appear much on the tourist radar until recently.Marine biologist Joan Gonzalvo from Tethys Research Institute explains how tourism has taken its toll on the area. “Six, seven, eight years ago we had encounters almost every day,” he recalls. “We would see five, six seals in the water at once, socialising, chasing each other.”But with the sightings came the tourists. “What was exciting at first quickly turned into a nightmare,” he says.The hordes came, looking for “seal experiences”, he says. Instead of studying the animals, Gonzalvo found himself recording humans chasing seals. On two occasions, people entered breeding caves, causing the separation of mothers from pups. In both cases, the pups disappeared. One day in August 2024, he says he recorded more than 50 boats around the islet’s tiny shoreline. “Nowadays,” he says, “we are lucky if we see only one or two individual seals.”Seals were once thought to have been under the protection of mythical gods Poseidon and Apollo and so have a special place in Greek culture. Photograph: Ugo Mellone/The Wild LineAs we are talking Gonzalvo spots a seal and takes out his camera. He recognises her immediately. “Mm17003,” he says, citing the number of one of more than 40 seals he has catalogued online. As the seal rolls through the water, boats pull up and anchor in the new no-entry zones while tourists swim near the protected caves.Unlike the Alonissos MPA, there are no wardens patrolling Formicula and it is down to Gonzalvo to politely point out to the boat’s skippers that they are in a forbidden area.“It’s early days,” he says. “But the inactivity [of the seals] worries me. We need serious investment on law enforcement.”In Greece, NGOs have repeatedly raised the issue of “paper parks”, with inadequate implementation. A study published last year by nine environmental organisations highlighted “only 12 (out of 174) marine Natura 2000 sites [EU protected areas] have a protective regime”, but even those were fragmented or temporary.The hope is that the new MPAs bring patrols. “The Natural Environment and Climate Change Agency needs more boats, more people,” Dendrinos says, adding that the wardens currently report to port police, “a process that is time consuming and ineffective”.At Formicula, Gonzalvo worries that time is running out. “If we are not capable of protecting this important habitat, a tiny drop in the middle of the Ionian Sea, for one of the most charismatic and endangered marine mammals on the planet, there is very little hope for anything else we want to protect in our oceans.”The sight of the animals playing in the water drew crowds of tourists looking for ‘seal experiences’.

Climate change is rewriting polar bear DNA

This story was originally published by the Guardian and is reproduced here as part of the Climate Desk collaboration. Changes in polar bear DNA that could help the animals adapt to warmer climates have been detected by researchers in a study thought to be the first time a statistically significant link has been found between rising temperatures and changing DNA in a wild mammal species. Climate breakdown is threatening the survival of polar bears. Two-thirds of them are expected to disappear by 2050 as their icy habitat melts and the weather becomes hotter. Now, scientists at the University of East Anglia have found that some genes related to heat stress, aging, and metabolism are behaving differently in polar bears living in southeast Greenland, suggesting they may be adjusting to warmer conditions. The researchers analysed blood samples taken from polar bears in two regions of Greenland and compared “jumping genes” — small, mobile pieces of the genome that can influence how other genes work. Scientists looked at the genes in relation to temperatures in the two regions and at the associated changes in gene expression. “DNA is the instruction book inside every cell, guiding how an organism grows and develops,” said lead researcher Alice Godden. “By comparing these bears’ active genes to local climate data, we found that rising temperatures appear to be driving a dramatic increase in the activity of jumping genes within the southeast Greenland bears’ DNA.” As local climates and diets evolve as a result of changes in habitat and prey forced by global heating, the genetics of the bears appear to be adapting, with the group of bears in the warmest part of the country showing more changes than the communities farther north. The authors of the study have said these changes could help us understand how polar bears might survive in a warming world, inform understanding of which populations are most at risk, and guide future conservation efforts. This is because the findings, published on Friday in the journal Mobile DNA, suggest the genes that are changing play a crucial role in how different polar bear populations are evolving. “This finding is important because it shows, for the first time, that a unique group of polar bears in the warmest part of Greenland are using ‘jumping genes’ to rapidly rewrite their own DNA, which might be a desperate survival mechanism against melting sea ice,” Godden said. Temperatures in northeast Greenland are colder and less variable, while in the southeast, there is a much warmer and less icy environment, with steep temperature fluctuations. DNA sequences in animals change over time, but this process can be accelerated by environmental stress such as a rapidly heating climate. There were some interesting DNA changes, such as in areas linked to fat processing, that could help polar bears survive when food is scarce. Bears in warmer regions had more rough, plant-based diets compared with the fatty, seal-based diets of northern bears, and the DNA of south-eastern bears seemed to be adapting to this. Godden said, “We identified several genetic hotspots where these jumping genes were highly active, with some located in the protein-coding regions of the genome, suggesting that the bears are undergoing rapid, fundamental genetic changes as they adapt to their disappearing sea ice habitat.” The next step will be to look at other polar bear populations, of which there are 20 around the world, to see if similar changes are happening to their DNA. This research could help protect the bears from extinction. But the scientists said it was crucial to stop temperature rises accelerating by reducing the burning of fossil fuels. “We cannot be complacent; this offers some hope but does not mean that polar bears are at any less risk of extinction,” Godden said. “We still need to be doing everything we can to reduce global carbon emissions and slow temperature increases.”

Supersized data centers are coming. See how they will transform America.

These AI campuses consume more power than major U.S. cities. Their footprints are measured in miles, not feet.

Supersized data centers are coming. See how they will transform America.This coal plant in central Pennsylvania, once the largest in the state, was shuttered in 2023 after powering the region for over 50 years.Earlier this year, wrecking crews blasted the plant’s cooling towers and soaring chimneys.Rising from the dust in Homer City will be a colossal artificial intelligence data center campus that will include seven 30-acre gas generating stations on-site, fueled by Pennsylvania’s natural gas boom.December 15, 2025 at 6:00 a.m. EST6 minutes agoShawn Steffee of the International Brotherhood of Boilermakers is hopeful.“The closing of the coal plant had been really brutal,” he said. “But this project just took the entire chess board and flipped it.”The Homer City facility will generate and consume as much power as all the homes in the Philadelphia urban area. It is among a generation of new supersized data centers sprouting across the country, the footprints of which are measured in miles, not feet.They are part of an AI moon shot, driven by an escalating U.S.-China war over dominance in the field. The projects are starting to transform landscapes and communities, sparking debates about what our energy systems and environment can sustain. The price includes increasing power costs for everyone and worrying surges in emissions and pollutants, according to government, industry and academic analyses.By 2030, industry and government projections show data centers could gobble up more than 10 percent of the nation’s power usage.Estimates vary, but all show a dizzying rise of between 60 and 150 percent in energy consumption by 2030. On average, they project U.S. data centers will use about 430 trillion watt-hours by 2030. That is enough electricity to power nearly 16 Chicagos.Some forecasts project it will keep growing from there.“These things are industrial on a scale I have never seen in my life,” former Google CEO Eric Schmidt told a House committee earlier this year.Power use by U.S. data centers is growing exponentially, with large forecast uncertaintySource: Washington Post analysis of IEA, BNEF, LBNL and EPRI estimates. Past uncertainty stems from varying inventories of data centers and assumptions about their utilization.Tech companies that once pledged to use clean energy alone are fast reconsidering. They now need too much uninterrupted power, too fast. According to the International Energy Agency, the No. 1 power source to meet this need will be natural gas.“While we remain committed to our climate moonshots, it’s become clear that achieving them is now more complex and challenging across every level,” Google states in its 2025 environmental impact report. The company says meeting its goal of eliminating all emissions by 2030 has become “very difficult.”Data center firms have already approached the Homer City project’s natural gas provider, EQT, seeking enough fuel to power the equivalent of eight more Homer City projects around the country, EQT CEO Toby Rice said in an interview. And EQT is just one of dozens of U.S. natural gas suppliers.What’s at stakeData centers’ surging electricity needs are straining America’s aging power grid and undercutting tech companies’ climate goals.A single supersized “data campus” would draw as much power as millions of homes.The boom is riding on burning huge amounts of planet-warming natural gas, once cast as a transition fuel on the way to a cleaner grid.Not building the projects, however, risks ceding AI dominance to China.Some question if all these gas power plants will be necessary as AI technology rapidly becomes more efficient.“We’ll be shipping more gas than we ever thought,” said Arshad Mansoor, president and CEO of the nonprofit Electric Power Research Institute. “We are even unretiring coal.”Mansoor predicts it will all work out: He and others in the industry foresee the crushing demand leading to swift breakthroughs in clean energy innovation and deployment. That could include futuristic fusion power, they said, or more conventional technologies that capture natural gas emissions.But some are more skeptical. The independent monitor charged with keeping tabs on the PJM power grid — which serves 65 million customers in the eastern U.S. — is warning that it can’t handle more data centers. It urged federal regulators to indefinitely block more data centers on its grid to protect existing customers.Even in cities yearning to become the next data center hub — with unions welcoming the burst of construction jobs and elected officials offering lucrative tax packages — some apprehension remains.“It’s going to be new to everybody,” said Steffee, of the International Brotherhood of Boilermakers. “We all have to figure out how to start transitioning into this and what the ripple effects will be.”Homer City offers a glimpse of what is coming nationwide.In the Texas Panhandle, the company Fermi America broke ground this year on what it says will be a 5,800-acre complex of gas plants and giant nuclear reactors that would ultimately feed up to 18 million square feet of on-site data centers. It would dwarf Homer City in energy use.Tech companies are planning data ‘campuses’ that would dwarf existing centersIn Cheyenne, Wyoming, developers are aiming to generate 10 gigawatts of electricity for on-site data centers. That’s enough energy to power every house in Wyoming 20 times over. In rural Louisiana, Meta is building a $30 billion cluster of data center buildings that will stretch nearly the length and width of Manhattan.Such facilities will create a major climate challenge. By the mid 2030s, forecasts show the world’s data centers could drive as much carbon pollution as the New York, Chicago and Houston metro areas combined.Check our workDrone video of the Homer City power plant post-demolition courtesy of Homer City Redevelopment LLC.

Polar bear DNA changing in response to climate change

A new study has found that polar bear DNA might be evolving to help these creatures adapt to the stresses of our changing climate. The post Polar bear DNA changing in response to climate change first appeared on EarthSky.

According to new research, polar bear DNA might be changing to help these creatures adapt to a changing climate. Image via Hans-Jurgen Mager/ Unsplash. EarthSky’s 2026 lunar calendar is available now. Get yours today! Makes a great gift. By Alice Godden, University of East Anglia. Edits by EarthSky. The Arctic Ocean current is at its warmest in the last 125,000 years, and temperatures continue to rise. Due to these warming temperatures, more than 2/3 of polar bears are expected to be extinct by 2050. Total extinction is predicted by the end of this century. But in our new study, my colleagues and I found that the changing climate has been driving changes in polar bear DNA, potentially allowing them to more readily adapt to warmer habitats. Provided these polar bears can source enough food and breeding partners, this suggests they may potentially survive these new challenging climates. Polar bear DNA is changing We discovered a strong link between rising temperatures in southeast Greenland and changes in the polar bear genome, which is the entire set of DNA found in an organism. DNA is the instruction book inside every cell, guiding how an organism grows and develops. In processes called transcription and translation, DNA is copied to generate RNA. These are messenger molecules that transmit genetic information. This can lead to the production of proteins, and copies of transposons, also known as “jumping genes.” These are mobile pieces of the genome that can move around and influence how other genes work. Different regions, different genomes Our research revealed big differences in the temperatures in the northeast of Greenland compared with the southeast. We used publicly available polar bear genetic data from a research group at the University of Washington, U.S., to support our study. This dataset was generated from blood samples collected from polar bears in both northern and south-eastern Greenland. Our work built on a Washington University study which discovered that this southeastern population of Greenland polar bears was genetically different to the north-eastern population. Southeastern bears had migrated from the north and became isolated and separate approximately 200 years ago, it found. Researchers from Washington had extracted RNA – the genetic messenger molecules – from polar bear blood samples and sequenced it. We used this sequencing to look at RNA expression – essentially showing which genes are active – in relation to the climate. This gave us a detailed picture of gene activity, including the behavior of the “jumping genes,” or transposons. Temperatures in Greenland have been closely monitored and recorded by the Danish Meteorological Institute. So we linked this climate data with the RNA data to explore how environmental changes may be influencing polar bear biology. Polar bears face challenging conditions thanks to climate change. But they might be responding to this challenge at a genetic level. Image via Dick Val Beck/ Polar Bears International. Impacts of temperature change We found that temperatures in the southeast were significantly warmer and fluctuated more than in the northeast. This creates habitat changes and challenges for the polar bears living in these regions. In the southeast of Greenland, the edge of the ice sheet – which spans 80% of Greenland – is rapidly receding. That means vast ice and habitat loss. The loss of ice is a substantial problem for the polar bears. That’s because it reduces the availability of hunting platforms to catch seals, leading to isolation and food scarcity. EarthSky’s Will Triggs spoke to Alysa McCall of Polar Bears International on Arctic Sea Ice day – July 15, 2025 – to hear about how the decline in arctic sea ice is affecting polar bears and beluga whales. How climate is changing polar bear DNA Over time, it’s not unusual for an organism’s DNA sequence to slowly change and evolve. But environmental stress, such as a warmer climate, can accelerate this process. Transposons are like genetic puzzle pieces that can rearrange themselves, sometimes helping animals adapt to new environments. They come in many different families and have slightly different behaviors, but in essence are all mobile fragments that can reinsert randomly anywhere in the genome. Approximately 38.1% of the polar bear genome is made up of transposons. For humans that figure is 45%, and plant genomes can be over 70% transposons. There are small protective molecules called piwi-interacting RNAs (piRNAs) that can silence the activity of transposons. But when an environmental stress is too strong, these protective piRNAs cannot keep up with the invasive actions of transposons. We found that the warmer southeast climate led to a mass mobilization of these transposons across the polar bear genome, changing its sequence. We also found that these transposon sequences appeared younger and more abundant in the southeastern bears. And over 1,500 of these sequences were upregulated, meaning gene activity was increased. That points to recent genetic changes that may help bears adapt to rising temperatures. What exactly is changing in polar bear DNA? Some of these elements overlap with genes linked to stress responses and metabolism, hinting at a possible role in coping with climate change. By studying these jumping genes, we uncovered how the polar bear genome adapts and responds in the shorter term to environmental stress and warmer climates. Our research found that some genes linked to heat stress, aging and metabolism are behaving differently in the southeast population of polar bears. This suggests they might be adjusting to their warmer conditions. Additionally, we found active jumping genes in parts of the genome that are involved in areas tied to fat processing, which is important when food is scarce. Considering that northern populations eat mainly fatty seals, this could mean that polar bears in the southeast are slowly adapting to eating the rougher plant-based diets that can be found in the warmer regions. Overall, climate change is reshaping polar bear habitats, leading to genetic changes. Bears of southeastern Greenland are evolving to survive these new terrains and diets. Future research could include other polar bear populations living in challenging climates. Understanding these genetic changes helps researchers see how polar bears might survive in a warming world, and which populations are most at risk.

Park Service orders changes to staff ratings, a move experts call illegal

Lower performance ratings could be used as a factor in layoff decisions and will demoralize staff, advocates say.

A top National Park Service official has instructed park superintendents to limit the number of staff who get top marks in performance reviews, according to three people familiar with the matter, a move that experts say violates federal code and could make it easier to lay off staff.Parks leadership generally evaluate individual employees annually on a five-point scale, with a three rating given to those who are successful in achieving their goals, with those exceeding expectations receiving a four and outstanding employees earning a five.Frank Lands, the deputy director of operations for the National Park System, told dozens of park superintendents on a conference call Thursday that “the preponderance of ratings should be 3s,” according to the people familiar, who were not authorized to comment publicly about the internal call.Lands said that roughly one to five percent of people should receive an outstanding rating and confirmed several times that about 80 percent should receive 3s, the people familiar said.Follow Climate & environmentThe Interior Department, which oversees the National Park Service, said in a statement Friday that “there is no percentage cap” on certain performance ratings.“We are working to normalize ratings across the agency,” the statement said. “The goal of this effort is to ensure fair, consistent performance evaluations across all of our parks and programs.”Though many employers in corporate American often instruct managers to classify a majority of employee reviews in the middle tier, the Parks Service has commonly given higher ratings to a greater proportion of employees.Performance ratings are also taken into account when determining which employees are laid off first if the agency were to go ahead with “reduction in force” layoffs, as many other departments have done this year.The order appears to violate the Code of Federal Regulations, said Tim Whitehouse, a lawyer and executive director of the nonprofit advocacy group Public Employees for Environmental Responsibility. The code states that the government cannot require a “forced distribution” of ratings for federal employees.“Employees are supposed to be evaluated based upon their performance, not upon a predetermined rating that doesn’t reflect how they actually performed,” he said.The Trump administration has reduced the number of parks staff this year by about 4,000 people, or roughly a quarter, according to an analysis by the National Parks Conservation Association, an advocacy group. Parks advocates say the administration is deliberately seeking to demoralize staff and failing to recognize the additional work they now have to do, given the exodus of employees through voluntary resignations and early retirements.Rep. Jared Huffman (D-California) said the move would artificially depress employee ratings:“You can’t square that with the legal requirements of the current regulations about how performance reviews are supposed to work.”Some details of the directive were first reported by E&E News.Park superintendents on the conference call objected to the order. Some questioned the fairness to employees whose work merited a better rating at a time when many staff are working harder to make up for the thousands of vacancies.“I need leaders who lead in adversity. And if you can’t do that, just let me know. I’ll do my best to find somebody that can,” Lands said in response, the people familiar with the call said.One superintendent who was on the call, who spoke on the condition of anonymity to avoid retaliation, said in an interview that Lands’ statement “was meant to be a threat.”The superintendent said they were faced with disobeying the order and potentially being fired or illegally changing employees’ evaluations.“If we change these ratings to meet the quota and violated federal law, are we subject to removal because we violated federal law and the oath we took to protect the Constitution?” the superintendent said.Myron Ebell, a board member of the American Lands Council, an advocacy group supporting the transfer of federal lands to states and counties, defended the administration’s move.“It’s exactly the same thing as grade inflation at universities. Think about it. Not everybody can be smarter than average. If everyone is doing great, that’s average,” he said.Theresa Pierno, president and CEO of the National Parks Conservation Association, said in a statement that the policy could make it easier to lay off staff, after the administration already decimated the ranks of the parks service.“After the National Park Service was decimated by mass firings and pressured staff buyouts, park rangers have been working the equivalent of second, third, or even fourth jobs protecting parks,” Pierno said.“Guidance like this could very well be setting up their staff to be cannon fodder during the next round of mass firings. This would be an unconscionable move,” she added.
