Observations of SN 2023ixf in 2023 led to surprising findings regarding cosmic ray production by supernovae, with potential implications for understanding cosmic ray origins and acceleration mechanisms.

In 2023, a nearby supernova offered astrophysicists an excellent opportunity to test ideas about how these types of explosions boost particles, called cosmic rays, to near light-speed. But surprisingly, NASA’s Fermi Gamma-ray Space Telescope detected none of the high-energy gamma-ray light those particles should produce.

On May 18, 2023, a supernova erupted in the nearby Pinwheel galaxy (Messier 101), located about 22 million light-years away in the constellation Ursa Major. The event, named SN 2023ixf, is the most luminous nearby supernova discovered since Fermi launched in 2008.

Cosmic Rays and Their Origins

Trillions of trillions of cosmic rays collide with Earth’s atmosphere every day. Roughly 90% of them are hydrogen nuclei – or protons – and the remainder are electrons or the nuclei of heavier elements.

Scientists have been investigating cosmic ray origins since the early 1900s, but the particles can’t be traced back to their sources. Because they’re electrically charged, cosmic rays change course as they travel to Earth thanks to magnetic fields they encounter.

“Gamma rays, however, travel directly to us,” said Elizabeth Hays, the Fermi project scientist at NASA’s Goddard Space Flight Center in Greenbelt, Maryland. “Cosmic rays produce gamma rays when they interact with matter in their environment.

Supernovae As Cosmic Ray Accelerators

Astrophysicists have long suspected supernovae of being top cosmic ray contributors.

These explosions occur when a star at least eight times the Sun’s mass runs out of fuel. The core collapses and then rebounds, propelling a shock wave outward through the star. The shock wave accelerates particles, creating cosmic rays. When cosmic rays collide with other matter and light surrounding the star, they generate gamma rays.

Supernovae greatly impact a galaxy’s interstellar environment. Their blast waves and expanding cloud of debris may persist for more than 50,000 years. In 2013, Fermi measurements showed that supernova remnants in our own Milky Way galaxy were accelerating cosmic rays, which generated gamma-ray light when they struck interstellar matter. But astronomers say the remnants aren’t producing enough high-energy particles to match scientists’ measurements on Earth.

One theory proposes that supernovae may accelerate the most energetic cosmic rays in our galaxy in the first few days and weeks after the initial explosion.

But supernovae are rare, occurring only a few times a century in a galaxy like the Milky Way. Out to distances of around 32 million light-years, a supernova occurs, on average, just once a year.

After a month of observations, starting when visible light telescopes first saw SN 2023ixf, Fermi had not detected gamma rays.

Challenges and Future Research

“Unfortunately, seeing no gamma rays doesn’t mean there are no cosmic rays,” said co-author Matthieu Renaud, an astrophysicist at the Montpellier Universe and Particles Laboratory, part of the National Center for Scientific Research in France. “We have to go through all the underlying hypotheses regarding acceleration mechanisms and environmental conditions in order to convert the absence of gamma rays into an upper limit for cosmic ray production.”

The researchers propose a few scenarios that may have affected Fermi’s ability to see gamma rays from the event, like the way the explosion distributed debris and the density of material surrounding the star.

Fermi’s observations provide the first opportunity to study conditions right after the supernova explosion. Additional observations of SN 2023ixf at other wavelengths, new simulations and models based on this event, and future studies of other young supernovae will help astronomers home in on the mysterious sources of the universe’s cosmic rays.

The Environmental and Human Rights Costs of China’s Clean Energy Investments Abroad

Chinese companies have pledged hundreds of billions of dollars in clean energy manufacturing investments overseas, but the projects are having significant social, environmental, and human rights impacts.

This story originally appeared on Inside Climate News as part of its Planet China series and is part of the Climate Desk collaboration.The audience sat patiently through the presentations about the cluster of battery factories going up nearby. They listened to descriptions of the hazardous chemicals the plants will use, their huge water withdrawals and energy demands.WIRED's Guide to How the Universe WorksYour weekly roundup of the best stories on health care, the climate crisis, new scientific discoveries, and more. When it came time for questions, people began shifting in their chairs and standing up, making the cramped room feel even smaller.What if the chemicals leak, one woman asked. What’s in it for the politicians in their “velvet chairs,” another demanded. A third warned it would be just like the Soviet era, when iron and steel plants left a polluted legacy.Then a woman began to tear up as she told the 50 or so people who had gathered in a community center on a cold, dark evening that the factories’ smokestacks and hazardous materials were about a mile from her daughter’s kindergarten.“Please stand up for yourselves,” she said, urging the audience to spread the word.The Chinese battery giant Contemporary Amperex Technology Co., or CATL, is nearing completion on what could be one of Europe’s largest electric vehicle battery factories. The industrial park where it is located, outside Debrecen, Hungary’s second-largest city, also hosts several other manufacturers of battery parts and supplies. At least two of those are owned by Chinese companies, one by a South Korean firm. Another Chinese-owned battery factory is being built on the other side of the city.The surge of construction is part of a nationwide frenzy, prompted by Prime Minister Viktor Orbán’s goal to make Hungary a leading battery manufacturer. To reach this target, Orbán has looked primarily to Beijing. Chinese companies have announced or built at least 18 EV and battery-related projects in Hungary so far, $17 billion in pledged investments, according to data compiled by the Net Zero Industrial Policy Lab at Johns Hopkins University.While the factories could position Hungary in the center of Europe’s transition off fossil fuels, they have prompted a backlash from residents worried about their impacts on public health and the environment.“Everyone will get their fair share of this stew,” said Éva Kozma, who leads the Mikepércs Mothers for the Environment Association, a citizen activist group that hosted the event. Kozma helped form the group after CATL announced its plans in 2022 and has since been highlighting the risks posed by battery development, identifying pollution events and scrutinizing the factories’ permits.

Inside the North Carolina GOP’s decade-long push to seize power from state’s Democratic governors

GOP lawmakers have passed law after law stripping powers from Democratic governors

In November 2024, Democrat Josh Stein scored an emphatic victory in the race to become North Carolina’s governor, drubbing his Republican opponent by almost 15 percentage points. His honeymoon didn’t last long, however. Two weeks after his win, the North Carolina legislature’s Republican supermajority fast-tracked a bill that would transform the balance of power in the state. Its authors portrayed the 131-page proposal, released publicly only an hour before debate began, as a disaster relief measure for victims of Hurricane Helene. But much of it stripped powers from the state’s governor, taking away authority over everything from the highway patrol to the utilities commission. Most importantly, the bill eliminated the governor’s control over appointments to the state elections board, which sets voting rules and settles disputes in the swing state’s often close elections. Ignoring protesters who labeled the bill a “legislative coup,” Republicans in the General Assembly easily outvoted Democrats, then overrode the outgoing Democratic governor’s veto. The maneuver culminated a nearly decade-long effort by Republican legislators, who have pushed through law after law shrinking the powers of North Carolina’s chief executive — always a Democrat during that time frame — as well as the portfolios of other executive branch officials who are Democrats. Over that period, lawmakers have attempted to transfer control or partial control of at least 29 boards, entities or important executive powers. In most cases, they succeeded. As a result, Republicans now hold increased sway not only over North Carolina’s election board, but also over its schools, building codes, environmental regulations, coastal development, wildlife management, utilities, cabinet appointments and more. All had previously been under control of the governor. “This is not what people voted for,” said Derek Clinger, a senior counsel at the State Democracy Research Initiative, an institute at the University of Wisconsin Law School, who has studied the events in North Carolina. Stein, as well as all of North Carolina’s living former governors — Republicans and Democrats alike — have blasted the legislature’s erosion of gubernatorial authority as a violation of the state’s constitutionally enshrined separation of powers. “You should not be able to make the laws and then control who enforces them — just ask any fourth grader about the three branches of government,” Stein said in a statement to ProPublica. Lawmakers’ actions “throw the will of the voters into the trash can,” he added. Initially, governors had some success using separation-of-powers arguments in lawsuits filed to challenge efforts to strip their powers. Even majority-Republican courts ruled in their favor, declaring laws that shifted authority directly from the governor to the legislature were unconstitutional. More recently, though, legislators have found a loophole, writing laws that move traditional gubernatorial powers to elected executive branch officials who are Republicans. Since 2023, when the GOP won majorities on the state’s appellate courts, judges have increasingly rejected lawsuits aimed at blocking such legislation. The North Carolina GOP’s effort to rein in executive power at the state level stands in sharp contrast to the Trump administration’s efforts to expand such power federally. Before the Supreme Court, for example, the administration has argued for a “unitary executive” theory that would allow the president near-total control over personnel. North Carolina Republican legislative leaders didn’t respond to interview requests or detailed emailed questions from ProPublica about the power shifts. In the past, Republicans have defended whittling down Democratic governors’ authority by pointing to similarly partisan moves by Democrats decades ago, though these were on a much smaller scale. Current and former lawmakers also say the power shifts reflect the vision of North Carolina’s founders, who deliberately made the state’s governor weak and its legislature strong to prevent abuses suffered under British rule. “It’s never been co-equal, never will be, never intended to be,” said Paul Stam, who was the lame-duck Republican speaker pro tempore of the House when the General Assembly began its push to weaken the governor in 2016. Republicans also dispute the notion that voters oppose reducing governors’ authorities. “The people voted for a strong Republican majority in the legislature,” Sam Hayes, the former general counsel for North Carolina’s speaker of the House, said in an interview. “That role can involve reassigning the powers of the executive branch.” After lawmakers took away the governor’s power to appoint the election board’s members, Hayes became its director. The board’s new Republican majority has handed control over North Carolina’s county election boards to conservatives, some of whom have moved to eliminate early voting sites favored by Democrats. In recent years, states including Wisconsin, Michigan and Kentucky have waged similar battles over separation of powers. In almost all cases, Republican-dominated legislatures have stripped powers from Democrats elected to statewide offices. Still, North Carolina’s example has been particularly notable, critics say. According to a scholarly review by Clinger, the General Assembly’s power grabs in 2016 and 2024 are the most expansive in recent American history. Collectively, lawmakers have brought the powers of the state’s chief executive to a low ebb, said Christopher Cooper, a political scientist at Western Carolina University. In 2010, the textbook “Politics in the American States” ranked the institutional powers of North Carolina’s governor the third-weakest in the nation. By 2024, they ranked dead last. “Soon,” Cooper said of the legislature, “they’re not going to have anything left to take.” When the battles over the election board began in 2016, the joke among Republican lawmakers was that to get things done on elections policy, “you either need the Northern Hammer or the Sweet Southern Stammer.” The Northern Hammer was Bob Rucho, a famously blunt senator originally from Massachusetts. The Sweet Southern Stammer was David Lewis, a genial Republican House member from rural North Carolina with a speech impediment and an uncommon mastery of election law. The self-deprecating Lewis, a farmer and tractor salesman by trade, had helped design the gerrymandering strategies that, starting in 2010, handed Republicans long-term control of the legislature even in election cycles when Democrats won a majority of statewide offices. The importance of controlling the election board — and the potential disastrousness of not controlling it — was clear in the 2016 gubernatorial race, a close contest between Republican Gov. Pat McCrory and his Democratic challenger, Roy Cooper. The board makes decisions that can affect election outcomes in myriad ways, such as deciding where and for how long early voting takes place. It picks the state’s election director and members of county election boards, which maintain voter registration lists and operate voting sites. It arbitrates postelection challenges from losing candidates. As governors historically had, McCrory had appointed the five board members who oversaw the 2016 race, choosing three from his party and two from the opposing party as state law directed. But the panel and its professional staff still operated with considerable independence. After McCrory challenged his 10,000-vote loss to Cooper, alleging widespread voter fraud, the board — led by McCrory’s picks — voted against his protests, effectively ending the race. When Republican legislators launched their first effort to seize control of the board soon after, senior staffers figured it was payback for not helping McCrory. “I viewed it as retaliation for the board not having played a partisan enough role,” said Katelyn Love, who was then an attorney for the board and went on to become its general counsel. Lewis, who left the legislature in 2020, said he and other lawmakers were convinced that once appointment power passed to Cooper, he’d “stack the board” against Republicans. “In certain parts of the state,” he said, “elections really do come down to two or three votes, or a small percentage of votes, and we had no confidence” that Cooper’s appointees “would just treat us fairly.” Republican legislative leaders called a special session, proposing multiple bills that redirected powers from the governor, often to the legislature itself. “We said, ‘You know what: We’re the legislature and we decide who appoints who,’” Lewis recalled. “Instead of letting Roy do it, why don’t we put folks in place that kind of support the way we see things?” Lawmakers targeted not only the elections board, but also Cooper’s ability to hire and fire more than 1,000 political appointees in state government and to choose members of the state’s Industrial Commission, which handles matters such as worker safety claims. They took aim at some positions in part because they came with big paychecks, Lewis acknowledged; a seat on the Industrial Commission pays more than $160,000, for example. “The truth is, a lot of the importance of some of these positions is who gets to appoint whose friends to the board,” Lewis said. “It’s kind of considered a plum job.” The election board measure was framed as making oversight more bipartisan. Indeed, it increased the number of board members to eight and required even numbers of Republican and Democratic appointees. But the governor controlled only four of those seats. The legislature appointed the other four. Also, in even-numbered years — those when federal elections are held — the law required the board’s chair to be “a member of the political party with the second-highest number of registered affiliates.” At the time, that meant a Republican. Since the chair shaped what matters were taken up and had other bureaucratic influence, this gave the party an edge. Lewis insisted the restructured board was designed to even the scales — between the parties and between the governor and the legislature. “If one side can block the other, then bad things don’t happen,” he said. “And if both sides can work together, you can get a more positive resolution.” Less than two weeks after McCrory conceded, the legislature quickly forced through the changes, despite protests so intense they led to numerous arrests. Cooper quickly filed a court challenge, arguing that the law violated the state’s constitution and stymied his ability to enact his policies. The separation of powers is explicitly enshrined in North Carolina’s constitution, which declares, “The legislative, executive, and supreme judicial powers of the State government shall be forever separate and distinct from each other.” Democrats also made the case that the new, evenly split election board was intended to produce gridlock that effectively favored Republicans, keeping in place the election director chosen by McCrory’s board and blocking steps that required majority approval, such as establishing early voting sites. In March 2017, a trial court struck down most of the legislative changes, including those affecting the elections board, ruling they illegally robbed the governor of executive authority. Lewis and other Republican leaders went back to the drawing board. Small groups of election specialists and legislative aides met early in the morning or late at night, surviving on food from Bojangles, the much-loved fried-chicken-and-biscuits chain. They sketched out priorities and drafted legislative language on whiteboards, then waited for the opportune moment to introduce a bill. According to Lewis and other Republicans, they were determined to find a winning formula, no matter how many shots it took. “We felt like we had every right to do that because the constitution invested the legislature with defining the responsibilities” of the governor, Lewis said. A month after the trial court rejected lawmakers’ first stab at breaking the governor’s grip on the elections board, the legislature tried again. It passed another law that altered the board in much the same ways as the first, expanding it to eight members, for example. But this time, instead of giving the legislature half the appointments, the law directed the governor to make all of them — from lists provided by the chairs of the state’s Democratic and Republican parties. Cooper, calling the measure the “the same unconstitutional legislation in another package,” swiftly filed another legal challenge. For almost a year, as the case wound through the courts, he refused to make appointments under the proposed rules. The board’s professional staff kept up with administrative tasks but struggled to find workarounds for responsibilities handled by board members. They went to court on multiple occasions to get judges to rule on election protests and challenges in the board’s absence. “It was very disruptive and chaotic, and a drain on the agency’s limited resources,” Love said. In January 2018, the state Supreme Court struck down the legislature’s second attempt at taking over the elections board. The third came two months later, when lawmakers passed a bill that resurrected many elements of the previous one, but with a few new tweaks. In this version, the governor chose the board’s eight members — four Republicans and four Democrats — from lists submitted by each party, plus an additional tie-breaking member, unaffiliated with either party, from nominees provided by the new board. Despite these differences, the outcome was much the same: another lawsuit from Cooper and, eventually, another loss in court. Republican legislators realized they were likely to lose the case, so they also decided to try a strategy that took the issue out of the hands of the court system, Lewis said. They put a constitutional amendment on the November 2018 ballot that proposed removing the governor’s power to choose election board members and giving that authority to the legislature. “You put your idea out for the people,” Lewis said. If “they vote for it, then it’s no longer unconstitutional.” Of the six constitutional changes on the ballot that year, the election board proposal and one other — an amendment altering who picked judges to fill empty or added court seats — targeted traditional gubernatorial powers. The measures were hotly contested, attracting about $18 million in spending by groups for and against them. Lewis said that Republican internal polling showed clear support for the amendments, but the final tallies showed a notable divide: Voters passed four of the measures but rejected the two that stripped powers from the governor by roughly 2 to 1. At the end of 2018, Republicans temporarily waved the white flag, passing a law that returned the governor’s control over the election board. In 2020, Lewis relinquished his longtime role as the House’s election policy point man after pleading guilty to charges related to using campaign funds for personal expenses, including rent. He then resigned. Today, Lewis sells cars in a small town on North Carolina’s swampy southeastern coast and does occasional political consulting. Looking back, he still believes he did the right thing. “I was following the will of the voters that gave us the majority in the legislature to do these things.” Over the next few years, the elections board made one critical decision after another in close or disputed elections, underscoring its importance. In one instance, it called a new election in a congressional race tainted by an illegal scheme to fraudulently collect and fill out mail-in ballots. Republican legislative leaders bided their time, waiting for another opportunity to launch a takeover. Karen Brinson Bell, chosen as the state’s election director in May 2019 by Cooper’s appointees, said lawmakers never let her forget the tenuousness of her position. “I knew from the day I started that my days were numbered,” she said. “I was never naive to the fact that there would likely be other attempts to change the makeup of the board.” Bell said that at a December 2022 meeting held by the National Conference of State Legislatures in West Virginia, Warren Daniel, a Senate Republican who worked on election matters, told her that he and his colleagues planned to take over the board and to reduce early voting. (Daniel didn’t respond to ProPublica’s questions about the incident.) In October 2023, the moment Bell had long expected finally arrived. The legislature’s Republican supermajority introduced a new bill to remake the election board. It shifted control over appointments to the General Assembly’s majority and minority leaders and put some of the board’s administrative functions under the secretary of state. On decisions where the board’s four Republicans and four Democrats deadlocked, the law gave Republicans a decided advantage. If members couldn’t agree on an executive director, for example, the legislature’s majority leaders would choose one. If the board couldn’t agree on a plan for expanded early voting (championed by Democrats), then each county would have just one early voting site, the minimum required by law. The measure was similar to its predecessors, but the courts that would decide its legality were vastly different. Since the demise of the previous election board law, Republicans had won 14 appellate court races in a row and held majorities on the state’s higher courts. The Supreme Court’s chief justice, Paul Newby, had made it clear he saw no legal impediment to whittling down the governor’s portfolio, writing a sharp dissent to a ruling that struck down an earlier attempt to limit gubernatorial power. In February 2024, a trial court issued a decision that reframed the debate over the constitutionality of gubernatorial power transfers. This time, the case didn’t involve the election board. It dealt instead with a law that used a variety of mechanisms to strip away Gov. Roy Cooper’s control over seven other entities that managed everything from coastal resources to building codes. A three-judge panel found three of the seven transfer schemes legal because power passed from the governor to another elected executive branch member. “While the Governor is the chief executive, other elected officers who are members of the Council of State are also vested with executive power,” the judges wrote. Michael Gerhardt, a constitutional law professor at the University of North Carolina at Chapel Hill who studies issues related to separation of powers, was aghast, saying the decision reflected partisanship rather than sound legal analysis. The court was “ignoring the fact that the governor was actually elected” and “allowing the state legislature to transfer some of his authority to Republican officials,” he said. Mitch Kokai, a senior political analyst at the conservative John Locke Foundation, argued the panel’s finding was consistent with North Carolina’s history of splitting executive power among multiple executive branch officials. He dismissed Gerhardt’s comments as partisan “sour grapes.” “The Democrats are losing, and they don’t like the fact that the Republicans are winning, so they’re casting doubt on what the conservative courts are saying,” he said. The ruling didn’t affect the October 2023 election board measure, which hadn’t been implemented, blocked by a separate trial court decision. But after Stein’s double-digit win in the 2024 governor’s race, Republican lawmakers again used a legislative session ostensibly about hurricane relief to introduce a new, superseding measure that would finally put the election board under their party’s control. It used a power transfer strategy similar to the ones that had won court approval the previous February, placing election board appointments in the hands of Dave Boliek, a Republican newly elected to the executive branch office of state auditor. Boliek could choose three of the board’s five members from his own party, giving Republicans their long-sought majority. No other state auditor in America manages elections and Boliek had no experience doing so, but he expressed enthusiasm about taking on the job. “Governor Josh Stein doesn’t have any experience supervising elections either,” Boliek told ProPublica in an email exchange. “Leading a public office requires a willingness to learn and serve — and I’m a quick study.” In the same law, legislators also redirected Stein’s authority to make appointments to an array of other boards and entities and stripped powers from other newly elected Democrats, including the lieutenant governor, attorney general and superintendent of public instruction. Stein sued to prevent the changes from taking effect, but in May, the Newby-led Supreme Court declined to block Boliek’s takeover of the election board. Although litigation continues, he has started transforming election oversight, both statewide and locally, in ways that would be hard to undo. Some of Boliek’s board members have long histories in Republican politics and efforts to tilt state elections in the party’s favor. The new chair, Francis De Luca, had led a conservative institute that sued to contest McCrory’s loss in the 2016 race for governor. (De Luca didn’t respond to ProPublica’s request for comment.) Another new Republican member was Rucho, the so-called Northern Hammer who’d worked on election policy with Lewis. The new board will be fair, he promised. “My goal is to level the playing field so that everyone is playing by the same rules,” he said. Bell’s replacement as election director, Hayes, has overhauled the board’s 60-member staff, though historically it’s been nonpartisan and largely remained when new leadership took over. Since Hayes took charge, at least nine staffers have left or been placed on leave, according to interviews and published reports. At the same time, the board has added seven new political appointees, many of whom have close ties to Republican politicians. “It’s a nonpartisan shop shifting to a partisan shop,” said one staff member who asked not to be identified, fearing retaliation. Hayes insisted the board remains nonpartisan and described the changes in staff as “nothing out of the ordinary.” He described his goals as “repairing relationships with the General Assembly” and working to “honor the letter and spirit of the law.” “If we do that,” he said, “I believe that we will rebuild trust in elections here.” Under Hayes’ leadership, the board also moved swiftly to settle a lawsuit filed against it earlier this year by the U.S. Justice Department, agreeing to require tens of thousands of voters to provide missing registration information or risk not having their ballots count in state races, voter advocacy groups say. Bell had opposed taking such steps. Hayes said he settled the suit with the “intent of honoring federal law” and to clean up the state’s voter rolls, which Republicans argue have been badly mismanaged. The new leadership has also taken steps that could limit early voting locations in the state, especially those in Democratic strongholds. Boliek hired longtime Republican operative Dallas Woodhouse, who has advocated for restricting early voting, to fill a newly created role partly focused on early voting. In October, Woodhouse emailed Republican board chairs directing them to consider moving polling sites out of urban areas, where there are more Democrats, to “areas that are outside of urban cores,” where Republicans tend to hold the majority. So far, conservative majorities in at least eight counties have moved to limit early voting sites or weekend hours sought by Democrats. At least two have rejected sites near universities, including a site near a historically Black college. In an interview, Boliek told ProPublica there was no plan to reduce early voting sites in areas that lean Democratic. He later explained in an email that Woodhouse “simply answered inquiries from board chairs.” Hayes communicates with Cleta Mitchell, a lawyer who tried to help Trump overturn the 2020 election, and Woodhouse regularly attends video calls held by the North Carolina chapter of Mitchell’s national organization, the Election Integrity Network. Boliek said Woodhouse talks to a variety of organizations from across the political spectrum, adding,“I don’t think people should be concerned.” He said the board was dedicated to making “it easy to vote and hard to cheat in North Carolina.” Hayes said Mitchell and other network leaders aren’t “receiving special access to me or treatment from this office” and that he talks to people on both sides of the aisle. All told, Republican legislators have successfully transferred power over 17 of the 29 boards, entities and important executive prerogatives they’ve targeted since 2016, a ProPublica review showed. In addition to the election board, the governor has lost control or partial control over a dozen entities, including the state’s Environmental Management Commission and its Utilities Commission. Stein told ProPublica that state residents have suffered, in the form of weakened environmental protections and rising energy costs. Rucho, the Northern Hammer, argues the power transfers have actually improved life in the state. “You have to change the way the system works, if the system is not working,” he said. “This was a real good remedy to make these boards work on behalf of the people.” Longtime observers say they have deepening concerns about the erosion of the separation of powers in North Carolina. Bob Orr, a former Republican state Supreme Court justice, said that if power grabs by Republican legislators continue to be upheld by the state’s Republican-majority courts, it will threaten democracy in the state. “Really, what can people do?” said Orr, who left the Republican Party because of how it changed under Trump. “A legislature that is literally unchecked with gerrymandered districts and a presumption of constitutionality for everything they do in the courts — that is a danger to democracy because they can change the system regardless of the will of the people.” The post Inside the North Carolina GOP’s decade-long push to seize power from state’s Democratic governors appeared first on Salon.com.

The Bad River Band is suing to protect its wild rice from an oil pipeline

The lawsuit targets a federal permit for Enbridge’s Line 5, which the tribe says puts wetlands, rivers, and treaty-protected resources at risk.

Around August of each year, when temperatures swell in the Great Lakes region, wild rice — or manoomin in the Ojibwe language — begins to flower. Rice stalks can grow as high as 10 feet in the shallow waters, and to harvest, sticks and poles are used to knock seeds loose into boats or canoes. The harvest is critical each year to the Ojibwe. But those ricing waters are under threat as the Canadian oil transport company Enbridge looks to reroute its controversial pipeline, Line 5, through prime harvesting areas. Now, the Bad River Band of Lake Superior Chippewa, one of six Ojibwe bands in northern Wisconsin, has filed a lawsuit against the United States Army Corps of Engineers, or USACE, to stop construction. “For hundreds of years, and to this day, the Band’s ancestors and members have lived, hunted, fished, trapped, gathered, and engaged in traditional activities in the wetlands and waters to be crossed by the project,” the lawsuit says. In October, USACE granted Enbridge a permit to build a 41-mile addition to Line 5 in order to circumvent the Bad River reservation, but Earthjustice, a nonprofit litigation organization representing the tribe, argues the permit failed to comply with the National Environmental Policy Act and the Clean Water Act. Earthjustice says the pipeline will cross waterways that flow onto the Bad River Reservation and leaks would threaten the watershed and ecosystem, needed for wild rice harvesting and fishing. After the largest inland oil spill from Enbridge’s pipelines in the U.S. in 2010 — flooding more than a million gallons into the Kalamazoo River in Michigan — the largest spill in Wisconsin’s history happened last year. The company reported around 69,000 gallons of oil spilled onto the ground near a rural town in the south of the state. Initially, the spill was reported as two gallons; it was a month before the public officially knew the spill’s size.  Line 5 has operated for more than 70 years and has become a major legal battle for multiple tribal nations in the Great Lakes region. During the 1950s, for the Lakehead Pipeline, the company fitted 12 miles of pipeline across the 124,655-acre reservation to transport oil from western Canada to eastern Canada. Despite the treaty of 1854 that established permanent reservation territory and the treaty of 1842, cementing the right to hunt, gather, and fish, the company did not initiate talks with the tribe on pipeline siting.  In 2019, the Bad River Band sued Enbridge to cease operations on their land, ordering the company to remove its pipeline from the reservation. In 2023, a federal judge backed the nation, ruling that the company had three years to remove its property from the reservation and pay a $5.1 million fine for trespassing. The tribe said the proposed 41-mile addition would impact at least 70 different waterways as Enbridge will need to use explosives and horizontal drilling to build the extension. “Oil and gas contribute to pollution in a number of ways, and the Trump administration is focused on energy dominance,” said Gussie Lord, a member of the Oneida Nation and an attorney at Earthjustice. “It’s cut out renewable energy from the equation to the extent it can, and it just really feels like a backward-looking playbook to me.”  Last year, under the Biden administration, the USACE conducted an environmental assessment on the proposed route rather than an environmental impact study. Environmental assessments allow for faster review, while environmental impact studies are more thorough and require more time and resources to evaluate a project’s impact. They also allow for consultation with tribal nations to determine if a project violates treaty rights, cultural resources, or access to clean water. In neighboring Michigan, Enbridge is also up against tribal nations and state officials in order to operate a nearly 5-mile pipeline segment under the Great Lakes to replace a 72-year-old section of Line 5. This month, a federal judge blocked Michigan from enforcing an order to shut the pipeline down, ruling that pipeline safety is a matter of federal responsibility, not states. In March, the Army Corps fast-tracked a permit for the segment under the Trump administration’s energy emergency declaration, allowing the agency to bypass regulatory laws, like the National Environmental Policy Act. Shortly after, seven tribal nations withdrew from discussions, citing the federal government’s failure to engage with tribal governments. Currently, the initial permit hasn’t been signed or finalized by the USACE. “Until the permit is signed, USACE has not engaged in a judicially reviewable final agency action,” a spokesperson for Enbridge said. “Enbridge will move to intervene in the lawsuit and defend the USACE’s forthcoming permit decision.” In Wisconsin, the Bad River Band has also initiated litigation against the Wisconsin Department of Natural Resources over its state permitting of Enbridge in August.  Gussie Lord of Earthjustice said litigation is going to be an uphill battle, but adds that the Bad River Band believes it’s their responsibility to protect the area’s watershed and environment. “We need people who are going to be thinking about what makes sense, for the future, not just 10 years from now, but 50 years, 100 years from now,” Lord said.

‘Bonkers': DOI letter halts all five in-progress offshore wind farms

The Interior Department announced Monday it is pausing leases for all five large-scale offshore wind projects under construction in America, citing unspecified issues of national security. Canary Media obtained a copy of a letter notifying one of the affected wind farm developers, providing new details about the…

The Interior Department’s press release about the pause also cites claims not included in the letter to Dominion Energy, including mention of a 2024 Department of Energy study that determined offshore wind turbines could cause radar to ​“miss actual targets” while also noting that ​“wind energy will play a leading role in the nation’s transition to a clean energy economy.” Dominion Energy did not respond to a request for comment.  A spokesperson for Equinor, the partially state-owned Norwegian energy firm that is developing the Empire Wind project off the coast of New York, said, ​“We are evaluating the order and seeking further information from the federal government.”  The Trump administration had previously hit two of the affected projects — Empire Wind and Revolution Wind — with stop-work orders. Both installations were later allowed to proceed, although that construction pause cost Equinor nearly $1 billion. The remaining three projects, Coastal Virginia, Vineyard Wind, and Sunrise Wind, had been spared until now. Several of these projects are more than halfway complete; Revolution Wind is at least 80% finished. Monday’s announcement is not the first time the administration has used national security as an excuse for throwing sand in the gears of offshore wind.  But between 2020 and 2023, the Revolution Wind project endured an extensive regulatory review, including by the Pentagon and Federal Aviation Administration. BOEM approved the project under the condition that all turbines be built to lighting and marking standards that would ensure they’re visible to aircraft at night. No mitigation for radar is mentioned. In August 2023, the U.S. Army Corps of Engineers — a branch of the military — co-signed the authorization of plans for Danish developer Ørsted to build 65 wind turbines for the Revolution Wind project.  “Was the military at the table, represented and consulted with during this stakeholder process? The answer is: very much so,” wind energy veteran Bill White told Canary Media in August. From 2009 to 2015, White represented Massachusetts on a BOEM-led intergovernmental task force focused on the siting of New England offshore wind energy areas.  In February 2024, a Brown University research group examined 441 claims made against offshore wind during the first six months of 2023. They found multiple times ​“military readiness” and ​“radar interference” were mentioned in ways that the researchers found misleading or problematic.  “[S]uggesting that our military is unaware of this issue or has done nothing to address it is completely untrue,” the report concluded.  J. Timmons Roberts, a co-author of the report and a professor of environmental studies and sociology at Brown University, called the administration’s halt to five approved wind farms because of classified national security information ​“bonkers.” “These claims aren’t new and they have been, in the past, shown to be quite baseless,” he said. { if ($event.target.classList.contains('hs-richtext')) { if ($event.target.textContent === '+ more options') { $event.target.remove(); open = true; } } }" >

Dakota Access Pipeline Should Continue Operating, US Army Corps of Engineers Says

HOUSTON, Dec 19 (Reuters) - The ‌U.S. ​Army Corps of ‌Engineers on Friday released a long-anticipated Environmental Impact ​Statement for the Dakota Access Pipeline (DAPL), recommending that operations of the ‍oil pipeline continue with ​some conditions.The EIS, a document required by U.S. law ​to ⁠evaluate the environmental effects of major federal actions, is a win for DAPL operator Energy Transfer and a step closer to the end of a lengthy court battle between the company and ‌nearby Native American tribes, who have been fighting for ​the pipeline's ‌closure.The document recommends the continued ‍operation ⁠of DAPL, on the grounds that safeguards are put in place such as groundwater monitoring, fish tissue residue analyses and water and sediment sampling, as well as the deployment of new leak detection technology.A U.S. court in 2022 ordered the federal government to undertake a more intensive ​EIS of the 1,100-mile (1,800-km) crude pipeline's route as part of the dispute between Energy Transfer and the tribes who have cited risks to water quality as the pipeline runs through Lake Oahe, with the crossing around half a mile north of the Standing Rock Sioux Reservation.The pipeline has continued to operate while the review is being carried out. It is the biggest oil pipeline ​from the Bakken shale oil basin and can transport up to 750,000 barrels of oil per day from North Dakota to Illinois.It is not known whether USACE's ​recommendation will be implemented. (Reporting by Georgina McCartney in Houston; Editing by Paul Simao)Copyright 2025 Thomson Reuters.
