President Donald Trump signed a law Tuesday, April 28, 2026, ending the Boundary Waters mining ban and rolling back federal protections near Minnesota's Boundary Waters Canoe Area Wilderness.

Michigan wildlife officials found five dead bald eagles on Tuesday, April 28, 2026, and have opened a probe into suspected illegal killings, a development reported by Fox News.

A recent air-quality report rated the Twin Cities "F" for particle pollution due to high fine-particle levels in Minnesota. The grade placed the metro at 39th most polluted in the nation for particle pollution, according to the assessment. These particles, often called PM2.5, come from vehicle exhaust, wood burning and industrial emissions and can harm lungs and hearts.

The National Weather Service expanded a red flag warning covering wildfire risk to 54 Minnesota counties on Wednesday. The warning was issued because hot, dry and breezy conditions will raise the risk of fast-moving wildfires across the state. It was in effect until 8 p.m. Wednesday.

The Minnesota Mosquito Control District began mosquito treatments across the Twin Cities this week after a record West Nile year in 2025.

A new study finds humans cause about 65% of wolf deaths in the Upper Midwest. Researchers say this pattern holds even after recent federal law changes aimed at changing wolf protections and management. FOX 9 Minneapolis-St. Paul reported on the study and its conclusion.

The Minnesota Department of Natural Resources recently tightened burning rules, expanding restrictions farther north as wildfire risk grows. The DNR said the move responds to rising fire danger across regions that have become drier and more prone to large wildfires in recent weeks.

A bipartisan bill to bar local elected officials and governments from signing nondisclosure agreements in economic-development negotiations — including data-center deals — stalled in the Minnesota House Judiciary Committee after every Republican on the panel voted against advancing it. Sponsors (two Republicans and two Democrats) and supporters call it a transparency measure, while Judiciary Republicans say it could act as a de facto ban on data centers and argue many NDA-covered agreements are already subject to public-records requests; the bill still appears to have a strong chance in the Senate, but its House prospects are now murky.

Minnesota lawmakers in both the House and Senate are advancing bipartisan bills to fund a formal study of nuclear power, a move supporters openly describe as the first step toward ending the state's 32-year ban on new nuclear plants. The study would weigh the costs, timelines, safety issues and waste-storage implications of adding new reactors as Minnesota phases out coal and natural gas, with backers hoping it could tee up a moratorium repeal as soon as next year. Rep. Spencer Igo (R-Wabana Township) argues that electrification and population growth will leave a major 'gap' in power supply without nuclear, while Rep. Larry Kraft (DFL-St. Louis Park) counters that nuclear has only gotten more expensive and slower to build over time. Sen. Nick Frentz (DFL-North Mankato), who authored the state's 2040 carbon-free law, says nuclear must be evaluated alongside cheaper wind, solar and possible geothermal, and stresses that any new plants would still be at least eight years away and require local community input. The Prairie Island Indian Community, which lives next to one of the nation's closest nuclear waste storage sites, is backing the study specifically to scrutinize how much new waste would be created and how it would be stored long-term, underscoring that the people already living with the risks want hard answers before any green light is given.

The Minnesota Department of Natural Resources is imposing spring open burning restrictions in 32 counties starting Monday, March 30, including key Twin Cities metro counties Anoka, Hennepin, Ramsey and Washington, because warm, dry conditions are driving up wildfire risk. During the ban, the DNR will not issue permits for burning brush or yard waste in these counties, and anyone who lights a fire that rekindles or escapes can be held liable for damages and suppression costs. Officials say more than 90% of Minnesota wildfires are human-caused, and the period after snowmelt but before green-up is when grass and brush fires spread fastest. Residents are being pushed toward alternatives like composting, chipping or hauling brush to collection sites, and the agency says restrictions and risk maps will be updated as conditions change on its wildfire danger and burning restrictions webpage. For metro homeowners used to spring burn piles, this is a hard stop backed by fines, not a suggestion.

The National Weather Service has issued a Red Flag Warning for the Twin Cities and much of central and southern Minnesota on Saturday, citing a dangerous mix of low humidity, gusty southwest winds and very dry ground fuels. From roughly noon to 7 p.m. in the metro, forecasters expect temperatures near 60 degrees, relative humidity of just 15-20%, and wind gusts of 35-45 mph, conditions under which any spark can turn into a fast-moving grass or brush fire. Parts of southern Minnesota will be under the warning even longer, from 10 a.m. to 9 p.m. The Weather Service is blunt that outdoor burning is not recommended and that any fires that do start are likely to spread rapidly. The warm, windy weekend pattern continues Sunday with highs near 70 before cooler, showery weather returns by mid-week, but Saturday is the critical window for fire risk around the metro.

The Minnesota Department of Health has updated statewide fish consumption guidelines after detecting PFAS in fish from the Vermillion River, which runs through Dakota County to Hastings and into the Mississippi. For the first time, MDH is telling sensitive populations — children under 15 and people who are pregnant, may become pregnant, or are breastfeeding — not to eat any fish species from the Vermillion, while limiting the general population there to one serving per week. The update also tightens or reiterates mercury-driven limits for northeast Minnesota and lays out detailed statewide serving recommendations by species, size and who is eating the fish, with large walleye and northern pike, and muskies, at the strictest end. PFAS, widely used by industry including 3M, is now classified as a human carcinogen, and advocates have long warned that these 'forever chemicals' would eventually show up in metro-area fish. For Twin Cities anglers who rely on local rivers for food, this is a concrete signal that contamination has moved from abstract maps and lawsuits into the fish on their stringers, with the state advising caution long before anyone tastes a symptom.

Xcel Energy says roughly 200 gallons of mineral oil leaked at the Monticello nuclear plant, and the company now confirms a small amount has appeared as a sheen along the Mississippi River shoreline, walking back an earlier statement that no oil reached the river. Xcel says its first sign of abnormal oil levels came Monday afternoon (earlier than first reported), containment and absorbent booms were placed in the discharge canal and on the river Tuesday, but the company has not quantified how much oil entered the river or how far downstream it has been seen; the Minnesota Pollution Control Agency is monitoring and working with Xcel to assess the impact.

The St. Paul City Council has passed a resolution formally asking the Minnesota Pollution Control Agency to force Ford Motor Co. to do more cleanup at the former Ford assembly plant site in Highland Park, now being redeveloped as Highland Bridge. Council members say new testing has found lingering contamination that wasn't adequately addressed under earlier remediation plans, and they want MPCA to hold Ford to a stricter standard before more building goes up on the river bluff. The move signals the city no longer trusts Ford's assurances or the original regulatory sign-off to fully protect nearby residents, workers and the Mississippi River corridor. Neighbors who've watched the site transition from heavy industry to high-dollar housing are already questioning online whether regulators went too easy on a major corporation, and whether buyers were given the full story up front. If MPCA leans on Ford, it could mean additional investigation, soil removal, vapor controls or construction slowdowns at one of St. Paul's signature redevelopment projects.

The U.S. House voted to revoke a mining ban in the Superior National Forest, sending H.J. Res. 140 to the Senate and prompting hundreds of protesters at the Minnesota Capitol who oppose lifting federal protections upstream of the Boundary Waters. Friends of the Boundary Waters executive director Chris Knopf warned water from the affected lands flows directly into the BWCA and could be fouled by mining, while outfitter Ginny Nelson and Mining Minnesota executive director Julie Lucas acknowledged local economic stakes and said any mine must first prove it will not harm the wilderness.

Eagan has approved what reports call Minnesota's first-ever one-year moratorium on data center and cryptocurrency operations to study potential neighborhood and power impacts. City staff will evaluate issues including power-grid capacity, noise, traffic, heat, water use and tax implications, review how other Minnesota communities are responding, and the pause covers projects within 500 feet of residential zoning or drawing more than 20 megawatts, with draft ordinances expected before the moratorium ends.

The Minnesota DNR is warning ice anglers — including those in the Twin Cities who keep houses on nearby lakes — to plan now for removing their shelters as March deadlines approach amid unusually warm weather and thinning ice. Permanent shelters must be off southern inland waters by March 2, northern inland waters by March 16, and Minnesota-Canada border waters by March 31; after those dates, any shelter on the ice overnight has to be occupied. Officials stress that houses cannot be left at public access sites and that owners must remove all trash and blocking materials, even wood that has frozen into the ice, to avoid littering violations. The agency says record February warmth has already created weak spots on some lakes, raising the risk that both people and fish houses could break through if owners wait until the last minute. Lt. Col. Robert Gorecki said they want the season to "end on a high note," meaning shelters off by the deadlines and clean ice.

The Minnesota DNR says it will spend about $325,000 to replace Lake Alice's 1960s-era water control structure at William O'Brien State Park in Washington County after a failed valve in August 2025 nearly drained the artificial lake, killing fish and closing the beach. Design work is slated for winter 2026, with permitting, land and archaeological surveys and other field work in summer 2026, and on-the-ground construction and dredging of the adjoining St. Croix River public access set to begin spring 2027 and wrap up in fall 2027. Public recreation on Lake Alice itself will be shut down until the project is finished, though the park's river access will stay open in 2026 as water levels allow, meaning Twin Cities visitors can't swim or paddle that lake for at least the next two summers. DNR officials say full replacement, rather than a patch job, is the most cost-effective long-term fix to make the impoundment and its outlet more resilient after the mechanical failure exposed just how vulnerable the system is. Metro park users who rely on William O'Brien for close-in lake time will have to adjust plans and watch for periodic construction impacts along the St. Croix as the work gets underway.

State officials unveiled Minnesota's 2026 Climate Action Framework on Feb. 11 at St. Paul's North End Community Center, an updated roadmap that leans into the statutory goal of 100% carbon-free electricity by 2040 and outlines more than 400 specific actions across seven sectors. Built off a 2022 framework and now tied to roughly 40 state laws and over $1 billion in climate-related funding, the plan targets big cuts in greenhouse-gas emissions from the power sector, transportation, building heat and agriculture, while promising job growth in clean-energy fields. MPCA says Minnesota has already distributed $95 million to more than 160 local governments in the past two years to help them prepare for climate impacts, money that includes Minneapolis, St. Paul and other metro cities working on flooding, heat and infrastructure upgrades. Near-term priorities include actually implementing 100% carbon-free electricity, accelerating EV adoption and transit decarbonization, cutting emissions from furnaces and boilers in homes and offices, and backing local infrastructure and disaster-response projects. For Twin Cities residents, this framework is the blueprint agencies and utilities will use to justify future rate cases, building-code changes, grant programs and transit or land-use decisions that will show up in monthly bills and neighborhood projects over the next decade.

Roofing manufacturer GAF Materials will shutter its north Minneapolis manufacturing plant, eliminating roughly 120 jobs at a long-time industrial site just south of the massive Upper Harbor riverfront redevelopment, according to a Minneapolis / St. Paul Business Journal report. The facility sits along the Mississippi near where the city and developers are building an amphitheater, health center, park space and housing, making the closure a significant shift for that corridor's remaining industrial footprint. The article previews the closure but, behind a paywall, is expected to detail timing, severance and whether any production or workers will be shifted to other GAF locations. For north-side residents, it's a hit to one of the few remaining blue-collar plants inside city limits at the same time nearby land is being repositioned for higher-end mixed use. The combination of job loss and changing land values will bear close watching as Minneapolis weighs what replaces GAF on a riverfront that's rapidly moving away from industry.

3M told FOX 9 it has met its pledge to stop manufacturing PFAS by the end of 2025, ending more than 70 years of production of the so-called 'forever chemicals' that contaminated east-metro groundwater and helped fuel a global pollution crisis. The Maplewood-based company, which began making PFAS in the 1950s for products such as Scotchgard, has already paid nearly $14 billion to settle PFAS lawsuits and paid Minnesota nearly $900 million in 2018 to fund east-metro drinking-water cleanup — money that is now running down even as contamination and lawsuits continue. 3M says it has invested $1 billion in water-treatment systems at its largest water-using facilities and will keep operating those to handle legacy pollution, but it has recently questioned some state and local remediation projects, raising fears in affected suburbs about who will pay to finish cleanup when settlement dollars are exhausted. The article also points readers to a FOX 9 documentary and timeline showing internal 3M research and company decisions that, according to plaintiffs and regulators, delayed public disclosure of PFAS dangers.

Minnesota state regulators have ruled that electricity from burning municipal solid waste and some types of wood/biomass can be treated as 'carbon-free' under the state's 2040 carbon-free standard, a decision with major implications for utilities that serve the Twin Cities. The Public Utilities Commission's interpretation effectively keeps metro-area garbage burners and biomass contracts in the portfolio of resources utilities can rely on to meet the mandate, even though the plants still emit greenhouse gases and local pollutants. Supporters argue these facilities help manage waste streams and provide reliable baseload or dispatchable power that wind and solar can't always match, while environmental and climate advocates call the move a shell game that could lock in higher pollution in already overburdened neighborhoods. The ruling is expected to guide Xcel Energy's and other utilities' next integrated resource plans and could tilt future rate cases and infrastructure investments that directly affect Minneapolis-Saint Paul bills, air quality, and siting battles.

A rare G4 geomagnetic storm has already produced widespread auroras and could bring vivid northern lights to Minnesota Monday evening, with the best viewing chances in the Pacific Northwest, eastern Dakotas and Minnesota. If G4 levels return the display could be visible as far south as Alabama and Northern California; experts warn this may be the strongest solar radiation storm in more than 20 years (the last S4-level event was in 2003), though local cloud cover will affect visibility.

Enbridge will pay $2.8 million to resolve a breach of the Moose Lake aquifer that occurred during pipeline construction, a finalized settlement that includes the Minnesota DNR enforcement package of environmental projects, a civil penalty, contingency funds and monitoring. Earlier reports had highlighted a $1.6 million component, but the total financial obligation is $2.8 million.

The Minnesota Department of Agriculture is urging residents, including those in the Twin Cities metro, to dispose of Christmas trees and holiday greenery through curbside collection or official drop-off sites rather than dumping them in woods or backyard compost, to prevent invasive insects and plant diseases from spreading. Officials cite risks from pests such as elongate hemlock scale, boxwood blight and round leaf bittersweet—especially on trees and boughs imported from other states—and ask anyone who suspects an infestation to contact the MDA's Report a Pest line at 1-888-545-6684.

The U.S. House of Representatives on Dec. 18, 2025, passed a bill to remove the gray wolf from the federal Endangered Species Act list, sending the measure to the Senate. If it becomes law, federal protections would be lifted and management of wolves would revert to states, including Minnesota, potentially changing how the species is managed statewide.

The U.S. Environmental Protection Agency signaled it will abandon a tougher national fine-particulate (PM2.5) air-quality standard on Nov. 25, 2025. Reversing the stricter limit would affect how Minnesota and Twin Cities regulators assess air quality and industrial permitting, with implications for public health and compliance planning if the change proceeds through rulemaking.

Washington County Parks will waive entry fees at all 10 county parks and regional trails on Friday, Nov. 28, while the Minnesota DNR will waive vehicle permits at all 73 state parks the same day. Some parks will host free programs, including a naturalist-led hike at Wild River State Park; Dakota and Ramsey county parks do not require vehicle permits.

The Twin Cities hit a record high of 56°F on Nov. 23, breaking a roughly 120-year mark. The NWS says a storm will bring rain Tuesday—then change to snow late Tuesday into Wednesday (metro timeline roughly 9 a.m.-5 p.m. rain, changeover 5 p.m.-2 a.m., snow 2-9 a.m. Wed), with 1-2 inches expected in the Twin Cities (3-6 inches in central/northern MN), gusts over 40 mph possible in central Minnesota and a winter storm watch in effect for northern Minnesota and eastern North Dakota; wet roads could freeze and create travel hazards.

The Twin Cities reached 72°F Friday — the warmest temperature ever recorded this late in the season in records back to 1872 — while St. Cloud tied its daily high at 68°F. State climatologist says autumn 2025 is likely to rank among Minnesota's top-10 warmest seasons and nearly 63% of the state is abnormally dry or in drought, though a weak cold front should bring temperatures closer to normal in the coming days.

Hennepin County dropped a proposed second 'vertical' access at Lake Minnetonka's North Arm public landing in Orono after resident and city pushback, revising its redesign to add a picnic area instead. The county still plans safety and sustainability upgrades — including ramp realignment, parking changes, stormwater controls, shoreline pods for anglers/paddlers, lighting and solar features — and Commissioner Heather Edelson said the controversy will spur broader coordination among 14 lakeshore cities, the county, LMCD and the DNR on commercial use of public landings.

The EPA under Administrator Lee Zeldin proposed loosening parts of a Biden-era 2023 rule that accelerates the phaseout of hydrofluorocarbons (HFCs) under the 2020 AIM Act, arguing businesses need more time and flexibility. The plan, which follows a September step easing requirements for cold-storage warehouses and delaying some compliance to 2032, would affect grocery chains, refrigeration firms, and HVAC companies nationwide, including in the Twin Cities, while environmental groups warn it will worsen climate pollution and disrupt ongoing industry transitions.

The Cottage Grove City Council voted 5-0 on Nov. 6 to deem adequate the final environmental impact statement for Amrize Nelson's proposal to shift and expand sand-and-gravel mining into the Mississippi River backwaters near Lower Grey Cloud Island, moving the project to state and federal permitting. Friends of the Mississippi River objected, arguing shoreline mining is illegal under MRCCA rules, while the mayor said the three-year review only assessed EIS adequacy; the expansion would tap about 400 acres and extend mine life by 20-25 years.

NOAA's Space Weather Prediction Center issued a strong geomagnetic storm watch as a coronal mass ejection is expected to arrive between Thursday evening, Nov. 6, and Friday morning, Nov. 7, potentially making northern lights visible across Minnesota, including the Twin Cities' darker outskirts. Forecasters do not expect major radio or communications disruptions; a bright moon may reduce visibility, and viewing could continue Friday night depending on solar activity.

After the Minneapolis Park and Recreation Board considered closing the Lake of the Isles outdoor skating rink due to climate pressures and budget shortfalls, a neighborhood campaign led by Kenwood resident Janet Hallaway gathered nearly 3,000 signatures, prompting staff to keep the rink open for the upcoming winter season. District 4 Park Commissioner Elizabeth Shaffer said the push also spurred plans to restore and maintain several other rinks that were slated for closure or were closed last year.

St. Paul Parks and Recreation says 32 recently planted trees were found cut a few feet above the ground along Shepard Road south of the Smith Avenue High Bridge on Friday, Oct. 24. The trees were planted last fall with nonprofit partner Tree Trust; officials are determining replacement options but no funding source is identified. Police are investigating, and the city notes a similar November 2024 incident in the same area destroyed 60 trees, causing roughly $40,000 in damage.

The Minnesota DNR will close Afton State Park and William O'Brien State Park in Washington County to the public for a weekend deer hunt. The temporary closures are intended to facilitate the controlled hunt and maintain visitor safety, with normal access resuming after the weekend.

Minnesota launched a 10-year Drinking Water Action Plan to tackle PFAS and nitrate contamination, with the Minnesota Department of Health reporting 97% of the state's drinking water meets federal standards while about 3% of communities fall below standards due to excessive nitrate and arsenic. The plan — financed by the Clean Water Fund (which expires in 2034) and updated every two years — directs the Clean Water Council to fund grants for testing and remediation, cites projects like a $330 million Woodbury treatment plant funded in part by the 3M settlement, and responds to more PFAS-positive residential wells and a PFAS plume moving toward the Mississippi and St. Croix rivers.

Forecasts had warned of record warmth — even a possible 91°F — and gusty 30-40 mph winds Saturday with overnight lows in the low 70s Friday night. Saturday's high reached 90°F in the Twin Cities, topping the previous 89°F record, and other Minnesota locations also set records (Hibbing 83°F, Brainerd 86°F, Rochester 86°F, Duluth 84°F); cooler weather is expected Sunday with highs near 78°F and a further cooldown into the 60s next week as winds shift.

The Arden Hills City Council will take public comment Monday on proposed changes to its backyard poultry ordinance that would allow residents to keep ducks and loosen chicken rules. The proposal would raise the chicken limit from three to seven, permit larger coops, allow fenced-yard roaming, and enable coops in detached garages; a staff memo notes six metro cities already allow ducks and the Planning Commission recommended approval 7-0.

Urban farm activists seeking to buy Minneapolis' Roof Depot industrial site in the East Phillips neighborhood missed a city-imposed deadline to complete the purchase. The lapse puts the future of the long-disputed site back in the City of Minneapolis' hands as officials determine next steps for the property.
