The Alaska Gold Rush town of Nome faced a bleak winter. It was hundreds of miles from anywhere, cut off by the frozen sea and unrelenting blizzards, and under siege from a contagious disease known as the “strangling angel” for the way it suffocated children.
Now, 100 years later, Nome is remembering its saviors — the sled dogs and mushers who raced for more than five days through hypothermia, frostbite, gale-force winds and blinding whiteouts to deliver life-saving serum and free the community from the grip of diphtheria, The Associated Press reported.
Among the events celebrating the centennial of the 1925 “Great Race of Mercy” are lectures, a dog-food drive and a reenactment of the final leg of the relay, all organized by the Nome Kennel Club.
Remembering the mushers and dogs for ‘heroic effort’ “There’s a lot of fluff around celebrations like this, but we wanted to remember the mushers and their dogs who have been at the center of this heroic effort and ... spotlight mushing as a still-viable thing for the state of Alaska,” said Diana Haecker, a kennel club board member and co-owner of Alaska’s oldest newspaper, the Nome Nugget.
“People just dropped whatever they were doing," she said. "These mushers got their teams ready and went, even though it was really cold and challenging conditions on the trail.”
Other communities are also marking the anniversary — including the village of Nenana, where the relay began, and Cleveland, Ohio, where the serum run's most famous participant, a husky mix named Balto, is stuffed and displayed at a museum.
Jonathan Hayes, a Maine resident who has been working to preserve the genetic line of sled dogs driven on the run by famed musher Leonhard Seppala, is recreating the trip. Hayes left Nenana on Monday with 16 Seppala Siberian sled dogs, registered descendants of Seppala's team.
The historic trek to neutralize the diphtheria epidemic in Nome Diphtheria is an airborne disease that causes a thick, suffocating film to develop at the back of the throat; it was once a leading cause of death for children. The antitoxin used to treat it was developed in 1890, and a vaccine in 1923; it is now exceedingly rare in the U.S.
Nome, western Alaska’s largest community, had about 1,400 residents a century ago. Its most recent supply ship had arrived the previous fall, before the Bering Sea froze, without any doses of the antitoxin. Those the local doctor, Curtis Welch, had were outdated, but he wasn't worried. He hadn’t seen a case of diphtheria in the 18 years he had practiced in the area.
Within months, that changed. In a telegram, Welch pleaded with the U.S. Public Health Service to send serum: "An epidemic of diphtheria is almost inevitable here.”
The first death was a 3-year-old boy on Jan. 20, 1925, followed the next day by a 7-year-old girl. By the end of the month, there were more than 20 confirmed cases. The city was placed under quarantine.
West Coast hospitals had antitoxin doses, but it would take time to get them to Seattle and then onto a ship for Seward, an ice-free port south of Anchorage. In the meantime, enough for 30 people was found at an Anchorage hospital.
It still had to get to Nome. Airplanes with open-air cockpits were ruled out as unsuited for the weather. There were no roads or trains that reached Nome.
Instead, officials shipped the serum by rail to Nenana in interior Alaska, some 675 miles (1,086 kilometers) from Nome via the frozen Yukon River and mail trails.
Thanks to Alaska’s new telegraph lines and the spread of radio, the nation followed along, captivated, as 20 mushers — many of them Alaska Natives — with more than 150 dogs relayed the serum to Nome. They battled deep snow, whiteouts so severe they couldn’t see the dogs in front of them, and life-threatening temperatures that plunged at times to minus 60 degrees Fahrenheit (minus 51 degrees Celsius).
The antitoxin was transported in glass vials covered with padded quilts. Not a single vial broke.
Seppala, a Norwegian settler, left from Nome to meet the supply near the halfway point and begin the journey back. His team, led by his dog Togo, traveled more than 250 miles (320 kilometers) of the relay, including a treacherous stretch across frozen Norton Sound.
After about 5 1/2 days, the serum reached its destination on Feb. 2, 1925. A banner front-page headline in the San Francisco Chronicle proclaimed: “Dogs victors over blizzard in battle to succor stricken Nome.”
The official record listed five deaths and 29 illnesses. It’s likely the toll was higher; Alaska Natives were not accurately tracked.
Balto gains fame as unlikely dog to bring serum to Nome Seppala and Togo missed the limelight that went to his assistant, Gunnar Kaasen, who drove the dog team led by Balto into Nome. Balto was another of Seppala’s dogs, but was used to only haul freight after he was deemed too slow to be on a competitive team.
Balto was immortalized in movies and with statues in New York's Central Park and one in Anchorage intended as a tribute to all sled dogs. He received a bone-shaped key to the city of Los Angeles, where legendary movie actress Mary Pickford placed a wreath around his neck.
But he and several team members were eventually sold and kept in squalid conditions at a dime museum in Los Angeles. After learning of their plight, an Ohio businessman spearheaded an effort to raise money to bring them to Cleveland. After dying in 1933, Balto was mounted and placed on display at the Cleveland Museum of Natural History.
Iditarod pays homage to the serum run Today, the most famous mushing event in the world is the Iditarod Trail Sled Dog Race, which is not based on the serum run but on the Iditarod Trail, a supply route from Seward to Nome. Iditarod organizers are nevertheless marking the serum run's centennial, with a series of articles on its website and by selling replicas of the medallions each serum run musher received a century ago, race spokesperson Shannon Noonan said in an email. This year's Iditarod starts March 1.
“The Serum Run demonstrated the critical role sled dogs played in the survival and communication of remote Alaskan communities, while the Iditarod has evolved into a celebration of that tradition and Alaska’s pioneering spirit,” Noonan said.

Rain Further Batters Storm-Hit Portugal, Thousands Evacuated

More ‌heavy rain flooded several rural areas in the north of storm-battered Portugal on Wednesday, leaving levees at risk of bursting around the medieval city of Coimbra and forcing authorities to evacuate about 3,000 residents as a precaution.

A succession of deadly storms has hammered mostly central and southern parts of the country since late January, blowing roofs off houses, flooding several towns and leaving hundreds of thousands without electricity for days. At least 15 people have died as a consequence of the storms, including indirect ‌victims.

As the ‌storms let up this week, a weather ‌phenomenon ⁠known as an "atmospheric river" - ⁠a wide corridor of concentrated water vapor carrying massive amounts of moisture from the tropics - brought new downpours, affecting the north to a greater extent.

RISK OF DAM OVERFLOWING

Municipal authorities in Coimbra ordered the precautionary evacuation late on Tuesday of around 3,000 people most at risk from the River Mondego bursting its banks, ⁠and the operation was still under way on ‌Wednesday, with police making door-to-door checks ‌and bussing residents to shelters.

Regional Civil Protection official Carlos Tavares ‌said on Wednesday the situation could worsen between late Wednesday ‌and midday Thursday, as the rain could cause the Aguieira dam, 35 km northeast of Coimbra, "to overflow, sweep away levees and trigger further flooding".

Part of Coimbra's ancient city wall, on a hillside in one ‌of Europe's oldest university towns and a UNESCO World Heritage site, collapsed, shutting the road below ⁠and forcing ⁠the closure of the municipal market, the city hall said.

Prime Minister Luis Montenegro was due in Coimbra to oversee the emergency response after Interior Minister Maria Lucia Amaral resigned following criticism from opposition parties and local communities over what they described as the authorities' slow and failed response to devastating Storm Kristin two weeks ago.

In central Portugal, just across the River Tagus from Lisbon, authorities evacuated the village of Porto Brandao due to the risk of landslides, and around 30 people were removed from their homes after a landslide in the neighboring beachside area of Caparica.

From Argentina to Australia to South Africa, record heat and raging wildfires are rampaging through the Southern Hemisphere at the start of 2026, with scientists predicting that even more extreme temperatures could lie ahead - and possibly another global annual high - after three of the hottest years on record.

In January, a record-setting heat dome enveloped Australia, sending temperatures near 50 degrees C (122 degrees F) while heat and catastrophic wildfires gripped parts of South America, setting remote parts of Argentina's Patagonia ablaze and killing 21 people in coastal towns in Chile. In addition, South Africa has been experiencing its worst wildfires in years.

The extremes are occurring even as the world remains under the cooling influence of a weak La Nina, a climate cycle marked by cooler waters in the central and eastern Pacific that began in December 2024. Despite this moderating factor, temperatures are reaching record highs in various locales.

"This means the effect of human-caused climate change is overwhelming natural variability," said climate scientist Theodore Keeping of Imperial College London and the international research collaboration World Weather Attribution, who specializes in research on wildfires and extreme heat.

"As we transition into a neutral or even El Nino phase, we'll expect the incidence of extreme heat events around the world to be further amplified," Keeping added.

El Nino typically has the opposite effect of La Nina, warming the central and eastern Pacific and boosting global temperatures.

This year is forecast to be about 1.46 degrees C (2.6 degrees F) above pre-industrial levels, which would make it the fourth consecutive year to be higher than 1.4 degrees C (2.5 degrees F) above pre-industrial levels, according to Adam Scaife, head of the long-range prediction at the United Kingdom's national weather ‌and climate service.

The 2015 ‌international climate treaty, known as the Paris Agreement, aimed to keep warming below 1.5 degrees C (2.7 degrees F) above pre-industrial levels.

"If a big ‌El Nino ⁠were to develop ⁠quickly in 2026 then it's still possible 2026 could be a record," Scaife said. The World Meteorological Organization said last month that the past three years were the warmest on record.

FIRE RAGES FROM WOODS TO WATER

While most wildfires are caused by human activity, they are also a natural part of many ecosystems. Persistent heat, drought and extreme temperatures, however, are turning once-manageable fires into increasingly uncontrollable and destructive events.

Many ecosystems are not adapted to such hot, dry conditions, allowing fires to grow larger and more intense, often causing permanent damage, Keeping said.

The fires that burned through Argentina's Los Alerces National Park illustrate the shift, according to meteorologist Carolina Vera of the Center for Ocean and Atmospheric Research at the University of Buenos Aires.

The park, a UNESCO World Heritage site, is home to trees that have lived more than 3,000 years.

Local officials determined that a lightning strike caused the fire. The blaze initially was under control. But Vera said a heat wave and strong winds caused it to spread about 20 km (12 miles) in a single day, making it the worst wildfire there ⁠in two decades.

The region has been drought-stricken since 2008. Temperatures during the first two weeks of January were about 6 degrees C (11 degrees F) above ‌normal.

"These fires used to burn themselves out and form part of the forest's natural dynamics," Vera said.

"This is an example of ‌how climate change can alter a natural fire, because it appeared to be caused by lightning," Vera said.

There are no towns in that remote area.

Fires erupted in the southern part of neighboring Chile later in January and ‌crossed into the greater Concepcion area, the country's third-largest metropolitan region, destroying hundreds of homes and killing 21 people in coastal communities.

Keeping said the blazes mirrored recent disasters in places such as ‌Los Angeles, Athens and the Hawaiian island of Maui.

"Where there's been the greatest loss of life, it almost always comes down to evacuation being difficult or impossible," Keeping said. "That's particularly true in regions affected by strong downslope winds toward the coast."

WHIRLWINDS OF FIRE

About 80% of Punta de Parra, a small coastal town in southern Chile surrounded by hills and forests, was destroyed.

Punta de Parra residents said they had little time to evacuate. Doralisa Silva, 34, said she heard about a fire in a nearby community the night the blaze reached the town.

"Out of nowhere, the forest started burning and all the houses caught fire," Silva said. "The fire was on us in the blink ‌of an eye. There was nothing we could do."

Silva said her family was among the last to try to flee because they had no vehicle. Silva said flames blocked their exit as embers rained down as she and her partner Hermes Barrientos fled with their ⁠2-year-old daughter.

Barrientos said winds of nearly 70 km ⁠per hour (43.5 mph) whipped through the area, creating whirlwinds of fire that spread to the beach and trapped residents. The family and others eventually found refuge in a large dirt field at the center of town, and spent the night watching their community burn.

A FUTURE FILLED WITH FIRES

Record-breaking heat in southeastern Australia has also fueled the country's worst fires since the deadly 2019-2020 season, when 33 people were killed.

In addition, the 2025-2026 fire season has been the most severe in South Africa in a decade, according to officials, killing wildlife and hitting tourist destinations such as Mossel Bay and Franschhoek.

"The hot, dry and windy conditions that drive the most extreme wildfires are becoming more intense and more likely," Keeping said. "And it's happening all around the world."

The Southern Hemisphere has warmed by about 0.15 to 0.17 degrees C (0.27 to 0.30 degrees F) per decade since the 1970s, compared to 0.25 to 0.30 degrees C (0.45 to 0.54 degrees F) in the Northern Hemisphere - largely because its vast oceans absorb heat more slowly and because of Antarctic meltwater.

Still, southern land masses are now warming at similar rates to northern land masses, and contrasts between warming land and cold meltwater can intensify weather patterns, leading to prolonged heat waves, droughts or flooding.

Keeping said adaptation is critical, including authorities managing vegetation near cities and developing effective evacuation plans, and builders using fire-resistant materials. Wildfires are inflicting mounting economic damage. A 2026 report by insurance broker Aon estimated global insured wildfire losses at $42 billion in 2025, up from an average of $4 billion annually between 2000 and 2024. The Los Angeles fires last year were the costliest on record.

Swiss Re, the world's second-largest reinsurer, found that wildfires accounted for about 1% of global insured losses from natural disasters before 2015, but now represent 7%, with economic losses linked to fires rising by about $170 million a year since 1970.

"You actually cannot stop a lot of these really large intense wildfires. They're simply too big," Keeping said.

The most important way forward, Keeping said, is to "have a serious conversation about limiting future climate change to prevent this issue from worsening."

Noise pollution is affecting bird behavior across the globe, disrupting everything from courtship songs to the ability to find food and avoid predators, a large-scale new analysis showed on Wednesday.

Researchers reviewed nearly four decades of scientific work and found that noises made by humans were interfering with the lives of birds on six continents and having "strong negative effects" on reproduction success.

Previous research on individual species has shown that single sources of anthropogenic noise -- such as planes, traffic and construction -- can affect birds as it does other wildlife.

But for this study, the team performed a wider analysis by pooling data published since 1990 across 160 bird species to see if any broader trends could be established.

The study, published in the journal Proceedings of the Royal Society B, found clear evidence of a "pervasive" impact of noise pollution on birds worldwide.

"We found that noise significantly impacts communication risk behaviors, foraging, aggression and physiology and had a strong effect on habitat use and a negative impact on reproduction," AFP quoted it as saying.

This is because birds rely on acoustic information to survive, making them particularly vulnerable to the modern din produced by cars, machinery and urban life.

"They use song to find mates, calls to warn of predators, and chicks make begging calls to let their parents know they're hungry," Natalie Madden, who led the research while at the University of Michigan, said in a statement.

"So if there's loud noise in the environment, can they still hear signals from their own species?"

In some cases, noise pollution interrupted mating displays, caused males to change their courtship songs, or masked messages between chicks and parents.

The study included many common species such as European robins and starlings, house sparrows, and great tits.

The response varied between species, with birds that nest close to the ground suffering greater reproductive harm, while those using open nests experienced stronger effects on growth.

Birds living in urban areas, meanwhile, tended to have higher levels of stress hormones than those outside of cities.

Some 61 percent of the world's bird species have declining populations, mostly due to habitat loss driven by expanding agriculture and logging, the International Union for Conservation of Nature said in October.

The study authors said that noise pollution was an "underappreciated consequence" of humanity's impact on nature, especially compared to biodiversity loss and climate change.

But some relatively simple fixes could make a big difference for birds, they said.

Madden told AFP that shifting from noisier cars and landscaping tools such as mowers and leaf blowers to electric-powered alternatives was one idea.

Another could be "running machinery outside peak breeding seasons, avoiding activity when birds are migrating through an area, or shifting construction away from habitats that support vulnerable species", she added.

Buildings could also be adapted to muffle sound in the same way they are constructed to improve visibility and minimize bird collisions, said the study's senior author Neil Carter, from the University of Michigan.

"So many of the things we're facing with biodiversity loss just feel inexorable and massive in scale, but we know how to use different materials and how to put things up in different ways to block sound," he said.
