Las Vegas — Roughly 130 million people were under threat over the weekend and into next week from a long-running heat wave that broke or tied records with dangerously high temperatures and is expected to shatter more from East Coast to West Coast, forecasters said.

Ukiah, north of San Francisco, hit 117 degrees Fahrenheit (47 degrees Celsius) on Saturday, breaking the city’s record for the date and tying its all-time high. Livermore, east of San Francisco, hit 111 F (43.8 C), breaking the daily maximum temperature record of 109 F (42.7 C) set more than a century ago in 1905.

Las Vegas tied the record of 115 F (46 C), last reached in 2007, and Phoenix topped out at 114 F (45.5 C), just shy of the record of 116 F (46.7 C) dating to 1942.

The National Weather Service said it was extending the excessive heat warning for much of the Southwest through Friday.

“A dangerous and historic heatwave is just getting started across the area, with temperatures expected to peak during the Sunday-Wednesday timeframe,” the National Weather Service in Las Vegas said in an updated forecast.

In Las Vegas, where the mercury hit 100 F (37.7 C) by 10:30 a.m., Marko Boscovich said the best way to beat the heat is in a seat at a slot machine with a cold beer inside an air-conditioned casino.

“But you know, after it hits triple digits it’s about all the same to me,” said Boscovich, who was visiting from Sparks, Nevada to see a Dead & Company concert Saturday night at the Sphere. “Maybe they’ll play one of my favorites — ‘Cold Rain and Snow.’”

In more humid parts of the country, temperatures could spike above 100 F (about 38 C) in parts of the Pacific Northwest, the mid-Atlantic and the Northeast, said Jacob Asherman, a weather service meteorologist.

Heat records shattered across the Southwest

Meteorologists predicted that temperatures would be near daily records in the region through most, if not all, of the coming week, with lower desert highs reaching 115 to 120 degrees F (46.1 to 48.8 C).

Rare heat advisories were extended even into higher elevations including around Lake Tahoe, on the border of California and Nevada, with the National Weather Service in Reno, Nevada, warning of “major heat risk impacts, even in the mountains.”

“How hot are we talking? Well, high temperatures across (western Nevada and northeastern California) won’t get below 100 degrees (37.8 C) until next weekend,” the service posted online. “And unfortunately, there won’t be much relief overnight either.”

Indeed, Reno hit a high of 104 F (40 C) on Saturday, smashing the old record of 101 F (38.3 C).

More extreme highs are in the near forecast, including 129 F (53.8 C) for Sunday at Furnace Creek, California, in Death Valley National Park, and then around 130 F (54.4 C) through Wednesday.

The hottest temperature ever officially recorded on Earth was 134 F (56.67 C) in July 1913 in Death Valley, eastern California, though some experts dispute that measurement and say the real record was 130 F (54.4 C), recorded there in July 2021.

The worst is yet to come across the West and mid-Atlantic

Triple-digit temperatures are likely in the West, between 15 and 30 F (8 and 16 C) higher than average into next week, the National Weather Service said.

The Eastern U.S. also was bracing for more hot temperatures. Baltimore and others parts of Maryland were under an excessive heat warning as heat index values could climb to 110 F (43 C), forecasters said.

“Drink plenty of fluids, stay in an air-conditioned room, stay out of the sun, and check up on relatives and neighbors,” read a National Weather Service advisory for the Baltimore area. “Young children and pets should never be left unattended in vehicles under any circumstances.”

Deaths are starting to mount

In Arizona’s Maricopa County, which encompasses Phoenix, there have been at least 13 confirmed heat-related deaths this year, along with more than 160 other deaths suspected of being related to heat that are still under investigation, according to a recent report.

That does not include the death of a 10-year-old boy last week in Phoenix who suffered a “heat-related medical event” while hiking with family at South Mountain Park and Preserve, according to police.

California wildfires fanned by low humidity, high temperatures

Firefighters dispatched aircraft and helicopters to drop water or retardant on a series of wildfires in California.

In Santa Barbara County, northwest of Los Angeles, the Lake Fire has scorched more than 19 square miles (49 square kilometers) of grass, brush and timber. Firefighters said the blaze was displaying “extreme fire behavior” and had the “potential for large growth” with high temperatures and low humidity.

Festival revelers meet the heat with cold water and shade

At the Waterfront Blues Festival in Portland, Oregon, music fans coped by drinking cold water, seeking shade or freshening up under water misters. Organizers of the weekend revelries also advertised free access to air conditioning in a nearby hotel.

Angelica Quiroz, 31, kept her scarf and hat wet and applied sunscreen.

“Definitely a difference between the shade and the sun,” Quiroz said Friday. “But when you’re in the sun, it feels like you’re cooking.”

CAPE TOWN, South Africa — Scientists in South Africa have been stunned to discover that termite mounds that are still inhabited in an arid region of the country are more than 30,000 years old, meaning they are the oldest known active termite hills.

Some of the mounds near the Buffels River in Namaqualand were estimated by radiocarbon dating to be 34,000 years old, according to the researchers from Stellenbosch University.

“We knew they were old, but not that old,” said Michele Francis, senior lecturer in the university’s department of soil science who led the study. Her paper was published in May.

Francis said the mounds existed while saber-toothed cats and woolly mammoths roamed other parts of the Earth and large swathes of Europe and Asia were covered in ice. They predate some of the earliest cave paintings in Europe.

Some fossilized termite mounds have been discovered dating back millions of years. The oldest inhabited mounds before this study were found in Brazil and are around 4,000 years old. They are visible from space.

Francis said the Namaqualand mounds are a termite version of an “apartment complex” and the evidence shows they have been consistently inhabited by termite colonies.

Termite mounds are a famous feature of the Namaqualand landscape, but no one suspected their age until samples of them were taken to experts in Hungary for radiocarbon dating.

“People don’t know that these are special, ancient landscapes that are preserved there,” Francis said.

Some of the biggest mounds — known locally as “heuweltjies,” which means little hills in the Afrikaans language — measure around 30 meters across. The termite nests are as deep as 3 meters underground.

Researchers needed to carefully excavate parts of the mounds to take samples, and the termites went into “emergency mode” and started filling in the holes, Francis said.

The team fully reconstructed the mounds to keep the termites safe from predators like aardvarks.

Francis said the project was more than just a fascinating look at ancient structures. It also offered a peek into a prehistoric climate that showed Namaqualand was a much wetter place when the mounds were formed.

The southern harvester termites are experts at capturing and storing carbon by collecting twigs and other dead wood and putting it back deep into the soil. That has benefits in offsetting climate change by reducing the amount of carbon emitted into the atmosphere.

It’s also good for the soil. Masses of wildflowers bloom on top of the termite mounds in a region that receives little rain.

Francis called for more research on termite mounds given the lessons they offer on climate change, sustaining ecosystems and maybe even for improving agricultural practices.

“We will do well to study what the termites have done in the mounds. They were thought to be very boring,” she said.

WASHINGTON — Scientists have revealed fossils of a giant salamanderlike beast with sharp fangs that ruled waters before the first dinosaurs arrived.

The predator, which was larger than a person, likely used its wide, flat head and front teeth to suck in and chomp unsuspecting prey, researchers said. Its skull was about 60 centimeters (2 feet) long.

“It’s acting like an aggressive stapler,” said Michael Coates, a biologist at the University of Chicago who was not involved with the work.

Fossil remnants of four creatures collected about a decade ago were analyzed, including a partial skull and backbone. The findings on Gaiasia jennyae were published Wednesday in the journal Nature. The creature existed some 40 million years before dinosaurs evolved.

Researchers have long examined such ancient predators to uncover the origins of tetrapods: four-legged animals that clambered onto land with fingers instead of fins and evolved to amphibians, birds and mammals including humans.

Most early tetrapod fossils hail from hot, prehistoric coal swamps along the equator in what’s now North America and Europe. But these latest remnants, dating back to about 280 million years ago, were found in modern-day Namibia, an area in Africa that was once encrusted with glaciers and ice.

That means tetrapods may have thrived in colder climates earlier than scientists expected, prompting more questions about how and when they took over the Earth.

“The early story of the first tetrapods is much more complex than we thought,” said co-author Claudia Marsicano at the University of Buenos Aires, who was part of the research.

The creature’s name comes from the Gai-As rock formation in Namibia where the fossils were found and for the late paleontologist Jennifer Clack, who studied how tetrapods evolved.

portland, oregon — Roughly 130 million people were under threat Saturday and into next week from a long-running heat wave that already has broken records with dangerously high temperatures — and is expected to shatter more from East Coast to West Coast, forecasters said. 

Oppressive heat and humidity could team up to spike temperatures above 100 degrees Fahrenheit (about 38 degrees Celsius) in parts of the Pacific Northwest, the Mid-Atlantic and the Northeast, said Jacob Asherman, a meteorologist with the National Weather Service. 

In Oregon, records could be broken in cities including Eugene, Portland and Salem, Asherman said. Dozens of other records throughout the U.S. could fall, Asherman added, causing millions to seek relief from the blanket of heat in cooling centers from Bullhead City, Arizona, to Norfolk, Virginia. 

The National Weather Service said Saturday it was extending the excessive heat warning for much of the Southwest into Friday. 

“A dangerous and historic heatwave is just getting started across the area, with temperatures expected to peak during the Sunday-Wednesday timeframe,” the National Weather Service in Las Vegas said in an updated forecast. 

Excessive heat will likely continue through Friday, the service said. 

In sweltering Las Vegas, where the temperature hit 100 F (37.7 C) by 10:30 a.m., Marko Boscovich said the best way to beat the heat is in a seat at a slot machine with a cold beer inside an air-conditioned casino. 

“But you know, after it hits triple digits it’s about all the same to me,” said Boscovich, who was visiting from Sparks, Nevada, to see a Dead & Company concert later Saturday night at the Sphere. “Maybe they’ll play one of my favorites — ‘Cold Rain and Snow.'” 

Heat records being shattered across the southwest 

By 10:30 a.m. Saturday, the National Weather Service said the temperature already had risen to 100 F (36.6 C) in Phoenix, which saw a record high of 118 F (47.7 C) for Friday. 

Meteorologists predict temperatures will be near daily records region-wide through most, if not all, of the coming week with lower desert highs reaching 115 to 120 F (46.1 to 48.8 C). 

Rare heat advisories had been extended even into the upper elevations, including around Lake Tahoe, with the National Weather Service in Reno, Nevada, warning of “major heat risk impacts, even in the mountains.” 

“How hot are we talking? Well, high temperatures across (western Nevada and northeastern California) won’t get below 100 degrees (37.8 C) until next weekend,” the service posted online. “And unfortunately, there won’t be much relief overnight either.” 

A new heat record for the day was set Friday in California’s Death Valley — one of the hottest places on Earth — with the mercury climbing to 127 F (52.8 C). The old mark of 122 F (50 C) was last tied in 2013. 

Palm Springs, California, hit 124 F (51.1 C) Friday, breaking the city’s record of 123 F (50.5 C). 

More extreme highs are in the near forecast, including 129 F (53.8 degrees C) for Sunday at Furnace Creek in Death Valley National Park, and then around 130 (54.4 C) through Wednesday. The hottest temperature ever officially recorded on Earth was 134 degrees (56.67 C) in Death Valley in July 1913, though some experts dispute that measurement and say the real record was 130 F (54.4 C) recorded there in July 2021. 

Worst is yet to come 

The worst was yet to come across much of the West, with triple-digit temperatures likely higher than average into next week, the National Weather Service said.  

The Eastern U.S. also was bracing for more hot temperatures. Baltimore and other parts of Maryland were under an excessive heat warning, as heat index values could climb to 110 F (43 C), forecasters said.

Heat-related deaths mounting 

In Arizona’s Maricopa County, which encompasses Phoenix, there have been at least 13 confirmed heat-related deaths this year, along with more than 160 other suspected heat deaths are still under investigation, according to the county’s most recent report.

Lausanne, Switzerland — In the battle against drug use at the Paris Olympics, the International Testing Agency plans to deploy a more streamlined, high-tech approach to identify and target potential cheats.

In an interview with Agence France-Presse, Benjamin Cohen, director general of the ITA, said potential tools at its disposal included biological and performance passports as well as a mountain of other data.

Upgraded software, possibly using artificial intelligence, could also help; an investigative unit aided by whistleblowers was making inroads; and increased cooperation with sports bodies and police was bearing fruit.

The ITA, which was founded in 2018, runs the anti-doping program for the Olympics, the Tour de France and “more than 65 international organizations,” said Cohen.

The challenge was to refine the “risk analysis” and identify athletes to monitor using as little time and resources as possible, said Cohen, a Swiss lawyer who has headed the agency since its creation.

The problem is accentuated in the run-up to the Paris Games.

“We still have 30,000 potentially qualifying athletes and we cannot wait to have the final list to focus on the 11,000 participants,” Cohen said.

“Certain doping practices enable athletes to achieve results very quickly,” he said. “Traditionally the pre-Olympic period is high-risk time … the last moment to make a difference. Athletes know that they will be very closely monitored at the Olympics, so I would hope that very few, if any, will be tempted to take drugs in the Olympic Village in Paris.”

At the Games, only medalists are automatically tested, but the ITA wants to find ways to target potential dopers before the finish.

Cohen said the ITA tries to identify patterns. It looks at the demands of each discipline and the substances it might tempt athletes to use. Then the ITA looks at delegations and “the history of doping in that country.” Finally, it scrutinizes each individual athlete and “the development of his or her performances, any suspicious biological passport profiles, suspicious anti-doping tests and so on.”

“That’s hundreds of thousands of pieces of data.”

“Risk analysis”

“Today we have our own software, and the next stage” will involve “programming computers to extract this data, because we still do a lot of this work manually.”

After that, the ITA hopes to “seize all the opportunities offered by artificial intelligence,” provided “we use these new tools ethically.”

“If it’s done properly,” he said, “AI will enable us to go much further in risk analysis and prediction.”

The ITA is developing a “performance passport” as a counterpart to the long-established biological passport.

The objective is to “predict results on the basis of what an athlete has done over the last four years,” said Cohen.

“Artificial intelligence will enable us to say: ‘This is really an unusual result, which could suggest doping,'” he said. “It could help us flag them.”

The performance passport project was initially tested in swimming and weightlifting, two indoor sports in which athletes compete in identical environments each time.

Weightlifting also is one of the sports that have returned a vast number of positive tests at Summer Olympics.

In 2021, the ITA carried out “a major investigation into weightlifting,” and that enabled them to set up a specialized unit in cooperation with the sport.

Focus on cycling

It now has more than 10 such units. “Cycling is a particular focus,” but “other sports are beginning to understand the benefits of gathering intelligence, having anonymous sources and promoting whistleblowers.”

“It’s a new method that complements traditional testing.”

Cohen said the ITA has been working to build links with law enforcement and exploit “synergies.”

“They are bearing fruit,” he said, referring to the case of 23-year-old Italian cyclist Andrea Piccolo, arrested on June 21 by the Italian Carabinieri who caught him returning to the country with growth hormones.

“ITA asked the Italian authorities to open his luggage, which would not have been possible six years ago,” Cohen said.

“We carry out the controls, we monitor the performances of these athletes, we know the networks, the doctors involved and the drugs they are taking. And they can seize and open suitcases and enter hotel rooms.”

new york — The extent of Hurricane Beryl’s damage became clearer Friday, as communications were reestablished with the small, storm-ravaged eastern Caribbean islands and relief began to arrive. 

The Grenadian islands of Carriacou and Petit Martinique sustained the most severe damage when Beryl made landfall Monday as a Category 4 storm and later saw its winds strengthen to a Category 5. About 11,000 people inhabit the two islands. 

“The desalination plants have been knocked out; all of the cell towers have been knocked out; all of the fiber optic cables have been knocked out,” said Simon Springett, the United Nations resident coordinator for Barbados and the Eastern Caribbean. “The roads are impassable. We probably have about 95% of the housing stock destroyed. And by default, all of the local businesses, all the income-generating activities — and the list goes on.” 

Beryl is the first Category 5 hurricane on record in the Atlantic Ocean in June. The hurricane season runs until November 30 and officials with the National Oceanic and Atmospheric Administration are forecasting 17 to 25 named storms.

Springett, who briefed reporters from Grenada, said communications were only restored with Carriacou Thursday night. About 9,000 people live on the island known for its coral reefs and sandy beaches. 

“The entire island is completely affected,” he said. 

Rough seas hamper delivery of help

Springett said the relief operation has been complicated by extremely rough seas following the hurricane and airport control towers being knocked offline. 

“So, there is only fly-by visibility,” he said. “Even when things get into the airport, there are no roads to be able to access the goods.” 

He said a French naval vessel is due to arrive in Carriacou on Friday. Neighbors Guyana and Trinidad and Tobago also have sent support. 

The United Nations, which has nine agencies active in Grenada normally, is surging more staff in. Springett said a supply ship would be arriving Saturday from St. Vincent and the Grenadines to bring aid to the outer islands of the Grenadines and then continue to Carriacou and Petite Martinique. 

Three islands in St. Vincent and the Grenadines also were hit badly: Canouan, Union Island and Mayreau. Springett said about 15,500 people live there. 

One confirmed death in Jamaica

Beryl hit Jamaica Wednesday. It was the strongest storm there in over a decade, but the island was spared the worst. 

Dennis Zulu, U.N. resident coordinator for Jamaica, told reporters on the same briefing call that about 70% of people are without water and 40% without power. 

The island is a major tourism destination and Zulu said the government had moved quickly to reopen the main tourist airport at Montego Bay and to clear road access to resorts. 

“From preliminary assessments, very little harm came to the infrastructure in terms of tourist hotels and resorts,” Zulu said.  “So that is really positive.” 

He said at least one person was confirmed dead in Jamaica from Beryl and a flash flood warning remains in effect. There was damage to homes, but some government shelters were shutting after people had returned home. 

“Jamaica is up and running, if I may say that, and the government is moving seriously to ensure that,” Zulu said. 

The United Nations has made an initial allocation of $1.5 million from its emergency fund for Grenada and St. Vincent and the Grenadines. Another $2.5 million has been allocated for Jamaica.

BENGALURU, India — Months of scorching temperatures sometimes over 50 degrees Celsius (122 Fahrenheit) in parts of India this year — its worst heat wave in over a decade — left hundreds dead or ill. But the official number of deaths listed in government reports barely scratches the surface of the true toll and that’s affecting future preparations for similar swelters, according to public health experts. 

India now has a bit of respite from the intense heat, and a different set of extreme weather problems as monsoon rain lashes the northeast, but for months the extreme heat took a toll on large swaths of the country, particularly in northern India, where government officials reported at least 110 heat-related deaths. 

Public health experts say the true number of heat-related deaths is likely in the thousands but because heat is often not listed as a reason on a death certificate many heat deaths don’t get counted in official figures. The worry, they say, is that undercounting the deaths means the heat wave problem isn’t as prioritized as it should be, and officials are missing out on ways to prepare their residents for the scorching temperatures. 

All of India’s warmest years on record have been in the last decade. Studies by public health experts found that up to 1,116 people have died every year between 2008 and 2019 due to heat. 

Difficulties registering heat deaths 

As part of his work in public health, Srinath Reddy, the founder of the Public Health Foundation of India, has advised state governments on how to factor in heat when recording deaths. 

He found that as a result of “incomplete reporting, delayed reporting and misclassification of deaths,” heat-related deaths are significantly undercounted around the country. Despite national guidelines for recording deaths, many doctors — especially those in overcrowded public hospitals where resources are already strained — don’t follow it, he said. 

“Most doctors just record the immediate cause of death and attribution to environmental triggers like heat are not recorded,” Reddy said. That’s because heat deaths can be classified as exertional or non-exertional: Exertional is when a person dies due to direct exposure to high temperatures and non-exertional is when young children, older people or people with pre-existing health conditions become seriously ill or sometimes die from the heat, even if indoors. 

“The heatwave is the final straw for the second category of people,” said Dileep Mavalankar, former head of the Indian Institute of Public Health in Gandhinagar. “Most people dying during heat waves belong to this category but their deaths are not recorded as connected to the heat.” 

Mavalankar agreed the official number of heat deaths this year is an undercount. He said there were 40,000 recorded case of heat stroke, but only 110 deaths. “This is just 0.3% of the total number of heatstroke cases recorded, but usually heat deaths should be 20 to 30% of heatstroke cases,” he said. 

“We need to be counting deaths better,” Mavalankar said. “That is the only way we will know how severe the consequences of extreme heat are.”
