Extreme heat in July debilitates hundreds of millions worldwide

GENEVA — Soaring temperatures in July have had detrimental effects on the well-being of hundreds of millions of people worldwide who have found the monthlong extreme heat too hot to handle, according to the World Meteorological Organization.

“The extreme heat, which continued throughout July after a hot June … has had really, really devastating impacts on communities, on people’s health, on ecosystems, also on economies,” WMO spokesperson Clare Nullis told journalists Tuesday in Geneva.

“Extreme heat has a domino effect across society,” she said, noting that the world’s hottest day on recent record was registered on July 22. “All of this is really yet another unwelcome indication, one of many, of the extent that greenhouse gases from human activities are, in fact, changing our climate.”

WMO data show widespread, intense and extended heat waves have hit every continent in the past year and global average temperatures have set new monthly records for 13 consecutive months from June 2023 to June 2024.

“At least 10 countries in the past year have recorded daily temperatures of more than 50 degrees Celsius [122 degrees Fahrenheit] in more than one location,” Nullis said. “You can well imagine this is too hot for the body to handle.”

WMO reports that Death Valley in California, considered to be the hottest place on Earth, registered an average monthly temperature of 42.5 degrees Celsius (108.5 degree Fahrenheit) at Furnace Creek, “which is a record for the site and possibly the world.”

WMO normally does not measure monthly temperature records. But Randall Cerveny, chief rapporteur for the WMO’s committee for evaluating climate and weather extremes, said ”the record appeared to be reasonable and legitimate.”

While human-induced activity is largely responsible for the long-term warming trend, meteorologists cite above-average temperatures over large parts of Antarctica as another contributing factor.

According to the European Union’s Copernicus Climate Change Service, this has resulted in anomalies of more than 10-degrees Celsius above average in some areas, and above-average temperatures in parts of the Southern Ocean.

WMO climate expert Alvaro Silva said two consecutive heat waves that hit Antarctica over the last two years have contributed to record global temperatures.

“The reason is still under research, but it seems to be related with the daily sea ice extent,” he said, noting the Antarctic daily sea ice extent in June 2024 “was the second lowest on record. … This follows the lowest extent that we have in Antarctica in terms of sea ice in 2023.”

Sea ice extent is the surface area of ice covering an ocean at a given time.

Speaking from the Portuguese capital, Lisbon, Silva provided a sobering regional overview of the heat waves and extreme heat events, which are contributing to record global temperatures.

He observed that July was the warmest on record in Asia, while in Africa, he cited record-breaking temperatures in Morocco as having had “an important impact in terms of human health and deaths.”

He said intense heat waves in southern and southeastern Europe have “caused casualties and severe impacts on health.” At the same time, he pointed out that the fallout of heat waves in North America have been quite severe, noting that on August 1, “more than 160 million people, about half of the United States population, were under heat alert.”

WMO officials say evidence of our rapidly warming planet underscores the urgency of the Call to Action on Extreme Heat initiative launched by United Nations Secretary-General Antonio Guterres July 25.

In issuing this call, the U.N. chief warned that “Earth is becoming hotter and more dangerous for everyone, everywhere” and this was posing an increased threat to “our socio-economic and environmental well-being.”

WMO officials also stressed the importance of adaptation to climate change as a lifesaving measure, noting that recent estimates produced by WMO and the World Health Organization indicate the global scale-up of heat-health-warning systems for 57 countries alone “has the potential to save an estimated 98,000 lives per year.”

WMO Secretary-General Celeste Saulo said bolstering heat early warning systems in line with her agency’s Early Warnings for All Initiative would ensure at-risk populations receive timely alerts so they can take “protective actions.”

But, she emphasized, climate adaptation alone is not enough.

“We need to tackle the root cause and urgently reduce greenhouse gas levels, which remain at record observed levels.”

Great Barrier Reef waters spike to hottest in 400 years, study finds

WASHINGTON — Ocean temperatures in the Great Barrier Reef hit their highest level in 400 years over the past decade, according to researchers who warned that the reef likely won’t survive if planetary warming isn’t stopped.

During that time, between 2016 and 2024, the Great Barrier Reef, the world’s largest coral reef ecosystem and one of the most biodiverse, suffered mass coral bleaching events. That’s when water temperatures get too hot and coral expel the algae that provide them with color and food, and sometimes die. Earlier this year, aerial surveys of over 300 reefs in the system off Australia’s northeast coast found bleaching in shallow water areas spanning two-thirds of the reef, according to Great Barrier Reef Marine Park Authority.

Researchers from Melbourne University and other universities in Australia, in a paper published Wednesday in the journal Nature, were able to compare recent ocean temperatures to historical ones by using coral skeleton samples from the Coral Sea to reconstruct sea surface temperature data from 1618 to 1995. They coupled that with sea surface temperature data from 1900 to 2024.

They observed largely stable temperatures before 1900 and steady warming from January to March from 1960 to 2024. And during five years of coral bleaching in the past decade — during 2016, 2017, 2020, 2022 and 2024 — temperatures in January and March were significantly higher than anything dating back to 1618, researchers found. They used climate models to attribute the warming rate after 1900 to human-caused climate change. The only other year nearly as warm as the mass bleaching years of the past decade was 2004.

“The reef is in danger, and if we don’t divert from our current course, our generation will likely witness the demise of one of those great natural wonders,” said Benjamin Henley, the study’s lead author and a lecturer of sustainable urban management at the University of Melbourne. “If you put all of the evidence together … heat extremes are occurring too often for those corals to effectively adapt and evolve.”

Across the world, reefs are key to seafood production and tourism. Scientists have long said additional loss of coral is likely to be a casualty of future warming as the world approaches the 1.5 degrees Celsius (2.7 degrees Fahrenheit) threshold that countries agreed to try and keep warming under in the 2015 Paris climate agreement.

Even if global warming is kept under the Paris Agreement’s goal, which scientists say Earth is almost guaranteed to cross, 70% to 90% of corals across the globe could be threatened, the study’s authors said. As a result, future coral reefs would likely have less diversity in coral species — which has already been happening as the oceans have grown hotter.

Coral reefs have been evolving over the past quarter century in response to bleaching events like the ones the study’s authors highlighted, said Michael McPhaden, a senior climate scientist at the National Oceanic and Atmospheric Administration who was not involved with the study. But even the most robust coral may soon not be able to withstand the elevated temperatures expected under a warming climate with “the relentless rise in greenhouse gas concentrations in the atmosphere,” he said.

The Great Barrier Reef serves as an economic resource for the region and protects against severe tropical storms.

As more heat-tolerant coral replaces the less heat-tolerant species in the colorful underwater rainbow jungle, McPhaden said there’s “real concern” about the expected extreme loss in the number of species and reduction in area that the world’s largest reef covers.

“It’s the canary in the coal mine in terms of climate change,” McPhaden said.

Drones warn New Yorkers about storm dangers

NEW YORK — Gone is the bullhorn. Instead, New York City emergency management officials have turned high-tech, using drones to warn residents about potential threatening weather.

With a buzzing sound in the background, a drone equipped with a loudspeaker flies over homes warning people who live in basement or ground-floor apartments about impending heavy rains.

“Be prepared to leave your location,” said the voice from the sky in footage released Tuesday by the city’s emergency management agency. “If flooding occurs, do not hesitate.”

About five teams with multiple drones each were deployed to specific neighborhoods prone to flooding. Zach Iscol, the city’s emergency management commissioner, said the messages were being relayed in multiple languages. They were expected to continue until the weather impacted the drone flights.

Flash floods have been deadly for New Yorkers living in basement apartments, which can quickly fill up in a deluge. Eleven people drowned in such homes in 2011 amid rain from the remnants of Hurricane Ida.

The drones are in addition to other forms of emergency messaging, including social media, text alerts and a system that reaches more than 2,000 community-based organizations throughout the city that serve senior citizens, people with disabilities and other groups.

“You know, we live in a bubble, and we have to meet people where they are in notifications so they can be prepared,” New York City Mayor Eric Adams said at a press briefing on Tuesday.

Adams is a self-described “tech geek” whose administration has tapped drone technology to monitor large gatherings as well as to search for sharks on beaches. Under his watch, the city’s police department also briefly toyed with using a robot to patrol the Times Square subway station, and it has sometimes deployed a robotic dog to dangerous scenes, including the Manhattan parking garage that collapsed in 2023.

Musk’s X sues advertisers over alleged ‘massive advertiser boycott’

wichita falls, texas — Elon Musk’s social media platform X has sued a group of advertisers, alleging that a “massive advertiser boycott” deprived the company of billions of dollars in revenue and violated antitrust laws.

The company formerly known as Twitter filed the lawsuit Tuesday in a federal court in Texas against the World Federation of Advertisers and member companies Unilever, Mars, CVS Health and Orsted.

It accused the advertising group’s brand safety initiative, called the Global Alliance for Responsible Media, of helping to coordinate a pause in advertising after Musk bought Twitter for $44 billion in late 2022 and overhauled its staff and policies.

Musk posted about the lawsuit on X on Tuesday, saying “now it is war” after two years of being nice and “getting nothing but empty words.”

X CEO Linda Yaccarino said in a video announcement that the lawsuit stemmed in part from evidence uncovered by the U.S. House Judiciary Committee, which she said showed a “group of companies organized a systematic illegal boycott” against X.

The Republican-led committee had a hearing last month looking at whether current laws are “sufficient to deter anticompetitive collusion in online advertising.”

The lawsuit’s allegations center on the early days of Musk’s Twitter takeover and not a more recent dispute with advertisers that came a year later.

In November 2023, about a year after Musk bought the company, a number of advertisers began fleeing X over concerns about their ads showing up next to pro-Nazi content and hate speech on the site in general, with Musk inflaming tensions with his own posts endorsing an antisemitic conspiracy theory.

Musk later said those fleeing advertisers were engaging in blackmail and, using a profanity, essentially told them to go away.

The Belgium-based World Federation of Advertisers and representatives for CVS, Orsted, Mars and Unilever didn’t immediately respond to requests for comment Tuesday.

A top Unilever executive testified at last month’s congressional hearing, defending the British consumer goods company’s practice of choosing to put ads on platforms that won’t harm its brand.

“Unilever, and Unilever alone, controls our advertising spending,” said prepared written remarks by Herrish Patel, president of Unilever USA. “No platform has a right to our advertising dollar.”

More than 120 people die in Tokyo from heatstroke in July

TOKYO — More than 120 people died of heatstroke in the Tokyo metropolitan area in July, when the nation’s average temperature hit record highs and heat warnings were in effect much of the month, Japanese authorities said Tuesday. 

According to the Tokyo Medical Examiner’s Office, many of the 123 people who died were elderly. All but two were found dead indoors, and most were not using air conditioners despite having them installed. 

Japanese health authorities and weather forecasters repeatedly advised people to stay indoors, consume ample liquids to avoid dehydration, and use air conditioning, because elderly people often think that air conditioning is not good for one’s health and tend to avoid using it. 

It was the largest number of heatstroke deaths in Tokyo’s 23 metropolitan districts in July since 127 deaths were recorded during a 2018 heatwave, the medical examiner’s office said. 

More than 37,000 people were treated at hospitals for heatstroke across Japan from July 1 to July 28, according to the Fire and Disaster Management Agency. 

The average temperature in July was 2.16 degrees Celsius (3.89 degrees Fahrenheit) higher than the average over the past 30 years, making it the hottest July since the Japan Meteorological Agency began keeping records in 1898. 

On Tuesday, heatstroke warnings were in place in much of Tokyo and western Japan. The temperature rose to about 34 C (93 F) in downtown Tokyo, where many people carried parasols or handheld fans. 

“I feel every year the hot period is getting longer,” said Hidehiro Takano from Kyoto. “I have the aircon on all the time, including while I’m sleeping. I try not to go outside.” 

Maxime Picavet, a French tourist, showed a portable fan he bought in Tokyo. “It works very, very well,” he said. “With this temperature, it’s a necessity.” 

The meteorological agency predicted more heat in August, with temperatures of 35 C (95 F) or higher. 

“Please pay attention to temperature forecasts and heatstroke alerts and take adequate precautions to prevent heatstroke,” it said in a statement.
