The Webb Space Telescope is marking one year of cosmic photographs with one of its best yet: the dramatic close-up of dozens of stars at the moment of birth. 

NASA unveiled the latest snapshot Wednesday, revealing 50 baby stars in a cloud complex 390 light-years away. The region is relatively small and quiet yet full of illuminated gases, jets of hydrogen and even dense cocoons of dust with the delicate beginnings of even more stars. 

“Prepare to be awestruck!” NASA Administrator Bill Nelson tweeted, noting that the image “presents star birth as an impressionistic masterpiece.” 

All of the young stars appear to be no bigger than our sun. Scientists said the breathtaking shot provides the best clarity yet of this brief phase of a star’s life. 

“It’s like a glimpse of what our own system would have looked like billions of years ago when it was forming,” NASA program scientist Eric Smith told The Associated Press. 

“I like to remind people that when this light left, it was roughly 1633. … People were putting Galileo on trial for believing that the Earth goes around the sun, and here we are seeing separate suns and planets forming today,” Smith said. 

This cloud complex, known as Rho Ophiuchi, is the closest star-forming region to Earth and is found in the sky near the border of the constellations Ophiuchus and Scorpius, the serpent-bearer and scorpion. With no stars in the foreground of the photo, NASA noted, the details stand out all the more. Some of the stars display shadows indicating possible planets in the making, according to NASA. 

Webb — the largest and most powerful astronomical observatory ever launched into space — has been churning out cosmic beauty shots for the past year. The first pictures from the $10 billion infrared telescope were unveiled last July, six months after its liftoff from French Guiana. 

It’s considered the successor to the Hubble Space Telescope, orbiting Earth for 33 years. A joint NASA-European Space Agency effort, Webb scans the universe from a more distant perch, 1 million miles (1.6 million kilometers) away.

Still ahead for Webb: Astronomers hope to behold the earliest stars and galaxies of the universe while scouring the cosmos for any hints of life.

“We’ve already been using Webb to look at planets around other stars to see if we can analyze their atmospheres to see if they would be capable of hosting life,” Smith said. “We haven’t found one of them yet, but we’re still only one year into the mission.”

The European Medicines Agency (EMA) said on Tuesday it has extended its probe into Novo Nordisk’s diabetes drugs Ozempic and weight-loss treatment Saxenda, following two reports of suicidal thoughts, to include other drugs in the same class.

The agency began its review on July 3 after Iceland’s health regulator flagged the reports of patients thinking about suicide and one case of thoughts of self-harm after use of Novo Nordisk’s drugs.

There have been issues of suicidal thoughts linked to another class of weight-loss drugs, which have hobbled previous attempts by the drug industry to develop lucrative weight-loss drugs.

Sanofi’s weight-loss drug Acomplia, which never won U.S. approval, was withdrawn in Europe in 2008 after being linked to suicidal thoughts.

The EMA said on Tuesday it will investigate the class of drugs known as GLP-1 receptor agonists, which trigger a feeling of fullness after eating. The review is expected to be completed in November, according to the agency.

Drugmaker Eli Lilly’s shares closed down 3.1%. Its diabetes drug Trulicity also belongs to the same class.

Novo Nordisk’s weight-loss drug Wegovy, which contains the active ingredient semaglutide, is also part of the review.

Other GLP-1 drugs include Sanofi’s Suliqua and AstraZeneca’s Bydureon. Both are approved in Europe for treatment of type 2 diabetes.

Sanofi said it has not identified any safety concerns related to “suicidal ideation” from use of its GLP-1 receptor agonist. However, the company has started an investigation and will share all relevant information with the European health regulator.

Eli Lilly and AstraZeneca did not immediately respond to Reuters’ requests for comment.

The European health regulator is also investigating GLP-1 drugs for possible risk of thyroid cancer.

Australian scientists say they have developed a special glue that can be used to repair parts of the World Heritage-listed Great Barrier Reef. Researchers at the Queensland University of Technology believe the biodegradable putty has the potential to help the coral recover after it’s been damaged by cyclones, hit by boats or suffered bleaching.

The Great Barrier Reef is arguably Australia’s most valuable natural treasure. It is the world’s largest coral system and faces an array of threats, including climate change, pollution, over-fishing and coral-eating crown-of-thorns starfish.

When reefs are damaged by cyclones, or struck by boats, patches of rubble are often left behind.

These can be shifted by waves and currents, preventing the formation of a stable seabed that coral needs to grow. Coral bleaching can also cause reefs to disintegrate. When ocean temperatures are too warm – a consequence of climate change – the coral responds to the heat by expelling the algae that give them their brilliant colors and most of their energy. When a coral bleaches, it is not dead, but it becomes far more fragile.

In a bid to reverse some of that degradation, a team at the Queensland University of Technology has made a reef-binding glue that eventually dissolves away.

Leonie Barner is a professor of chemistry at the Queensland University of Technology. She told the Australian Broadcasting Corp. that the glue should be a sustainable way to help reefs recover.

“One component that we are using is actually a plant extract. It’s coming from a natural resource, and the other one is a bio-compatible polymer. So, it has no harmful effects on the marine environment. We have tested that in the lab,” said Barner.

However, applying the adhesive putty to large areas is a major challenge. The Great Barrier Reef runs 2,300 kilometers down Australia’s northeastern coast and spans an area about the size of Japan.

Researchers in Queensland hope that underwater robots could eventually be used to help stick broken pieces of Australia’s Great Barrier Reef and other reefs back together.

In the past, researchers tried dropping metal structures and mesh into the ocean to stabilize coral rubble but their use can permanently alter the reef.

Sea trials of the reef-bonding glue are scheduled to start later this month.

Humanity has etched its way into Earth’s geology, atmosphere and biology with such strength and permanence that a team of scientists figures we have shifted into a new geologic epoch — one of our own creation. It’s called the Anthropocene.

A geologic task force recommends marking this new epoch’s start in the deep, pristine Crawford Lake outside Toronto, Canada, with a “golden spike.” The start of the human epoch is sometime around 1950 to 1954. The specific date will be determined soon, probably by levels of plutonium in new measurements from the bottom of the lake.

“It’s quite clear that the scale of change has intensified unbelievably and that has to be human impact,” said University of Leicester geologist Colin Waters, who chaired the Anthropocene Working Group, which is making the recommendation. “It’s no longer just influencing Earth’s sphere, it’s actually controlling.”

The burning of coal, oil and gas that’s changing Earth’s climate and atmosphere, nuclear bomb detonations spotted in soil around the globe, plastics and nitrogen from fertilizers added on land, and dramatic changes to species that make up the rest of the Earth characterize the new epoch, scientists said.

The idea of the Anthropocene was proposed at a science conference more than 20 years ago by the Nobel Prize-winning chemist Paul Crutzen. Teams of scientists have debated the issue for decades.

A special committee was set up to examine whether the designation was needed, when it would start and where a golden spike would be placed to commemorate the start. Such spikes commemorate new geologic time periods across the Earth.

Distinct and multiple signals starting around 1950 in Crawford Lake show that “the effects of humans overwhelm the Earth system,” said Francine McCarthy, a committee member who specializes in that site as an Earth sciences professor at Brock University in Canada.

Because Crawford Lake is 24 meters (79 feet) deep but just under 2,400 square meters (25,800 square feet) in area, the layers on the lake bottom are pristine, showing what’s in the air and on Earth each year, scientists said.

“The remarkably preserved annual record of deposition in Crawford Lake is truly amazing,” said U.S. National Academies of Sciences President Marcia McNutt, who is not part of the committee. “It is just as important to the beginning of an era dominated by one category of Earth species as it is to mark the end.”

The Anthropocene — derived from the Greek terms for “human” and “new” — shows the power and the hubris of humankind, several scientists told The Associated Press.

“The hubris is in imagining that we are in control,” former U.S. White House science adviser John Holdren, who was not part of the working group of scientists and disagrees with its proposed start date, suggesting it should be much earlier. “The reality is that our power to transform the environment has far exceeded our understanding of the consequences and our capacity to change course.”

Jurgen Renn, who directs the Max Planck Institute for the History of Science in Berlin and was not part of the study group, said humans also “need that power, our knowledge, our technologies, but also our capacities of making better societies” to lessen and adapt to the worst consequences of our actions.

This puts the power of humans in a somewhat similar class with the meteorite that crashed into Earth 66 million years ago killing off dinosaurs, starting the Cenozoic Era and what is sometimes called the age of mammals. But that meteorite started a whole new era, and scientists are now proposing humans started a new epoch, which is a much smaller geologic time period.

Geologists measure time in eons, eras, periods, epochs and ages. They propose we have moved from the Holocene Epoch, which started about 11,700 years ago at the end of an ice age, to the Anthropocene Epoch.

It also starts a new age. It’s named Crawfordian, after the lake chosen as the starting point, and ends the Meghalayan Age that started 4,200 years ago, Waters said.

The proposal needs to be approved by three different groups of geologists and will ultimately need to be signed off at during a major conference next year.

The reason geologists didn’t make it a bigger time period change is that the current Quaternary Period is based on permanent ice on Earth’s poles, which still exists. But in a few hundred years, if climate change continues and those disappear, it may be time to change that, Waters said.

“If you know your Greek tragedies, you know power, hubris and tragedy go hand in hand,” said Harvard science historian Naomi Oreskes, a working group member. “If we don’t address the harmful aspects of human activities, most obviously disruptive climate change, we are headed for tragedy.”

India will launch a mission to the moon later this week hoping to become the fourth country to land a craft on the lunar surface.    

So far only three countries — the United States, Russia and China — have achieved what is called a “soft landing” on the moon in which vehicles touch down without damage.  

The mission marks the Indian Space Research Organization’s (ISRO) second attempt to land a rover on the moon — a previous effort nearly four years ago failed.    

The spacecraft called Chandrayaan-3, which means moon vehicle in Sanskrit, is scheduled to be launched Friday afternoon (2:35 p.m. Indian time) It is equipped with a lander and a robotic rover that are expected to land on the moon on August 23 or August 24 to map the lunar surface for about two weeks. 

“The date is decided based on when the sunrise is on the moon; it will depend on the calculations, but if it gets delayed, then we will have to keep the landing for the next month in September,” ISRO director S. Somanath said.  

He said the main objective is to demonstrate “a safe and soft landing.”  

India aims to land its rover on the South Pole of the moon, a previously unexplored part that lies in near darkness. It will study the topography of this region.   

“There is expectation that the southern parts of the moon have a lot of mineral deposits and helium-3. There is also the possibility of water deposits there,” Ajey Lele, a space consultant with the Manohar Parrikar Institute for Defense Studies and Analyses in New Delhi told VOA.  

Through such studies of the moon’s topography, India’s upcoming space flight to the moon “has the potential to contribute to scientific understanding that will underpin a variety of future lunar missions, including those by other actors,” Tomas Hrozensky at the European Space Policy Institute told VOA in emailed comments.  

India’s moon mission in 2019 had successfully deployed a lunar orbiter, but the lander crashed during the final moments of its descent to the lunar surface — a setback to its main goal.   

Aiming for ‘soft’ landing

Lele says there is optimism about Chandrayaan-3 achieving a “soft” landing. “The glitches that led to the failure of the previous mission have been fixed. Basically, they have made the lander system more sturdy, so it can withstand any impact.” 

The latest space project is part of India’s ambitions to showcase its homegrown technological capabilities in space and be seen as a leading space-faring nation.   

“After a quantum rise in our space expertise, India can no longer wait to be left behind in the march to the moon,” India’s space minister, Jitendra Singh, said Sunday.  

India’s space program has notched several milestones. Its first mission to the moon in 2008 helped confirm the presence of water. In 2013, it put a satellite in orbit around Mars. Its space agency is also preparing for its most ambitious space mission yet — a human spaceflight next year.   

Delivering on “an ambitious and technologically challenging vision serves a profound benefit for perception of the government’s capability both within and outside of the country,” according to Hrozensky. 

US, India teaming up

In recent years there has been a renewed interest in exploring the moon as scientists seek to determine whether it will be possible to mine the moon for minerals and other resources that are shrinking on earth.  

Outer space is one of the areas in which India and the U.S. decided to deepen collaboration during Indian Prime Minister Narendra Modi’s visit to Washington last month. U.S. President Joe Biden said that the two countries are joining hands to send an Indian astronaut to the International Space Station next year.  

India has also signed on to the Artemis Accords, an American-led international partnership for space cooperation that, among other objectives, aims to send humans to the Moon by 2025 after a gap of five decades.

Astronomers have discovered the most distant black hole yet using NASA’s Webb Space Telescope, but that record isn’t expected to last.

The black hole is at the center of a galaxy created a mere 570 million years after the Big Bang. That’s 100 million years closer to the beginning of the cosmos than a black hole identified in 2021 by a Chinese team using a telescope in Chile.

Webb already has spotted other black holes that appear to be even closer to the Big Bang nearly 14 billion years ago, but those findings are still under review, said University of Texas at Austin astronomer Steven Finkelstein, one of the lead researchers. The finding has been accepted for publication by The Astrophysical Journal Letters.

Because the signals from this particular black hole are weak, more observations are needed, according to the Texas-led team.

There are untold numbers of dormant black holes, some even more distant than this one. But without any glowing gas, they are invisible, Finkelstein said.

Detected in February, this particular one is active and actually puny as black holes go — equivalent to about 9 million times the mass of our sun. That’s close in size to the one in our own Milky Way galaxy, according to the team.

Using Webb, the team also spotted two other small black holes from the early universe, dating to around 1 billion years after the Big Bang. The observations suggest that these downsized versions may have been more common than previously thought as the cosmos took shape.

“There are probably many more hidden little monsters out there waiting to be found,” Colby College’s Dale Kocevski, who was part of the team, said in an email.

Launched in late 2021, Webb is the largest, most powerful telescope ever sent into space. Its first images and science results were released by NASA with much fanfare a year ago this week.

Scientists say crushing temperatures that blanketed Europe last summer may have led to more than 61,000 heat-related deaths, highlighting the need for governments to address the health impacts of global warming.

In their study, published Monday in the journal Nature Medicine, researchers examined official mortality figures from 35 European countries and found a marked increase in deaths between late May and early September last year compared with the average recorded over a 30-year period.

The increase in heat-related deaths was higher among older people, women and in Mediterranean countries, they found. But the data also indicated that measures taken in France since a deadly heat wave two decades ago may have helped prevent deaths there last year. 

“In the pattern of summer mean temperatures in Europe during the summer of 2022, we don’t see borders,” said co-author Joan Ballester of the Barcelona Institute for Global Health. The highest temperatures were recorded across a swath of southwestern Europe, from Spain to France and Italy.

“But when we look at the heat-related mortality, we start to see borders,” Ballester told The Associated Press. While France had 73 heat-related deaths per million inhabitants last summer, Spain’s rate was 237 and Italy’s was 295, the study found.

“Possibly France drew lessons from the experience of 2003,” he said.

France’s warning system includes public announcements with advice on how to stay cool and encouraging people to drink water and avoid alcohol.

Not all of the heat-related deaths calculated across Europe last summer were linked to climate change. Some would have occurred even if summer temperatures had stayed in line with the long-term average. But there is no doubt that the intense heat in 2022 — which saw numerous European records tumble — led to higher mortality rates, as other studies on heat deaths have also shown.

The authors calculated that there were over 25,000 more heat-related deaths last summer than the average from 2015 to 2021.

Without appropriate prevention measures, “we would expect a heat-related mortality burden of 68,116 deaths on average every summer by the year 2030,” the authors said. They forecast that figure would rise to over 94,000 by 2040 and more than 120,000 by mid-century.

Governments in Spain and Germany recently announced new measures to address the effects of hot weather on their populations. In Switzerland, a group of seniors is citing the danger posed to older women by intense heat in a court case seeking to force the government to take tougher climate action.

One difficulty for researchers is that heat-related deaths are often happening in people with pre-existing conditions, such as cardiovascular disease, said Matthias an der Heiden of Germany’s Robert Koch Institute, who was not involved in the study. 

In such cases, the heat is not the underlying cause of death and therefore not recorded in the cause of deaths statistics. This can cloak the significant impact that heat has on vulnerable people, with up to 30% more deaths in certain age groups during periods of hot weather.

“The problem is going to get more acute due to climate change and medical systems need to adjust to that,” he said.

An der Heiden also noted that the Nature study estimated almost double the number of heat deaths in Germany last year than his institute. While the discrepancy can be explained by the different threshold values for heat used, it indicates the need for a more detailed description of heat-related mortality that distinguishes between moderate and intensive heat, he said.

According to co-author Ballester, the impact of heat depends greatly on the overall health of the population, particularly with regard to heart and lung disease.

Other measures, already being implemented in countries such as France, include raising awareness about the dangers of high temperatures and identifying individuals who need special attention during heat waves, he said.

“These are cheap, cost-effective measures,” said Ballester.

He dismissed the suggestion that rising temperatures around the globe could, on balance, be beneficial due to fewer deaths during the winter months, noting the manifold risks posed to human civilization by rapid climatic change.

“In my opinion and the opinion of all the climate scientists, the less the climate is modified, the better,” said Ballester. “That’s why it’s so important that we start, as soon as possible, mitigating climate change and reducing vulnerability.”

Meta Platforms’ Twitter rival Threads crossed 100 million sign-ups within five days of launch, CEO Mark Zuckerberg said on Monday, dethroning ChatGPT as the fastest-growing online platform to hit the milestone. 

Threads has been setting records for user growth since its launch on Wednesday, with celebrities, politicians and other newsmakers joining the platform seen by analysts as the first serious threat to the Elon Musk-owned microblogging app. 

“That’s mostly organic demand, and we haven’t even turned on many promotions yet,” Zuckerberg said in a Threads post announcing the milestone. 

The app’s sprint to 100 million users was much speedier than that of OpenAI-owned ChatGPT, which became the fastest-growing consumer application in history in January about two months after its launch, according to a UBS study. 

Still, Threads has some catching up to do. Twitter had nearly 240 million monetizable daily active users as of July last year, according to the company’s last public disclosure before Musk’s takeover. 

Twitter has responded to Threads’ arrival by threatening to sue Meta, alleging that the social media behemoth used its trade secrets and other confidential information to build the app. 

That claim, legal experts say, could be hard to prove. 

Threads bears a strong resemblance to Twitter, as do numerous other social media sites that have cropped up in recent months as users have chafed at Musk’s management of the service. It allows posts that are up to 500 characters long and supports links, photos and videos of up to 5 minutes. 

The app also does not yet have a direct messaging function and lacks a desktop version that certain users, such as business organizations, rely on. 

It also currently lacks hashtags and keyword search functions, which limits both its appeal to advertisers and its utility as a place for following real-time events like users frequently do on Twitter. 

Still, analysts said the turmoil at Twitter, including recently imposed limits on the number on tweets users can see, could help Threads to attract users and advertisers.  

Currently, there are no ads on the Threads app and Zuckerberg said the company would only think about monetization once there was a clear path to 1 billion users. 

Instagram head Adam Mosseri said last week Meta was not trying to replace Twitter and that Threads aimed to focus on light subjects like sports, music, fashion and design.  

He acknowledged that politics and hard news are inevitably going to show up on Threads, in what would be a challenge for the app pitching itself as the “friendly” option for public discourse online.

Health officials are reporting a deadly outbreak of cholera in the South African province of Gauteng.

Authorities say nearly 50 people have died, with most of the deaths concentrated in the Hammanskraal area. Cases have been reported in other areas as well.

Medical officials have urged residents to be vigilant about what they consume and to practice good hygiene, like hand washing.

Cholera mainly spreads through contaminated water or food.

Symptoms include diarrhea, vomiting and dehydration.

Two years after Brazil began emerging from its pandemic horror show thanks to a massive immunization campaign, officials face a paradoxical predicament: vaccination rates have plunged, and not just for COVID-19. 

The troubling trend has left millions exposed to once-eradicated diseases.    

Doctors, public officials and UNICEF have sounded the alarm over collapsing immunization rates in Brazil, where overall vaccination coverage has fallen from an impressive 95% in 2015 to just 68% last year, according to official figures.  

For polio, the figure fell from 85% to 68%, triggering warnings that the disease could make a comeback in Brazil, where it was eradicated in 1989.  

The figures are similar for other vaccines, allowing diseases to spread. Measles, officially eliminated in Brazil in 2016, returned two years later. There are fears diphtheria is making a resurgence, too.  

Health experts say vaccine hesitancy is a growing problem worldwide. But it is particularly worrying in Brazil, a sprawling country of 203 million people that until recently was hailed as a champion of mass vaccination drives.    

Then an anti-vax movement started spreading around 2016, soon gaining outsize influence via a powerful ally: far-right leader Jair Bolsonaro, president from 2019 to 2022, who refused to be vaccinated against COVID-19, joking the jab could “turn you into an alligator.”    

“It’s very sad to see how a country whose vaccination programs set an example for the world can suddenly suffer from an anti-vaccine movement,” Natalia Pasternak, head of the Question of Science Institute (IQC), a public policy think tank, told AFP.   

“It’s very sad to see how 50 years of work can be so easily destroyed in three.” 

Hope after haunting images

COVID-19 highlighted the shots-in-arms capacities of Brazil’s struggling but lauded universal public health system.  

Back in 2020, some of the most haunting images of the pandemic were of mass graves and corpses piled in refrigerator trucks in places such as Manaus, in northern Brazil, whose overwhelmed hospitals ran out of oxygen.  

Then new images started emerging in 2021, of public health workers turning Rio de Janeiro’s carnival parade venue into a drive-through immunization center or boating deep into the Amazon rainforest to administer vaccines in Indigenous villages.  

Experts credit the campaign’s success with stopping a far bigger tragedy in Brazil, where more than 700,000 people have died of COVID-19, second only to the United States.  

Despite a slow start — widely blamed on Bolsonaro — Brazil had by early last year vaccinated 93% of adults against COVID-19.  

Then rates fell, not only for COVID-19 vaccines but across the board. 

‘The infodemic’ 

Many factors are driving the decline, experts say.   

They include failure to catch up on vaccines delayed during the pandemic, inaccessible health care and declining awareness of the dangers of once-ubiquitous diseases.  

But experts say a new element is making things much worse: the toxic mix of politics, polarization and disinformation that exploded during the pandemic and is increasingly familiar worldwide.  

In Brazil, despite Bolsonaro losing a divisive 2022 election to veteran leftist Luiz Inacio Lula da Silva, the anti-vax movement still thrives.  

“We’re facing a post-trust scenario, in which families are being attacked by disinformation and lies. It’s not just the occasional fake news story, it’s very structured,” said Isabella Ballalai of the Brazilian Immunization Society. “The consequences of that ‘infodemic’ will be worse than the pandemic itself.”  

Brazilian Health Minister Nisia Trindade says the government is evaluating how to punish doctors spreading anti-vax disinformation.  

“Criminal fake news is sowing doubt and fueling vaccine hesitancy,” she told AFP.    

Going local  

A recent survey by the Brazilian Pediatrics Society (SBP) and IQC found that doctors said parents’ most common reasons for not vaccinating their children were fears of side effects and mistrust of vaccines.  

Experts say health workers are desperate for reliable information to counter the flood of anti-vax disinformation.    

Pasternak, whose organization is working on creating just that, says health officials also need to think locally.  

“Studies show the best way to convince people to get vaccinated is working with local leaders … People listen to those they trust: pastors, community leaders,” she said.  

But reversing the trend will not be easy, Pasternak admitted. “We have lots of work to do.”

One person is dead and three missing in landslides in southwestern Japan, authorities said Monday, as the country’s weather agency warned of the “heaviest rain ever” in the region. 

A 77-year-old woman was confirmed dead in a landslide that entered her home overnight in rural Fukuoka, the local fire department told AFP. 

Her husband was recovered conscious and taken to hospital. 

Three people were also missing after a landslide in Karatsu City, in Saga prefecture, which neighbors Fukuoka, local authorities there said. 

The Japan Meteorological Agency urged people to take shelter as the heavy downpours risked flooding and landslides across the Fukuoka and Oita regions. 

“A special heavy rain warning has been issued for municipalities in Fukuoka Prefecture. This is the heaviest rain ever experienced” by the region, Satoshi Sugimoto of the JMA’s forecast division told reporters. 

“There is a very high possibility that some kind of disaster has already occurred. … The situation is such that lives are in danger and safety must be secured,” he added. 

Noncompulsory evacuation orders were issued to parts of Fukuoka, Oita and neigboring prefectures, which were opening shelters to accommodate those leaving their homes.

The prime minister’s office said a taskforce had been established to coordinate a response to the rains. 

The downpour forced the stoppage of bullet train service between western Hiroshima and Fukuoka, operator JR West said.

Japan is currently in its annual rainy season, which often brings heavy downpours, and sometimes results in flooding and landslides, as well as casualties.   

Scientists say climate change is intensifying the risk of heavy rain in Japan and elsewhere, because a warmer atmosphere holds more water. 

In 2021, rain triggered a devastating landslide in the central resort town of Atami that killed 27 people. 

And in 2018, floods and landslides killed more than 200 people in western Japan during the rainy season.

Natural disasters can be dramatic — barreling hurricanes, building-toppling tornadoes — but heat is more deadly.

Chicago learned that the hard way in 1995.

That July, a weeklong heat wave that hit 106 degrees Fahrenheit (41 degrees Celsius) killed more than 700 people. Most of the deaths occurred in poor and majority Black neighborhoods, where many elderly or isolated people suffered without proper ventilation or air conditioning. Power outages from an overwhelmed grid made it all worse.

Initially slow to react, Chicago has since developed emergency heat response plans that include a massive push to alert the public and then connect the most vulnerable to the help they may need. Other cities like Los Angeles, Miami and Phoenix now have “chief heat officers” to coordinate planning and response for dangerous heat. Around the world, cities and countries have adopted similar measures.

But experts warn those steps might not be enough in a world that is seeing heat records consistently shatter and with continuing inequality in who is most vulnerable.

“I don’t know a single city that is truly prepared for the worst-case scenario that some climate scientists fear,” said Eric Klinenberg, a professor of social sciences at New York University who wrote a book about the Chicago heat wave.

Heat preparedness has generally improved over the years as forecasting has become more accurate, and as meteorologists, journalists and government officials have focused on spreading the word of upcoming danger. Chicago, for example, has expanded its emergency text and email notification system and identified its most vulnerable residents for outreach.

But what works in one city might not be as effective in another. That’s because each has its own unique architecture, transportation, layout and inequities, said Bharat Venkat, an associate professor at UCLA who directs the university’s Heat Lab, aimed at tackling what he calls “thermal inequality.”

Venkat thinks cities should address inequality by investing in labor rights, sustainable development and more. That may sound expensive — who pays, for instance, when a city tries to improve conditions for workers in blistering food trucks? — but Venkat thinks doing nothing will ultimately cost more.

“The status quo is actually deeply expensive,” he said. “We just don’t do the math.”

France launched a heat watch warning system after an extended heat wave in 2003 was estimated to have caused 15,000 deaths — many of them older people in city apartments and homes without air conditioning. The system includes public announcements urging people to hydrate. Just last month, Germany launched a new campaign against heatwave deaths that it said was inspired by France’s experience.

In India, a powerful heat wave in 2010 with temperatures over 118 degrees Fahrenheit (48 degrees Celsius) led to the deaths of over 1,300 people in the city of Ahmedabad. City officials now have a heat action plan to improve awareness among the local population and health care staff.  

Ladd Keith, an assistant professor at the University of Arizona, cited Baltimore’s Code Red Extreme Heat alerts as an example of a well-designed alert system. The alerts go out when the forecast calls for a heat index of 105 Fahrenheit or higher, and sets in motion things like more social services in communities most vulnerable to heat risks.

He lauded the heat officers in cities like Los Angeles, Miami and Phoenix, but said there are “still over 19,000 cities and towns without them.”

Inkyu Han, an environmental health scientist at Temple University in Philadelphia, noted that cities are still struggling to get aids such as cooling centers and subsidized air conditioning into poorer neighborhoods. He said more can be done, too, with simple and sustainable solutions such as improving tree canopy.

“Notably, low-income neighborhoods and communities of color in Philadelphia often lack street trees and green spaces,” Han said.

In Providence, Rhode Island, the Atlantic Ocean typically moderates temperatures, but the region can still get heat waves. Kate Moretti, an emergency room physician, said the city’s hospitals see more patients when the heat strikes — with increases in illnesses that may not be obviously related to heat, like heart attacks, kidney failure and mental health problems.

“We definitely notice that it puts a strain on the system,” Moretti said. Older people, people who work outdoors, people with disabilities and people who are homeless make up a big share of those admissions, she said.

Miami — considered ground zero for the climate change threat due to its vulnerability to sea level rise, flooding, hurricanes and extreme heat — appointed its heat officer two years ago to develop strategies to keep people safe from the heat.

Robin Bachin, an associate professor of civic and community engagement at the University of Miami, noted that the federal government has laws to protect people in cold climates from having their heat shut off in dangerous conditions, but doesn’t have something similar for cooling.

“For people in apartments that are not publicly subsidized, there is no requirement for landlords to provide air conditioning,” Bachin said. “That’s incredibly dangerous to particularly our local low-income population, let alone people who are unhoused or are outdoor workers.”

Klinenberg said that the United States has so far gotten lucky with the duration of most heat waves, but that electrical grids vulnerable to high demand in some regions, along with persistent social inequities, could spell serious trouble in the coming decades.

That’s partly because the underlying social problems that make heat events so deadly are only getting worse, Klinenberg said. Chicago’s 1995 deaths were clustered not only in poor and segregated neighborhoods, but also specifically within what he calls “depleted” neighborhoods, places where it’s harder for people to gather and where social connections have been worn thin. Empty lots, abandoned restaurants and poorly maintained parks mean that people are less likely to check up on each other.

RIO DE JANEIRO — Brazil’s President Luiz Inácio Lula da Silva met Saturday with his Colombian counterpart, Gustavo Petro, to build momentum for an upcoming regional summit on the Amazon rainforest and enhance efforts for its protection.

The meeting took place in Colombia’s Leticia, a town in the Amazon’s triple border region between Colombia, Brazil and Peru, where organized crime has recently increased its hold.

The meeting aimed to lay groundwork for the Amazon Summit that the Brazilian government is organizing in Belem next month. That summit will be attended by leaders of the countries that are party to the Amazon Cooperation Treaty Organization: Bolivia, Brazil, Colombia, Ecuador, Guyana, Peru, Suriname, and Venezuela.

Lula is pushing for a joint declaration from the summit, which would be presented at the United Nation’s climate conference, known as COP28, in Dubai in November.

“We will have to demand together that rich countries fulfil their commitments,” Lula said in Leticia, sitting next to Petro.

Petro also stressed the need for a common front to exert pressure on developed countries.

“We believed that progress was the destruction of trees. … Today that is nothing other than the destruction of life,” he said.

The Colombian leader said tackling the climate crisis will require spending trillions of dollars. This could be achieved by transforming the global debt system and “trading debt for climate action,” he said.

The final document will comprise measures for the sustainable development of the Amazon, protecting the biome, and promoting social inclusion, science, technology and innovation while valuing Indigenous peoples and their knowledge, Brazil’s presidential palace said in a statement.

“Joint action of the countries that share the Amazon biome is fundamental for facing the multiple challenges in the region,” the statement said.

One challenge is the tightened grip of organized crime, particularly in tri-border regions like where Leticia is located. British journalist Dom Phillips and Indigenous activist Bruno Pereira were killed in the neighboring Javari valley region last year.

These areas have become violent hotspots, according to a report by the U.N. Office on Drugs and Crime released in June. It noted criminal groups are simultaneously engaged in cocaine trafficking, as well as natural resource exploitation.

Indigenous groups are disproportionately affected by the criminal nexus in the Amazon, the report added, pointing to forced displacements, mercury poisoning and other health-related impacts as well as increased exposure to violence.

In 2019, Colombia, Bolivia, Ecuador, Brazil, Peru, Guyana and Suriname signed the Leticia Pact to strengthen coordinated actions for the preservation of the natural resources of the Amazon.

But the goals are vague and lack ways to measure progress, said Marcio Astrini, executive secretary of the Climate Observatory, an umbrella organization of environmental groups.

Since taking office in January, Lula has strived to put environmental protection and respect for Indigenous peoples’ rights at the heart of his third term. He successful pursued resumption of international donations for the Amazon Fund that combats deforestation, launched a military campaign to eject illegal miners from Yanomami territory, committed to ending all illegal deforestation by 2030 and restarted the demarcation of Indigenous areas.

Petro has also been vocal about the need to halt destruction in the Amazon. The Colombian leader has proposed the creation of multilateral 20-year financing fund to support farming communities contributing to deforestation. The idea is to compensate them for conservation and regenerative activities instead.

Historically, collaboration between Brazil and Colombia, which share a border longer than 1,500 kilometers, has been lacking, according to Wagner Ribeiro, a geographer and expert in environmental policy from the University of Sao Paulo.

“We hope that opportunities for academic cooperation will arise from the meeting, which will later generate public policies that promote environmental conservation,” Ribeiro said.
