Greenland is melting, the Alps are melting and the Himalayas are melting -- yet in one vast mountain region, huge glaciers have remained stable, or even gained mass, in recent decades. Can it last?

To find out, a dozen scientists, accompanied exclusively by an AFP photographer, trekked high over one glacier in eastern Tajikistan to drill for ice cores -- ancient, deep samples that can shed precious light on climate change.

In September and October, they first spent four days crossing the country from west to east in four-wheel drives, then climbed on foot to over 5,800 meters altitude on the Kon-Chukurbashi ice cap, near the Chinese border.

Camping for a week at the summit, in freezing temperatures and despite a day-long blizzard, the scientists from Switzerland, Japan, the United States and Tajikistan drilled the glacier to extract two 105-metre-long ice cores, in sections.

These layers of ice, compacted over centuries, perhaps millennia, form an archive of climate indicators, yielding data on past snowfall, temperatures, atmosphere and dust.

They must now be analyzed in a laboratory to reveal their dates, said the leader of the team, Evan Miles, a glaciologist affiliated with the universities of Fribourg and Zurich.

"We're hopeful for a truly unique core, not just for the region, but for the broader region actually, probably extending back 20 to 25 or 30,000 years."

The apparently resistant glaciers are spread over thousands of kilometers of high mountain ranges in Central Asia, including Karakoram, Tian Shan, Kun Lun and the Pamir mountains of Tajikistan.

By delving back in time in the ice there, researchers hope to find out why these glaciers have resisted the general planetary warming of recent decades -- and whether this so-called "Karakoram anomaly" could be ending.

"This whole region is globally unique because over the last 25 years, these glaciers have shown very, very limited mass loss and even mass gain," said Miles.

The glaciers have shown some limited signs of loss in recent years, but scientists want to determine whether this is a natural variation or the beginning of a real decline.

"In order to understand that, we really, really need to have a longer time period of records of both temperature and precipitation at the glacier sites," said Miles.

"That's the type of information that an ice core can tell us."

One core will be sent to Japan for analysis and another stored in an underground sanctuary in Antarctica at minus 50C.

That naturally cold storage site is a project of the Ice Memory Foundation, which supported the Tajikistan expedition along with main funder, the Swiss Polar Institute.

The foundation, created in 2021 by French, Italian and Swiss universities and research centers, has already collected several cores in the Alps, Greenland, the Andes and elsewhere.

Future scientists will "be able to analyze (them) with their most modern analytical tools in 50, 100, 200 years and extract new information", said Ice Memory's president Thomas Stocker.

"We will probably lose 90 percent of our glacier mass on the Earth," Stocker told AFP. "So we are trying to help preserve a thing that is threatened by human action."

The scientists were scheduled to review their mission during a news conference in the Tajik capital Dushanbe on Monday.



Algae Fed by Farm Waste Carpet Italy's Warm River Po

Rowers on the River Po in Turin are battling vast blooms of algae, as high temperatures in northwest Italy and runoff from farms create ideal conditions for rampant plant growth.

"Look at these (plants), if you put your oar in, they wouldn't let it go," rowing coach Roberto Romanini told AFP, as four rowers struggled in their boat through a patch of green slime.

Sitting between the Alpine chain on one side and hills on the other, heavily urbanized Turin has suffered soaring temperatures this summer, as heat waves rendered more intense by man-made climate change have gripped Italy.

And the Po, Italy's longest river, is struggling.

It has experienced a significant decline in flow, down 50 percent on its yearly average, due to low rainfall and persistently high temperatures in June and July.

Despite that, dozens of plant species have been blooming since May.

"It looks like a meadow," 60-year-old Romanini said, adding he had "never seen anything like it."

Tearing tangled plants off his motor boat's propeller, he noted, "The river is changing, the climate is changing.”

At the dyke that has controlled the river's level since the 19th century, a thick layer of algae trapped various bottles and a shoe.

Local species such Spirogyra, known as mermaid's tresses, and the blanket weed Cladophora, mingle with the invasive Blitum nuttallianum -- or Nuttall's povertyweed, which is native to North America.

Further upstream, herons have nested under the historic stone Isabella Bridge, and their chicks are taking advantage of the thick layer of vegetation to learn how to walk.

Algae have always been present in the Po, but climate change "makes these phenomena more extreme", said Turin Deputy Mayor Francesco Tresso, calling this year's proliferation "quite exceptional.”

"It's no longer really a river, but rather a warm lake," reaching temperatures of 28 degrees Celsius even though it originates in the nearby Alps, he told AFP.

"Agricultural nutrients from livestock farms are also dumped throughout the basin, which means that plants find an ideal environment here to thrive," he said.

Alice de Marco, the local head of environmental organization Legambiente, said the algae blooms were encouraged "above all by excess nutrients" from farms.

She said a large part of the solution would be "limiting, reducing, or even eliminating the use of pesticides in agriculture.”

This mass of vegetation "has an impact on the food chain -- it reduces the oxygen level underwater, affecting other plants and animals," she said.

Algae have also invaded Lake Iseo in neighboring Lombardy this summer, as well as further afield, from canals in France to the Ebro River in Zaragoza, Spain.

Turin wants to make the Po one of its starring attractions: two river shuttles are scheduled to resume service in 2027 and the city council has renovated a large park next to the river.

But first it needs to get rid of the green weeds.

Near Turin's mock medieval village, an excavator perched on a barge pulls up clumps of dripping algae.

A truck comes every morning to collect the plants, which are then turned into compost. More than 150 tons have been removed in three weeks, at a cost of approximately 100,000 euros ($115,000).

Secondo Barbero, director of the Piedmont Environmental Protection Agency, noted that there is a correct way to remove it.

"The plant shouldn't be cut but uprooted; otherwise, the cut parts can generate new plants," while also contaminating downstream riverbanks, he said.

The growth should slow with the drop in temperatures in autumn, but the city should prepare for a fresh round in spring, Barbero said.

Rower Romanini said that, for now, locals will just have to learn to live with it -- "and show more respect for the river."

Heat at all hours, even in the middle of the night. Long stretches without electricity, meaning some homes can't even use basic fans. And a constant search for relief, like being hosed down with water or sleeping outside.

For many residents of Banda, a town in northern India that has recorded some of the country's highest temperatures, just getting through each day is a challenge.

Global warming, caused mostly by the burning of fuels like gas, oil and coal, is making heat waves across India more frequent and intense. Uttar Pradesh, the state Banda is in, is among those most vulnerable to extreme heat. In 2023, at least 119 people died over several days during a severe heat wave in parts of the state.

In May, temperatures reached 48.2 Celsius (118.8 Fahrenheit), one of multiple times this year that the town recorded the country’s highest temperature for the day. Banda was also the hottest spot on Earth seven times this year, most of them in April, according to climatologist and weather historian Maximiliano Herrera, who tracks global weather extremes. Since then, temperatures have dropped some but are still stifling, particularly as seasonal rains increase humidity.

In June, an Associated Press team went to Banda to report on how people try to cope with the heat throughout the day.

Morning: Heat makes market workers’ jobs tougher Munni Devi and her four sons begin work loading and unloading vegetables when most of the town is asleep.

It’s only 4 a.m., but the temperature is already 30 C (86 F). Workers at Banda's vegetable market are busy unloading tomatoes, jackfruits and other vegetables and transferring them to smaller vehicles for delivery to neighborhood shops.

Devi, 70, says the heat is becoming more intense every year, and this year has been especially bad. The work is physically demanding in any weather. During a heat wave, it can be brutal. But Devi says she and her sons can’t afford to miss a day.

“Everyone feels the heat, but because of our circumstances, we have to bear it,” she says.

At the market, young men wheel carts through narrow lanes. Women sort vegetables on the streets. Devi says many buyers arrive early, hoping to finish shopping before temperatures soar.

Devi and her sons work from early morning until lunch, then return home to recuperate.
She says unreliable power to her home means there is little respite even there. Devi’s grandchildren get sprayed down every day with a water hose to get some relief.

“If there is no power, even the ceiling fans don’t work. Sometimes there is no power for hours,” she says.

Afternoon: Animal lover tries to protect birds from heat impacts As the afternoon sun bakes Banda’s streets, residents who can afford to stay inside do so. But some vegetable sellers and auto rickshaw drivers stay outdoors in hopes of attracting a little more business.

Meanwhile, 70-year-old animal lover Shobharam Kashyap is busy making wooden birdhouses at a workshop in his home.

Kashyap says he and other volunteers have installed over 15,000 birdhouses across the town to give birds respite from an increasingly harsh environment.

Kashyap’s brightly painted birdhouses — many of which are painted green as he says birds seem to prefer that color — have been mounted on trees and walls across Banda.

He has also placed clay water bowls in and near his home to give birds a place for a dip or drink.

Kashyap says he is continuing traditional practices of caring for other animals.

“Our culture has long encouraged feeding birds. Women visiting temples traditionally offer rice. Neither the priest nor the deity consumes it — the birds do,” he says.

Evening: As heat increases, so do hospital admissions Hotter days have brought more patients to the hospital in Banda, one of the bigger medical centers in this region. Those with heat maladies, ranging from fainting to heatstroke, tend to come in the afternoon and evening, filling the corridors and wards.

Patients sit shoulder-to-shoulder on benches. Relatives fan family members with sheets of paper. Hospital staff move between beds carrying intravenous fluids.

Dr. Abhishek Pranayami, the hospital's head doctor, says the hospital sees a surge of patients every summer, "and the number of patients is increasing every year.”

He says they are treating large numbers of people suffering from dehydration, diarrhea, vomiting and abdominal pain — illnesses that become more common as temperatures rise. Some patients recover within days. Others take longer.

“Pressure is quite high on us and the staff,” he says.

Night: Sleeping outdoors or in a rail station to seek a break from heat Even after sunset, Banda remains hot.

When young boys play a game of cricket, they keep their water bottles cool by wrapping them in torn clothes.

At the town’s railway station, families sometimes gather late into the night, hoping the open platforms and occasional breeze will be more comfortable than cramped homes that have absorbed heat all day.

On one such night, dozens are sleeping in the station to avoid the heat. In one spot, several children and adults sleep on blankets spread out on the stone platform with parked train cars a few feet away. Some use bags as pillows. A pile of flip-flops sits inches from their bare feet. Another man stretches out on a bench, with his head on a backpack.

Nearby, several men and women are trying to sleep on blankets near the ticket kiosks, despite the bright lights. Dogs lie between some of the people on the ground, also trying to get relief.

Laborers whose homes are too small and hot to sleep in are sleeping on blankets outside the railway station's entrance, trying their best to get some rest in the hot night. Regardless of the noise of vehicles and passengers entering and leaving the station, laborers and residents are lying on towels and sometimes right on the gravel as the relatively open, breezy roads and pavements near the railway station give them the best chance for some shut-eye.

For parents with little children, the hot night is too uncomfortable for sleep, so they wait in the station, huddled around a smartphone.

The struggle for relief and rest has become a defining feature of summer in cities like Banda.

“Climate change is shifting the average,” says Abhiyant Tiwari, climate and health expert at New Delhi-based NRDC India. “While Banda has always been known for hot summers, what is changing right now is the intensity, the duration and the number of people exposed to dangerous heat conditions.”

High nighttime temperatures are especially worrying because they prevent people from recovering physically from the day’s heat, he says.

The top government official in Banda says authorities have responded by opening cooling centers, distributing hundreds of thousands of oral rehydration kits and monitoring hospitals during heat warnings.

Amit Aasery, the district magistrate of Banda, says officials are studying groundwater levels, soil moisture and vegetation loss while working to improve water supplies and public awareness.

But he says there is only so much they can do.

“What is happening here is a global phenomenon,” he says. “It is because of climate change. We are the recipient of this.”

Seven Greek islands in the Aegean Sea have declared drought emergencies this year to preserve water as climate change makes summers hotter and rainfall more erratic.

Now, authorities are wondering if it will rain next year to sustain the thousands of tourists who strain the supply of water just when locals need it most.

The butterfly-shaped island of Astypalaia, which relies on bottled water for drinking, lies east of the mainland and did not benefit from rain in northern and western parts of Greece that gave the country its wettest winter since 2022.

For Astypalaia in the southeastern Aegean, it was the second driest season since 2020, according to data by local authorities, creating dilemmas for officials.

"If we collected all the water dropped throughout the year in a bucket or in a washbowl, it would be 2.5 centimeters deep," said mayor Nikos Komineas, standing near a man-made lake surrounded by dry hills with sparse low scrub, the island's sole water reservoir built in the mid-1990s.

Authorities cut ⁠off farmer Evdokia Palatianou from a man-made lake to save water in April. The vegetables she grows in her orchard withered as she was forced to rely on brackish water pumped from her well.

"Unless it rains, I won't plant anything," said Palatianou, 71, standing next to a dead tree once full of mandarins on the coastal village of Livadi, the island's main fertile region.

The lake supplying water for household use and irrigation in Livadi and to the main tourist town of Chora, the island's capital, now contains some 150,000 cubic meters, a sixth of its storage capacity.

With daily consumption at about 900 cubic meters ⁠in the summer, it would last around five and a half months.

Authorities declared a water emergency in May to fast-track a temporary desalination plant with a daily output of 600 cubic meters for Chora, and blocked irrigation for farmers in Livadi to safeguard the lake's reserves until autumn, Reuters quoted Komineas as saying.

"We did it with a heavy heart, but anyway, thankfully there's this alternative for them," he said, adding that if rain replenishes the Livadi reservoir, they will reconnect the farmers.

A map compiled by the Copernicus European Drought Observatory marked Astypalaia in orange in June, an early sign of emerging drought.

At the seaside village of Analipsi on the island's east, sheep and goat farmers carry in water to fill up tanks or use low-quality water from boreholes.

A desalination plant that supplies tap water there was unable to cover a population that swells to 7,000 from 1,400 in midsummer, so a second, temporary facility was set up in Chora pending ⁠construction of a permanent one ⁠planned for the end of the year.

Dozens of energy-intensive desalination plants are installed on Greek islands. Κomineas said the temporary plant was a fallback for drought, while admitting it was costly.

"A major worry for me was what will happen if there is no rain once again this year," he said.

Some hoteliers on Astypalaia have already taken action to save water. Carolina Alkalai, 42, who operates a hotel on a hillside in Chora, with views of the castle and the Aegean Sea, offers a 5-euro voucher to guests who skip the daily cleaning service.

"Clients have embraced it," she said. She envisioned a second hotel on the island that would incorporate a cistern able to retain rainwater instead of a pool or a jacuzzi.

Environment Minister Stavros Papastavrou has approved 15-million-euros ($17 million) for desalination, grid upgrades and water tanks on nine of Greece's more than 200 inhabited islands, including 1.5 million euros for Astypalaia. In June, he briefed other environment ministers in Luxembourg on water resilience.

"For Greece, water isn't theoretical- it's about security, economic growth and the protection of local communities," he said. The Athens-based National Centre for Scientific Research "Demokritos" says drought could get worse by 2049 as global temperatures rise, exacerbating water scarcity on the vulnerable islands.
