In pockets of Europe’s Alpine mountains, glaciers are abundant enough that ski resorts operate above the snow and ice.

Ski lifts, resorts, cabins and huts dot the landscape — and have done so for decades. But glaciers are also one of the most obvious and early victims of human-caused climate change, and as they shrink year by year, the future of the mountain ecosystems and the people who enjoy them will look starkly different.

Glaciers — centuries of compacted snow and ice — are disappearing at an alarming rate. Swiss glaciers have lost 10% of their volume since 2021, and some glaciers are predicted to disappear entirely in the next few years.

At the Freigerferner glacier in Austria, melting means the glacier has split into two and hollowed out as warm air streamed through the glacier base, exacerbating the thaw.

Gaisskarferner, another glacier that forms part of a ski resort, is only connected to the rest of the snow and ice by sections of glacier that were saved over the summer with protective sheets to shield them from the sun.

But the losses go beyond a shorter ski season and glacier mass.

Andrea Fischer, a glaciologist with the Austrian Academy of Sciences, said the rate of glacier loss can tell the world more about the state of the climate globally and how urgent curbing human-caused warming is.

“The loss of glaciers is not the most dangerous thing about climate change,” said Fischer. “The most dangerous thing about climate change is the effect on ecosystems, on natural hazards, and those processes are much harder to see. The glaciers just teach us how to see climate change.”

From a vantage point above the mountains in a light aircraft, the changing landscape is obvious. The glaciers are noticeably smaller and fewer, and bare rock lies in their place.

Much of the thawing is already locked in, so that even immediate and drastic cuts to planet-warming emissions can’t save the glaciers from disappearing or shrinking in the short term.

While the extent of glacier melt can create awareness and concern for the climate, “being only concerned does not change anything,” Fischer said.

She urged instead that concern should be channeled into “a positive attitude toward designing a new future,” where warming can successfully be curbed to stop the most detrimental effects of climate change.

The U.S. West Coast produces over 90% of America’s wine, but the region is also prone to wildfires — a combustible combination that spelled disaster for the industry in 2020 and one that scientists are scrambling to neutralize.

Sample a good wine and you might get notes of oak or red fruit. But sip on wine made from grapes that were penetrated by smoke, and it could taste like someone dumped the contents of an ashtray into your glass.

Wine experts from three West Coast universities are working together to meet the threat, including developing spray coatings to protect grapes, pinpointing the elusive compounds that create that nasty ashy taste, and deploying smoke sensors to vineyards to better understand smoke behavior.

The U.S. government is funding their research with millions of dollars.

Wineries are also taking steps to protect their product and brand.

The risk to America’s premier wine-making regions — where wildfires caused billions of dollars in losses in 2020 — is growing, with climate change deepening drought and overgrown forests becoming tinderboxes.

According to the U.S. Department of Agriculture, grapes are the highest-value crop in the United States, with 1 million acres (405,000 hectares) of grape-bearing land, 96% of it on the West Coast.

Winemakers around the world are already adapting to climate change, including by moving their vineyards to cooler zones and planting varieties that do better in drought and heat. Wildfires pose an additional and more immediate risk being tackled by scientists from Oregon State University, Washington State University and the University of California, Davis.

“What’s at stake is the ability to continue to make wine in areas where smoke exposures might be more common,” said Tom Collins, a wine scientist at Washington State University.

Researcher Cole Cerrato recently stood in Oregon State University’s vineyard, nestled below forested hills near the village of Alpine, as he turned on a fan to push smoke from a Weber grill through a dryer vent hose. The smoke emerged onto a row of grapes enclosed in a makeshift greenhouse made of taped-together plastic sheets.

Previously, grapes exposed to smoke in that setup were made into wine by Elizabeth Tomasino, an associate professor leading Oregon State’s efforts, and her researchers.

They found sulfur-containing compounds, thiophenols, in the smoke-impacted wine and determined they contributed to the ashy flavor, along with “volatile phenols,” which Australian researchers identified as factors more than a decade ago. Bush fires have long impacted Australia’s wine industry. Up in Washington state, Collins confirmed that the sulfur compounds were found in the wine that had been exposed to smoke in the Oregon vineyard but weren’t in samples that had no smoke exposure.

The scientists want to find out how thiophenols, which aren’t detectable in wildfire smoke, appear in smoke-impacted wine, and learn how to eliminate them.

“There’s still a lot of very interesting chemistry and very interesting research, to start looking more into these new compounds,” Cerrato said. “We just don’t have the answers yet.”

Wine made with tainted grapes can be so awful that it can’t be marketed. If it does go on shelves, a winemaker’s reputation could be ruined — a risk that few are willing to take.

When record wildfires in 2020 blanketed the West Coast in brown smoke, some California wineries refused to accept grapes unless they had been tested. But most growers couldn’t find places to analyze their grapes because the laboratories were overwhelmed.

The damage to the industry in California alone was $3.7 billion, according to an analysis that Jon Moramarco of the consulting firm bw166 conducted for industry groups. The losses stemmed mostly from wineries having to forego future wine sales.

“But really what drove it was, you know, a lot of the impact was in Napa [Valley], an area of some of the highest priced grapes, highest priced wines in the U.S.,” Moramarco said, adding that if a ton of cabernet sauvignon grapes is ruined, “you lose probably 720 bottles of wine. If it is worth $100 a bottle, it adds up very quickly.”

Between 165,000 to 325,000 tons of California wine grapes were left to wither on the vine in 2020 due to actual or perceived wildfire smoke exposure, said Natalie Collins, president of the California Association of Winegrape Growers.

She said she hasn’t heard of any growers quitting the business due to wildfire impacts, but, “Many of our members are having an extremely difficult time securing insurance due to the fire risk in their region, and if they are able to secure insurance, the rate is astronomically high.”

Some winemakers are trying techniques to reduce smoke impact, such as passing the wine through a membrane or treating it with carbon, but that can also rob a wine of its appealing nuances. Blending impacted grapes with other grapes is another option. Limiting skin contact by making rosé wine instead of red can lower the concentration of smoke flavor compounds.

Collins, over at Washington State University, has been experimenting with spraying fine-powdered kaolin or bentonite, which are clays, mixed with water onto wine grapes so it absorbs materials that are in smoke. The substance would then be washed off before harvest. Oregon State University is developing a spray-on coating.

Meanwhile, dozens of smoke sensors have been installed in vineyards in the three states, financed in part by a $7.65 million USDA grant.

“The instruments will be used to measure for smoke marker compounds,” said Anita Oberholster, leader of UC Davis’ efforts. She said such measurements are essential to develop mitigation strategies and determine smoke exposure risk.

Greg Jones, who runs his family’s Abacela winery in southern Oregon’s Umpqua Valley and is a director of the Oregon Wine Board, applauds the scientists’ efforts.

“This research has really gone a long way to help us try to find: Are there ways in which we can take fruit from the vineyard and quickly find out if it has the potential compounds that would lead to smoke-impacted wine?” Jones said.

Collins predicts success.

“I think it’s increasingly clear that we’re not likely to find a magic bullet,” he said. “But we will find a set of strategies.”

How do you cook a meal when a staple ingredient is unaffordable? 

This question is playing out in households around the world as they face shortages of essential foods like rice, cooking oil and onions. That is because countries have imposed restrictions on the food they export to protect their own supplies from the combined effect of the war in Ukraine, El Nino’s threat to food production and increasing damage from climate change. 

For Caroline Kyalo, a 28-year-old who works in a salon in Kenya’s capital of Nairobi, it was a question of trying to figure out how to cook for her two children without onions. Restrictions on the export of the vegetable by neighboring Tanzania has led prices to triple. 

Kyalo initially tried to use spring onions instead, but those also got too expensive. As did the prices of other necessities, like cooking oil and corn flour. 

“I just decided to be cooking once a day,” she said. 

Despite the East African country’s fertile lands and large workforce, the high cost of growing and transporting produce and the worst drought in decades led to a drop in local production. Plus, people preferred red onions from Tanzania because they were cheaper and lasted longer. By 2014, Kenya was getting half of its onions from its neighbor, according to a U.N. Food Agriculture Organization report. 

At Nairobi’s major food market, Wakulima, the prices for onions from Tanzania were the highest in seven years, seller Timothy Kinyua said. 

Some traders have adjusted by getting produce from Ethiopia, and others have switched to selling other vegetables, but Kinyua is sticking to onions. 

“It’s something we can’t cook without,” he said. 

Tanzania’s onion limits this year are part of the “contagion” of food restrictions from countries spooked by supply shortages and increased demand for their produce, said Joseph Glauber, senior research fellow at the International Food Policy Research Institute. 

Globally, 41 food export restrictions from 19 countries are in effect, ranging from outright bans to taxes, according to the institute. 

India banned shipments of some rice earlier this year, resulting in a shortfall of roughly a fifth of global exports. Neighboring Myanmar, the world’s fifth-biggest rice supplier, responded by stopping some exports of the grain. 

India also restricted shipments of onions after erratic rainfall — fueled by climate change — damaged crops. This sent prices in neighboring Bangladesh soaring, and authorities are scrambling to find new sources for the vegetable. 

Elsewhere, a drought in Spain took its toll on olive oil production. As European buyers turned to Turkey, olive oil prices soared in the Mediterranean country, prompting authorities there to restrict exports. Morocco, also coping with a drought ahead of its recent deadly earthquake, stopped exporting onions, potatoes and tomatoes in February. 

This isn’t the first time food prices have been in a tumult. Prices for staples like rice and wheat more than doubled in 2007-2008, but the world had ample food stocks it could draw on and was able to replenish those in subsequent years. 

But that cushion has shrunk in the past two years, and climate change means food supplies could very quickly run short of demand and spike prices, said Glauber, former chief economist at the U.S. Department of Agriculture. 

“I think increased volatility is certainly the new normal,” he said. 

Food prices worldwide, experts say, will be determined by the interplay of three factors: how El Nino plays out and how long it lasts, whether bad weather damages crops and prompts more export restrictions, and the future of Russia’s war in Ukraine. 

The warring nations are both major global suppliers of wheat, barley, sunflower oil and other food, especially to developing nations where food prices have risen and people are going hungry. 

An El Nino is a natural phenomenon that shifts global weather patterns and can result in extreme weather, ranging from drought to flooding. While scientists believe climate change is making this El Nino stronger, its exact impact on food production is impossible to glean until after it’s occurred. 

The early signs are worrying. 

India experienced its driest August in a century, and Thailand is facing a drought that has sparked fears about the world’s sugar supplies. The two are the largest exporters of sugar after Brazil. 

Less rainfall in India also dashed food exporters’ hopes that the new rice harvest in October would end the trade restrictions and stabilize prices. 

“It doesn’t look like [rice] prices will be coming down anytime soon,” said Aman Julka, director of Wesderby India Private Limited. 

Most at risk are nations that rely heavily on food imports. The Philippines, for instance, imports 14% of its food, according to the World Bank, and storm damage to crops could mean further shortfalls. Rice prices surged 8.7% in August from a year earlier, more than doubling from 4.2% in July. 

Food store owners in the capital of Manila are losing money, with prices increasing rapidly since September 1 and customers who used to snap up supplies in bulk buying smaller quantities. 

“We cannot save money anymore. It is like we just work so that we can have food daily,” said Charina Em, 32, who owns a store in the Trabajo market. 

Cynthia Esguerra, 66, has had to choose between food or medicine for her high cholesterol, gallstones and urinary issues. Even then, she can only buy half a kilo of rice at a time — insufficient for her and her husband. 

“I just don’t worry about my sickness. I leave it up to God. I don’t buy medicines anymore, I just put it there to buy food, our loans,” she said. 

The climate risks aren’t limited to rice but apply to anything that needs stable rainfall to thrive, including livestock, said Elyssa Kaur Ludher, a food security researcher at the ISEAS-Yusof Ishak Institute in Singapore. Vegetables, fruit trees and chickens will all face heat stress, raising the risk that food will spoil, she said. 

This constricts food supplies further, and if grain exports from Ukraine aren’t resolved, there will be additional shortages in feed for livestock and fertilizer, Ludher said. 

Russia’s July withdrawal from a wartime agreement that ensured ships could safely transport Ukrainian grain through the Black Sea was a blow to global food security, largely leaving only expensive and divisive routes through Europe for the war-torn country’s exports. 

The conflict also has hurt Ukraine’s agricultural production, with analysts saying farmers aren’t planting nearly as much corn and wheat. 

“This will affect those who already feel food affordability stresses,” Ludher said.

Many millions of Chinese tourists are expected to travel within their country, splurging on hotels, tours, attractions and meals in a boost to the economy during the 8-day autumn holiday period that began Friday.

This year’s holiday began with the Mid-Autumn Festival on Friday and also includes the Oct. 1 National Day. The public holidays end Oct. 6.

Typically hundreds of millions of Chinese travel at home and overseas during such holidays. The eight-day-long holiday is the longest week of public holidays since COVID-19 pandemic restrictions were lifted in December. Outbound tourism has lagged domestic travel, with flight capacities lagging behind pre-pandemic levels.

Big cities like the capital, Beijing, Shanghai, and southern cities like Shenzhen and Guangzhou are favored destinations. Smaller cities, such as Chengdu and Chongqing in southwest China also are popular.

All that travel is a boon for the world’s No. 2 economy: During the week-long May holiday this year, 274 million tourists spent 148 billion yuan ($20.3 billion).

“Over the last few years with the pandemic, there’s been really strong pent-up demand,” said Boon Sian Chai, managing director at the online travel booking platform Trip.com Group. Both domestic and outbound travel have “recovered significantly,” but travel within China accounted for nearly three-quarters of total bookings, Chai said.

China Railway said it was expecting about 190 million passenger trips during the Sept. 27-Oct. 8 travel rush, more than double the number of trips last year and an increase from 2019, before the pandemic started.

In Guangzhou and Shenzhen, extra overnight high-speed trains will operate for 11 days to cope with a travel surge during the long holiday, according to the China Railway Guangzhou Group Co., Ltd.

Another 21 million passengers are expected to travel by air during the holiday, with an average of about 17,000 flights per day, according to the Civil Aviation Administration of China. More than 80% of those flights are domestic routes.

Jia Jianqiang, CEO of Liurenyou International Travel Agency, said Chinese are splurging on more luxurious travel.

“Many people are now also inclined towards more customized, high-end tours compared to the large group tours that were popular (before the pandemic),” Jia said.

For many Chinese, long public holidays such as Golden Week are the best time to travel, since paid vacation can be as few as five days a year.

“Most Chinese don’t have long holidays, so this time of the year is when everyone can take the longest break and the only time to travel for fun,” said Fu Zhengshuai, an IT engineer and photography enthusiast who often travels alone to remote areas in China such as far western Qinghai and Xinjiang.

The downside of traveling during such big holidays is that everyone else is out there, too, and prices of tickets to attractions, food, and accommodations are high, Fu said.

For student Ma Yongle, traveling during big holidays means long waiting times, huge crowds, and heavy traffic. Train tickets often are sold out.

“I saw more people than scenery. I spent longer time waiting than eating. Train tickets were sold out quickly and traffic was heavy,” Ma said. “More time was wasted and little was left for enjoying the scenery, which spoiled my mood.”

She has since adopted what is referred in China as a “special forces travel trend” where tourists don’t stay overnight at a destination, but only take day trips to save money.

A growing but still relatively small number of Chinese are venturing abroad. According to Trip.com data, outbound travel orders this year are nearly 20 times those during last year’s autumn holidays, when many pandemic restrictions were still in place. Thailand, Singapore, South Korea and Malaysia are popular destinations, as are more distant places such as Australia and the United Kingdom.

Overseas travel is bound to bounce back, Chai said.

“If you look at flight capacity, it has only recovered to about half of pre-pandemic levels,” he said. “As flight capacity starts to pick up toward the end of this year and next year, outbound travel will continue to increase.”

The streets of cities across Latin America were bathed in green Thursday as tens of thousands of women marched to commemorate International Safe Abortion Day.

Latin American feminists have spent decades fighting to roll back strict prohibitions, although there are still few countries with a total ban, like El Salvador and Dominican Republic.

In Mexico, marchers celebrated the recent decision by Mexico’s Supreme Court to decriminalize abortions at the federal level. In Argentina, marchers had a more somber tone, worrying that the strength of a populist far-right presidential candidate going into elections in October could signal peril after years of work by feminists.

Abortion was the heart of the protests, but crowds of women also raised alarm about the region’s high rates of gender-based violence as well as abuses aimed at LGBTQ+ communities.

Green smoke floated over a roaring crowd of thousands of women in Mexico City who waved green handkerchiefs, which have become the symbol of Latin America’s “green wave” abortion movement. Signs reading “It’s my decision” and “Free and safe abortions for everyone” speckled the crowd.

The march came just weeks after Mexico’s Supreme Court knocked down all federal criminal penalties for abortion, ruling that national laws prohibiting the procedure are unconstitutional and violate women’s rights. The move will also require federal health institutions to offer abortion to anyone who requests it.

“It’s absolutely an achievement,” said Fernanda Castro, an organizer at GIRE, the women’s rights organization that brought forward the lawsuit before Mexico’s high court. “And now we have another even more important fight — decriminalizing abortion in the minds of the people.”

While 20 Mexican states still have abortion bans on the books, the decision by the Supreme Court greatly expanded access to the procedure in a country where reproductive laws were long defined by its religious and conservative roots.

Latin American feminists have spent decades fighting to roll back strict prohibitions.

Mexico City was the first Mexican jurisdiction to decriminalize abortion 15 years ago. The trend picked up speed in Argentina, which in 2020 legalized the procedure. In 2022, Colombia, a highly conservative country, did the same.

Brazil may be next. Currently, abortion is a crime with exceptions for cases of rape and birth defects in a fetus, but a case before the nation’s Supreme Court could potentially decriminalize the procedure up to 12 weeks of gestation.

“The green wave is going to keep growing and (Brazilian women) are not alone,” Castro said.

While marches in Mexico and other parts of the region were celebratory, in Argentina’s capital of Buenos Aires, the demonstration was marked with unease.

As elections loom in October, many in the crowd marching toward the Congress building fear their legal gains may soon get rolled back with the rise of right-wing candidate Javier Milei.

Now the leading candidate in polls, Milei, has spoken out against abortion, compulsory sex education in schools and free medical coverage for sex change treatments, among other issues. If he wins, he has promised to hold a referendum to repeal the decriminalization of abortion nationwide approved by Congress in 2022.

“More than winning more rights, this is about protecting them. The most important thing is to protect what’s already there,” said Sara Rivas, an art student. “Milei is a denialist. We’ve seen him deny everything from femicides to the years-long struggle that has brought us to this green wave.”

Still, Rivas, who carried a sign with a drawing of Milei hanging from a green bandana, said women will turn to the same approach they have used for decades to press for their goals.

“Our answer is that we are here. We are not going to leave the streets, because these gains, we conquered them in the streets,” she said.

Federal health advisers voted overwhelmingly against an experimental treatment for Lou Gehrig’s disease at a Wednesday meeting prompted by years of patient efforts seeking access to the unproven therapy.

The panel of Food and Drug Administration experts voted 17-1 that drugmaker Brainstorm’s stem cell-based treatment has not been shown effective for patients with the fatal, muscle-wasting disease known as ALS, or amyotrophic lateral sclerosis. One panel member abstained from voting.

While the FDA is not bound by the vote, it largely aligns with the agency’s own strikingly negative review released earlier this week, in which staff scientists described Brainstorm’s application as “scientifically incomplete” and “grossly deficient.”

“Creating false hope can be considered a moral injury and the use of statistical magic or manipulation to provide false hope is problematic,” said Lisa Lee, a bioethics and research integrity expert from Virginia Tech who voted against the treatment. The lone positive vote came from a panel member representing patients.

Wednesday’s public meeting was essentially a longshot attempt by Brainstorm and the ALS community to sway FDA’s thinking on the treatment, dubbed NurOwn.

Brainstorm’s single 200-patient study failed to show that NurOwn extended life, slowed disease or improved patient mobility. But the FDA agreed to convene the panel of outside advisers after ALS patients and advocates submitted a 30,000-signature petition seeking a public meeting.

In the last year, the FDA has approved two new drugs for ALS, after a nearly 20-year drought of new options. The approvals followed intense lobbying by advocacy groups.

FDA leaders have recently emphasized a new level of “regulatory flexibility” when reviewing experimental treatments for fatal, hard-to-treat conditions, including ALS, Alzheimer’s and muscular dystrophy.

But the agency appears unwilling to overlook the failed study results and missing information in Brainstorm’s submission, including key details on manufacturing and quality control needed to establish the product’s safety.

“It really is a disease that needs a safe and effective treatment and there are a lot of other prospects out there that we need to encourage. Approving one like this would get in the way of that,” said Dr. Kenneth Fischbeck of the National Institutes of Health.

ALS destroys nerve cells in the brain and spinal cord needed to walk, talk, swallow and — eventually — breathe. Most people die within three to five years of their first symptoms.

More than a dozen people spoke during a public comment session Wednesday, including ALS patients, their family members and physicians who implored FDA to grant approval. Several speakers presented before-and-after videos showing patients who participated in Brainstorm’s study walking, climbing stairs and performing other tasks that they attributed to NurOwn.

“When Matt is on NurOwn it helps him, when he’s off of it he gets worse,” said Mitze Klingenberg, speaking on behalf of her son, Matt Klingenberg, who was diagnosed with ALS in 2018.

The FDA is expected to issue a decision on the therapy by December 8.

Israel-based Brainstorm Cell Therapeutics’ stock price has lost more than 90% of its value over the last year, falling to 39 cents per share before being halted ahead of Wednesday’s FDA meeting.

Environmental experts are ringing alarm bells, saying decades-long climate and environmental changes in Sudan have exacerbated social and political instability, fueling the monthslong conflict in the country centered around access to land, water and other vital resources.

The current conflict in Sudan, rooted in global geopolitics and the historical legacy of the previous leadership of now-deposed authoritarian leader Omar al-Bashir, is increasingly being attributed to climate change.

In a May report, Practical Action, a Britain-based international development organization, highlighted the impact of climate change in Sudan, which includes the encroachment of the desert southward and a stark reduction in rainfall.

Akinyi Walender, Practical Action Africa director, underscored the consequences of climate change in Sudan, including heightened drought, extreme rainfall variability, depletion of water sources and desertification spanning millions of hectares of land.

Speaking to VOA via WhatsApp, Walender said the conversion of migratory routes and pastureland into farmland has significantly disrupted “the natural balance” and accelerated desertification.

The United Nations says desertification is the persistent degradation of dryland ecosystems by climate change and mainly human activities — unsustainable farming, mining, overgrazing and clear-cutting of land.

The U.N. Convention to Combat Desertification says approximately 65% of Sudan’s land is affected by desertification.

Walender said climate change and conflict in Sudan are caught in a destructive cycle, potentially worsening the situation in the East African nation.

“The effects of war, such as the destruction of infrastructure, displacement of communities, and the use of airstrikes and heavy artillery, intensify the environmental damage in Sudan,” she said.

The International Organization for Migration, the U.N.’s migration agency, says nearly 7.1 million people are internally displaced within Sudan, 3.8 million being newly displaced due to the country’s monthslong conflict between the paramilitary Rapid Support Forces and the Sudanese Armed Force.

Awadalla Hamid, an environmental conservation manager at Practical Action in Sudan’s North Darfur State, said human activities have taken a toll on natural resources and ecosystems, intensifying environmental degradation.

Hamid said the displacement of communities in Sudan has led to further environmental damage.

“As people are forced to flee their homes, they often settle in temporary camps or new areas, leading to uncontrolled land-use changes, overexploitation of resources and increased pressure on fragile environments,” Hamid said. “The influx of displaced populations can also result in deforestation, soil erosion and pollution.”

The U.N. Environment Program says environmental destruction during conflicts has a direct impact on public health due to air and water pollution. The use of airstrikes and heavy artillery, while causing immediate destruction, also results in long-term environmental consequences, the U.N says.

Walender said addressing the environmental consequences of conflict requires a holistic approach —peacebuilding, conflict resolution and sustainable environmental practices.

Swar Adam, who fled violence in South Darfur and currently resides in Kosti, White Nile State, Sudan, told VOA his displacement has left him unable to tend to his livestock, which is his livelihood.

“It is very difficult at the moment to go and identify your cattle in such a situation,” Adam said. “I am not sure if they are now being fed on good grazing land or not. This is the situation I am in now.”
