Apple is blaming a software bug and other issues tied to popular apps such as Instagram and Uber for causing its recently released iPhone 15 models to heat up and spark complaints about becoming too hot to handle.

The Cupertino, California, company said Saturday that it is working on an update to the iOS17 system that powers the iPhone 15 lineup to prevent the devices from becoming uncomfortably hot and is working with apps that are running in ways “causing them to overload the system.”

Instagram, owned by Meta Platforms, modified its social media app earlier this week to prevent it from heating up the device on the latest iPhone operating system.

Uber and other apps such as the video game Asphalt 9 are in the process of rolling out their updates, Apple said. It didn’t specify a timeline for when its own software fix would be issued but said no safety issues should prevent iPhone 15 owners from using their devices while awaiting the update.

“We have identified a few conditions which can cause iPhone to run warmer than expected,” Apple in a short statement provided to The Associated Press after media reports detailed overheating complaints that are peppering online message boards.

The Wall Street Journal amplified the worries in a story citing the overheating problem in its own testing of the new iPhones, which went on sale a week ago.

It’s not unusual for new iPhones to get uncomfortably warm during the first few days of use or when they are being restored with backup information stored in the cloud — issues that Apple already flagged for users. The devices also can get hot when using apps such as video games and augmented reality technology that require a lot of processing power, but the heating issues with the iPhone 15 models have gone beyond those typical situations.

In its acknowledgement, Apple stressed that the trouble isn’t related to the sleek titanium casing that houses the high-end iPhone 15 Pro and iPhone 15 Pro Max instead of the stainless steel used on older smartphones.

Apple also dismissed speculation that the overheating problem in the new models might be tied to a shift from its proprietary Lightning charging cable to the more widely used USB-C port that allowed it to comply with a mandate issued by European regulators.

Although Apple expressed confidence that the overheating issue can be quickly fixed with the upcoming software updates, the problem still could dampen sales of its marquee product at a time when the company has faced three consecutive quarters of year-over-year declines in overall sales.

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.
