    Baltazar Ushca, Who Kept Andean Ice Harvesting Alive, Dies at 80

    by

    He trekked up Ecuador’s tallest mountain twice a week for six decades to hack ice off a glacier with a pickax. He is believed to have been the last of his breed.For 60 years, Baltazar Ushca worked a rare but rigorous trade: ice merchant. Once or twice a week, he climbed snow-capped Mount Chimborazo, Ecuador’s highest peak, to hack ice from a glacier with a pickax, wrap the 60-pound blocks in hay and transport them on the backs of his donkeys. He would then sell them to villagers who did not have electricity and needed refrigeration to conserve their food.It started as a family business. Mr. Ushca’s father, Juan, was an ice merchant, as were his brothers, Juan and Gregorio, and they made their very modest livings off the Chimborazo ice.But Mr. Ushca, who was 4-foot-11, chipped at the ice decades after modern refrigeration came to his village, by which time his job was nearly obsolete. He gradually became known as the last of his breed, selling his blocks of ice for a few dollars each largely to vendors in a market in Riobamba, Ecuador, for use in fruit drinks and making ice cream.“The natural ice from Chimborazo is the best ice,” Mr. Ushca said in a short documentary, “El Último Hielero,” or “The Last Ice Merchant” (2012), directed by Sandy Patch. “The tastiest and the sweetest. Full of vitamins for your bones.”Once he reached the market, he delivered the blocks of ice by carrying them on his back.“My kids would say, ‘Why suffering so much?’” Gregorio Ushca said the documentary. “‘Being so cold, walking far, if you almost make no money?’”Since he was 15, Baltazar Ushca has harvested the glacial ice of Ecuador’s Mount Chimborazo. His brothers have long since retired. “El Último Hielero” is a story of cultural change and adaption.We are having trouble retrieving the article content.Please enable JavaScript in your browser settings.Thank you for your patience while we verify access.

      Ruth Glacier in Alaska Hides America’s Deepest Gorge

      by

      As his bush plane circled the craggy peaks of the Alaska Range, the explorer Bradford Washburn peered down and had a burning thought.Coursing down the southern slopes of Denali and Mount Silverthrone were the accumulated snows of thousands of winters, compacted under their own weight into colossal rivers of ice that filled the valleys for miles in every direction. At one particular spot in the white wilderness, Washburn noticed from above, all this glacial mass was somehow squeezing through a granite-walled corridor just a mile wide.Washburn became convinced, he wrote, that beneath the ice lay a secret: The corridor was deep. Deeper, perhaps, than any other gorge on the continent, and maybe even the planet.That was 1937. Nearly 90 years later, a team of scientists set off into the windswept mountains to measure the glacier with snowmobiles and ice-penetrating radar. It wasn’t easy: The Great North does not surrender its mysteries readily. The researchers almost didn’t think they’d found anything of interest.The Ruth Glacier originates beneath the summit of Denali and flows through deep granite valleys.Now, thanks to some clever analysis, and a bit of luck, they have put forth the most conclusive evidence yet that Washburn was right — that the area could be the deepest gorge in North America.We are having trouble retrieving the article content.Please enable JavaScript in your browser settings.Thank you for your patience while we verify access.

      How Close Are the Planet’s Climate Tipping Points?

      by

      Right now, every moment of every day, we humans are reconfiguring Earth’s climate bit by bit. Hotter summers and wetter storms. Higher seas and fiercer wildfires. The steady, upward turn of the dial on a host of threats to our homes, our societies and the environment around us. We might also be changing the climate […] More

      Alaska’s Juneau Ice Field Is Melting at an ‘Incredibly Worrying’ Pace, Scientists Say

      by

      The speed of decline in the Juneau Ice Field, an expanse of 1,050 interconnected glaciers, has doubled in recent decades, scientists discovered.One of North America’s largest areas of interconnected glaciers is melting twice as quickly as it did before 2010, a team of scientists said Tuesday, in what they called an “incredibly worrying” sign that land ice in many places could disappear even sooner than previously thought.The Juneau Ice Field, which sprawls across the Coast Mountains of Alaska and British Columbia, lost 1.4 cubic miles of ice a year between 2010 and 2020, the researchers estimated. That’s a sharp acceleration from the decades before, and even sharper when compared with the mid-20th century or earlier, the scientists said. All told, the ice field has shed a quarter of its volume since the late 18th century, which was part of a period of glacial expansion known as the Little Ice Age.As societies add more and more planet-warming carbon dioxide to the atmosphere, glaciers in many areas could cross tipping points beyond which their melting speeds up rapidly, said Bethan Davies, a glaciologist at Newcastle University in England who led the new research.“If we reduce carbon, then we have more hope of retaining these wonderful ice masses,” Dr. Davies said. “The more carbon we put in, the more we risk irreversible, complete removal of them.”The scientists’ findings were published on Tuesday in the journal Nature Communications.The fate of Alaska’s ice matters tremendously for the world. In no other region of the planet are melting glaciers predicted to contribute more to global sea-level rise this century.We are having trouble retrieving the article content.Please enable JavaScript in your browser settings.Thank you for your patience while we verify access.

      A ‘Corpsicle’ Came Back to Life on ‘True Detective.’ Is That Possible?

      by

      An incident involving a group of frozen bodies on the fourth season of the HBO series has raised some scientific questions.The men lay frozen naked in a ghoulish pile, with mouths agape and eyes glazed over, their hair encrusted with ice and snow. They were all dead — or so the investigators on the HBO series “True Detective: Night Country” thought.Frozen bodies are a familiar problem in this fictional Alaska town near the Arctic Circle, but this giant “corpsicle” is unusual. And so is what happens at the end of the episode, which aired last Sunday: one of the men wakes up when his arm is accidentally snapped off by an officer.The resurrection has sparked grisly speculation among some fans: How can a person be living, a viewer on Reddit asked, if that person’s limbs are so frozen? “They could have been flash frozen in a moment of terror” at the moment of their deaths, another speculated. Many were skeptical that the human body could survive such an ordeal and wondered if the show was straying into the supernatural.Doctors say that it is impossible for a completely frozen person to make a recovery. But it is possible for someone who appears frozen — limbs stiff, skin cold and hard, and without a pulse or breath — to be resuscitated, depending on how long the person has been out in the cold.“If all the tissue in your body is ice, or has ice in it, then you’re not coming back,” said Ken Zafren, a physician and a professor of emergency medicine at Stanford University, who also works in Alaska. But, he added, “I’ve seen plenty of cases in which the person really looked dead, and could come back.”During hypothermia, an adult’s body temperature can cool well below the normal average of 98.6 degrees, Dr. Zafren said. A person’s pulse and breathing slow significantly, reducing the body’s need for oxygen. Eventually, the person may go into cardiac arrest, stopping the pulse and breathing altogether. But because the brain is cold, the lack of oxygen takes longer to cause damage, he said.We are having trouble retrieving the article content.Please enable JavaScript in your browser settings.Thank you for your patience while we verify access.
