France's Heat This Week Was Worse Than a Dire Scenario Imagined For 2050

2 weeks ago
There's a deadly, record-breaking heat wave spreading east across Europe, reports the Washington Post — and it's even worse than a dire earlier forecast: The forecast was recorded in 2014 as part of a campaign coordinated by the World Meteorological Organization (WMO) that invited about 60 presenters worldwide to imagine a weather report from the year 2050. In one clip, Ãvelyne Dhéliat from French television network TF1 presented a hypothetical scenario of high temperatures 36 years into the future — during a heat wave in a warmer climate in 2050... One of the maps that Dhéliat shared was lit up in shades of orange, filled with temperature predictions of 40 degrees Celsius (104 degrees Fahrenheit), reaching as high as 43 degrees Celsius (109.4 degrees Fahrenheit). But it turns out, it didn't take 36 years for those imagined temperatures to be reached — and even exceeded. The heat on Wednesday alone, when the temperature soared as high as 112.3 degrees Fahrenheit (44.3 degrees Celsius), exceeded the 2050 projections in 19 out of 34 locations across mainland France — far sooner than some may have expected. Some places surpassed those hypothetical future temperatures by more than 20 degrees Fahrenheit. It's part of a dramatic shift in heat wave frequency across the country. Half of the heat waves observed since 1947 have occurred since 2010. "By 2100, heat waves could last up to two months continuously," the country's weather agency, Météo-France, said this week. It was hotter in France on Wednesday than in Las Vegas and Phoenix and just two degrees Fahrenheit shy of what was observed in Death Valley, California. An estimated less than one percent of the planet was hotter than France's hottest place... [T]he heat dome, which will linger into early next week, is only part of the story. This type of extreme heat is becoming more common as the planet warms, especially in Europe. Climate scientist Robert Rohde said in a post explaining the heat wave's causes that France and Western Europe should expect many more heat waves like this over the coming decades. "This isn't a fluke, but simply part of the new normal," he said. Thanks to Slashdot reader fjo3 for sharing the news.

Max Planck Slapped With Two Paper Retractions By Suspected Rogue Algorithm

2 weeks 1 day ago
Max Planck won 1918's Nobel Prize for physics. Yet two of his papers were retracted — a move now being criticized by Yves Gingras, a historian of physics at the University of Quebec and Mahdi Khelfaoui, a fellow historian of science at UQ Trois-Rivières. Science reports: The papers, both quietly retracted in 2011, originally appeared in the early 1940s in Naturwissenschaften, a German journal now owned by publishing giant Springer Nature. After some sleuthing, Khelfaoui determined one of the Planck pieces, a philosophical essay from 1942 titled "Sinn und Grenzen der exakten Wissenschaft" ("Meaning and Limits of Exact Science"), about how to achieve certainty in scientific knowledge, had also appeared in two other journals and been reprinted twice in books. Repackaging the same work multiple times is considered "self-plagiarism" and frowned upon today — the practice produces copyright conflicts and inflates scholars' publication records. The Naturwissenschaften site gives "copyright violation" as the reason for the retraction. Yet publishing identical material in multiple journals was widespread before the internet. "Science was more fragmented" then, Khelfaoui says. "You wanted different audiences ... to have access to your work." The practice was especially common for luminaries like Planck. Albert Einstein did the same (but escaped retractions). Springer Nature's "anachronistic" application of modern standards to a 1942 paper "distort[s] the historical record," Gingras and Khelfaoui argue in a preprint posted last month on arXiv. Any concerns about copyright violations are largely moot anyway: Because Planck died in 1947, his works are in the public domain in most countries. Gingras was especially incensed that Springer Nature deviated from the normal practice of merely slapping the word RETRACTED across the digital version of the paper while still allowing scholars to read the text. Instead, the publisher posted a blank white page with the cryptic phrase, "This article has been withdrawn due to article violation." Springer Nature is nevertheless still selling the empty PDF for $39.95. Suzanne Scarlata, a chemist and biochemist at the Worcester Polytechnic Institute and editor-in-chief of The Science of Nature, as Naturwissenschaften is now known, had not heard about the retractions before being contacted for this story... Scarlata suspects Springer Nature's internal policing software removed the paper and posted the retraction notice unilaterally, without human supervision: "I think it just happened with their algorithm," she says. "It's a mistake they should probably rectify." A second Planck paper was apparently removed because its response to a 1940 paper had used an identical title.

Scroll Burned in 79 AD Volcanic Eruption Finally Deciphered Using AI

2 weeks 1 day ago
When Mt. Vesuvius erupted in 79 A.D., it buried hundreds of papyrus scrolls. They were rediscovered in the mid-1700s, remembers Smithsonian magazine, "the only surviving collection of its kind from the Greco-Roman world..." "But when scholars tried to unroll them, the carbonized manuscripts crumbled to dust." Every generation that followed faced the same dilemma: They could wait for technology to advance, abandoning hope of reading the ancient texts in their own lifetime. Or they could try to open the scrolls themselves — and risk destroying them. In recent years, researchers have settled on a third option. Using advanced imaging and artificial intelligence, they're deciphering the scrolls without needing to unroll them at all. The Vesuvius Challenge has accelerated the process by turning it into a public competition, complete with cash prizes. In 2023, a student won $40,000 for deciphering a single word — "purple" — from an unopened scroll. Later, contestants would identify 2,000 Greek characters from one scroll ($700,000) and the title of another ($60,000). Now, for the very first time, researchers have recovered all surviving text from a single scroll. The nearly five-foot-long segment includes roughly 20 columns of ancient Greek philosophy, accessible for the first time in nearly 2,000 years. "The tech actually does look like magic, but it's not," Brent Seales, a computer scientist at the University of Kentucky, said at a press conference. (The article points out that Seales partnered with two Silicon Valley investors in 2023 to launch the Vesuvius Challenge, and is now hailing "the restoration of lost voices from the ancient world." Seales has been working on virtually unwrapping the scrolls since the early 2000s. The process involved imaging the bundles of papyrus using technology similar to CT scanners, isolating thin layers and then stitching them together.... "We've developed a systematic and a repeatable approach," Seales told the audience. "Now it's only a matter of time until we read all of the scrolls."
