Droughts in the coming decades could be longer than projected by current climate models, a new study published Wednesday in Nature warns.

The international team of scientists examined potential biases that could skew climate models used to make drought projections under Intergovernmental Panel on Climate Change midrange and high emissions scenarios. The researchers corrected for the bias by calibrating those models with observations of the longest annual dry spells between 1998 and 2018.

By the end of this century, they found that the average longest periods of drought could be 10 days longer than previously projected. Trouble spots included North America, Southern Africa, and Madagascar, where the newly calibrated models showed that the increase in the longest annual dry spell could be about twice what the older models predicted.

Google has won an appeal against a €1.5 billion competition fine from the European Commission in a victory for the Big Tech group as it comes under growing scrutiny from Brussels regulators.

The EU’s General Court said on Wednesday that while it accepted “most of the commission’s assessments” that the company had used its dominant position to block rival online advertisers, it annulled the hefty fine levied against Google in the case.

When launching the action against Google in 2019, Margrethe Vestager, the bloc’s competition chief, said that the search giant had imposed anti-competitive restrictions on third-party websites for a decade between 2006 and 2016. She justified the €1.5 billion fine by arguing that it reflected the “serious and sustained nature” of the infringement.

Amazon has told staff they must return to the office five days a week from the start of next year, one of the strictest corporate crackdowns on remote working that has become commonplace since the pandemic.

“We’ve decided that we’re going to return to being in the office the way we were before the onset of COVID,” chief executive Andy Jassy wrote in a memo to employees globally on Monday. “We’ve observed that it’s easier for our teammates to learn, model, practice, and strengthen our culture; collaborating, brainstorming, and inventing are simpler and more effective.

“Before the pandemic, it was not a given that folks could work remotely two days a week, and that will also be true moving forward,” Jassy said. He added exceptions would be made for employees with a sick child, family emergencies, or coding projects that needed a more isolated environment.

Earthquake scientists detected an unusual signal on monitoring stations used to detect seismic activity during September 2023. We saw it on sensors everywhere, from the Arctic to Antarctica.

We were baffled—the signal was unlike any previously recorded. Instead of the frequency-rich rumble typical of earthquakes, this was a monotonous hum, containing only a single vibration frequency. Even more puzzling was that the signal kept going for nine days.

Initially classified as a “USO”—an unidentified seismic object—the source of the signal was eventually traced back to a massive landslide in Greenland’s remote Dickson Fjord. A staggering volume of rock and ice, enough to fill 10,000 Olympic-sized swimming pools, plunged into the fjord, triggering a 200-meter-high mega-tsunami and a phenomenon known as a seiche: a wave in the icy fjord that continued to slosh back and forth, some 10,000 times over nine days.

Elon Musk has lambasted Australia’s government as “fascists” over proposed laws that could levy substantial fines on social media companies if they fail to comply with rules to combat the spread of disinformation and online scams.

The billionaire owner of social media site X posted the word “fascists” on Friday in response to the bill, which would strengthen the Australian media regulator’s ability to hold companies responsible for the content on their platforms and levy potential fines of up to 5 percent of global revenue. The bill, which was proposed this week, has yet to be passed.

Musk’s comments drew rebukes from senior Australian politicians, with Stephen Jones, Australia’s finance minister, telling national broadcaster ABC that it was “crackpot stuff” and the legislation was a matter of sovereignty.

Google is under investigation by Europe’s privacy watchdog over its processing of personal data in the development of one of its artificial intelligence models, as regulators ramp up their scrutiny of Big Tech’s AI ambitions.

Ireland’s Data Protection Commission, which is responsible for enforcing the EU’s General Data Protection Regulation, said it had launched a statutory inquiry into the tech giant’s Pathways Language Model 2, or PaLM 2.

PaLM 2 was launched in May 2023 and predates Google’s latest Gemini models, which power its AI products. Gemini, which was launched in December of the same year, is now the core model behind its text and image-generation offering.

Data centers powering the generative AI boom are gulping water and exhausting electricity at what some researchers view as an unsustainable pace. Two entrepreneurs who met in high school a few years ago want to overcome that crunch with a fresh experiment: sinking the cloud into the sea.

Sam Mendel and Eric Kim launched their company, NetworkOcean, out of startup accelerator Y Combinator on August 15 by announcing plans to dunk a small capsule filled with GPU servers into San Francisco Bay within a month. “There's this vital opportunity to build more efficient computer infrastructure that we're gonna rely on for decades to come,” Mendel says.

The founders contend that moving data centers off land would slow ocean temperature rise by drawing less power and letting seawater cool the capsule’s shell, supplementing its internal cooling system. NetworkOcean’s founders have said a location in the bay would deliver fast processing speeds for the region’s buzzing AI economy.

In recent years, the Arctic has become a magnet for climate change anxiety, with scientists nervously monitoring the Greenland ice sheet for signs of melting and fretting over rampant environmental degradation. It wasn’t always that way.

At the height of the Cold War in the 1950s, as the fear of nuclear Armageddon hung over American and Soviet citizens, ­idealistic scientists and engineers saw the vast Arctic region as a place of unlimited potential for creating a bold new future. Greenland emerged as the most tantalizing proving ground for their research.

Scientists and engineers working for and with the US military cooked up a rash of audacious cold-region projects—some innovative, many spit-balled, and most quickly abandoned. They were the stuff of science fiction: disposing of nuclear waste by letting it melt through the ice; moving people, supplies, and missiles below the ice using subways, some perhaps atomic powered; testing hovercraft to zip over impassable crevasses; making furniture from a frozen mix of ice and soil; and even building a nuclear-powered city under the ice sheet.

Most people are “very” or “extremely” concerned about the state of the natural world, a new global public opinion survey shows.

Roughly 70 percent of 22,000 people polled online earlier this year agreed that human activities were pushing the Earth past “tipping points,” thresholds beyond which nature cannot recover, like loss of the Amazon rainforest or collapse of the Atlantic Ocean’s currents. The same number of respondents said the world needs to reduce carbon emissions within the next decade.

The cost of renting cloud services using Nvidia’s leading artificial intelligence chips is lower in China than in the US, a sign that the advanced processors are easily reaching the Chinese market despite Washington’s export restrictions.

Four small-scale Chinese cloud providers charge local tech groups roughly $6 an hour to use a server with eight Nvidia A100 processors in a base configuration, companies and customers told the Financial Times. Small cloud vendors in the US charge about $10 an hour for the same setup.

The low prices, according to people in the AI and cloud industry, are an indication of plentiful supply of Nvidia chips in China and the circumvention of US measures designed to prevent access to cutting-edge technologies.
