World's Oceans Fail Key Health Check As Acidity Crosses Critical Threshold For Marine Life

3 months ago
An anonymous reader quotes a report from The Guardian: The world's oceans have failed a key planetary health check for the first time, primarily due to the burning of fossil fuels, a report has shown. In its latest annual assessment, the Potsdam Institute for Climate Impact Research said ocean acidity had crossed a critical threshold for marine life. This makes it the seventh of nine planetary boundaries to be transgressed, prompting scientists to call for a renewed global effort to curb fossil fuels, deforestation and other human-driven pressures that are tilting the Earth out of a habitable equilibrium. The report, which follows earlier warnings about ocean acidity, comes at a time of recordbreaking ocean heat and mass coral bleaching. Oceans cover 71% of the Earth's surface and play an essential role as a climate stabilizer. The new report calls them an "unsung guardian of planetary health", but says their vital functions are threatened. The 2025 Planetary Health Check noted that since the start of the industrial era, oceans' surface pH has fallen by about 0.1 units, a 30-40% increase in acidity, pushing marine ecosystems beyond safe limits. Cold-water corals, tropical coral reefs and Arctic marine life are especially at risk. This is primarily due to the human-caused climate crisis. When carbon dioxide from oil, coal and gas burning enters the sea, it forms carbonic acid. This reduces the availability of calcium carbonate, which many marine organisms depend upon to grow coral, shells or skeletons. Near the bottom of the food chain, this directly affects species like oysters, molluscs and clams. Indirectly, it harms salmon, whales and other sea life that eat smaller organisms. Ultimately, this is a risk for human food security and coastal economies. Scientists are concerned that it could also weaken the ocean's role as the planet's most important heat absorber and its capacity to draw down 25-30% of the carbon dioxide in the atmosphere. Marine life plays an important role in this process, acting as a "biotic bump" to sequester carbon in the depths. In the report, all of the other six breached boundaries -- climate change, biosphere integrity, land system change, freshwater use, biogeochemical flows, and novel entities -- showed a worsening trend. But the authors said the addition of the only solely ocean-centerd category was a alarming development because of its scale and importance.

Intel Approaches Apple For Potential Investment Amid Struggles

3 months ago
Intel has approached Apple about a possible investment and closer collaboration, following recent multibillion-dollar deals with Nvidia, the U.S. government, and SoftBank to stabilize the struggling chipmaker. Reuters reports: The iPhone maker and Intel have also discussed how to work more closely together, the report said, adding that the talks are at an early stage and may not lead to an agreement. Shares of Intel closed 6% higher after the news. [...] Striking lucrative partnerships and persuading outside clients to use Intel's factories remain key to its future. Intel has also reached out to other companies about possible investments and partnerships, according to the Bloomberg News report. The reported investment from Apple would come as another vote of confidence for Intel - Apple had been a longtime customer of Intel before it transitioned to using its own custom-designed silicon chips in 2020. For Apple, which relies heavily on Intel's rival TSMC to manufacture its chips, the new partnership would allow it to diversify its chipmaking supplier base - a move that would be valuable if geopolitical risks in Taiwan worsen due to China's role in the region. It would also help Apple improve its relationship with U.S. President Donald Trump, by showing that it is investing in the United States - while much of Apple's supply chain remains international, the company has committed about $600 billion to domestic initiatives over the next four years.

Qualcomm Announces Snapdragon X2 Elite and Extreme For Windows PCs

3 months ago
Qualcomm unveiled its Snapdragon X2 Elite and Extreme chips, claiming they're the "fastest and most efficient processors for Windows PCs." Built on 3nm with up to 18 cores and a 5GHz Arm CPU boost, the chips promise 31% more CPU power, up to 2.3x GPU performance, stronger AI processing, and "multi-day battery life," with devices expected in the first half of 2026. The Verge reports: There's also a new 80 TOPS Hexagon NPU, for AI tasks, that offers 37 percent more performance with a 16 percent power consumption improvement, the company claims. Qualcomm's characterizing all of this as a "legendary leap in performance," claiming the Elite Extreme in particular offers "up to 75 percent faster CPU performance" at the same power. But it doesn't say who the competition is, or which chip it was up against, at least not in the press release. And while Qualcomm claims these power savings will lead to "multi-day battery life," that's also what the company said about last year's Snapdragon X Elite.
