Volcanic eruptions typically cool the Earth’s surface by releasing aerosols which reflect sunlight. However, a recent eruption released a significant amount of water vapor-a strong greenhouse gas-into the stratosphere with unknown consequences. This study examines the aftermath of the eruption and reveals that surface temperatures across large regions of the world increased by over 1.5°C for several years, although some areas experience cooling close to 1°C. Additionally, the research suggests a potential connection between the eruption and sea surface temperatures in the tropical Pacific, which warrants further investigation.

Chipmakers have announced more than $200bn-worth of investments in America. By 2025 American chip factories will be churning out 18% of the world’s leading-edge chips. TSMC is splurging $40bn on two fabs in Arizona. Samsung of South Korea is investing $17bn in Texas. Intel, America’s chipmaking champion, will spend $40bn on four fabs in Arizona and Ohio. If all the planned investments materialise, America will produce enough cutting-edge chips to meet barely a third of domestic demand for these. Apple will keep sourcing high-end processors for its iPhones from Taiwan. So, in all likelihood, will America’s nascent AI-industrial complex.
