Earth was once hit by an extreme solar storm that would devastate human civilisation if it happened today, tree rings show. Scientists were able to piece together the solar storm from ancient tree rings that were found in the French alps, and showed evidence of a dramatic spike in radiocarbon levels some 14,300 years ago. That spike was the result of a massive solar storm, the biggest ever found by scientists. If a similar event happened today, it could knock the power grid offline for months and destroy the infrastructure we rely on for communications, scientists have warned. The researchers behind the new study have urged that the extreme nature of the newly discovered event should be a warning for the future. “Extreme solar storms could have huge impacts on Earth. Such super storms could permanently damage the transformers in our electricity grids, resulting in huge and widespread blackouts lasting months,” said Tim Heaton, professor of applied statistics in the School of Mathematics at the University of Leeds. “They could also result in permanent damage to the satellites that we all rely on for navigation and telecommunication, leaving them unusable. They would also create severe radiation risks to astronauts.” Further work is needed to ensure that the world is protected from similar events happening again, scientists said. And more research is required to actually understand how and why they might happen. Scientists have found nine extreme solar storms, or Miayake Events, that happened in the last 15,000 years. The most recent of them happened in the years 993 AD and 774 AD, but the newly found one was twice as powerful as those. Researchers do not know exactly what happened during those Miyake Events, and studying them is difficult because they can only be understood indirectly. That makes it difficult for scientists to know how and when they might happen again, or if it is even possible to predict them. “Direct instrumental measurements of solar activity only began in the 17th century with the counting of sunspots,” said Edouard Bard, professor of climate and ocean evolution at the Collège de France and CEREGE. “Nowadays, we also obtain detailed records using ground-based observatories, space probes, and satellites. “However, all these short-term instrumental records are insufficient for a complete understanding of the Sun. Radiocarbon measured in tree-rings, used alongside beryllium in polar ice cores, provide the best way to understand the Sun’s behaviour further back into the past.”  The largest solar storm that scientists were able to actually observe and study happened in 1859, and is known as the Carrington Event. It caused vast disruption to society, destroying telegraph machines and creating a bright aurora so bright that birds behaved as if the Sun was rising. The Miayake Events like the newly found storm would have been vastly more powerful, however. They were discovered by slicing ancient trees that are becoming fossils into tiny rings, and then analysing the radiocarbon that was present in them. Their work is published in a new article, ‘A radiocarbon spike at 14,300 cal yr BP in subfossil trees provides the impulse response function of the global carbon cycle during the Late Glacial’, in the journal The Royal Society’s Philosophical Transactions A: Mathematical, Physical and Engineering Sciences.

Disney has launched a new, cheaper subscription of its streaming service, with ads. The company will let subscribers pay £4.99 for the service if they are willing to have advertising injected at the start of films and inside TV shows. The advertising will be limited and users will see how long those ads are going to last, the company. Disney is just the latest in a range of subscription services, such as Netflix, to launch a cheaper version of the streaming service that is supported by advertising. The changes come amid a cost of living crisis and increasing competition for TV streaming subscriptions. As well as seeing ads, users on the new cheaper tier will be limited to watching two streams at once on one subscription, and will not be able to download offline. Netflix launched its ad-supported tier with similar limits, though it has restricted them somewhat in the time since. On Disney+, the more expensive ad-free tiers include the standard package at £7.99, or £79.90 annually, which has the same video and audio quality as the lower level but allows for downloads on up to 10 devices, while the premium model at £10.99, or £109.90, has improved video and audio quality and allows four devices to watch concurrently. The streaming giant has a host of series including The Bear, Elemental, and Coleen Rooney: The Real Wagatha Story. It also launched the new series following the Kardashian-Jenner family last year, titled The Kardashians, which follows on from its predecessor, Keeping Up With The Kardashians, in documenting the personal lives and business ventures of the siblings. General manager of Disney+ Europe, Middle East and Africa (EMEA), Luke Bradley Jones, said: “Today’s launch represents a significant milestone for Disney+ in the UK, offering customers the flexibility to select a plan that suits their needs and budget. “All of our customers can enjoy a wide range collection of award-winning original TV series and blockbuster movies, including FX’s The Bear, Elemental, and Coleen Rooney: The Real Wagatha Story, along with fan favourites like Season 2 of Marvel Studios’ Loki and the latest series of The Simpsons and Grey’s Anatomy.” Deborah Armstrong, country manager of the UK and Ireland for GM Media Networks and advertising EMEA, said: “Disney+ offers advertisers a prime opportunity to join our premium streaming platform, featuring our beloved brands and an exceptional line-up of movies and TV series. “The response from our clients and agencies has been overwhelmingly positive, firmly showcasing the quality of our content and the strong bond our brands share with audiences worldwide. “We’re partnering with a fantastic range of brands in all markets right from day one.” Additional reporting by agencies
