We’ve all been told the story of what wiped out the dinosaurs – a giant meteor careers down from the sky, crashes into Earth and bang! The rest is history. But what if that wasn’t the whole story? A new study suggests there may have been more to it than just an asteroid – and it involves climate change. A chain of huge volcanic eruptions which eventually cooled the planet an alarming amount may have been partially to blame, according to research. The study, published in Science Advances and co-authored by Don Baker, a professor in McGill University's Department of Earth and Planetary Sciences, suggests that this might be the case. The researchers looked into volcanic eruptions at the Deccan Traps, a huge, rugged plateau that formed when molten lava solidified and turned to rock. The plateau dates back to around 66-65m years ago, when magma from deep inside Earth erupted to the surface. That just so happens to be around the time when scientists think the dinosaurs met their demise. Baker’s team suggest that the eruptions produced a staggering 1m cubic kilometres of lava, which then turned into rock, which may have played a key role in cooling the global climate around 65m years ago. The scientists say it’s all to do with how much sulphur and fluorine was pumped into the atmosphere as a result of the eruptions. Incredibly, they found the event could have sparked a drop in temperature all around the world, dubbed a “volcanic winter”. Baker said: “Our research demonstrates that climatic conditions were almost certainly unstable, with repeated volcanic winters that could have lasted decades, prior to the extinction of the dinosaurs. “This instability would have made life difficult for all plants and animals and set the stage for the dinosaur extinction event. “Thus our work helps explain this significant extinction event that led to the rise of mammals and the evolution of our species.” The scientists worked it out using new chemical techniques developed at McGill to measure how much sulphur is in the rock formations which came about at the time, then from that, figuring out how much went into the atmosphere. The paper is titled “Recurring volcanic winters during the latest Cretaceous: Sulfur and fluorine budgets of Deccan Traps lavas.” How to join the indy100's free WhatsApp channel Sign up to our free indy100 weekly newsletter Have your say in our news democracy.

One of the “godfathers” of artificial intelligence (AI) has said he feels “lost” as experts warned the technology could lead to the extinction of humanity. Professor Yoshua Bengio told the BBC that all companies building AI products should be registered and people working on the technology should have ethical training. It comes after dozens of experts put their name to a letter organised by the Centre for AI Safety, which warned that the technology could wipe out humanity and the risks should be treated with the same urgency as pandemics or nuclear war. Prof Bengio said: “It is challenging, emotionally speaking, for people who are inside (the AI sector). It's exactly like climate change. We've put a lot of carbon in the atmosphere. And it would be better if we hadn't, but let's see what we can do now Professor Yoshua Bengio “You could say I feel lost. But you have to keep going and you have to engage, discuss, encourage others to think with you.” Senior bosses at companies such as Google DeepMind and Anthropic signed the letter along with another pioneer of AI, Geoffrey Hinton, who resigned from his job at Google earlier this month, saying that in the wrong hands, AI could be used to to harm people and spell the end of humanity. Experts had already been warning that the technology could take jobs from humans, but the new statement warns of a deeper concern, saying AI could be used to develop new chemical weapons and enhance aerial combat. AI apps such as Midjourney and ChatGPT have gone viral on social media sites, with users posting fake images of celebrities and politicians, and students using ChatGPT and other “language learning models” to generate university-grade essays. But AI can also perform life-saving tasks, such as algorithms analysing medical images like X-rays, scans and ultrasounds, helping doctors to identify and diagnose diseases such as cancer and heart conditions more accurately and quickly. Last week Prime Minister Rishi Sunak spoke about the importance of ensuring the right “guard rails” are in place to protect against potential dangers, ranging from disinformation and national security to “existential threats”, while also driving innovation. He retweeted the Centre for AI Safety’s statement on Wednesday, adding: “The government is looking very carefully at this. Last week I stressed to AI companies the importance of putting guardrails in place so development is safe and secure. But we need to work together. That’s why I raised it at the @G7 and will do so again when I visit the US.” Prof Bengio told the BBC all companies building powerful AI products should be registered. “Governments need to track what they’re doing, they need to be able to audit them, and that’s just the minimum thing we do for any other sector like building aeroplanes or cars or pharmaceuticals,” he said. “We also need the people who are close to these systems to have a kind of certification… we need ethical training here. Computer scientists don’t usually get that, by the way.” Prof Bengio said of AI’s current state: “It’s never too late to improve. “It’s exactly like climate change. We’ve put a lot of carbon in the atmosphere. And it would be better if we hadn’t, but let’s see what we can do now.” We don't quite know how to understand the absolute consequences of this technology Professor Sir Nigel Shadbolt Oxford University expert Sir Nigel Shadbolt, chairman of the London-based Open Data Institute, told the BBC: “We have a huge amount of AI around us right now, which has become almost ubiquitous and unremarked. There’s software on our phones that recognise our voices, the ability to recognise faces. “Actually, if we think about it, we recognise there are ethical dilemmas in just the use of those technologies. I think what’s different now though, with the so-called generative AI, things like ChatGPT, is that this is a system which can be specialised from the general to many, many particular tasks and the engineering is in some sense ahead of the science. “We don’t quite know how to understand the absolute consequences of this technology, we all have in common a recognition that we need to innovate responsibly, that we need to think about the ethnical dimension, the values that these systems embody. “We have to understand that AI is a huge force for good. We have to appreciate, not the very worst, (but) there are lots of existential challenges we face… our technologies are on a par with other things that might cut us short, whether it’s climate or other challenges we face. “But it seems to me that if we do the thinking now, in advance, if we do take the steps that people like Yoshua is arguing for, that’s a good first step, it’s very good that we’ve got the field coming together to understand that this is a powerful technology that has a dark and a light side, it has a yin and a yang, and we need lots of voices in that debate.” Read More Charity boss speaks out over ‘traumatic’ encounter with royal aide Ukraine war’s heaviest fight rages in east - follow live Cabinet approves Irish involvement in cyber-threat network Trust and ethics considerations ‘have come too late’ on AI technology Mitigating ‘extinction’ from AI should be ‘global priority’, experts say

Southampton boss Russell Martin says James Ward-Prowse and Romeo Lavia will be involved in Friday night’s Sky Bet Championship opener at Sheffield Wednesday “as it stands”. Both players have been linked with an exit from St Mary’s this summer following last season’s relegation from the Premier League, with Ward-Prowse linked with Fulham and West Ham and Lavia attracting bids from Liverpool. But a transfer for either men have yet to materialise and Martin will utilise them at Hillsborough. “Both will be involved tomorrow night, as it stands, I dont know what will change between now and then,” he said in his pre-match press conference. “Do I think they will be Southampton players at the end of the window? I have not got a clue. What I hope, what I think, is probably very different. “It would be pointless for me to come out and say, ‘I think they will be here, I don’t think they’ll be here’, because ultimately I have no control over that. “If they are both not here, or one is not here it is because the club and the player think they have something which is beneficial for everyone. “That will be the case, that is why it has dragged on and why it will probably continue to drag on. But while they have been here, both have been great and both will be involved tomorrow night. As it stands.” Kamaldeen Sulemana is injured and will miss the trip to South Yorkshire, while Sekou Mara is a doubt.
