The hands of the Doomsday Clock are closer to midnight than ever before. The Bulletin of Atomic Scientists — a nonprofit organization made up of scientists, former political leaders and security and technology experts — moved the hands of the symbolic clock 10 seconds forward, to 90 seconds to midnight. The adjustment, made in response to threats from nuclear weapons, climate change and infectious diseases such as Covid-19, is the closest the clock has been to symbolic doom since it was created more than 75 years ago. The climate crisis remains a major threat, with the Bulletin’s scientists noting that while carbon dioxide emissions fell in 2020 because of coronavirus lockdowns around the world, they rebounded to record highs in 2021 and increased again in 2022.
