This month, the Bulletin of the Atomic Scientists (BAS) will update the Doomsday Clock, which measures humanity's proximity to global catastrophe. Last year, the clock remained at 90 seconds to midnight, the closest it has been since the creation of the atomic bomb. Experts warn that the risk of nuclear war is now 'far too high', with tensions between the West and China increasing and a war still raging in Ukraine. The BAS also highlights other threats such as climate change, the rise of powerful AIs, and the spread of genetic engineering technologies.
