Scientists from the BPA have said the world is more dangerous in 2017. BPA scientists are experts on nuclear weapons, climate change and new technology. They set the Doomsday Clock, which shows how close the world is to disaster. The BPA changed the clock's time to two-and-a-half minutes to midnight. This is the closest it has been to midnight (the Apocalypse) since 1953, when the USA and Russia tested hydrogen bombs.
The BPA said President Donald Trump's views on climate change, nuclear weapons, immigration and terrorism added to global risk. It warned: "The probability of global catastrophe is very high, and the actions needed to reduce the risks of disaster must be taken very soon." The BPA chief hoped the clock's new time would help people around the world to, "hold their leaders responsible for delivering a safer and healthier planet".
