Doomsday clock stays at two minutes to midnight as crisis now 'new abnormal'

Warning that 'We are like passengers on the Titanic, ignoring the iceberg ahead' in face of nuclear arms and climate change threats

The risk to global civilisation from nuclear weapons and climate change remains at an all-time high, according to a group of prominent US scientists and former officials, who said the world's predicament had become the "new abnormal".

The Bulletin of the Atomic Scientists announced that its symbolic "doomsday clock", unveiled every year, was stuck at two minutes to midnight, the same as last January. The only other time the Bulletin has judged the world as being this close to catastrophe was 1953, in the early volatile stages of the cold war.
