While originally the Clock represented the threat of the power struggle between superpowers, it's important to note that factors such as climate change and bioterrorism are now factored into setting the Clock. The Clock's current position was explained as follows:

'On 23 January 2020, the Clock was moved further, to 100 seconds (1 minute 40 seconds) before midnight, meaning that the Clock's status today is the closest to midnight since the Clock's start in 1947. The Bulletin' executive chairman, Jerry Brown, said "the dangerous rivalry and hostility among the superpowers increases the likelihood of nuclear blunder... Climate change just compounds the crisis".'

I think many can appreciate that the lack of appreciable action on climate change is at least as worrisome as the the threat of a nuclear exchange and it is looking increasingly likely we will miss our 1.5-2 degree targets.
