On the subject of weather and climate change, I'm wondering if there's a word that sums up "the worst case scenario"? At the moment I'm stuck on amplitude, as an expression of the field of/variations in outcomes... But I'm looking for something better! Ideally I'm looking for a tidy expression signifying maximum possible effect: The something something... (Not apocalypse etc) I know it exists, I just can't put my finger on it.
Many thanks for any help.
