I like this idea. From what I remember of Jung, the archetypes are based on constants of human psychology. Would 'impending catastrophe as a spur for change' map onto any of the archetypes Jung talked about? Even if it doesn't, myths of impending catastrophe is a recurring theme in human society. The archetype could be that there is a 'sickness' in the world, but this hasn't historically been a spur for change.

I have also seen climate change being used as an argument against change. In the lead-up to the Brexit vote, there were a lot of 'news' articles warning of the various catastrophes that Brexit would cause. One of these articles warned that Brexit would mean the UK would no longer be part of a particular climate change pact, or certain organisations in the UK would lose funding.

I see climate change as a dual concept - the idea of nature as a fragile and global being/phenomenon, and the incoming threat to this caused by climate change. Could it be two archetypes? Or the first concept merely a fact that increasing scientific knowledge and globalism has made us aware of.
