Question

A disaster is a sudden_ that may cause displacement of great number of people ​

Answer 1

Explanation:

climate change is expected to increase the number of sudden-onset disasters caused by natural hazards and as a consequence we can expect more disaster-induced displacement around the world. As experts gathered last week for a meeting of the KNOMAD working group on environmental change and migration, it was clear that while there is much that we know, there is even more we don’t know about the nature of such displacement.
