Many of these theories include some event that caused great changes to the atmosphere and environment that was impossible to adopt to.

This may be evidence for the dust cloud in 2 above. But this connection has to be demonstrated, not just assumed. The original hypothesis is the basis for several subsequent variations on the theme that a large extraterrestrial object collided with the Earth, its impact throwing up enough dust to cause the climatic change.
