I don't think the Gala Theory is needed but it does have a point. The obvious reasons for changes have been noted a good while ago.

Deforestation - known to cause climate change.Especially weather patterns. Warnings go back to the 70's.
Periods of floods. Some years ago were put mostly down to land drainage, farming. This also silts up rivers. There is also building on flood planes.
Long walks on farmland - no wild life at all in some areas.
Plagues - we have been overdue one for a very long time. That is the opinion of the people who look at this sort of thing. They happen. Animal husbandry makes them more likely.

Natural cycles such as does the gulf stream switch of at times. These factors may have been their all of the time and maybe CO2 is speeding them up. Maybe some just happen for currently unknown reasons. Talking very long periods of time the planet has not been stable.

Populations grow and grow. Can the land they need to live support them all?
