Geological changes actually happen fast enough that one can observe some of them in a human lifetime. Continents drift at a rate of about 2cm per year. Over fifty years, it becomes noticeable when the pools in the sea where you played as a child are now 1 meter deeper or shallower.
In other places old famous harbours may now be dry and a few km inland, like Troy or Cesarea - or under water like Cleopatra's at Alexandria.
These slow, but inexorable movements eventually alter the sea currents which can cause sudden changes in climate.
Note that we are currently still in an ice age. The Quaternary Ice Age will only end when Greenland and Antarctica are melted and the whole globe has become tropical again, as it normally is. Ice ages are brief - a few million years, while the warm periods like the Mesozioc lasts hundreds of millions of years. Our whole human existence has been in an Ice Age.
