The so-called “Cambrian Explosion” was more than 500 million years ago. About 700 million years ago there was possibly a very big ice age which covered most of the earth for a very long time.
The latest ice age is the one we are in now which started only about 2.6 million years ago and has been composed of periodic glaciations interspersed with warmer times such as now. The last glaciation ended about 10,000 years ago depending on where on earth you live.
