True.
It was during the Cenozoic Era that a great Ice Age began. At the peak of the Ice Age, at least 32% of the Earth was covered by huge glaciers, thousands of feet thick. Today 5 million square miles of our planet remain covered in glaciers.

at least 3 of varying degrees.,
Over the course of our planet's history, there have been many ice ages and periods of global warming. The last one of the ice ages started about 110.000 years ago and lasted until about 10,000 BC.
Over time, their have been many ice ages

It is not known exactly how many ice ages Earth has experienced, but a reasonable estimate would be at least 20 known events and probably many more.
There are a few planets which have ice. Earth has ice. Mars is believed to contain ice far underneath its surface. Pluto which is no longer classified as a planet has a surface which is completely frozen.
There have been many ice ages in the Phanerozoic apart from the present one, in fact there were also many ice ages in the Proterozoic so it is not a very unusual thing to happen.
no Pluto is the ice planet
There have been five major ice ages in Earth's history: the Huronian, Cryogenian, Andean-Saharan, Karoo Ice Age and the Quaternary glaciation. There have been many "little ice ages" in various parts of the world, however, where the climate was unusually cold for several years at a time.
