The Stenian Era, part of the Neoproterozoic Eon, lasted from about 1200 to 1000 million years ago. During this time, the Earth experienced significant climatic fluctuations, with evidence suggesting periods of both glaciation and warmer temperatures. The presence of large landmasses and the gradual increase in atmospheric oxygen levels likely influenced these climatic changes. Additionally, the era is marked by the development of more complex life forms, indicating a dynamic and evolving environment.

The climate before the Mesozoic period/era was a relatively warm climate. The Mesozoic Era was an interval of geological time from about 252 to 66 million years ago and is also called the Age of Reptiles.

The Paleozoic Era, which lasted from about 541 to 252 million years ago, experienced a range of climates, from tropical to polar. Early in the era, during the Cambrian and Ordovician periods, the climate was generally warm and humid, supporting diverse marine life. As the era progressed, particularly during the late Paleozoic, significant glaciation occurred, especially in the southern hemisphere during the Carboniferous and Permian periods. This fluctuation in climate contributed to the evolution and extinction of many species throughout the era.

The climate of the Cenozoic era was generally cooler and more variable compared to the relatively warm and stable climate of the Mesozoic era. The Cenozoic era experienced significant fluctuations in temperature, including periods of glaciation, whereas the Mesozoic era was characterized by a more uniform greenhouse climate.
