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.
At the beginning of the cenezoic era, the climate was humid and mild. However, once the ice age occured and mammoths and saber toothed tigers thrived, animals such as Diatryma would not adapt to the very cold climate of the ice ages. Humans evolved and the climate gradually got warmer. Today, global warming is making an impact and taking a toll so the next era will probably be much hotter than the climate today.

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.
