WebAs mentioned, Earth’s climate tends to persist near the extremes—near the upper boundary of the greenhouse state or the lower boundary of the icehouse state. If global temperatures become too hot, liquid water boils and becomes steam, and if climate is too cold, liquid water freezes and becomes ice. WebToday, Earth’s climate lies near the cold end of the icehouse state, but rock bodies across the planet record that Earth was in an extreme greenhouse state in the early Cenozoic. These extremely different climates become readily apparent when comparing present organisms to those that inhabited western Wyoming during the 50-Mya extreme …
