WebIcehouses have major polar ice caps that calve marine icebergs. A cool greenhouse can have small polar ice caps and Alpine glaciers, but no ice sheets that calve icebergs. Glaciations in the Late Devonian, Late Eocene, and just prior to the Late Ordovician icehouse were probable cool greenhouse climates. 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.
