The Earth’s climate is not easy to cool. This is especially true if you want to make it cool enough to form an ice cap. According to a model of geological forces that have been shaping climates over the past 420 million years, reaching temperatures like this “ice house” involve removing carbon dioxide from the atmosphere and reducing volcanic activity in CO2 release. A combination of rapid rock erosion is required.
Despite record high temperatures on today’s short human timescales, the Earth’s climate is currently colder than usual. “Looking back at the geological past, when you try to…
