According to a model of the geological forces shaping the climate over the past 420 million years, reaching such ice house temperatures requires a combination of rapid rock erosion removing carbon dioxide from the atmosphere and less CO2-releasing volcanic activity.Despite record high temperatures on brief human timescales today, Earths climate is currently colder than usual. When you look back in the geological past and you try to
