In recent Earth history, climate has varied following ~100,000 year, glacial-interglacial cycles with higher and lower temperatures and greenhouse gas concentrations. During the coldest glacial conditions, global mean temperatures were about 5 \u00b0C cooler than present with about half as much carbon dioxide in the atmosphere.
