Modern climate system is established 2.7 mya

Glaciation in the northern hemisphere intensified and sustained and extensive continental glaciation of both hemispheres occurs - our modern climate system is established with a variation from warm interglacials to cold glacial periods every ~40 kyr caused by subtle changes in the Earth's orbit. The Genus Homo (to which humans belong) first appears in the geological record at around this time.
