Knowledge of precise climatic events decreases as the record goes back in time, but some notable climate events are known:
* [[Faint young Sun paradox]] (start)
* [[Huronian glaciation]] (~2400 Mya Earth completely covered in ice probably due to [[Great Oxygenation Event]])
* Later Neoproterozoic [[Snowball Earth]] (~600 Mya, precursor to the [[Cambrian Explosion]])
* [[Andean-Saharan glaciation]] (~450 Mya)
* [[Carboniferous Rainforest Collapse]] (~300 Mya)
* [[Permian–Triassic extinction event]] (251.9 Mya)
* [[Anoxic event|Oceanic anoxic events]] (~120 Mya, 93 Mya, and others)
* [[Cretaceous–Paleogene extinction event]] ({{period start|Paleogene}} Mya)
* [[Paleocene–Eocene Thermal Maximum]] ([[Paleocene]]–[[Eocene]], 55Mya)
* [[Last Glacial Maximum]] (~23,000 BCE)
* [[Younger Dryas]]/Big Freeze (~11,000 BCE)
* [[Holocene climatic optimum]] (~7000–3000 BCE)
* [[Extreme weather events of 535–536]] (535–536 CE)
* [[Medieval Warm Period]] (900–1300)
* [[Little Ice Age]] (1300–1800)
* [[Year Without a Summer]] (1816)
