Similarly, the possible snowball Earth of the Precambrian's Cryogenian between 580 and 850 million years ago (and which itself had a number of distinct episodes) could be related to the rise of more advanced multicellular animal life and life's colonisation of the land.

Timeline of glaciation. Appearance. Climate history over the past 500 million years, with the last three major ice ages indicated, Andean-Saharan (450 Ma), Karoo (300 Ma) and Late Cenozoic. A less severe cold period or ice age is shown during the Jurassic - Cretaceous (150 Ma). There have been five or six major ice ages in the history of Earth ...
Azolla event may have ended a long warm period 5.3–2.6: Pliocene climate became cooler and drier, and seasonal, similar to modern climates. 2.5 to present: Quaternary glaciation, with permanent ice on the polar regions, many named stages in different parts of the world

Earth formed around 4.54 billion years ago, approximately one-third the age of the universe, by accretion from the solar nebula. [ 4 ][ 5 ][ 6 ] Volcanic outgassing probably created the primordial atmosphere and then the ocean, but the early atmosphere contained almost no oxygen.
According to IPCC Sixth Assessment Report, in the last 170 years, humans have caused the global temperature to increase to the highest level in the last 2,000 years. The current multi-century period is the warmest in the past 100,000 years. [ 3 ] The temperature in the years 2011-2020 was 1.09 °C higher than in 1859–1890.
