500 million years of climate change Ice core data for the past 400,000 years, with the present at right. Note length of glacial cycles averages ~100,000 years. Blue curve is temperature, green curve is CO 2, and red curve is windblown glacial dust (loess). Scale: Millions of years before present, earlier dates approximate.
[118] [119] [120] Scientifically, global warming refers only to increased surface warming, while climate change describes both global warming and its effects on Earth's climate system, such as precipitation changes. [117] Climate change can also be used more broadly to include changes to the climate that have happened throughout Earth's history ...

The "Composite Plus Scaling" (CPS) method is widely used for large-scale multiproxy reconstructions of hemispheric or global average temperatures; this is complemented by Climate Field Reconstruction (CFR) methods which show how climate patterns have developed over large spatial areas, making the reconstruction useful for investigating natural ...
Ice age – Period of long-term reduction in temperature of Earth's surface and atmosphere; Last Glacial Period – Period of major glaciations of the Northern Hemisphere (115,000–12,000 years ago) Thermal history of Earth; Geologic temperature record – Very long term changes in Earth's temperature; List of periods and events in climate history
500 million years of climate change [7] The Phanerozoic eon, encompassing the last 542 million years and almost the entire time since the origination of complex multi-cellular life, has more generally been a period of fluctuating temperature between ice ages, such as the current age, and "climate optima", similar to what occurred in the ...
Throughout Earth's climate history (Paleoclimate) its climate has fluctuated between two primary states: greenhouse and icehouse Earth. [1] Both climate states last for millions of years and should not be confused with the much smaller glacial and interglacial periods, which occur as alternating phases within an icehouse period (known as an ice age) and tend to last less than one million years ...
End of the pre-Boreal period of European climate change. Pollen Zone IV Pre-boreal, associated with juniper, willow, birch pollen deposits. Neolithic era begins in Ancient Near East. Evidence of the earliest settlement in Jericho; In Antarctica, long-term melting of the Antarctic ice sheets is commencing.
