Knowledge of precise climatic events decreases as the record goes further back in time. The timeline of glaciation covers ice ages specifically, which tend to have their own names for phases, often with different names used for different parts of the world. The names for earlier periods and events come from geology and paleontology.
Following is a comparison of the growth of cycle 25 versus cycle 24, using the 13-month sunspot averages, beginning with the months of the respective minimums. Numbers in brackets for cycle 25 indicate the minimum possible value for that month, assuming there are no more sunspots between now (Jan 3, 2024) and six months after the end of the ...
The names system has mostly been phased out by professionals. It is now more common for researchers to refer to the periods by their marine isotopic stage number. [ 10 ] For example, there are five Pleistocene glacial/interglacial cycles recorded in marine sediments during the last half million years, but only three classic glacials were ...
Milankovitch cycles may have also contributed [11] Paleogene: Eocene–Oligocene extinction event: 33.9 Ma: Multiple causes including global cooling, polar glaciation, falling sea levels, and the Popigai impactor [12] Cretaceous: Cretaceous–Paleogene extinction event: 66 Ma
Milankovitch cycles describe the collective effects of changes in the Earth's movements on its climate over thousands of years. The term was coined and named after the Serbian geophysicist and astronomer Milutin Milanković .

Glacials and interglacials refer to the 100,000-year cycles associated with Milankovitch cycles, and stadials and interstadials are defined by the actual oxygen-isotope temperature record. List of stadials and interstadials
