The oldest reference for Milankovitch cycles is: Milankovitch M (1930). Mathematische Klimalehre und Astronomische Theorie der Klimaschwankungen. Handbuch der Klimatologie. Vol. 1 Teil A. von Gebrüder Borntraeger. OCLC 490063906. Tying celestial mechanics to Earth's ice age (Physics Today 73 (5), Maslin M. A. 01 May 2020)
δ 18 O, a proxy for temperature, for the last 600,000 years (an average from several deep sea sediment carbonate samples) [a]. The 100,000-year problem (also 100 ky problem or 100 ka problem) of the Milankovitch theory of orbital forcing refers to a discrepancy between the reconstructed geologic temperature record and the reconstructed amount of incoming solar radiation, or insolation over ...
The arrangements of land masses on the Earth's surface are believed to reinforce the orbital forcing effects. Comparisons of plate tectonic continent reconstructions and paleoclimatic studies show that the Milankovitch cycles have the greatest effect during geologic eras when landmasses have been concentrated in polar regions, as is the case today.
Astronomical cycles (also known as Milankovitch cycles) are variations of the Earth's orbit around the Sun due to the gravitational interaction with other masses within the Solar System. [1] Due to this cyclicity, solar irradiation differs through time on different hemispheres and seasonality is affected. These insolation variations have ...
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
The astronomical components, discovered by the Serbian geophysicist Milutin Milanković and now known as Milankovitch cycles, include the axial tilt of Earth, the orbital eccentricity (or shape of the orbit), and the precession (or wobble) of Earth's rotation. The tilt of the axis tends to fluctuate from 21.5° to 24.5° and back every 41,000 ...
The shape of Earth's orbit around the Sun affects the Earth's climate. Over a 100,000 year cycle, Earth oscillates between having a circular orbit to having a more elliptical orbit. [24] From 2.58 million years ago to about 1.73 million ± 50,000 years ago, the degree of axial tilt was the main cause of glacial and interglacial periods. [24]
The second contribution is the explanation of Earth's long-term climate changes caused by changes in the position of the Earth in comparison to the Sun, now known as Milankovitch cycles. This partly explained the ice ages occurring in the geological past of the Earth, as well as the climate changes on the Earth which can be expected in the future.
