The Milankovitch cycles consist of the Procession or Wobble of the axis (24,000 years); the Eccentricity (100,000 years); and the Tilt (41,000 years). The Procession determines if the earth is closest or farthest away from the sun in winter; the Eccentricity determines how great the solar insolation will be when the earth is close to the sun; and the Tilt determines how extreme seasons will be. The larger, the tilt the more extreme. All these cycles in concert provide forcing that has led to periods of glaciation in the past. Feedback cycles are important also in allowing winter-time snow to last through the Northern Hemisphere summer above 65 N latitude.
Bottom line - astronomical forcing was one of the primary drivers of creating past ice ages (which are large changes in climate).
What else can I help you with?
Is global warming or the sun's cycle or the milankovitch theory or the asteroid impact considered an effect on climate change?
Scientists conclude that the main factor in climate change is the present global warming from the burning of fossil fuels(coal, oil and natural gas) and deforestation (cutting down trees which previously removed carbon dioxide (CO2) from the atmosphere).
Which natural cause of climate change deals with changes to Earth's orbit around the Sun?
The natural cause of climate change that deals with changes to Earth's orbit around the Sun is known as Milankovitch cycles. These cycles involve variations in the Earth's orbit, tilt, and precession, which can affect the amount and distribution of solar energy received by the Earth, ultimately influencing climate patterns over long timescales.
What are the possible causes of the ice age?
The causes of past ice ages are mainly attributed to variations in Earth's orbit and tilt known as Milankovitch cycles. These cycles affect the amount and distribution of sunlight Earth receives. Other contributing factors include volcanic eruptions, changes in greenhouse gas concentrations, and feedback mechanisms within the Earth's climate system.
What is the name for the cycles resulting from changes in earths movements and that may cause ice ages?
The cycles resulting from changes in Earth's movements are called Milankovitch cycles. These changes in Earth's orbit and axial tilt can affect the amount and distribution of sunlight reaching the Earth's surface, potentially leading to ice ages.
What has caused repeating 100000-year cycles of ice ages in the past?
Changes in Earth's orbit and axial tilt, known as Milankovitch cycles, are responsible for triggering the repeating 100,000-year cycles of ice ages. These variations affect the amount of solar radiation reaching Earth's surface, leading to periods of glaciation and interglacial periods.
Why don't global warming experts reference the Milankovitch cycles?
Because Milankovitch cycles cannot explain climate variability over the time scale that we're interested in predicting climate. Milankovitch cycles can explain large variations in climate over very long time scales, scales of thousands of years. Milankovitch cycles do not explain variability in climate on the scales of hundreds or tens of years. Variability at smaller time scales is driven by other factors, such as carbon dioxide (CO2) and other greenhouse gas concentrations.

How might the Milankovitch cycles affect the global climate?
Milankovitch cycles are orbital cycles affecting earth's insolation. There have been a long series of ice ages closely tied to these orbital cycles, and in fact earth should even now be ever so slightly and gradually cooling towards another ice age which should begin in about 50,000 years. Not particularly soon. The fact earth continues warming at a rapid rate suggests significant environmental impact from some outside source.

Other contributing factors include volcanic eruptions, changes in greenhouse gas concentrations, and feedback mechanisms within the Earth's climate system.
How does earth's orbit influence climate?
Earth's orbit influences climate primarily through variations in its shape (eccentricity), tilt (obliquity), and axial precession. These changes affect the distribution and intensity of sunlight received by different parts of the planet, leading to cycles of glacial and interglacial periods, known as Milankovitch cycles. For instance, increased tilt can enhance seasonal contrasts, while a more circular orbit can lead to milder climate variations. Together, these orbital changes significantly impact long-term climate patterns and trends.

What does the milankovitch theory explain?
The Milankovitch theory was created by Milutin Milankovitch in the early 1900's while under house arrest. He calculated the temperature cycles based on the tilt of our planet, the gravitional pull of other planets and other natural issues that occur on roughly 26,000, 48,000 and 100,000 year cycles. His calculations coincided with the derived temperatures that were taken from the Lake Vostok glacial samples. One of the more interesting thngs that he theorized was that temperatures of the planet would crest when all the large planets were on one side of the sun and causing our orbit to be least circular. Under this theory, the planets natural temperatures should be cresting roughly about now. He developed these temperature cycles and theories without taking into account CO2 measurements.
Who is Milankovic?
Milutin Milanković was a Serbian mathematician, astronomer, and geophysicist known for his work on the mathematical theory of climate and the study of Earth's long-term climate variations. He proposed the theory of changes in Earth's orbit and tilt as the key drivers of ice ages in what is known as the Milankovitch cycles. His work revolutionized the understanding of Earth's past climate changes.
What has caused repeating 100000-year cycles of ice ages in the past?
Changes in Earth's orbit and axial tilt, known as Milankovitch cycles, are responsible for triggering the repeating 100,000-year cycles of ice ages. These variations affect the amount of solar radiation reaching Earth's surface, leading to periods of glaciation and interglacial periods.
How do scientists think earths orbit relates to an ice age?
Variations in the Earth's orbit around the sun are called Milankovitch cycles. Scientist do not believe that Milankovitch cycles can start or end an ice age. Each cycle runs a different length and the variations in the cycles reinforce their effects or cancel them.
How do climate change affect biodiversity?
Changes in Carbon, Nitrogen, and Phosphorous cycles can affect the health and variety of organisms that live in an ecosystem
