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 are four different theories that attempt to explain why the earths climate has changed?
The greenhouse gas theory suggests that increased levels of gases like carbon dioxide trap heat in the atmosphere, leading to a warmer climate. The Milankovitch cycles theory proposes that variations in Earth's orbit and tilt influence the amount of solar energy received by the planet, causing changes in climate. The volcanic activity theory suggests that high levels of volcanic eruptions can release gases and particles into the atmosphere, affecting the climate. The solar variability theory proposes that fluctuations in the sun's radiation output impact Earth's climate over long periods of time.
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.
What discovery convinced geoscientist that milankovitchs astronomical theory explained the major climate flucatuations of the pleistocene?
The discovery of a strong correlation between variations in Earth's orbit and the timing of glacial and interglacial periods during the Pleistocene provided convincing evidence for Milankovitch's astronomical theory. This correlation showed that changes in the Earth's orbital parameters could influence the amount and distribution of solar radiation reaching Earth, leading to major climate fluctuations.
What is the milankovich theory in terms of climate change?
Milutin Milankovitch was a Serbian astronomer and geophysicist who noted cyclic orbital periods of earth coincided with ice ages. One of these is the 26,000 year precession cycle. There is also a 100,000 year cycle and a 400,000 year cycle. The interaction between these cycles alternately warms and cools the earth via orbital forcing. Right now perihelion occurs in January, making northern winters slightly warmer than usual. Earth should be in a slightly cooling phase right now, so the current climate change is considered most likely anthropogenic instead.
What are the 3 componets of the milankovitch theory?
The three components of the Milankovitch theory are eccentricity (changes in Earth's orbit shape), axial tilt (variation in the angle of Earth's axis), and precession (wobbling of Earth's axis orientation). These factors influence the amount and distribution of solar radiation reaching Earth, contributing to long-term climate changes.

The Milankovitch theory states that ice ages are not one long cold spell and that?
they occur as part of natural climate cycles caused by changes in Earth's orbit, tilt, and precession. These variations affect how sunlight is distributed on Earth's surface, leading to long-term changes in temperature and ice volume. The theory helps explain the periodicity of ice ages over geological time scales.

What are the three parts of the Milankovitch Cycles?
A:The Milankovitch (or Milankovich) Theory describes the collective effects of changes in the earth's movements upon its climate. A cycle of precession lasts 26,000 years. At the same time, there is a cycle in which the earth's elliptical orbit rotates. The angle between Earth's rotational axis and the normal to the plane of its orbit oscillates between 22.1 and 24.5 degrees on a 41,000-year cycle. The combined effect of these and other cycles can produce a long-term cycle in the amount of warmth received from the sun. Milankovitch cycles operate over the very long term and have great value as a theory to explain ice ages and long-term changes in the climate, but are unlikely to have very much impact on the decade-century timescale. Over several centuries, it may be possible to observe the effect of these orbital parameters, however for the prediction of climate change in the twenty-first century, these changes are considered far less important than radiative forcing from greenhouse gases.

What is the theory used to explain changes in state?
The theory used to explain changes in state is the Kinetic Molecular Theory. This theory states that the state of matter is determined by the movement and energy of its particles, with changes in state occurring when the particles gain or lose energy.
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).
