Hays is probably best known as a co-author of the 1976 paper in " eccentricity, axial tilt, and precession around the Sun ( see Milankovitch cycles ).
32.
Therefore, the appearance of cold surface water in the east equatorial pacific around 3 million years ago may have contributed to global cooling and modified global climate response to Milankovitch cycles.
33.
At a conference on climate change held in Boulder, Colorado in 1965, evidence supporting Milankovitch cycles triggered speculation on how the calculated small changes in sunlight might somehow trigger ice ages.
34.
Oxygen isotopes preserve a record of the effects of the Milankovitch cycles on climate change during the Quaternary, revealing an approximately 100, 000-year cyclicity in the Earth's climate.
35.
The layered deposits probably represent alternating cycles of dust and ice deposition caused by climate changes related to variations in the planet's orbital parameters over time ( see also Milankovitch cycles ).
36.
Predicted changes in orbital forcing suggest that in absence of human-made global warming the next glacial period would begin at least 50, 000 years from now ( see Milankovitch cycles ).
37.
The IPCC notes that Milankovitch cycles drove the ice age cycles, CO 2 followed temperature change " with a lag of some hundreds of years, " and that as a feedback amplified temperature change.
38.
As on Earth, Mars experiences Milankovitch cycles that cause its axial tilt ( obliquity ) and orbital eccentricity to vary over long periods of time, which has long-term effects on its climate.
39.
They are called Milankovitch cycles, after the Serbian mathematician Milutin Milankovitch, who proposed in the 1930s that such regularly occurring variations could explain why Earth's climate goes in and out of ice ages.
40.
Milankovitch cycles cannot be the sole factor responsible for the variations in climate since they explain neither the long term cooling trend over the Plio-Pleistocene, nor the millennial variations in the Greenland Ice Cores.
