milankovitch theory การใช้

• There are other recent studies that indicate the validity of the original Milankovitch theory.
• These parameters include the precession of the equinoxes, obliquity, and eccentricity as put forth by Milankovitch theory.
• In 1999, it was shown that variations in the isotopic composition of oxygen in the sediments at the bottom of the ocean follow Milankovitch theory.
• The timing of past glacial periods coincides very well with the predictions of the Milankovitch theory, and these effects can be calculated into the future.
• According to the Milankovitch theory, these factors cause a periodic cooling of Earth, with the coldest part in the cycle occurring about every 40, 000 years.
• A strict application of the Milankovitch theory does not allow the prediction of a " sudden " ice age ( rapid being anything under a century or two ), since the fastest orbital period is about 20, 000 years.
• A strict application of the Milankovitch theory does not allow the prediction of a " rapid " ice age onset ( i . e ., less than a century or two ) since the fastest orbital period is about 20, 000 years.
• The "'100, 000-year problem "'( " 100 ky problem ", " 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 past 800, 000 years.
• Unfortunately, even though I am a climate physicist of 40 years experience, engaged on writing a popular book on this subject, I cannot yet say I understand Milankovitch theory as described in this article ( or any other popular books on the subject ) well enough to write a simple but authoritative account of it for my readers.
• James Hansen's book, " Storms of My Grandchildren " make it clear that our understanding of Ice Ages, which has come about from a combination of Milankovitch Theory with much hard work by geologists on coring and complex analyses of those cores, is at the centre of our understanding of what is likely to happen to us as Global Warming picks up pace.
