Climate Change, Earth’s Orbit, Yugas


from http://earthguide.ucsd.edu/virtualmuseum/climatechange2/03_1.shtmlIn 1966, Broecker proposed a new time scale based on extrapolation of a 120,000-year date for the last major warm peak in the oxygen-isotope record, and he proclaimed his data was a close match to Milankovitch summer insolation.

- 120,000 years is 10 Mahayugas per Markandeya (Mahabharata).

- As per Aryabhatta, the years that Markandeya talks about are divine years.

- 1 divine year = 360 human (earth years).

- Kaliyuga duration = 1200(360) = 432000 earth years

- Mahayuga duration = satya + treta + dwapara + kali = 12000 (360) = 4 320 000

- 1 Kalpa (brahma’s day) = 4 320 000 000 earth years

** the age of the earth is 4.6 billion years = 4 600 000 000

** Notice that the earth’s age as computed today is of the same order of magnitude as Brahma’s day or a kalpa. Kalpa is the time period related to creation

“A few years later in 1970, Broecker and his student Jan van Donk elaborated on the “mode switch” theme and postulated rapid transitions from periods of maximum glaciation to the following warm periods. They identified 6 such “terminations” for the last 440,000 years, which define 5 full cycles for the last 400,000 years, for an average duration of 80,000 years per cycle. With this work, Broecker introduced the notion that the major ice age cycles of the Pleistocene were roughly 100,000 years long, and that glaciations grew gradually and ended abruptly, a pattern described as “sawtooth” cycles. “

“The first distinct magnetic reversal of the core, called the “Brunhes-Matuyama” reversal, was found to occur just before Isotope Stage 19, the 19th warm peak (counting the present peak as Number 1). The reversal had been dated (on land) as about 700,000 years before present. It was now possible to assign ages to each isotope stage, by interpolation. Stage 5e came out near 123,500 years.”

Per Aryabhatta,

We are ~5000 years into Kali Yuga, viz at the beginning of the same. The previous Yuga of Dwapara is twice as long as kali yuga and was 864000 years long.

The magenetic reversal would have taken place after 70% of Dwapara Yuga had taken place, ie in the 3rd to 4th quarter (pada) of Dwapara Yuga.

“When Fourier analysis was applied to deep-sea records in 1975, it emerged that the oxygen-isotope series contained strong cycles with periods near 100,000 years, 41,000 years, and 23,000 years. These are precisely the periods expected if Earth’s orbital elements (eccentricity, obliquity, and precession) govern ice-age climates, as proposed by Milankovitch Theory. Thus, there could be no more doubt that orbital elements had to be considered as important drivers of climate on long time scales.

The following years saw a profusion of information and discussion on this subject. A revolution in thought was being made, and our understanding of Earth history would never be the same. The orbit-climate connection squarely puts Earth’s climate into the context of the fluctuating gravitational field of the solar system. The planets wandering across the heavens may not control our individual lives, as once thought during the early days of astronomy, but they do control the course of large-scale climate fluctuations which form the backdrop for the evolution of the ice-age megafauna and for our own species.”
