An often-cited 1980 orbital model by Imbrie predicted "the long-term cooling trend that began some 6,000 years ago will continue for the next 23,000 years." [ 46 ] Another work [ 47 ] suggests that solar insolation at 65° N will reach a peak of 460 W·m −2 in around 6,500 years, before decreasing back to current levels (450 W·m −2 ) [ 48 ...
Given the different Sun incidence in different positions in the orbit, it is necessary to define a standard point of the orbit of the planet, to define the planet position in the orbit at each moment of the year w.r.t such point; this point is called with several names: vernal equinox, spring equinox, March equinox, all equivalent, and named considering northern hemisphere seasons.
A solar equinox is a moment in time when the Sun crosses the Earth's equator, which is to say, appears directly above the equator, rather than north or south of the equator. On the day of the equinox, the Sun appears to rise "due east" and set "due west". This occurs twice each year, around 20 March and 23 September. [a]
Properly changing your body composition requires nutritional precision down to the gram, hard—and we mean hard—lifting sessions, optimal recovery and nutrition, and plenty of patience.
To see change in your body composition and strength gains, do this workout 2 to 3 times a week for 6 to 8 weeks, making sure to increase the weights or rep counts every other week (AKA ...

The Persian calendar begins each year at the northward equinox, observationally determined at Tehran. [15] The Indian national calendar starts the year on the day next to the vernal equinox on 22 March (21 March in leap years) with a 30-day month (31 days in leap years), then has 5 months of 31 days followed by 6 months of 30 days. [15]
The September equinox (or southward equinox) is the moment when the Sun appears to cross the celestial equator, heading southward. Because of differences between the calendar year and the tropical year, the September equinox may occur from September 21 to 24. At the equinox, the Sun as viewed from the equator rises due east and sets due west ...
