The cataclysmic pole shift hypothesisis a pseudo-scientificclaim that there have been recent, geologically rapid shifts in the axis of rotationof Earth, causing calamities such as floods and tectonic events[1]or relatively rapid climate changes. There is evidence of precessionand changes in axial tilt, but this change is on much longer time ...
To compensate, either a leap second will have to be added to the end of a day multiple times during each month, or one or more consecutive leap seconds will have to be added at the end of some or all months. [12] 1,100 As Earth's poles precess, Gamma Cephei replaces Polaris as the northern pole star. [13] 10,000
Equinox. 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.
Polar motion of the Earth is the motion of the Earth's rotational axis relative to its crust. [ 2 ]: 1 This is measured with respect to a reference frame in which the solid Earth is fixed (a so-called Earth-centered, Earth-fixed or ECEF reference frame). This variation is a few meters on the surface of the Earth.

July 4 was declared the start date of the 2023-2024 El Niño event by the World Meteorological Organization (WMO). On July 20, the government of India – the main rice exporter in the world – banned the export of non-basmatirice, in order to seek to contain the rise in prices at the domestic level and guarantee its availability in the ...
On Wednesday, an annular solar eclipse created a "ring of fire" effect across parts of South America, according to NASA.. Annular solar eclipses, which occur every one to two years, happen when ...
