The geographic poles are defined by the points on the surface of Earth that are intersected by the axis of rotation. The pole shift hypothesis describes a change in location of these poles with respect to the underlying surface – a phenomenon distinct from the changes in axial orientation with respect to the plane of the ecliptic that are caused by precession and nutation, and is an ...
In the 1930s and 1940s, Cayce made many prophecies of cataclysmic events involving the whole planet, [4] with a series of "earth changes" occurring between 1958 and 1998. [5] He predicted that the polar axis would shift and that many areas that are now land would again become ocean floor, and that Atlantis would rise from the sea.
The envelope of gas surrounding the Earth changes from the ground up. Five distinct layers have been identified, the troposphere, stratosphere, mesosphere, thermosphere and exosphere.
The Images of Change project provides side-by-side photos of the same place over time to document the environment changes caused by nature and man. NASA's before and after images show Earth's ...
[45] [46] This is equivalent to a change of the semiminor axis of the planet's orbit from 99.95% of the semimajor axis to 99.88%, respectively. [47] Earth is passing through an ice age known as the quaternary glaciation, and is presently in the Holocene interglacial period. This period would normally be expected to end in about 25,000 years.

Earth’s inner core, a red-hot ball of iron 1,800 miles below our feet, stopped spinning recently, and it may now be reversing directions, according to an analysis of seismic activity.
The expanding Earth or growing Earth was a hypothesis attempting to explain the position and relative movement of continents by increase in the volume of Earth. With the recognition of plate tectonics in 20th century, the idea has been abandoned.
Orbital forcing is the effect on climate of slow changes in the tilt of the Earth's axis and shape of the Earth's orbit around the Sun (see Milankovitch cycles).These orbital changes modify the total amount of sunlight reaching the Earth by up to 25% at mid-latitudes (from 400 to 500 W/(m 2) at latitudes of 60 degrees).
