WHY IS EARTH'S ROTATION SLOWING DOWN?

Originally an Earth day was around six hours long, and the moon was much closer to us.
 
With Global Temperatures increasing, glaciers and ice sheets are melting, causing sea levels to begin to swallow cities and islands across the world.

A new study confirms that changing sea levels also affect Earth's rotation, because glaciers contain a huge amount of mass near the poles, close to The Earth's axis of rotation, which runs from pole to pole. When glaciers melt, the melt water ends up in oceans, wich have most of their volume near the Equator, farther away from the Earth's axis.

 One of the causes is the rise in the Earth's crust near the poles once it was no longer pressed down by the weight of the ice sheets from the last ice age.A phenomenon called post-glacial rebound that tends to speed down the Earth's rotation.

 
Other of the causes is the pull of the moon, wich tends to slow down the rotation of the Earh and makes the moon rotate quicker.

The principle cause of the slowing down of the Earth's rotation is the Global Warming, the constant increasing of the level of the sea, and the little amount of ice in the poles.

To prevent the slowing down of the rotation of the Earth, we have to contaminate less, so that the Global Warming stops.
