The effective acceleration of gravity at the poles is 980.665 cm/sec/sec while at the equator it is 3.39 cm/sec/sec less due to the centrifugal force. If you weighed 100 pounds at the north pole on a spring scale, at the equator you would weigh 99.65 pounds, or 5.5 ounces less.

Rats, there is no adjustments on clocks anymore. I remember the old Ben clocks and a few others had that on them. I suppose we will all be dependent now on satellite input to keep our clocks from losing a second a month.
I suppose this will be used as a sales ploy to sell special new improved clocks and the government will spend a billion dollars upgrading it's systems to make sure their clocks are not a second a month off.
Global Tardation or Rotation Change ?
If the rotation is slowing down shouldn't there be less earthquakes...
It's the change in speed, more or less
I think that as the world warms and there's more water the Earth has to slow down to compensate. Thoughts?

there you have it:.. "official science"
Yeah, but what are we going to call it .... Global Tardation or Rotation Change
No. Tidal forces are not "distributed" according to the malleability of the matter. Without oceans, the tidal forces of the Sun and Moon would be the same as they are with the oceans. Their effects on solid matter would be no different than they are.
Our moon would do a lot of damage if water wasn't on the planet and able to move.
No, you have it backwards. An increase in orbital velocity would result in an increase in the rate of rotation. But the Earth is not tidally locked to the Sun so it doesn't matter anyway.
What we are seeing is a trade off between earths rotation and its orbital velocity they are linked. If the earths rotation around the sun increases in velocity earths spin decreases.

I could be wrong but this is my guess. I'm not a scientist but I think that as the world warms and there's more water the Earth has to slow down to compensate. Thoughts?

You seem to be confusing forces and energy. Tidal forces affect all matter equally (according to the gravity gradient). Because water is able to be deformed more (because it is liquid), it does not mean that there is less force applied to solid material.
Tides disperse this energy more effectively then say rock
Yes, you did get it backwards but you claim a causal relationship between orbital velocity and planetary rotation. If this is not caused by tidal effects, what causes it?
And no i didnt get it backwards at all the two are corelated and has nothing to do with being tidally locked with the sun odd conceptyouhave.

What you said was this:

What, in that article, implies this?
No, it doesn't. The only thing that "redistributes" tidal forces are the positions of the Sun and Moon relative to the Earth.
Luckily water redistributes tidal forces.

The article you linked says that changes in the distribution of water (and atmospheric) mass change Earth's angular momentum (and thus the length of its day).
Fresh fears have been raised that a huge earthquake is about to hit California after a swarm of recent tremors.
In the last week 134 earthquakes have hammered a three-mile stretch around Monterey County on the San Andreas fault.
Of those earthquakes, 17 were stronger than 2.5 magnitude and six of them were stronger than 3.0, with more tremors expected in the coming weeks, experts warn.
It follows fears raised last week that the 'Big One' is about to hit after a series of ten 'mini quakes' struck the same area.
The swarm included one 4.6-magnitude quake that was felt in San Francisco more than 90 miles (145 km) away.
