Serious answer for a serious question – yes, it is natural. But no – not earthquakes and definitely NOT climate change (although they are slightly related).
The slowing is actually caused by tidal friction between the Earth and the Moon. (Which also has the Moon very slowly getting further from the Earth; about 4 centimeters further away every year.) Here’s a good link: http://www.physlink.com/Education/AskExperts/ae695.cfm
Now – SOME of the energy released by SOME earthquakes is also caused by this tidal friction; but that has no effect on the rotation of the Earth.
“Climate change” (the real thing, the cycles between big ice caps and little ice caps, not the faux garbage spouted by the Church of Gore) affects the motion of the Earth slightly – as the mass on each spot of the Earth changes due to ice caps growing and shrinking, it wobbles a tiny bit. (Sigh, my Google-fu is not up to finding a link for that one – all mixed up with “wobbling” politicians, crank sites about aliens making the Earth wobble, the Wobblies political movement…) But the principle is the same as adding weight (or pressure) to one spindle end of a spinning top without a corresponding opposite pressure on the other end.
My comment was sarcastic and trying to rib the liberals.

There has got to be a BH0 joke in here somewhere.

If a news paper refuses to announce a gay couples wedding, is that discrimination?
So are you saying institutions and ideas should never change just because they've been around for a long time? Slavery was the law if the land in almost every country for thousands of years. Should the laws regarding slavery not have been changed just because it was a long-held institution?
