Carol mentioned to me that apparently the recent tsunami disaster in Asia has caused a change in the Earth's rotation speed and introduced a "wobble".
Such a terrible tragedy. A reminder of the terrible power of nature. Anyone wishing to donate might consider contacting the Canadian Red Cross. The ICRC has also a site to help in searching for people in the affected areas. The aim of the ICRC's familylinks website is to help those separated by conflict or disaster to find information about their loved ones in order to restore contact.
And if you're thinking that this sort of disaster doesn't affect you. Read this.
