Global warming is a cause for concern because even small changes in the Earth’s temperature can have significant consequences. For example, if the Earth’s polar ice caps were to melt entirely, the resulting additional water in the oceans would flood many coastal cities. Would it appreciably change the length of a day? Calculate the resulting change in the duration of one day. Model the polar ice as having mass 2.30 X 1019 kg and forming two flat disks of radius 6.00 X 105 m. Assume the water spreads into an unbroken thin spherical shell after it melts.
