Global warming is a cause for concern

Reference no: EM13656261

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 areas. Model the polar ice as having a combined mass of 2.10*1019 kg and forming two flat discs of radius 5.20*10⁵ m. Calculate the resulting change in the duration of one day both in seconds and as a percentage.
