- For several hundred thousand years, the Sahara has alternated between desert and savanna grassland in a 20,000-year cycle caused by the precession of Earth’s axis (about 26,000 years) as it rotates around the Sun, which changes the location of the North African monsoon.
- Grover Cleveland (allthetropes.org)
Grover Cleveland (born Stephen Grover Cleveland) was the only American president to hold two non-consecutive terms, as the 22nd and 24th president (1885–89, 1893–97). Benjamin Harrison was the 23rd president, winning a bizarre race in 1888 in which Cleveland won the popular vote but Harrison prevailed in the Electoral College. Cleveland was also the second American president to get married while in office, and the only one to marry in the White House itself. He was also the only Democratic president in a period (1869-1913) of Republican executive dominance.

The Sahara (/səˈhɑːrə/, /səˈhɛrə/) is a desert spanning across North Africa. With an area of 9,200,000 square kilometres (3,600,000 sq mi), it is the largest hot desert in the world and the third-largest desert overall, smaller only than the deserts of Antarctica and the northern Arctic.
