In a year, many political et natural events such as riots, terror attacks, earthquakes and hurricanes happen. In a decade, you age, economical crisis happen, new technologies emerge. In a century, technological and cultural revolutions happen, some species vanish, a major natural catastrophe is bound to happen (major tsunami or earthquake, major volcanic explosion). In a millenia, human society is profoundly changed, rare events may have happened (such as a supernova, impact with a meteorite such as the Tunguska event). In a million years, continents drifted, new species appeared, human specie doesn't look like today (probably extinct), massive extinctions become probable. But in a billion years and further in the future, what sort of events are bound to happen here on Earth?
The main predictable future event is that the sun will swell up becoming more like a red giant star. That will fry everything here. (see http://en.wikipedia.org/wiki/Red_giant#The_Sun_as_a_red_giant)
The beginnings of the process may become important in a billion years or so.

The "et" was the clue. We have few Latin-speaking readers.
