Slice of (human) Life

Continuing on the rather gloomy theme on mankind’s place in the Universe, here’s a little summary I made of the Earth’s future from Ward and Brownlee’s “The life and death of planet Earth”

Basically:

The planet is 4.5 billion years old will exist for about another 7.6 billion before being eaten by the Sun.

Modern humans (hom sap sap) emerged 200,000 years ago. (About 22 thousandth of the age of the Earth) and will be extinct within the next 15,000 to 80,000 years as the climate returns to Ice Age average.

On any reasonable scale of Earth’s existence humans don’t even get on the graph.
