...in 500 million years. Better prepare!

We thank the Sun for giving us energy. Without it, thered be no life on Earth. Its ironic, then, that the Sun will eventually kill all life on Earth.
Thats because the Sun is slowly heating up.
One of the most fascinating books about this topic is The Life and Death of Planet Earth by Peter Ward and Donald Brownlee. In their book, they chronicle how Suns energy output is slowly increasing. In as soon as 500 million years, temperatures on Earth will rise to the point that most of the world will be a desert. The largest creatures wont be able to survive anywhere but the relatively cooler poles.
Over the course of the next few billion years, evolution will seem to go reverse. The largest organisms and least heat tolerant animals will die out, leaving hardy insects and bacteria. Finally, itll be so hot on the surface of the Earth that the oceans will boil away. Therell be no place to hide from the terrible temperatures. Only the organisms that live deep underground will survive, as they have already for billions of years.
