How has the Earth changed in the last 100 years?

What will happen to Earth's surface in the future?

In the future, Earth will be warmer, precipitation events will be more extreme, global mean sea level will rise, and many arid and semiarid regions will be drier. Human modifications of landscapes will also occur at an accelerated rate as developed areas increase in size and population density.

How does the Earth system change over time?

Earth and its atmosphere are continuously altered. Plate tectonics shift the continents, raise mountains and move the ocean floor while processes not fully understood alter the climate. Such constant change has characterized Earth since its beginning some 4.5 billion years ago.

How hot will it be by 2100?

In general, scientists think that the planet is going to get anywhere from 3.5 to more than 8-degrees hotter by the year 2100, but somewhere in the middle of that range is the most likely scenario.
