Earth science

Many scientists are now starting to use an approach known as Earth system science which treats the entire Earth as a system in its own right, which evolves as a result of positive and negative feedback between constituent systems.

The systems approach, enabled by the combined use of computer models as hypotheses tested by global satellite and ship-board data, is increasingly giving scientists the ability to explain the past and possible future behaviour of the Earth system.
