Understanding and predicting the complexity of Earth's natural changes and variations as well as its responses to human interference, management and alteration requires many disciplines of science working together. We approach our research as a system of sciences, where the Earth system is one of several organized groups of components that interact with one another.
Our key components within the Earth system are the atmosphere, cryosphere, land and ocean, and each of these components contain many interactive processes. Each process is a series of actions—governed by fundamental laws of physics, chemistry, fluid dynamics, geology and biology—that occur to produce a condition (e.g. temperature), movement (e.g. wind or river flow), and/or exchange (e.g. evaporation).
It is only through the cooperation and collaboration of our researchers and expertise in all areas of these scientific disciplines that the MIT Earth System Model (MESM) can provide credible and reliable insights into the future.
