What is Global Change?

Global change refers to the many changes unfolding across our planet, including changes to climate, land, water, and ecosystems. Humans increasingly shape these changes and are a consequential part of the Earth system.

Global change research is the interdisciplinary effort to better understand these changes, why they happen, how they connect, and how we can work together toward sustainable solutions.
