One of the core value propositions of React is one way data flow. Among other benefits, it makes it easy for developers to reason about as they trace the data flow. You don't want child-child communication, instead I would suggest structuring your app such that the parent can pass data to both children.

Any global variables in most cases is bad practice in React applications.

If you have some data, which should be used by many components, consider using some Flux library like Redux.
