There are more elegant ways of doing it, as described in the question linked in the comments, but the simplest way is to define a RequireJS module with an object literal to hold the shared state:

define('sharedstuff', [], {tree: "original value"});

And then from other module you can require it:

require(['sharedstuff'], function(sharedstuff) {
    sharedstuff.tree = "new value";
};

And if from yet another module you require it, RequireJS will not reload a fresh copy but will instead give you the already loaded version with your shared value populated:

require(['sharedstuff'], function(sharedstuff) {
    console.log(sharedstuff.tree) // should be "new value"
};
